Lumex (Palatine, IL) has announced TransBrite™ Halo Ring™ light pipe technology for LEDs. The pipes come in both standard and custom formats, created with ray trace software and 3D CAD/CAM models for optimum light transmittance.
The patented Halo Ring™ light pipe, which is mounted directly to the panel, allows users to add visible dual-color indicator lights on switches. Its dual-ring and gasket design features a protective rubber layer in front of the indicator light, making the technology splash- and water-proof. The Halo Ring also has a 120° viewing angle and an extended temperature range of -40°C to 100°C. The RoHs-compliant Halo Rings, available in custom sizes from 10mm to 20mm, come in blue, white, red, yellow, and green.
