Covestro launches polycarbonate for LED lamps in extreme environments

LED light source has the advantages of energy saving and long life.
It is an economical light source and is widely used in buildings, vehicles, street lamps and other fields
.
The design of light guides, reflectors, diffusers and lenses ensures optimal use of LED lamps
.

Covestro has spent years developing custom combinations of transparent, translucent, reflective, and thermally conductive and flame-retardant grades of polycarbonate plastic to meet these needs
.

swimming pool LED lighting

LED lights operating in water have special requirements for related materials
.
In cooperation with the Brazilian swimming pool equipment supplier Ecopyre Lighting, Covestro has developed a comprehensive solution using the thermally conductive polycarbonate Makrolon® TC
.
It is characterized by providing high dimensional stability during the manufacture and operation of the luminaire, thus preventing water ingress
.

The letters "TC" in the model name stand for "thermal conductivity", indicating that the plastic has good thermal conductivity
.
This makes it ideal for efficient thermal management – ​​like other types in the TC portfolio, where the heat generated by the LEDs can be well dissipated
.
In addition, the plastic meets the chemical resistance requirements for use in swimming pool water
.

Explosion-proof LED light lens

The highly transparent product Makrolon® is even suitable for lenses in explosion-proof lamps, as evidenced by a recent case study with safety technology supplier R.
Stahl
.
These lamps comply with EU ATEX Directive 1 Category 2 and 3 (for use in Zones 1 and 21, or Zones 2 and 22) and are suitable for use in industrial environments where highly explosive dust and gas atmospheres may occur during normal operation
.
These environments include oil platforms, refineries, and certain chemical plants
.

R.
Stahl AG, Germany's leader in safety technology in potentially explosive atmospheres, is looking for an optical material solution for LED safety lighting that can be used worldwide
.
It was chosen because the transparent plastic Makrolon® can realize light focusing optics and is suitable for high temperature of 60 to 85 degrees Celsius
