Abstract
Provided is a lighting apparatus using light emitting diodes (LEDs) having a lateral heat radiation unit structure that can maximize heat radiation effect by employing an air vent structure causing atmospheric pressure difference between both side ends of an air circulation path. The lighting apparatus comprising a housing having a power supply accommodation space therein, a heat radiation unit that comprises an LED module accommodation groove that is installed on the top of the housing and having at least one inclined surface or mounting surface on which the LED module is mounted, and a number of fins that are formed on the outer circumferential surface of the LED module accommodation groove, an air circulation path that is lengthily formed between the housing and the heat radiation unit.
