RAIL PIXEL MODULE AND ELECTRIC SIGN BOARD WITH VENTILATING STRUCTURE USING THE SAME THAT INTERCEPT BACKWARD LIGHT AND GUIDE VENTILATING PATH

摘要

The present invention provides a substrate having an LED driving circuit, an LED installed on the substrate and flickering according to an electrical signal, and first and second through holes for fixing a portion of the LED to penetrate in the longitudinal direction. And a sum of an upper extension extending a predetermined length upward from a top end of the first through hole and a lower extension extending a predetermined length downward from a lower end of the second through hole. A pixel including a fixing plate formed smaller than a vertical length between the lowermost end of the fixing plate and the uppermost end of the second through hole, and a front light blocking plate extending a predetermined length from the front surface of the fixing plate to prevent deterioration of brightness of the LED due to sunlight interference. In the module of the signboard, to block the light irradiated to the front from the rear of the fixing plate, to induce a path of the ventilated wind A rail pixel module for inducing rear light blocking and a ventilation path including a plurality of rail pixel modules including a rear light shielding plate which is inclined to extend from the bottom of the fixing plate, and a case for fixing the plurality of rail pixel modules to be spaced apart from each other by a predetermined distance. And it relates to an electronic sign of the ventilation structure using the same.;LED, electronic board, shading board
