Detailed explanation of the differences and characteristics of floodlights, spotlights and effect lighting

1. Floodlights (diffusers or flat lights)
Floodlights are usually not equipped with lenses (except for floodlights). They mainly rely on the direct light from the light source and the refracted light from the curved reflector to form a directional lighting structure. However, some floodlights are designed for long-distance lighting. The direct light from the light source is concentrated into a powerful outgoing light through a lens. This is the uniqueness of floodlights. In addition, there are strip lights designed for comprehensive lighting, and separate lamps designed for local stage lighting. They can adjust the angle as needed to produce a softer and more uniform light effect.

Floodlights are known for their wide range of illumination and soft and uniform light characteristics. By equipping them with color filters, different colors of light can also be obtained. In stage lighting, floodlights are usually designed as row lights for large-area lighting needs. For local stage effect lighting, separate lamps with adjustable angles are used to precisely control the light. At the same time, within the scope of stage lighting, floodlights should avoid producing light spots and significant light spot edge marks to ensure the uniformity and aesthetics of the overall lighting.

2. Spotlights
The structure of the spotlight is ingenious. It can use a reflector to concentrate the light beam emitted by the light source to the front and freely project it to a local area of ​​the stage through a lens. The light flux and projection angle of the light can be flexibly adjusted, and the implementation methods include moving the light source and moving the lens. The spotlight is the basic equipment for stage lighting. Its optical system is centered on concave reflection and condenser, showing the characteristics of a light spot with bright center and clear edges. Compared with floodlights, its projection range is narrower, but it can flexibly adjust the light brightness within a limited area. Spotlights are widely used in various lighting occasions such as face light, slap light, side light, column light, top light, etc., to create a local projection effect for the stage.

In addition, spotlights can also be classified according to the edge shape of the projected light, including soft light spotlights, flat convex spotlights and contour spotlights. Soft spotlights emit soft light, suitable for creating a relaxing atmosphere; plano-convex lens spotlights have slightly stronger light and clear outlines, making them an important tool for stage lighting; and contour spotlights, also known as modeling spotlights, have a special structure that can strongly focus the light around the projection surface, making them an indispensable lighting device for tracking performers.

3. Effect lighting
Effect lighting is an indispensable lighting tool for modern stages. It can vividly reproduce natural phenomena such as rain, snow, clouds, waves, and flames, and can also add gorgeous effects to the background of songs, dances, and dramas. Unlike ordinary slide projectors, effect lighting devices are large in size and extremely bright, and can perform professional projections, becoming a unique landscape on the stage.
