PURPOSE: A lighting apparatus is provided to efficiently emit heat from an LED by mounting a heat sink on an inside curved surface of a heating element. CONSTITUTION: An upper plate(110) is arranged to cover the upper opening of a heating element(140). The upper plate includes a reflector for reflecting light, which is incident from a plurality of light source parts, to a light emitting path. The light source part includes an LED and a substrate on which the LED is arranged. A lower plate(150) includes a light emitting opening to pass through lights reflected by the reflector. A cover(160) includes a light collecting part which gathers lights, passing through the light emitting opening, into the light emitting path. |
