The group arrangement of stage and dance floor lamps and the selection of light control equipment are a key issue in the combination of art and technology.

1. Lamp marshalling

Before grouping, it is necessary to classify the selected lamps. When grouping, it is mostly considered from the artistic conception, such as color matching, light distribution, and what kind of atmosphere is suitable for expression, etc., and then the lights (or colors) that are suitable for simultaneous lighting ) Is grouped in parallel, and controlled by a switch (or a group of contacts of the light console or the light machine). Safety issues must also be considered when marshalling. Technically, through calculations, ensure that the total current (power) of the lamps in parallel cannot exceed the rated current value of the control switch or contact. Practice has proved that in medium and small dance halls, if the lighting group can reach a dozen or 20 groups, it can have strong expressiveness and variability; large dance halls and theaters, due to complex stage lighting, are often used Only dozens or even hundreds of lighting groups can meet the requirements.

2. Selection of light control equipment

Commonly used lighting control equipment in song and dance halls includes power switch, multi-channel switch board (such as 12 channels), light machine (such as 4 channels), multi-channel program console (such as 16-channel light console), multi-channel dimming console (such as 24-channel dimming console) and circuit light controllers specially matched with computer lighting. They have their own characteristics and are suitable for controlling different types of lamps and for different occasions.

The power switch has good arc extinguishing and protection performance. The rated current ranges from 10A, 15A, 20A, up to several hundred amperes, forming a series. When the power switch is not frequently turned on and off, it is mostly used as a master switch or area switch, such as a dance floor, stage light master switch, air conditioner, exhaust fan master switch, and some infrequent operation effect lights (such as follow-up lights, neon lights, Group computer light) switch.

The rated power of each channel of the multi-channel switch board is generally 1500-2000W. It is suitable for controlling all kinds of lamps with changing functions, such as all kinds of turning lights, voice-activated lights, and all kinds of lamps that do not need to be operated frequently (such as purple tubes, hoods, etc.). The multi-channel light machine is actually a simple program controller, suitable for controlling some lamps that change according to a fixed program cycle, such as string lights, snake tube lights, rainbow hose lights, and decorative lights that are lit in groups on the stage ladder, etc. .

The light console has multiple functions such as manual inching (light touch switch), program control, and voice control, so it is widely used in various entertainment venues from low to mid-range to high-end. The jog function of the light console can be used to replace the combination switch board to control various lamps that have changing functions and do not need to be operated frequently. The program control and voice control functions of the light console can be used to control some lamps that do not have the function of change, and only rely on external control equipment to produce the change effect, such as "rain light" groups with different patterns and different colors. It is worth noting that the program control function should not be used to control various rotating lights, scanning lights, strobe lights, and other lamps that have a rotating change function.

The dimming console is a higher-grade program control console. In addition to the on-off control function, it also has a number of thyristor dimming functions, so it is also called a multi-channel dimming console/usually using its dimming function to control the stage, Part of the dance floor needs to be dimmed, but does not have lamps with changing functions in order to create a different atmosphere.
