We all know that there are many manufacturers of luminous characters in the market, but this also reflects a problem. The quality is definitely uneven. So how do we distinguish the quality of luminous characters? I will teach you all today.

Look at the brightness, uniformity, the brightness of the stainless steel luminous characters is good, the luminescence is uniform, there is no light spot, no dark area, especially the stainless steel luminous characters cannot be clearly seen from the front or the side. , Affect the image.

According to the performance, it can be waterproof (basic requirements), can resist freezing, and can be heat-resistant, so as to adapt to the climate of various seasons, such as the use of polymer material LED light source can generally be achieved, unless the technology is not mastered at all. The life of the light source depends on the correct circuit design, including the voltage and current in the normal range of use. Increasing the current to increase the brightness is not advisable, which is equivalent to drinking poison to quench thirst and exhaustion to fish. For the technology introduction party, the most important thing is to look at the production speed and efficiency, the rationality of the formula and the craftsmanship. The practice of large and small characters is different, so you have to look at the other party's characters as small as 10cm, as large as a few square meters. , The ability to make small prints does not mean that you can make big prints. The real thing with big prints doesn’t necessarily mean that you can do fine prints, so you have to look at the size and thickness. There are different solutions and production methods for different fonts, sizes, and colors. For example, our light source has three solutions, and the cost is very different, which can meet different customer needs. For example, we can use molds without molds, or the two are reasonable. Application, reasonable production and installation for specific occasions. Of course, these issues cannot be decided immediately based on appearance alone.

Look at the appearance, the appearance is bright in color, the font is smooth, it stretches freely, the smoothness is high, the surface and sides are flawless, and there is no gap, just like a girl, so people like it.

The light source LED of the dot matrix luminous characters is used as a semiconductor light source, and its power consumption is only about 20% of that of the traditional lighting source. The service life is as long as 10,000 hours, which is dozens of times that of ordinary lamps. It has good reliability and low maintenance cost. The operating voltage is low, and the working voltage is generally 12V. In addition to the LCD backlight of portable machines, it can also be used for outdoor lighting, remote mountain lighting, miner's lamp and water environment lighting.

The switching time is short, and the response time can be as low as 1 microsecond, and the general lamp is several milliseconds. Environmental protection, no harmful waste such as mercury, strong and not easily broken, reducing waste pollution to the environment. The stainless steel luminous light source LED light does not contain infrared and ultraviolet components, has no radiation pollution, and is driven by DC and has no flicker. It is an environmentally friendly light source that protects eyesight.
