How To Identify LED Display Lamp Beads?

First: Look at the brightness, which is how many LM (lumen) of your lamp beads that you usually say. LM (lumen) is a unit that measures the brightness of the beads.

Second: See whether the coloring is uniform color or whether the quality of the quality is uniform and the color is consistent. The lamp beads with poor quality will appear brightness of a lamp bead, a dark phenomenon of light beads, and the glowing color is messy and uniform, and there will be obvious dark areas.

Third: Look at the size of the chip and chip, and the chip is the decisive factor of good quality of lamp beads. Generally, the larger the chip is, the stronger the stability, the higher the brightness, and the better the heat dissipation.

Fourth: Look at glue and fluorescent powder. Generally, good products will use imported glue. The encapsulated lamp bead presses without deformation by hand. The quality of low quality will deformed or even cracking.

Fifth: Look at the bracket. Generally, 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 heat the lamp beads and the resistance is small. Some merchants in the market will use ceramic brackets to replace silver -plated red copper brackets. Ceramic brackets are very good.

Sixth: Look at the packaging process. The quality of the LED lamp beads is uniform and the collagen consistency is good. This is inseparable from good machinery and equipment. Production machinery and equipment are a critical factor. Good equipment can ensure the stability and consistency of the product on each program, and to ensure the product's good product.

In fact, the most important thing is to look at the chip of the lamp beads. The chip directly determines the color rendering index, brightness, and the degree of resistance.
