Luminous character production is beautiful and generous, bright at night, energy saving, durable, so it is well received by customers. High quality LED luminous words not only take a long time, but also have good effect. Therefore, in the design and installation of LED, we need to do the following to ensure the quality of LED luminous words.
First of all, according to the process flow to make LED light-emitting words.
The production of high quality LED luminous characters must be carried out in strict accordance with the production process. Generally speaking, the generation of LED luminous characters can be divided into the following steps: large characters are punched with machine tools (the aperture is determined according to the size of LED / b]), the carved characters are welded with three-dimensional edges, and the edges and corners are polished. E letter has no burr, the font is painted, and the LED lamp is installed finally.
2、 Select the appropriate LED light source luminous characteristics.
The font of LED luminous characters is more complex, and the specifications of different items are different, which requires that the light source is not limited by the font. After the installation of LED luminous characters, maintenance is very inconvenient, so in order to reduce the maintenance cost, it needs a longer life of the light source. In addition, there must be sufficient brightness.
3、 Ensure that led luminous characteristics are pure and bright.
Some customers report that the colors they emit are pure and bright when they are just installed, but after a while, the colors darken, making the font glow in different colors, very ugly. The main reason is that LED light-emitting words generally use 20 mA current. Beyond this value, although the brightness will increase a little, the color attenuation will be significantly accelerated. Therefore, we can not covet the immediate effect, when purchasing the assembled LED luminous word module, we must test its output current value.
4、 The installation of LED luminous characters should be standardized.
In order to avoid the LED luminous characters appear bright at one end but not at the other end, the light in the front and back of a row of words, even the whole word brightness is uneven, and the color changes before and after are inconsistent. It should be noted that: the controller (or transformer) is installed in a line of words in the middle to avoid uneven light; each word must be directly connected to the controller (or transformer); or the transformer connection, that is, the parallel connection is used. If it is a large character, a word stroke must be c. The wiring should be conducted in such a way; the conductor should not be too small, and it is appropriate to use about 0.3 fancy wire; the controller (or transformer) should be as close to the light word as possible to reduce power consumption.
The luminous character maker has the advantages of high brightness, energy saving and easy maintenance. They are installed in high-rise buildings and advertising buildings. From a distance, they not only play the role of advertising, but also are beautiful and beautiful. Therefore, when we make and install LED luminous characters, we must start from many aspects to ensure its quality, so as to maximize its advantages and role.
