Low-UGR Serrated Shape LED Strip Opal Diffuser for Softer, Even Light
On the Serrated Shape LED Strip Opal Diffuser the serration does real work; it is not a decorative texture. Dachang runs a row of fine sawtooth facets along the under-surface so that the sharp, bright line of the LED strip is broken into many gentle reflections before the light ever reaches the opal face and the eye.
That is exactly the effect a lighting designer is chasing. The diode array disappears behind the opal, the fixture reads as a single continuous band of light, and the intense peak brightness that makes people squint is calmed right at the surface rather than thrown away as lost output. Because the sawtooth geometry and the opal polycarbonate diffuse the light together, this one extruded cover often does the job that many fixtures need two parts for - a milky sheet plus a separate prismatic or louver optic - and it sidesteps the visible hot-spots those stacked layers tend to leave along a run.
At a 1.5 mm wall in optical-grade PC, the profile stays light enough for cove, under-cabinet and suspended linear work, while polycarbonate shrugs off the knocks of handling and on-site fitting. Soft, glare-controlled light; a clean hidden source; a body that lasts - that is what tells a purpose-built anti-glare diffuser apart from a plain clear LED cover.

Wholesale Serrated Shape LED Strip Opal Diffuser for Project Buyers
Most sourcing managers looking at an anti-glare diffuser are really trying to solve three things at once: pass the designer's visual sign-off, keep the bill of materials simple, and have the part actually fit the channel. This diffuser is shaped around those three.
Glare control that saves a part
The sawtooth surface flattens the diode's brightness peaks right at the opal face, so your fixture can reach its glare and UGR target without a second optical layer stacked on top.
For your BOM: one extruded opal diffuser instead of a diffuser-plus-louver stack, so fewer parts to buy, fit and troubleshoot.
Opal finish that hides the LED source
The opal polycarbonate keeps the LED strip out of sight even when the fixture is viewed from an angle, so what people see is a smooth line of light rather than a row of dots or drag marks.
For your project: the clean, uniform look that gets signed off the first time it reaches the designer.
A diffuser cross-section made for your channel
The 50 × 40 mm profile is our standard, but Dachang re-cuts the snap geometry, wall and serration to your housing, and the ±0.5 mm cut tolerance keeps a tight seam on continuous runs.
For your line: a diffuser that clips into your channel on the first sample, not the third.
Optical-Grade Polycarbonate LED Strip Opal Diffuser and Its Serration Optics
Dachang extrudes this opal diffuser from optical-grade polycarbonate rather than cast sheet, so the serration and the diffusion are formed in the same pass and repeat identically down every metre of profile. Polycarbonate brings the impact strength that public and commercial fixtures need, and it holds its shape under the warmth of a running LED strip where thinner or cheaper resins start to sag.
The sawtooth under-surface is a tuned optical feature, not a fixed pattern. Its facet angle and pitch decide how firmly the bright diode peaks are broken up against how much light is kept - a gentler cut for maximum output, a deeper one where glare control matters most. Because the opal is dispersed right through the wall rather than printed on the surface, that soft, even light will not scratch or wear away in service.
Configured with you at the tooling stage
Serration depth and pitch tuned to your balance of glare control and light output
Opal density set to how completely you need the LED source hidden
Flame-retardant PC grades available on request for regulated interiors
Custom colours and a cross-section re-cut to your own luminaire drawing
Project-Ready LED Strip Opal Diffuser for Office, Retail and Hospitality Lighting
Glare control tends to be a hard requirement in exactly the spaces where linear light is most on show. Dachang makes this serrated diffuser for the lighting brands supplying those projects, where an even, comfortable line of light is written into the brief rather than treated as a nice-to-have.
Office and commercial linear lighting
Open-plan offices and meeting rooms are designed to glare limits under standards such as EN 12464. The serrated surface helps a linear fixture hold a low-UGR result at the desk while still reading as one continuous line overhead.
Retail and display lighting
Shelf and display runs need the product well lit without the fixture glaring back at the shopper. The opal cover keeps the diodes invisible, so attention lands on the merchandise instead of the light bar.
Hospitality and architectural cove
Hotels and public interiors specify long unbroken coves where any visible dotting looks like a fault. This diffuser gives the soft, artefact-free line those fit-outs are signed off against.
Schools, clinics and transit interiors
Institutional spaces ask for a long service life alongside real visual comfort. Durable polycarbonate and built-in glare control suit fixtures that stay lit for years in occupied rooms.
Custom Serrated Shape LED Strip Opal Diffuser OEM and ODM Manufacturing
Send the section drawing of your channel or luminaire and Dachang quotes the tooling and unit price straight against it. Treat the 50 × 40 mm profile as a starting point; the snap geometry, wall, serration and finish are all re-cut to your part. New tooling takes about 15 days, production runs on a 10–15 day cycle once you have confirmed the samples, and terms are T/T with a 50% deposit that covers tooling and order together.
Because the moulds are made in our own factory, the diffuser is engineered to your fit and your glare target from the very first tool, not adapted from someone else's profile. If you are pulling together a whole range of fixtures, we can tool a family of matched cross-sections so one supplier covers your entire linear line.
Quoted against your section drawing, with no forced standard profile
In-house tooling, so the serration, snap fit and opal finish are tuned per part
A sample-then-order flow, with your confirmation before we start production
Factory-Tested LED Strip Opal Diffuser with RoHS, REACH and ISO 9001
The material and the process are documented for export from the resin up. The polycarbonate meets RoHS and REACH requirements, so the diffuser slots into your compliance file without leaving a substance question hanging. Production runs under an ISO 9001 quality management system, with dimensional and finish checks that hold the ±0.5 mm cut tolerance and keep the serration consistent along the whole run.
- RoHS material
- REACH compliant
- ISO 9001 quality system

For regulated interiors, flame-retardant PC grades can be specified at the tooling stage; Dachang confirms the exact grade and any extra test data against your project's fire code before the mould is released.
Bulk-Order LED Strip Opal Diffuser Packaging and Shipping
The diffuser ships in carton boxes, cut to your specified length so the profiles arrive ready to feed your assembly line instead of needing a second cutting step. Dachang sets the length, bundle count and carton layout to protect the opal face and the serration edge in transit, and packing can be marked to your own project or SKU references on bulk orders that feed several fixtures at once.
Serrated Shape LED Strip Opal Diffuser MOQ and Lead Times

Serrated Shape LED Strip Opal Diffuser Procurement FAQs
Q: Does the serrated diffuser guarantee a specific UGR value?
A: The serration lowers the diode's peak brightness at the surface and helps your fixture reach a low-UGR result, but the final figure depends on your LED, driver and housing working together. As a serrated LED diffuser manufacturer, Dachang tunes the facet depth and opal density to your glare target and supplies samples so you can validate the photometrics in your own fixture.
Q: Can the cross-section be customised to our own channel?
A: Yes. The 50 × 40 mm profile is only a starting point. Send your section drawing and we re-cut the snap geometry, wall thickness, serration and finish to your part. Because Dachang makes the moulds in-house, all of that stays on one timeline.
