PROBLEM TO BE SOLVED: To provide an illumination device which is equipped with a reflector by which light from a light source is guided to at least two foci in a lighting state wherein the light source is turned off according to a demand without heat problems caused by unnecessary lighting. SOLUTION: In the illumination device equipped with the light source and the first reflector to guide the light from the light source to at least two foci in the lighting state, a light path to at least one of the two foci needs to be shut out without heat problems caused. To this end, at least one reflector is installed which selectively changes the directions of light to the second one of the two foci, if necessary, that are guided by the first reflector to the first one of the two foci, at least partially, and directly or indirectly. |
