Alternative technology for LED aluminum heat sinks, GE Lighting intends to adopt

For cost reasons, today's LED lighting commercial applications (such as LED street lights) basically use aluminum radiators, which are the main source of weight for LED lighting systems. Today, Shanghai HELF (Hefu New Material Technology Co., Ltd.) has developed a high thermal conductivity composite polymer material Therpoxy, which can replace the aluminum radiator for LED lighting. The weight of the LED radiator formed by it can be lighter than that of the aluminum radiator. 3 or more, the cost is reduced by more than 35%, and the overall heat dissipation performance is comparable to that of pure die-cast aluminum.

Therpoxy has passed UL and SGS material performance certification, and its other main features include: 1) surface electrical insulation, breakdown voltage up to 4000V; 2) ultra-high long-term use temperature (RTI) over 130 degrees; 3) processing Short cycle, fast delivery, low temperature processing and molding; 4) can be customized according to customer needs; 5) potential multi-component integration and integrated design

Cooperation between HELF and GE Lighting, Toyota Synthetic and other companies is already underway. Now HELF's production capacity is 20 tons / month, and it is expected to reach 50 tons / month at the end of this year. At the same time, HELF has developed an integrated thermal solution for this material in LED lighting. To provide an effective solution to significantly reduce the cost of LED lighting.

HELF has been committed to the development and promotion of new polymer materials with special properties. The company can provide targeted solutions according to customer requirements. It has the ability to provide the development of special-purpose polymer composite materials, as well as the design and manufacture of molds for related products and the mass production of products.
