Why is the price difference between LED lamp beads so big?

LED lamp beads are quite popular now. Whether it is making art light sources or making direct LED lighting fixtures, it plays an irreplaceable and increasingly important position. However, I believe that when you buy LED lamp beads in the market, it is very easy to find that the prices of LED lamp beads produced and sold by different LED lighting manufacturers aren't exactly the same, so here is the main introduction to this problem. Why is there such a big difference between the prices of SMD LED lamp bead light sources? The main reasons are as follows:

1. The cheaper SMD LED lamp beads have small chip size, relatively rough electrodes, poor current resistance and temperature and humidity changes, fast light loss, and short cycle. The price of LED lamp beads can be quite different. The gap is mainly reflected in the stability and light loss characteristics of SMD LED lamp beads.

2. The price difference of components such as resistors and capacitors driven by SMD LED lamp beads, IC, and other components is also very large. If there is a little error in the rationality of the circuit design, it will directly affect the product quality. Constant current and SMD LED lamp beads must need constant current to better guarantee the quality and service life.

3. SMD LED lamp beads are attached to the surface of the circuit board, are suitable for SMT processing, and can be reflowed. The flatness, viewing angle, chromaticity, stability, consistency, and other issues are well dealt with, and a lighter PCB board and reflective layer material are used, and the heavier carbon steel material pins of the in-line LED lamp beads are changed to make the display The reflective layer needs to be filled with less epoxy resin, which reduces the material size and reduces the weight.

LED products with different prices are likely to directly affect the characteristics and quality, so we must consider them carefully when purchasing.
