How To Distinguish 5mm LEDs From Good Or Bad?

Nov. 27, 2018

5mm LED lamp pearl light decay: 5000 hours of light decay is only three thousandths, product consistency is good; 5mm LED lamp bead efficient light distribution: using a unique light distribution design, the chip can be more evenly distributed, reducing the distribution Glare.

1. Look at the brightness: The brightness of the brightness LED is different and the price is different. The LEDs used for the appliance shall comply with the laser class I standard.

2. Measuring antistatic ability: antistatic ability LED with strong antistatic ability, long life, and therefore high price. LEDs with an antistatic greater than 700V are typically used for LEDs.

3. Whether the consistency of the test wavelength is up to standard: LEDs with the same wavelength and wavelength have the same color. If the color is consistent, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.

4. Test whether leakage: Leakage current LED is a unidirectional conductive illuminator. If there is reverse current, it is called leakage, LED with large leakage current, short life and low price.

5. Look at the angle of illumination: LEDs with different illumination angles have different illumination angles. Special lighting angle, the price is higher. Such as the full diffusing angle, the price is higher.

6. Assess the life of the use: The key to different quality of life is the life, which is determined by the light decay. Low light decay, long life, long life and high price.

7. Differentiate the level of the chip: The illuminant of the wafer LED is a wafer, and the price of the different wafers is very different.

8. Differentiate the size of the chip: The size of the wafer The size of the wafer is expressed by the side length, and the quality of the large-wafer LED is better than that of the small wafer. The price is proportional to the size of the wafer.

9. See if the safety performance is up to standard: the colloid of the ordinary LED is generally epoxy resin, and the LED with anti-ultraviolet and fire retardant is more expensive. The high-quality outdoor LED lighting should be resistant to ultraviolet rays and fire.

10. The design of reliability includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, and safe use time. From the perspective of electrical safety, it should comply with relevant international and national standards.

We also have 8mm LEDs in various colors for you to provide, and we provide you with LED light emitting diode with quality assurance.
