PURPOSE:To relatively easily obtain various irradiation light distributions by providing the first reflector transmitting part of the light and reflecting the remainder at the middle section of a lamp body, and providing the second reflector reflecting the lamp permeating the first reflector at the upper section of the light body. CONSTITUTION:The light from a luminous section 2 is partially reflected by the first reflector 5 and radiated from the side face. The light permeating the first reflector 5 is reflected by the second reflector 6 and likewise radiated from the side face. When respective irradiation light distributions are changed in the first and second reflectors, various overall irradiation light distributions are obtained. If each reflector has two kinds of irradiation light distributions, for example, four kinds of overall irradiation light distributions are obtained. The first reflector 5 reflecting part of the light and passing the remainder is used, thus various irradiation light distributions are obtained via the vertically located first and second reflectors. |
