Makrolon® TC8030 Polycarbonate for LED Lamps Case Study

Clear choice for energy-efficient lighting

Latest material solutions for heat management of LED lamps

According to the UNEP Global Efficient Lighting Forum, Lighting accounts for 15 percent of the world’s energy consumption and 5 percent of greenhouse gas emissions. Switching to energy-efficient lighting reduces the worldwide energy requirement by over one thousand terawatt hours each year and CO2 emissions by 530 million metric tons.

LED lamps are one energy-efficient lighting option, offering numerous advantages, particularly in combination with high-performance plastics such as Makrolon® polycarbonate from Covestro. This high-performance plastic has a wide range of uses in lenses and optics, light guides, diffusers, reflectors, heat sinks and housings.

Despite improvement with respect to the efficiency of LEDs, the lamps have still not reached the level of efficiency possible because a portion of the energy is converted into heat. This heat must be dissipated via cooling elements to ensure a high light yield and long service life of the lamps.

To answer this industry need, Covestro has launched Makrolon® TC8030 thermally conductive polycarbonate. The plastic has good thermal conductivity 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.

The main properties of Makrolon® TC8030 polycarbonate are:

  • Thermally conductive
  • Design freedom
  • Light-weight
