1. A light emitting element lamp comprising:
- a heat conductor having an emission opening portion at one end side, and a heat radiating member at another end side, wherein the heat conductor includes a recessed portion and is formed to be widened toward the emission opening portion from the other end side, wherein a peripheral surface of the heat conductor is exposed to an exterior of the lamp;
a cover portion having a surface attached to the heat conductor;
a substrate provided with a light emitting element, wherein a surface of the substrate is thermally connected to an inside surface of the heat radiating member and wherein the light emitting element in the lamp is disposed on the substrate; and
a lighting circuit housed in a space formed in the recessed portion of the heat conductor, wherein the lighting circuit is configured to light the light emitting element.

Abstract
A light emitting element lamp and a lighting equipment for suppressing a temperature rising of a substrate on which a light emitting element is mounted by using a reflector is described. Aspects relate to a lamp including a heat-conductive reflector, a base connected to the reflector, a heat-conductive heat radiating member, a substrate having a light emitting element mounted thereon and attached to the heat radiating member and a lighting circuit housed in the cover to light the light emitting element. Other components and features may also be included.
