Patent ID: 8384275

Claim:
A light emitting element lamp comprising: a heat conductor provided, at one end side, with an emission opening portion, and at another end side, with an inside flat heat radiating member and a recessed portion on a back surface side of the heat radiating member, the heat conductor being formed to be widened toward the emission opening portion from the another end side, and having a reflector provided on an inside surface, a peripheral surface of the heat conductor being exposed to an outside, the heat-conductor and the heat radiating member being integrated so as to form a tubular shape; a cover portion formed of a metal material into a tubular shape and having a one side attached to the another end side of the heat conductor so as to be connected to the recessed portion of the heat conductor and having a base on another end side, the recessed portion being formed inside the cover portion; one single print substrate provided with a plurality of light emitting elements and attached to the heat radiating member with a substrate surface being thermally connected to the inside flat surface of the heat radiating member in a face to face surface contact state, wherein all of the light emitting elements in the lamp are disposed on the one single print substrate; an insulating protection tube accommodated inside the recessed portion; and a lighting circuit housed inside the insulating protection tube accommodated in the recessed portion in a space formed in the cover portion and the recessed portion in a manner apart from the back surface of the heat radiating member of the heat conductor so as to light the plurality of light emitting elements.
