Abstract
An optical system is usable to form an illuminating strip on a surface of a material. The optical system includes an illuminating device which contains several light sources which are located at a distance from the surface of the material. The illuminating device uses its light sources to generate the illuminating strip on the surface of the material, which is displaced in relation to the device. The illuminating device includes a mirror which focuses the light emitted by the light source into the illuminating strip, a diffusion body on the light emission side facing the surface of the material. The light sources feed their light into the reflector module. That module, the diffusion body, and the mirror are configured as a single component.
Claims85
An optical system usable to produce an illuminated strip on a surface of a material comprising:
- an illumination device including a plurality of light sources spaced at a distance from the surface and usable to emit light to produce said illuminated strip on the surface of the material;
- means supporting the material for selective movement with respect to said illumination device in a movement direction;
- at least one reflector module in said illumination device and located between, in a path of light from said plurality of light sources, said light sources and the surface;
- at least one mirror and a diffuser in said at least one reflector module, said at least one mirror concentrating said light emitted by said light sources onto the surface to produce said illuminated strip, said diffuser being located on a light exit side of said illumination device in said at least one reflector module;
- and
- an illuminated strip length and an illuminated strip width, said illuminated strip width extending in said movement direction of the material, said light emitted from said light sources having a first concentration in said illuminated strip length and a second concentration in said illuminated strip width, said first concentration being greater than said second concentration.
An optical system usable to produce an illuminated strip on a surface of a material comprising:
- an illumination device including a plurality of light sources spaced at a distance from the surface and usable to emit light to produce said illuminated strip on the surface of the material;
- means supporting the material for relative movement with respect to said illumination device in a movement direction;
- at least first and second illumination modules in said illumination device and each having at least one of said light sources, said illumination modules being arranged side by side;
- and
- a control for said illumination device and usable to control said at least one light source in each of said at least first and second illumination modules independently of each other.
An optical system usable to produce an illuminated strip on a surface of a material comprising:
- an illumination device including a plurality of light sources spaced at a distance from the surface and usable to produce said illuminated strip on the surface of the material, said plurality of light sources being arranged in a longitudinal direction of said illumination device;
- means supporting the material for movement in a movement direction relative to said illumination device;
- and
- a control device for said illumination device and usable to control at least one of said plurality of light sources independently of at least another one of said light sources arranged in said longitudinal direction of said illumination device.
