Lamp bead is the most important component of indoor LED display, and also the most used core device, which directly affects the use effect of LED display.Tens of thousands of LED beads will be used for every square meter of indoor LED display. Take P1.5625 indoor small spacing LED display for example, 409,600 LED beads will be 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 a quality indoor LED display.The use of inferior LED beads not only affects the display effect, but also greatly reduces the display life. It is even easy to have problems such as dead lights and big color difference.Therefore, the high-quality indoor LED display must be the display with high-quality LED beads, so it becomes a very important work to identify the quality of lamp beads.Next, deluncel (www.zhangchongshun.cn) tells you six methods to identify lamp beads, easily solve the problem.
Look at the brackets.Generally, the bracket is silver-plated copper bracket. The advantage of silver-plated copper bracket is fast heat dissipation, which can better heat dissipation of lamp beads with small resistance.Some merchants in the market will replace silver-plated copper bracket with ceramic bracket, which has excellent thermal conductivity.
Look at the brightness.How much LM(lumen) can your beads achieve, and LM(lumen) is the unit that measures the brightness of the beads.
3. See whether the luminescence is uniform and the color is consistent.Good quality lamp bead gives out light very even, color is consistent.Poor quality of lamp bead can appear a lamp bead brightness is bright, the phenomenon of lamp bead is dark, glow color is disordered and not unified, can have apparent dark area.
Four, see chip and chip size, chip is the quality of lamp bead decision factor.Generally, 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 index, brightness, anti - attenuation degree.
Look at the glue.Generally good lamp bead can use entrance glue, sealed LED lamp bead press with the hand not to be out of shape, cheap quality glue press can appear to be out of shape even crack wait for a phenomenon.
Sixth, see packaging technology.High quality LED beads have uniform color and good colloid consistency.This cannot be separated from good machine equipment, which is a key factor. Good equipment can guarantee the stability and consistency of products in various procedures and guarantee the yield of products.
Master the above six methods and easily solve the problem of identification of indoor LED display beads, so that you can buy high-quality and reliable LED display products.
