ABSTRACT:
A monolithic light-emitting device and driving method therefore includes a plurality of light-emitting diodes, array-arranged monolithically on a single substrate. The light-emitting diodes include a pn junction-containing semiconductor material and a phosphor-containing layer passing light emitted from the semiconductor material, absorbing part, or whole of the light for conversion into light having a different wavelength. 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 being 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. 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.
