The radiation directivity peak of light emitted from each LED (22) is directed to a reflection surface (35a), and the light emitted from the LED (22) is indirectly outputted to an outer lens (30) after being reflected by the reflection surface (35a). Thus, troubles, such as local increase of luminance of a part of a light emitting surface (30a) that corresponds to the light emitting section of the LED (22), are eliminated. Furthermore, since most of the light emitted from the LED (22) is indirectly inputted through the reflection surface (35a), blue light and yellow light constituting white light are prevented from being diffused by the outer lens (30). Thus, illuminating light having excellent uniformity in emission quantity and emission color is obtained. |
