According to statistics from the High-tech LED Industry Research Institute (GLII), more than 65% of global LED applications in 2012 were concentrated in China. However, despite the size of China's local LED industry, China still has bottlenecks in LED packaging and peripheral parts processing technology, and high-end materials still rely mainly on imports.
The price of LED lamps has always been high, several times or even dozens of times higher than ordinary lamps. This is one of the reasons. LED lighting needs to start from the source of materials in order to enter the ordinary people's home.
Local companies missed new materials
As an important part of the whole lamp structure, the heat sink plays no less important role than the chips and lamp beads upstream of the industrial chain. However, the current radiator market is mixed, and the quality of the heat-dissipating products is also uneven. At present, the heat-dissipating materials of most LED lamps on the market are mostly made of aluminum or aluminum alloy materials, which are not only cumbersome but also have poor heat dissipation effects.
Some people in the world have successfully developed high thermal conductive plastics to replace metal materials. The thermal conductive plastics developed by American Coolpolymer Company based on ABS, polyamide, liquid crystal polymer, polyetheretherketone, etc., can increase the thermal conductivity by up to 100 times.
China's research and development based on aluminum materials, such as heat pipe and microchannel heat dissipation technology, is comparable to the international level, but as a new high-value-added and high-margin heat dissipation material field, there is always a lack of sufficient strength to compete with it.
“Metal, ceramic and carbon materials with excellent thermal conductivity are difficult to adapt to the needs of the development of new products and new technologies due to poor electrical insulation, poor processing and forming properties, etc. Therefore, the development of new thermal conductive composite materials has become hot spot."
As a Chinese force, Gaoku Nano Technology has been committed to the development and promotion of new polymer materials with special properties.
In 2013, with its own unique research and development technology, thermal plastic materials began commercial production. It is understood that high thermal conductive plastic is a high-performance, electrical insulation, environmentally friendly and flame-retardant functional composite material developed for LED heat dissipation problems.
Efficient heat dissipation and product safety and light weight. Thanks to the efforts of the high-tech R&D team, Gaokuo's products have been widely accepted by LED industry customers including internationally renowned manufacturers. The consistency and quality stability of Gaokuo's products in large-scale production have been well received by customers.
High thermal conductivity, integrated injection molding
The heat dissipation of LEDs is measured by thermal resistance, which is mainly caused by thermal resistance, convection and radiation. If the shape of the product is determined, the temperature of the exterior and the temperature of the surrounding environment are determined, its convection effect is basically similar, and the appearance can be very flexible. With the principle of high-heat-conducting composite material embedded in aluminum design, Hefu Technology utilizes the high heat dissipation of thermal conductive composite materials, better thermal conductivity and electrical insulation properties, and also utilizes the high thermal conductivity of stamped aluminum for effective control. Thermal resistance of the heat dissipation system.
High thermal conductivity composite materials have three characteristics in LED lighting, one is good thermal conductivity; the second is good electrical insulation; the third is good molding processing performance, similar to conventional materials.
