Teach you to give a reasonable price for LED letters

First, the complexity of LED luminous characters and the different specifications of different projects require that the light source should have the versatility of being unrestricted by the glyph;

Second, due to the installation of the completed LED luminous word maintenance is extremely inconvenient, in order to reduce maintenance costs, the light source is required to have a longer life;

Third, the LED luminous characters should have enough brightness to produce the LED lighting module, with the above functions. There are two types of LED light sources for three-dimensional luminous characters: piranhas and straw hats. The piranha light module is suitable for luminous characters with a word wall height of 8-10 cm.

In general, the piranhas at the heads of ¢3 and ¢5 emit light at angles of 90 degrees and 120 degrees. At this distance, the piranha light module is applied to the blister word, and the light can be completely radiated. Not only saves the number of modules, but also the utilization of light intensity is just right through the screen brightness meter test. For the short, word-shaped blister letters and engraved letters, the flat piranha module and the straw hat lighting module with a luminous angle of about 160 degrees are used. A larger area of ​​light radiation can reduce the amount of module used, while a shorter word wall increases the brightness of the font. The organic combination of the two follows the law of conservation of energy and also reflects the importance of choosing the right LED.

It is worth noting that in the process of using LED lighting modules, LED lighting words must pay attention to the voltage drop. Don't just make a loop, from the first to the end. This will not only cause the brightness to be inconsistent between the first and the last due to the difference in voltage, but also cause a problem that the single circuit current is too large to burn the circuit board. The correct approach is to connect as many circuits as possible to ensure proper voltage and current distribution. In addition, if you need to use anti-corrosion materials inside the word cavity, it is best to use a white primer to increase its reflection coefficient.

As a semiconductor light source, white light LEDs consume only about 20% of the power compared to conventional illumination sources. The service life is up to 100,000 hours, which is dozens of times that of ordinary lamps. It has good reliability and low maintenance costs. The use voltage is low, the working voltage is generally below 5V, in addition to the liquid crystal backlight of portable machines, it can also be used for field lighting, remote mountain lighting, miner lights and water environment lighting. The switching time is short, the response time can be as low as 1 microsecond, and the general luminaire is several milliseconds (the current light source response time is 200 milliseconds). With the widespread use of LEDs and the improvement of performance, a new lighting revolution is coming to a consensus, what will this change bring to people: this is the most concerned about developing LED application products and guiding market development. The problem.
