For planar illumination, recessed floor luminaires or projectors with wallwash or flood lenses are suitable.

An option is to use wallwashers to provide uniform lighting over the entire area.

Advantageously, the lighting source generates flat lighting.

The illumination units can furthermore in particular generate a planar and homogeneous illumination of the objects.

Particularly, a planar lightning may be realized by multiple LEDs.

For wide-area lighting, a wallwasher module fitted with T16 fluorescent lamps is available.

This high-tech startup has developed planar lighting that can be used to display a wide range of light scenarios.

The optical axis (6) for the surface illumination is, in this embodiment, in the bisecting line of the angle of the other two optical axes (5 and 7).

If the diffuser is introduced into the beam path, the light is scattered in a wide variety of directions, such that an areal illumination is produced.

The light source 14 is designed as a projection unit 40 allowing an areal illumination of the display screen 12 .

Also, point light sources with an aperture angle or radiating light cone are usable for planar illumination, in which case the shadow image is projected in a magnified manner compared to the actual size of the specimen depending on how close the point light source is to the specimen, since this is a central projection.

For the purposes of recording the fingerprint, an illumination unit should ensure an areally homogeneous illumination and should preferably also be quickly switchable.

Such devices are used in lighting systems in order to achieve a colored or planar illumination of spaces, paths or escape routes.

Instead, a planar illumination may be desired here, through which it is ensured that the whole two-dimensional code area is illuminated.

The inventor realized that LEDs can be densely packed on an areal arrangement in such a way that they represent an optimum areal illumination with emission in one direction.

Thus, in relation to a vertical plane oriented normally to the longitudinal axis L, the second switching state enables a symmetric light emission of the luminaire, in particular in the form of a batwing distribution, which is therefore particularly suitable for a general illumination or a “planar” illumination.

However, light sources are generally in point or line form, such that the light has to be distributed over the surface for areal illumination.

Also the laser beam may be widened for illumination possibly by means of a beam splitter with a suitable optic, in order to generate areal illumination in addition to the line projection.

The film as a lighting source advantageously generates uniformly flat illumination (light sheet) of an area of the pane, when it is driven electrically in an appropriate manner.

This was followed immediately thereafter by full-area illumination by means of a CF2000 UV-LED system from Clearstone Technologies at a wavelength of 365 nm, at a power density at the surface of the film of 40 mW/cm 2 for 300 seconds and an accumulated dose of 12 J/cm 2 .

The lighting source generates uniformly flat illumination (light sheet) of an area of the pane, together with the diffusion element.

At the same time, the polymer permits illumination of the background over a surface area, it also being possible for the pointer instrument to be integrated into the indicating instrument in such a way that it is highlighted against the background, and consequently readable, only when the illumination is switched on.

However, because in this case a planar projection of the object is needed by the camera, or a planar illumination of the object is needed by the stroboscopic lamp, the beam splitter must be arranged in the beam path between the object to be measured and the spatial filter.

The highly efficient system consisting of collimating and interchangeable Spherolit lenses provides the designer with a wide variety of light distributions - be it for precise accent lighting using narrow spot, the washlighting of horizontal product displays with oval flood or the uniform illumination of shelves using wallwashing.

This is possible following the deformation of a random pattern at the sample surface and evaluation (Digital Image Correlation, DIC) or by recording the crack contour by homogeneous illumination of the sample from the bottom side (Digital Image Elaboration (DIE)).

An illumination unit for planar illumination is already known from the related art.

This represents a more cost-efficient alternative compared to planar lighting across complete storeys

In addition to such surface illumination, square luminaires can also produce accentuated light.

Hereby the surface illumination of the light-emitting panel can be generally done in various ways.

Good quality of illumination is achieved primarily through the combination of planar and point sources.

The closer the individual LED dots are to each other on a strip, the more flat the lighting appears.

The creative scope here ranges from uniform illumination of large areas for a grand gesture through to grazing light to emphasise the surface texture of walls.
