Light diffuser films

Clever materials for luminaires, digital signage and backlit displays

Streuscheiben

A diffusing lens or diffuser is used to break up and distribute light evenly. Light rays incident in parallel are distributed in different directions and thus produce diffuse, glare-free light. Diffuse reflection and refraction of light are the optical effects used for this purpose. They are achieved by a rough surface and / or embedded colour pigments or diffuser particles.
One classic area of application is the use of diffuser films in the backlight unit (BLU) of LCD displays. Newer fields of application are

Streuscheiben LED-KorridorDiffusion for:

  • Direct or indirect lighting
  • trade fair construction, digital signage, design objects
  • Backlight
  • lamps, light boxes
  • Warning lights, orientation lights
  • Displays in car interiors, speedometers
  • HiFi control elements

Diffuser films or sheets ensure uniform brightness, both in conjunction with conventional light sources and with LEDs. They can prevent or at least significantly reduce unpleasant HotSpots with point or linear light sources.

TTV offers diffuser films and sheets

  • in several variations
  • acrylic- or polycabonate-based

that

  • meet highest requirements in terms of light diffusion
  • enable flat design and construction
  • are colourfast and weather resistant (PMMA)

Our diffuser foils differ by their

  • diffusing effect (half-value angle)
  • transmission
  • Thickness (0.2 bis 5.0 mm)
  • Stability / Bendability
  • Colour (shades from crystal-clear to opaque / white)

Frequently asked questions:

  • 1.

    Which material is suitable for backlighting LED / LCD displays?

    We have suitable films and sheetss for light diffusion for direct, vertical light as well as for lateral edge lighting. Please contact us!

  • 2.

    Hotspots are visible despite the diffusing lens. What can you do?

    Whether or not diffusers actually produce homogeneous illumination with punctual light input (by LEDs) depends individually on the type of diffusing filter used, the light source used and the distance between diffuser and light source. We will be happy to send you various material samples for testing on your specific application and installation situation.
