[0002] The projection wall lamp is mainly composed of a light source, a reflector, a lens, a pattern wheel and the like. The light source generates light, which is focused and shaped by the lens to become parallel light or a light beam with a specific angle. When the light passes through the pattern wheel, the pattern or text on the pattern wheel will shield or transmit the light, so as to form corresponding patterns, texts or images on the projection surface. For example, a pattern projection lamp is disclosed in patent CN108286676A.
