ON Semiconductor LED Lighting – enabling efficent solutions

LEDs are inherently low voltage devices and depending on the color and current, the forward voltage of the LED can vary from less than 2 to 4.5 V. In addition LEDs need tob e driven with a constant current to ensure the intensity and color desired. This requires power conversion and control solutions to interface tot he various power sources, be it the AC line, a solar panel, a 12 V car battery, a DC power supply or low voltage AC system or even primary Alkaline and Ni-based cells or rechargable Li-Ion battery cells. ON Semiconductor has focused on applying our low voltage and high voltage technologies and our expertise in power management solutions to the challanges of solid state lighting.
