As demand for energy-efficient light-emitting diode (LED) fixtures continues to grow, manufacturers are responding with a larger selection of high-quality LED lighting options. To bring these products to market, manufacturers are seeking materials that not only offer design freedom, but which are also tough, reliable and feature a strong property profile.
Line-Voltage Linear LED Engine
Product: Makrolon® FR7087
Polycarbonate from Covestro has become a go-to thermoplastic for rigorous LED lighting applications, such as TerraLUX Illumination’s Line-Voltage Linear LED Engine. Light engines – composed of one or more LED modules, an LED driver and a heat sink -– are used in new and retrofit applications, including indoor and outdoor wall sconces, wall packs, surface-mounted ceiling fixtures and recessed step and wall lights.
This TerraLUX LED engine is a fully integrated, self-contained LED solution, which is AC-mains compatible, dimmable, and requires no additional drivers or special sockets.
TerraLUX uses Makrolon® FR7087 polycarbonate, a medium-viscosity, easy-release grade from Coverstro, for the product’s lens. This grade is also ultraviolet (UV) stabilized, flame retardant (UL 94 flame rated 5VA at 3.0 mm) and is typically processed by injection molding.
The material’s flame rating, light transmission and impact properties, combined with Covestro’s technical expertise, made it a good fit for this demanding application.
In addition, Makrolon FR7087 gave TerraLUX the design freedom necessary to create an integrated LED linear light engine that offers an IP-65 rating, is UL-listed for retrofit solutions and offers in-field durability – all while maintaining maximum light output and efficiency.
The main properties of Makrolon® FR7087 polycarbonate are:
- Easy release
- Medium viscosity
- Flame retardant (UL 94 flame rated 5VA at 3.0 mm)
- Ultraviolet (UV) stabilized
- Good impact resistance
- High clarity
