The invention relates to a method for optical fiber use, in which light that is generated by means of a light generating apparatus is being led by exploiting an optical fiber, wherein the light generating apparatus has at least light generating means (1), such as a lamp (1a) and an objective assembly (1b) and/or like to direct light towards the end of the optical fiber (2), for leading of the same further by the optical fiber (2). Particularly for cooling of the input end for light (2a) of the optical fiber the same is being cooled convectively, by directing an air flow (w), that has been cooled by means of a cooling device (3) operating preferably by Peltier-phenomenon to the same. The invention relates also to a light generating apparatus exploiting the method.
L'invention concerne un procédé d'utilisation de fibre optique. On achemine via une fibre optique la lumière générée par générateur de lumière. Le générateur de lumière comprend au moins un organe générateur de lumière (1), tel qu'une lampe (1a), et un ensemble objectif (1b) et/ou un organe permettant de canaliser la lumière vers l'extrémité de la fibre optique (2), pour acheminer la lumière via la fibre optique (2). En outre, pour refroidir l'extrémité d'entrée de lumière (2a) de la fibre optique, on refroidit cette extrémité par convection en y envoyant un courant d'air (w), qui a été refroidi par un dispositif de refroidissement (3), de préférence, à effet Peltier. L'invention concerne aussi un générateur de lumière qui met en oeuvre le procédé.
