What are light management films?
LED lights are transforming light and offer new and innovative design possibilities. But LED sources also cause challenges when it comes to glare, hotspots, and light uniformity.
Technical films for illuminated applications are the perfect solution for the lighting industry as well as for automotive, consumer electronics, and construction applications. With these clear and white films, you can achieve an improved light diffusion and light transmission, while at the same time saving energy. They can be used to create different lighting effects depending on the type, power and position of the light source. They also act as a protector of the light sources like LED lamps. Technical films can be formed into a variety of shapes to satisfy your application and design needs.
What types of light management films are there?
As a specialist for technical films, the König Film Centre offers you a wide range of products for LED lighting systems. These are polycarbonate films of the Makrofol® brand from the manufacturer Covestro and Lexan® from the manufacturer Sabic. In addition, there are Plexiglas® PMMA films from the manufacturer Röhm. The films are available in rolls or rectangular sheets.
We distinguish between the following three product areas:
- Light diffusion films also called diffusion films or diffuser films
- Light-directing films also called lenticular films
- Reflective films
We offer you samples of all clear, translucent and white light management films. Just contact us, we will be happy to advise you in the choice of the right film diffuser product for your application.
Light diffusion films
The translucent white diffusion films impress with their homogeneous diffusion and transmission of light. This makes them the ideal solution for a wide range of applications and processes using LED light and the lighting industry. Our diffuser films can be your solution to avoid glare and hotspots and to achieve an evenly spread light.
Translucent diffusion films are milky white films with a polished surface and special additives developed for this application. When used in backlit components, our diffuser films provide uniform and homogeneous illumination over a wide area. The light sources behind them are no longer visible. The high-performance films provide a range of levels of diffusion and transmission, high impact resistance and excellent temperature resistance for optimised LED lighting systems.
The white light diffuser films differ from each other in terms of transmittance (light transmission) and half-value angle. Depending on the application and surface, a different type of diffuser film with different light values is recommended. Some white diffuser films come with a protection film on the surface. Try our diffuser films to improve your lighting and reduce glare and hotspots.
Film for the direction and diffusion of light
This is a lenticular film used to direct the light. The optical line structure incorporated into the polycarbonate film (PC) acts as diffuser and enables light to be directed and scattered evenly. This allows different lighting effects to be created depending on the light source and illuminant. We offer high quality lenticular films of the Makrofol brand from the manufacturer Covestro.
Reflective films
The opaque polycarbonate film with a high-gloss white surface offers a high light reflection. White reflective films reflect the available light almost completely back to the observer and thus significantly increase the efficiency and luminosity of lamps. Typical applications of the translucent white reflective polycarbonate film come from the lighting technology and the lamp industry. They are the ideal solution in order to increase the amount of light.
Properties of light management films
Translucent Light management films are made of various materials. Among the most common are polycarbonate (PC) and PMMA. This also results in variables in product properties and areas of application. Films made of PMMA are more suitable than polycarbonate films for outdoor applications thanks to their high UV resistance. Other luminescent films have a very high impact strength or increased temperature resistance. For more information on the individual products, please contact us.
We offer a range of white translucent diffuser films for lighting applications cut to size or as rolls directly from our film warehouse in Wuppertal / Germany. Please contact us for special sheet sizes. Our team will be happy to advise you. In addition, we offer a sample service so that you can convince yourself of the film properties (surface, light transmission, light transmittance). You can use prototypes or test set-ups to check the suitability of the films for your application in advance. This will ensure that the selected light technology film is the right one for your application. We look forward to your enquiry.
Where are light management films used?
Typical applications of our clear and white light management films are in the advertising as well as the lighting industry. In addition, clear or translucent light management films made of polycarbonate or PMMA are also used in the following areas:
- Interior parts for the automotive industry
- Diffusion of LED light (light diffusion, light control)
- Backlit displays and switches
- Residential and commercial lighting systems
- Lamps, luminaires and lampshades
- Illuminated advertising and signage
- Use for various industrial products
Are light management films UV resistant?
All films for lighting applications have a certain UV resistance. Our PMMA films have a particularly high UV stability. For applications where the film products are exposed to long-term UV, we recommend the use of PMMA film or special polycarbonate films as solution with high UV protection.
Can light management films be further processed?
All films for LED lighting systems can be further processed with suitable accessories. The processing depends on the material of the film. Clear or translucent Diffuser films for lighting applications can all be printed without any problems.
Our service
We offer our clear and white films for light diffusion in different surfaces in thicknesses from 150 µm to 500 µm as rolls. Depending on the thickness, the roll length and colour of the light films differ. We are happy to cut the rolls into rectangular sheets in the format you require. Just tell us the format you need and we will send you an offer for our film products at an attractive price. Special shapes are also possible on request. You can buy films for lighting technology from us! Just use our contact section on our website www.folien-zentrum.com to send us an inquiry.
We deliver all stocked light diffusion and light management films within a few working days. For delivery, the product is professionally and safely packed as protection. If you have any further questions about our range, our suppliers such as Lexan and Makrofol, our cutting service, delivery and any other concerns, we will be happy to advise you. Please contact us if you need technical data sheets or samples of our lighting technology films for the construction of first prototypes.
