Spotlight on the stage lighting of the basic lighting, its light system is mainly composed of concave reflection and condenser. Its characteristic is: its spot middle is bright, the edge is clear, its projection light range is narrower than the floodlight light, can adjust the light intensity in the projection light range. The regulation is divided into two kinds of light source moving type and lens moving type, and the local light effect can be obtained by adjusting the illumination change of the smoothness.
