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 coordinates, color temperature, and color rendering index can be determined as a function of angle. C-plane measurements can also be carried out very quickly “on the fly” using the Optronik DSP Photometer. The LGS 250 is supplied in two versions as a goniometer with a stable base and integrated LGS Controller, and as a benchtop version with separate 19” rack for the LGS Controller.

The SpecWin Pro software supplied permits convenient and efficient analysis of the measured data with a range of display options. The measured data obtained can also be exported in IES and EULUMDAT format. The LGS 250 is also compliant with all the relevant specifications in conformity with CIE, DIN and IES standards.

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 ...
