LED Panels Generate Up To 2,160 Lumens

Suiting up for streetlight and industrial lighting apps, the VLSLxx family of light panels employs 24 LEDs to deliver a luminous flux up to 2,160 lumens. The VLSL30 panel features cool white LEDs with a temperature range of 5,000K to 7,000K and a luminous flux of 2,160 lumens while the VLSL31 panel features neutral white LEDs with a temperature range from 3,800K to 5,000K and a luminous flux of 1,900 lumens. Both panels use four strings of six LEDs on a single-sided, single-layer copper-based PCB and measure 135 mm x 121 mm. An optional driver, the VLSL3-DU, enables an output power up to 56W and offers eight boost-regulated constant-current channels, each with six LEDs. The driver provides power for two light panels and features reverse polarity protection, closed-loop regulated current control, and a 12-Vdc input with under-voltage and over-voltage control and load-dump protection. The panels also come in development kits that provide a LED panel, VLSL-REFL01 reflectors, and a VLSL3-DU driver module. Separate single-unit pricing for the VLSL30 or VLSL31 light panels is $100 each, VLSL-REFL01 reflector is $10 each, and the VLSL3-DU driver is $125 each. Offered together as a kit, pricing is $222 for the VLSL30-LDK or VLSL31-LDK. VISHAY INTERTECHNOLOGY, INC., Malvern, PA. (619) 336-0860.
