Abstract:
1. A monolithic light emitting device for lighting comprising a plurality of light emitting diodes array-arranged monolithically on a single substrate, wherein the light emitting diodes comprise a pn junction-containing semiconductor material and a phosphor-containing layer passing light emitted from the semiconductor material, or absorbing part or the whole of the light for conversion into light with a different wavelength, and the array is constituted of a light emitting diode group consisting of m (m≧2) pieces of the light emitting diode, the light emitting diode group is constituted of N types (N≧2, providing N≦m) of light emitting diodes each having either one of preset N types of light emitting spectrum patterns, and an average light emitting spectrum from the whole array can be changed by regulating a power supplied to the light emitting diodes for each light emitting diode group sorted according to the type of the light emitting spectrum pattern.
