Light Shaping Diffusers at Work
You may not see the technology behind a Luminit’s LED Light Diffuser, but you'll notice the effects of our optical diffusion lenses and light shaping diffuser film. Light Shaping Diffusers expand what’s possible with light using Luminit's advanced holographic beam shaping technology. Unlike conventional plastic light diffusion panels, Luminit's patented technology shapes light energy with holographic patterns embedded on polycarbonate film or rigid sheets. These patterns create a pseudo-random surface that can manipulate light by changing the direction of its energy. Available in both circular and elliptical formats, the diffusion ability of Luminit led light diffusers is remarkably efficient so high efficacy fixtures are possible. Many of our customers use a Luminit diffuser sheet for led lighting to hide hotspots for a more uniform appearance.
The World's Best Hiding Power
How does a Luminit diffuser for led lights help lighting designers and lighting manufacturers? Luminit broadband diffuser sheets and films “clean up” and shape a light beam to suit a particular purpose and that’s big. For example, LEDs are very efficient but hot spots and uneven light distribution remain a problem for lighting professionals. Our Light Shaping Diffuser sheets homogenize and shape the light with 85% to 92% transmission efficiency. The above picture demonstrates options for LED strip diffusion and the effects of a 60° x 1° elliptical LSD on an LED strip light. The light is shaped by spreading the horizontal radiation 60° only 1° in the vertical direction. The result is the elimination of hotspots on LED lighting as well as CCFL, fiber optic and laser light sources.
There's a reason Luminit is one of the leading light diffusing polycarbonate sheet manufacturers in the world. We have the largest catalog of LED light shaping diffuser sheets and light bending material as well the most of angles and formats available to diffuse LED lighting for architectural environments, bio-medical illumination, semiconductor metrology, aerospace, automotive, laser and display applications. Our diffusion technology is based on a very thin microstructure on top of the clearest substrates available. The transmission efficiency of our thin film and thick rigid diffusers is practically equivalent.
Light Shaping Diffuser use surface relief structures that are replicated from a holographically-recorded master. These pseudo-random, non-periodic structures can manipulate light by changing the direction of its energy. The result is the elimination of Moire՛, color over-angle, and precise angular beam control.
Luminit Light Shaping Diffusers Have Capabilities Others Do Not
High Transmission Efficiency
Because the principle of surface scatter is used instead of volume or bulk scatter, our LED diffuser sheets have a much higher transmission efficiency (~92%) than conventional plastic light diffusers. Holographic Light Shaping Diffusers offer superior optical transmission between 200nm and 1500nm. Depending on the angle of distribution, Luminit LED light diffusers achieve between 85% and 92% transmission efficiency. The low backscatter of the LSD structures are anti-reflective in nature and utilize light that would otherwise be wasted due to Fresnel loss. A clear piece of polycarbonate substrate is 89% transmissive. With a Luminit LED light diffuser added, transmission improves to 92%. Note that Luminit measures transmission utilizing an integrated sphere with the LSD structure incident to the light source.
