Complete LED tread

A 30 mm solid-oak board with a fully removable 15 mm illuminated cassette attached below, set back from all four edges.

Construction summary

Overall tread: 900 × 280 × 30 mm

Underside cassette: 840 × 210 × 15 mm

Built-up height: 45 mm

LED per tread: 2 × 800 mm

Power at 24 V: 16 W nominal

Rev B: optical correction. The guide panel is 830 × 204 mm rather than 830 × 198 mm in the earlier PDF. This closes the excessive edge gap to the LED strips. Confirm all clearances on a prototype.

Concept geometry, not a structural drawing. Actual staircase supports, fixing positions, thermal performance and electrical protection require on-site verification. No proprietary or custom-made parts are assumed.
