LED system can also be extended given the elimination of capacitors

Specifically designed for high-power LEDs (for example, in the 0.5W, 1W or 3W range), the BCR 450 in combination with an external transistor offers precise current control, thermal protection, and over-voltage and over-current protection functions. By simply changing the external transistor, manufacturers of LED lighting have the flexibility to adapt output currents from 100mA to above 1A.
The new driver IC produces no electromagnetic radiation, thus is ideal for applications sensitive against EMI, such as lighting in transportation vehicles including buses, ships, trains and aircrafts, as well as medical applications with communication bus systems. Except the general lighting systems, it can also be applied in architectural and accent lighting, advertising, strobe lights for emergency vehicles, hazard lights and road safety lights.

Due to a small PCB space, the BCR 450 features an application circuit which is free of inductors, capacitors and free-wheeling diode. The elimination of the electrolytic capacitors ensures a longer lifetime than switch-mode driver solutions. The lifetime of the LED system can also be extended given the elimination of capacitors.


With its output current precision varying only ±10 percent over the entire operating temperature range, the BCR 450 fulfills the homogenous light output requirement which is of crucial importance in the whole LED chain especially in architectural lighting market.

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...

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...
