Method and system for configuring high CRI LED

摘要

A method and a system for configuring a high CRI LED is provided in this invention, by using an algorithm to compute which of at least two phosphors that can be mixed with the LED. A mixed-emitting spectrum can provide a high CRI white light at a predetermined color temperature. The proposed method for configuring high CRI LED comprises the steps of:
calculating a standard spectrum, wherein the standard spectrum is a visible spectrum radiated from a blackbody with a first color temperature;
providing an emission spectrum of an LED; an emission spectrum of a first fluorescent powder, and an emission spectrum of a second fluorescent powder; and
adjusting the first fluorescent powder and the second fluorescent powder based on the standard spectrum to generate a first mixed-emitting spectrum.
