Covestro, formerly Bayer MaterialScience, is committed to modern and energy-efficient lighting technologies such as LED and has established a wide and diverse range of products for this field. One area of focus is the thermally conductive polycarbonate Makrolon® TC8030. It ensures a good thermal management, but offers significantly more freedom of design than aluminum, which is commonly used for this purpose.

Developing innovative and sustainable solutions for global challenges is, and will remain, a core task of Covestro, formerly Bayer MaterialScience. This also applies to lighting, which presently accounts for around 15 percent of the world’s energy consumption and five percent of greenhouse gas emissions. According to estimates by the UNEP Global Efficient Lighting Forum, switching to energy-efficient lighting could reduce this worldwide energy requirement by more than one thousand terawatt hours (TWh) each year, thus reducing the associated CO2 emissions by roughly 530 million metric tons(1).

Covestro therefore is committed to modern and energy-efficient lighting technologies such as LED and has established a wide and diverse range of products for this field. The focus of the company’s appearance at the 5th International LED professional Lighting Symposium + Expo in Bregenz, Austria, from September 22 to 24 is on the latest developments from Covestro for LED lighting technology.

LED lamps offer numerous advantages, particularly in combination with high-performance plastics such as the polycarbonate Makrolon®. Available in granules, sheets and films, it has a wide range of uses in lenses and optics, light guides, diffusers, reflectors, cooling elements and housings.

Focus on heat management
Despite some improvement with respect to the efficiency of LEDs, the lamps have still not yet reached the level of efficiency theoretically possible because a portion of the energy is given off in the form of heat. This heat must be dissipated via cooling elements in order to ensure a high light yield and long service life of the lamps.

For this application, Covestro has launched the special, thermally conductive polycarbonate Makrolon® TC8030 (TC stands for “thermally conductive”). “Compared with the aluminum typically used, the plastic stands out for its combination of good thermal conductivity and greater design freedom,” says Dr. Klaus Reinartz, Covestro Marketing Manager for LED Lighting in the Europe, Middle East, Africa and Latin America region, during a presentation at the LpS symposium. “The easy and efficient production via injection molding enables a whole new generation of cooling elements.”

The plastic has good thermal conductivity behavior similar to that of aluminum, but weighs less and is therefore well-suited for lighter-weight LED lighting solutions. Additional thermally conductive Makrolon® grades from Covestro are set to be launched soon.
