It’s estimated the growth rate will be 2.7% which leads to a market of 7,420 billion yen in total. The growth rate in 2009 was 5.4% declined, the situation will be reversed in 2010. Since Japan has revised the energy saving regulations, the demand of LED lighting products has been driven dramatically. It is expected that LED lighting market in Japan will be surged by 95.2% (2010 to 2009).
Yano said, globe-type LED light bulbs, as the major LED-based lighting product, are mainly used to replace traditional incandescent light bulbs. But entering 2010, LED lighting products which are claimed to replace fluoresent lamps are starting to appear on the market (fluorescents dominates approximately 70% of Japan’s current market of overall lighting). Moreover, some large local enterprises start to undertake LED light tube market which was undertaken mainly by oversea enterprises in the past. Therefore, the LED lighting market in Japan is forecasted to be further expanded in the future.

CFL vs. incandescent: Battle of the bulb
Compact fluorescent light bulbs are often mentioned as one of the easiest ways to shrink your power bill and your carbon footprint. They present the quintessential green-green situation: saving money and helping the environment. What's not to like?
There's the higher retail price - who wants to pay three bucks for a light bulb when it's sitting right next to ones that cost less than a dollar? But the CFL can last up to 10 times longer than incandescent bulbs, meaning you'd have to buy 10 of them during a single $3 CFL's lifespan. Each CFL saves about $30 during its tenure, according to the U.S. Energy Star program, and pays for itself in about six months.
One of the most potent threats to CFLs' superiority isn't their cost, but their contents. There's a small amount of toxic mercury in every one, which can be absorbed or inhaLed, potentially causing brain damage in adults, children and especially in fetuses. Fumble a CFL while changing a light, critics warn, and you unleash a poisonous fiend in your home. Throw it out and you're dumping mercury in landfills.
Those are both valid concerns, if sometimes a bit overblown. You should be careful when cleaning up a broken CFL, but don't go nuts - Snopes has debunked the myth that breaking one requires calling in an environmental cleanup crew. Keep kids and pets away, open the windows and resist the urge to vacuum, since that can kick up mercury vapor into the air; see the EPA's advice on cleaning up broken fluorescent lights for a complete guide. When they do eventually burn out, make sure to dispose of them properly.
Why do CFLs contain mercury?
Fluorescent and incandescent lights generally work the same way: They zap certain types of atoms with energy until their electrons freak out and release photons of light. Incandescent bulbs do this by shooting electricity into a thin metal filament surrounded by inert gas and encased in a glass shell. Metal normally emits invisible infrared light when heated like this, but get the atoms worked up enough and they'll produce a visible glow, too.
Metallic atoms are also the light source in fluorescent lamps, but they use vaporized mercury instead of a solid filament. The incoming electrical current is carried through a glass tube, straight or coiled, that's filled with mercury vapor and argon gas. The electrified mercury atoms begin vibrating and releasing invisible ultraviolet light, which in turn excites a fluorescent phosphor coating on the inside of the tube, finally producing the visible light.
(It's this jittery relationship, combined with a jumpy magnetic ballast providing electricity, that gives fluorescent lights their infamous flicker. Electronic ballasts don't have this problem.)
Mercury is a crucial part of how all fluorescent bulbs work, and replacing it is a daunting task. Still, manufacturers have cut back on how much they use - CFLs' mercury content dropped by at least 20 percent from 2007 to 2008. While the bulbs contained an average of 4 milligrams a few years ago, many now use as little as 0.4 mg. By comparison, mercury thermometers contain about 500 mg of mercury, and older nondigital thermostats contain about 3,000 mg.
Does mercury overshadow CFLs' benefits?
Fluorescent lights only release mercury when their glass breaks. Consider how often you shatter a light bulb while changing it, and divide that number by 10 - since a single CFL requires about that many fewer replacements - and that's your risk of mercury exposure.
An incandescent bulb doesn't contain mercury, but it still has a higher overall mercury footprint than a CFL, thanks to the coiled tube's renowned energy efficiency. Coal-fired power plants are humans' No. 1 source of mercury pollution, and energy-intensive incandescent bulbs require those plants to burn more coal than CFLs do. That extra coal burning releases far more mercury than even the combined amount inside a CFL and in the coal emissions needed to light it.
While most fluorescent lamps finish their lives without shattering, however, it's another story once they're thrown out. They can easy break in trash cans, Dumpsters or en route to a landfill. It's only a small amount of mercury, but it adds up as more and more people are buying them, and it also endangers sanitation workers who don't know they're carrying bags containing mercury vapor. All the more reason to read up on the EPA's guidelines for properly disposing of fluorescent lights.
Are incandescent bulbs burned out?
The main downside with traditional light bulbs is that they use only 10 percent of their energy to produce light, burning off the rest as heat. They've wasted 90 percent of the electricity people have been feeding them for the past 130 years - electricity that was mainly generated from coal and other fossil fuels. Congress put its foot down with the 2007 energy bill, introducing tougher efficiency rules that are expected to crush the market for incandescent bulbs beginning in 2012. Within a few years, the ever-cheaper CFL may dominate the Lighting market.
But don't count out Thomas Edison's original bright idea just yet. Despite the U.S. Department of Energy and EPA pushing CFLs, many people are still turned off by the light they emit, which is slightly bluer and more flickery than incandescents' warm, steady glow. To meet this lingering demand as well as the upcoming federal efficiency standards, several companies are scrambling to roll out a wave of next-generation incandescents. These bulbs keep their familiar shine and radiate less heat by reflecting some of the filament's light back inward. They're still more expensive than CFLs, but the price of such technology usually drops if it's successful.
Light(s) at the end of the tunnel
The future of artificial lighting is hazy, thanks to several recent technological and regulatory upheavals. Traditional light bulbs are almost certainly doomed once the new U.S. efficiency regulations take effect in 2012, leaving CFLs and improved incandescents to fill the void.
There's also a dark horse light bulb lurking in the shadows - light-emitting diodes, better-known as LEDs. These are already common in a variety of devices, ranging from the blinking red light on a video camera to the green power button on a computer. LEDs are more efficient, versatile and long-lasting than either incandescent or fluorescent lights, emitting light in a specific direction rather than radiating it outward indiscriminately, which wastes energy. They also absorb back what little heat they produce into an internal heat sink, leaving the LED itself cool to the touch.
While LEDs may seem like the obvious choice, they're still not entirely practical as a commercial substitute for incandescents or fluorescents. Several companies make bulbs that rely on diodes, but they aren't cheap. Odds are good the technology will eventually let LEDs overthrow their predecessors, but until then, the EPA and DOE are giving CFLs the green light.

Comparison of Several Typical Stuctures of LED T8 Tubes / T10 Tubes (Diagrams)
Probably, we’ve seen a lot of LED T8 Tubes in the market now or some of us may have carried out some projects that involved LED Tubes practically. So how about we take some time to look into some typical LED tubes by using some structure diagrams of LED tubes? I’d doubt that you have seen all of them before…
Take figure 01 and figure 03 for example, the typical structure of LED Tubes is: PC cover, LEDs, PCB, Heat sink and Driver(drivers do not show in these pictures).
PC cover: can be water-clear (transparent) and diffuse (milky).
LEDs: common LED type is SMD3528, some would be SMD5050, SMD3012 or SMD3014 etc.
Heat sink: typically aluminum but some may adopt PC (plastic) instead. Aluminum is good at rigidity and heat sinking while it significantly increases the weight of the tube.

LED Lights Replacement Case Study: City of Centennial, Colorado Saves More than $50,000 a Year
As part of a city-wide sustainability initiative, officials in Centennial, Colorado recently completed a project to upgrade each of the city's traffic and pedestrian countdown signals from traditional incandescent units to Dialight's high-efficiency, low-maintenance ITE-compliant Led traffic signals. The project, funded by the U.S. Department of Energy's Energy Efficiency and Conservation Block Grant Program (EECBG), not only improved visibility for drivers and pedestrians, but is expected to save the city $50,000-$60,000 a year in energy and maintenance costs.
Modern City, Progressive Planning
Appropriately named in honor of its citizens' September 2000 vote to incorporate, the City of Centennial is not only one of the youngest cities in the State of Colorado, but also the safest. With a vibrant community that blends the convenience of city living with the beauty of semi-rural neighborhoods, Centennial has been named Colorado's safest city for six years in a row. Home to nearly 110,000 residents, the city's backdrop against the picture-perfect Rocky Mountain skyline makes it one of the most beautiful in the Great American West.
In a progressive move intended to improve driver and pedestrian safety and reduce energy consumption and expenses, the city has recently completed a full replacement of its out-dated incandescent traffic signal balls, arrows and pedestrian indications with Dialight's ultra-energy efficient ITE-compliant traffic and pedestrian signals.
"Safety, reliability and overall brightness were significant concerns," said Craig Faessler, P.E., City Traffic / Transportation Engineer with the City of Centennial. "But, so were the energy consumption and maintenance costs. An upgrade to all-LED addressed all of these issues."
In addition to the fact that some of the faded lenses were at least 20 years old - as old as the signals themselves- the units consumed an exorbitant amount of energy and demanded nearly continuous maintenance with regular bulb changes to keep motorists and pedestrians safe. After a competitive bid process, Centennial chose Dialight units provided by Traffic Signal Controls, Inc., a Colorado-based Dialight distributor, for their efficiency and affordability.
Dramatic Energy Reduction = Significant Savings
In a two-phase project, fully funded by the EECBG program, the city replaced 1,288 red/yellow/green balls, 142 red/yellow/green arrows and 232 pedestrian countdown timers in Phase One, with the remaining 85 balls, 30 arrows and 1 pedestrian signal changed out in Phase Two.
Replacing the 116W incandescent signals and arrows with energy-sipping 8W LED units and the 59W incandescent pedestrian signals with 6W LED units is predicted to shave 572,000kWh off the city's electric bill, for a total energy savings of $36,000 per year. And, because the LED units will last at least five years-and likely even longer-Centennial expects to save $20,000 in annual maintenance costs by eliminating bulb changes, which also increases safety for signal technicians and motorists by eliminating unnecessary traffic control.
In another sustainability effort, Centennial is converting its school zone beacons to solar power.
"In addition to the energy efficiency, Dialight's products were the most affordable on the market to meet our needs, and the added bonus of the 5-year warranty sealed the deal," Faessler said.

And, because the LED units will last at least five years-and likely even longer-Centennial expects to save $20,000 in annual maintenance costs by eliminating bulb changes, which also increases safety for signal technicians and motorists by eliminating unnecessary traffic control.
In another sustainability effort, Centennial is converting its school zone beacons to solar power.
"In addition to the energy efficiency, Dialight's products were the most affordable on the market to meet our needs, and the added bonus of the 5-year warranty sealed the deal," Faessler said.

Bridgelux adds to RS LED array series, hits 8000 lm
Bridgelux adds to RS LED array series, hits 8000 lm
Bridgelux has expanded its RS LED Array family with new models that reach 5600 lm in warm white and 8000 lm in cool white, and targets market segments such as retail lighting and street lights.Bridgelux introduced the RS family of LED arrays a year ago, and is now adding products with greater lumen output for solid-state-lighting (SSL) applications. The company has enhanced versions of existing products that boost output 20% while reducing the cost per lumen by 30%, and the company introduced new products that offer light output in the 5600-to-8000-lm range.
The RS family targets applications that demand high-lumen sources. VP of Global Marketing Jason Posselt asserts that customer demand drove the company to create the RS family in which the company packages an array of emitters under a single lens. Target applications include retail-store lighting and LED street lights.
Bridgelux is offering the new members of the RS family in 2700K, 3000K, 4000K, and 5600K color temperatures. The LEDs have a CRI of 82, although the 2700K products can be optionally specified with a 90 CRI. The company is offering 3-step MacAdam ellipse binning.
The RS announcement covers both what are essentially enhancements to existing products as well as some new arrays. The company has boosted the light output of existing RS family members by 20% -- for instance taking what was a 3000-lm warm-white array to 3600 lm. According to Posselt, a combination of improvements in chip, epitaxy and packaging yielded the increased output and a 30% reduction in cost per lumen.
Larger chips
The brand new arrays that range from 5600 to 8000 lm leverage emitters manufacturers with a larger semiconductor area - larger chips. Bridgelux doesn't disclose the number of emitters used in its arrays because it sells the products as integrated single light sources.
Getting back to applications, Posselt discussed product requirements and design trends. He said, "The common approach is to gang together a bunch of emitters. For some applications that solution just doesn't work such as in retail lighting where light quality, lux level, and punch are really critical."
SSL is an ideal technology for retail stores, because lights are on constantly. LED efficiency leads to energy savings in such applications while long lifetimes reduce maintenance costs. But according to Posselt, the application requirements are tough to meet. He said, "We're not displacing incandescent sources, we're displacing 35W, 70W, and 100W ceramic metal halide sources that have a lot of punch."
LED street lights
While the RS family has already found success in retail lighting, the company believes that the new models will lead to success in street lights also. Posselt said, "We have a lot of customers developing solutions for street lighting. The challenge there is obviously developing optical solutions around this larger source size to create the required beam patterns."
Street lights that use small emitters utilized total internal reflection (TIR) lenses to form the beam pattern, but such lenses aren't practical with larger sources such as the Bridgelux arrays. See SSL luminaires must deliver reliable beam patterns in outdoor applications for more information on beam patterns.
According to Posselt, the company is working with partners to combine lens and reflector technology to form the required beam patterns but was unwilling to detail when that technology might come to market. But he added, "We believe there are real benefits in terms of the effective use of light, reducing the bill of materials, and reducing system cost." Posselt asserts that the RS family can replace a 70W - 150W HID source with a single packaged array.

Cree demonstrates 60W-equivalent LED retrofit lamp
Cree demonstrates 60W-equivalent LED retrofit lamp
LED-based A-lamp achieves Energy Star requirements for 60W replacement lamps, but Cree hasn't formalized plans to bring a product to market.Cree has developed an LED-based retrofit A-lamp that it claims is the first design that can meet Energy Star requirements for 60W-equivalent products. The company is having the performance of the design validated by a third-party testing lab, but has not decided how or when the technology will come to market.
The demonstration lamp outputs more than 800 lm with a color temperature of 2700K, CRI of 90 or better, and power consumption less than 10W. Cree expects third-party testing to validate lumen maintenance to L70 of 25,000 hours. Energy Star specifies 25,000 hours, and Vice President of Corporate Marketing Greg Merritt said, "We want to at least achieve that."
Cree has not provided details on the light-engine design, but Merritt stated that the performance is enabled by Cree's XLamp LEDs, TrueWhite Technology and patented remote-phosphor technology. TrueWhite Technology mixes light from yellow and red LEDS to offer warm white light.
Dual-dome remote phosphor
Cree hasn't previously announced remote phosphor technology. Merritt describes the retrofit bulb as a dual-dome design with the remote phosphor deployed in the inner dome.
The design uses a passive cooling scheme enabled in part by the increasing efficiency of LEDs according to Merritt. In the nearby photo you can see the cooling fins. Merritt said, "It looks more like a traditional bulb" when asked about more radical designs such as Philips' products that leveraged air channels between portions of the lens. Merritt asserts that consumers have voiced a strong preference for replacement lamps that look like traditional bulbs.
Merritt made the point repeatedly that the development of the retrofit lamp was not simply an engineering exercise. He also acknowledged that Cree hasn't decided how to proceed with the product. Merritt said, "We haven't decided if, how, or when we will bring it to market."
Merritt did hint at a strategy saying, "We have a strong track record of making our innovations available to our customers." When asked if that meant customers of Cree LED components, Merritt added, "All of our customers, customers who want to make similar products." That comment implies that the demonstration is essentially a reference design.
Cree CEO Chuck Swoboda made similar comments about Cree's lighting business in the keynote speech he delivered at a recent LED developers' conference presented by Cree and Arrow (see links at the right for full details). Swoboda had indicated that Cree's system business was largely dedicated to system development that can help customers solve problems thereby ramping component sales.
At the launch of the A-Lamp demonstration, Swoboda said, "We are committed to leading the market and showing the industry what's possible with recent innovations in our LED products and technology. We are excited to show the world what it should expect in an LED light bulb and enable our customers' products with these innovations."
Low cost and high performance
Both Swoboda and Merritt emphasized that the A-Lamp design was designed to be cost-effective and to yield quality light. "In the race to commercialize low-cost, energy-efficient LED bulbs, the industry has forgotten that LED lighting is supposed to look as good as the technology it is replacing," said Swoboda. "This is the first no compromise replacement for a 60 watt incandescent bulb."
When asked about the goals of the project, Merritt said, "We wanted to demonstrate that you could do this with a product that was designed for mass production at an attractive market price." When reminded that the product price was still an unknown, Merritt added, "Obviously you have to take me at my word for this because I'm not telling you how much it costs."
Given the specifications of the retrofit lamp, we wondered if the design might be entered in the US . The DOE has temporarily suspended the PAR 38 portion of the competition while the Philips lamp remains the only entry in the A-Lamp competition. According to Merritt, however, the Cree design was optimized for cost. It doesn't produce the 900 lm required for the L-Prize.
The Cree lamp is designed to meet all of the elements of Energy Star for retrofit lamps. That includes the requirement for uniform light distribution below the equator of the bulb according to Merritt. Merritt asserted that no 60W-equivalent SSL product has complied with Energy Star requirements to date.
Cree chose the anniversary of Edison's patent issue date for the A-Lamp as the date to launch the retrofit demonstration. It was 131 years ago that the patent office recognized what became known as the Edison socket.

LED Grow Lights
Description
LED Grow Lights (Plant Growth LED Lights) is one type of grow lights that adopts LEDs (light emmitting diode) as light source. The basic principle is to use man-made light instead of natural sunlight, thus providing favorable environment for the plants for their growth and development. |
| LED Grow Lights |
LED Grow Lights can be used for plant growth in several ways:
- 1. To provide all the light plants need to grow.
- 2. To provide specific (wavelenth) light that plants need to grow. Meanwhile, do not provide specific (wavelenth) light that plants do not need for growth. This is the reason why LED Grow Lights are much more efficint than other grow lights.
- 3. To supplement sunlight, especially in winter months when daylight hours are short.
- 4. To increase the length of the "day" in order to trigger specific growth and flowering.
Features
- Energy efficient and environment-friendly
- Only 20-30% electricity of HID grow lights
- Long lifespan
- Minimal heat
- Versatile
- 60W,90W,120W,300W,600W
Note: In order to provide the best development enviroment for the plants, light source needed by each plant is different (different wavelength and intensity). Should you need us to provide relevant information for reference, please feel free to contact us to discuss.
