OSRAM Opto Semiconductors Thursday announced that it has developed a high-flux LED prototype with a feel-good effect in its laboratory. OSRAM claims that the prototype offers three important properties essential for general illumination applications, namely a color temperature of 3000 K, a color rendering index of 82 and an efficiency of 104lm/W.

Mixing luminescence phosphor with silicone and dispensing it on a blue light emitting chip is a common LED package method in producing white light. The quality of white light depends heavily on the uniformity of phosphor on the blue die. Often times, when coupling secondary lens on white LED, it will reveal yellow circling. Such yellowing greatly shadows the quality of white light.
