Claim Text:
1. A lamp device comprising: a metallic device body having heat conductive properties, the device body including: a board fixed to the flat surface of the light source support through a screw, and being thermally connected to the light source support; a plurality of light-emitting elements provided around the screw and mounted on the board; a cover which is provided to the device body without using an adhesive so as to cover the plurality of light-emitting elements, while facing the flat surface of the light source support, a portion of the cover positioned inside the receiving portion contacting at least a part of the side surface of the light source support and contacting at least a part of the edge; a base portion provided so as to be power-feedable to the light-emitting elements; and a light-reflecting member, at least a portion of the light-reflecting member being positioned in the receiving portion, and provided along the first side of the edge and having a reflecting surface extending in at least the certain direction, the reflecting surface configured to reflect light from the plurality of light-emitting elements in a direction of the cover, wherein the edge has an external surface forming a first heat radiating surface of the heat radiating surface, and wherein a shape of at least a portion of the exterior surface of the device body reduces in diameter toward the base portion and the at least a portion of the exterior surface forms a second heat radiating surface of the heat radiating surface, the second heat radiating surface being different from the first heat radiating surface.
