If You Feel LED to Decorate Your Home


Get it? LED vs led. Of course you do, and that’s exactly our point.It seems the Joneses are all getting those brightly colored LED(Light Emitting Diode) lights to decorate their home. Maybeyou’ve seen them and have wondered why these LED lights seem to be everywhere. We have your answer.
 
There are several good reasons why more and more LED lights will be lining the rooftops, bushes and trees of houses in your neighborhood. Turns out, those bright beacons of multicolored light are up to 90% more energy efficient (or “greener”) and are therefore a much safer way to decorate for the holidays.That’s because the more efficient a bulb is, the less heat it produces, so a more efficient bulb is a safer bulb (fire safety).Oddly enough, the more LED lights that go up near you, the fewer sirens and flashing lights you’ll witness in your neighborhood (due to electric Christmas décor fires). And while we’re on it,you might notice that many of today’s police and other emergency response vehicles are using the same LED lights becauseLED lights are so incredibly bright.

While LED lights for Christmas decorations have only been out for a few years, it’s only been recently that the price tag has been right for the average American household. Having said that, the LED lights are still a little pricier than the incumbent filament bulb style. But the LED bulb not only outshines its competition, it far outlives traditional filament bulbs too. The life of LED holiday lights seems to be up for debate because they last so long; 20 years by some estimations, if they’re only used once a year for a month. So now you can start to see why Lowder New Homes would encourage you to consider switching your bright-light stash over to LED. It will make a difference on your energy bill if you’re one of those families who uses thousands of lights for a month or two. And even if you only plan on a few strands here and there, the fire safety is well worth the investment. So string up those lights however you like. We just hope you’ll remember these facts if you feel LED to decorate your home.

Glowing LED Snowboarder


I’ve heard about integrating LEDs into clothing, but this is the first time that I’ve seen asnowboarder completely lit up like a Christmas tree. In the short film L.E.D. Surfer, created by filmmaker Jacob Sutton for Nowness, we get to watch Artec pro snowboarder William Hughes going down the French Alps, covered head-to-toe in bright LEDs.

LED decoration for our home part 1


Lighted glass blocks for decoration
Manufacturers compete with each other in creating artistic glass blocks of surface texture, with the models in different colours. This results in an increasing interest. The company has new solution that will make the same wall of glass blocks additionally illuminated subtly illuminates our room. We no longer need to invest in expensive colourful blocks.

Decoration with illuminated blocks

Simple enough backlit frosted glass blocks, where the colour, intensity, rate of change of the colour will change according to our mood, sitting comfortably on the couch.
As with all projects based on this LED lighting also features high-energy efficiency.
Why Illuminated Glass blocks?

 

Kitchen decoration

 The reasons for decoration with glass blocks are many. Just like other products, that also Soled is a modern form of decorative lighting based on LED technology. LED lighting used to change the highlight colour, and dynamic settings, or a smooth change of colour. Thanks to our face every day, part of the wall can light up to a different colour. This solution can easily be replaced by other light sources used in the home such as lamps, lighting for watching TV, and romantic lighting in the bedroom or bathroom.

Decoration with glass blocks

 Substituting Illuminated Glass blocks for decoration in the wall separating the two rooms so you really get the two of them. The wall of glass blocks, we can highlight the very low expenditure of energy. 10 illuminated glass blocks is only 7 W of power.
This solution is for every budget.

How to Replace a 12-V Bulb With an LED



Dimming LED Light Bulbs is one way to help save on electricity costs and it is another way to add dimension and creative flair to electronic design projects.The brightness of an LED is dependent on the amount of electric current that flows through it. However, small changes in electric current may change the brightness levels considerably. This means that you must be careful to select a resistor that will adequately, but not excessively, dim your lights.Replacing a 12-volt light bulb with an LED tubes may, at first, seem like an expensive switch. LED light bulbs do, in fact, cost more than the typical incandescent light bulb. However, LED light bulbs last longer than their incandescent counterparts, produce less heat and use less energy.
On top of these advantages, you'll find that installing a new LED light bulb is as quick and easy as replacing a typical light bulb.LED bulbs have many advantages over other types of bulbs, with one of the biggest being that LED bulbs they have a much longer life span than any other type of light bulb. However, LED bulbs, like every other bulb, will eventually burn out. When this happens, the process of changing the bulb is relatively simple to do.One of the major drawbacks to incandescent light bulbs is the amount of energy they convert to heat. With halogen bulbs, about 90 percent of the energy used is converted to radiant heat. With LED lighting, however, only a fraction of the LED Downlight energy used is converted to wasted heat.The headquarters of Sylvania is in Danvers, Mass. Sylvania produces fluorescent, incandescent and high-intensity discharge lamps. The company offers LED light bulbs. For example, the Ultra PAR38 Dimmable can decrease energy consumption up to 76 percent and can run at least 50,000 hours at 70 percent lumen. You can use the light bulb indoors or outdoors.Westinghouse produces LED light bulbs. For example, the Westinghouse Nanolux LED light bars last for up to 100,000 hours and come in one and three watts. The bulbs replace 7- to 20-watt incandescent lights. The lights are for both outdoor and indoor use for pendants, lanterns and strand lights.

LED use in car light modification


Talk about light modification, in fact nothing but the following methods:
first,increasing the coriginal car light bulb power
Generally we common car before the lights in the wattage 55 W or so, basically can meet most of the lighting needs. But some owners think enough bright lights, so he will keep the light bulb with 60 W, 100 W, even higher, at this moment the lamp brightness while dramatically, but hidden danger has greatly increased.
Because the wattage increase, current and heat increase exponentially, leading to aging and lamp holder melting speed up the lamps and lanterns, back to generators, fuse, battery bring big burden, many spontaneous combustion of the vehicles are is because of he modified cause. Therefore, the lamp upgrade should not increase the original car headlight wattage as the prerequisite. Basically we don't suggest you use this way to carry bright lights, if determined to increase light bulb wattage, we also advise you will power control within 10%.
Second, and outfit import light bulb
Always listen to some light manufacturer claims, their light bulb in power consumption power under the same, increased by more than 50% brightness, and all of this is just need to change a light bulb. If you see similar advertising, don't believe all, because the author is one of the victims.
Change to pack import light bulb, brightness does have a small ascension than before, and the light color can also be there are multiple choice, if you look in the eyes son good night, and not ready to hit a pen lamp malicious words, it should be a good choice, the most important is such modification would never cause inspection unnecessary trouble. So we recommend primary geek reference.
Three, adding the lights brighten up device
When you shop puts forward to want to spend to modified less money to light, the businessman often recommend to you a call lights brighten up the thing is, no matter use to listen to the tube the stories you will understand.
A close friend just change the headlight lighten the device, want to prove to me to spend a little of his big cheap, and meet the midnight than light out. The results we find the car parked in the night side by side the district's parking lot, I didn't do any lights in the reconstruction of the jetta (quotation; picture) and he is with a brighten up the SaiOu went to a stop, and at the same time open a YuanGuangDeng than, I that friend without further ado go make a turn, and don't ask to lighten up about the....... He bit his teeth and said: "next time, do not change the xenon headlamps, brother would never see you again!" Heard later he went to city auto parts, spend 50 yuan for the original light back be outright. Through this experience tell me, don't superstitious so-called advanced equipment, lighten the device may help some brighten up effect, but absolutely no boast the businesses that "god"!
Four, and outfit lens lighting system
Nowadays is very popular to modify a kind of call "angel eye" lens lighting assembly. Is modeled on a BMW car lighting system, in conventional lens lighting basis, and with a lap of LED to LED, far see within four lights is circle.
In fact the headlight of a burning assembly would have spread, this kind of lighting system than traditional reflected light illumination has better effect, concentrated light, the light bulb through the lens of the reflected more porous, and light and shade the neat line clear, and on to the traffic will not have a strong sense of dazzling.
But the cost of the modified weakness is relatively high, cheaper also want to 23000 yuan, does not apply to all of the owners, and now the production quality also is the good and bad are intermingled manufacturer, poor quality of lenses assembly is likely not a strong light effect, but will also bring to the security hidden danger.
Five, the modification xenon headlamps
Xenon lamp is really just a referred to, because the market price of 1500 yuan from domestic, tens of thousands of dollars to import HID all call xenon lamp, so we buy when the choice to double careful.

Will LED Light Bulbs Help You Fall Asleep?


If you fly to Asia on the new Boeing 787 Dreamliner, you might find it a wee bit easier to fall asleep on the way.
Although LED light bulbs have largely been touted by advocates as a way to curb energy consumption, many manufacturers have begun to discover that the 搊ther?attributes of these chips條ong lifetimes, low maintenance requirements, precise control and communications capabilities?could actually emerge as the strongest selling points.
A properly engineered LED light bulbs, in other words, could help you sleep.揧ou can reset circadian rhythms and evoke behavioral responses,?said Dr. George Brainard, a professor of neurology at the Jefferson Medical College at ThomasJefferson University, who added that health could be one of the common packaging and branding qualities, like output and watts, in a decade or two.
The first consumer 揵iological specific lights?could even start to hit the market in about two years, says Fred Maxik, one of the founders of Lighting Science Group, which specializes in LED light bulbs.
Lighting Science has made LED light bulbs for testing circadian rhythm impacts for both NASA and aircraft engineers. (See photo.) The company currently works with Google on a bulb that dims and brightens as you approach with an Android phone. Bulbs tuned to kill germs朥V light can be deadly to microbes杕ight appear four to five years beyond sleepy bulbs.
The potential to exploit LED light bulbs as sleeping aids derives largely from the fact that LEDs can be programmed to emit light at precise wavelengths, colors and tones. LED light bulbs, after all, are digital semiconductors. Traditional light bulbs produce light by heating exotic gases or pieces of metal inside of sealed tubes: they are the last vestige of the 132-year old vacuum tube era. Controlling them requires filters and the tribal wisdom of lighting designers.
揂n LED is a light source, but it is an infinitely controllable source,?said Zach Gentry, an executive at Enlighted, which combines LED light bulbs with temperature, light and occupancy sensors for monitoring energy consumption and physical activity in office buildings.
Throughout most of human history, people began their workday when the sun crossed the horizon and went to bed after night descended.

Happy Traditional Chinese Lantern Festival



Lantern Festival

The Lantern Festival falls on the 15th day of the 1st lunar month, usually in February or March in the Gregorian calendar. As early as the Western Han Dynasty (206 BC-AD 25), it had become a festival with great significance.

This day's important activity is watching lanterns. Throughout the Han Dynasty (206 BC-AD 220), Buddhism flourished in China. One emperor heard that Buddhist monks would watch sarira, or remains from the cremation of Buddha's body, and light lanterns to worship Buddha on the 15th day of the 1st lunar month, so he ordered to light lanterns in the imperial palace and temples to show respect to Buddha on this day. Later, the Buddhist rite developed into a grand festival among common people and its influence expanded from the Central Plains to the whole of China.


Till today, the lantern festival is still held each year around the country. Lanterns of various shapes and sizes are hung in the streets, attracting countless visitors. Children will hold self-made or bought lanterns to stroll with on the streets, extremely excited.

"Guessing lantern riddles"is an essential part of the Festival. Lantern owners write riddles on a piece of paper and post them on the lanterns. If visitors have solutions to the riddles, they can pull the paper out and go to the lantern owners to check their answer. If they are right, they will get a little gift. The activity emerged during people's enjoyment of lanterns in the Song Dynasty (960-1279). As riddle guessing is interesting and full of wisdom, it has become popular among all social strata.


People will eat yuanxiao, or rice dumplings, on this day, so it is also called the "YuanxiaoFestival."Yuanxiao also has another name, tangyuan. It is small dumpling balls made of glutinous rice flour with rose petals, sesame, bean paste, jujube paste, walnut meat, dried fruit, sugar and edible oil as filling. Tangyuan can be boiled, fried or steamed. It tastes sweet and delicious. What's more, tangyuan in Chinese has a similar pronunciation with "tuanyuan”, meaning reunion. So people eat them to denote union, harmony and happiness for the family.

In the daytime of the Festival, performances such as a dragon lantern dance, a lion dance, a land boat dance, a yanggedance, walking on stilts and beating drums while dancing will be staged. On the night, except for magnificent lanterns, fireworks form a beautiful scene. Most families spare some fireworks from the Spring Festival and let them off in the Lantern Festival. Some local governments will even organize a fireworks party. On the night when the first full moon enters the New Year, people become really intoxicated by the imposing fireworks and bright moon in the sky.

Our Bgocled may you happy  Lantern Festival.

Facebook Founder's Open Letter: to Give Everyone a Voice

“There is a huge need and a huge opportunity to get everyone in the world connected, to give everyone a voice and to help transform society for the future”
 


Facebook CEO and founder Mark Zuckerberg tucked a letter into the company’s filing for an initial public offering, in which he explains the reason why he created the company, and its mission.
“There is a huge need and a huge opportunity to get everyone in the world connected, to give everyone a voice and to help transform society for the future,” the enigma said.
The social network filed on Wednesday to raise a targeted 5 billion U.S. dollars in a hotly anticipated initial public offering, setting the stage for Silicon Valley’s biggest-ever IPO.
Shares of Morgan Stanley, who was appointed as the principal underwriter, soared 4 percent in Wednesday’s trading.
Here below is Mark Zuckerberg’s letter in full:
LETTER FROM MARK ZUCKERBERG
Facebook was not originally created to be a company. It was built to accomplish a social mission — to make the world more open and connected.
Facebook Files $5B IPOWe think it’s important that everyone who invests in Facebook understands what this mission means to us, how we make decisions and why we do the things we do. I will try to outline our approach in this letter.
At Facebook, we’re inspired by technologies that have revolutionized how people spread and consume information. We often talk about inventions like the printing press and the television — by simply making communication more efficient, they led to a complete transformation of many important parts of society. They gave more people a voice. They encouraged progress. They changed the way society was organized. They brought us closer together.
Today, our society has reached another tipping point. We live at a moment when the majority of people in the world have access to the internet or mobile phones — the raw tools necessary to start sharing what they’re thinking, feeling and doing with whomever they want. Facebook aspires to build the services that give people the power to share and help them once again transform many of our core institutions and industries.
There is a huge need and a huge opportunity to get everyone in the world connected, to give everyone a voice and to help transform society for the future. The scale of the technology and infrastructure that must be built is unprecedented, and we believe this is the most important problem we can focus on.
We hope to strengthen how people relate to each other.
Even if our mission sounds big, it starts small — with the relationship between two people.
Personal relationships are the fundamental unit of our society. Relationships are how we discover new ideas, understand our world and ultimately derive long-term happiness.
At Facebook, we build tools to help people connect with the people they want and share what they want, and by doing this we are extending people’s capacity to build and maintain relationships.
People sharing more — even if just with their close friends or families — creates a more open culture and leads to a better understanding of the lives and perspectives of others. We believe that this creates a greater number of stronger relationships between people, and that it helps people get exposed to a greater number of diverse perspectives.
By helping people form these connections, we hope to rewire the way people spread and consume information. We think the world’s information infrastructure should resemble the social graph — a network built from the bottom up or peer-to-peer, rather than the monolithic, top-down structure that has existed to date. We also believe that giving people control over what they share is a fundamental principle of this rewiring.
We have already helped more than 800 million people map out more than 100 billion connections so far, and our goal is to help this rewiring accelerate.
We hope to improve how people connect to businesses and the economy.
We think a more open and connected world will help create a stronger economy with more authentic businesses that build better products and services.
As people share more, they have access to more opinions from the people they trust about the products and services they use. This makes it easier to discover the best products and improve the quality and efficiency of their lives.
One result of making it easier to find better products is that businesses will be rewarded for building better products — ones that are personalized and designed around people. We have found that products that are “social by design” tend to be more engaging than their traditional counterparts, and we look forward to seeing more of the world’s products move in this direction.
Our developer platform has already enabled hundreds of thousands of businesses to build higher-quality and more social products. We have seen disruptive new approaches in industries like games, music and news, and we expect to see similar disruption in more industries by new approaches that are social by design.
In addition to building better products, a more open world will also encourage businesses to engage with their customers directly and authentically. More than four million businesses have Pages on Facebook that they use to have a dialogue with their customers. We expect this trend to grow as well.
We hope to change how people relate to their governments and social institutions.
We believe building tools to help people share can bring a more honest and transparent dialogue around government that could lead to more direct empowerment of people, more accountability for officials and better solutions to some of the biggest problems of our time.
By giving people the power to share, we are starting to see people make their voices heard on a different scale from what has historically been possible. These voices will increase in number and volume. They cannot be ignored. Over time, we expect governments will become more responsive to issues and concerns raised directly by all their people rather than through intermediaries controlled by a select few.
Through this process, we believe that leaders will emerge across all countries who are pro-internet and fight for the rights of their people, including the right to share what they want and the right to access all information that people want to share with them.
Finally, as more of the economy moves towards higher-quality products that are personalized, we also expect to see the emergence of new services that are social by design to address the large worldwide problems we face in job creation, education and health care. We look forward to doing what we can to help this progress.
Our Mission and Our Business
As I said above, Facebook was not originally founded to be a company. We’ve always cared primarily about our social mission, the services we’re building and the people who use them. This is a different approach for a public company to take, so I want to explain why I think it works.
I started off by writing the first version of Facebook myself because it was something I wanted to exist. Since then, most of the ideas and code that have gone into Facebook have come from the great people we’ve attracted to our team.
Most great people care primarily about building and being a part of great things, but they also want to make money. Through the process of building a team — and also building a developer community, advertising market and investor base — I’ve developed a deep appreciation for how building a strong company with a strong economic engine and strong growth can be the best way to align many people to solve important problems.
Simply put: we don’t build services to make money; we make money to build better services.
And we think this is a good way to build something. These days I think more and more people want to use services from companies that believe in something beyond simply maximizing profits.
By focusing on our mission and building great services, we believe we will create the most value for our shareholders and partners over the long term — and this in turn will enable us to keep attracting the best people and building more great services. We don’t wake up in the morning with the primary goal of making money, but we understand that the best way to achieve our mission is to build a strong and valuable company.
This is how we think about our IPO as well. We’re going public for our employees and our investors. We made a commitment to them when we gave them equity that we’d work hard to make it worth a lot and make it liquid, and this IPO is fulfilling our commitment. As we become a public company, we’re making a similar commitment to our new investors and we will work just as hard to fulfill it.

The Hacker Way
As part of building a strong company, we work hard at making Facebook the best place for great people to have a big impact on the world and learn from other great people. We have cultivated a unique culture and management approach that we call the Hacker Way.
The word “hacker” has an unfairly negative connotation from being portrayed in the media as people who break into computers. In reality, hacking just means building something quickly or testing the boundaries of what can be done. Like most things, it can be used for good or bad, but the vast majority of hackers I’ve met tend to be idealistic people who want to have a positive impact on the world.
The Hacker Way is an approach to building that involves continuous improvement and iteration. Hackers believe that something can always be better, and that nothing is ever complete. They just have to go fix it — often in the face of people who say it’s impossible or are content with the status quo.
Hackers try to build the best services over the long term by quickly releasing and learning from smaller iterations rather than trying to get everything right all at once. To support this, we have built a testing framework that at any given time can try out thousands of versions of Facebook. We have the words “Done is better than perfect” painted on our walls to remind ourselves to always keep shipping.
Hacking is also an inherently hands-on and active discipline. Instead of debating for days whether a new idea is possible or what the best way to build something is, hackers would rather just prototype something and see what works. There’s a hacker mantra that you’ll hear a lot around Facebook offices: “Code wins arguments.”
Hacker culture is also extremely open and meritocratic. Hackers believe that the best idea and implementation should always win — not the person who is best at lobbying for an idea or the person who manages the most people.
To encourage this approach, every few months we have a hackathon, where everyone builds prototypes for new ideas they have. At the end, the whole team gets together and looks at everything that has been built. Many of our most successful products came out of hackathons, including Timeline, chat, video, our mobile development framework and some of our most important infrastructure like the HipHop compiler.
To make sure all our engineers share this approach, we require all new engineers — even managers whose primary job will not be to write code — to go through a program called Bootcamp where they learn our codebase, our tools and our approach. There are a lot of folks in the industry who manage engineers and don’t want to code themselves, but the type of hands-on people we’re looking for are willing and able to go through Bootcamp.
The examples above all relate to engineering, but we have distilled these principles into five core values for how we run Facebook:
Focus on Impact
If we want to have the biggest impact, the best way to do this is to make sure we always focus on solving the most important problems. It sounds simple, but we think most companies do this poorly and waste a lot of time. We expect everyone at Facebook to be good at finding the biggest problems to work on.
Move Fast
Moving fast enables us to build more things and learn faster. However, as most companies grow, they slow down too much because they’re more afraid of making mistakes than they are of losing opportunities by moving too slowly. We have a saying: “Move fast and break things.” The idea is that if you never break anything, you’re probably not moving fast enough.

Be Bold
Building great things means taking risks. This can be scary and prevents most companies from doing the bold things they should. However, in a world that’s changing so quickly, you’re guaranteed to fail if you don’t take any risks. We have another saying: “The riskiest thing is to take no risks.” We encourage everyone to make bold decisions, even if that means being wrong some of the time.
Be Open
We believe that a more open world is a better world because people with more information can make better decisions and have a greater impact. That goes for running our company as well. We work hard to make sure everyone at Facebook has access to as much information as possible about every part of the company so they can make the best decisions and have the greatest impact.
Build Social Value
Once again, Facebook exists to make the world more open and connected, and not just to build a company. We expect everyone at Facebook to focus every day on how to build real value for the world in everything they do.
Thanks for taking the time to read this letter. We believe that we have an opportunity to have an important impact on the world and build a lasting company in the process. I look forward to building something great together.

LED bulb designs are constantly evolving, and they keep getting cheaper and more user-friendly. They’re energy-efficient, durable, and they contain no hazardous materials like mercury. But if you walked through your home today and replaced every single incandescent or fluorescent bulb with an LED, you might be disappointed with some of them. Consider the following factors to make sure you’re getting the most out of your LED light bulb upgrades.

Point The Light Where You Need It
Even when an array of light emitting diodes is packed into a “bulb” shaped casing, they still create a somewhat directional light source. This usually means that an LED light bulb will cast more light from the top end of the bulb than from the sides.

Manufacturers often refer to an LED bulb’s equivalent wattage (compared to an incandescent bulb) based on overall lumen output. Incandescent bulbs usually cast an evenly distributed glow, so a “60-watt replacement” LED bulb may not seem to pull its weight in a shaded table lamp. But in a recessed ceiling fixture, an LED bulb may actually cast even more light than its incandescent counterpart.
Energy Efficiency And Durability
One of the biggest advantages of an LED light bulb is its energy efficiency. Today’s best LED bulbs use roughly one seventh of the electricity consumed by an incandescent bulb, or half the power of a fluorescent. One of our favorites, the C. Crane GeoBulb 3 , is a 7-watt replacement for a 50-watt incandescent bulb or a 13-watt fluorescent.
Despite a relatively expensive initial purchase price, LED bulbs will pay for themselves over time by cutting your power bills. But only when they’re actually turned on – so they are especially well-suited for lights that are constantly in use. For example, a ceiling light that’s on all day long will take advantage of an LED’s efficiency better than an occasionally-used reading light.
LED bulbs last for a long time too – typically up to 50,000 hours (which translates to 12 hours a day, every day, for over a decade). This means fewer burned-out bulbs ending up in landfills, and added convenience too – you’ll rarely have to get your ladder out to change a bulb in a hard-to-reach.
