Wei launched 0.75mm thick high brightness white LED

American world semiconductor (Vishay Intertechnology) listed in the shape of 3.3mm x 3.4mm x 0.75mm, maximum luminosity of 18000mcd white LED "VLMW82". The product can be used for the camera flash, the car's brake lights / steering lights and dashboard panel backlight, as well as emergency lighting, etc..

This is a GaN material in the use of blue LED on the combination of TAG (TB aluminum garnet) is a fluorescent material developed from the white LED. The maximum forward current is 500mA and the maximum forward voltage is 4.3V. The standard state of the beam is 35lm (500mA). The luminous efficiency is 40lm/W (when the input current is 100mA). The luminous color is in accordance with the CIE chromaticity diagram (x=0.33, y=0.33).

Surface mount ceramic package "CLCC-2". Thermal resistance is 20K/W. The half peak angle of the encapsulated radiation is 60 degrees. Products comply with the United States JEDEC ESD (electrostatic discharge) voltage specification "JESD22-A114-8". At present, the sample has been supplied, the production volume is scheduled to begin in July 2008.
