Every customer wants to buy a high-quality indoor LED display. The use of inferior LED lamp beads will not only affect the display effect, but also greatly reduce the life of the display screen, and even problems such as dead lights and large chromatic aberration are prone to occur. Therefore, a high-quality indoor LED display must be a display using high-quality LED lamp beads, so identifying the advantages and disadvantages of lamp beads has become a very important task. Next, the editor of Lianchengfa (www.lcf-led.cn) will tell you six identification methods to easily solve the problem of the advantages and disadvantages of lamp beads.

1. Look at the bracket. In general, the bracket is a silver-plated red copper bracket. The advantage of the silver-plated red copper bracket is that the heat dissipation is fast, which can better dissipate heat to the lamp beads and has a small resistance. Some merchants in the market will use ceramic brackets to replace silver-plated red copper brackets, and the thermal conductivity of ceramic brackets is very good.

Second, look at the brightness. How many LM (lumens) can your lamp bead reach, LM (lumen) is a unit to measure the brightness of the lamp bead.

3. Check whether the light is uniform and whether the color is consistent. Good quality lamp beads emit light evenly and have the same color. Poor quality lamp beads will have a bright lamp bead brightness and a dark lamp bead phenomenon, the color of the light is messy and inconsistent, and there will be obvious dark areas.

Fourth, look at the chip and the size of the chip, and the chip is the determinant of the quality of the lamp bead. In general, the larger the chip, the stronger the stability, the higher the brightness, and the better the heat dissipation. This is the most important, because the chip directly determines the color rendering index, brightness, and anti-fading degree.

Fifth, look at the glue. Generally, good lamp beads will use imported glue. The packaged LED lamp beads will not be deformed by hand, and the low-quality glue will deform or even crack when pressed.

Sixth, look at the packaging process. Good quality LED lamp beads have uniform color and good colloid consistency. This is inseparable from good machinery and equipment. The production of machinery and equipment is a key factor. Good equipment can ensure the stability and consistency of products in various procedures and ensure the yield of products.

Master the above six methods, easily solve the problem of identifying the advantages and disadvantages of indoor LED display lamp beads, so that you can buy high-quality and reliable LED display products.
