The power LED driver can be applied to an off-line topology called RAIS. It is a technology with TRIAC dimmer compatibility and near unity power factor with no loss in any efficiency. Besides, it is especially suited to use with domestic TRIAC dimmers. The RAIS is a single stage supply that also delivers a constant current output to the LED with no sense resistor.
The power has to do with the voltage and the current, and there has relatively influences between the two. Small voltage change result in a large change in current. In the power LED driver, if the voltage is too high, then the current will go above the maximum rating, heating and possibly destroying the LED.
Customized products are available in SOC's product line that are modified to meet each customer's individual requirements. Regarding form factor and feature set; modifications to standard SOC's power LED products may include:
Integrated to Light-emitting diode lighting for indoor and outdoor / Non-Isolated configuration.
