If you want to do a good job in the configuration of professional stage lights, you must first understand the common light positions of stage lights. This is an important part of the correct selection of configuration. 1. Surface light: The light projected from the front of the audience to the stage, mainly used for the front lighting of the characters and the basic light spreading and dyeing of the stage.

2. Slap in the face: Located on both sides of the stage, the light obliquely cast on the stage is divided into upper and lower layers. It mainly assists surface light, strengthens facial lighting, and increases the three-dimensional effect of characters and scenery. 3. Column light (also known as side light): The light projected from both sides of the stage is mainly used for lighting the two sides of characters or scenery to increase the sense of three-dimensionality and outline. 4. Top light: The light projected from the top of the stage to the stage is divided into one row of top light, two rows of top light, and three rows of top light from front to back. It is mainly used for general lighting of the stage to enhance the illumination of the stage.

At the same time, there are many fixed-point lighting of scenery and props, which are mainly solved by top lighting. 5. Backlight: The light projected from the opposite direction of the stage (such as top light, bridge light, etc.) can outline the outline of characters and scenery, enhance the sense of three-dimensionality and transparency, and can also be used as a specific light source. 6. Bridge light: The light projected on the stage from the flyovers on both sides of the stage is mainly used to assist the column light and enhance the three-dimensional effect.

7. Foot light: The light projected from the platform in front of the stage to the stage, mainly assists the surface light illumination and eliminates the shadows formed by the face and jaw of the characters illuminated by high positions such as surface light. 8. Sky and earth lighting: the light projected from the top and bottom of the sky to the sky, mainly used for lighting and color changes of the sky. The ones used now are generally 1200W-1500W/pcs. 9. Flowing light: located on the flowing light stand on both sides of the stage, it mainly assists the bridge light and supplements the light on both sides of the stage or other specific lights.

10. Chasing light: The light position required from the auditorium or other positions is mainly used to track the performance of actors or highlight a specific light, and it is also used for the host. It is a close-up pen of stage art and plays a finishing touch. Generally, there are 575W type, 1200W type, 2500W type, 4000W type. The promotion of the design of the color changer greatly simplifies the number of stage lamps, reduces the labor intensity of the lighting workers, and saves the investment amount. Therefore, it is an indispensable device for the current stage configuration. At present, there are mainly mechanical There are two kinds of color changer and motor color changer.

1. Stage mechanical color changer: It is simple in design and low in price. It was the mainstream product in the mid-1980s and 1990s, and it is now close to being eliminated. 2. Stage computer color changer: It is a new type of color changer developed in recent years. It adopts international standard DMX-512 signal output, can be controlled by a dedicated controller, and can also be connected to a computer dimming station. It has many Mode, high precision, large capacity, long control distance and other characteristics, it has become the mainstream product of color changer in the current market. At present, dimmers in the market mainly include analog dimmers and digital dimmers, and their characteristics are: 1. Analog dimmers: use analog dimming technology, and the output signal is 0-10V one-to-one output.

Generally, analog dimmers have a simple design, fewer controller circuits, and poor dimming curves, but the market price is relatively low, and they are easy to learn and master. They were mainstream products from the late 1970s to the mid-1990s. The common ones are 3-way, 6-way, 9-way, 12-way, 18-way, 24-way, 60-way, 120-way, etc. The power of each line is mostly 8KW, but there are also 2KW, 4KW, etc. Most of the small lines are integrated machines, and the large roads The number is a split machine. 2. Digital dimmer: use audio chip technology, DM512 digital signal.

Digital dimming consoles are easy to use (especially for large circuits), and their dimming function, backup function, grouping function, dimming curve, etc. are superior to analog dimming consoles, and their performance and price are also reasonable, so they are very popular among users. The common ones are 12 roads, 36 roads, 72 roads, 120 roads, 240 roads, 1000 roads, etc., and each road is mostly 2KW, 4KW, 6KW, 8KW, etc. After understanding the lamp position, lamp characteristics, control equipment and color changer, you can design the correct use plan according to the respective characteristics, the size of the use scale, the complexity and simplicity of the lamp, and adapt measures to local conditions.
