Flexible luminaires for tracks to produce accent lighting

Spotlights illuminate a narrowly constrained area. The mounting location and the orientation are variable. Spotlights are offered with different beam emission angles and light distributions.

Criteria for spotlights
- choice of luminaire determines lightcolour and light intensity
- emission angle determines the beam of light and is defined by the interchangeable lens
- cut-off angle limits glare and increases visual comfort
- rotatable and tiltable
- snoot as accessory for improved visual comfort


Spotlights have a narrow-beam (spot from approx. 6°) to wide-beam (flood approx. 45°) light distribution with a rotationally symmetrical beam. Spotlights are also available with axially symmetrical light distributions or with asymmetrical light distributions. In luminaires with Spherolit lens, the lenses are usually interchangeable, thereby also changing the characteristics.

Spotlights can generally be rotated and tilted; the oval flood lens of floodlights can be adjusted for optimum alignment.

Contour spotlights with lenses for projection for various beam emission angles.
Some types of spotlight are equipped with convex lenses or Fresnel lenses for a variable beam angle.
In addition, spotlights with image contouring or projecting systems (contour spotlights) enable different beam contours or projected images by projecting through apertures or stencils (gobos).

On pictures on walls or objects in a room, the light should be incident at an angle of less than 30°.

For highlighting or projection in:
- museums
- exhibitions, art galleries
- sales rooms
- presentation and display areas

Since they enable variable mounting locations and orientation, spotlights can be adapted to suit changing tasks.
A narrow light distribution enables smaller areas to be illuminated, even from a larger distance. Conversely, the wide light distribution of projector floodlights enables a larger area to be illuminated with a single luminaire.
Gobos and structured lenses are used to project lighting effects.
In addition, filter foils can also be used.
