Description

Technical area

The present invention relates to a lamp with a tubular lamp body, wherein in the tubular lamp body at least a first and a second line bundle or at least a first and a second line are arranged. It also relates to a method for producing such a lamp and a spacer element.

State of the art

It is a known problem that in lamps to electromagnetic interference between so-called lamp lines on the one hand and network and control lines on the other hand can come. In this case, lamp leads provide the electrical connection between an electronic ballast and at least one light source. On this connection, the energy for operating the light source is transmitted from the electronic ballast to the light source. For transmission, a signal of high alternating or constant frequency is often selected. In one embodiment, it is a square wave signal with a frequency between 10 and 100 kHz.

Power cables run between a power supply and the electronic ballast. Control lines transmit control signals for communication with sensors, other lights or central control units. Depending on the arrangement of the electronic ballast in the lamp, it may happen that lamp lines on the one hand and network and control lines on the other hand at least partially parallel sections. In particular with through-wiring to other luminaires, lamp cables as well as mains and control cables even run predominantly in parallel.

The fields around the lamp lines are so strong that they negatively influence the EMC behavior of the lamp by coupling mechanisms between lamp lines on the one hand and network and control lines on the other hand. The lamp line acts as a transmitter and the power and control lines as a receiver. Through this coupling can be bridged in an electronic ballast usually built-filter. In this way electromagnetic interference can be fed into widely branched networks and disturb other resources.

To avoid this electromagnetic interference lamp lines on the one hand and network and control lines on the other hand in the luminaire body as far as possible spatially separated from each other to keep capacitive and inductive couplings as low as possible. In the prior art brackets, bent metal tabs or adhesive dots are used for this purpose.

However, these measures are not applicable in the case of lights whose body consists of a closed extruded profile, since the desired fixation points are not accessible.

Presentation of the invention

Therefore, the object of the present invention is to provide measures so that the coupling of EMC disturbances of lamp lines on network and control lines can be largely prevented even with lights with a tubular lamp body.

This object is achieved by a luminaire with the features of claim 1, by a spacer element with the features of claim 16 and by a method having the features of claim 18.

The present invention is based on the finding that in the case of luminaires with a tubular luminaire body, the wiring is pushed into the luminaire body. Since a subsequent fixation of the corresponding lines in the luminaire body is not possible, a spacer device is provided, with which the wiring is prefabricated outside of the lamp body. This results in a module comprising the lines and the spacer device. This can then be inserted into the lamp body. In this case, the spacer device is designed to fix the first and the second line or the first and the second line bundle at least in regions at a predeterminable distance from one another. In this way, a maximum distance between the lamp line on the one hand and network and control lines on the other hand over a maximum line length can be forced away. This reduces the coupling of electromagnetic interference from the lamp line to the power and control lines. The invention is preferably in luminaires with a tubular Lamp body applicable, but can also be used in other types of luminaire housing.

The spacer device stabilizes independently in the lamp and is preferably made of electromagnetically non-effective material.

Instead of a single line, it may also be a group of lines, so that these terms are to be regarded as a synonym in the following.

Pre-assembly can be done with or without electronic ballast and with or without any filters.

In a preferred embodiment, the lamp body has a longitudinal axis and a transverse axis, wherein the spacer device also has a longitudinal axis and a transverse axis, wherein the longitudinal axis of the spacer device in the arrangement of the spacer device in the lamp body is parallel to the longitudinal axis of the lamp body, wherein the transverse axis of the spacer device when arranged the spacer device in the lamp body runs parallel to the transverse axis of the lamp body. In this case, the spacer device comprises at least one spacer element whose longitudinal axis and transverse axis extend parallel to those of the spacer device.

In this case, the at least one spacer element preferably comprises in the transverse direction a first receiving device for the first line bundle or the first line arranged at its first end and a second receiving device for the second arranged at its second end Line bundle or the second line. In this way, it is possible to keep the first and the second line or the first and the second line bundle at a predeterminable distance from each other by appropriate dimensioning of the spacer element.

The at least one spacer element has at least one transverse element which extends in the transverse direction, wherein the at least one transverse element is rigid, in particular torsionally rigid, wherein the at least one transverse element is coupled between the first and the second receiving device. By means of such a design of the spacer, a predeterminable distance between the first and the second line or the first and the second line bundle can be set reliably.

Preferably, the first and / or the second receiving device between the at least one transverse element and the lamp body is arranged. This means that the receiving device (s) on the inside of the lamp body abut. As a result, the elasticity of the lines and / or the bundle of cables and / or the receiving device (s) can be exploited in order to be able to simply insert the thus prefabricated module into the luminaire body in order to ensure a reliable hold of the module in the luminaire body.

Alternatively, the at least one transverse element may be in contact with the lamp body, wherein the first and / or the second receiving device laterally on the at least one transverse element is arranged. This makes it possible to realize a particularly stable arrangement of the module in the luminaire body, which guarantees reliable positioning within the luminaire body even when the luminaire shakes.

According to a preferred embodiment, the first and / or the second receiving device comprises a cable tie for receiving the respective line or the respective trunk group. This makes it possible to realize a fixation of the respective line or of the respective line bundle on the spacer element in a particularly simple manner with low weight. By using a cable tie, the invention can be used universally, regardless of the number of lines that are present in a trunk group depending on the light. In this way, it is ensured that the wires or bundles of wires are inserted when the module is inserted, i. the pre-assembled wiring, do not slip in their receiving devices.

Alternatively, the first and / or the second receiving device may also include a flexible spiral for receiving the respective line or the respective trunk group. In this case, the respective line or the respective trunk group is introduced into the spiral, which is particularly suitable due to their flexibility, to exclude line breaks or damage to the cable insulation. Both when using cable ties and the use of flexible spirals, it is ensured that the pre-assembled wiring slides well when inserted into the luminaire body and does not tilt.

According to a preferred development, the at least one transverse element comprises at least one first coupling device in the longitudinal direction. In this way, a plurality of transverse elements can be coupled together, so that even with lines or cable bundles, which are not made of solid wire, but of strands, an unrestricted application of the present invention is made possible. While the stability in the longitudinal direction can be ensured by the line or the trunk group itself for cables or bundles of solid wire, it is particularly advantageous for lines or bundles of strands to prevent the prefabricated wiring from being pushed together when inserted into the lamp body, to use spacer elements , which are supported in the longitudinal direction to each other.

In this context, it is further preferred if the at least one spacer element further comprises at least one intermediate element which comprises at least one second coupling device, wherein the second coupling device is designed to cooperate with the first coupling device to couple two transverse elements in the longitudinal direction. Due to the length of the intermediate element, therefore, the stiffness of the lines or trunk groups can be taken into account. The stiffer the line or the bundle of wires, the longer the intermediate element can be carried out, which can reduce the number of spacers required.

It has proved to be particularly advantageous if the at least one transverse element and / or the at least one Intermediate element for varying its length comprise / comprises a telescopic device. Thereby, the universal applicability of the present invention is increased, since regardless of the maximum diameter of the lamp body or the length of the lamp body, a pre-assembled wiring can be adapted thereto. In particular, reduces the storage costs, since only a few different cross members or intermediate elements must be kept in stock.

In this case, the telescopic device may comprise at least a first telescopic element, a second telescopic element and a locking device, wherein the locking device is designed to fix the first telescopic element, in particular reversibly, in a predetermined position relative to the second telescopic element. Should it turn out in a prefabricated wiring after introduction into the lamp body that the maintenance of the wiring in the lamp body is not yet satisfactory, it can be achieved later by an optimal adaptation of the transverse elements or intermediate elements to the predetermined shape of the lamp body.

As mentioned, the first line preferably represents a network and / or control line or the first group of lines comprises a network and / or control line. The second line represents in particular a lamp line or the second line bundle comprises at least one lamp line.

The cross section of the lamp body can be round, angular, in particular square or hexagonal, but also oval. It is particularly preferably made of an extruded profile.

Further preferred embodiments emerge from the subclaims.

The preferred embodiments presented with reference to the luminaire according to the invention and their advantages apply correspondingly, as far as applicable, to the spacer element according to the invention and to the method according to the invention.
