Abstract
A peak of the radiation directivity of light emitted by each of LEDs is directed to a reflecting surface, and the light emitted by the LEDs is indirectly incident on an outer lens after reflection by the reflecting surface. Thus, problems, such as a local increase in brightness of a light emitting surface over areas corresponding to light emitting portions of the LEDs, are prevented. In addition, most of the light emitted by the LEDs is indirectly incident on the outer lens via the reflecting surface, so that dispersion of blue light and yellow light, which constitute the white light, by the outer lens is prevented. Thus, illumination light highly uniform in amount and color can be provided.
