LIGHT EMITTING DEVICE LAMP

摘要

PURPOSE: A light emitting device lamp is provided to improve radiant heat performance by maximizing a contact area of a housing and a radiating unit by delivering heat generated from an inside housing formed with high thermal conductivity materials to the radiating unit. CONSTITUTION: A light emitting device lamp comprises a light emitting unit(10) including more than one light emitting device; a power circuit unit for supplying electricity to the light emitting unit; a radiating unit(30) in which the light emitting unit is mounted, and which emits heat generated in the light emitting unit; and a housing(40) surrounding a part outer periphery of the radiating unit with contacting, and delivering heat generated from the power circuit unit to the radiating unit.
