The electric reflector lamp has a reflector body with a neck. A lamp vessel containing an electric element is secured in the reflector body, held by a mounting member which has a securing portion. A lamp base is secured around the neck. The mounting member has a circumferential wall which surrounds the neck and which has relief cooperating with relief of the neck so as to couple the circumferential wall to the neck. Elastic elements of the circumferential wall seize in the recesses in the ceramic lamp base so as to secure the base. The reflector lamp is readily assembled using a small number of components.

An electrodeless low-pressure discharge lamp according to the invention has a lamp vessel (1) which is closed in a gastight manner, which contains an ionizable filling, and which has a cavity (10). In the cavity (10) an elongate coil (2) is positioned with a primary and a secondary winding (21, 22, respectively) of an electrical conductor (20) around a coil former (3) which has a tip (30) which points into the cavity (10). The electrical conductor (20) from which the secondary winding (22) is formed extends from a first end (22a) of the secondary winding (22) facing the tip (30) into a recess (32) of the tip (30) of the coil former (3) and is clamped therein. The first end (22a) of the secondary winding (22) can be easily fastened in this manner.

An electric lamp according to the invention comprises a lamp vessel (10) which is closed in a gastight manner, which has an end portion (11), and which surrounds a light source (12). The lamp vessel supports a cylindrical collar (30) with an axis (31) at its end portion (11). One or several projections (33a, 33b, 33c) of a first coupling member (30) which each grip into a respective recess (41a, 41c) of a second coupling member (40) couple the collar (30) to a mounting member (40) for fastening the lamp to a carrier. At least one of the coupling members (30) is made of an elastic material. The second coupling member (40) has two or more axial zones (43, 43') each with at least one recess (41a, 41b, 41c; 41a', 41b, 41c') and a raised step (42a, 42b, 42c; 42a', 42b', 42c') which bounds the recess in tangential direction, while a raised step (42a, 42b, 42c) of an axial zone (43) also forms part of an axial boundary of a recess (41a', 41c') of an adjoining axial zone (43') each time, and the raised steps and the one or several projections (33a, 33b, 33c) have mutually self-locating shapes in at least one tangential direction. The construction of the lamp according to the invention renders it possible to remove the lamp vessel from the mounting member without the use of a tool, but counteracts an inadvertent removal.

The push-in/push-out lampholder has a guide track for an unlocking member which is permanently coupled to a fixation member. The guide track may be heart-shaped and be partly traversed by the unlocking member when a lamp cap is pressed into the lampholder. The lamp cap must be released if it is to reach an operational position under the influence of a spring. The fixation member permanently coupled to the unlocking member is then in engagement with a profile of the lamp cap and retains the lamp, pressed against contact members. It is not until a second, separate push is given that the unlocking member continues its path through the guide track. In a special embodiment, the fixation member and the unlocking member are combined into an integrated member, which may be a ball which is enclosed in inwardly narrowing bores of a cylindrical ball holder and in the guide track. The lampholder can be slim and can be manufactured mainly from metal or from synthetic resin.
