New white LED technology from Fujikura

Filed under:

According to Nikkei Business Daily article, Fujikura has announced an alternative phosphor formulation for making white LEDs. The NBD requires a subscription, but the article is summarized at here. Most white LEDs use a phosphor to convert the light from a blue LED into yellow, which gives a white light when mixed. The interesting thing here is the improved efficiency of the phosphor material. Since the conversion isn’t perfectly efficient, light is lost in the conversion. Improving phosphor efficiency directly improves the lumen output of the finished product.

Interestingly, the press release isn’t available on Fujikura’s site yet.
