Plastic solutions for LED lighting technology

Transparent optical elements with Makrolon® LED / Efficient cooling with new heat conducting types / Polycarbonate semi-finished products for large-scale lighting concepts
From 18 to 23 March, Light + Building, the world's leading trade fair for lighting technology and building automation, will once again be opening its doors at the exhibition grounds in Frankfurt am Main. At Stand A84 in Hall 4.0, Covestro will be showcasing material solutions based on high-performance polycarbonate for applications in optics, light guides, diffusers, reflectors and heat sinks.

Under the motto "Walk the Way of Light with Smart Materials", the company will be informing visitors about current developments in the targeted bundling, scattering and reflection of LED light, and offers a wide range of polycarbonate granulates, films and sheets.

See and feel the materials
This year, Covestro will use the Light + Building trade fair to present a wide range of material solutions for future efficient lighting to visitors. The Sample Bar gives visitors the chance to see and touch dozens of samples – an ideal way to discover the fascinating characteristics offered by modern plastics.

They also attract the interest of designers. They gain a great deal of freedom, especially when it comes to the functional and individual design of light sources and interiors.

Highly transparent polycarbonate for secondary optics
Makrolon® LED 5102 is a UV-stabilized, highly transparent polycarbonate for secondary optics in the general lighting industry. With its high transparency of more than 90 percent and long lifetime, it outplays major competitor products and existing Makrolon® grades, and enables manufacturers to easily meet the demanding requirements of their lighting customers. Good flowability allows smooth processing specifically in case of larger parts with increased requirements for dimensional accuracy and less sink marks.

New product types for heat sinks
Freedom of design, even lighter weight and easy processing – these are the main features of new polycarbonate types for heat sinks. In exactly these properties, the Makrolon® TC range of products (the abbreviation stands for thermally conductive) offers clear advantages over the conventionally used aluminum. They also facilitate the integration of functions.

Glare-free offices
Glare-free lighting and slim designs are core requirements for the office design of the future. Covestro has tackled this challenge and will be presenting two new transparent solid polycarbonate sheets at the Light + Building trade fair: Makrolon® DX Sky and Makrolon® SX Sharp. Both types have smooth and textured surfaces with special microprismatic optics. Both types are very well suited for the illumination of interiors and are used for example for lamp covers at the workplace.
