With the recent unveiling of Facebook becoming Meta, advances in AR/VR technology seem to be on the horizon. As Meta takes the fore in the development of AR/VR technology, and other tech giants not far behind, we can expect the way we view content—not only the amount but the way that information is shown to us—will change forever.

For one thing, immersion will be the name of the game as, presumably, full dive VR is the ultimate objective. Near-to-eye (NTE) technology means the screens are less intrusive to the…

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 micro particles 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 high temperature glass diffusers…

Luminit has been granted a patent for an optic that takes a collimated light source and converts it to a wide 180 degree fan of illumination. Flat optics like our Lighting Shaping Diffusers use refraction to increase the beam angle of a collimated light source; this typically is limited to about 100 degrees. The 180 degree Illuminator, however, takes a different approach with a combination of cylindrical and conical sections. Here’s how it works. 

After a collimated light source (i.e., VCSEL, laser, LED) enters the…

Luminit’s Light Shaping Solutions are known as potent problem solvers when light designers, engineers, and OEMs need to get more out of less and increase the value of a single downlight design. For example, a can ceiling downlight may have a native beam of 20° FWHM.  When an 80° Light Shaping Diffuser is integrated into the fixture, the same downlight will flood a whole area with soft, uniform light. Likewise, the same can light with a…

Many lighting manufacturers recognize the key role tertiary optics such as Light Shaping Diffusers® play in creating more Human Centric Lighting (HCL) conditions, or lighting that considers 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.

Luminit’s considerable library of circular, elliptical, and extreme elliptical beam angles accomplish different goals for different customers.  Our elliptical angles, also called asymmetrical, are popular with lighting customers because these LED diffusers direct a light source in one direction or axis more than the other so that the light goes exactly where it’s needed. For example, add our 60° x 10° elliptical diffuser to an LED spotlight and the output goes from circular to oval. In addition to reshaping the beam, the diffuser…

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).
