How to distinguish the quality of indoor LED display lamp beads?

by:Toponetech     2021-05-13
Lamp beads are the most important component of indoor LED display screens, and the most used core device, which directly affects the use of indoor LED display screens. Every square meter indoor LED display uses thousands of LED lamp beads. Taking the indoor small-pitch LED display P1.5625 as an example, there are 409,600 lamp beads used per square meter. Lamp beads account for the largest proportion of the overall cost of indoor LED displays, ranging from 40% to 70%. Every customer wants to buy high-quality indoor LED displays. 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 it is even prone to problems such as dead lights and large color differences. Therefore, a high-quality indoor LED display must be a display using high-quality LED lamp beads, so identifying the pros and cons of the lamp beads has become a very important task. Next, Topsun Optoelectronics tells you the six methods of identification to easily fix the pros and cons of the lamp beads. 1. Look at the bracket. In general, the bracket is a silver-plated copper bracket. The advantage of the silver-plated copper bracket is that it dissipates heat quickly, can better dissipate heat to the lamp beads, and has low resistance. Some merchants on the market will use ceramic brackets instead of silver-plated copper brackets. Ceramic brackets have excellent thermal conductivity. Second, look at the brightness. How many LM (lumens) your lamp beads can reach, LM (lumens) is a unit to measure the brightness of the lamp beads. 3. See if the light is uniform and the color is consistent. The high-quality lamp beads emit light evenly and have the same color. Poor-quality lamp beads will have the phenomenon that one lamp bead is bright and one is dark, and the luminous color is messy and uneven, and there will be obvious dark areas. Fourth, look at the chip and the size of the chip, the chip is the decisive factor for the quality of the lamp beads. 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-attenuation degree. Five, 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 colloidal consistency. This is inseparable from good machinery and equipment. Production machinery and equipment is a very critical factor. Good equipment can ensure the stability and consistency of the product in various procedures and ensure the yield of the product. Master the above six methods to easily solve the problem of identifying the advantages and disadvantages of indoor LED display beads, allowing you to purchase high-quality and assured touch display products.
