Knowledge of lighting control equipment

One, seven and full color

When it comes to color, it is necessary to understand the knowledge of the three primary colors. The three primary colors mentioned on our lamps are RGB, that is, red, green and blue. It belongs to the additive color mix, not the red, yellow and blue (subtractive color mix) that we commonly say. The changes of the three RGB color channels and their superposition with each other can obtain a variety of colors, which can be said to include almost all the colors that human vision can perceive. And they're superimposed on each other to get a variety of colors.

Seven colors: It is a simple mix of RGB three colors

Full color: Using the RGB model, the RGB component of each pixel is an intensity value in the range of 0-255. For example, the value of pure red R is 255, the value of G is 0, and the value of B is 0. Gray R, G, B three values are equal (except 0 ~ 255); The white R, G, and B are 255; Black R, G, and B are all 0.? RGB images use only three colors, so they can be mixed in different proportions, rendering 16,777,216 colors on the screen. In RGB mode, each RGB component can be assigned a value from 0 (black) to 255 (white). Columns such as bright red use R values of 246, G values of 20, and B values of 50. When all three scores are equal, a gray shadow is produced. When the values of all components are 255, the result is pure white; When the value is 0, the result is pure black.

Two, internal control and external control

Internal control: The control chip is inside the lamp, there is no need to connect the external controller, and the synchronous internal control needs to connect the AC power supply, and power on at the same time.
External control: Not all outer space lamps have no control chip inside. For external control, an external controller is required. Usually the function of the external control lamp is determined by the controller function.

Third, single controller and online controller

Single controller does not need to buy an additional computer, it has an SD card, CF card two, will you need to copy the program in the storage card, you can make the lamp according to the program mode light.
The online controller is to buy a computer connection, and the LED lamp can synchronize the display program with the computer.

Four, external control lamp pixels

Externally controlled linear lamps can generally be divided into 6 segments, 8 segments, 16 segments, 32 segments, a segment represents a pixel point, externally controlled pixel point light source and externally controlled projection light generally a lamp a pixel point, segmented control.
