Today, we are going to discuss the question about how to test LED lamp beads.
Here are 9 ways:
1. Brightness
The prices of LED beads with different brightness will be different.
2. Anti-static Electricity Ability
The anti-static electricity ability of LED beads is generally greater than 700V. LED beads that with strong ability to against static electricity will be more expensive durable.
3. Wavelength Consistency
LED beads with the same wavelength will give off the same color of light. To produce pure color LED beads, manufacturers must use LED beads spectrometer.
4. Electric Leakage
We can check the products to see whether there will be electric leakage. If that phenomenon appears, it indicates that there is reverse current. The life of the LED beads with large leakage current will be short, and their price will be low.
5. Luminous Angle
Luminous angles of the LED beads that are used for different purposes are not the same. The prices of LED beads with special luminous angle are more expensive than those with ordinary one.
6. Service Life
We can evaluate the service life of LED beads. Long service life is a main feature of a LED beads with high quality. Service life is inversely proportional to lumen depreciation and directly proportional to price
7. Chips
I believe we all know that the higher the chip grade, the more expensive the price. And in fact, the prices of the chips are also related to the producing region. For example, chips made in Japan or the United States are more expensive.
8. Size of The Chip
The quality of the LED beads with large chips are better than those of small chips, and the price is proportional to the size of the chip.
9. Performance
For performance, we have many indicators to measure, including the quality of the colloid used by the LED lamp beads, the reliability of the design of all aspects of the LED beads and so on.
