Abstract
A cover for a LED sign is manufactured from a stainless steel sheet that is dimensionally larger than the array of light emitting diodes comprising the LED sign. The stainless steel sheet is laser cut and then bent to simultaneously form a plurality of apertures and a corresponding plurality of louvers each extending adjacent one of the apertures. The apertures facilitate viewing of the LED sign and the louvers shield the light emitting diodes comprising the LED sign from excessive light.
