Fabrication method and principle of LED star light

The production of monochrome light string includes monochrome light string plug-in and wiring. The plug-in and wiring of monochrome light string are very simple. When inserting, the light string can be inserted into the corresponding hole. When wiring, it should be connected in a certain order.
At the same time, pay attention to the positive and negative poles of all lamp strings, and ensure that they are together as much as possible. Connect the positive poles together and then lead out the positive wire. Similarly, connect the negative poles together to lead out the negative wire.
The wiring of the LED light string shall be tested, all the light strings shall be lit, all the lines shall be tied up separately and kept fixed, and then the wiring part shall be coated with waterproof glue, so that the production of the LED light string is completed.
When electrons and holes recombine, they can radiate visible light, so they can be used to make light emitting diodes. It can be used as an indicator light in circuits and instruments, or as a text or digital display.
LED lamp string: gallium arsenide diode emits red light, gallium phosphide diode emits green light, silicon carbide diode emits yellow light, and gallium nitride diode emits blue light. Due to its chemical properties, it can be divided into organic light-emitting diode (OLED) and inorganic light-emitting diode (LED).
