PROBLEM TO BE SOLVED: To shine a lamp in a novel way having a sense of depth at the time of illuminating when the lamp has a plurality of light-emitting diodes. SOLUTION: For example, eight light-emitting diodes 20 are used as a light source and placed around an optical axis Ax of a reflector 22 with 90 deg. pitch doubly. A reflective surface 22a of the reflector 22 is formed from small reflective surfaces A1, A2, A3 and A4 formed around the optical axis Ax with 90 deg. pitch radially to reflect light from each light-emitting diode 20A on an inner peripheral side and second small reflective surfaces B1, B2, B3 and B4 formed between the small reflective surfaces to reflect light from each light-emitting diode 20B on an outer peripheral side. When the reflector 22 is observed from a front at the time of illuminating, each small reflective surface and each second small reflective surface shine by reflecting light from the light-emitting diode 20 close to them and also shine by reflecting light from another light-emitting diode 20 so that the reflective surface 22a is seen to shine having a sense of depth. Moreover, the reflective surface 22a is seen in a different shining way in response to movement of point of view in sequence. |
