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 the proportion of lamp beads in the overall cost of LED transparent screens is also the largest, 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?
1, see stents stent is silver-plated red copper stent, the benefits of silver-plated red copper stent is fast, you can better give the lamp heat resistance is small. Some merchants on the market will use ceramic brackets instead of silver-plated copper brackets. Ceramic brackets have excellent thermal conductivity.
2, to see the brightness of your lamp beads can reach how much LM (lumens), LM (lumens) is a measure of the brightness of the lamp unit.
3, see the light to see if the light is uniform color is the same, the quality of the good lamp light is very uniform, the same color. 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.
4, look at the chip to see the chip and chip size, the chip is a decisive factor in the quality of the lamp beads, under normal circumstances the greater the stability of the chip is stronger, 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.
5, to see the glue is generally a good product will use imported glue, packaged LED lamp beads by hand is not deformed, low-quality glue will appear deformation or even cracking and other phenomena.
6, see the packaging process quality LED lamp beads uniform color, 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. The above is a small method to identify the advantages and disadvantages of transparent full-color LED display screens. In addition, choose LED transparent screen manufacturers, be sure to choose a regular, industry-renowned, strong manufacturers, product quality assured, done a lot of cases, provide Comprehensive integration of products and solutions.
