RADIANT PLATE USING LATENT HEAT FOR STREET LIGHT OF LED

摘要

PURPOSE: A heat sink is provided to efficiently discharge heat from an LED(Light Emitting Diode) by filling a phase change material between the upper and lower plates. CONSTITUTION: A heat sink includes an upper plate(12), a lower plate(11), and a phase change material(13). An LED module(20) is attached to the lower side of the lower plate. An LED module is comprised of a PCB and a plurality of LED devices. The upper plate is arranged on the lower plate. A plurality of heat radiation fins is formed on the upper and lower plates with a constant space. The phase change material is filled between the upper and lower plates.
