What is a Polycarbonate Extrusion Diffuser Lampshade?

A Polycarbonate Extrusion Diffuser Lampshade is a precision-engineered optical lighting component made from high-performance PC (polycarbonate) material. It is designed to diffuse LED light evenly, reduce glare, and improve lighting comfort while maintaining high light transmission efficiency. 
Compared with standard plastic covers, PC diffuser lampshades offer superior impact resistance, heat resistance, and long-term optical stability, making them ideal for modern LED lighting systems.

Core Features and Advantages

Material Advantages – Why Polycarbonate (PC)?

Manufactured using co-extrusion technology; made of acrylic and aluminium; features the thickest diffuser design.
Polycarbonate is widely used in professional lighting due to its balance of optical clarity and mechanical strength.
Compared with acrylic:
PC is more impact-resistant (not easy to break)
Better heat resistance for LED applications
Longer lifespan in outdoor or industrial environments
More stable under continuous lighting conditions

Performance:

The light transmittance of the LED Polycarbonate Extrusion Diffuser Lampshade is as high as 80%, making it less prone to light spots. The light is uniform and soft, and it has anti glare function; Durable, shatterproof, UV resistant, not easily yellowed under long-term sunlight, with a longer service life; Environmentally friendly and compliant with ROHS standards, achieving global safe exports.

FAQ

Q1: What is a Polycarbonate Extrusion Diffuser Lampshade used for?
It is used to evenly diffuse LED light, reduce glare, and improve lighting comfort in residential, commercial, and industrial applications.

Q2: What is the difference between polycarbonate and acrylic diffuser lampshades?
Polycarbonate is more impact-resistant and heat-resistant, while acrylic offers higher clarity but is more fragile. PC is preferred for industrial and long-term applications.

Q3: Does a PC diffuser reduce brightness?
It does not significantly reduce brightness but redistributes light to make it more uniform and comfortable for the eyes.

Q4: Can Polycarbonate Extrusion Diffuser Lampshades be used outdoors?
Yes, high-quality UV-stabilized PC diffuser covers are suitable for outdoor lighting systems.

Q5: What are the customization options available?
Typical OEM options include length, thickness, diffusion level, surface texture (frosted, prism), and shape design.

Q6: How long does a PC diffuser lampshade last?
Under normal conditions, it can last 5–10 years depending on UV exposure and environmental conditions.

Q7: Is PC material safe for lighting applications?
Yes, polycarbonate is widely used in lighting due to its flame resistance, durability, and optical stability.

Q8: What is your delivery time?
It takes about 7 to 15 days to make a new mold/tool. Mass production takes approximately 30 days.
