40mm Polycarbonate LED Diffuser Profile - Buyer Overview
This 40mm polycarbonate LED diffuser profile is built for linear lighting assemblies where the buyer needs diffusion, light-source concealment, PC material toughness and a clearer weathering-performance discussion in one component.
The 4mm height and 40mm width give fixture engineers a defined cross-section for LED channel matching, while the 1.3mm wall thickness helps balance profile weight, cover stiffness and light diffusion. For purchasing teams, the key value is simpler qualification: one existing polycarbonate LED diffuser profile can be checked against housing drawings, LED board position and target light output before ordering a custom run.
The LS-141 weathering masterbatch support makes this page stronger than a generic PC diffuser profile page. It gives sourcing managers a concrete formulation point to discuss when the lighting project involves UV exposure, aging resistance, yellowing control or long-term appearance stability.
The profile is especially useful when a clear protective cover is not enough. Its diffusion behavior helps soften the LED point source, reduce visible glare and improve finished luminaire appearance without moving to a separate secondary optical part.

Wholesale 40mm Polycarbonate LED Diffuser Profile - Key Advantages
Diffused Output With Source Concealment
The profile is designed for high light transmission and diffusion while improving concealment of the light source. With transmission above 80%, buyers can target a softer visual effect without removing too much usable light from the LED system.
LS-141 Weathering Masterbatch Support
The original product information highlights LS-141 weathering masterbatch developed for PC materials after research and comparative verification with customers. For project buyers, this creates a clearer anti-aging, UV-resistance and weathering-performance discussion point than a generic "weather resistant PC" claim.
PC Body for Demanding Lighting Assemblies
Polycarbonate gives this LED diffuser profile impact resistance, heat resistance and dimensional stability for lighting assemblies. For fixture makers, that means fewer concerns around cracking, deformation or handling damage during assembly.
Known Size for Faster Quotation
The 40mm width, 4mm height, 1.3mm thickness and 130g/meter weight create a clear costing baseline. Your sourcing team can compare existing tooling, freight weight and target order volume before requesting a final project quotation.
PC LED Diffuser Profile with LS-141 Weathering Masterbatch Support
This PC LED diffuser profile is supported by Dachang's LS-141 weathering masterbatch development for polycarbonate materials, making it more relevant for lighting projects where UV resistance, weathering performance and long-term appearance stability matter.
The original product page does more than list generic PC advantages. It states that the factory researched PC anti-aging performance, carried out comparative verification tests with customers and developed LS-141 weathering masterbatch for PC materials. For procurement teams, this gives the profile a stronger material story than a standard PC diffuser extrusion.
For lighting cover applications, weathering performance affects more than surface appearance. Yellowing, brittleness or dimensional change can reduce light output, affect diffuser consistency and create replacement risk after installation. LS-141 gives sourcing managers a concrete technical point to discuss during RFQ instead of relying only on broad claims such as "weather resistant PC."
The profile still keeps the core optical requirements of the product: over 80% light transmission, high diffusion, glare reduction and better LED source concealment. The LS-141 formulation capability should be confirmed during quotation when your project requires outdoor use, UV exposure resistance or longer aging-performance expectations.
LS-141 should be treated as a PC weathering masterbatch / formulation capability, not as the product name itself. If your lighting project has UV, outdoor, anti-yellowing or anti-aging requirements, list those requirements clearly in the RFQ so the suitable PC formulation can be confirmed before sampling.
Project-Ready Polycarbonate LED Diffuser Profile for Linear Lighting Projects
Project buyers can use this polycarbonate LED diffuser profile for LED lighting equipment where diffusion, impact resistance, weathering discussion and stable cover geometry are part of the fixture specification.
- Linear LED fixtures requiring a 40mm diffuser profile.
- LED channel assemblies where the light source needs better visual concealment.
- Lighting equipment that needs PC impact resistance instead of brittle cover materials.
- Projects where UV resistance, weathering performance or anti-aging requirements must be discussed before sampling.
- Indoor or protected lighting projects where glare reduction and consistent profile size affect user experience.
Custom 40mm Polycarbonate LED Diffuser Profile - OEM Manufacturing for Project Buyers
Send the drawing, sample or target cross-section when the catalog 40mm polycarbonate LED diffuser profile needs to be modified for your lighting housing, material requirement or optical target.
Drawing Review
Material Check
Die Assessment
Sample Run
Bulk Production
For OEM lighting buyers, the most important custom details are width, height, wall thickness, LED-to-cover distance, surface finish, target light transmission and weathering-performance expectation. Confirming these details before tooling helps reduce sample revisions and prevents a profile that looks acceptable alone but fails after installation in the actual luminaire.
If an existing die can be reused, the quotation process is faster. If a new cross-section is required, the project will be reviewed for die feasibility, profile cooling stability, PC material suitability and production consistency before the sample plan is confirmed.
Factory-Tested Polycarbonate LED Diffuser Profile - Quality Verification
Quality control for this polycarbonate LED diffuser profile should focus on dimensions, surface condition, fit with the lighting housing, optical output after assembly and LS-141-related material requirements when weathering performance matters.
Dimensional Check
Width, height, wall thickness and linear weight should be checked against the approved sample so the profile continues to fit the LED fixture housing during repeat orders.
Optical Check
The buyer should confirm light transmission, diffusion appearance and LED-dot concealment using the actual LED board or fixture structure, not only a loose profile sample.
Material & Weathering Check
PC material selection should match the required heat, weather and impact expectations of the lighting project. If LS-141 weathering support is required for the order, state the UV exposure, aging-performance and certificate expectations before quotation.
Bulk-Order Polycarbonate LED Diffuser Profile - Packaging & Shipping
Bulk-order packaging for polycarbonate LED diffuser profiles should protect the optical surface and maintain profile straightness during export handling.
For quotation, provide required profile length, carton requirements, labeling rules, target order quantity and whether the profiles will be assembled immediately or stored by your factory. These details affect cutting, packing density and shipping protection.
Because the product weight is 130g/meter, buyers can estimate freight impact more accurately once the final cut length and quantity are confirmed.
40mm Polycarbonate LED Diffuser Profile - MOQ & Lead Times
MOQ and lead time for this 40mm polycarbonate LED diffuser profile depend on whether the order uses an existing profile, requires new custom tooling or needs a confirmed LS-141-related PC formulation.
| Existing Profile Order | Quotation is based on confirmed quantity, cut length, packing requirement, material requirement and current production schedule. |
|---|---|
| Custom Profile Order | Quotation is confirmed after drawing review, die feasibility check and material requirement confirmation. |
| Weathering Requirement | If UV resistance, outdoor use, anti-yellowing or anti-aging performance is required, include this in the RFQ so LS-141 weathering masterbatch support for PC materials can be discussed before sampling. |
| Sample Requirement | Provide fixture drawing, LED board position and target optical effect so the sample can be evaluated under real installation conditions. |
| Certificate Requirement | State RoHS, REACH, UL, CE or project-specific documentation needs before ordering so available documents can be checked. |
