There are many processes in the production process of LED light-emitting words, any process error may lead to unsatisfactory results, so how to produce high-quality LED light-emitting words?
1、 Making LED luminous characters according to the process
The production of high-quality LED characters, in strict accordance with the production process to produce. Generally speaking, the production of LED light-emitting characters can be divided into these steps: first, the whole sheet of large characters is punched with a machine tool (the aperture is determined according to the size of the LED), the carved characters are welded with three-dimensional edges, the edges and corners of the characters are polished without burr, the fonts are painted, and then the LED lights are installed.
2、 Choose the right light source for LED
The glyph of LED characters is complex, and the specifications of different projects are different, which requires that the light source can not be limited by the glyph. After the installation of LED light-emitting words, the maintenance is very inconvenient, so in order to reduce the maintenance cost, the light source is required to have a long life. In addition, there should be enough brightness.
3、 To ensure the pure color of LED luminous words
Some customers reflect that the color is pure and bright when it is just installed, but after a period of time, the color becomes dim, which makes the font glow, the color is different, and it becomes very ugly. The main reason is that the current used for LED luminous words is generally 20 mA, beyond this value, although the brightness will increase a little, but the color attenuation will be significantly accelerated. Therefore, we should not be greedy for the immediate effect, and we must test its output current value when purchasing the assembled LED luminous word module.
4、 Installation of LED light-emitting words needs standard operation
In order to avoid the situation that one end of LED light-emitting words is on and the other end is not on, the front of a typesetting is on and the back is slightly dark, and even the brightness of the whole word is uneven, and the color changes are inconsistent before and after, attention should be paid when installing: the controller (or transformer) should be installed in the middle of a typesetting to avoid uneven light-emitting; Each word must be directly connected to the controller (or transformer), that is, parallel connection is adopted. If it is a big word, the stroke of a word must be connected in this way; the wire should not be too small, and the fancy wire of about 0.3 should be used; the controller (or transformer) should be close to the luminous word as far as possible to reduce power consumption.
LED characters have many advantages, such as strong brightness, energy saving, easy maintenance and so on. They are installed in high buildings and buildings to advertise. From a distance, they not only play the role of advertising, but also are beautiful. Therefore, when we make and install LED light-emitting words, we must start from many aspects to ensure its quality, so as to give full play to its advantages and functions.
