Thermally conductive polycarbonate helps beat the heat in LEDs

Reducing heat and optimizing design

From time to time a technology emerges that completely transforms an industry. LED technology is one of the most disruptive technologies in the lighting market with almost no alternative.

Covestro’s thermally conductive polycarbonates help beat the heat in LED heatsinks for replacement lamps or next-generation luminaires.

Task

Lighting designers and manufacturers need to stay abreast of the changing market landscape, integrating the latest LED technology and materials to create next-generation lighting applications that optimize efficiency and design.

Challenge

While LEDs are more efficient than incandescent bulbs, they still emit energy in the form of heat. This heat must be dissipated via cooling elements to ensure a high light yield and long service life for the lamps. To create effective cooling elements, manufacturers need materials that can beat the heat.

Solution

Covestro’s thermally conductive polycarbonates are used as an alternative to metals in secondary optics, diffusors, reflectors and heatsinks for LEDs. Makrolon® TC8030 polycarbonate provides thermal management with almost half the weight of aluminum. Because the thermoplastic is injection molded, designers have freedom to create non-traditional shapes, use in-mold decoration and optimize joining techniques. Covestro worked with Finnish partners to explore the technical possibilities of this material.
