How to judge whether the quality of outdoor LED display is good or bad?
In modern society, business activities are more and more frequent, and various businesses are trying to increase publicity and improve company performance. Various marketing techniques are full of tricks, including the use of outdoor LED displays to rally. Outdoor LED displays are widely used in commercial activities today. Do you know how to judge their merits? The following small series for everyone to introduce it. LED lamp bead is the key device used in most of LED display screens , and it uses thousands to tens of thousands of lamp beads per square meter. Lamp bead is also the main body that decides the optical display performance of the entire display screen. It directly influences the evaluation of the display screen by the audience. Lamp bead has the largest proportion of the overall cost of the LED display screen, ranging from 30% to 70%. It goes without saying. LED lamp bead is the main decisive factor of the quality of outdoor LED display. Therefore, when we purchase outdoor LED display, we should focus on judging the merits of LED lamp beads to judge whether an outdoor LED display is good or bad. You can judge from the following aspects. First, look at the brightness, which is what you usually say, how many LM (lumens) your lamp can reach, and LM (lumen) is the unit that measures the brightness of the lamp. Second, to see whether the uniform color of the light 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. Third, look at 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. Fourth, look at the glue and phosphor, generally good products will use imported glue, the sealed lamp beads will not be deformed by hand, and the low-quality glue will be deformed or even cracked. V. Look at the brackets. In general, the brackets are silver-plated copper brackets. The advantage of the silver-plated copper brackets is that they can dissipate heat quickly, and they can provide better heat dissipation to the lamp beads. Some merchants on the market will use ceramic brackets instead of silver-plated copper brackets. Ceramic brackets have excellent thermal conductivity. Six, look at the packaging process, good 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 summary of Lianchengfa Xiaobian's judging the merits of outdoor LED display, and hopes to help everyone.
