Title (EN) DEVICE FOR SOFT IRRADIATION
(FR) DISPOSITIF POUR L'IRRADIATION AVEC DES RAYONNEMENTS MOUS
Abstract:
(EN) A device for soft irradiation comprising a reflector (10) having a cross-section in the shape of a spiral and an electromagnetic radiation source (12) positioned off-axis such that the source is shielded from direct view. A cooling vent (14) and openings (16) provide impingement cooling of the source to allow efficient use of a high intensity radiation source. Cooling of the source may be further improved with the addition of one or more fluid moving devices in flow communication with the reflector. Optical reflectance coatings (20) on the surface of the reflector or transmission filters (32) allow the device to provide radiation output in selective bandwidths. Multiple reflectors may be used in combination to evenly illuminate complex or large surfaces. There are specific utilities to this design with both pulsed and continuous light sources.
(FR) Un dispositif d'irradiation par rayonnements mous comprend un réflecteur (10) dont la section transversale a la forme d'une spirale et une source (12) de rayonnement électromagnétique qui est placée hors-axe afin que la source soit protégée de la vue directe. Un orifice (14) et des ouvertures (16) de refroidissement assurent le refroidissement par incidence de la source pour que la source de rayonnement à haute intensité soit utilisée de manière efficace. Le refroidissement de la source peut être également amélioré lorsqu'on ajoute un ou plusieurs dispositifs à déplacement de fluide qui communiquent par le fluide avec le réflecteur. Des revêtements (20) à réflectance optique situés sur la surface du réflecteur ou des filtres (32) d'émission permettent au dispositif de produire des rayonnements de sortie dans des largeurs de bande sélectives. Plusieurs réflecteurs peuvent être utilisés en combinaison pour illuminer uniformément des surfaces complexes ou de grandes dimensions. Ces fonctions sont donc les fonctions spécifiques à ce dispositif aussi bien avec des sources de lumière continue que de lumière pulsée.
