What kinds of lighting effects are there on the stage?
According to the optical structure, stage lamps can be divided into floodlights, spotlights and sliding lights. According to the components installed on the stage, there are surface light, palm light, foot light, column light, top light, skylight, terrestrial light and streamer.

1, floodlighting system refers to the lamps that can emit uniform and soft light and illuminate a certain direction. Independent floodlights, ceiling lights, footlights and curtain lights are usually used to illuminate the sky, painting scenes or performance areas.

2. Concentration system

A lamp that can emit directions and control the range of light areas. Generally, different light spots are projected through the lens by using the refraction principle. If a threaded soft lens is used, a light spot with a soft edge can be generated. A lamp that uses a reflective optical structure to achieve the condensing effect is called a return light.

3. Sliding system

Add a set of objective lenses in front of the spotlight to make it project light and images. This kind of slides can be divided into: ① projection slides imaged by slides; (2) Slide projector, which projects moving images such as clouds, water and fire onto the scenery through the rotating disc chain belt; ③ Use a long focal length objective lens to clearly image small spots. A spotlight that highlights the image of the protagonist; (4) Ellipsoidal concave mirror lamp is called modeling lamp.
