Abstract
The present invention provides a light-emitting element lampcapable of preventing a temperature rise of a substrate, on which light-emitting elementsare mounted, by effectively utilizing a thermally conductive casingand a thermally conductive cover The light emitting element lampincludes a thermally conductive casing, a light source part, a thermally conductive cover, and an insulative cover. The thermally conductive casingincludes an irradiation opening, is formed so as to be widened toward the irradiation opening, has its outer circumferential surface exposed outwardly, and has a substrate mounting partsecured on its inner circumferential surface. The light source parthas a substratehaving the light-emitting elementsmounted thereon and causes the substrateto be thermally coupled to and attached to the substrate mounting partof the thermally conductive casing. The thermally conductive coveris thermally coupled to and connected to the outer circumferential surface of the thermally conductive casingin a surface-contacted state. The insulative coverhas one end side thereof connected to the thermally conductive cover, and the capis connected to the other end side thereof. The lighting circuitcontrols lighting of the light-emitting elementsaccommodated in the insulative cover
