Section & Light Position
Relate the section shape to the light-source position and the appearance your design needs.
Explore DLP drywall LED channels and architectural profiles for wall and ceiling details. Compare curved and angled sections, plan the board interface, and discuss the finish and supply scope.
Relate the section shape to the light-source position and the appearance your design needs.
Plan the profile, board interface and surrounding finish together for your wall or ceiling.
Discuss covers, end pieces, cable routes and maintenance access for the selected section.
Develop cut-length and finish requirements around your product range or project layout.
Open a DLP model to review its published reference and discuss the section your lighting detail needs.

Applications
Explore ceiling lighting details with the section, light-source position and surrounding board finish planned together. Illustrative application image; selection depends on the model and installation detail.

Start with the profile shape, then develop the light-source position and board interface around your lighting layout.
DLP-A08 is shown in the original source image as one section example. Matching components and supplied quantities are confirmed for the model you choose.
For perforated-flange sections integrated into a finished surface, compare plaster-in and mud-in LED profiles. The DLP collection here groups architectural junction sections.
Use an agreed dimensioned drawing for the opening and LED space; external section size is not usable strip clearance.
Coordinate fixing, board preparation and finishing while keeping the light-source position and any cover interface clear.
Plan access to the light source, wiring and driver before the surrounding surface is closed.
Board compatibility, fixing and finishing requirements depend on the selected section and construction.

Discuss changes to an existing section, or share a drawing or sample when your lighting detail needs a different profile.
Available options depend on the selected section and order requirements.
Explore Custom OptionsShare a DLP model or drawing, the light-source details and your intended wall or ceiling arrangement.
Agree the dimensioned section, board interface, finish and component scope; discuss a sample where needed.
Use the agreed specification, quantities and packing requirements as the reference for production and repeat orders.
MOQ, sample arrangements and production lead time follow our order policies below.
MOQ: 1,000 pcs per model and per finish. Custom sections have the same MOQ: 1,000 pcs. Samples are free; the customer pays freight. Sample quantity is set per project. Standard samples are usually ready within 7 days. Custom samples are arranged case by case, by agreement. Lead time: 20-30 days for all orders, counted from the date the prepayment is received. Tooling development takes about 7 days. Tooling time is not included in the 20-30 day lead time for custom orders.
The terms can overlap in the trade. This collection groups NIUYUAN’s DLP architectural sections, including curved, angled and stepped shapes. Select the model around the intended lighting and board detail rather than assuming the category name establishes a particular installation method.
No. A curve in the cross-section does not establish that a straight extrusion can bend along its length. Share your intended run layout and required radius, if any, so the manufacturing and assembly requirements can be assessed separately.
Use them as published model references when starting the discussion. The dimensions are in mm; the source insets do not identify all fitting allowances. Obtain the agreed dimensioned drawing before preparing openings, selecting a light source or confirming the installation.
Share your LED strip, connector dimensions and the light direction your design needs. The outer profile size does not define usable strip space or the finished beam angle. The light source, any cover and the section geometry are reviewed together.
These depend on the model and construction detail. Share the board type, thickness and proposed junction so the opening, support and finishing process can be agreed. A product image alone is not an approved installation detail.
The quotation defines the component references and quantities supplied for the selected model. Do not assume every DLP section uses the same cover, end piece or fixing part; the complete assembly and supply scope are agreed for your order.
Yes. Share the DLP model or your own reference, lengths, finish, quantity and installation detail. Changes to an existing section and development of a new section are considered separately. Samples, tooling, order details are reviewed for the proposed specification.
Share a DLP model, drawing or reference with your light-source details, estimated quantity and destination. Tell us about the wall or ceiling junction your profile needs to serve.
LED strips, power supplies and controllers are not included unless stated in your quotation.
