Abstract
A multicolor light emitting diode lamp includes a blue LED and a AlGaInP-based red LED having high luminescence efficiency, balancing with the blue LED are mounted in the same package. The red LED includes a light emitting section including a light emitting layer having a composition formula, (AlGa)InP (0≦X≦1 and 0<Y≦1). The red LED emits at least as many photons as the blue LED when the same electric current is flowed. When a strong red light is desirable for plant growth, by mounting two red LEDs and one blue LED, a desired mixed color is obtained with one lamp, and irradiation of light can be made uniform.
