LAMP COVER, LAMP HAVING THE SAME AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention relates to a lamp cover, a lamp having the same and a method for manufacturing the same. A lamp cover (200), wherein, at least one section of at least one surface of the lamp cover (200) includes alternant convex ridge (201) and concave groove (203), wherein, in a contour of the at least one section obtained along a direction orthogonal to an extending direction of the convex ridge or concave groove, contour sections of each convex ridge (201) and each concave groove (203) are arcs, and arcs of adjacent convex ridges and concave grooves are tangent. Such a lamp cover may avoid dark lines from being formed on the illumination surface and obtain good illumination uniformity.
