How Much Do You Know about the “Three Mistakes” When Buying LED Lights

At present, LED illumination lamps and lanterns are more and more popular and pervasive with the explosive growth of LED industry output value. Moreover, people have fallen in love with spark LED lights and can’t leave them in daily life and work. 
However, because of poor LED technology standard, excess production capacity and cutthroat competition between enterprises, many of LED lighting products aren’t good in quality. Also, people know no much knowledge about LED lights when choosing them.

Keep it in mind with the advices of the following three mistakes:

Mistake One: Have excessive expectations to actual service life of LED lights
Generally, LED manufacturer anticipate LED service time up to 100,000 hours MTBF (Mean time between failures-standard that traditional lamps manufacturers use for measuring lifespans of light source). But the LED luminous flux lumens also decrease over time like more all of basic light source. Therefore MTBF isn’t the unique considering factor to confirm the service life of LED even through the time of LED lighting is very long. The attenuation of LED lumens is affected by some environmental conditions, such as temperature, humidity and ventilation, also including control, thermal management, current level and other electric design factors.
So with the light source, brightness of light has a gradually attenuation and dimming process and this process is called lumen decrease. 
When you buy LED lamps and lanterns, what you focus on is the speed of lumen decrease but not service life. Do not have excessive expectations to actual useful life.

Mistake Two: Count actual beam angle as effective angle
The beam angle of LED includes effective angle and actual beam angle. The included angle between direction of which luminous intensity values are half of axial intensity values and direction of lighting optic axis is named effective angle. The viewing angle of double half-value angle is named actual beam angle. The angle which is beyond half of axial direction intensity isn’t calculated in effective angle because of too weak light ray.
When you buy LED products or calculate the amount of LED lighting products in project, you should focus on the actual beam angle and effective angle is only looked as reference.

Mistake Three: The more power, the higher brightness
The brightness of LED is measured with luminous intensity that is a photometric quantity measured in lumens per steradian (lm/sr), or candela (cd/mcd). Generally, light source can emit different luminous flux to different directions and the visible light radiation intensity which emits from unit solid angle in specific direction is light intensity or axial direction brightness for short.
In electric power, the faster current is, the higher electric power is. However, about LED power, it is not that the more power is, the higher brightness is. 
For example, one lamp in two modes from Spark, first mode-axial direction brightness 1200mcd, current 40ma, power 0.4w; second mode-axial direction brightness 1200mcd, current 18ma, power 0.24w. From this figures comparison, we can know that the power is different in same brightness. In other words, the saying that the more power is, the higher brightness is is wrong.
When we choose spark LED lamps and lanterns, we should pay attention to axial direction brightness or luminous intensity not power.

Lighting Tips for Surviving the End of Daylight Savings

The end of daylight savings arrives at 2 a.m. on November 2, 2014, throughout most of the United States and Canada. For many, it's more than just setting the clock back an hour. It can come as a shock to leave work at the usual time, only to return home after the sun has set. Interior and exterior lighting is a great way to offset this sudden shift in light and prepare for the longer evenings to come.

For starters, a comprehensive landscape lighting plan brightens the yard during the winter months, when daylight hours are limited. LEDGROSSISTE bulbs offer long lifetime , allow significant energy saving and diffuse a beautiful white , warmwhite , simple, and elegant light. They can be perfectly replace incandescent bulbs. The LED bulb can be used in homes , shopping malls, offices, hotels, showrooms, conference rooms ,and other places. Mainly used for crystal lamps, wall lamps, suspensions and other atmospheric lighting rendering.

There are a number of other fuss-free ways to light the home's exterior and eliminate the worry of running the electrical bill up too much. For instance, useing an internal light sensor to turn the unit off and on with the rising and falling of the sun. For an even more specific option, motion sensor security lights turn on only when they sense movement nearby. Motion sensor lights are best-suited for deterring would-be burglars and illuminating high-traffic locations such as garages and back doors.

Indoors, similar technology makes it easy to keep the lights on during the winter months. Motion sensors can also be installed to trigger lights each time a person enters the room. To avoid returning home to a dark house, consumers can use timers for table and floor lamps. Installed directly into the outlet, these timers can be easily set to turn lamps on and off at regular intervals. And new wireless remotes make it easier than ever to operate lights throughout the home. Able to operate up to three outlets at once, the latest remote control designs allow a person to control lamps and other appliances with the single touch from a handheld remote.

Despite the increased convenience of many new lighting products, longer evenings still require homeowners to keep lights on longer. Luckily LED lighting – which is up to 10x times as energy-efficient as standard incandescent lighting – can make up for those extra hours on the electrical bill. And it looks great too.The quality of LED light has increased dramatically over the years. "For the 'warm' look that people used to associate with standard bulbs, consumers should look for LEDs with low color temperatures in the 2700K-3000K range." Higher color temperatures provide a clear and "cool" white light that's ideal for reading and other tasks around the house.

From safety and security in the yard to fresh new style indoors, LED and other new technologies offer easy and energy-efficient ways to keep the home bright all winter long. As a reminder, don't forget to set clocks back one hour before going to bed on Saturday, November 1st.

Bright Lights, Big Profits: LED technology taking the world by storm

Ed Ebrahimian loves to stare out of the plane window on night flights home to Los Angeles. Next time you fly into LA late, take a good look and see why. Five years ago, a bright orange blanket of light used to saturate the city and stain the air above. Today, it’s a metropolis aglow with tens of thousands of cool silvery pinpoint lights. The grid is clearer. The skies are blacker.

“The lights look like candles now and they aren’t glaring at all,” Ebrahimian gushes. “The sky glow is the most amazing thing I’ve seen in my life.”

Ebrahimian has good reason to be enthused. As director of LA’s Bureau of Street Lighting, he’s overseeing one of the largest relighting projects in the world, spending $57 million to retrofit the city’s 215,000 lights, which come in more than 400 styles. The money has gotten him only to lamp post number 155,000 after five years. Replacing the remaining 60,000 will cost $50 million more.

Los Angeles is a dramatic front in an important and overlooked battle facing the rapidly urbanising world: The struggle between light and dark. Cities and businesses want more light everywhere for commercial and safety reasons, but our decades-long saturation bombing of the darkness is blowing holes in electricity budgets, confusing and killing wildlife, and completely erasing our view of the stars, the inspiration for millennia of scientists, poets and explorers. “What was once a most common human experience has become most rare,” writes Paul Bogard, author of The End of Night, a book that assails the world’s unchecked light pollution.

The technology at the centre of the shift is the LED, or light-emitting diode. LEDs are a break from the history of illumination. As solid-state semiconductors, they’re more akin to the processor in your smartphone than the lamp overhead. Los Angeles, New York, Chicago, Shanghai, Copenhagen and scores of other cities around the world are deploying LEDs to solve most, if not all, of the problems created by inefficient traditional lamps.

LEDs cost three to four times more than traditional high-pressure street lamps, but they last three to four times longer and produce two to three times more light per watt, delivering anywhere from 30-70 percent in annual electricity savings. Because they are digital chips, they will only get cheaper as the efficiencies of Moore’s Law roll on. And as electronic components, they’re also far more programmable and connect more efficiently with radio and sensor chips to create citywide wireless networks to monitor crime, power outages and water main breaks and coordinate disaster relief.

The business opportunity in the great LED retrofit is enormous. Of the 140 million street lights installed worldwide last year, only 19 million were LEDs, according to IHS Tech- nology. By 2020, LEDs are expected to account for 100 million of the installed base of 155 million street  lights. Annual sales of LED street lights will jump from $4.3 billion to $10.2 billion in the same time period. Boston, Seattle and New York City are all undertaking big retrofits. New York’s $76 million project will be the largest in the US: Replacing 250,000 lights by 2017. City officials expect to reap $14 million in energy and maintenance spending per year.

The biggest players in street lighting—Osram, Royal Philips, Acuity Brands and Panasonic—are racing to implement new business models. Manufacturers used to count on selling replacement bulbs and components every four years, but LED lights come with a 10-year warranty, though many will last 15 to 20 years. Several manufacturers are focusing on selling software to control and monitor LED networks from a central command centre or smartphones. Philips launched its CityTouch management software in 2011 to monitor the energy consumption of each light, spot failed lights and dim or brighten each. The company now collects an undisclosed amount of annual service fees from 260 lighting-project owners in 31 countries. Manufacturers and utilities are introducing financing schemes in which they assume the upfront installation costs and take a long-term share of the energy savings from the city.

“The light industry is changing, so we are looking at what our next step is,” says Martin Oerder, head of Global Outdoor Systems at Philips Lighting in the Netherlands.

Cheap Energy-saving LED Street Lights

This month three men shared the Nobel prize in physics for their invention of blue light-emitting diodes (LEDs). In its citation, the Nobel committee declared: "Incandescent light bulbs lit the 20th century; the 21st century will be lit by LED lamps."

It's already happening. Not just in our houses, but increasingly outside too. LED street lights, which are being fitted in cities in many countries, seem like a good idea, because of their energy efficiency.

But then I came home to Newton, Massachusetts, from a holiday to find the ugly reality glaring at me. Scattered light washed out all but two stars in the night sky, and harsh white light cast stark shadows on my porch. I was stunned and dismayed. Why should energy-efficient lighting make the world look garishly bluish-white and bright?

I saw no indication of this when I installed LED bulbs indoors. Manufacturers sought to please the customer's eye, adding phosphors that converted most of the blue light into yellow and red to give a glow similar to the warm white of an incandescent bulb.

But outdoors, the US Department of Energy is pushing LEDs only as cost-effective lower energy lighting. Its municipal street-lighting consortium web page focuses on savings in dollars and lighting intensity in foot-candles (visible light per unit area) not colour ambience. The bluer the output, the greater the intensity perceived by the eye, so that's what we get. LEDs can also spread light more evenly than older bulbs, because they can contain many small light emitters pointing in different directions.

But those benefits have costs. One is a blue-rich colour mix like moonlight or bright daylight, which many people find unpleasant at night. Glare is another, because "each little LED [in a street light] is one-sixth as bright as the sun", says James Benya, a lighting designer in Davis, California, where LEDs have provoked protest. The tiny LEDs on the edges of a lamp point outward to spread light across the street, creating glare for pedestrians and drivers.

That glare also shines into homes and gardens. Light trespass is a key factor behind protests in cities from Davis to Cambridge, Massachusetts, and in UK towns and cities. Studies of the impact of LED street lights are under way in many other countries, including Germany and the Netherlands. Pilots have also warned that LEDs being tested for runways produce dangerous glare.

A further concern is that LEDs will worsen excess artificial light at night. Air scatters blue light more than other colours, making the night sky so bright itwashes out the stars. Blue light can also suppress melatonin production in humans and animals, affecting sleep and behaviour. The International Dark-Sky Association recommends that outdoor lights should use the same reduced-blue LEDs as indoors.

Of course LEDs have advantages. Unlike high-pressure sodium lamps, they can be instantly turned on and off or dimmed. Moreover, our night vision is more sensitive to blue light than to red, so bluish LEDs allow the same visibility with lower illumination levels than redder lights. But most cities use LEDs at the brighter illumination recommended for the bulbs they replace, wasting energy and increasing the negative impacts.

The challenge is to balance the trade-offs between energy efficiency and environmental impact before the roll-out of LEDs outdoors gets any bigger. In my city, officials have offered to adjust the ones near my house to reduce light shining in the windows, but if they had waited for better bulbs it would have saved time, money and aggravation.

Un choix clair --- ampoules LED de Ledgrossiste.fr

Nous arrivons à la date à laquelle les horloges " retomber " à l'heure normale de l'Est. Avec l' heure plus tôt pour la nuit , les lumières s'allument plus tôt et plus long terme également . Ne serait- il pas merveilleux d' économiser de l'argent et de l'électricité sur tout ce que l'éclairage ?

Eh bien maintenant, il est facile d'obtenir un éclairage lumineux , faible consommation d'énergie avec des ampoules LED qui sont plus durables tout en utilisant moins d'électricité que les ampoules incandescentes ou ampoules fluorescentes compactes (CFL) . En fait , les derniers chiffres de l'Energy Information Administration des États-Unis montrent que, en 2012 , l'éclairage résidentiel a consommé environ 186 milliards de kWh , soit environ 14 % de la consommation résidentielle d'électricité . LEDGROSSISTE note que si chaque foyer remplaçait une seule ampoule avec notre ampoule qualifié , cela permettrait d'économiser assez d'énergie pour allumer 2 millions de foyers pendant une année entière .

A Bright Choice ---LED Bulbs of Ledgrossiste.fr

We’re coming up to the date when the clocks "fall back" to Eastern Standard Time. With the earlier hour for nightfall, the lights come on earlier and run longer, too. Wouldn’t it be great to save some money and electricity on all that lighting?

Well now it’s easy to get bright, low-energy lighting with LED bulbs that are longer-lasting while using less electricity than incandescent or compact fluorescent lightbulbs (CFL). In fact, the latest numbers from the U.S. Energy Information Administration show that in 2012, residential lighting consumed about 186 billion kWh or about 14% of all residential electricity consumption. LEDGROSSISTE notes that if every household replaced just one light bulb with our qualified bulb, it would save enough energy to light 2 million homes for a whole year.

Today we have wonderful technology in the new LED bulbs. The LED is the lowest in wattage and annual kWh when compared to a CFL and an incandescent of the same brightness (lumens).

Such as the a 6W LED lamp of LEDGROSSISTE, it offer long lifetime , allow significant energy saving and diffuse a beautiful white , warmwhite , simple, and elegant light. They can be perfectly replace incandescent bulbs. The LED bulb can be used in homes , shopping malls, offices, hotels, showrooms, conference rooms ,and other places. Mainly used for crystal lamps, wall lamps, suspensions and other atmospheric lighting rendering.And the bottom line is that LEDGROSSISTE LED lighting can deliver outstanding energy efficiency (since LED bulbs are not all the same when it comes to performance, ENERGY STAR tests and provides a logo for bulbs that perform most effectively).

Beyond saving energy, LED bulbs can save money over time because they last so long. One of the things LEDGROSSISTE does is test to see how long certified bulbs will last, and you can expect a certified LED bulb to last 20 years. CFLs can last up to 10 years, while you would need 25 incandescent bulbs to light your way through 20 years.

Besides the longevity of the LED bulbs, anywhere from 25,000 to 50,000 hours, they are instantly on. If you are using CFLs you may be accustomed to waiting for the lights to come to full brightness--no more wait with an LED. LEDs are durable, not sensitive to weather, no hazardous material, aren’t affected by frequent cycling on/off, have the lowest heat output, and are available in dimmable versions.

With newer technology, the diodes are 'clustered' to provide more light, and mounted within diffuser lenses, which spread the light across a wider area. Advancements in manufacturing technology have driven the prices down to a level where LED bulbs are more cost-effective than CFLs or incandescent bulbs. This trend is continuing, with LED bulbs being designed for more applications while the prices are going down.

Nobel Prize in Physics Awarded for Invention of Efficient, useful blue-light LED

Three researchers received the 2014 Nobel Prize in physics on Tuesday for the invention of this blue light-emitting diode (LED), a technology now used in high-speed networking, data storage, smartphones, water purification, and efficient home illumination.

The winners are Isamu Akasaki, a Japanese citizen and professor at Meijo University and Nagoya University; Hiroshi Amano, a Japanese citizen and professor at Nagoya University; and Shuji Nakamura, an American citizen and professor at the University of California in Santa Barbara.

The key advantage of their invention 20 years ago is the production of light with far less waste of electrical energy than with preceding technologies like incandescent and fluorescent lights, the Royal Swedish Academy of Sciences said in awarding the prize.

"A quarter of energy consumption goes to illumination," said Per Delsing, a physics professor at the Chalmers University of Technology in Sweden, during a press conference announcing the award. As a result, any increase in efficiency and consequent saving of energy "is really going to have a big impact on modern civilization," he said.

Nobel Prizes in physics often go to fundamental discoveries such as the Higgs Boson. But when the committee makes an award for an invention, "we really emphasize the usefulness of the invention," said Anne L'Huillier, an atomic physics professor at Lund University in Sweden, also speaking at the press conference. And the blue LED is nothing if not useful.

Recent Nobel prizes have been awarded for concepts that are very far from day-to-day human experiences -- giant magnetoresistance, Bose-Einstein condensates, superconductors and superfluids, and the accelerating expansion of the universe, for example. The blue LED -- something you can buy at the local home-improvement store -- seems downright mundane by comparison.

But it's anything but ordinary, said H. Frederick Dylla, chief executive officer of the American Institute of Physics, who called the work a "tour de force" because it required a combination of materials science, physics, and chemistry. Indeed, the invention of the blue LED was on a short list of his institute's candidates for the prize, he said.

"It's a very expensive technology requiring atomic-layer epitaxy, where layers are put down atomic layer by atomic layer at a very high vacuum," Dylla said. It's vastly more complicated than incandescent lights, he added. "Compare that to drawing tungsten wire and putting it into a blob of glass and blowing out the air with some argon, and you have a light bulb for a few cents."

Three colors of LED

The white light from the sun can be reproduced artificially by blending three colors of light: red, green, and blue. LEDs are very efficient at converting electrical energy into visible light, but blue LEDs proved much harder to engineer than red and green ones. It took more than a quarter century after red LEDs were invented in the early 1960s before semiconductor materials and fabrication techniques grew sophisticated enough to enable blue LEDs in the mid-1990s.

White LEDs work either by packaging trios of red, green, and blue LEDs or by using just blue LEDs whose light also excites phosphors that emit green and red.

Now those white LEDs are spreading rapidly across the globe, led by lighting applications.

Incandescent lights -- the traditional Thomas Edison-era light bulb -- work by heating up a filament until it glows. That approach produces light, but most of the energy is wasted as heat.

Fluorescent bulbs are more than four times more efficient, a big step forward. But LEDs are nearly twenty times as efficient as incandescent bulbs, and they aren't saddled with the risky mercury-related health risks of fluorescent bulbs. As an added bonus, LED lights last longer, too.

White LEDs are now used widely in streetlights, traffic lights, flashlights, vehicle headlights, and as costs come down, home and office lights. They're also a major force in electronics, providing the light in screens in laptops, phones, tablets, and TVs.
