It is understood that the accelerated development of the LED lighting market has brought huge business opportunities to the heat dissipation industry of supporting materials, especially the market demand for LED street light cooling housing kits that are just driven by the policy has surged. With the rapid development of the current commercial lighting and outdoor high-power lighting market, the market demand for LED lamp cooling housing is also rapidly increasing.
It is understood that as the carrier of the light source, the heat dissipation design of the lamp is crucial for the LED to exert its advantages. If the heat dissipation efficiency of the luminaire is designed to be high, it can not only prolong the service life, but also reduce the weight of the luminaire and expand its application range. On the contrary, it will affect the LED's advantages and even become the bottleneck of its application.
In LED lighting systems, the heat dissipation problem of LEDs is a technical challenge. The outstanding features of LEDs are small size, compact structure and easy to embed various lamps. The US energy department has said that every 35 degrees increase in LED products can shorten its service life by more than 42%. Increased operating temperatures can also cause safety issues, including electric shock, fire risk and eye injuries. The emergence of thermoplastics is gradually replacing aluminum alloys in the field of heat dissipation and heat-sensitive components in the field of lighting. At the same time, specialty thermoplastics have proved their advantages in metal replacement applications with their own excellent characteristics.
For the lighting system, since the heat dissipation method is easy to combine with the structure of the lamp, the structure is relatively simple, and no additional power consumption is required, and passive heat dissipation is used for comprehensive consideration of processing, material cost, maintenance factor, and the like. The overall cost is relatively low. At present, the mainstream direction is passive heat dissipation. By properly designing the heat sink to meet the heat dissipation requirements of the lighting system to the utmost, the cost is maximized. Mr. Wu, general manager of Polyplastics Asia's engineering plastics division, said that thermal plastics are superior to cast aluminum in thermal simulation tests. Among them, the surface area of ​​heat exchange is increased by 25%, and the weight can be reduced by 9%.
Throughout the LED lighting accessories industry, the manufacturers are numerous, but the scale is not large. Among them, there are many workshop-type roughing-type enterprises, and there are few manufacturers specializing in producing finished parts for lighting finished products. In order to reduce the cost of conventional expenses, many manufacturers of heat-dissipating components have “scraping and cutting materials†for all aspects of mold opening, design and procurement at the expense of quality.
In contrast, large chemical and agricultural companies have not relied on “scraping and reducing materials†to increase their market share. Most companies have accepted biomaterials and invested in this area. As the world's leading supplier of specialty polymer materials, services and solutions, PolyOne places great value on organic materials, especially biomaterials, and has developed innovative polymer solutions for several key components of LED lighting, including PCs and PCs. /ABS, ABS and other engineering materials, pigments and additives in the outer shell part, thermal conductive engineering materials used for heat treatment and thermal diffusion in the optical industry.
The heat-dissipating materials industry and even the entire LED industry have been in a critical period. Industry experts expect that the industry will be able to complete the reshuffle from the second half of this year to the first half of next year, and eventually the scale enterprises will be retained, and the overall shipments will be further improved. The trend is stable and the industry standards are more standardized.
Looking at the current thermal conductive plastics in the industry, the thermal conductivity is not very high. The thermal conductivity of a typical price within 30 yuan is generally between 1.0-1.3W/MK. If the thermal conductivity needs to be increased, the price will increase. With the rapid increase in the popularity of LED lighting systems in recent years, thermoplastics will occupy more market share in the future.
