Description

The invention relates to a lamp with a housing, with an electrical connection device and with a lamp carrier, according to the preamble of claim 1 and a method for producing a lamp having a lamp carrier and a lamp carrier suitable for a lamp.

A generic lamp can be the result of a lamp being converted from a fluorescent lamp, in particular a fluorescent tube, to an LED lamp. Such lights can have the advantage, on the one hand, of achieving the efficiency associated with an LED light source and, on the other hand, by continuing to use elements, such as the housing of an already existing light source, in particular manufactured as a light with a fluorescent light source, in particular on a component such as a ceiling or wall of a building mounted light to be less expensive to manufacture and install than a completely new LED light. Disposal costs can also be saved. For example, a generic lamp from the DE 20 2017 103 992 U1 famous.

Several problems can arise with generic lights. If the existing ballasts suitable for fluorescent lamps (e.g. magnetic ballasts or electronic ballasts) are to continue to be used, these may represent a possible source of error, and depending on the type of ballast suitable for fluorescent lamps and the LED lamp, prevent a successful conversion or replacement. lead to efficiency losses.

If the ballasts that are suitable for a fluorescent lamp are no longer to be used, the process for producing a lamp of this type is often complex, since extensive changes to the electrical supply lines are usually required.

In addition, there can be disadvantages in terms of electrical protection and light distribution, as well as in terms of the effort required to replace a defective LED light source with a new one.

The present invention is therefore based on the object of providing a lamp with a housing, with an electrical connection device and with a light source carrier which at least partially eliminates the described disadvantages of lamps of the generic type.

In addition, the invention is based on the object of providing a method for producing a lamp that at least partially eliminates the disadvantages of generic methods.

In addition, the invention is based on the object of providing an improved illuminant carrier suitable for a lamp or for producing a lamp.

As a solution to one of the objects on which the invention is based, the invention proposes a lamp with the features according to claim 1 .

The lamp according to the invention comprises a housing with an electrical connection device. The lamp according to the invention also includes a light source carrier which is preferably arranged on the housing, in particular fastened, in particular fastened directly. The illuminant carrier comprises an elongate support body. The illuminant carrier also includes an electrical connection device, by means of which it is connected to the electrical connection device of the lamp.

The connection device of the illuminant carrier and the connection device of the lamp, which is preferably fixed to the housing independently of the illuminant carrier, are designed to correspond to one another, so that the interaction of the connection device and connection device means that the illuminant carrier is connected to a supply network. Generally preferably, the connecting device can include supply lines, a plug-in device and/or a connecting terminal unit. Correspondingly, the connecting device can comprise supply lines, a plug-in device and/or a connecting terminal unit. In one embodiment, the connection device comprises a plug-in device and the connection device comprises a plug-in device complementary to the plug-in device. The connection device particularly preferably comprises supply lines, in particular supply lines connected to a supply network, such as building lines, which are connected to a connection terminal unit of the connection device, or the connection device comprises supply lines which are connected to a connection terminal unit of the connection device. This is based on the intended operating state of the lamp. Two brackets lying opposite one another in the longitudinal direction are provided on the elongate supporting body. The holders thus have sides that point towards one another in the longitudinal direction, between which a receiving area for receiving an LED light source, in particular an LED retrofit fluorescent tube, in the longitudinal direction between the halves ments is formed. At least one holder has a socket with an electrical contact or with electrical contacts for an LED light source.

The light fixture may be the result of upgrading a fluorescent light fixture from a fluorescent light fixture to an LED light fixture.

The lamp according to the invention has several advantages. The at least one socket makes it easy to replace a defective LED light source with a new one. In addition, the LED lamps that are readily available on the market and work together with sockets can be used here. The lamp according to the invention also makes it possible, when converting a lamp from a fluorescent lamp to an LED lamp, to stop using any existing ballasts that are suitable for a fluorescent lamp without extensively changing the electrical supply lines and therefore avoids the cost of retrofitting sources of error and efficiency losses often associated with these ballasts. The electrical connection device of the illuminant support also makes it possible to avoid or reduce the changes to the electrical supply lines that have to be carried out at the intended place of use of the lamp and often overhead during a conversion. For example, to implement the lamp according to the invention on the basis of a fluorescent lamp lamp, the fluorescent lamp and the fluorescent lamp sockets can be removed in a first step and the fluorescent lamp ballast can be separated from the connection device and in a second step the lamp support be attached to the housing and connected to the connection device with its connection device.

1 shows a perspective representation of an exemplary embodiment of a lamp 1 according to the invention. The reflector and the anti-glare grid have been omitted in this figure for the sake of simpler representation.

The lamp 1 has a box-shaped housing 2 with a base plate 35 in which an electrical connection device 3 and a light source carrier 4 are arranged. The lamp 1 has a e.g 8th shown reflector 25 and an anti-glare grid 31 on. The illuminant carrier 4 includes an electrical connection device 21, which is formed by supply lines 33 in the exemplary embodiment shown. By means of this electrical connecting device 21, the illuminant support 4 is electrically connected to the connecting device 3, which in the exemplary embodiment shown comprises supply lines 5 and a connecting terminal unit 6 connected to these supply lines; more precisely, the supply lines 33 of the connecting device 21 of the illuminant support 4 are in the terminals of the connecting terminal unit 6 of the connecting device 3 clamped. The electrical connection device 3 and thus also the electrical connection device 21 is connected to a 230 V voltage.

The supply lines 5, 33 each comprise exactly three lines, namely phase 37, neutral conductor 38 and protective conductor 39.

The illuminant carrier 4 includes an elongated support body 18, which can be made of aluminum. At this two opposite brackets 7 are arranged. These each include a socket 19. The brackets 7 hold an LED illuminant 15. More precisely, the sockets 19 have electrical contacts 20 and establish a detachable mechanical and electrical connection between the LED illuminant 18 and the sockets 19.

The lamp 1 is the result of a conversion of a fluorescent lamp lamp 30 from a fluorescent lamp to an LED lamp 15. The housing 2, the connection device 3, the reflector 25 and the anti-glare grid 31 are unchanged from the fluorescent lamp Luminaire 30 taken over.

The LED illuminant 15 is designed as a tubular LED retrofit illuminant 32 and has two pin contacts 16 at both of its ends, as is shown in FIG 2 shown schematically for one end.

Like this particularly well in the 3 and 4 can be seen, the elongated support body 18 has a region with a U-shaped cross Section 11 and is completely U-shaped in the embodiment shown.

The brackets 7 are arranged on the side of the elongate supporting body 18 opposite the opening 12 of the U-shaped cross section. As the 4 , 5 and 6 show, the elongate supporting body 18 has two holder mounting recesses 17 and a bore 34 for the supply lines 33 of the electrical connection device 21.

7 shows part of a lamp according to the invention without anti-glare grid and without lamps, but with reflector 25. This comes unchanged from the fluorescent lamp lamp 30 and extends in the form of a trough over the entire length of the elongated supporting body 18 and accommodates it.

7 also shows the connection device 3 with the supply lines 5 and the connection terminal unit 6 as well as the connection device 21 connected to it with its supply lines 33 in more detail.

8th shows part of a lamp according to the invention 1 , with the reflector 25 taken unchanged from the fluorescent light source lamp and with the anti-glare grid 31 taken unchanged from the fluorescent light source lamp 30.

8th shows the interaction of the LED illuminant 15 with the reflector 25 and the anti-glare grid 31. The illuminant carrier 4 and in particular its elongated supporting body 18 is designed in such a way that a position of the sockets 7 relative to the optical properties of the LED illuminant 15 is optimized the housing 2 and the reflector 25 results. For this purpose, the U-shaped cross section 11 in the exemplary embodiment shown has a height 26 running in the direction of its legs, ie in the vertical Z, which can be approximately 20 mm. The U-shaped cross-section has a width 27 running transversely to the direction of its legs, ie in transverse line Y, which is approximately 35 mm.

The distance 10 of the sockets 19 to the base plate 35 of the housing 2 after the mechanical attachment of the lamp carrier 4 to the housing 2 is therefore optimized for the LED lamp and its interaction with the lamp, for example with the reflector and anti-glare grid adopted. 8th also shows that the lamp 1 has an operating device 23 for converting the electrical supply present at the connection device 21 into an electrical supply suitable for operating the light sources 24 of the LED illuminant 15 and that this operating device 23 is exclusively connected to an assembly 22 comprising the illuminant carrier 4 and the LED illuminant 15, namely in the LED illuminant 15, is provided.

9 serves to illustrate the positioning and attachment of the illuminant carrier 4 in the housing 2. The reflector 25 is in 9 only shown in half and dashed, the LED illuminant and the anti-glare grid are omitted.

In synopsis with 12 leaves 9 the fastening device 8 of the illuminant carrier 4 designed as a quick fastening device for the mechanical fastening of the illuminant carrier 4 to the housing 2 can be seen. It fastens the illuminant support 4 to the housing 2 in such a way that the free ends of the legs of the U-shape of its elongated supporting body 18 at least almost bear against the base plate 35 of the housing.

The fastening device 8 comprises two disc-shaped magnets 9. Each magnet 9 is fastened to the illuminant carrier 4 with a magnet fastening screw 36, which extends through the elongated supporting body 18 and runs parallel to the legs of the U-shaped cross section 11.

the 10 and 11 show the illuminant carrier 4 suitable for a lamp 1 or for the production of a lamp 1. The illuminant carrier 4 is a component separate from the housing 2. In the 11 The electrical supply to both holders 7 that can be seen makes it clear that both of these holders 7 are designed as holders 19 .

12 shows one of the two quick fastening devices each having a magnet 9 in more detail and the overcurrent protection device 13 designed as a safety fuse 14, more precisely a fine-wire fuse, which is arranged outside of the LED illuminant 15 and can be replaced separately from it. It also shows the electrical connection of the protective conductor 39 by means of the magnet fastening screw 36 to the elongated supporting body 18 of the lamp holder 4 and the magnet 9.

13 serves to illustrate an exemplary embodiment of the method according to the invention. It shows a fluorescent light source lamp 30 in which the anti-glare grid 31 and the reflector 25 have already been dismantled and the fluorescent light source has already been removed.

The fluorescent lamp lamp 30 includes a housing 2, an electrical connection device 3, fluorescent lamp sockets 28, suitable for fluorescent lamps, of which in 13 only one is shown, one not in 13 shown fluorescent lamp ballast connected to the electrical connection device 3 (or can be connected).

The sockets 28, suitable for fluorescent lamps, are removed.

Subsequently, the illuminant carrier 4 described above is mechanically fastened to the housing 2 by means of the fastening device 8 described above, comprising an elongated supporting body 18 , an electrical connection device 21 and two opposite brackets 7 .

In the exemplary embodiment shown, both holders 7 each include a holder 19 which is similar to the removed fluorescent lamp holders 28 and the distance between the holders of the lamp carrier corresponds to the distance between the fluorescent lamp holders 28 which have been removed. match.

A synopsis of 13 with 9 shows that the distance 10 of the sockets 19 of the illuminant support 4 to the housing 2 - more precisely to the base plate 35 of the housing 2 - is greater than the distance 29 of the fluorescent illuminant after the mechanical attachment of the illuminant support 4 to the housing 2 Sockets 28, which have been removed, to the housing 2 - more precisely to the base plate 35 of the housing 2 - before their removal.

The illuminant carrier 4 is then connected to the electrical connection device 3 by means of the electrical connection device 21 independently of the fluorescent lamp ballast.

The reflector 25 and the anti-glare grid 31 are then mounted on the lamp 1 again. Both the reflector 25 and the anti-glare grid 31 are illuminated directly by the LED illuminant.
