Why is there such a big difference between the prices of SMD LED lamp beads? Here is how Hollight will discuss and discuss with everyone:

1. SMD LED lamp beads Low-priced SMD LED lamp beads have smaller chip sizes, rough electrodes, poor resistance to current and temperature and humidity changes, fast light decay, and short life. They are just the same color and the same brightness. The price of LED lamp beads can vary several times. The distance is mainly reflected in the reliability and light attenuation of the SMD LED lamp beads.

2. The price of SMD LED lamp bead drive resistors, capacitors, ICs and other components are also very different. If the circuit design is not correct, it will directly affect the quality of the product, and some may just be constant voltage, but not achieved. Constant current, and SMD LED lamp beads must require constant current to better ensure quality and service life.

3. SMD LED lamp beads are attached to the surface of the circuit board, suitable for SMT processing, and can be reflow soldered. The flatness, viewing angle, brightness, reliability, consistency and other issues are well handled, lighter PCB board and reflective layer materials are selected, and the heavier carbon steel material pins of the in-line LED lamp beads are changed to make flashing reflections The layer needs to be filled with less epoxy resin, which reduces the product size and weight.

Products with different prices may directly affect the performance and quality of the product, so you must carefully consider when purchasing.
