摘要： A white light emitting apparatus includes a light source section in which a first white LED that emits white light whose chromaticity deviates to a blue side from a predetermined white region of a CIE chromaticity diagram and a second white LED that emits white light whose chromaticity deviates to a yellow side from the predetermined white region are adjacently disposed so as to emit light with optical axes in substantially the same direction, and a current regulator that independently drives the blue LED chip in the first and second white LEDs, respectively. A color mixture of lights emitted from the first and second white LEDs is adjusted to a chromaticity of the predetermined white region using the current regulator.

摘要： A white light emitting apparatus (20) is provided with a first white light emitting diode (11) that emits yellowish white and a second white light emitting diode (12) that emits bluish white in the same direction of the light emitted from the first white light emitting diode (11). The white light emitting apparatus (20) is further provided with a current control circuit that controls drive currents of the first and second white light emitting diodes (11, 12).
