About Light Diffuser sheet/film

UVTPC-DI Light Diffuser is made of polycarbonate plastic, the thickness is from 0.06mm to 5mm, and the light transmittance is from 40% to 85%, the surfaces can be smooth, matt, frosted, etc. It is also known as “LED Light Diffuser“, “Polycarbonate Diffuser“ and “Diffuser Film”. It can diffuse luminance coming from the light source, make energy efficiency higher, and make beautiful screens without luminance unevenness.

Light Diffuser panels are mainly used in the automobile industry, for example, Car Monitors, head-up displays (HUD), and some covers of LED light. It is also used as the covers of downlights, panel lights, advertisement billboards, the light covers of the printed circuit board, office lamps, kitchen lights, and fluorescent lights.

UVTECO is a leading supplier of Light Diffuser panels/films in China, which are made of Polycarbonate plastic, and thicknesses from 0.06mm to 5mm. Meantime, we provide machining services, including cutting, printing, routing, thermal forming, etc.

Frequently Asked Questions about LED light diffuser

We have sample package of polycarbonate light diffuser with different models and different thickness, the size is 210*297mm. If you need it, please send email to info@uvteco.com.

UVTECO advises choosing polycarbonate light diffusers when they are required to be impact resistance, flame retardance and high temperature resistance.

Polycarbonate light diffusers are about 250 times harder than glass and about 25 times harder than acrylic. They are also highly resistant to temperature ranging from -50℃ to 120℃. UVTECO can provide custom-sized polycarbonate light diffusers according to your requirements.

Typical light diffuser sheet/film applications include OLED displays, area diffusers for LED lighting, backlit displays, Automotive HUDs, Mini LED, Automotive Interiors, signage, light fixtures, photography, and many others.

Yes. If you have any requirements in outdoor use. UVTECO will perform UV coating on light diffusers’ surface. It makes them be able to withstand most harmful UV rays and makes them long life in outdoor use.

It depends on your requirements.

Polycarbonate light diffuser sheet is stronger than Acrylic and work well at a higher temperature. Meantime, polycarbonate light diffuser offers higher impact resistance and can be flame retardant.

However, polycarbonate diffuser is 20% more expensive than Acrylic lighter diffuser. The final decision is made on practical applications.

There are many benefits when using polycarbonate light diffuser sheets. For example, they have high security and stability. Polycarbonate lighter diffuser sheets offer great impact resistance and can be flame retardant. Also, UVTECO polycarbonate light diffuser sheets have a long lasting service life.

Yes. UVTECO can machine LED light diffusers according to drawings from global clients.

The main differences are:

  • Impact resistance: Polycarbonate is about 25 times stronger than acrylic.
  • The hardness of the surface: Acrylic offers better surface hardness than polycarbonate.
  • Transmittance of light: Acrylic has a bit higher transmittance of light than polycarbonate.

These differences make them useful and irreplaceable in specific applications, such as automobile industry.
