What are the classifications of spotlights?

1. spotlight-the spotlight used on the stage refers to the use of a plano-convex condenser in front of the lamp. This kind of lamp can adjust the spot size, and the emitted music beam is relatively concentrated, with a small ratio of diffused light beside it. The power varies from 0.5W to 5KW, and the focal length is divided into long, medium and short. The visual distance can be selected as required. 2. rib light-or soft light, but in the TV industry, this is called spotlight. On the stage, in order to distinguish the scattering and softness of the above-mentioned plano-convex spotlight, it has a large diffusion area. Sometimes in order to control its diffuse light, a cover is added in front of the mirror to block it all. It is characterized by large light receiving area, not obvious flare feeling like spotlight, short shooting distance, power 1KW, 2KW, etc. 3. Backlight-There is no lens in front of this lamp, and the light is completely emitted from the larger reflector at the back. The same 2KW bulb is brighter than a spotlight, so it should be used when showing strong light source and brightness on the stage. Its effect is better than other lamps, and its characteristic is strong light beam. However, attention should be paid to the focus when dimming, and it is not appropriate to adjust the focus on colored paper or curtains, which may easily cause burning. In addition, the black center often appears in the center of dimming. In order to avoid the black center, an annular baffle is added in the center of the front end of the lamp, which makes the emitted light spot very large and difficult to gather. Now, a new type of cold light super spotlight has been developed, which is coated on the reflective bowl to make the outside line transmit backwards to reduce the temperature in front of the lamp, and the use effect is very good. In fact, the structure of the lamp is the same as that of the return light. 4. Imaging lamp-or modeling lamp, oval spotlight. The beam angle has many applications and can be selected as needed. Its main feature is that it can cut the light spot into various shapes such as square, diamond and triangle. Such as slides, or project the required patterns. Power is also available in optional configurations such as 1KW and 2KW. 5. Simple lamp-also known as PAR lamp, or beam lamp, its structure is to install a mirror bulb in the cylinder, and also install a tungsten bromide bulb with a reflective bowl. Its main feature is that it emits a relatively fixed beam with various beam angles and the spot size is not adjustable. 6. skylight-high-power astigmatism lamp, used to illuminate the sky from top to bottom. Bright and balanced light and large irradiation area are required. 7. Floor lamp-high-power astigmatism lamp, which is used to be placed on the stage surface. The lower part of the ceiling shines upwards, which is connected with the light irradiated by the ceiling lamp and evenly distributed up and down. 8. Astigmatism with lights-long strip, divided into multiple grids, generally can be divided into three or four colors. The power of each incandescent bulb is about 200W, which requires various colors to be connected by themselves. It can be used for large-area lighting curtains or painting curtains, and can also be used for large-area balanced lighting. All colors can also be used at the same time to produce beams of different colors. 9. General astigmatism lamps, such as iodine tungsten lamp and ordinary floodlights, are mainly used to uniformly illuminate a certain area or some scenery.
