Passing through the streets and alleys, we can see a wide variety of roof glowing words, inadvertently, you will find that there are always a few glowing words flashing, most of the time, the flashing roof glow words give people a very bad feeling. Sometimes the human eye can not accept such a high frequency of irregular flicker, to put it simply is dazzling; there are also some cases where the flicker is caused by unreasonable design to give people visual pollution. As a sign industry practitioner, standing in the perspective of the roof luminous word manufacturer, the flickering of the roof luminous word is likely to be a product failure, except for the flickering according to specific laws, according to the actual engineering cases of Cosay in the past few decades, there are usually 4 possible reasons for the flickering of the luminous word on the roof.
Reason 1, artificial design of the flicker, this situation is relatively small, large roof luminous words generally carry the output of corporate brand image, with the current network hot word to describe is to pursue the high-end atmosphere on the grade, or low-key luxury has connotations, very few large-scale roof luminous word projects will engage in that kind of flickering non-mainstream style, ordinary store signs using flashing non-mainstream style is a lot;
Reason 2, poor contact, the probability of this situation occurring is relatively large, and the location and environment of the roof luminous word installation has a close relationship, most of the luminous words are directly exposed to the high altitude without cover, long-term exposure to complex and changeable climatic factors, wind and rain and sun are commonplace, so the structure and circuit failure of the roof luminous word can not be avoided, the next is that the wire circuit is instantly cut off or the contact is good and bad, and finally reflected in the display effect of the roof glow word, the luminescence is unstable, That is, the situation that we finally see is flickering;
Reason 3, the wire load is not enough, in general, the power demand is relatively large electrical equipment needs to be equipped with relatively thick wires, and vice versa. The roof glow word is generally relatively large in size, the number of light sources is large, and the power is usually not too low, so the arrangement of the internal wires is more important, unlike the ground which small LED luminous words, directly with led light strips. The use of high-altitude roof large-scale luminous words on the wire this raw material can not be shrunk, some merchants in order to save costs, in the choice of wire suppliers also shrinkage, directly led to the final roof luminous word products luminous effect greatly reduced;
Reason 4, transformer failure, for large roof luminous words, the number of light sources directly determines how much transformer needs to be matched, if there is no problem in the line link, the situation of luminous word flickering will appear in the transformer link, according to the experience of Cosay, the manufacturer must have a set of standards to follow when making the roof luminous word, how many light sources correspond to how much power transformer, the two are one-to-one correspondence relationship, determined by the specific data where the interval is located;
The solutions corresponding to the above four common causes are as follows:
Reason 1 corresponding solution: The artificially designed flickering effect is pre-designed, so there is no need for special treatment;
Reason 2 corresponding solution: The occurrence of poor contact generally requires the manufacturer to assign professional engineers and electricians to the scene, check the details one by one, find the corresponding problematic line, and replace it to solve it;
Reason 3 corresponding solution: similar to the method of poor contact above, the load test of the circuit is carried out, and the part of the line that is not enough to support the electricity demand of the roof luminous word is directly replaced;
Cause 4 corresponding solution: Once other factors are excluded, determine that the cause of the flashing word is the transformer, directly replace the new one;
Judging from the experience of The Luminous Character Project on the roof of The Cosay in the past 20 years, most manufacturers have experienced similar problems with the flickering of the Luminous Character in the early stage of development. Facing the problem is not terrible, After a long period of continuous summary and technological innovation, through a series of technical research, from the source to control product quality, has solved similar multiple faults from the root. Do not let go of every line, the selection and installation of every light source is regarded as a battle, on the road to conquest, can only go forward bravely, there is no choice.
