Abstract
(EN)
Provided is a cooling unit for an LED lighting apparatus, which dissipates heat that is generated in the lighting apparatus using an LED. The cooling unit for an LED lighting apparatus includes a heat pipe, one end of which is coupled to the LED lighting apparatus, and which uses a medium in which powder having an infrared-emitting property is mixed into a working fluid, wherein a heat-sink fin is disposed on the other end of the heat pipe. The LED lighting apparatus including the cooling unit for the LED lighting apparatus includes: a mounting plate made of a metal material and coupled to the cooler; an LED board on which one or more LEDs are arranged, the LED board being disposed on the mounting plate; and a driving circuit for driving the LEDs arranged on the LED board. The LED lighting apparatus may be applied to outdoor or indoor lights in which high light intensity is required, such as streetlights, fish-luring lights, floodlights, etc.

La présente invention concerne une unité de refroidissement pour un appareil d'éclairage à DEL, dissipant la chaleur produite dans l'appareil d'éclairage à DEL. L'unité de refroidissement pour un appareil d'éclairage à DEL comprend un caloduc, dont une extrémité est accouplée à l'appareil d'éclairage à DEL, et utilisant un milieu dans lequel de la poudre présentant une propriété d'émission d'infrarouges est mélangée dans un fluide de travail, une ailette de dissipateur thermique étant disposée sur l'autre extrémité du caloduc. L'appareil d'éclairage à DEL comprenant l'unité de refroidissement pour l'appareil d'éclairage à DEL comprend : une plaque de montage composée d'un matériau métallique et accouplée à l'appareil réfrigérant ; une carte à DEL sur laquelle une ou plusieurs DEL sont disposées, la carte à DEL étant disposée sur la plaque de montage ; et un circuit d'attaque destiné à piloter les DEL disposées sur la carte à DEL. L'appareil d'éclairage à DEL peut être appliqué sur des éclairages d'extérieur ou d'intérieur dans lesquels une forte intensité lumineuse est requise, tels que des réverbères, des lumières d'attraction de poisson, des projecteurs pour grande surface, etc.
