舞台常规灯具
Conventional stage lamps
舞台灯具可分为三大类：泛光灯，聚光灯和效果灯。
Stage lamps can be divided into three categories: floodlights, spotlights and effect lights.
1． 泛光灯（散光灯或平光灯）
1. Floodlight (astigmatic light or flat light)
泛光灯的构造它一般不设置透镜（除投光泛光灯外），而是利用从光源来的直射光和从曲面反射板来的反射光，使其具有制向性的结构。但也有那样作为远距离照明用的泛光灯，它将光源直射光由透镜聚光而射出光线，这就是投光泛光灯。此外，还有范围更广的为全部照明而设计的条灯，和为舞台的局部造成更有效果的柔和的光线，或为使曲线面有均匀的照明而能调节其角度等需要而设计的单独灯具。泛光灯具有照明范围广，光线柔和和均匀的保定平面设计培训 保定空调维修 保定管道通风 包装盒定做 化粪池模具 废旧电缆回收 不锈钢铸件 特点配上滤色片可获得其他颜色的光。舞台照明用的泛光灯一般设计成一排灯，进行大面积照明。舞台的局部效果照明，采用可调角度的单独灯具。泛光灯在舞台照明的范围内不能有光斑和显著的光斑边缘痕迹。
The structure of floodlight generally does not set a lens (except the projection floodlight), but uses the direct light from the light source and the reflected light from the curved reflector to make it have a directional structure. But there are also floodlights for long-distance lighting, which focus the direct light of the light source by the lens and emit light, which is the projection floodlight. In addition, there are a wider range of strip lamps designed for all lighting, and separate lamps designed to create more effective soft light for parts of the stage, or to adjust the angle for uniform lighting on the curved surface. Floodlight has the characteristics of wide illumination range, soft and uniform light. With color filter, it can obtain light of other colors. Floodlights for stage lighting are generally designed as a row of lamps for large-area lighting. The local effect lighting of the stage adopts independent lamps with adjustable angle. The floodlight shall have no spot and significant spot edge traces within the range of stage lighting.
