Expanding the Luminaire Design Space
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.
With precise LED coupling along with MicroLens® optics – tiny 3D features that control how the light comes out of the light guide – create highly-efficient and cost-effective fixtures with unparalleled design flexibility for wide variety of luminaire applications.
What are MicroLens® Optics
MicroLens® optics are 3-dimensional elements that are embedded into an optical waveguide or film that provide customizable control of uniformity and light direction for superior application efficiency. Using our proprietary optical modeling software and design techniques, the MicroLens features and patterns can be customized to efficiently spread the light across the entire lighting surface, or direct it to specific locations.
The MicroLens optics are embedded directly into the light guide using injection molding, extrusion, or hot embossing processes. With advanced modeling techniques, the depth, shape and density of the MicroLens® features can be optimized to support a broad range of lighting solutions. Light injected at the edge of the light guide is precisely directed using the custom design of the MicroLens® optics.
Our offering includes customizable light guide design and manufacturing solutions with expert optical engineering support. Additionally, our light guides are available as off-the-shelf designs that are optimized to specific customer and application requirements by varying the size, shape and density of the MircoLens optics. Manufactured at our state-of-the art facility near Cleveland, OH, 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.
Our state-of-the-art manufacturing facility near Cleveland, Ohio is home to some of the most advanced optical design and manufacturing capabilities on the globe. At the core of the lighting division’s expertise is the design and manufacture of MicroLens optical technology that enables innovative LED luminaire design. We provide complete design and manufacturing services, from concept to manufacturing to testing to insure that the highest quality product is delivered, down to the micro-scale.
