White light emitting device |
摘要 |
A white light emitting device includes a device having at least one light emitting diode (LED) serving as a light source and being capable of emitting a light between blue and green in color; and a phosphor consisted of first and second phosphors each made of a compound from different materials. The phosphor is excited by the light from the light source to emit a first-color light and a second-color light, which are both blended with a portion of the light and altogether release to obtain a white light having enhanced color rendering effects, thereby offering the white light with illuminant contrast.
