Light irradiating device

Abstract

Abstract PURPOSE:To transfer heat conducted to a case by lamp irradiation, to a reflecting body, and to restrain a heat radiation to the outside, by interposing a heat conducting layer, consisting of metallic filaments having high heat conductivity, between the reflecting body and the case. CONSTITUTION:A light irradiated from a lamp 1 irradiates a body 7 to be irradiated moving with a transferring body 8, to perform a prescribed treatment, but a part of the light irradiates both side surfaces 5a of a case 5. Accordingly the temperature of irradiated part rises and the temperature of an upper surface part 5b is elevated by its conducted heat, thereby heating the whole case 5 to high temperature. A heat conducting layer 6 is, however, interposed between the case 5 and a reflecting body 2, and then the conducted heat of the case 5 is rapidly transferred to the reflecting body 2 by a large number of metallic filaments which form the heat conducting layer 6, and the heat is exchanged with cooling water 4 flowing through the inside of the body 2; therefore, the heat radiation to the outside of the case 5 is well inhibited.
