What Is the Principle of Colorful LED Lamp Beads?

The full name of the LED is semiconductor emitting diode, which is made of semiconductor material. Its functional principle is to directly transform electrical energy to optical energy, and the electric number is transformed into a light signal light -emitting device. Its advantages are: low consumption, high brightness, rich color, strong vibration resistance, long service life (normal glowing reaches 80,000 to 100,000 hours), cold light source, etc., can be said to be real green lighting. The lighting products with LED as the new light source will definitely replace white weaving lights in the future of the 21st century, becoming another revolution in human lighting. LED lamp beads use low-voltage power supply, and the power supply voltage is kept between 2-4V. According to the difference in product, LED lamp beads are a high-voltage power supply than the application of high-voltage power, which is especially suitable for application in public places in public places. The composition of colorful LED lamp beads includes red (R), green (g), and blue (b) three -base color LED. Everyone is familiar with two -color LED. Usually consisting of red light LED and green LED. It can independently emit red or green light. If the red light and green light are highlights at the same time, the two kinds of light of red and green will be mixed into orange -yellow. The principle of discoloration of the discoloration lamp is when three basic LED lights up with two LEDs, it can emit yellow, purple, cyan (such as red and blue LEDs when lighting out of purple light); If the three LEDs of the blue light at the same time, it will produce white light. If there is a circuit that can light red, green, and blue light LED respectively, light up, and lit with three base colors alone, then seven different colors of light can be emitted, so the phenomenon of colorful LED lights appears.
