Electrical reflector lamp

摘要

The electrical reflector lamp according to the invention has a blown lamp vessel (1) comprising a light-transmitting part (4) opposite to a neck-shaped part (3). The lamp vessel (1) has a first mirror-coated lamp vessel portion (5), which has a spherically curved part (14) and a paraboloidally curved part (15), and further a second mirror-coated lamp vessel portion (7), which is curved paraboloidally. A paraboloidally curved reflector (8) is arranged in the neck-shaped lamp vessel portion (3). The foci of the paraboloidal parts and the reflector and the center of the spherical part coincide (6). The light source is arranged in a plane (12) through the foci (6) and transversely to the axis of symmetry (2) of the lamp vessel (1). A very large part of the generated light is irradiated by the lamp in a concentrated beam.
