Some of the latest Light Emitting Diode (LED) technology puts the equivalent of a separate red, green and blue light source into what looks like one bulb. By varying the intensities of the red, green and blue sources, the bulb appears to change color. They’re called RGB LEDs. Start thinking of the possibilities. You create the final color by controlling the individual brightness of red, green and blue. That’s three control channels and it’s typically called a pixel. and we make a beautiful gate with pixel for more attractive. we believe in innovation.
