On the roof of some large buildings, we can see a lot of dot-shaped the luminous letters on the roof sign product, why do you seem to have a single point of illumination, because those points are LED light sources, this source is embedded in the building In the hole position of the luminous letters on the roof shell, in the jargon of our sign industry, this kind of luminous word is called punching luminous letters, and it can also be called perforated luminous letters.Some people may ask, must the luminous letters on the roof be punched? In fact, there is no such regulation. The specific demand depends on the choice of the customer. It is the production of traditional flat-type luminous letters or punch-type luminous letters, which will affect the structure of the building itself, as well as the safety of the products. There are production costs, different types of the luminous letters on the roof, there will be great differences,Today, we select a typical punching type luminous letters on the roof on the market as a sample to analyze the advantages of the market-accepted punching type luminous letters on the roof. Compared with ordinary flat roof letters, the punched roof has the following five advantages:

Advantages 1: Not limited by the size of the luminous letters strokes,We know that the letters shell is made up of countless strokes,and a lot of Chinese strokes are more,If it is a calligraphy body with some artistic elements, some strokes may be small and narrow. If traditional acrylic letters are used, the built-in LED module may not be assembled, resulting in insufficient brightness or unevenness of some strokes of the luminous letters. The punching type luminous letters on the roof just solves this problem. No matter how large the size of the shell, it is perforated on the surface of the shell, and then the lamp bead is installed in each hole.

Advantages 2: The brightness is high, because the position of the luminous letters on the roof is relatively high, and it is far away from the crowd, so it must be guaranteed. The traditional acrylic luminous letters is blocked by the acrylic panel because the light source is installed in the letters shell, so the brightness will be affected to some extent. The punching type luminous letters on the roof has different luminous letters, and the light beam of the lamp is spread without any obstruction. The brightness is adequately guaranteed;

Advantages 3:Uniform distribution of light beam，We can see a lot of light boxes or acrylic letters on the streets and lanes have different brightness. This phenomenon is usually caused by the problem of light source. The uneven arrangement of the light sources is a common problem. Based on various factors, the internal LED modules of the acrylic letters it is impossible for the group to fill the entire plane. Since there is no gap, there must be a gap, and this gap is installed by the experience in the irregular light-emitting pen-shaped shell, and there is no way to achieve absolute uniformity. However, the punching type luminous letters can solve the problem of unevenness of the light source by punching, and the direct effect is the uniform divergence of the light beam after power-on;

Advantages 4:Low production cost,The shell of the punching type luminous letters on the roof has only one set to be made. Unlike the acrylic letters, the metal shell and the edging are first made, then the acrylic shell is made, and finally the two are stitched together to make the process complexity. It can be imagined that whether it is the raw material or the complexity of the process, the cost will be involved. In comparison, the cost of the punching type luminous letters on the roof is significantly lower;

Advantages 5：Low maintenance costs,Since the lamp beads of the punching type luminous letters are installed one by one in the hole position, if a light ball is not bright, it can be pulled out from the outside, and the new one is solved, and the maintenance cost is very low. However, the traditional acrylic letters are troublesome, and the light source is installed inside the shell. If the light source has a problem, the acrylic panel must be partially removed to see the light source, and the maintenance cost is obviously higher;

As a branch of the advertising sign, the market for punching type luminous letters on the roof has flourished in recent years. Among them, punching type luminous letters are a relatively large category in the luminous letters on the roof, and the products that can win in the market segment. There must be its unique value. In addition to the above five advantages mentioned above, the luminous letters on the roof has more advantages than other types of luminous letters, as long as we change the reference object, compare the the angle is changed, the advantage is that it can't be found. In short, the products that can meet the customer's needs from all aspects are good products.
