PURPOSE: An LED(Light Emitting Diode) device is provided to control a light irradiation range by controlling an angle of a pair of irradiation units. CONSTITUTION: A pair of illumination units(10) are respectively arranged on left and right sides of an LED device. One pair of radiation units(20) includes a plurality of radiation fins and a radiation plate. The radiation plate is coupled with an upper side of each illumination unit. A plurality of radiation fins are formed on the upper side of the radiation plate with various heights. A fixing unit(30) is combined between a pair of radiation units. An angle controller(40) includes a control plate, a stopper, and a clamping bolt. A hinge shaft is formed on one end of the control plate. The sawtooth of the stopper is engaged with the sawtooth of the control plate. |
