Vishay has released two metal-core-based, cold white LED power modules, each assembled with 12, 24 or 36 high-brightness LEDs. The VLSL40xxA is designed for flexible use by utilising optional special reflectors to adjust the modules’ emission characteristics.
The VLSL50xxA features a clear silicone lens for a butterfly-shaped radiation characteristic.
Optimised for illumination in streetlights, internal building lighting, tunnel lights and general lighting applications, the VLSL40xxA and VLSL50xxA offer a colour temperature range of 5000 K to 7000 K. Both devices feature a shiny white surface and a metal-core, single-side PCB with a copper thickness > 0,75 μm. Each module includes a conductive top layer with a minimum Cu of 18 μm and a 63 μm 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°. The clear silicone lens of the VLSL50xxA allows for a ±35° vertical and ±60° 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 colour binning. The devices provide ESD withstand voltage up to 2 kV in accordance with JESD22-A114-B and comply with ROHS 2002/95/EC.
