Abstract:
1. A lighting device comprising: at least one illumination module; and a frame in which the illumination module is installed, wherein the illumination module includes a cooling part, a substrate having an LED matrix formed thereon so as to be attached onto a bottom surface of an upper part of the cooling part through a thermal conductive insulation pad, a PCB having a through-hole matrix so as to be installed at an upper part of the substrate and connected with each LED terminal on the substrate, and a lens cover having a lens matrix so as to be installed at an upper part of the PCB; wherein a recess, which allows an LED of the LED matrix to be installed in an interior of the recess and has a wall surface to be an incident surface, is formed on a central part of a first side surface of each lens of the lens matrix, a light emitting surface, which protrudes to have an arc-shape similar to a pillow, is formed at a central part of a second side surface, and a perfect reflection surface, which surrounds the recess and reflects light to the light emitting surface, is formed at the first surface of the lens; and wherein the LED passes through a corresponding PCB through-hole on the PCB so as to be installed within the corresponding recess; wherein a plurality of cooling fins is installed at the cooling part; and wherein the frame is divided into at least one installation hole by a plurality of frameworks arranged in longitudinal and latitudinal directions while intersecting each other, the signal illumination module is installed within the installation hole, a installation strip having screw holes is formed at both sides of the cooling part of the illumination module, screw apertures corresponding to the screw holes are formed at each framework surrounding the installation hole, a main body of the illumination module is disposed within the installation hole, and the installation strip of the cooling part is arranged on the framework and is assembled with the screw holes and the screw apertures by strip screws so as to fix the illumination module in the framework.
