Although tertiary optics or “diffusers” have virtually endless applications, beam shaping remains one of the most popular applications in lighting design, particularly with LEDs. Controlling the shape, size and distribution of light is the cornerstone of Luminit technologies, and we’re taking beam shaping to new heights with our patented Light Shaping Diffusers.
What Does A Light Shaping Diffuser Do?
A scientific definition of a Light Shaping Diffuser would be something like “a holographically-generated surface relief pattern copied on to a surface.” Taking the tech talk down a notch, Light Shaping Diffusers are micro-structures embedded on a substrate that can manipulate light by changing the direction of its energy. The diffusion control of Luminit diffusers is so precise that angular beam control is possible. How does this help engineers and lighting designers? Light Shaping Diffusers “clean up” and shape a light beam to suit a particular purpose.
Light Shaping Diffusers in the Real World
Beam shaping translates to all kinds of clever and helpful applications from highly scientific to automotive tail lights and running lights, to stage and decorative lighting. For example, Luminit Light Shaping Diffusers can manipulate the shape of a circular LED beam into a variety of elliptical shapes and sizes or stretch the beam in a certain direction. The benefits are significant in indoor and outdoor lighting because it allows the beam to target the area of interest without wasting light and energy. Stretching a beam of light allows lighting designers to project a long line of light on a wall or floor with greater efficiency than traditional spread lenses.
Aircraft makers are discovering the benefits of Luminit LSDs in reading lights where beam shaping can direct light on the user without spilling light onto other passengers. In addition, some of the world’s most famous museums use the beam-shaping quality of Luminit LSDs to spotlight only the artwork and not the floor or the wall it hangs on, creating a much more dramatic visual and, of course, efficient use of light.
