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.
