    Abstract: PURPOSE: A cover for an LED lighting device capable of controlling a light source using a double pattern layer is provided to illuminate a large area by forming a micro pattern back and forth. CONSTITUTION: A double pattern layer includes an inside micro pattern(7) and an outside micro pattern(6). The inside micro pattern is formed on the inner surface of a cover(3). The outside micro pattern is formed on the outer surface of the cover. The double pattern layer controls the shape and direction of light by changing the arrangement position or combination of the inside micro pattern and the outside pattern.
