Application fields of UFO industrial and mining lamps and selection of thermal grease

At present, LED lighting can be said to be thriving. Advertisements for UFO industrial and LED energy-saving lights are everywhere in the world. Introduce how to save energy and how to be durable. But currently, energy-saving industrial and mining lighting fixtures are rarely used in school lighting systems. The LED lighting system is also a global demonstration project for Z major semiconductor lighting, ranking among the top in the world. More than 8000 LED lighting sources are distributed throughout the corridors and classrooms of the teaching building, and 1500 LED lighting lights are distributed throughout the campus. LED lighting fixtures on roadsides, lakesides, lawns, sports venues, and parking lots have become the fourth generation of light sources after incandescent, fluorescent, and high-pressure gas lamps. Compared with traditional lighting fixtures, LED lighting fixtures can save 60% -70% of electricity, and campus electricity bills can be saved by over 1 million yuan per year. It can be seen that the use and development of UFO industrial and mining lamps need to be strengthened.
Selection of hot grease for UFO industrial and mining lamps
With the development of society, the demand for green lighting for energy conservation and emission reduction is becoming increasingly strong. The main products of green lighting include LED energy-saving lamps, UFO industrial and mining lamps, and other products. However, the quality of LED products in China is currently uneven. A very important reason is that the quality of the heat dissipation paste is not good, and the heat dissipation plate is not enough, resulting in low quality of the lighting fixtures. Attention should be paid to the selection of thermal grease: viscous thermal grease should be used to improve thermal conductivity and extend the service life of UFO industrial and mining lamps; There are many options for diffusion plates, each with its own advantages and disadvantages. Most flat panel lamps use diffusion plates with smooth and foggy surfaces. However, this type of lamp panel will generate a large amount of static electricity during use, and the dust in the emitted gas will adsorb on the lampshade or lamp body, affecting the uniformity of light.
In addition to the driver chip, another key component of the low-voltage LED lamp driver power supply is the Electrolytic capacitor. The working characteristics of high temperature resistant Electrolytic capacitor determine its lifetime. Traditional lamp structures leave little available space. The electrical and physical interface of general lighting fixtures is above the lamp holder, and the power module is between the lamp holder and the lamp bead. Therefore, after the lamp bead is energized, a large amount of heat rises and accumulates in the narrow space of the lamp head, making it difficult to dissipate. At present, the measured temperature of energy-saving industrial and mining lighting fixtures produced by technology is 70~110, so the entire drive power module must be suitable for such a high temperature environment. If the problem of heat dissipation is not solved, it will not only affect the normal operation of the drive power supply and the life of the Electrolytic capacitor, but also lead to the early light failure of the energy-saving industrial and mining lamp beads and affect the life of the entire UFO industrial and mining lamp.
As an indispensable part of power supply, Electrolytic capacitor must be able to work in high temperature environment for a long time, which is a severe test. The structural design and advanced manufacturing technology of Aluminum electrolytic capacitor determine its service life. Aluminum electrolytic capacitor emphasizes long life, high temperature resistance and miniaturization.
