Elliptical diffusers incorporate two different angles in order to spread light asymmetrically and diffuse one axis more than the other. Elliptical angle diffusers are help lighting designers highlight a specific area more than another area. Our standard elliptical diffuser angles for lighting class include 80° × 50° and 60° × 10° and are commonly used in hallways and specialty lighting to highlight a specific area. Stairway lighting is a good example of how our elliptical angles can highlight the walls but place more light toward the stairs for obvious safety reasons. Extreme elliptical angle, or linear, diffusers such as our 60° × 1° (i.e., 60° along the width and 1° along the length) are commonly used in wall washing, wall grazing, and cove lighting applications where the beam angle must not increase in one axis. We have a helpful blog that covers our extreme angle diffusers in more detail.

How does a Luminit's LED hiding film help lighting designers and lighting manufacturers? Luminit diffuser sheets and films “clean up” and shape a light beam to suit a particular purpose, which makes it possible to achieve a smooth appearance or use fewer LEDs for the same effect. 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, meaning less light loss compared to other diffusers. The above picture demonstrates options for LED strip diffusion and the effects of a 60° x 1° elliptical Light Shaping Diffuser® on an LED strip light. On the left are the bare LED diodes, and on the right are the same diodes with our light diffuser in front. The light is shaped by spreading the horizontal radiation 60° only 1° in the vertical direction (shown horizontally here). The result is the elimination of hotspots on LED lighting as well as CCFL, fiber optic and laser light sources, and a smooth, unbroken strip where the diodes are not individually visible.

The retina is lined with many millions of photoreceptor cells that consist of two types: 7 million cones provide color information and sharpness of images, and 120 million rods are extremely sensitive detectors of white light to provide night vision. The tops of the rods and cones contain a region filled with membrane-bound discs, which contain the molecule cis-retinal bound to a protein called opsin. The resulting complex is called rhodopsin or "visual purple".

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 a conventional LED light diffuser. Holographic Light Shaping Diffusers® offer superior optical transmission between 400nm and 700nm. Depending on the angle of distribution, Luminit LED light diffusers achieve between 85% and 92% transmission efficiency. The low backscatter of the diffuser 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 Light Shaping Diffuser® structure incident to the light source.

There's a reason Luminit is one of the leading light diffusing manufacturers in the world. We have the largest catalog of LED optical diffuser sheets and light bending material as well the most angles and formats available to diffuse LED lighting for architectural environments, bio-medical illumination, semiconductor metrology, aerospace, automotive, laser and display applications. Our optical 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.

You may not see the technology behind a Luminit Light Shaping Diffuser®, but you'll notice the effects of our optical diffusion lenses and light shaping diffuser film for LEDs. 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 lighting diffusers is remarkably efficient, so high efficacy fixtures are possible. Many of our customers use Luminit diffuser sheets to diffuse LED strip lights to hide hotspots and produce a more uniform, homogeneous appearance. We also have the largest library of circular and elliptical beam angles in the world, ranging from 1° to 100° so there is an angle to tackle just about any application.

The light image is mapped on the surface of the retina by activating a series of light-sensitive cells known as rods and cones or photoreceptors. The rods and cones convert the light into electrical impulses which are transmitted to the brain via nerve fibers. The brain then determines, which nerve fibers carried the electrical impulse activate by light at certain photoreceptors, and then creates an image.

Vision is such an everyday occurrence that we seldom stop to think and wonder how we are able to see the objects that surround us. Yet the vision process is a fascinating example of how light can produce molecular changes. The retina contain the molecules that undergo a chemical change upon absorbing light, but it is the brain that actually makes sense of the visual information to create an image.

As the protein changes its geometry, it initiates a cascade of biochemical reactions that results in changes in charge so that a large potential difference builds up across the plasma membrane. This potential difference is passed along to an adjoining nerve cell as an electrical impulse. The nerve cell carries this impulse to the brain, where the visual information is interpreted.

In human eyes, rod and cones react to light stimulation, and a series of chemical reactions happen in cells. These cells receive light, and pass on signals to other receiver cells. This chain of process is class signal transduction pathway. Signal transduction pathway is a mechanism that describe the ways cells react and response to stimulation.

The reaction above shows Lysine side-chain from the opsin react with 11-cis-retinal when stimulated. By removing the oxygen atom from the retinal and two hydrogen atom from the free amino group of the lysine, the linkage show on the picture above is formed, and it is called Schiff base.

Light is one of the most important resources for civilization, it provides energy as it pass along by the sun. Light influence our everyday live. Living organisms sense light from the environment by photoreceptors. Light, as waves carry energy, contains energy by different wavelength. In vision, light is the stimulus input. Light energy goes into eyes stimulate photoreceptor in eyes. However, as an energy wave, energy is passed on through light at different wavelength.

Our Light Shaping Diffusers® are bending, shaping and enhancing light beams in automotive lighting, exterior/interior lighting, in stages and concert halls, projection systems, monitors and displays, bar code scanners, and more. Our LED diffusers are sculpting light in some of the world's most famous landmarks.

The molecule cis-retinal can absorb light at a specific wavelength. When visible light hits the cis-retinal, the cis-retinal undergoes an isomerization, or change in molecular arrangement, to all-trans-retinal. The new form of trans-retinal does not fit as well into the protein, and so a series of geometry changes in the protein begins. The resulting complex is referred to a bathrhodopsin (there are other intermediates in this process, but we'll ignore them for now).

Luminit's Light Shaping Diffuser® is available in three type of angles: circular, elliptical, and extreme angle elliptical (also called linear). Circular angle diffusers are popular across multiple industries and spread a light source into a wide circular pattern depending on the angle selected. Our standard angles include 80°, 60°, 40°, 30°, 20° 10° and 5°. That is, if you purchase a 40° circular diffuser, the beam will be spread 40 degrees in every direction. This makes circular diffusers a popular choice for spotlights, downlights, flashlights, etc., where the light beam of LEDs is narrow (i.e., directional).

Light energy can convert chemical to other forms. Vitamin A, also known as retinol, anti-dry eye vitamins, is a required nutrition for human health. The predecessor of vitamin A is present in the variety of plant carotene. Vitamin A is critical for vision because it is needed by the retina of eye. Retinol can be convert to retinal, and retinal is a chemical necessary for rhodopsin. As light enters the eye, the 11-cis-retinal is isomerized to the all-"trans" form.

Luminit diffusers are popular in indoor and architectural lighting and can be found in some of the world’s most famous building, bridges, and structures. Our unique technology is also instrumental in high tech, display and automotive applications where we provide highly specialized Light Shaping Diffusers® and linear micro-prismatics.

Light Shaping Diffusers® 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 Moiré, color over-angle, and precise angular beam control.

Circular, elliptical, and extreme elliptical diffusers not only provide precise beam angle control, but our diffusers homogenize LEDs and fluorescent lamps and clean up striations for pleasing, human centric lighting.
