Soft light: the light is soft and well-proported, which can highlight a certain part, but also has no hard light spot, so that it can be connected with several lights, and the common ones are 0.3KW, 1KW, 2KW, etc. It is mainly used for the close optical position of column light and flowing light.
3, back light: it is a kind of reflection type lamps and lanterns, its characteristic is light quality, high intensity of illumination and range far, is an economic and efficient floodlights, common main have 0.5 KW, 1 KW, 2 KW, etc., with 2 KW.
4, diffused light: the light is diffuse, say, the projection area is large, divided into days of astigmatism and astigmatism, common are 0.5 KW, 1 KW, 1.25 KW, 2 KW, etc., more than for a canopy light, also can be used in the theatre stage lighting.
5. Modeling lamp: the principle is between the lamp and the spotlights. It is a special kind of lamp, which is mainly used for the shape projection of characters and scenery.

9, this is a kind of controlled by DMX512 or RS232 or PMX signals intelligence lamps and lanterns, the light color, light, intensity of illumination is superior to the above general lamps and lanterns is in recent years, developed a kind of intelligent lamps and lanterns, often installed on the surface light, top light, stage after the steps such as position, color, shape of its operation, figure, etc all can run the program. Due to different power sizes, there is a difference in use on the stage. General small power computer lamp, only suitable for ballroom use.
