RGBLED Light 4 Tube Feet Are far More Important Than You Think!

Ordinary emitting diodes (LED lights) are only two tube feet, one long foot and one short foot, of which the long foot is connected to the power supply, and the short foot is connected to the power supply. Is there a LED light with four tube feet? There are really such RGBLED lights in the market. Since the two feet are enough, why have there four feet? The manufacturer will take you to further interpret it. Don't look at his four tube feet. In fact, there are three RGBLED lamps, one of which is the public part of three LED lights, and the other three feet are the second tube of each LED light. The lamp also has a common cathode and common anode. For RGBLED lamps with common anode, the long tube of the four tube feet is anode, that is, the positive electrode of the power supply. On the anode, the black table pen is exposed to any of the other three tube feet. If this LED light is normal, you will also see that this LED light is light, and the voltage drop will appear on the multimeter. Ordinary LED lights, the results of the presentation are not different. After the LED lamp is electric, the red light is emitted. If the red table is motionless, the black table pen is exposed to the other two tube feet, and you will find that there will be light of other colors. In addition to red and green and blue, this is why is it called it called The reason for his RGB LED light, where R represents red, comes from the first letter of the English word Red (Chinese meaning: red); G represents the green of the English word Green (Chinese meaning: green) the first letter; It is blue, from English word BLUE (Chinese meaning: blue) first letter. If you look at the pressure drop during the measurement process, you will find that different colors of light will be emitted, and the pressure drop will be different. From the picture above, you can also see. In practice, the light of these three colors is also the three primary colors of light. If the two colors of the LED lights are lit at the same time, the light of other colors can be emitted, such as the red and green LED lights to light up at the same time. When a LED light is lit at the same time, a compound light will be emitted: white light. The designed four -legged RGBLED lamp also has his benefits. After controlling these four tube feet, you can control the LED lights to send a variety of colors of light. Of course, it is definitely very troublesome to control it. Over. Of course, you can also detect the quality of the RGBLED light with this method. If you find that some colors (three types of red and blue) are found during the detection process, then the LED light that emits the color is likely to break down For individuals, it is not possible to repair it. It needs to be replaced. The manufacturer specializes in the production of RGBLED lamp beads, patch RGB, and plug -in RGB production.
