Stage lights can be divided into three types according to the optical structure: floodlights, spotlights and slide lights; according to the positions installed on the stage, there are face light, slap light, foot light, column light, top row light, sky row light, ground row light and flow The division of light. Floodlighting system refers to lamps that can emit uniform and soft light and can illuminate lights in a certain direction. Individual floodlights, top row lights, footlights and curtain lights are generally used to illuminate the sky curtain, painting scenery or performance area. Condensing system refers to lamps that can emit orientation and control the range of light zones. Generally, the principle of refraction is used to project different light spots through the lens. If using thread soft light.
The lens can produce light spots with soft edges. A lamp that uses a reflective optical structure to achieve a condensing effect is called a stage light. The slide system is to add a set of objective lenses in front of the condensing lamp to project light and image. This kind of slides can be divided into: ① projection slides that use slide imaging; ② projection slides that cast clouds, water, fire and other moving images on the scene through a rotating disc-shaped chain belt; ③ use long focal length objective lens Make the small spot sharply image. A follow-up light that highlights the protagonist's image; ④A lamp with an ellipsoidal concave mirror called a modeling light.
The stage light control system must be able to effectively control and deploy all lamps and produce a harmonious artistic effect. It consists of three parts: power distribution board, dimmer and main console.
The stage light design is mainly based on the artistic conception of the script, the director's requirements and the overall design of the stage art, the drawing of the lighting design, and the specific arrangement of the technical embodiment. Lighting design should be able to use a variety of modeling methods to adapt to different styles of performances, if some performances require a realistic style, while others require the creation of abstract, freehand or metaphorical moods.
