PURPOSE: A lighting device is provided to improve heat dissipation by converting heat from a light emitting device to infrared rays to be discharged to the outside. CONSTITUTION: A light source unit(200) is arranged on a heat radiation element(100). An infrared radiation layer is arranged on the surface of the heat radiation element and emits far or near infrared rays. A reflector(500) reflects the infrared rays from the infrared radiation layer and surrounds the heat radiation element. A heat radiation sheet is arranged between the heat radiation element and the light source unit. |
