LED FLOODLIGHT OF ADJUSTABLE AIR COOLING HEAT DISSIPATING CAPABILITY

摘要

The present invention relates to an LED floodlight. The LED floodlight comprises a casing (10) composed of a casing body (11) and a rear cover (12) detachably coupled with the rear side of the casing body (11). A heat radiation base plate (21) absorbing heat generated in an LED module (20) is fixed to the inside of the casing (10) by forming a plurality of longitudinal grooves (11a) on an outer wall of the casing body (11) and mounting a plurality of LED modules (20). A groove (21a) is formed at the bottom of the heat radiation base plate (21) for increasing an area for heat generated in the LED module in contact with air in an inner space (S) of the casing (10). A radiator (40) is arranged across the inner space (S) to make the upper surface be in contact with the bottom of the heat radiation base plate (21) and the lower surface be in contact with the bottom of the rear cover (12). The heat generated in the LED module and transferred through the heat radiation base plate (21) in contact with the upper surface is discharged into the inner space (CS) by fixing the upper surface to the heat radiation base plate (21).
