First, the effect of lighting

      Effect lighting is a lighting apparatus that expresses rain, snow, clouds, waves, and flames. It can also illuminate the background of song and dance dramas. It is a very important lighting means for the modern stage. The effect luminaire is different from a general slide projector. Its volume and brightness make it possible to perform projection. It is a stage-specific projection device.

      Second, floodlights (scattered or flat light)

      Floodlights generally do not have a lens (except floodlights), but instead use direct light from a light source and light from a curved surface to make it have a directional structure, but also as a long distance. Lighting floodlights, which direct light from the light source by the lens and emit light, this is the cast floodlight. In addition, there is a wider range of bar lights designed for all lighting, and the effect of creating a more effective soft light for the part of the stage, or adjusting the angle of the curved surface so that the surface can be adjusted uniformly Lighting stage lighting.

      Floodlights have a wide range of illumination, soft and uniform light, coupled with filters to obtain other colors of light. Floodlights for stage lighting are generally designed as a row of lights for large-area lighting. Local effects lighting on the stage, with individual luminaires with adjustable angles. Floodlights must not have spots and noticeable spots on the edges of the stage lighting.

      Three spotlights

      The structure of the spotlight is that the light beam emitted from the light source can be focused to the front using a mirror. The Guangzhou stage light can freely cast light to the local area of ＆#8203;＆#8203;the stage through the lens. The light can pass through and the projection angle can be adjusted. The adjustment method includes a moving light source. Both type and mobile lens type.

      Spotlights are the basic lighting fixtures for stage lighting. Its light system is mainly composed of concave reflectors and condenser mirrors. Its characteristic is: Its light spot is bright in the middle, the edge is clear, its light projection scope is narrower than the floodlight, can adjust the light intensity in the light projection scope. The adjustment is divided into two types, the light source moving type and the lens moving type, and the local light projection effect is obtained by adjusting the change of the illumination intensity of the light emitting surface. Condenser is generally used in surface light, ear, side light, column light, top light, etc., and is currently used in stage lighting.

      According to the edge shape formed by casting light, spotlights can be roughly classified into three types: soft spotlights, plano spotlights and profile spotlights.

      1, outline spotlight (styling spotlight)

      The structure of this projector enables the light around the projection surface to be strongly focused. Guangzhou stage lighting is an indispensable spotlight for tracking performers. It differs from other spotlights in that it has two lenses, and it also incorporates a Guangzhou stage light-cutting plate that can change the size of the light projection area and change the shape of the cast light.

      2, soft spotlights

      The soft spotlight of the emitted light is a light fixture in the spotlight that is soft and light. Fresnel lens spotlights are commonly used.

      3, plano-convex lens spotlights

      The nature of light is stronger than soft light, although the outline is also clear, but it is not focused light like a contour spotlight, because it is more difficult to express it from the quality of light, so it is generally referred to as a plano-convex spotlight according to its structure. It has now become the main lighting fixture for stage lighting and is essential on the stage.
