Definitions
- the invention relates to a lamp according to the preamble of claim 1.
- the invention relates in particular to an electric lamp, comprising a built-in lamp arranged in an outer bulb and a base, wherein the base is electrically connected to power supply wires of the built-in lamp.
- the invention further relates to a single-ended electric lamp with an outer bulb supported in a base and at least one inner bulb disposed within the outer bulb.
- Such halogen incandescent lamps are intended in particular for operation on high voltage (HV) with typically 100 to 250 volts.
- HV high voltage
- DE-A 10 2005 051 076 discloses a holder for a built-in lamp, which consists of a metallic mounting clip, in which the built-in lamp is inserted.
- the mounting clip is attached to the glass plate base of the outer bulb, which is very expensive, since the glass base is a very complex component, which includes, for example, exhaust tube and melted supply wires.
- the object of the present invention is to ensure a mounting of a built-in lamp on a disc base with the shortest possible length.
- the invention ensures the simple production of a lamp, consisting of a built-in lamp, a base and an outer bulb.
- the invention provides a single-ended electric lamp with an outer bulb fastened to a base and an integral lamp arranged inside the outer bulb, which is robust and easy to produce.
- the integral lamp is a high-voltage halogen incandescent lamp with pin base, wherein at least two pins act as power supply wires.
- the built-in lamp consists essentially of a hermetically sealed lamp vessel, at least one light source and a power supply system for the light source, which usually consists of two pins, which protrude from a pinch of the integral lamp parallel to the axis.
- the light source is usually a filament, but it can also be a discharge arc between two see electrodes. In the following, the light source will always be described as a luminous element for the sake of simplicity.
- the power supply system connects the lamp arranged in the interior of the lamp vessel with a lamp arranged outside the base, which is to be connected to a power source.
- the power supply system consists, for example, of inner power supply wires, fusible films and outer power supply wires, wherein the aligned ends of the inner and outer power supply wires and the fuse sheets connecting the power supply wires are fused together in the lamp crimp.
- Relevant to the invention is only the pinch and the outwardly projecting pins.
- the built-in lamp is usually filled with an inert gas and a halogen additive. Instead of a light bulb but also a high-pressure discharge lamp can be used as a built-in lamp, similar to that described in DE-A 32 32 207.
- the joke of the invention is that a high degree of compacting is achieved in that the external power supply lines of the built-in lamp are not connected directly to the base as hitherto, but rather via a mounting clip which, so to speak, folds the connecting line and so on Length of the lamp shortened.
- the external power supply of the integral lamp ends as short pins (pins).
- the mounting clip contacts a pin via a contact part.
- he has a hollow rail, which is connected via a frame part with the contact part. This hollow rail is connected by a clip connection with a base pin, which protrudes from a Tellerfuß upwards.
- the novel mounting clip has as essential components a contact surface for the external power supply to the contact part, acting as a connection frame member and a hollow rail, which is connected to the contact part via the frame part.
- the frame part is designed in particular in the manner of a window frame, that is essentially a quadrilateral, which is recessed inside to save material.
- the quadrilateral is not necessarily planar, but it can advantageously be curled to improve stability.
- the frame part is preferably constructed from two longitudinal struts and two transverse struts.
- the contact part is substantially preferably an extension of a first longitudinal strut downwards, facing away from the pinch.
- the contact part is like a lath, the contact surface is located at the end of the contact part. It may be formed spade-shaped or ridge-like, by one side of the contact surface is chamfered and there is an overhang protruding. This arrangement serves to spread the end of the external power supply.
- the frame has a slightly angled threading aid attached to the first longitudinal strut. It protrudes opposite to the contact part on the first longitudinal strut.
- the hollow rail runs parallel to the second longitudinal strut. It is U-shaped in cross-section and is integral with a leg of the U on the second longitudinal strut. In this case, this leg is angled approximately at right angles out of the plane of the frame part.
- This hollow rail is adapted to closely surround the projection of the base part. For temporary fixation, the hollow rail can be broken in the region of the second free leg, so that a clamping piece is released from the flesh of the second free leg, since it can be pressed inwards against the base part and thus pressed against the base part.
- another second frame part is attached to the second free leg, which corresponds approximately to the first frame part.
- This second frame part preferably also has a threading aid, mirrored to the first threading aid. It can be designed as a spring part by being corrugated. Overall, this second frame part serves for better fixation, stabilization and distribution of forces in the holder by being arranged over a wide area on a broad side of the pinch seal.
