Guangmai Technology is professional in making the High power infrared LED 1W 3W 850nm Epileds Chip.
How to distinguish between good and bad infrared LED lamp beads?
1. To distinguish between good and bad infrared LED lamp beads, first understand the wavelength and application range of infrared lamp beads.
Infra LED (infrared light LED)
▲Using 660 nm -730 nm -780 nm light will promote plant growth.
▲ 730nm-760nm can be made into medical products to check whether the patient is a vegetable.
▲760 nm-790nm-805nm is used in medicine to detect fat content.
▲850 nm -880 nm is used to detect engine speed.
▲900 nm is mainly used as a testing instrument to detect human blood gas, blood sugar, etc.
▲940 nm is mainly used as a remote control for position locking.
▲1000 nm -1300 nm -1500 nm -1550 nm is made into a detection instrument that mainly detects human alcohol/fiber/carbon monoxide/carbon dioxide and other volatile gases.
2. How to distinguish between good and bad infrared LED lamp beads.
1. Look at the brightness: brightness The brightness of the LED is different, and the price is different. The LED used in the fixture should meet the laser class Ⅰ standard.
2. Test antistatic ability: LEDs with strong antistatic ability and strong antistatic ability have long life and high price. Generally, only LEDs with antistatic properties greater than 700V can be used for LEDs.
3. Test whether the consistency of wavelength is up to standard: LEDs with the same wavelength and wavelength have the same 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. Test for leakage: Leakage current LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage. LEDs with large leakage current have short life and low price.
5. Look at the light-emitting angle: 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. Evaluate the service life: The key to different qualities of life is life, and life is determined by light decay. Low light decay, long life, long life, high price.
7. Distinguish the grade of the chip: The luminous body of the chip LED is a chip, and the price of different chips is very different. 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. Distinguish the size of the chip: the size of the chip. The size of the chip is expressed by the length of the side. 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.
9. Check whether the safety performance is up to standard: The colloid of ordinary LED is usually epoxy resin, and the price of LED with anti-ultraviolet and fire retardant is more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fireproof. Each product will have a different design, different designs are suitable for different purposes, and the reliability of LED lighting.
10. The design aspects include: electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, safe use time and other factors. From the perspective of electrical safety, it should comply with relevant international and national standards.
GMKJ makes all the infrared led with 30 degree, 60 degree, 90 degree and also 120 degree lighting angle here.
All lighting angle can be customized here.
