Description

The invention relates to a lamp socket for a lamp which is suitable for connection to a reflector. When the connection is made, a device is produced which has a lamp socket and a reflector. The device is intended for installation in a luminaire.

There are various units with a lamp holder and a reflector known. For example disclosed DE 8 323 476 U1 a lamp holder, on whose side facing away from the light source, a radially projecting mounting flange is provided. Latch hooks in a pot-shaped luminous reflector can overlap this mounting flange to make a connection between the lamp socket and reflector. The disadvantage here is that the lamp socket is arranged within the reflection range of the reflector.

Out DE 100 47 407 A1 such as DE 100 47 409 A1 In each case, a recessed luminaire with a reflector unit and a device box attached to the reflector unit is known. A socket carrier and a rail serve as a lamp holder, are held on the two lamp holders. The structure is complex and consists of many individual parts. Such a recessed light is therefore expensive.

Another recessed ceiling light is in DE 4 344 376 A1 described. A base housing 1 of a ring and a plurality of struts is used to receive a reflector 12, for example, characterized in that a locking knob passes through a mounting recess in the reflector roof and is locked there in a manner not shown. Through a lateral recess in the reflector, the bulbs are introduced into the reflector interior. In the area of this recess, a socket carrier is attached to the base housing containing the sockets for the bulbs. Such a design requires a lot of space and is expensive to produce.

Out DE 90 02 923 U1 is a lamp with a cup-shaped housing known. On the housing, a lid for realizing a strain relief for the connection cable can be fastened in a snap. Coaxial with a plug-in area for a halogen lamp, a hollow cylindrical projection is provided on the housing, which can serve for attaching a reflector. How to attach the reflector to the housing is not described.

The lamp holder and the reflectors are included US 3,763,456 made in one piece from a single piece. This embodiment is suitable for very specific applications, such as vehicle lights, in which the arrangement remains unchanged. The disadvantage is that the lamp socket can not be combined with different reflector types.

Out US 5,272,409 It is also known to produce a structural unit from a lamp and a reflector. A lamp socket is not described.

An inserted through an opening in a reflector through the lamp socket is also off US Pat. No. 7,147,532 B2 known. An annular flange of the lamp socket rests in a cylindrical recess on the back of the reflector. A more detailed description of the attachment between the lamp socket and reflector can not be found in this document. In addition, the lamp socket engages in the reflection area in the interior of the reflector.

In DE 40 14 801 A1 a lamp socket is described in which the socket body is inserted via a U-shaped double leg spring in a hole of a reflector, wherein the double leg spring engages in the hole of the reflector. The double leg spring is attached to a dome-like projection on the socket body. The double leg spring and parts of the socket body protrude into the interior of the reflector.

The DE 199 24 355 A1 describes a lamp with a reflector, wherein a gas discharge lamp can be inserted as a light source through an annular reflector neck. To fix the gas discharge lamp to the reflector is a sleeve which is attached to the base of the gas discharge lamp and a sleeve which connects the sleeve with the reflector neck of the reflector. For this purpose, inwardly projecting spring tongues may be formed on the sleeve, which engage in a groove on the reflector neck. The structure of a socket body for the gas discharge lamp is not described in detail. To connect the reflector with the light bulb here serves the cuff and the sleeve. The light source should thereby be moved relative to the reflector and can be aligned.

A reflector for a light is also off DE 86 08 895 U1 known. The reflector has a cylindrical neck with a circumferential groove. A socket body of a lamp socket can engage through the neck in the reflector and be secured in the groove of the reflector neck by means of leaf springs, which are fixed to the bottom of the socket body. To attach the leaf spring to the socket body fasteners are necessary, which are formed by screws. The leaf spring stands out from the socket body. The socket body itself is not described in detail.

Further shows DE 72 36 536 U1 a recessed luminaire with a lamp holder, on the outside of a reflector is releasably secured via a plurality of resilient retaining webs. The holding webs are connected to the reflector and engage around a radially thickened end of the socket body.

Finally describes DE 22 36 648 A the connection of two sleeve-shaped components with a small wall thickness. In one exemplary embodiment, a cup-shaped body for holding a light bulb is provided in a headlight and attached to an inner cylinder of the headlight. A socket for the light bulb is riveted to its end facing away from the bulb with a disc. This disc is acted upon by leaf springs over which the disc and thus the socket on the cup-shaped body is supported. The socket or the light bulb can be displaced by elastic deformation of the leaf springs along the optical axis. By further adjustment screws pivoting of the socket or the bulb is also possible.

Starting from the prior art, it can be regarded as an object of the present invention to provide a lamp socket for connection to a reflector, which can be easily produced and does not interfere with the connection made to the reflector, the light reflections on the reflector inside.

This object is achieved by a lamp socket with the features of claim 1.

The lamp socket has a socket body with a receiving opening. This receiving opening is limited in the circumferential direction at least in sections by an inner wall portion of the socket body. In the receiving opening a lamp can be inserted. The lamp socket is preferably designed as a pin socket. The receiving opening simultaneously serves to receive a fastening portion of the reflector. This attachment portion may for example be an annular, hollow cylindrical portion which can be inserted coaxially to the optical axis in the receiving opening. As a result, the lamp holder is arranged on the back of the reflector. It does not protrude into the interior of the reflector. The attachment portion is disposed in the use position between the lamp and the inner wall portion of the receiving opening.

From the inner wall portion protrudes a locking element into the receiving opening. The latching element serves to act on the fastening section of the reflector in order to hold the reflector on the socket body. For this purpose, a cooperating with the locking element locking counter-element is provided on the attachment portion. In the position of use, the locking element and the associated locking counter-element produce a releasable or non-releasable locking connection. The reflector is thus held directly on the socket body. As a result, a very simple and space-saving construction of the lamp can be realized. The hole in the reflector, through which protrudes the lamp into the interior of the reflector, can be chosen very small. The reflection of light caused by the reflector is therefore large. Only the bulbs protrude into the interior of the reflector.

The positioning between the socket body and the reflector is effected by the projecting into the receiving opening mounting portion of the reflector. The latching means and the counter-locking means only serve to connect the reflector and the lamp holder captive with each other. For the locking means and the locking counter means larger tolerances are therefore possible, which simplifies the production of the lamp holder and the reflector. To improve the relative position and the alignment between the socket body and the reflector, an elastic means, for example an O-ring in the region of the receiving opening between the reflector and the socket body can be provided. This elastic means may be arranged in the region of the inner wall section of the socket body and / or on the end wall of the socket body which surrounds the receiving opening in an annular manner. The elastic means can compensate for any existing clearance between the reflector and the lamp socket.

In the inner wall portion, an opening is present through which the latching means projects into the receiving opening. The latching means is preferably formed by a particular pivotable latching projection. For example, the locking counter-element can be configured as a detent hole. The locking element is biased by a spring element in its locking position in which it protrudes into the receiving opening. The locking element and the spring element are designed in one piece. The locking element and the spring element are made of a single material without seam or joints as a common locking body. This locking body is preferably made of metal and in particular of spring steel. The socket body may be made of plastic or ceramic, for example.

The lamp holder has a plurality of latching elements, which protrude evenly distributed in particular in the circumferential direction in the receiving opening. In this case, several and in particular two latching elements can be connected to a common spring element. The spring element points for example, a bow-like shape, wherein the two locking elements are provided on the strap ends.

In an easy-to-manufacture lamp socket in the socket body an insertion exists, in which the catch body can be inserted. The insertion opening is preferably connected to the opening through which the latching element can engage in the receiving opening.

Adjoining the receiving opening in the interior of the socket body is a contact area, which serves for producing the electrical connection between a connection cable and the lighting means. The contact area is separated from the insertion opening. A partition wall of the socket body is present between the insertion opening and the contact area.

The lamp socket may further comprise a strain relief. The strain relief is used to strain relief of an electrical cable connected to the lamp socket. Preferably, the strain relief is provided on the receiving opening opposite the back of the lamp socket. The strain relief can be formed by means of a releasably connectable to the socket body lid. In a preferred embodiment, this cover can simultaneously serve to cover the rear side of the socket body, so that the connection area between socket body and cable is protected.

The lamp holder associated reflector has a mounting portion with the locking counter-element. Preferably, the attachment portion is configured as a hollow cylindrical collar or ring. Coaxially thereto, a hole is provided in the reflector, through which protrudes the lamp in the use position in the interior of the reflector. Such a reflector is very easy to connect to the lamp socket and inexpensive to manufacture. The size of the hole can be adapted to the size of the lamp, so that the reflective inside of the reflector comes close to close to the bulb. The radiation power is thereby very large.
