dcsimg Makrolon® polycarbonate for VLUX Futurix LED Case Study

Smart plastic for LED lighting

VLUX counts on polycarbonate from Covestro for lamp housings

LED luminaires in harsh conditions such as damp and dusty environments need strong, high-performance materials. LED components designed for these conditions need to be tough enough for outdoor use and be able to withstand long exposure all types of weather conditions.

Belgian manufacturer VLUX looked to Covestro for a material solution for its Futurix series of LED lamps designed for industrial and outdoor environments. The Futurix series satisfies the requirements of the IP65 (IP stands for International Protection) safety classification and features outstanding performance qualities.

To achieve a strong, weatherproof, yet inviting lighting system, Covestro specially developed Makrolon® 2207 polycarbonate for the lamp covers in the Futurix series. This diffuse grade of polycarbonate successfully meets the requirements for transmission and half-peak beam angle (HPA), while giving proper consideration to the required wall thickness and complex shape of the lamp covers.

The translucent, white-colored Makrolon® 2207polycarbonate is inherently flame retardant and tough enough to withstand high impacts, enabling the LEDs to endure long exposure to different environmental impacts. The warm, white material produces a pleasant atmosphere without glare.

Furthermore, the thermoplastic material’s low shrinkage and low tendency to warp contribute to the dimensional stability and tightness of the luminaire construction. This made it an excellent choice to protect the LED luminaires against dust and water spray.

The main properties of Makrolon® 2207 polycarbonate are:

  • High toughness
  • Good heat resistance
  • Flame retardant
  • Glass-like transparency
  • High dimensional accuracy and stability
