LED Light Source Light Source Selection

LED can save a lot of electricity for the country and users, and save a lot of work hours for inheritance. The development of LED application technology has added new vitality to the competitive advertising industry. Its unique, different glowing situation, and widely used in the production field of advertising products. Different specifications of LED lamp beads have different luminous angles and different brightness. So, how to choose the appropriate LED lamp bead for different products, so that it can achieve the maximum effect and reduce costs to the greatest extent? Professional suggestions of the limited company now. The application and use of LEDs in the light -emitting characters The three -dimensional luminous characters have the following requirements for the light source: First, the complexity of the glyphs and the different specifications of different projects, the light source requires the universality of the light source; second, due to the due to the universality of the glyphs; The completion of the installation of light -emitting characters is extremely inconvenient. In order to reduce maintenance costs, the light source requires a long life;. There are three LED light sources suitable for three -dimensional light -emitting characters: people and small straw hats and patch lamp beads. Earnian light module is suitable for the glowing characters between the height of the word wall between 8-10cm?. Generally speaking, 3 and 头 头 讲 讲 一般 一般 is about 90 degrees and 120 degrees. In this distance, the luminous module applied on the sucking word, the light can be radiated at all. Not only does the number of modules save the number of modules, the use of screen brightness meter testing, the utilization rate of light strength is just right. For the short and glyph -shaped luminous characters and sculpture glowing characters, the glowing angle must be used at about 160 degrees of flat -headed mermaid module and small straw hat light module. The larger light radiation area can reduce the amount of module, and the shorter wall wall improves the glowing brightness of the font. The two organically combined, followed the law of energy conservation, and also reflected the importance of the correct choice of LED. It is worth noting that in the process of using the LED light module, we must pay attention to the problem of voltage drop. Never do only one loop, from the first series to the end. This will not only make the brightness inconsistent due to the different voltage between the first and tails, but also the problem of excessive single -circuit current burning the circuit board. The correct approach is to connect as much as possible to ensure that the voltage and current distribution is reasonable. In addition, if you need to use anticorrosive materials inside the word cavity, it is best to use white primer to increase its reflection coefficient. The application of LED in ultra -thin signs is an ultra -thin glowing sign. The thickness of the previous ultra-thin light emitting signs and ultra-thin light light boxes was roughly between 1.5-3.0cm. In 2004, on this basis, Nanjing Bia Company independently developed a set of ultra-thin signs with a thickness of 0.8-1.5cm. This product adopts a variety of technologies such as light guide, injection molding, carving, backlight sources. The characteristic is that the surface is flat, no sculpture bump marks, light and uniform light without string light. The layout can be infinitely larger, as small as the department card, and the road signs in the highway can be made. This ultra -thin sign is selected according to the thickness of the customer's requirements and the size of the layout according to the customer requirements. Ultra-thin light emitting signs with a thickness of less than 8mm and a area of less than 450cm2 can be selected for the micro-glowing module; the thickness is between 8mm-10mm and an ultra-thin light emitting sign between 500cm2-400cm2. ; Large ultra -thin light emitting signs with a thickness of more than 10mm, the ultra -high bright light module of the light angle within 30 degrees should be selected. In short, when the majority of advertising industry uses LED application technology to make products, in addition to considering the stability of LED, it is also necessary to determine the luminous angle of the LED according to the requirements of the product. Within. Only by reasonable selection of different specifications of LEDs can we ensure the quality of the product. Scenic LED overall lighting system and its characteristic energy conservation and protection environment are social issues that are generally concerned about countries around the world today, and directly affect the sustainable development of human society. For the lighting industry that consumes energy directly, it is more hoped to achieve energy -saving green lighting. The birth of the semiconductor green lighting light source is known as a revolution in the field of lighting. The symbol is that the semiconductor emitting diode (LED) is gradually entered the ordinary lighting market as a new light source. As the application of special lighting light sources, the white light LED has shown huge performance advantages, strong development momentum, and rapidly growing market demand. In the next 5 years, LED lights are likely to become the mainstream product of the next generation of lighting. The glowing diode light bulb is different from the traditional white -mounted lamp in terms of structure or luminous principle. For a long time, the reason why people have not used the light -emitting diode for lighting is mainly because on the one hand, the light emitting diode has not achieved red, green, and blue. Require. Now this problem that plagues people is finally solved. People are based on ultra -high brightness Blu -ray LED, and they use multiple ways to achieve white light. The light emitted by the light -emitting diode light bulb that can be developed is very close to the sun, and it has good application prospects. Because of this, the light -emitting diode light bulb will stand out from the traditional electronic equipment indicator light, becoming a new star in the field of lighting, leading to a new lighting revolution. Semiconductor ultra -high brightness light emitting diode (LED), especially nitride white light glowing diode, has the advantages of small volume, low voltage, long life, fast response, non -frequent flashing, less energy consumption, less fever, etc., and is gradually becoming a new generation of green. , Energy -saving, environmentally friendly, long -lived lighting source. As a semiconductor light source, white light LED, compared to the traditional lighting source, its power consumption is only equivalent to about 20%of the latter. The service life is up to 100,000 hours, which is dozens of times the ordinary lamps. It is reliable, low maintenance cost. The use voltage is low, and the working voltage is generally below 5V. In addition to the LCD backlight of portable machines, it can also be used in the field of field lighting, remote mountain area lighting, miner lights and water environment lighting, etc. The switching time is short, the lowest response time can reach 1 microsecond, and the general lamps are a few milliseconds (the current light source response time is 200 milliseconds). Environmental protection, no harmful waste such as mercury, sturdy and not fragile, reducing the pollution of the waste to the environment. LED lights do not contain infrared and ultraviolet ingredients, no radiation pollution, and DC drive, no flashing, is an environmentally friendly light source for protecting vision. With the extensive use of LED and the improvement of performance, a new lighting revolution is coming to become people's consensus, so what will this expectation change will bring people: this is the development of LED application products and guiding market development the most concerned The problem. The author believes that the following points are worthy of attention: (1) Except for brightness and color temperature, LED brings the development of the lighting of the color controlled and adjustable human society, which can be roughly divided into three stages. The first stage is from before the 18th century to the view of the original human beings. From ordinary firewood to oil lamps to candles, until a large amount of gas lamps and gasoline lamps used in the future. In this long history, people are pursuing light, which is a concept of brightness. The second stage is since the eighteenth century. People have begun to use electricity lighting. Since Edison in 1879, Edison has invented the white lanterns. It has been in use for nearly 130 years. The main lighting technology is thermal radiation and gas discharge technology. In order to save energy and applicable lighting, people have developed white lamps, fluorescent lamps, halogen lamps, high -pressure sodium lamps, mercury lamps, etc. These have become the mainstream products in our daily lighting. In addition to satisfying the concept of brightness at this stage, color temperature is also realized. Now that LED is used for lighting, it will start another new stage of lighting. The implementation of the three base -colored LEDs can be obtained by any visible light color, and it can be changed at any time. The regulation of brightness and color temperature is more convenient. (2) The transformation from a single lighting to emphasizing the overall effect. In our daily life, lighting is usually achieved by single or local lamps. LED is small in size and can be installed in architectural materials, decorative materials and crafts. Future lighting will no longer be limited to a single lamp, but will pursue the overall lighting effect. The light source may come from the ground, wall, window sill, furniture, accessories, handicrafts, lines, faces, or body light sources. According to the overall lighting Effects need to be set (such as color, temperature, brightness, direction, etc.). The light -emitting diode bulb is made of semiconductor. Therefore, this light -emitting device can be made very small to reach the sub -millimeter order and install it on the wall or ceiling. If you dont turn on the lights, you can hardly notice their existence. In addition, the long life of this bulb. In addition to the durability of long -term durability, this kind of light bulb also has great potential in terms of energy conservation. (3) The development of the lamp switch into the scene selection is usually completed by the switch to control a certain lamp to complete. In the future design that emphasizes the overall lighting effect, the overall arrangement of the light source makes the scene system possible. People can design different lighting effects according to different scenarios requirements. During the use process, people only need to choose the scene through the remote control to get the coordinated lighting effect. (4) Fixed installation from any discharge to replace the change from candles to electric lamps, so that only vertical installation can be developed into any direction and space for installation. Position limited. The LED light is driven by a low -voltage power supply. The safety line can be standardized. The buckle line can be arranged in any location and any shape, so that the LED light can be discharged at any time, creating different effects to create different effects. For single lights, you can hang it to different locations according to different needs of people. (5) Static landscape can be transformed into sound, light, and electric dynamic display LED response speed, small volume and color adjustment, so that color dynamics can be displayed as much as possible. It can be realized through software control on some occasions, which will bring life and dynamic to the lighting system. (6) Green sources such as solar energy and wind energy will become a lighting energy for light -driven energy for lighting energy. As a new high -efficiency solid light source, the LED power is relatively small, the light effect is high, the voltage is low, and the use of DC power is suitable for solar drive. LED is used for lighting, and provides a low load light source for solar energy use, making solar energy more widely used as possible, which will greatly promote the development of the solar industry. In the future, the LED lighting system is completely likely to use solar energy power supply. The developed products can also be used in areas where conventional grids cannot extend or are limited by geographical conditions. (7) Expansion of the concept of lighting, fully reflect the art, history, humanities, and personality LED lighting will change people's lighting concepts. In terms of color, lighting from the white light in the universal sense is expanded to a variety of colors of light. In fact, people do not need to be very bright in many cases. Maybe yellow light or other colors are more suitable for the needs and personality hobbies of the scene. Three -based LED can achieve continuous transformation and selection of brightness, grayscale, and color. Light has an important impact on people's mentality, so that people can choose different overall lighting effects at different times according to their personality requirements, scene conditions, and different understanding of the environment and life. Artistic lamps, dreamy colors, will integrate people and the environment, and give new connotations to lighting. With the increasing popularity of the green life concept, people began to yearn for a relaxed and happy life and work in the green environment and green buildings. With the implementation of lighting colors, people desire more tender and more personalized scenes. LED's broader application will definitely reflect the characteristics of the LED before they will have vitality. The overall lighting system that reflects the many characteristics of LEDs will be one of the important development directions of LED applications. The most important feature is to use LED to realize the emptiness, preset and selection of the scene of the scene. The content of the above seven points will become its basic feature. In order to achieve the overall LED lighting system of the scene, the hidden, artistic, and integrated LED lamps will receive attention. The combination of LED lamps and architecture and decorative materials, and artistic LED lamps, will be two important development directions for LED applications.
