Provided is a light-emitting lamp (1) that uses a heat conductive case (2) and a heat conductive cover (5) to effectively suppress increased temperature for a substrate (9) on which a light-emitting element (4) is mounted. The light-emitting element lamp (1) is equipped with the heat conductive case (2), a light source part (3), the heat conductive cover (5), and an insulating cover (6). The heat conductive case (2) has an irradiation opening (2b), and is formed to flare out toward the irradiation opening part (2b), while its outer peripheral surface is exposed outward and a substrate installation part (2c) is provided on the inner peripheral surface. The light source part (3) has a substrate (9) on which the light-emitting element (4) is mounted, and the substrate (9) is installed thermally bonded to the substrate installation part (2c) of the heat conductive case (2). The heat conductive cover (5) is connected thermally bonded to the outer peripheral surface of the heat conductive case (2) with the surfaces thereof in contact. One end of the insulating cover (6) is connected to the heat conductive cover (5) and a base (7) is connected to the other end. A lighting circuit (12) controls lighting of the light-emitting element (4) housed in the insulating cover (6). |
