Summary:
Since its birth, LED has been rapidly developed by the law of 30 times brightness increase and 10 times price drop every 10 years. It is breaking through the three major bottlenecks of high power, high light efficiency and low cost, and is constantly entering the commercial fast lane. In terms of monochromatic light, the light effects of red light, yellow light, blue light, and green light are constantly being updated.
As a new type of light source, high-power LED is a pioneer in opening up LED instead of traditional lighting. It not only breaks through the original application field and attracts more intense attention, but also brings unlimited business opportunities and reverie to the industry.
introduction:
Characteristics of high-power LED and comparison with other light sources
High-power LED as a light source for lighting has the following advantages:
1) Low power consumption: LEDs with a light efficiency of 75lm / w reduce power consumption by 80% compared to incandescent lamps of the same brightness;
2) Long life: the product life is up to 50,000 hours, 24 hours continuous lighting can be used for 7 years
3) Nanosecond response speed makes the dynamic control of brightness and color easy: it can realize dynamic color change and digital control
4) Large design space: It can realize the organic integration with the building and achieve the effect of seeing only the light but not the light.
5) Environmental protection: no harmful metal mercury, no infrared and ultraviolet radiation.
6) Color: different wavelengths produce different colored lights, bright and saturated, no need for filters, can be controlled by the three primary colors of red, green and blue to form a variety of different colors, can achieve a full color gradient and other color changing effects.
The lifespan of incandescent lamps, 5mm LEDs and Luxeon 1W high-power LEDs, high-power LEDs have a great advantage in life, while incandescent lamps and other traditional light sources have little room for improvement in many technologies.
1. Application of high-power LED in underwater lights
As the pace of urban construction accelerates, leisure squares and green parks have become the highlights of the city, representing the urbanites' desire to return to nature. Water represents spirituality. Waterscapes and fountains are an integral part of leisure squares and green parks. The demand for underwater lights is huge. At present, the color underwater lights are generally traditional PAR lights, and the need to add filters to produce various colors greatly reduces the luminous efficiency. Pinneng Optoelectronics has obtained through research that the total luminous flux of traditional lamps in red, green, and blue underwater lamps is 1 to 2 times that of LED underwater lamps. The packaging technology of LED determines that the direction of its light source is very strong, and LED The light source is very small and can be matched with optical lenses of various angles. These characteristics determine that the power consumption of traditional underwater lights is more than 13 times that of LED underwater lights. It can be seen that the energy saving effect of LED underwater lights is quite significant. In addition, the spectral distribution of LED determines its color purity and saturation is unmatched by traditional PAR lamps, so it has a strong competitive advantage.
LED packaging technology determines its light source is very luminous, as shown below:
Second, the application of high-power LED in acrylic luminous logo products
During the market research, Pinneng Optoelectronics found that the acrylic luminous logo as a substitute for neon lights has begun to rise in large cities such as Shanghai, Beijing and Guangzhou in the past two years under the exemplary role of many internationally renowned companies such as McDonald's and KFC. , They not only overcome the shortcomings of traditional neon lights, such as large power consumption, inconvenient maintenance, hidden safety hazards and lack of strokes, but also the characteristics of full color and uniform light transmission. At the same time, the design of the three-dimensional effect makes the logo not only bright at night Clear, dazzling, restrained temperament, elegant and dignified during the day, magnificent momentum, these two advantages are incomparable by neon signs or metal characters.

3. Application of LED in modern curtain wall buildings
The application of architectural glass in modern buildings is increasing, the variety is more and more, and the functions are more and more complete. The application amount, application type and function of architectural glass in the building can be used as a sign to evaluate the modernization degree of the building. Especially the decorative performance of architectural glass can be said to be ever-changing. Without architectural glass, there would be no modern building. However, due to the glass's ability to transmit light, as well as to reflect light and absorb light, the landscape lighting design supporting the building has become a model. How can the beauty of the texture of glass during the day be reproduced through the light? This is a general concern of landscape lighting designers. Pinneng Optoelectronics believes that for the lighting treatment of modern buildings with large-area glass, "architectural lighting" is used to integrate light-emitting devices (light sources) and building components, which not only deepens and expands the connotation of lighting fixtures, but also has many forms. The variety is refreshing.
The high-power LED has high single light efficiency, small unit volume, and great design flexibility. It can best match the structural characteristics of the light carrier and is easy to install. Provide a new lighting solution for such buildings.

Conclusion:
The semiconductor lighting industry is a vibrant future industry. The continuous improvement of packaging technology, heat dissipation technology, optical technology, application technology and control technology is promoting the accelerated development of this industry. A future of LED lighting with the successful application of high-power LEDs Has come.
A mining light tower is a tall structure equipped with powerful floodlights that are used to illuminate large areas in mining operations. These towers are typically portable and can be easily moved around the mining site as needed.
The main purpose of a mining light tower is to provide sufficient lighting for workers to safely carry out their tasks during nighttime or in areas with low visibility. This is particularly important in underground mines where natural light is limited or absent.
Mining light towers are usually powered by diesel generators or other portable power sources. They are designed to withstand harsh mining environments, including extreme temperatures, dust, and vibrations.
The height of the light tower allows for a wide coverage area, ensuring that the entire mining site is well-lit. The floodlights used in these towers are high-intensity discharge (HID) lamps or light-emitting diodes (LEDs) that can produce a bright and focused light beam.
In addition to providing illumination, some mining light towers may also have features such as telescopic masts, adjustable light angles, and remote control operation for enhanced convenience and flexibility.
Overall, mining light towers play a crucial role in ensuring the safety and productivity of mining operations by providing adequate lighting in challenging work environments.
