When it comes to LED beads, I believe many people know what they are used for. In other words, LED beads are actually made by using semiconductor materials to produce light-emitting diodes. They are a type of luminous device that directly converts electrical energy into light energy and electrical signals into light signals. The most important thing in the use of LED bead mounting beads is heat dissipation. Depending on the manufacturer of the beads, different packaging adhesives are used. In the early stage of baking, attention should be paid to timing and temperature, and in the later stage, attention should be paid to the mounting temperature. However, many people do not know the principle of bead luminescence. Below is our analysis of the principle of bead luminescence: The terminal voltage of the PN junction forms a certain potential barrier, and when a forward bias voltage is applied, the potential barrier decreases, The majority of charge carriers in the P and N regions disperse towards each other because the electron mobility is much higher than the hole mobility, resulting in a large number of electrons dispersing into the P region, forming an injection of a small number of charge carriers into the P region. These electrons recombine with holes in the valence band, and the energy obtained during recombination is released in the form of light energy. This is the principle of lamp bead luminescence. When the current passes through the wire and acts on the chip, electrons and holes are pushed into the quantum well, where electrons and holes recombine and then announce energy in the form of photons. This is the principle of luminescence, and the wavelength of light is also determined by the color of light, which is determined by the data forming the P-N junction. In addition, there are currently two latest planning concepts for lamp beads: 1. Emotional lighting: lighting fixtures are designed according to human needs. Emotional lighting starts from human emotions and creates an artistic lighting environment from a human perspective. Emotional lighting includes four aspects: environmental protection and energy conservation, health, intelligence, and humanization. 2. Situational lighting: It is the planning of lighting fixtures based on the needs of the environment. Situational lighting starts from the place and aims to create a beautiful and splendid lighting environment to enhance the scene effect and make people feel the atmosphere of the scene. Of course, attention should be paid to timing and temperature, and in the later stage, attention should be paid to the temperature of the patch. This is the principle of light emitted by the lamp beads, and the wavelength of light is also the color of light.
