As a semiconductor light source, white LED is only about 20% of the power consumption of the traditional lighting source. The service life is as long as 100,000 hours, which is dozens of times that of ordinary lamps. It has good reliability and low cost of protection. The operating voltage is low, and the operating voltage is usually below 5V. In addition to the LCD backlight of portable machines, it can also be used for outdoor lighting, remote mountain lighting, miner's lights and water environment lighting. The switching time is short, and the response time can be as low as 1 microsecond, usually a few milliseconds for lamps (the response time of the current light source is 200 milliseconds). Environmental protection, no hazardous waste such as mercury, consolidate and not easily broken, and reduce the pollution of waste to the environment. LED light does not contain infrared and ultraviolet components, no radiation pollution, and DC drive, no stroboscopic, is an environmentally friendly light source to protect eyesight. With the wide use of LEDs and the improvement of their functions, it has become the consensus of everyone that a new lighting innovation is about to arrive. So what will this waiting innovation bring to you: This is the most important thing to develop LED application products and guide the development of the market. doubt.

1. The clutter of LED light-emitting fonts and the different standards of different projects require the light source to have versatility that is not constrained by the font;

2. Because it is extremely inconvenient to repair the completed LED luminous characters, in order to reduce the repair cost, the light source needs to have a longer lifespan;

3. LED light-emitting characters must meet the brightness of the LED light-emitting module manufactured by Nanjing Biya Engineering Department on the above requirements, and have the above functions. LED light source suitable for three-dimensional luminous characters supplied by Biya

There are two kinds: Piranha and Little Straw Hat. Piranha light-emitting module is suitable for light-emitting words with a height of 8-10cm on the word wall.

Generally speaking, piranhas with ￠3 and ￠5 heads have light-emitting viewpoints of about 90 degrees and 120 degrees. At this distance, the piranha light-emitting module used on the blister lettering can completely radiate the light. Not only the number of modules is saved, but also the utilization rate of light intensity is adequate after the screen luminance meter test. As for the blister luminous characters and carved luminous characters with short word walls and glyphs, it is necessary to choose the flat head piranha module and the small straw hat luminous module with a luminous viewpoint of about 160 degrees. The larger light radiation area can reduce the module usage, and the shorter font wall improves the luminous brightness of the font. The organic combination of the two follows the law of conservation of energy, and also shows the importance of correctly selecting LEDs.

It is worth noting that in the process of using LED light-emitting modules, we must pay attention to the problem of voltage drop. Don't just make one loop, from the beginning to the end. Doing so will not only make the brightness inconsistent between the head and tail due to different voltages, but also cause the problem that the single-circuit current is too large to burn the circuit board. The correct way is to connect as many circuits in parallel as possible to ensure a reasonable distribution of voltage and current. In addition, if the interior of the word cavity needs to use anti-corrosion materials, it is best to use a white primer to increase its reflectivity.

The application of LED in ultra-thin signs The ultra-thin luminous signs came into being on the basis of improving the utilization rate of business places. The thickness of the previous ultra-thin luminous signs and ultra-thin luminous light boxes is roughly between 1.5-3.0cm. In 2004, Nanjing Biya Company independently developed a set of ultra-thin signs with a thickness of 0.8-1.5cm on this basis. This product uses a variety of skills such as light guide, injection molding, carving, backlight and so on. It is characterized by a flat appearance, no carving bumps, and even light without strings. The layout can be enlarged indefinitely, as small as department cards and road signs to expressways can be manufactured. In the selection of LED, this kind of ultra-thin sign can be selected according to the thickness and layout size required by customers. For ultra-thin luminous signs with a thickness of less than 8mm and an area of ??450cm2 or less, SMD light-emitting modules can be selected; for ultra-thin luminous signs with a thickness of 8mm-10mm and an area of ??500cm2-400cm2, pixel tube light-emitting modules can be used. ; For large and ultra-thin light-emitting signs with a thickness of more than 10mm, a super-bright light-emitting module with a light-emitting angle of less than 30 degrees should be selected.

All in all, when using LED application technology to manufacture LED luminous characters, colleagues in the broad advertising industry should not only consider the stability of LED luminous characters, but also determine the luminous point of view, brightness and the relationship between the tube and the tube according to the needs of the product. Whether the wavelength can be within the allowable range. Only reasonable selection of LEDs of different standards can ensure the quality of the products, and at the same time, the cost of production is minimized. The scene-based LED overall lighting system and its characteristics, energy saving and environmental protection, are social issues that are widely valued by all countries in the world today, and directly affect the sustainable development of human society. For the lighting industry, which directly consumes power, it is increasingly expected to achieve energy-saving green lighting. The birth of semiconductor green lighting source is hailed as an innovation in the field of lighting. Its symbol is that semiconductor light-emitting diodes (LEDs) have gradually entered the general lighting market as a new type of light source from the special lighting market, and the market has a very broad prospect. As the application of special lighting sources, white LEDs have shown infinite functional advantages, strong development momentum and rapidly growing market demand. In the next 5 years, LED lights are likely to become the mainstream commodity of next-generation lighting.

The light-emitting diode light bulb is substantially different from the traditional white light in terms of structure and light-emitting principle. For a long time, the reason why people have not used light-emitting diodes for lighting is mainly because on the one hand, light-emitting diodes say that the light does not complete the three primary colors of red, green and blue, nor can it achieve white light; on the other hand, the luminous intensity and light efficiency cannot reach the lighting need. Now this puzzling problem has finally been solved. We use ultra-high-brightness blue LEDs as the basis, and use a variety of methods to achieve white light. The light emitted by the light-emitting diode bulbs that can emit white light is very close to sunlight, and has a good application prospect. Because of this, LED bulbs will stand out from the traditional indicator lights of electronic equipment and become a new star in the field of lighting, resulting in a new lighting innovation. Semiconductor ultra-bright light-emitting diodes (LEDs), especially nitride white light-emitting diodes, have the advantages of small size, low voltage, long life, fast response, no flicker, less energy consumption, less heat generation, etc., and are gradually becoming a new generation of Green, energy-saving, environmentally friendly, and long-lived lighting sources.
