Title (EN) LIGHTING DEVICE AND METHOD FOR MOUNTING THE LIGHTING DEVICE
(FR) DISPOSITIF D'ECLAIRAGE ET PROCEDE ET MONTAGE DE CE DISPOSITIF D'ECLAIRAGE
Abstract:
(EN) The invention concerns a light fitting consisting of a power unit (1), a light source (2) powered by the power unit, a reflector (3) connected to the light source and working with it, and a light pipe (6) connected to the reflector. The invention also concerns a procedure for the installation of such a light fitting. In the case of cold-storage rooms, for example, on account of energy costs, it is desirable to locate the power source, light source and reflector outside the cold-storage room and arrange for the light to be transmitted through the wall. In order to avoid problems connected with the leakage of heat, condensation and the formation of ice, the light fitting according to the invention is designed so that the end of the light pipe (6) facing the reflector is provided with a surrounding insulating pipe (5) and so that there is a plate (8) that is transparent to the wavelength range of the light source at the junction between the reflector (3) and the light pipe (6), which transparent plate is designed to form an airtight seal with the light pipe (6) and provide a seal with the surrounding insulating pipe (5).
(FR) L'invention concerne un dispositif d'éclairage comprenant un bloc d'alimentation (1), une source lumineuse (2) alimentée par le bloc d'alimentation, un réflecteur (3) raccordé à la source lumineuse et coopérant avec cette dernière, et un conduit de lumière (6) raccordé au réflecteur. L'invention concerne la procédure d'installation d'un tel dispositif d'éclairage. Dans le cas, par exemple, de dépôts frigorifiques, il est souhaitable, pour des raisons de coût d'énergie, de placer la source d'énergie, la source de lumière, et le réflecteur, à l'extérieur du dépôt frigorifique et d'assurer la transmission de la lumière à travers le mur. Pour éviter les problèmes liés à la déperdition de chaleur, à la condensation, et au givrage, l'extrémité du conduit de lumière (6) faisant face au réflecteur est dotée d'un tube isolant (5), et une plaque (8) transparente aux longueurs d'onde de la source de lumière est placée à la jonction entre le réflecteur (3) et le conduit de lumière (6), ce qui forme une fermeture étanche à l'air sur le conduit de lumière (6) et constitue un joint avec le tube isolant (5) enveloppant.
