Electric light source with reflector, reflector, and glass-moulded piece for use therein.

摘要

The electric light source with reflector comprises a reflector (10) having a first and a second mirroring wall portion (12 resp. 22), which in axial sections are curved according to an arc (13 resp. 23) of a circle the centre of which lies before the plane P of the largest diameter (d), in an area extending predominantly at the other side of the axis, and behind plane P at the other side of the axis, resp. The reflector has a light emanating window (30) opposite to a lamp base (1). An electric light source (3) is disposed within the reflector (10) near plane P and the axis (11). The reflector (10) may be integrated with a lamp vessel (5) to give a reflector lamp. The invention also concerns a reflector having a lamp holder to receive an electric lamp suitable for use in the electric light source with reflector and to moulded glass bodies suitable for use in the reflector. The second and possibly the first wall portions (22, 12) have superimposed, tilted and transversely concave axial lanes (25 resp. 15), which prevent reflected rays to hit the light source and causing stray radiation. The lanes 15 may counteract or augment the deviation given to light rays by lanes 25. The reflector may be adjustable by its user. <IMAGE>
