Building Facade
Lighting Solutions

TPK delivers facade lighting as engineered solutions — matching fixture
geometry, structural limits and control planning to the real
building condition. Two paths are documented with figures from live installations.

Facade solutions we deliver

Parametric cladding and glass curtain walls impose different constraints on fixtures, mounting and control. Two paths below are documented with live project data.

Other facade conditions

Metal panel, stone & concrete, and facade renovation can be assessed against drawings and mounting constraints. A full chapter will be published when a complete project evidence pack is ready.

Discuss your facade

Pixel-Integrated Curtain Wall

The luminaire is built into the facade package, not added to its surface. Each structural node becomes one addressable pixel — so the fixture shape is driven by the architecture, and a catalogue product usually cannot be used without custom development.

When this solution fits
01

Repeating nodes

Geometric pattern with a consistent structural node at each unit.

02

Day-invisible

Fixture reads as cladding, not as a light fitting.

03

Pixel control

Individually addressed for animation, not uniform wash.

04

Weight limit

Hard limit per node. No welding to primary structure.

Challenge 01 · The shape is fixed by the building

A catalogue fixture cannot match the node

The Haitang facade uses a six-pointed star derived from the crabapple flower (海棠花). Each star is a structural element in the aluminium curtain wall. No existing model fit the shape and scale.

Resolved — LPM-MJ-HEX130-DMX from the architect's concept sketch: star aluminium body, PC face, plug-in clip into the node recess. Concept → samples → weight, thermal and aging validation → mould lock.

Glass Curtain Wall — Slab-Edge Linear

A continuous glowing line at each floor slab edge, fixture recessed into the spandrel cavity. From street level only the light is visible — every decision starts from cavity depth.

When this solution fits
01

Spandrel line

Visible horizontal spandrel; continuous line at each slab edge.

02

Built-in cavity

Access after install means removing glass, not routine open access.

03

Fixed cable entries

New penetrations need installer and waterproofing coordination.

04

US listing

U.S. projects may require a recognized NRTL listing; CE marking does not substitute for the applicable U.S. certification requirement.

A 1.25-inch cavity sets the entire spec

Spandrel cavity 1.25 inches (≈32mm) — architect submittal (BLTa): fit within 1.25" cavity. Body, clip and cable termination must clear without structural change.

Resolved — LLS-OP-W30C 30×30mm extrusion; flat clip and drainage within tolerance. Tempered glass lens over PC for multi-year UV.

Common Questions

Two documented paths: pixel-integrated curtain wall (Tianjin Haitang, 4,495 fixtures) and slab-edge linear (Live! Maryland, 860 fixtures). Other conditions can be reviewed project by project.
Yes. On Tianjin Haitang Building, TPK developed LPM-MJ-HEX130-DMX from concept sketch through samples, weight and thermal validation to mould lock.
