Abstract: An LED lighting device produces subdued and surface light that does not damage people's eyes, has a concave top, an open bottom and two ends and comprises two supports, a reflector, a housing cavity, a mounting base and an LED strip. The two supports are mounted respectively at the two ends parallel to each other, and each support has an inner surface. The reflector is a concave non-metallic white reflective sheet, mounted longitudinally between and attached to the two supports, and has an inner surface. The housing cavity is formed between the two inner surfaces of the two supports and the inner surface of the reflector. The mounting base is mounted longitudinally between and attached to the two supports and has two rails. The LED strip is mounted movably between the two rails and has at least one LED facing the inner surface of the reflector to emit light.
