The disclosure herein describes an information displaying traffic sign which comprises a board, the front side of which is formed of dusters of LED devices. Visors are mounted to the front of the board, each visor being provided with an opening on its top face so that vertical air circulation along the front side of the board may be permitted to cool the LED devices. Shades are provided, adjacent to each visor opening, to prevent sun rays from reaching the LED devices.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] An information display sign comprising:a board having a front side;clusters of actuatable LED devices mounted on said front side and arranged in columns and rows;a LED protecting cap extending substantially perpendicularly from said front side of said board for each said cluster of LED devices; said protecting cap defining a body including:(i) an inner part defining a cavity at least partially enclosing said cluster, said cavity being formed of a base, opposite sides converging to define a dome-shaped top wall;(ii) an extending part formed of opposite side walls integral with said opposite sides of said inner part and converging to define a curved top surface and including lower edges on opposite sides of said top surface which are obliquely-truncated; said top surface including a rectangular opening in a portion of said dome-shaped top wall and extending from one side to an opposite side and having a frontmost side; the rectangular openings of a column of clusters being aligned so as to define an unobstructed air passage therethrough to cool said LED devices; said opposite sides of said inner part protecting said LED devices from side light incidence thereon; and shade means comprising a wall extending from said top surface at the frontmost side of each said rectangular opening, each said shade means being disposed in alignment with one another to prevent sunlight impairment and UV radiation from falling onto the LED devices through said openings.
