Hello everyone, I am a dream. Today, let ’s introduce the problem of the composition of LED lamp beads for 4LED lamp beads. Here are a dream to summarize this issue and related issues. Let’ s take a look. Catalog of the article: 1. What are the composition of LED lamp beads 2. What are the internal structure of LED lamp beads? What are the composition of LED lamp beads? It is a diode with blue light or ultraviolet light, plus fluorescent powder with red or yellow or green light. Its use is widely used, such as lighting (family, flashlight, back investment, etc.), digital display (date, time, temperature, etc.), animation display (large screen TV) and so on.
LED lamp bead composition LED means glowing diode, English lightingDiode. It is a diode with blue light or ultraviolet light, plus fluorescent powder with red or yellow or green light. Its use is widely used, such as lighting (family, flashlight, back investment, etc.), digital display (date, time, temperature, etc.), animation display (large screen TV) and so on.
LED lamp bead's internal structure introduction LED lamp beads are mainly composed of five materials: bracket, silver glue, chip, gold thread, and epoxy resin.
LED lamp bead bracket 1. The role of brackets: conductivity and support 2. The composition of the bracket: The bracket is formed by the electrophus -plated material, from the inside to the outside, the material, copper, nickel, copper, and silver five. Composition of the layer. 3. Types of brackets: Bring a cup bracket for a concentricity type, and the flat head bracket is used as a large angle of astigmatism. LED Lighting Silver Plane 1. The role of silver gum: fixed chip and conductivity. 2. The main ingredients of silver glue: silver powder accounts for 75-80%, Epoxy (epoxy resin) accounts for 10-15%, additives account for 5-10%. Public account: Shenzhen LED Network 3. Silver rubber use: refrigerated, you need to thaw and stir well before use, because the silver gum is placed for a long time, the silver powder will precipitate. Essence
LED light principle and composition A light -emitting structure is the lamp beads in the size of the lamp. Although its size is small, it has the Qiankun inside. After amplifying the structure of LED lamp beads, you will find a chip that is shaped like a sesame size. This chip structure is extremely complicated. It is divided into several layers: the top layer is called the P -type semiconductor layer, the middle layer is a luminous layer, and the bottom layer is called the N -type semiconductor layer.
2 Overlooking principle From the perspective of physics: When the current is through the chip, the acupoints in the electron and P -type semiconductor in the N -type semiconductor are severely collided in the luminous layer to produce photons. (That is, the light that everyone sees) The light -emitting diode LED is also called the glow diode. Its volume is very small and fragile, which is not convenient to use directly. So the designer added a protective shell to it and sealed it in it, which constitutes an easy -to -use LED lamp bead. After combining many LED lamp beads, it can form a variety of LED lights. LED lamp four tube feet mean LED lamp Four pipes are generally so -called full -color lamp beads. It is encapsulated with three different colors of light -emitting diode, which can emit three lights of red, blue and green, respectively. Essence The negative electrodes of the three emitting diode are connected together, and the positive poles are independent of each other, so there are four electrodes in total, which is often said that there are four feet. You can control the current of the three luminous diode through the controller to display different colors. The above is the answer to the composition and related questions of the 4LED lamp beads for composition of LED lamp beads. I hope it will be useful to you [Responsible editor: a dream] |
