LED-based edge-lit illumination

Global Lighting Technologies (GLT) is offering its range of LED-based edge-lit illumination solutions beyond LCDs, keyboards and keypads and into areas of egress lighting and general illumination.

GLT is enhancing the advantages of LED illumination with a new range of edge-lighting solutions utilizing high-efficiency LEDs that focus the light into a high-performance backlight, or light guide.

Because the LEDs are located on the edge of the light guide, there is better optical control for color and uniformity, fewer LEDs, better repeatability, and the thinnest possible lighting solution.

New solutions include edge-lit backlighting units for exit signs and all manner of egress lighting. GLT has also entered into the general illumination/solid-state lighting market with new edge-lit illumination for downlights such as task lights and troffers.

GLT continues to provide BLUs for LCDs, keyboards and keypads utilizing the most efficient LED-based edge lighting and the slimmest BLUs available for maximum brightness with optimum uniformity, superior color mixing and a smaller number of widely spaced, high-output LEDs with low-cost manufacturing and quick turnaround.
