If you’ve never heard the term sol-gel, you’re not alone, but in the world of materials science, sol-gel is a rock star. An abbreviation for Solution Gel, sol-gel is a well-documented method for creating solid materials from small molecules. By following the sol-gel processing method, scientists can add microparticles or molecules to a solution (sol), and those tiny particles eventually bond to form a gel. Sol-gel is instrumental here at Luminit because it allows us to create specialized optics, such as our…

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.

Getting a light source to behave the way we want it to is not always easy, particularly when mounting/placement constrictions prevent direct line of sight.  Fortunately, advances in optical science offer unique solutions for lighting engineers and designers struggling with less than ideal spaces, and one of the most innovative is Luminit’s Direction Turning Films (DTFs).

The average end-user rarely thinks about the complex stack of components and optical films engineered into displays. Critical to the stack are diffuser films that act as light management components and distribute light uniformly. Luminit Light Shaping Diffusers are often integrated into fixed, mobile and avionics displays to improve uniformity and brightness, enhance viewing angles, and to overcome optical challenges inherent to many displays.

Micro LEDs (mLEDs) are gaining attention in the display industry, particularly for wearable and mobile devices. Ranging in size from 1 to 10 microns and spaced less than a millimeter apart, micro-LED displays are astonishingly bright and more energy efficient than LCDs and OLEDs. While the technology is promising, engineers face challenges when designing mLEDs into small, portable displays such as smart watches where space is limited and resolution is critical. Some key challenges, however, are being overcome with Luminit’s 100° Micro LED Diffuser (MLD).

To help our customers predict scatter patterns of our most common Light Shaping Diffuser angles, Luminit developed a proprietary scatter model for users of Zemax OpticStudio (Professional and Premium versions only). Unlike most conventional optical design programs that provide bulk scatter and surface scatter models based on mathematical probabilities tables that “predict” output distribution, Luminit’s proprietary optical model accurately calculates surface effects so users can choose which angle LSD offers the most optimized performance. This white paper describes the characteristics of…

Luminit scientists and engineers are constantly pushing the boundaries of what our diffuser technology can do with light energy. Our patented surface micro- structures provide customized light shaping and brighter displays which results in more appealing and higher performance products. Round Tip Display (RTD) film is an example of how our Light Shaping Diffuser technology can be used to increase the brightness of displays by making use of refracted and reflected light to recycle otherwise wasted light and direct more light toward the viewer. RTD can provide a brightness gain of 30% to 40…

Many lighting manufacturers recognize the key role tertiary optics (e.g., Light Shaping Diffusers®) play in creating more Human Centric Lighting (HCL) conditions, or lighting that takes into account the emotional and biological needs of humans. Batwing diffusers are an example of tertiary optics that, when incorporated in the design phase, can dramatically increase the light distribution and eliminate distracting central hotspots common to linear light fixtures.

As the demand for smaller and more powerful computers and other electronic devices grows, component suppliers are making their own innovations to keep up with the trend. This is certainly the case in lighting where conventional geometrical optical components such as lenses, mirrors and prisms are being replaced by what is now being coined as “flat optics,” or film-based materials as thin as 50 microns that enable designers to create smaller and more optically efficient products.

Advances in holographic materials, lasers, and digital computing, combined with quickly accelerating AR and VR markets, are breathing new life into the decades-old field of holography. While widespread practical applications for holography have been slow out of the gate, holographically-based products spearheaded  by Luminit are benefitting more industries now than you may think.

While Computer Generated Holography is not a new field, advances in computing technology are bringing new applications for CGHs. If your first thought when you see the words computer generated holography is “Help Me, Obi-Wan Kenobi,” think again. Such futuristic holography is exactly that—futuristic. However, progress is being made in 3D and multi-planar holography, and Luminit’s expertise in this field is helping to re-shape what is possible.

Even before Luminit started to work with tail light manufacturers, I found myself admiring and studying tail light designs during my long drives to and from work in Los Angeles.  Tail lights have come a long way since the incandescent bulb. Back then, designers incorporated secondary collection optics like metalized parabolic reflectors to collect and reflect the light back out of the tail light at the required beam angles and lumens to meet minimum levels set by the Department of Transportation (DOT).  Some the…

Advances in LED technology continue to bring new opportunities for commercial and residential lighting, as well as innovations in digital displays. Existing optical technologies are also benefiting from the LED boom, specifically Holographic Optical Elements or HOEs.  Holographic Optical Elements are holographic images embedded onto a thin, clear photopolymer film that can be applied to glass or acrylic surfaces. When a light source, such as LED, is projected onto the surface, the invisible recorded holographic images come to life. Although the technology has existed for decades,…

Augmented Reality Displays are gaining momentum as more companies recognize the emerging potential of the wearable market. Also referred to as Near to Eye or Near Eye Displays (NEDs), these wearable devices are typically lenses combined with semitransparent beam combiners that create a virtual image in front of the user's field of vision. These displays can be transparent with a virtual image that appears on top of a real world view, such as those used in the Google Glass, or opaque displays often seen in…

Holographic Optical Elements (HOEs) allow scientists to do amazing things with light that would otherwise be impractical with conventional optics. HOEs can redirect images from a light source that is hidden from view. HOEs can also create fully see-through virtual image displays. While the possibilities are practically endless, some of the most exciting display applications of HOE technology are being developed by Luminit scientists for Head-decoupled Displays, Head-up Displays (HUDs), Head- and Helmet-mounted…

Luminit offers the largest library of beam angles, including circular, elliptical, and extreme elliptical angles. Elliptical angles, also called asymmetrical, diffuse the light source more in one direction than the other, and when used with collimated LEDs, provide key advantages to lighting designers and engineers. Because elliptical diffusion angles diffuse more light towards one axis,this precise control of the beam angle means light is delivered exactly where it's required and is not wasted.

Benefits of Extreme…
