Abstract:
1. A light-emitting device comprising: a substrate; a semiconductor light-emitting array formed above the substrate and emitting a first light with a first spectrum, wherein the semiconductor light-emitting array comprises a first light-emitting unit, a second light-emitting unit and a third light-emitting unit; a first wavelength conversion layer formed above the first light-emitting unit and radiates a second light with a second spectrum excited by the first light; a second wavelength conversion layer formed above the second light-emitting unit and emitting a third light with a third spectrum different from the second spectrum excited by the first light; and an electric circuit layer electrically connecting the first light-emitting unit, the second light-emitting unit and the third light-emitting unit in a connection fashion such that the first light-emitting unit and the second light-emitting unit emit light alternatively with a predetermined clock when driven by a power source, and such that the third light-emitting unit and the second light-emitting unit emit light alternatively with a predetermined clock when driven by the power source, wherein the third light-emitting unit radiates the first light with a first spectrum different from the second and third spectrums; wherein a third wavelength conversion layer is formed on the third light-emitting unit; and the third wavelength conversion layer emits a fourth light with a fourth spectrum different form the second and the third spectrums excited by the first light; and wherein the electric circuit layer electrically connects the first light-emitting unit with the third light-emitting unit in a serial configuration, and connects the first light-emitting unit and the second light-emitting unit in an anti-parallel configuration.
