ON Semiconductor has application notes on how to harness the LED lighting technology, this enables you to design your LED based products like Flashlight and LED Ballasts for Home/Office Lighting.
The long term savings on energy cost not only offsets the Initial Investment on LED Lighting but also cuts your expense on a long term for energy and replacement costs. LED Lighting solutions are very reliable, but is is important to integrate it with high quality engineered power electronics. So a Customer/Consumer has to choose quality tested and standardized products and be very shrewd in purchase decisions. Then we have a Bright future for LED Lighting
Low Voltage AC LED Reference Design Board
Powering high brightness LEDs from the AC line utilizing a step down isolation transformer. Drive three 350 mA high brightness LEDs. A linear regulator with two discrete transistors and a sense resistor maintains constant current through the LED Lamps. See also LV AC LED Drive - EEM.
High Brightness LEDs (HB-LED) and High Power White LEDs for energy efficient Solid State Lighting (SSL).
