The principle and advantages of RGBLED lights

RGBLED lights are composed of three colors: red, green, and blue. In addition, there are blue LED and yellow fluorescent powder, as well as ultraviolet LED and RGB fluorescent powder. Some LED backlight boards have particularly clear and bright colors, and even have high-quality televisions, which is a characteristic of RGB. Red is red, green is green, and blue is blue. In the mixed colors of light, there are more diverse characteristics.

RGB is designed based on the principle of color luminescence. Generally speaking, its color blend is like three lights: red, green, and blue. When their lights overlap with each other, the colors are mixed, but the brightness is equal to the sum of the brightness of the two. The higher the mixing brightness, the additive mixing. The characteristic of additive mixing is that the more overlays there are, the brighter the brightness.

The red, green, and blue color channels are divided into 256 levels of brightness for each color. The “light” at 0 points is weak – off, and the “light” at 255 points is on. When the three color grayscale values are the same, different grayscale values are generated, that is, the three color grayscale is 0, which is a dark black tone; The three color grayscale is 255, which is a bright white tone.

RGB color is called additive color because you refer to it as additive color because adding G and B together (i.e. all light reflects back to the eye) can produce white. Additive colors are used for lighting, television, and computer displays. For example, a display generates color by emitting light through red, green, and blue phosphors. The vast majority of visible spectra can be represented as a mixture of red, green, and blue (RGB) light in different proportions and intensities. If these colors overlap, they will produce cyan, magenta, and yellow.

Currently, most monitors use RGB color standards. On the monitor, it generates colors on the red, green, and blue LEDs on the screen through electronic preferred, exclusive, exclusive formula, first release, nationwide first release, online exclusive, first release, national sales champion, national level product, and national leaders. Currently, computers can generally display 32 colors, with over 10 million colors available.

All colors on the computer screen are mixed in different proportions of red, green, and blue. A set of red, green, and blue is a small display unit. Any color on the screen can be recorded and expressed through a set of RGB values. The LED field adopts a three in one dot matrix full color technology, where RGB three color chips form full-color pixels in the emitting unit. With the continuous maturity of this technology, LED display technology will bring people a richer and more realistic color experience.

The eight advantages of RGBLED:

1. Stability: 100000 hours, with an initial 50% light attenuation.

2. Response time: The response time of incandescent lamps is in milliseconds, while the response time of LED lamps is in nanoseconds.

3. Environmental pollution: No harmful metal mercury.

4. Voltage: The LED beads use a low-voltage power supply, with a power supply voltage between 2-4V. Depending on the product, it is a high-voltage power supply; A safer power source, especially suitable for public places;

5. Current: The working current is 0-15ma, and the brightness varies with the increase of current

6. Efficiency: Incandescent lamps with the same light efficiency consume 80% less energy.

7. Applicability: Very small, each unit’s LED chip is a 3-5mm square, so it can be made into various shapes of equipment, suitable for changing environments.

8. Color: Changing the current can change the color, and light-emitting diodes can easily adjust the structure and gap of materials through chemical decoration methods, achieving multi-color luminescence of red, yellow, green, blue, and orange. For example, when the low current is a red LED, as the current increases, it can turn orange, yellow, and finally green.
