POINT LIGHT SOURCE AND OPTICAL DEVICE COMPRISING SAME

摘要

[PROBLEMS] To provide a small multicolor light source. [MEANS FOR SOLVING PROBLEMS] A housing (2) has an inner cavity (4) which has a concave inner wall surface with a high reflectance. The housing (2) is provided with one or more light outlets (6) communicating from the inner cavity (4) to the outside. The light outlet (6) has a hole small enough to be regarded as a point light source. A plurality of light-emitting bodies (8) are arranged in the cavity (4) while being directed not to face the light outlet (6) directly. The light-emitting bodies (8) are arranged uniformly in a circle along the inner wall surface in the plane perpendicular to an axis passing through the hole of the light outlet (6).
