LED lamp beads general knowledge and application

LED English (light emitting diode), LED lamp beads are the English abbreviation of light-emitting diode, referred to as LED, which is a popular name. LED lamp beads are widely used in lighting lighting, LED large screen display, traffic lights, decoration, computers, electronic toys and gifts, switches, telephones, advertising, urban brilliance projects and many other production fields.
1.Brightness The brightness of LED is different and the price is different. LEDs used for LED lamps should meet the laser class I standard.
2.Antistatic ability LED with strong antistatic ability, long life, so the price is high. Usually LED with antistatic greater than 700V can be used for LED lighting.
3.Wavelength LED with consistent wavelength, consistent color, if the color is required to be consistent, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure colors.
4.Leakage current LED is a unidirectional emitter, if there is a reverse current, it is called leakage, LED with large leakage current, short life, low price.
5.Different uses of LEDs have different emission angles. Special angle of luminescence, higher price. If the full diffuse angle is full, the price is higher.
6.The key to different qualities is lifespan, which is determined by light decay. Small light decay, long life, long life, high price.
7.Wafer The emitter of LED is a wafer, and the price of different wafers varies greatly. Chips in Japan and the United States are more expensive, and the prices of chips in Taiwan and China are generally lower than those in Japan and the United States.
8.Wafer size The size of the wafer is indicated by the side length, and the quality of the large chip LED is better than that of the small chip. The price is proportional to the size of the wafer.
9.Colloidal ordinary LED colloids are generally epoxy resin, LED with anti-ultraviolet and fireproof agent is more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and fireproof.
