Classification of LED chipsLED chips can be classified by polarity into N/P and P/N. Divided into surface emitting type according to the emitting part (most of the light is emitted)Divided by emitting light from the surface of the chip) and five sided emission type (with more light emitted from the surface and sides). If divided by composition, it can be divided into binary, ternary, and quaternary LED chipsThe film. The so-called binary, ternary, and quaternary LED chips refer to the number of effective elements contained in the chip. If classified by constituent elements, it can be divided into the following categoriesType:A. Binary chips (phosphorus, gallium): H, G, etc. (with two effective elements)B. Three element chips (phosphorus, gallium, arsenic): SR, HR, UR, etc. (with three effective elements)C. Quaternary chips (phosphorus, aluminum, gall...

A complete list of reasons for dead LED chip lights. Many customers may find dead lights when using LED chip lights. Often, the engineering team has been searching for a long time but cannot find the problem. Hongcheng Optoelectronics Engineering provides the following points for everyone. If you encounter the following situations, you can refer to them:1. Generally, LED brackets are packaged using bracket bars, which are made of copper or iron metal materials stamped by molds. Due to the high cost of copper materials, the cost is naturally high. Influenced by fierce competition in the market, in order to reduce manufacturing costs, most markets use cold-rolled low-carbon steel to punch LED brackets. Iron bracket bars need to be silver plated, which has two functions: one is to prevent oxidation and rust, and the other is to facilitate welding. The electroplating ...

There are probably two situations where this problem occurs:1. Are your power plugs and sockets compatible and confirmed to be functioning properly? Please try replacing the plug or socket to check if the power supply is normal;2. If there is still a "flash", it may be a problem with the power driver. It is possible that the output voltage of the driver is not consistent with the driving voltage required by your LED strip (you can test whether it matches or understand the driving voltage required by your strip). It is also possible that the power driver is damaged internally. Please try replacing it with a matching driving power supply;Note: If your light strip is directly connected to 220V mains power and this problem occurs, it must be due to a broken AC to DC converter inside the high-voltage plug.LED strip lights require a DC constant voltage power supply.If eq...

There are several reasons for LED bead leakage:1. Excessive height and thickness of the base adhesive can cause electrical leakage.2. Improper process can cause chip cracking, such as excessive pressure on the magnetic nozzle during wire bonding due to improper operation of the wire bonding machine, resulting in chip damage and cracking.3. Static electricity causes leakage in lamp beads, which is usually caused by friction and is a relatively easy cause of leakage. Therefore, when producing lamp beads, employees should be required to wear anti-static clothing and hats to minimize the occurrence of static electricity.4. The chip itself has defects that cause leakage.5. Chip contamination is a common and frequent issue. The reason may be due to not paying attention when using the chip, which may cause the chip to be contaminated with dust or water vapor. LED chips are very sm...
