How to Light Up the Light Diode

How much do you know about glowing diodes? Today's light -emitting diode market demand is wide. Those who are used in street lights, medical devices, car lights, cameras, power indicator lights and other fields are all involved. Today, the editor mainly wants to explain how to light up the light -emitting diodes. Take the indicator light as an example; when our luminous diode is connected to AC 220V, it is used as a power indicator, and the simplest way is to connect a current -limiting resistor. According to the type of light emitting diodes the size of. The general light-emitting diode is 2.8-3.4V, the materials for various colors are different, and the voltage is different. Now the high brightness light emitting tube, the current 10mA is already bright enough. For general light emitting diode, the working current value is 1mA-15mA. The specific brightness can be changed by adjusting the size of the current limit resistance. The main principle of light emitting diode is actually to form a certain potential barrier through the end voltage of the PN knot. When the position of the positive bias voltage decreases, most of the carrier in the P area and the N area spread to the other party. Because the electronic migration rate is much greater than the air acupoint migration rate, a large number of electronic spreads to the P area, forming an injection of a minority carrier of the P area. These electrons are compounded from the cave on the price, and the energy obtained during composite is released in the form of light energy. This is the principle of PN knot glow. The above is some of the lighting explanations about the light emitting diode today, which is summarized by the editor.
