PURPOSE: An LED lamp is provided to improve uniformity factor of light by installing an LED module on each edge of a heat dissipation frame in which a through hole is formed in inside and to multiply cooling efficiency. CONSTITUTION: A heat dissipation frame(3) releases heat created due to the radiation of an LED module. A diffusion cover(4) multiplies a spreading angle of light emitted from the LED module. A base part(5) is installed on the upper side of the heat dissipation frame and is electrically combined to a socket. A bonding part(7) interlinks the base part and the heat dissipation frame. A lid part(9) is installed in the lower side of the heat dissipation frame. A ventilation part in which one or more ventilation grooves are formed is included in the heat dissipation frame. |
