Abstract
A light emitting diode lamp is composed of a reflective mirror, a pillar and a plurality of light emitters disposed in radial arrangement about a focal point of the reflective mirror on the surface of the pillar. Each of the plurality of light emitters is composed of a light emitting diode and a lens forming a virtual image in a position of the focal point located behind the light emitting diode. Additionally, a plurality of light emitting diode elements composing the light emitting diode in each of the plurality of light emitters emit light rays with the same wavelength, and the light emitting diodes in the plurality of light emitters emit the light rays with at least two types of wavelength.
