LED Lamp bead is the most important component of the Transparent LED Display, and also the key device that uses the most, directly affecting the use effect of the LED transparent screen. Thousands to tens of thousands of lamp beads are used per square meter of transparent screen, and lamp beads are the largest proportion of the total cost of LED transparent screens, ranging from 40% to 70%.
For customers, they all hope to purchase high-quality LED transparent screens and use inferior LED lamp beads, which will not only affect the display effect of transparent screens, but also greatly reduce the life expectancy, and even cause problems such as dead lights and large color differences. Therefore, the identification of lamp beads has become a very important part. So how to identify the advantages and disadvantages of transparent LED display lights?
First: stents. In general, the bracket is a silver-plated copper bracket. The advantage of the silver-plated copper bracket is that it can dissipate heat quickly, and it can provide better heat dissipation to the lamp. Some merchants on the market will use ceramic brackets instead of silver-plated copper brackets, ceramic brackets have excellent thermal conductivity.
Second: brightness. How many LM (Lumens) your lamp beads can reach, and LM (Lumens) is a measure of the brightness of the lamp beads.
Third: Whether the light emission is uniform or not. The quality of the good lamp light is uniform and the color is uniform. Poor quality lamp beads will have a bright light bulb, a lamp light dark phenomenon, the light color is not uniform, there will be obvious dark areas.
Fourth: chip and chip size. The chip is also a decisive factor in the quality of the lamp beads. In general, the larger the chip, the stronger the stability. The higher the brightness, the better the heat dissipation. This is the most important, because the chip directly determines the color rendering index, brightness, and the degree of attenuation.
Fifth: glue. Generally good products will use imported glue. The encapsulated LED lamp beads will not be deformed by hand. The low-quality glue will be deformed or even cracked.
Sixth: Encapsulation process. The LED bulbs with good quality have uniform color and good colloidal consistency. This is inseparable from good machinery and equipment. The production of machinery and equipment is a key factor. A good equipment can guarantee the stability and consistency of products in various procedures and guarantee the product's yield rate.
