A heat radiation structure of a light emitting element has leads, each lead having a plurality of leg sections, and a light emitting chip mounted on any one of the leads. The present invention can provide a high-efficiency light emitting element, in which a thermal load is reduced by widening a connecting section through which a lead and a chip seating section of the light emitting element are connected, and the heat generated from a heat source can be more rapidly radiated to the outside. Further, the present invention can also provide a high-efficiency light emitting element, in which heat radiation fins are formed between a stopper and a molding portion of a lead of the light emitting element so that natural convection can occur between the heat radiation fins, and an area in which heat radiation can occur is widened to maximize a heat radiation effect.

Light emitting element

Disclosed is a light emitting diode lamp that has low resistance to heat emitted therefrom. The LED lamp may include a heat coupling member thermally coupling a top part of a first lead to a top part of a second lead. The LED lamp may further include one or more top parts for lowering thermal resistance of the LED lamp. This configuration facilitates heat transfer from the first lead having an LED chip mounted thereon to the top part of the second lead and/or to the other top parts, lowering resistance to heat emitted from the LED lamp.
