Description

The invention relates to a lamp holder and a method for mounting the lamp holder. The luminous means holder is used for arranging at least one semiconductor illuminant, for example a light-emitting diode or a light-emitting diode, on a luminaire component.

For this purpose, various lamp holders are known.

US Pat. No. 6,184,628 B1 describes a lamp holder with a light source carrier having a light emitting surface on which a plurality of light emitting diodes are arranged. The illuminant carrier is fastened via a screw connection to a holding part. The holding part has an encircling edge which completely surrounds the illuminant carrier and on which a cover part is placed.

Out WO 2010/101405 A2 For example, a light source holder is known which has a light source carrier with a plurality of light emitting diodes arranged on a light source surface. The illuminant carrier is attached via a central hole on a pin of a connecting element. The connecting element is seated in a central recess of a holding part, in which the illuminant carrier is inserted. The holding part has an edge with an internal thread. A cover can be screwed to the edge of the holding part. The illuminant carrier can be fastened by screws on the holding part or on a further plate-shaped element.

Out DE 10 2006 015 839 A1 is a bulb holder for a kitchen light known. The illuminant holder has two illuminant carriers, on each of which semiconductor illuminants are arranged. The two illuminant carriers are fastened via respectively associated latching elements in a housing lower part. With the lower housing part, an upper housing part is connected, which has a transparent pane. The connection between the two housing parts takes place via a latching connection.

US 2010/0208474 A1 describes a luminaire housing with two housing parts which are screwed together. A light source carrier with bulbs can be clamped between the two housing parts, when the two housing parts are screwed together.

A similarly to be mounted bulb housing is also in DE 10 2009 047 493 A1 described. A light source carrier with bulbs is partially covered by a ring cover. There are openings in the ring cover to secure the ring cover and illuminant carrier to a heat sink.

Starting from the known prior art, it can be regarded as an object of the invention to provide a light source holder which allows easy mounting and in particular allows a tool-free insertion or removal of at least one light source.

This object is achieved by a bulb holder with the features of claim 1 and a method for mounting the bulb holder with the features of claim 12.

According to the invention, the luminous means holder has a luminous means carrier with a luminous means surface for attaching the at least one semiconductor illuminant. Preferably, a plurality of semiconductor illuminants, such as light-emitting diodes or light-emitting diodes, are arranged on the illuminant surface and are electrically contacted via conductor tracks and / or bonding wires. The illuminant carrier has a plate-like shape and is preferably formed by a printed circuit board. For storage of the illuminant carrier, the luminous means holder has a holding part which serves for mounting the illuminant holder on a luminaire component. The assembly can be done for example via connectors and / or latching connector and / or screws and is preferably detachable. As a luminaire component, a luminaire housing, a lampshade, a heat sink or the like can be used.

On the holding part, a holding device is present. The holding device stores or holds the illuminant carrier during assembly preferably non-positively and / or positively. Preferably, the holding device has at least one clamping means which exerts a clamping force on the illuminant carrier approximately parallel to the illuminant surface. In particular, the illuminant carrier can be held by the holding device in a pressing direction at least in a certain range of movement movable.

The lamp holder also has a cover with a radiation opening. The emission opening can have any desired contour and can be designed, for example, as polygonal or circular. In the circumferential direction, the emission opening on the side facing the light source carrier of the cover is limited by a Andrückanordnung with at least one Andrückkörper. The Andrückanordnung may for example have an annular Andrückkörper, which surrounds the radiating completely annular. Alternatively, for example, a plurality of Andrückkörpern preferably regularly distributed in the circumferential direction to be arranged around the emission opening.

To the bulb holder also includes a fastening device. The fastening device is arranged on the cover part and / or on the holding part. It serves to releasably secure the cover to the holding part. When produced attachment between the cover and the holding part presses the at least one Andrückkörper the Andrückanordnung immediately adjacent to the illuminant surface on the illuminant carrier, preferably at a distance from the edge of the illuminant carrier.

As a result of the embodiment according to the invention, a pressing force is generated on the illuminant carrier away from the cover part and, in particular, towards the luminaire component through the one or more pressure bodies. As a result, the illuminant carrier with its rear side opposite the illuminant surface is pressed against a luminaire component, for example a luminaire sheet or a heat sink. This pressing force is generated immediately adjacent to the at least one semiconductor illuminant around the illuminant surface. As a result, good flat contact between the illuminant carrier and a luminaire component is ensured during operation of a luminaire, which leads to good heat dissipation of the heat generated by the at least one semiconductor illuminant. In particular, a tool-free final assembly is possible. Only the attachment of the holding part to a lamp component can preferably be realized via a screw, wherein a tool is required. The insertion, removal or replacement of a luminous means carrier with the semiconductor illuminants arranged thereon takes place in particular without tools and can therefore be performed quickly and easily by an operator. The pressing force between the at least one pressing body and the illuminant carrier is generated when attaching the cover on the holding part with the fastening device.

Preferably, the holding part is designed as a holding frame with a holding recess. The support frame can completely enclose the retaining recess. The contour of the retaining recess is in particular set so that the illuminant carrier can be arranged in the holding recess and enclosed by the holding frame. About the retaining recess a contact of the illuminant carrier is guaranteed with a lamp component for heat dissipation in a simple manner and can be done directly and directly in particular without the interposition of other components.

In a preferred embodiment, the holding device has one and preferably a plurality of clamping means. The clamping means act on the illuminant carrier in order to hold it on the holding part by a clamping force. The clamping force is generated in particular in a direction transverse to the pressing direction and parallel to the plane of the illuminant surface. It is possible to generate clamping forces in one or two spatial directions. For example, the clamping force can clampingly hold a plate-shaped illuminant carrier between its opposite side edges. By virtue of this clamping bearing, movability of the illuminant carrier in the pressing direction is possible, at least in a certain range, so that it can be ensured via the pressing force that the illuminant carrier is pressed flat against a luminaire component for heat dissipation, which serves as a heat-dissipating body.

The fastening device establishes a non-positive and / or positive, releasable connection between the cover part and the holding part. This connection is preferably without tools produced and solvable.

In a preferred embodiment, the cover member may be annular. About the fastening device, it is preferably rotatably mounted relative to the holding part. The releasable connection is established or released by a relative rotational movement in a circumferential direction about the emission opening.

The fastening device has at least one fastening surface on the retaining part and in each case an associated counter-fastening surface on the cover part. Two mutually associated surfaces cooperate to produce the releasable connection together and are in manufactured attachment to each other. The at least one fastening surface and / or the at least one counter-fastening surface has a first surface section inclined in the circumferential direction and an adjoining second surface section which is inclined in the circumferential direction.

The attachment surface is provided on an elastic attachment projection of the holding part. This elasticity can produce an elastic deformation force with which the attachment surface presses against the respectively assigned counter-fastening surface when the connection is made.

The holding part with fastening projections is preferably made of a uniform material without seams and joints. It may in particular consist of metal. In one embodiment, the holding part can be punched out and brought into the desired shape by a forming process, in particular by bending.

In a relative rotation of the holding part relative to the cover for producing the attachment, the respectively assigned other surface first slides along the inclined first surface portion, while the pressing force is increased until the two associated surfaces in the region of the second surface portion abut each other, so that a further rotation in Circumferential direction no increase in the pressure force causes more. As a result, it is easy and safe to produce an attachment of the cover part on the holding part and to specify a maximum pressing force, so that no components of the illuminant holder can be damaged by an excessive pressing force.

In a preferred exemplary embodiment, the illuminant carrier outside the illuminant surface has a connection surface for attaching an electrical connection component, for example a plug component. The cover part may have a connection recess for the connection component. Preferably, the connection recess is larger in the circumferential direction than the connection component, so that a free space for a relative rotation of the cover relative to the holding part is possible when the connection member protrudes into the connection recess.

When produced attachment between the cover and the holding part of one of the Andrückkörper or a portion of a Andrückkörpers the Andrückanordnung between the pad and the illuminant surface abut the illuminant carrier. As already described, it is ensured that the pressing force is generated close to the illuminant surface or the at least one semiconductor illuminant in order to be able to achieve optimum heat dissipation. In addition, the at least one semiconductor illuminant can thereby be protected from accidental damage when handling the electrical connection on the connection component.

The cover part may preferably be arranged in the region of the emission opening a component for guiding the light. For example, it is possible to arrange a reflector on one or more sides of the emission opening. Additionally or alternatively, the emission opening can be covered or closed by a disk. The disk is permeable to the light wavelength emitted by the at least one semiconductor illuminant. One or more lenses can also be integrated or arranged in or on the pane. It is also possible to integrate reflection surfaces and / or reflection particles and / or scattering surfaces and / or scattering particles or the like into the pane.

In order to facilitate the rotation of the cover relative to the holding part, handle parts and / or engagement recesses may be present. The grip parts or engagement recesses may be designed to be operated by hand and / or a tool.

In the 1 . 2 . 6 and 7 are exemplary embodiments of a lamp holder 10 illustrated. The components and the mounting of the bulb holder 10 arise from the 3 to 6 as well as the partially cut representation of the 7 ,

The bulb holder 10 has a light source carrier 11 with a bulb surface 12 on. The illuminant carrier 11 can be formed for example by a printed circuit board. Alternatively, the illuminant surface 12 also be present on a heat sink. The illuminant carrier 11 is preferably made of a material having good thermal conduction properties. The example as a light source 11 Serving circuit board may be made of aluminum or have an aluminum core. Alternatively, the circuit board may also comprise ceramic material or consist of ceramic.

At the bulb area 12 is at least one semiconductor illuminant 13 and, according to the example, a plurality of semiconductor illuminants 13 arranged. As a semiconductor illuminant 13 For example, light-emitting diodes and / or light-emitting diodes can be used. The semiconductor illuminants 13 are directly on the bulb surface 12 of the illuminant carrier 11 attached and via tracks 14 or other electrically conductive means, such as bonding wires, electrically contacted.

The the bulb surface 12 having side of the illuminant carrier 11 represents the top 15 on the top 15 is outside the bulb area 12 a connection surface 16 available. The connection surface 16 is used to attach one or more electrical connection components to the semiconductor illuminants 13 electrically connect with an operating device or ballast, via which the semiconductor light elements 13 be supplied with electrical energy and / or controlled during operation. In the embodiment is as an electrical connection component on the pad 16 a plug component 17 arranged, via which an electrical line with the conductor tracks 14 and therefore with the semiconductor lamps 13 can be electrically connected.

To the bulb holder 10 also includes a holding part 20 , separately in 3 is illustrated. The holding part 20 serves to the bulb holder 10 to attach to a lamp component, not shown, for example, a lamp board, a lamp housing, a heat sink or other component of a lamp. The attachment can be done in principle in various ways, for example via plug connection means, latching connection means, Schraubverbindungsmittel, a combination thereof or the like. Preferably, the mounting connection between the holding part 20 and the lighting component detachable. In the embodiment shown here is a screw with two screws 21 for mounting the holding part 20 on the lighting component.

The holding part 20 is for example as a holding frame 22 executed, which is a retaining recess 23 encloses. The retaining recess 23 passes through the holding part 20 completely and provides, so to speak, an opening in the holding part 20 dar. The contour of the retaining recess 23 is to the contour of the illuminant carrier 11 adjusted so that the illuminant carrier 11 does not protrude from the defined by the retaining recess clear space or clearance profile. Preferably, the top are 15 of the illuminant carrier 11 and / or the top 15 opposite back 24 of the illuminant carrier not through the holding part 20 covered. Especially the back 24 is completely freely accessible.

The holding part 20 has a holding device 27 on. The holding device 27 serves to the illuminant carrier 11 store or hold positively and / or non-positively. In the embodiment described here, the holding device 27 several clamping means 28 on to a clamping force on the illuminant carrier 11 exercise. The clamping means 28 are, for example, by resilient clamping tongues 29 of the holding part 20 educated. The clamping tongues 29 protrude from her with the holding part 20 connected end in through the retaining recess 23 defined clearance gauge into it. Within the clearance gauge of the retaining recess 23 are the clamping tongues 29 in the area of a clamping surface 30 curved and run starting from the clamping surface towards its free end. When holding the illuminant carrier 11 are the clamping surfaces 30 the clamping tongue 29 on an associated side edge 31 adjacent to the top 15 on the illuminant carrier 11 at.

As in particular from 3 and 4 it can be seen in the embodiment on three sides of the retaining recess 23 one or more clamping means 28 , for example Klemmzungen 29 , available. This allows clamping forces from different sides on the light source carrier 11 exercised and manufacturing tolerances of Light source carrier 11 be better balanced. In principle, it may be sufficient, a clamping means 28 on a single side of the retaining recess 23 to arrange and thus a single side edge 31 of the bulb 11 assigned. On the clamping means 28 opposite side may be the illuminant carrier 11 on the holding part or on supporting projections 32 be supported by the holding part.

The over the clamping means 28 generated clamping force is thus approximately parallel to the illuminant surface 12 and, according to the example, in the plane of the plate-shaped illuminant carrier 11 generated. The clamping means 28 let a movement of the illuminant carrier 11 in a direction perpendicular to the Leuchtmittefläche 12 , wherein this direction below as the pressing direction R referred to as.

The bulb holder 10 also has a cover 37 on. The cover part 37 is designed, for example ring-shaped and has a radiating aperture 38 , The emission opening is contoured circular in the embodiment. Deviating from this, the contour of the emission opening 38 also have a polygonal or other shape.

The radiating aperture 38 is on the holding part 20 or the illuminant carrier 11 associated side of the cover 37 by one or more pressure bodies 39 a pressing arrangement 40 limited. In the preferred embodiment described here is only a single annular closed pressure body 39 intended. Deviating from this, several could also be in the circumferential direction U regularly around the emission opening 38 distributed arranged Andrückkörper be present. The example annularly closed pressure body 39 has an approximately rectangular contour in cross section and can be in transition to the outer surface 41 of the cover part 37 be chilled.

For producing a releasable connection, preferably a releasable non-positive and / or positive connection, between the cover 37 and the holding part 20 serves a fastening device 45 the bulb holder 10 , About the fastening device 45 can in the embodiment without tools, the connection between the cover 37 and the holding part 20 be prepared and also solved again. For this purpose, a plurality of and preferably four attachment surfaces are preferably provided on the holding part 46 available. The number of attachment surfaces 46 may be chosen differently from this. According to example, each mounting surface 46 on a fastening projection 47 arranged. Every fastening projection 47 has a substantially in the direction of pressure R extending connecting section 48 and an adjoining, opposite the connecting portion 48 bent or angled end portion 49 on, at which the free end of the fastening projection 47 is available. The end section 49 also has the attachment surface 46 on. In the embodiment, the attachment surface 46 each on the cover 37 opposite side of the end portion 49 available.

As in particular in the 3 and 4 can be seen, are the fastening projections 47 on two opposite sides of the support frame 22 arranged in the region of the outer contour of the holding frame 22. The attachment surfaces 46 are outside the clearance of the retaining recess 23 arranged.

To the fastening device 45 (see in particular 7 ) also includes at least one counter-mounting surface 50 on the cover 37 , Every attachment surface 46 is a counter-fastening surface 50 assigned, so that, for example, four counter-mounting surfaces 50 on the cover 37 available. In 7 is schematically only a counter-fastening surface 50 illustrated in more detail. The other counter-fastening surfaces 50 are in a similar manner on the cover 37 provided and designed.

The counter-fastening surface 50 is at a radial projection 51 in a mounting recess 52 intended. The counter-fastening surface is located on the radial projection 51 on the holding part 20 opposite side. The counter-fastening surface 50 has a first surface section 50a which is inclined in the circumferential direction U. At the first surface section 50a closes a circumferentially tilt-free second surface section 50b at. On the second surface section 50b in the circumferential direction U opposite side is the mounting recess 52 to the holding part 20 through an insertion opening 53 open, through which the fastening projection 47 or its end section 49 in the mounting recess 52 can be introduced.

To make the connection, the cover is 37 on the illuminant carrier 11 and the holding part 20 put on, so that the illuminant surface 12 in the emission opening 38 located and through the annular Andrückkörper 39 limited and enclosed. The fastening projections grip 47 in the mounting recess 52 one. By a rotation of the cover 37 relative to the holding part 20 in the circumferential direction U reaches the end portion 49 each fastening projection 47 with its mounting surface 46 in contact with the associated counter-fastening surface 50 , First, it slides along the inclined first surface section 50a and then it comes into contact with the second surface section 50b , The detachable connection between the cover 37 and the holding part 20 is made by it. By turning the cover 37 in the opposite direction in the circumferential direction U, the releasable connection, via the fastening device 45 was prepared to be solved again.

The cover part 37 has at one of the pad 16 assigned location a connection recess 58 , When made attachment between the cover 37 and the holding part 20 grips the connection component and, for example, the plug component 17 in the connection recess 58 one. In the circumferential direction U is the connection recess 58 larger than the plug component 17 so that the connector component 17 the relative rotation between the cover 37 and the holding part 20 allows unhindered.

The relative rotation angle between the cover 37 and the holding part 20 is limited and is maximum 10 ° to 30 °. In the embodiment, the maximum angle of rotation is 15 °.

Based on 3 to 6 Below is the procedure for mounting the bulb holder 10 and explains their mode of operation or advantages.

First, as in 3 schematically illustrated the holding part 20 in the form of the support frame 22 attached to the associated lamp component (not shown), according to the example by means of screws 21 , Subsequently, the illuminant carrier 11 with the semiconductor illuminants 13 and the plug component 17 in the frame 22 or the retaining recess 23 used. He is through the holding device 27 or the clamping means 28 held strong. The on the illuminant carrier 11 For example, applied clamping force acts transversely to the pressing direction R approximately in the plane of the retaining recess 23 in two spatial directions ( 4 ).

Subsequently, as in 5 shown - the cover 37 from the light emission side of the semiconductor lamps 13 on top 15 of the illuminant carrier 11 put on so that the pressing projection 39 the illuminant surface 12 and the semiconductor illuminants 13 encloses annularly. In this Aufsetzbewegung attack the mounting projections 47 via the respective associated insertion opening 53 in each case a mounting recess 52 and are in the circumferential direction U adjacent to the counter-mounting surface 50 arranged. The plug component 17 engages in the connection recess 58 one.

Subsequently, the cover is 37 in the circumferential direction U to the pressing direction R or the emission opening 38 turned around, in the embodiment in a clockwise direction. This will get the attachment surfaces 46 the fastening projections 47 initially in contact with the inclined surface portion 50a the respective associated counter-fastening surface 50 , By this inclined surface portion is the cover 37 or the Andrückkörper 39 against the illuminant carrier 11 immediately adjacent to the semiconductor lights 13 pressed. It generates a pressing force in the pressing direction R on the illuminant carrier 11 , Since this in the Halteaussparung 23 located, the illuminant carrier can 11 thereby immediately adjacent to the illuminant surface 12 are pressed against the lamp component to which the support frame 22 is attached.

The luminaire component serves as a heat dissipation body and may be formed by a heat sink, or be connected to a heat sink.

The pressing force in the pressing direction R between the pressure body 39 and the illuminant carrier 11 increases as long as the mounting surfaces 46 along the respectively associated first surface section 50a slide. Once the mounting surfaces 46 at the respective in the circumferential direction U not inclined second surface portion 50b abut, the pressing force in the pressing direction R not further increased. In the embodiment, the relative rotation is terminated when the mounting surface 46 each fastening projection 47 completely on the respectively associated second surface section 50b the counter surface 50 is present (cf. 7 ). The prepared releasable connection attachment between the cover 37 and the holding part 20 is in 6 illustrates and represents the completion of the assembly.

Like, for example 6 it can be seen, a portion of the Andrückkörpers extends 39 when manufactured releasable attachment between the cover 37 and the holding part 20 between the illuminant surface 12 and the pad 16 , This will result in the electrical connection of plugs or wires in the area of the pad 16 accidental damage to the semiconductor lamps 13 avoided.

Due to the completely ring-shaped closed pressure body 39 can also in the circumferential direction U a very uniform good pressure force of the illuminant carrier 11 immediately adjacent to the semiconductor light elements 13 generated and the light source carrier 11 with his back 24 be pressed against the light component for heat dissipation. The pressing force is thus immediately adjacent to the at least one semiconductor illuminant 13 and with a distance A ( 7 ) to the edge of the illuminant carrier 11 on the illuminant carrier 11 exercised.

Optionally can on the cover 37 at least one component or a device for light conduction be provided. For example, at least one reflector 59 at least partially or as exemplified in 2 illustrated completely around the radiating aperture 38 be arranged around. The reflector 59 has in the embodiment one of the emission opening 38 away conically widening shape.

Alternatively or in addition to the at least one reflector 59 can the cover 37 a disc 60 having the emission opening 38 closes. The disk 60 is for those of the semiconductor light elements 13 radiated light wavelength at least partially transparent or permeable. The disk 60 may be made of glass or plastic. Optionally light-conducting surfaces or elements can be integrated in the pane 60.

At the in 1 illustrated embodiment, the disc 60 has a plurality of concentric light guide surfaces 61, so that the disc 60 has a lens effect. Alternatively or additionally, light-scattering particles or elements can also be integrated into the pane 60, so that the pane 60 virtually forms a diffusing pane. The disk 60 may be configured in any known manner for deflecting and / or refracting and / or focusing and / or scattering the emitted light. Also colored filters or the like may identify the disc 60. In addition or as an alternative to the disc, a lens may also be present. Any combination of serving for light conduction devices or components may be on the cover 37 be provided.

In the embodiments shown here, the cover member 37 Auxiliary devices to the relative rotation relative to the holding part 20 to simplify. In the embodiments according to the 2 . 5 . 6 and 7 this auxiliary device is by two relative to the emission opening 38 diametrically opposed handle parts 65 formed by the outer surface 41 of the cover part 37 protrude. The handle parts 65 For example, have a cuboid shape, but can also have any other easily hand-to-grasp shape.

Alternative to the handle parts 65 are in the embodiment after 1 diametrically opposite relative to the emission opening 38 two engagement recesses 66 in the cover 38 introduced in the emission of the light or from the outer surface 41 are accessible. The engagement recesses 66 can be sufficiently large to insert the fingers of a hand and the cover 37 to be able to turn. Alternatively, it is also possible, the engagement recesses 66 form for insertion of a rotary tool, with the aid of the cover 37 relative to the holding part 20 can be rotated in the circumferential direction U.

All embodiments of the lamp holder 10 can handle parts 65 and / or engagement recesses 66 be executed.

That on the basis of 3 to 6 described method for mounting the bulb holder can be performed in reverse order to their disassembly. The holding part 20 can remain attached to the lighting component, if only the cover 37 is removed to the light source carrier 11 with the semiconductor lights 13 exchange. After inserting a replacement illuminant carrier, the cover can 37 as described again on the holding part 20 be attached.
