when five LED modules were needed for the headlight

It is know that LED light bulbs are to be treated for heat dissipation and to have uniform lighting. Solution from LIQUIDLEDS is to use “liquid” in LIQUIDLEDS LED light bulbs.  With the technology of Liquid Immersed Thermal Management Solution, the liquid not only acts as an excellent medium for heat dissipation of light bulbs but also helps reshaping the luminosity in the beam angle as well as uniform lighting of the light bulbs.LED lights are designed for stylish architectural led high bay light or for landscape lighting, as well as spot lighting points of attraction or for public lighting as needed. The LED light unit has a mounting bracket so it can be secured with bolts anywhere it is needed.The white LED modules used in the two units were manufactured by Nichia Kagaku Kogyo KK and consist of four elements. The modules were also used in the LED headlight of the Toyota’s "RX450h", which was released in April 2009, according to Koito Seisakusho.

Seisakusho used LED headlights for the first time in the world on Toyota's "Lexus LS600h" in May 2007, when five LED modules were needed for the headlight. Now, due to the improved LED efficiency, the number of LED modules needed for the LED headlight for the new Prius has been reduced to three.The two headlights mounted on the new Prius are 66W, slightly more than 30% lower compared with 100W of the headlights of the LS600h, according to Koito Seisakusho.In recent months, Samsung and other LCD TV manufacturers have actively promoted LED-backlit models and hence thirsted for blue LED chips. At present, Samsung has booked large portions of Epistar and Formosa Epitaxy`s capacity to secure supply of the components, which has driven the two Taiwanese LED chipmakers to boost outputs.

Epistar says it plans to outsource some capacity as well as introduce MOCVD (metal organic chemical vapor deposition) to loosen its production lines, and will expand its in-house downstream production capacity, in an effort to boost its existing output of 1.1 million LED chips to 1.4 million units by the end of this year.Formosa Epitaxy has invested a total of US$4.5 million in capacity expansion this year, after the plan to raise capitalization of its plant in Shandong, northern China by US$3 million recently. The firm will expand its laser engraving lines before setting up new epitaxial wafer production lines.

LED recessed downlighting options for general lighting in commercial

Cooper Lighting, a division of Cooper Industries plc (NYSE: CBE), has expanded its Halo LED H7 Collection offering additional choices in LED color temperatures and higher lumen options. The 6” LED downlight product line expansion–from the original Halo LED 600 Series–now includes the Halo LED 900 Series and Halo LED 1200 Series, offering a wide and versatile selection of energy-efficient LED recessed downlighting options for general lighting in commercial, retail, institutional and residential applications. Designed for new construction projects or to retrofit existing 6” nominal compatible housings (with an Edison screw base adapter included with the module), the Halo LED H7 Collection features excellent color rendering (80 CRI) and offers the industry’s widest selection of color temperatures (2700K, 3000K, 3500K and 4000K). The superior optical design yields productive beam lumens providing smooth, even illumination, excellent cutoff and extremely low glare. Consuming less than 15W, ...

Semiconductor lighting industry in Shenzhen develops rapidly in recent years

Orion’s LED fixture, designed to perform at temperatures as low as -20 degrees Fahrenheit, has been retrofitted in more than 3 million square feet of freezer and cold-storage space in facilities across the nation in the past several months. Companies with Orion LED technology in their facilities include US Foods, Sysco, Americold, and Save-A-Lot. The three approved Orion LED fixture models vary based on application-specific lens configuration. Orion’s LED fixtures are designed to replace traditional high intensity discharge and T8 and T5 fluorescent fixtures. Orion’s LED fixtures use 123 watts compared to 400-watt HIDs and 298-watt fluorescents. According to its Web site, the DLC is a collaboration of utility companies and regional energy efficiency organizations committed to raising awareness of the benefits of efficient lighting in commercial buildings. In order to be included on the DLC’s QPL, a product must meet or exceed specific industry standards. QPL inclusion is required for c...

Entertainment applications will adopt the new LEDs

The number and breadth of applications that require amber LEDs is tremendous,” said Frank Harder, VP of Product Marketing at Philips Lumileds. “Markets including automotive, entertainment, roadway, signaling, and many others use amber LEDs. With better efficiency and more light output, LUXEON Rebel PC amber makes it that much easier to reduce energy consumption with an environmentally friendly product.lamps to LEDs because they didn’t produce enough light and couldn’t operate effectively at higher temperatures. With the advances provided by LUXEON Rebel PC Amber, yellow traffic signals will be converted, warning lights and beacons on vehicles and obstructions will switch and entertainment applications will adopt the new LEDs. numbers of amber LEDs. With LUXEON Rebel PC Amber, manufacturers will be able to use fewer LEDs and lower other component costs because of the improved light output and particularly the stable color over temperature, something that has been problematic for many ...
