Light Guides for LED Fixtures

The transition to LEDs in lighting is well underway, with a broad range of fixtures and lighting applications taking advantage of the inherently green characteristics of solid-state lighting. Beginning with edge-lit back lighting, Rambus has pioneered a light guide-based design that enables a new level of styling, efficiency and control for LED lighting.

We combined TruEdge™ LED Coupling – techniques to maximize the amount of light emitted from the LED to the light guide – with MicroLens® optics – tiny 3D features that control how the light comes out of the light guide – to create highly-efficient and cost-effective fixtures with unparalleled design flexibility.

LED Fixture Light Guides

What’s Included

Our offering includes customizable light guide design and manufacturing solutions with expert optical engineering support. The light guides are available as off-the-shelf or customized designs that are optimized to specific customer and application requirements by varying the size, shape and density of the MircoLens optics. Manufactured by our global lighting partners or at our state-of-the-art facility within the US, our light guides can support both flat and curved designs in a broad range of high volume lighting applications.

In addition, complete fixture prototype designs that combine our optical innovations, design engineering and manufacturing support services are also available to lighting system companies and fixture manufacturers worldwide.
