LED aisle lighting in the IMAX auditorium at Traumpalast Leonberg
Case study · Traumpalast Leonberg · IMAX

Cinema aisle lighting at IMAX Traumpalast Leonberg.

Around 450 metres of SL1 illuminated stair nosing guide visitors through the dark IMAX auditorium at Traumpalast Leonberg, Germany. Integrated row indicators, mitred profile joints, DMX lighting scenes and coordinated normal and backup operation bring step and seat-row identification into one system.

The challenge

Make the steps visible while keeping the auditorium dark.

Visitors need to identify steps and seat rows even when the house lights are very low. The aisle lighting must provide those visual cues without distracting from the screen.

The challenge extended beyond the installation’s scale. Around 450 metres of light line had to follow several changes of direction, accommodate row indicators and respond to the cinema’s operating modes.

Design principle For cinema aisles, the aim is a clearly visible step edge with as little interference as possible with the dark viewing environment.

SL1 profiles follow the angled aisle steps through accurately mitred joints.
Geometry & wayfinding

Illuminated stair nosings shaped to the auditorium.

The stepped aisles change direction several times. Profiles were made to length and mitred at each change of direction to match the actual step layout.

Mitres
Continuous changes of direction Mitred profile ends follow the angled steps without abrupt visual breaks.
SL1
A defined step-edge line Light remains concentrated at the step edge for a restrained effect during screenings.
Rows
Integrated row indicators Seat-row identification and step lighting are designed together.

01 · Admission Help visitors find their seats A higher light level assists arriving visitors and seat finding.
02 · Interval A separate dimming level An independent scene sets the brightness appropriate for the interval.
03 · Screening A discreet light level Step edges remain visible while the aisle lighting recedes into the background.
Controls & operation

DMX scenes for screenings, with coordinated backup operation.

The installation supports several operating modes. Brightness is controlled centrally through DMX, with manual adjustment also available directly at the dimmers.

Power supplies and circuit allocation were coordinated for normal and backup operation in this particular installation.

Profiles, row indicators, dimming, power supplies and operating scenes were specified as one coordinated cinema aisle-lighting system.

The result

Large-scale aisle lighting that stays discreet during the film.

The completed installation combines continuous step-edge marking, integrated row indicators and scene-based dimming. The electrical and geometric requirements of a large auditorium are resolved without making the light lines dominate the space.

Geometry resolvedProject-specific mitre cuts accommodate the angled aisle steps.
Coordinated wayfindingStep lighting and row identification form a single system.
Scenes for each operating modeAdmission, interval and screening can use different brightness levels.
Good cinema aisle lighting is easy to find when you need it and unobtrusive while you watch the film.
FAQ

Questions about the IMAX Leonberg installation

Which LED step profile was installed?

The project uses approximately 450 metres of SL1 LED step profiles.

How were the angled aisle steps handled?

SL1 profiles were made to length and mitred wherever the steps change direction.

Were row indicators integrated?

Yes. The row indicators are integrated directly into the step profiles to assist seat finding.

How is the installation controlled?

Brightness is controlled centrally through DMX. Manual adjustment is also possible directly at the dimmers.

Is the system designed for backup power?

Yes. Power supplies, circuits and operating modes were coordinated for normal and backup power in this project.
