To avert disputes over chip intellectual property

The company directly mounts packaged devices on an aluminum substrate can help reduce thermal resistance. Tsao notes the technology brings total junction temperature on their LED module to under 80 degrees centigrade.To avert disputes over chip intellectual property, the company builds Epistar Inc.’s chips into emitters for domestic sales and led high bay light chips into products for exports. Tsao says that his company’s R&D team brings together considerable talent in thermal-dissipation and optoelectronics. They can provide lighting manufacturers with tailor-made solutions. Besides, they have developed emitters in cooperation with end-product manufacturers and retailers. Major applications for the company’s emitters include MR16, sunken lamps, down lights, wash wall lamps, and streetlights.

Tsao points out that high cost remains the major hurdle keeping LED from becoming a mainstream illumination source today. Comparing a 13W LED lamp with a compact fluorescent lamp in same power specification, Liu notes the LED lamp is priced eight times above the fluorescent lamp. However, he estimates Taiwan LED-lighting manufacturers can pare that multiple to just three- to five-fold in two years by trimming production costs.

NeoBulb Light Engine, a high-power LED lighting module comprising an emitter and a thermal module, has made a splash since it was debuted in 2005. The attention owes largely to its system-in-a-packaging technology and heat-pipe thermal module. According to the company’s president and led high bay light executive officer, Jeffery Chen, the whole module’s junction temperature is less than 60 degrees centigrade and ambient temperature maintains at about 25 degrees.The company has registered over 50 patents for its outstanding packaging and thermal technologies.

This closes a gap with the very large goniometers

In addition, Shih said that the requirement will be more flexible than the existing ceiling of 10% stake owned by Chinese investors in existing enterprises and stricter than the 50% ceiling in new joint ventures.The third-wave mainland Chinese investments have been approved by Taiwan Executive Yuan (the Cabinet) and are scheduled to take effect by the end of March. The LGS 250 was developed specifically for the analysis of angle-dependent spatial radiation properties from small to medium-sized SSL luminaires, lamps and LED modules. This closes a gap with the very large goniometers. The horizontal alignment of the Type C coordinate system facilitates a particularly convenient and compact test setup for the system. Measurements can be taken in a range of +/- 160° in the forward direction of the test specimen which may have a maximum diameter of up to 480 mm and a maximum weight of 8 kg. Combined with a spectroradiometer from Instrument Systems, all spectral quantities such as color coord...

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...
