PURPOSE: An LED device is provided to maximize a heat radiation effect by forming a plurality of sawtooth-shaped heat radiation elements around a heat radiator. CONSTITUTION: A heating device(110) includes a plurality of LED lamps(112). A heat radiator(120) discharges heat from the heating device to the outside. A plurality of heat radiation elements(122) are formed around the heat radiator to increase a heat radiation area. A circuit board(130) is separately arranged on the lower side of the heat radiator. A plurality of combination protrusions(142) are formed in an inner circumference of a housing(140). |
