Abstract
The invention relates to an irradiation device for irradiating objects, comprising a housing having an outlet for the electromagnetic radiation directed at an object to be irradiated and at least one long radiation source for the electromagnetic radiation arranged in the housing. In order to enable bigger irradiation widths in an irradiation device, more particularly in a UV irradiation device, without deformation of the radiation source, at least one of the radiation sources in the irradiation device is rotationally arranged about its longitudinal axis.
Claims11
An irradiation device for irradiating objects with electromagnetic radiation, said device comprising:
- a housing having an interior and an outlet aperture;
- at least one elongate radiation source arranged in the housing;
- an admission channel having a cooling gas admission aperture extending parallel to said radiation source;
- a sieve located between said admission aperture and said interior of said housing;
- a discharge channel having a cooling gas discharge aperture extending parallel to said radiation source opposite from said admission aperture;
- a sieve located between said discharge aperture and said interior of said housing;
- a surface partly enveloping said radiation source and forming a gap which converges toward the cooling gas discharge aperture;
- and
- an elongate barrier between said radiation source and said outlet aperture, said barrier forming one of said channels, said barrier comprising curved reflector elements facing the radiation source.
An irradiation device 3 further comprising a contactless supply of power for operating at least one said elongate radiation source which is rotatable about its longitudinal axis.
A method for operating an irradiation device of the type comprising:
- a housing having an interior and an outlet aperture;
- at least one elongate radiation source arranged in the housing, each said elongate radiation source having a longitudinal axis and a pair of opposed ends, at least one said elongate radiation source being rotatable about its longitudinal axis;
- an admission channel having a cooling gas admission aperture extending parallel to said radiation source;
- a sieve located between said admission aperture and said interior of said housing;
- a discharge channel having a cooling gas discharge aperture extending parallel to said radiation source opposite from said admission aperture;
- a sieve located between said discharge aperture and said interior of said housing;
- a surface partly enveloping said radiation source and forming a gap which converges toward the cooling gas discharge aperture;
- and
- an elongate barrier between said radiation source and said outlet aperture, said barrier forming one of said channels, said barrier comprising curved reflector elements facing the radiation source;
- wherein said method comprises rotating each said rotatable radiation source and at least one of periodically changing the direction of rotation and rotating the radiation source in only one direction.
