Vishay Intertechnology has introduced two cold white LED power modules called the VLSL40xxA and the VLSL50xxA. Each metal-core based module is integrated with36, 24 or 12 high-brightness LEDs.
The VLSL40xxA can be used to adjust the emission characteristics of the modules by using optional special reflectors, while the VLSL50xxA has a clear silicone lens to offer a butterfly-shaped radiation quality. These modules have optimal luminous efficiency, which makes them suitable for internal building lighting, tunnel lights, streetlights and other common lighting applications.
The VLSL40xxA and the VLSL50xxA provide a color temperature that ranges from 5000 K to 7000 K. Both modules have a metal-core, a shimmering white surface, and a one-side PCB with a Cu thickness of below 0.75 ƒÝ. Each device features at least 18 ƒÝ Cu thickness conductive top layer and a 63 ƒÝ prepreg 1080 FR4 type isolation layer.
The VLSL40xxA comes with the VLSL-REFL01 reflector that is made up of an aluminum-alloy material with a less-polished surface. The emission of the module can be regulated in a typical range between 120„a and 50„a by using various combinations of reflectors. The VLSL50xxA¡¦s clear silicone lens permits a 60„a horizontal angle and a 35„a vertical of semi intensity.
The VLSL50xxA and the VLSL40xxA use InGaN technology and offer current to a maximum of 700 mA. These devices have normal solder mask material and provide color binning and luminous flux. They offer ESD that can bear voltage up to 2 kV as per JESD22-A114-B standards.
