Stage Lighting Color Changer
The design and promotion of the color changer greatly simplifies the number of stage lamps, reduces the labor intensity of lighting workers, and saves the investment amount, so it is an indispensable equipment for the current stage configuration. At present, there are mainly mechanical Color changer and electric and color changer two.
1. Stage mechanical color changer: Its simple design and low price are the mainstream products in the mid-1980s and 1990s, and are now close to being eliminated.
2. Stage computer color changer: It is a new type of color changer developed in recent years. It adopts the international standard DMX-512 signal output, which can be controlled by a dedicated controller or connected to a computer dimming console. Mode, high precision, large capacity, long control distance and other characteristics, it has become the mainstream product of color changer in the current market.
Lighting Control Equipment
1. Analog dimmer: Using analog dimming technology, the output signal is 0-10V one-to-one output. Generally, analog dimmers are simple in design, with few controller circuits and poor dimming curves, but with low market prices and easy to learn to 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 road is mostly 8KW, but there are also 2KW, 4KW, etc. The number is a split machine.
2. Digital dimmer: Using single chip technology, it is DM512 digital signal. Digital dimming consoles are easy to use (especially large loops), and their dimming functions, backup functions, grouping functions, and dimming curves are superior to analog dimming consoles, and their performance and price are relatively reasonable, which is very popular with users. Common ones are 12, 36, 72, 120, 240, 1000, etc., each of which 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 local conditions according to their respective characteristics, the size of the use scale, and the complexity of using lamps.
