These lights not only enhance the safety and security of your property but also add a dramatic flair, highlighting the unique features of your landscape. Whether it's casting fascinating shadows through trees or adding visual height to walls and architecture, outdoor spot lights and flood lights transform your outdoor space. With their powerful beams and adjustable features, these lights are perfect for creating a desired ambiance, from subtle to striking.

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.

Automotive lighting engineers incorporate our diffusers into taillights and running lights to homogenize the output of LEDs as well as control the beam angle. If you've seen a recent model Dodge Durango while driving at night, you've seen our diffusers in action. Luminit light bending diffusion films are also used in automotive interior lighting, cluster panels, LCD displays, welcome mat lighting and more.

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.

Style: Choose a style that complements your home's architecture. From modern and contemporary to traditional designs, there's a wide range of styles to suit your preference.

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.

Installation Requirements: Assess the installation process, including the placement and wiring needs. Some lights may require professional installation, especially for high-powered models.

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.

Yes, we are able to increase the transmission by adding AR coating to both sides of our diffuser having the percentages 95~98 depending on the beam angle.  Our microstructures are refractive, so the performance will be constant up to ~1200nm.

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.

Thin-film Light Shaping Diffusers® are available in rolls, sheets or parts cut to your specifications. Standard rolls are 20” wide and 500’ long.

Outdoor flood and spotlights come in a wide selection of fun and functional designs, styles, shapes, sizes and uses. Flood lights illuminate a large area, while spotlights focus light on a specific feature or area of need. Both types are weather-resistant and improve nighttime safety, visibility and enjoyment. High-tech options include Bluetooth and Wi-Fi compatibility, remote controls, dimmable devices and energy-efficient LEDs. Outdoor flood and spotlights include weather-resistant floor and reading lamps and water-proof, floating pool lamps, while others even can serve as flower planters.

Our display Brightness Film (DBF) is a light management film that increases the brightness of LCD displays. DBF is a prismatic structure with either a 1, 2, 3.5, 10 or 20-degree diffuser on the other side of the film. DBF is also available without the diffuser.

Outdoor flood and spot lights can be strategically positioned to maximize both functionality and aesthetic appeal in your outdoor space. Flood lights are ideal for areas requiring broad illumination. They are commonly placed in high-traffic outdoor areas such as driveways, backyards, and parking lots, or used to enhance the security around building perimeters. These lights are typically mounted at higher points, like the corners of buildings or under soffits, to cover a larger area. Their wide beam spread ensures that these spaces are well-lit, promoting safety and visibility. Flood lights are also effective in lighting up outdoor socializing spaces, like patios and pool areas, providing a welcoming and secure environment for evening activities.

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

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

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.

Spot lights, on the other hand, are used for more focused lighting needs. They are perfect for accentuating specific features of your landscape, such as the intricate textures of stonework, the majestic presence of large trees, or the artistic details of sculptures and architectural elements. They can also be used along pathways or in garden beds to create dramatic effects, guiding the way and adding a touch of elegance. The combination of flood and spot lights in an outdoor space allows for a comprehensive lighting scheme, where general illumination is complemented by focused attention on special features, creating a dynamic and inviting outdoor environment.

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.

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.

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.

Durability: Look for lights that are built to withstand outdoor conditions. Ensure they are weather-resistant and suitable for the climate in your area.

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.

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.

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.

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.

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.

Luminit's unique LED optical diffuser material is available in a variety of circular and elliptical angles from 1° to 100° on thin film or rigid substrates. Standard angles include: 80ºx50º, 60ºx10º, 80º, 60º, 40º, 30°, 20°, 10°, and 5°. We also offer non-standard angles, including 1°, 2°, 3.5°, 30°×35° 40°×1°, 60°×1°, 69°×30°, 75°×45°, and 90°×10°.

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.

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

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.

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.

The EVD unit has an 81% transmission efficiency in the “on” state and 78% in the “off” state measured at 550 nm at 28°C. Anti-reflection coated glass laminates are available on a special order basis to improve transmission.

Energy Efficiency: Consider LED options for their lower energy consumption and longer lifespan. LED lights are not only cost-effective but also offer superior performance.

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).

Yes, you can layer multiple sheets of DTF to increase the angle of redirection; however, there will be significant transmission loss.

We recommend you find a mechanical means of securing the diffuser into your system, for example using the natural tension of a film on curved surface. We offer pressure-sensitive adhesive (PSA) as an option but this process is difficult and you may experience the incorporation of air bubbles during the lamination process.

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.

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.

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.

Purpose: Determine whether you need broad illumination (flood lights) or focused lighting (spot lights). Flood lights are ideal for lighting up large areas like driveways and backyards, while spot lights are perfect for accentuating specific features like garden elements or architectural details.

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.

Though our LED diffuser sheets are often installed in outdoor environments, they are not waterproof. Submerging the diffuser film or sheet in water would dissolve the microstructures and render the diffuser unusable.

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

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.
