I-DIF is a diffusive film that uses either one or two layers of coating on a polyester base to distribute the light. The task of the film is to produce even brightness on the surface, and to redirect as much light as possible towards the target. The films are highly efficient with a lighting transmittance up 99% – depending on the film type.  

I-DIF Diffusion films is mainly used in power efficient LED lighting systems, where good illumination angels paired with high light transmission are key features. These films is suitable for both edge-lit as well as for direct-lit systems.  

The thin and flexible material enables creative design and allows efficient production methods.  

I-DIF is available in three two versions:   I-DIF 20 and I-DIF 35

The Led hiding ratio is the relation between the pitch of the LED´s (distance between the LED´s) and the distance form LED to Diffusor film.  

Grade              I-DIF20 – I-DIF35

Hiding Ratio       1:7 1:3           1:2

All I-DIF products can be tested individually or in combination with a complimenting component in our very own Light Distribution Laboratory; Ingemann Research Center. This can be done to give you the very best output-ratio, for your specific demands.
