According to the optical structure, the stage lamps can be divided into three categories: floodlights, spotlights and slides; according to the parts installed on the stage, there are face light, slap light, foot light, column light, top row light, sky light, ground light and flow. The division of light. A floodlight system is a luminaire that emits evenly soft light and illuminates a certain direction of light. Individual floodlights, overhead lights, foot lights, and curtain lights are commonly used to illuminate skylights, painting sets, or performance zones. A concentrating system is a luminaire that emits orientation and can control the extent of the zone. Generally, the principle of refraction is used to cast different spots through the lens. For example, a threaded soft-light lens produces a soft spot on the edges. A lamp that uses a reflective optical structure to achieve a concentrating effect is called a backlight. The slide system is to add a set of objective lenses in front of the spotlight to make it project. This kind of slide can be divided into: 1. shooting slides using slide imaging; 2. shooting slides that cast cloud, water, fire and other activity images on the scene through the rotating disc chain; 3. The long focal length objective lens provides a clear image of small spots. A follow-up light that highlights the protagonist's image; 4. An ellipsoidal concave mirror is called a luminaire for modeling lights.
The stage lighting control system must be able to effectively control and deploy all the luminaires and produce a harmonious artistic effect. It consists of three parts: power distribution board, dimmer and total console.
The stage lighting design mainly carries out artistic conception according to the overall idea of the script, the director's requirements and the stage art, draws the layout design, and arranges the technical embodiment work. Lighting design should be able to use a variety of modeling methods to adapt to different styles of performance, such as performance requirements to show a realistic style, while others require the creation of abstract, freehand or metaphorical mood.
