Contribution of Phosphors in the Expansion of Addressable Markets for LEDs

Phosphors provide greater range of colors. The combination of yellow phosphors with blue LED improves the quality of white light, while high-quality red phosphors provide better color rendering. Existing phosphors can increase the LED efficacy by 100%, while reducing the price by 50-200%. New phosphor materials show promise to do even better. These characteristics of phosphors are helpful to expand markets where LEDs already have a market share, such as general illumination, and also markets where the penetration of LEDs are limited by consumer perception or performance concerns.
