Abstract
The present invention provides a lamp comprising a lamp body formed by one single device component. The device component is formed of a foil made of a bendable, elastic material. The foil exhibits a bending line near a center of the foil. The foil contains an opening for receiving the illuminating device and/or current-carrying parts. The foil is formed to a curved, central wave fold by exerting a light pressure from two sides toward the center of the foil based on the bendable and elastic properties of the foil. The curved, central wave fold ends at said bending line. The foil assumes a cap-like spatial structure based on a partial deformation along the bending line caused by the light pressure. The cap-like or hood-like foil can be then easily fixed in this spatial structure by means of a suitable tightening, clamping, or locking device. The entire lamp body is stable and fixed in this spatial structure.
