This release in:

MALVERN, Pa. — June 17, 2010 —Vishay Intertechnology, Inc. (NYSE: VSH) is broadening its optoelectronics portfolio with new LED light panels for streetlight and industrial overhead lighting applications that double as the core of a development kit that gives designers everything they need to get up to speed designing with Vishay’s solid-state lighting solutions.

In addition to the 4 x 6 LED panel, the kit includes reflectors and a driver module, providing the basic tools designers need to avoid development delays and focus on getting lighting products to market quickly, while adopting energy-efficient, environmentally friendly, long-lifetime LED lighting technology.

Two panel options are available. The VLSL30 panel features cool white LEDs with a temperature range of 5000 K to 7000 K and a luminous flux of 2160 lumens. The VLSL31 panel features neutral white LEDs with a temperature range from 3800 K to 5000K and a luminous flux of 1900 lumens.

The VLSL30 and VLSL31 light panels consists of 4 strings of 6 LEDs mounted on a single-sided, single-layer, copper-based PCB. The copper base quickly conducts heat away from the LEDs, extending their operating performance and life, while the shiny white surface provides a small degree of reflectivity of incident light. The panel measures 135 mm by 121 mm.

The optional VLSL3-DU driver features output power up to 56 W and offers 8 boost-regulated constant-current channels, each with 6 LEDs. The driver is designed to provide power to two light panels. It features reverse polarity protection, closed-loop regulated current control, and 12-VDC input with undervoltage and overvoltage control and load dump protection. Each panel can be programmed to respond to input from an ambient light sensor. Based on the ambient light level, the driver will adjust the pulse width modulation to one of four settings: 100 %, 75 %, 50 %, and 25 %. It also features an RS232 input for custom programming of the controller.

Aluminum alloy reflectors are also available to control the pattern of illumination. Without reflectors, the viewing angle of the VLSL30 and VLSL31 power modules or light panels is 120 in all directions. This viewing angle can be tightened in one direction to 55 with the use of the VLSL-REFL01 reflectors.

The panels, driver, and reflectors are sold separately or as a kit to simplify development. The VSL30-LDK features cool white LEDs while the VSL31-LDK features neutral white LEDs. Each kit comes with 1 light panel, 5 reflectors, and 1 driver.
