PURPOSE: A lighting apparatus is provided to change blue light emitted from a plurality of light source parts into white light by arranging optics between a plurality of light source parts in a heating element and a cone reflector in an inner surface of an upper plate. CONSTITUTION: An upper plate(110) is installed to cover an upper opening of a heating element(140). The upper plate is composed of an exterior surface and an inner surface. A reflector reflects light, which is incident from a plurality of light source parts, to a light emitting path. A lower plate(150) is arranged in a bottom opening of the heating element. A cover(160) includes a light collecting part which collects lights, passing through the light emitting opening on a top part, to the light emitting path. |
