1. A wide-area lamp wherein:
- a plurality of luminescent semiconductor elements in a wide-area spread are mounted directly on and connected to one another by a conducting path structure;
wherein each semiconductor element and an adjacent respective portion of said connector path structure is surrounded by a respective casing element;
the casing elements are surrounded in part by respective reflectors; and
the conducting path structure between said individual casing elements is movable such that the lamp can be curved to the shape required.

Abstract
The invention relates to a wide-area lamp in which luminescent semiconductor elements in a wide-area spread are connected to one another by a conducting path structure and the individual luminescent semiconductor elements are surrounded by casing elements. The invention provides for the conducting path structure between the individual casing elements to be designed movable such that the lamp can be curved to any shape required. The casing elements are here surrounded by parabolic reflectors, with the conducting path structure with the semiconductor elements being so arranged that one semiconductor element is in the focal point of each reflector.
