[0049] During use: The outer wall of the first lamp cover plate 6 is a frosted surface, which can scatter the light emitted by the lamp core, so that the light will be very soft and will not stimulate the eyes of the user. Artificial crystal is actually made by mixing and firing sand, potassium carbonate, glass chips and at least 25% lead oxide. These crystals or glasses are first cut into small pieces and then polished. The more cut surfaces are ground, the greater the ability to refract light. The main polished shapes are: pear shape, semi-pear shape, star shape, button shape, spherical shape, rhombus shape, heart shape, octagon shape, cone shape, flower shape, trapezoid shape, etc., so that the crystal lamp will look shiny and very beautiful. In the initial state, the first lamp cover plate 6 will be closed and the second lamp cover plate 7 will be unfolded. When the user needs to switch the unfolding and closing states of the first lamp cover plate 6 and the second lamp cover plate 7, the servo motor 85 can be started to drive the second turntable 82 to rotate.
