Texas Instrument: Changing LED Color in Solid State Lighting

Texas Instrument Product Engineer David Zhang shares insights on LED color tuning technology in a recent blog post. As Tim Sullivan indicated in an earlier blog as well, LED lighting is a relatively new technology. Engineers that used to change bulb color through the glass fixture are now finding themselves figuring out how to change or tune lighting color in high-end LED fixtures. One of the easiest ways to do this is through multiple strings of different color LEDs with dimming. I wrote a paper, “Dimming multiple LED strings enables color-tunable luminaires”, on this topic that was published recently in LEDs Magazine. As well, I included a link below to a video demonstration on this topic.
