ABSTRACT:
Given a reflector arrangement in a device that is employed for the individual illumination of objects, high demands must be made of the durability of the mirror layers to be applied onto carriers. Considerable difficulties result in satisfying this demand, particularly given large-area reflector arrangements which are exposed to weather. In order to overcome these difficulties, the reflector arrangement is designed with shell carriers of transparent material that are designed tub-shaped and which have a vapor-deposited mirror layer provided on the side of the shell. This mirror layer is durably protected with suitable cover techniques against environmental influences which deteriorate or destroy it.
