Direction Turning Films can be combined with Light Shaping Diffusers to shape and homogenize the beam in addition to changing the direction. The beam can be shaped in a circular or elliptical pattern dependent on the diffuser angle chosen. These light bending films enable off-axis placement of the incoming beam when direct line of sight is impractical. Applications include LED lighting, avionics displays, traffic signs/displays and LCD backlights. They are also used to change the light beam direction to light a wall, walkway or other lighting target.

This will depend on the secondary optics you are using; however, the following chart can help determine the resultant beam angle.

FWHM is an abbreviation for Full-Width Half-Maximum which is the angle of diffusion that would be seen after a collimated laser passes through the diffuser.

Light Shaping Diffusers® are micro-structures pseudo-randomly embedded on a substrate (such as film) which perform optical diffusion. When applied to a lighting structure, the Light Shaping Diffuser® can manipulate light by changing the direction of its energy. This allows our Light Shaping Diffusers® to clean up and shape a light beam to suit a particular purpose.

We recommend our glass diffuser for high temperature and high power laser applications. This diffusion material is stable up to 500 degrees Celsius and offers high transmission and high quality homogenized light for laser and other high damage threshold applications.

Yes, Luminit Light Shaping Diffusers® are available in various circular and elliptical angles in pre-cut sheet format for lower volume applications.

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.

Since our microstructures are random and non-periodic, the Light Shaping Diffuser® is not wavelength-dependent, so it works well from 400nm to 700nm.

The transmission efficiencies of Luminit optical diffusers are rated between 85-92% (depending on the angle). This very high-efficiency rating is due to the fact that our technology is based on diffractive microstructures. Smaller angle diffusers have the highest transmission.

Yes, Luminit optical diffusion films are so precise that beam shaping is possible. Our patented holographic master recording process allows a variety of circular and elliptical light patterns. Standard circular angles range from 0.5˚ to 100˚ FWHM. A wide variety of standard elliptical angles, ranging from 10˚x0.2˚ to 95˚x35˚, are available.

We suggest you handle the diffuser with clean latex gloves. High angle diffusers are very prone to damage due the height of the microstructures. They can be cleaned carefully using optical wipes and ethanol using the industry-standard “drop and drag” technique.

Flexi Neon offers highly durable, flexible and diffused linear LEDs built for harsh environments. The range comprises of IP67 Silicone encapsulated and IP68 PVC encapsulated solutions for indoor/outdoor, underwater, high-temperature, ATEX, and grazing applications.

Light Shaping Diffusers® are often applied in architectural lighting, can lights, decorative lighting, pool lighting, set/event lighting and wall wash lighting where the effects of the Light Shaping Diffuser® can be quite dramatic. LED Light Shaping Diffusers® are also used in illumination systems such as aircraft inspection lights; backlit systems such as cellphone and PDA displays; LCD screens and more. One of the most common uses for our light diffusers is to eliminate hot spots on LED light strips.

The Rigid Grazer range offers tailored solutions for seamless wall grazing applications, featuring two core variants: Maxi and Nano.

Luminit Monolithic Glass Diffusers are made with an etching process, while our Glass on Glass light diffusers have pseudo-random microstructures that are cast and cured onto the surface of the glass. Temperature is one of the factors that differentiate the two. Our Glass on Glass diffusers are stable up to 500° C and are suitable for high-temperature laser applications. Monolithic glass is also rated for high temperature but is more suitable for lighting applications.

The Flexi Panel range consists of ultra-thin, flexible LED light sheets designed for direct adhesion to flat or curved surfaces.

Our blue protective film is used to protect the diffuser during transit to reduce the chances of scratches. We advise customers to remove the film within three months of arrival. The reason for this is that there is a chance that the adhesive on the film can cure or harden and stick to the diffuser.

Yes, our Light Shaping Diffusers comply with RoHs standards. An environmental compliance statement can be downloaded here.

Because we replicate our holographic LED diffusers directly onto rigid panels instead of through a lamination process, our LED diffuser panels will not become brittle, peel or yellow over time.

No, since our technology is based on a surface relief pattern, these parameters are not dependent on the thickness of the substrate. However, there are inherently additional transmission losses if very thick substrates are utilized (Beer’s Law).

There are currently two different types of DTF products, one is a 20⁰ bend-off axis material for visible or white light and the other is a 10⁰ bend-off axis for 810nm (IR) LEDs.

Yes, our lighting diffuser film is approved by AMECA as meeting the three-year weathering test of SAE J576 for plastics used in optical lenses and reflectors on motor vehicles.

The diffuser has improved transmission characteristics if the microstructure side is facing the light source, but it has better source hiding characteristics if the microstructure side is facing away from the light source.

UGR stands for Unified Glare Rating and is an international standard that measures glare in lighting fixtures and designs. UGR standards are used by lighting designers and manufacturers to mitigate glare from artificial lighting.

This depends on the angle of divergence and spacing of the light sources. With 110° Field of View, surface mount LEDs, the relationship is around 1:1. That is, if the LEDs are spaced 1 inch apart then you will need a little more than 1-inch distance from the LEDs to our largest diffuser angles. Here is an illustration demonstrating the ratios with various angle diffusers.

Yes, Luminit Light Shaping Diffusers® are commonly used as an LED strip light diffuser to eliminate the hotspots without a significant reduction in the amount of the light, provided that the diffuser is placed a sufficient distance from the LEDs. A rule of thumb is that the diffuser must be at least as far away from the LEDs as the LEDs are spaced apart.

We have models available for Zemax OpticStudio on our DLL downloads and offer our models libraries such as Photopia, LightTools, and Lucidshape. Visit our Modeling/Simulation page for more information.

Luminit’s DTF (Direction Turning Film) is a non-symmetrical linear micro-prismatic that imparts a 20-degree shift in the angle of a semi-collimated light source. The DTF works well with LED light sources that utilize secondary optics. Some applications include recessed can lights to allow for more wall washing, pathway/stair lighting to reduce glare and increase ground illumination, and pool lighting to increase illumination of the bottom.

Birefingence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light. In LCD screens, birefringence can create unwanted optical artifacts such as Newton's rings and moire. The high transmission efficiency of Luminit diffusers as well as the ability to homogenize a light source can preserve polarization and eliminate birefingence.

The light will follow the specular ray. When the AOI is non-zero, the distribution center will follow the transmitted direction. The Zemax models we provide offer a good prediction of the ray distribution. You can see the light path and distribution patterns.

For indoor applications, a Light Shaping Diffuser® can last as long as the light structure. For outdoor applications, measures may need to be taken to prevent  yellowing of the film due to exposure to the sun. For outdoor lighting applications, Luminit offers an optional UV-stable substrate to help prevent yellowing.

Luminit replicates diffusers on polycarbonate and acrylics (PMMA). We can also replicate our diffusers on glass products.

The LEDFlex control drivers are designed to integrate with the increasing range of available controllers, offering seamless and flicker-free dimming.
