MALVERN, USA: Vishay Intertechnology Inc. announced two metal-core-based, cold white LED power modules, each assembled with 12, 24, or 36 high-brightness LEDs.
The new VLSL40xxA is designed for flexible use by utilizing optional special reflectors to adjust the modules' emission characteristics. The VLSL50xxA features a clear silicone lens for a butterfly-shaped radiation characteristic.
Optimized for illumination in streetlights, internal building lighting, tunnel lights, and general lighting applications, the VLSL40xxA and VLSL50xxA offer a color temperature range of 5000 K to 7000 K.
Both devices feature a shiny white surface and a metal-core, single-side PCB with a Cu thickness of less than 0.75 microns. Each module includes a conductive top layer with a minimum Cu of 18 microns and a 63 micron prepreg 1080 FR4 type isolation layer.
The VLSL40xxA is available with the VLSL-REFL01 reflector, which is composed of an Al-alloy material with a non-high-polished surface. By using different reflector combinations, the emission in one direction can be adjusted in a typical range of 120 to 55 degrees. The clear silicone lens of the VLSL50xxA allows for a 35 degree vertical and 60 degree horizontal angle of half intensity.
The VLSL40xxA and VLSL50xxA are based on InGaN technology and provide a maximum current of 700 mA. The LED modules feature standard solder mask material, and they offer luminous flux and color binning. The devices provide ESD withstand voltage up to 2 kV in accordance with JESD22-A114-B and comply with ROHS 2002/95/EC.
Samples and production quantities of the LED power modules are available now, with lead times of eight to 25 weeks for larger orders.
