1. DMX (Digital Multiplexing)
Data multiplexing is a programming protocol commonly used in lighting products. This protocol includes 512 channels, each with 256 values. Usually, a single channel is used to control the function of an automated lamp.
2. 8-bit DMX
DMX control channel parameters.
3. 16-bit DMX
A parameter that uses two DMX control channels, usually used for fine adjustment of horizontal and vertical control.
A term used to describe the light beam projected by the lamp in the air.
The motion effect of a programmed automated light looks like these lamps move randomly in a defined area.
A button on the light console that can generate an action when pressed and released. Also known as point control keys.
6. Digital Light
A Digital lamp, a kind of remote control lamp, uses a non-mechanical (usually video output) way to create and change the lamp output.
Dimmer, a device used to control the brightness of incandescent lamps.
Fly out and program the movement of the automated lighting fixture moving vertically from one position to another. For example, a typical FLYOUT CUE is to move the light beam from the stage to the audience area.
The luminous flux of lamps with the same power may be completely different because of their different light effects. For example, ordinary lighting bulbs are only 101m/W, while metal halogen lamps can reach 801m/W.
9. Color temperature
Color temperature means that the color emitted by the light source is the same as the color of the light radiated by the black body at a certain temperature. The temperature of the black body is called the color temperature of the light source and is generally measured in Kelvin. For example, 3200k and 5600k. The color temperature is high and the color of the light is cold: the color temperature is low and the color of the light is warm: when the color temperature is moderate, the light is close to white. Under normal sunlight in nature, the color temperature of light is generally higher than that of artificial lamps. Normally, the color temperature of sunlight is about 5600k, while the color temperature of the studio and performance lamps is about 3200k. (Thermal light source). However, the recent cold light source lighting in TV studios is a transformation of traditional light sources. The cold light source has a high color temperature, low energy consumption, and low heat generation. When performing indoor and outdoor photography, the color temperature conversion is simple and the picture is natural. Of course, the cold light source has higher performance requirements for the dimmer.
In modern light control, a new concept of the channel has been created. It refers to a collection of control loops on a fixture. Specifically: the functions of a certain lamp need to be controlled separately (for example focusing, strobe, color change, etc.), and the collective output circuit of the dimmer station is the channel.
