PROBLEM TO BE SOLVED: To provide a lighting tool body facilitating manufacturing including assembly, excellent in heat conductivity and heat radiation, and capable of controlling light from a light source.SOLUTION: A lighting tool body includes: a body 11 to which a light source 15 is attached; a reflector 12 directly reflecting light from the light source 15; and a heat radiation fin 13 radiating heat transmitted from the light source 15 through the body 11. The body 11, the reflector 12 and the heat radiation fin 13 are integrally molded by extrusion processing or extraction processing of metal, and are formed so as to be long in an extrusion direction or extraction direction.SELECTED DRAWING: Figure 1 |
