ARCHITECTURAL LINEAR LIGHTING
LED Aluminum Profiles for Integrated Architectural Lighting
A coordinated range of trimless, recessed, surface-mounted and integrated LED profiles for ceilings, walls, coves, corners and architectural details. Designed to create clean continuous light while integrating the luminaire into the architecture.
ARCHITECTURAL PROFILE SYSTEM
Build the Light into the Architecture
Architectural linear lighting begins with the way the profile is integrated into the building. Different geometries support trimless ceiling lines, recessed lighting, surface mounting, indirect coves, corners and low-level architectural details.
The aluminum profile, LED light source, diffuser, mounting method and power system can be coordinated as one linear lighting solution around the project.
Integrated Installation
Profiles can be recessed, plastered-in, surface-mounted or built into ceilings, walls and architectural details.
Controlled Light Effect
Different profile geometries support direct light, indirect light, wall washing, corner illumination and low-level lighting.
Continuous Linear Light
Profile depth, diffuser and LED strip selection work together to create clean, continuous lines of light with controlled source visibility.
Project Configuration
Profile geometry, LED strip compatibility, diffuser, mounting accessories, driver and control can be coordinated according to the installation conditions.
INTEGRATED ARCHITECTURAL PROFILES
Linear Lighting Designed into the Ceiling and Walls
Four integrated profile systems address the architectural details where linear light becomes part of the ceiling, wall, cove, corner or skirting rather than a visible add-on.

01
Trimless Ceiling
Plaster-in profiles for clean, trimless lines of light across ceilings and walls with the aluminum structure concealed after finishing.

02
Cove & Indirect
Concealed profile geometries for coves, ceiling transitions and soft indirect illumination with the light source hidden from normal view.

03
Corner
Integrated corner profiles for continuous linear lighting across architectural transitions and angled wall details.

04
Skirting & Low-level
Low-level linear profiles integrated into skirting and wall details for corridors, circulation areas and subtle architectural guidance.
STANDARD LINEAR PROFILES
Flexible Linear Lighting for Different Mounting Conditions
Standard aluminum profiles extend the linear lighting platform beyond plaster-in architectural details. Recessed, surface-mounted and suspended formats allow the same continuous-light language to adapt to different ceiling, wall and joinery conditions.

INSTALLATION OPTIONS
Recessed Linear
Flanged profile formats integrate into prepared openings while keeping the diffuser aligned with the surrounding surface. Representative profile: 4035A.
Surface-mounted Linear
Compact rectangular profiles mount directly onto ceilings, walls, cabinets or joinery when recessing is not required. Representative profile: 1013B.
Suspended Linear
Deeper linear housings can be suspended to create clean continuous luminaires above work areas, counters, circulation zones and open interiors. Representative profile: 4030.
LIGHTING EFFECTS
Shape the Light, Not Just the Profile
The profile geometry influences where the LED source sits, how the diffuser is presented and which direction the light is delivered. Selecting the right profile therefore starts with the required architectural light effect, not only the extrusion size.

01
Direct Linear Light
Use recessed, trimless or surface profiles to create clean continuous lines of direct light across ceilings, walls, joinery and architectural details.
02
Indirect Light
Concealed cove profiles direct light toward ceilings or adjacent surfaces, creating soft reflected illumination while keeping the source largely hidden.
03
Wall & Corner Light
Integrated wall and corner profiles place the light within architectural transitions, supporting illuminated edges, vertical surfaces and junction details.
04
Low-level Light
Skirting and wall-base profiles introduce linear light close to floor level for circulation, orientation and restrained architectural emphasis.
COMPLETE LINEAR LIGHTING SYSTEM
A Profile Is Only One Part of the Lighting System
A complete linear lighting solution combines the aluminum profile with the LED light source, diffuser, installation components and power system. These elements should be coordinated around the selected profile and the architectural installation condition rather than treated as independent parts.

COMPLETE LINEAR LIGHTING SYSTEM
Light Channel Assembly
Aluminum profile + compatible LED strip + diffuser form the core light channel. LED PCB width and source configuration must be matched to the selected extrusion.
Installation Components
End caps, mounting clips, plaster-in wings or other fixing accessories are selected according to the actual profile geometry and installation method.
Power & Control
Driver voltage, power capacity and dimming or control method are coordinated with the LED source and project requirements before the final system is confirmed.
PROJECT CONFIGURATION
Configure the Linear Lighting Around the Project
Select the profile around the architectural detail first, then coordinate the LED source, diffuser, installation method, length, finish and power or control requirements. Straight and bendable profile options can be considered according to the layout and the selected product geometry.

Profile Geometry — Width, Depth & Internal Channel
Installation — Trimless, Recessed, Surface or Suspended
LED Strip Compatibility — PCB Width, Power & Output
Diffuser — Match to the Selected Profile
Light Effect — Direct, Indirect, Corner or Low-level
Length & Layout — Straight, Corner, Continuous or Curved
Finish — According to the Selected Profile
