0603 patch light-emitting diodes: colors are red, yellow, green, blue, etc.; the brightness of o603 patch light-emitting diodes can be customized by LED lamp beads manufacturers. Many customers think that the higher the brightness, the better. In fact, it is better to choose the brightness that suits your product according to your needs. Some products use too bright LED light-emitting diodes, such as children's toys and LEDs. Too high light-emitting diode brightness is not good for children's eyes. The following expands the 0603 patch light-emitting diode selection techniques organized by LED lamp bead manufacturers:
1. The brightness of the LED is different, and the price is different. The LED used for LED lamps should meet the laser grade standard.
2. The LED with strong antistatic ability has long life and high price. Normally, only LEDs with antistatic electricity greater than 700v can be used for LED lighting.
3. LEDs with the same wavelength and wavelength have the same color. If the color is required to be the same, 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 conductive light-emitting body. If there is a reverse current, it is called leakage. LEDs with large leakage current have short life and low price.
5. LEDs with different light-emitting angles have different light-emitting angles. Special lighting angle, higher price. Such as full diffusion angle, the price is higher.
6. The key to different quality of life is life, and life is determined by light decay. Low light decay, long life, long life, high price.
7. Chip LED's light-emitting body is a chip, and the price of different chips varies greatly. Chips in Japan and the United States are more expensive. Generally, the prices of chips made in Taiwan and China are lower than those in Japan and the United States.
8. Chip size The size of the chip is expressed by the side length. The quality of the large chip LED is better than that of the small chip. The price is proportional to the size of the chip.
