Abstract

The present invention relates to a lighting apparatus. More specifically, the lighting apparatus comprises: an LED unit in which one of two surfaces forms a radiation surface having a plurality of LED elements mounted thereon and radiating light, and the other of the two surfaces forms a heating surface for emitting predetermined heat; a plurality of cooling units which are arranged vertically in the direction of gravity with respect to the heating surface of the LED unit and spaced a predetermined distance from each other in the left-right direction, and which have therein a refrigerant flow space filled with a phase-changeable refrigerant; and a lighting body in which the LED unit and the plurality of cooling units are installed, and a portion in the direction of the radiation surface is open. As a result, the lighting apparatus provides the advantage of maximizing cooling performance.

A lighting apparatus comprising:

an LED unit having a plurality of LED elements mounted on one surface of opposite surfaces to define a light-emitting surface from which light is radiated, the other surface defining a heat-generating surface to release a predetermined amount of heat;
a plurality of heat dissipation units respectively disposed vertically in an up-and-down direction along a direction of gravity with respect to the heat-generating surface of the LED unit, spaced apart from each other by a predetermined distance in a left-and-right direction, and having a refrigerant flow space formed therein and filled with a phase-changeable refrigerant;
and
a lighting body in which the LED unit and the plurality of heat dissipation units are installed and which is opened at a portion in the direction of the light-emitting surface.
