[0032] Light is reflected sequentially by reflector 2 and first reflective surface 3. The surface of reflector 2 or first reflective surface 3 is provided with patterns or textures to improve the uniformity of light. After multiple reflections, the light output is more uniform, and the light output effect is consistent from all angles, thus resulting in a good lighting effect.
