PURPOSE: To obtain bright lighting which is low in power consumption with small-sized constitution by using a laser light beam for the lighting.

CONSTITUTION: The laser light beam is diffused by using individually or combining a convex lens, a concave lens, a convex mirror, a concave mirror, a plane mirror prism, etc., to illuminate an object surface directly, thereby obtaining lighting effect. Further, the laser light beam is sent in a fluorescent lamp and reflected to both sides by a body like a mirror to travel forth and back, and consequently the fluorescent material and the vapor of mercury and sodium in the fluorescent lamp are made to illuminate, thereby obtaining lighting power.
