ABSTRACT:
Structure is provided to protect a lamp body from the heat generated by a bulb without impairing the external appearance of a lamp or increasing the number of parts of the lamp. A lamp body incorporates a reflector, a bulb, and a shade for limiting the scope of light rays projected from the bulb. The shade has an upper shade portion and a lower shade portion which are integral with each other. The upper shade portion shields those of the light rays that would become dazzling light out of all of the light rays projected from the bulb. The lower shade portion shields those of the light rays from bulb projected toward a lower surface portion of the lamp body. The lower shade portion prevents direct projection of the light rays onto the lower surface portion of the lamp body by shielding the light rays from the bulb, which in turn prevents the lower surface portion of the lamp body from being overheated by the bulb. A part of the reflector extends over the lower surface portion of the lamp body, so that a problem of impairment in the external appearance of the lamp due to the lower surface portion of the lamp body being seen from outside is eliminated.
