Polystyrene Diffuser-PS

Polystyrene Diffuser-PS

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 good optical characteristics. It has a low impact strength.
It is adequately resistant to wear and tear from surface scrubbing while cleaning PMMA is a slightly costly material in comparison to PS, which drives up the cost of the fixture.
It has good chemical and thermal stability. It has low weather resistance. Long exposure in outdoor environments makes PS diffusers
go yellow and get slightly brittle
It has high radiation resistance. Its heat resistance is poor.
It resists moisture absorption, making it ideal for humid environments.  

In conclusion, PS has many shortcomings, but for its use in the light guide plate of LED panel lights, its advantages stand out due to its low cost factor. Furthermore, it's low cost and a decent light transmission rate of 88%, (less than that of acrylic diffusers) makes it an ideal diffuser for indoor lights.
