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...

At present, although the demand for LED lighting in the market is still heating up, many large-scale lighting engineering orders have quietly shown signs of delay. The unprecedented size of the market has led to fierce competition among industry players. In some common areas such as home furnishings, roads, and engineering, the market share of products such as light bulbs and tubes is already minimal. In this situation, some manufacturers are trying to find their own way in the field of special lighting applications. LED invests in printing technology while still being environmentally friendly and energy-saving In recent years, as LED technology continues to expand, the increasingly severe environmental problems have raised people's awareness of environmentally friendly products, and LED printers have begun to receive attention. LED printing actually uses light-emitti...
