KR101164066B1 - Illumination housing of LED bar heat sink with radiant heat, moisture-proofing and waterproof - Google Patents

Abstract

The present invention relates to a luminaire having a bar-type heat sink for efficiently dissipating heat generated from a printed circuit board on which an LED is mounted. Heat generated from LEDs decreases the lifespan and the amount of light of LEDs, causing technical and economic problems, and researches for solving them are very active. Existing LED bars used for interior and exterior lighting have problems in efficient use due to the limited output of light by applying a current far below the LED's original capacity for heat dissipation, and open type for moisture proof and waterproof. The use of fillers, such as silicon, in aluminum bars was uneconomical in terms of appearance, environment and durability. In the present invention, by applying a current corresponding to the capacity of the LED standard, the amount of light is greatly increased, and a bar type heat sink having a slide structure can be developed to easily mount a plastic cover for moisture and water resistance. Economic problems can be solved.
