Polycarbonate films for light diffusion

Diffusor films for an ideal light diffusion

The market for light-emitting diodes in lighting is booming. This is hardly surprising since the LED technology has huge advantages: they consume less energy than incandescent bulbs and discharge lamps and help protecting the environment, and have a much longer service life. If you are designing or manufacturing an LED lighting component for commercial, industrial or residential use, we have the solution you need. We offer a wide range of technical films for the diffusion of light and LED light. These films act as diffusor to avoid that the light source gets visible. In addition to a high light transmission, all our diffusor films show a good heat resistance.

A diffusor film is needed to spread and diffuse the light of the LED over the entire surface of the light surface. Like this no single light sources are visible, but the optical brightness is spread over the whole surface to achieve a perfect illumination.

As a specialist for technical films and thin sheets, the König Film Centre offers you numerous diffusor / light diffusing films for lighting applications and the design of high quality lights. These are polycarbonate films (plastic) of the brands:

• Makrofol ® - polycarbonate diffusor material from the manufacturer Covestro
• Lexan ® - polycarbonate diffusor material from the manufacturer Sabic

The translucent diffusor films impress with their homogeneous diffusion of light and provide an excellent light diffusion. This makes them the ideal solution for a wide range of applications in lighting technology and the lighting industry. The diffusor films are used for spreading light and dividing the brightness and glare over the whole area of the lighting surface. The diffusion can vary from translucent and strongly light-scattering films. We supply you our film diffusor as rolls or sheets. Just tell us the sheet size and we prepare you a competitive quote.

Properties of a polycarbonate light diffusor film

Translucent diffusor materials are designed for light diffusion in high quality lighting applications. These films in milky white color contain a scattering additive specially developed for this application for uniform light diffusion. When used in backlit components using LED light, our light diffusion films provide uniform and homogeneous illumination over a wide area.

The different light diffusion films differ from each other in terms of light transmission (light transmittance), the half-power angle and color. Depending on the application, the light source, we recommend you a material with suitable light values. The surface of the film has a slight glare without being reflective.

Our translucent polycarbonate films for light diffusion are particularly impressive due to their mechanical strength and impact resistance. In addition, they have a distinct temperature resistance from - 40 °C to 130 °C (continuous operating temperature of 105 °C), a high dimensional stability as well as good dielectric and insulating properties.

Applications of polycarbonate diffusion films and sheets

Typical applications of our films for diffusion of light and LED light are:

• Diffusion of LED light (different energy classes and technology)
• Design of backlit displays
• High glare and brightness for perfect illumination
• Backlit switches used for industrial application
• Design of lamps and lampshades (used with LED light or other light)
• Interior parts for use in automobiles
• Illumination for advertising
• Light boxes with small depth
• Illumination of work spaces, offices or homes
• Diffusion of light from different light sources and energy classes

Processing of light transmission films

Thanks to their surface structure with a slight glare (without being reflective), our polycarbonate light diffuser films are characterised by good and constant printability. Furthermore, our diffuser films can be cut, punched, lasered (partly possible), embossed and glued using professional accessories. Polycarbonate light diffuser films are suitable for deep drawing and back injection and the insert moulding process (FIM) as well as high pressure forming (HPF). The films we offer can be cold and hot formed. Our polycarbonate light diffusion films are also suitable for special applications such as deep drawing or high-pressure forming.

No special accessories or tools are required for processing our sheets of light diffusion films.

Our service

We provide you polycarbonate light diffusion films in thicknesses from 150 µm to 500 µm as sheets or rolls. The roll length of each diffusor film varies depending on the thickness. We are happy to cut and convert the rolls into rectangular sheets in the sheet format you require. Just tell us the required sheet size and we will send you an offer with an attractive price for sheets or rolls.

We will be happy to advise and consult you in the planning of your project and send you technical data sheets or samples of our plastic films for the construction of initial prototypes. We also offer reflective films (in bright white color) or optical clear films that can be used in combination with a diffusor film. Reflective films can be applied in the rear side to enhance the light in an lluminated surface.

We deliver all stocked materials converted into sheets or rolls within a few working days. For delivery, the plastic product is professionally and safely packed.

If you have any further questions about our range of plastic materials, suppliers such as Lexan and Makrofol, the color and light transmission of our films, our cutting service into sheets, delivery and any other concerns, we will be happy to advise you.
