Vishay Intertechnology Releases Metal-Core-Based, Cold White LED Power Modules

Vishay Intertechnology, Inc. (NYSE: VSH) today 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, while 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 > 0.75 µm. Each module includes a conductive top layer with a minimum Cu of 18µm 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 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.
