HEAT DISSIPATION STRUCTURE OF LED LAMP USING CONVECTIVE FLOW

摘要

PURPOSE: A heat dissipation structure of an LED lamp is provided to improve power supply efficiency by arranging an LED power circuit including a rectifier in a heat dissipation frame. CONSTITUTION: A heat dissipation frame(120) includes a main plate(122) and a heat dissipation unit(124). The heat dissipation unit is arranged in a top surface of the main plate. A heat dissipation hole(122h) is formed in the main plate. The heat dissipation hole induces convection of an air, and cools the LED module. The heat dissipation unit includes a plurality of heat dissipation plates(124p) and a heat dissipation slit(124s). The heat dissipation plates are parallel arranged into one direction. The heat dissipation slit is formed between a pair of heat dissipation plates. The heat dissipation hole is connected to the heat dissipation slit. A through hole(124h) is formed in the heat dissipation plate in order to connect a pair of heat dissipation slits.
