Polycarbonate Diffuser-PC

Led Diffuser Sheets
Product Description

In general, a light diffuser is any material placed in the path of a light source that causes light to spread. LED luminaire manufacturers often rely on light diffusers to soften shadows and eliminate glare. While the advent of LEDs has brought about excellent energy efficiency and superior light controls, the point sources present in the LED chip boards pose a challenge for general illuminations in the form of glare. So, the LED light fixtures use specially designed covers that are optimized to offer light diffusion properties. Additionally, these covers serve the purpose of shielding the light source as well. While most LED light diffusers serve the same purpose, they differ in the key materials that they are made of. And, this is where their quality comes into the picture.

Product Properties

Advantage Disadvantage

Advantage Disadvantage
It has a high impact strength. It has a relatively low light transmittance relative to PMMA light diffusers.
It has a high heat distortion temperature. It is an expensive material relative to PS but priced similar to PMMA.
It is resistant to weathering.  

In conclusion, when it comes to durability and stability, PC diffusers are one of the best polymers to rely on, given its high fire-rating and good safety certifications.
