GLT Introduces New Light Guide with Different Bi-Polar Emission Pattern

This enables lighting fixtures to emit light upward and downward using a single light guide with LEDs on one or two edges, while varying the distribution pattern from top to bottom.  As demonstrated in the images and polar plot, one such option is a light guide that will produce a “batwing” distribution in the upward direction, while maintaining a more direct distribution in the downward direction.  This distribution would allow proper illumination of a table or desk below the light guide while, at the same time, allowing the indirect lighting of the room from the upward distribution.  Other options include more Lambertian distributions downward for more diffuse lighting as well as varying output angles for the upward distribution.

GLT can also design custom light guide assemblies in a “cartridge” format based on a customer’s specific requirements, allowing them to be used as a standardized light source in a variety of fixtures.
