Overview
PC Diffusing Sheet is a diffuser made of polycarbonate (PC) material. It is designed specifically for LED light sources to evenly disperse light, reduce glare, and enhance lighting effects. It is mainly used in LED backlight modules, advertising lighting, LCD displays and other fields.
Product Features
High haze improves light uniformity.
PC Diffusing Sheet utilizes a high-diffusing material formula and is manufactured through a sophisticated co-extrusion process, achieving a haze of over 98%. This disperses point light sources and improves lighting uniformity, making it suitable for direct-lit LED luminaires.
High transmittance ensures brightness output.
While maintaining haze, transmittance remains above 75%. By adjusting the particle distribution and particle size ratio, a balance between diffusion and light transmission is achieved, meeting the requirements of backlight unit applications with high brightness requirements.
Dimensional stability is suitable for thin structures.
PC material has extremely low water absorption, and the uniform temperature extrusion process controls thermal expansion and contraction, ensuring the sheet remains stable in high humidity or high temperature conditions. This makes it suitable for compact LED luminaire designs with tight tolerances.
Typical Applications:
LED tubular lamps, LED planar lamps, LED hospital lamps, LED billboard lamps, super thin billboards, etc.
Specifications:
Standard thickness：1.5mm, 2.0mm
Standard specification：1830x1220mm
Our company also provides cut-into-size services upon your request with our advanced CNC and cutting machinery.
Company Advantages
Mature Co-extrusion Lines
The company utilizes five high-precision co-extrusion lines to balance haze and transmittance, achieving long-term, stable mass production of high-haze PC diffuser sheets, ensuring consistent and reliable delivery for large orders.
Automated Cutting System
Equipped with CNC and high-speed cutting equipment, it supports sizing and edge processing according to customer drawings, eliminating the need for outsourcing and improving delivery speed and processing accuracy for non-standard orders.
Full-Process Control
The production process is carried out in a constant temperature and dust-free environment. Integrating an online inspection system to control thickness, haze, and optical performance deviations, we ensure consistent quality and traceable parameters for each batch of PC diffuser sheets.
FAQ
Q: What are the standard thicknesses of PC Diffusing Sheet?
A: We offer 1.5mm and 2.0mm thicknesses, and custom thicknesses are available upon request.
Q: Can it be used for outdoor lighting?
A: It is recommended for indoor use or in locations with protective structures, where it should be protected from long-term direct UV exposure.
