Abstract
The utility model provides a lamp. The lamp comprises a shell body and a light source. The lamp further comprises a liquid crystal box. The liquid crystal box is arranged on the light emitting surface of the lamp. An isolation portion is arranged in the liquid crystal box. The isolation portion forms a plurality of separated liquid crystal material containing areas in the liquid crystal box. The refractive index of liquid crystal materials can be changed according to the change of the voltage exerted at the two ends of the liquid crystal materials. Due to the fact that different voltages are applied to each liquid crystal material containing area at different times, the refractive index of each liquid crystal material containing is changed. Light rays emitted by the light source are refracted by different areas to form change of lightness and darkness of different area blocks, so that the dynamic effect of shadow flowing is achieved.
