Light Profile Tubing The present invention relates to a light profile tube having light sources mounted in a longitudinal direction and a profile cross section substantially constant along the longitudinal direction. Such light tubes are be known ^¬ from the prior art. For example, discloses the European Offenle ^¬ supply EP 1564 914 Al a light chain or a light tube with attached along the chain or of the tube light emitting elements for emitting optical communications signals along the chain. It can be one

Chain, for example via a corresponding object ge ^¬ depends (see, for. Example, Figure 51 or Figure 54 of the above-mentioned EP publication) or along a line shifted (see, for. Example, figure 62 and 63 of the aforementioned EP- Font) .

It is an object of the present invention to achieve a comparison with the prior art improved and / or simplified Hal ^¬ sion of light elements in the context of a light tube.

This object is achieved by a light profile hose with the features of the present patent claim 1. Such a light profile hose comprises light sources mounted in a longitudinal direction and has a profile cross section which is substantially constant along the longitudinal direction. Along the profile cross-section or in the profile cross-sectional plane, the light profile hose loading a fastening portion for mounting the light profile hose, egg ^¬ NEN lamps portion for receiving the lamps and a connecting portion for connecting the fastening Section and bulb section on. Furthermore, the illuminant section comprises a cavity section closed in the profile cross-section or in the profile cross-sectional plane for receiving the illuminant, wherein the cavity section is at least partially optically transparent such that light can escape from the illuminant from the light ^profile tube.

By the attachment portion and the thus connected via the connection portion of the illuminant portion of

Lichtprofilschlauchs it is possible, the light bulbs verein ^¬ facht within the light profile hose over the fastening ^¬ supply section, for example, to an object, a wall, a rail or the like to attach or to fix him. In this way, for example, an at least case ^¬ compared to the prior art simpler attachment of the light profile tube is achieved. Furthermore, the

Illuminant protected by the closed cavity section from environmental influences, which allows easier handling of the light profile hose, especially in industrial, ver ^¬ dirty or outdoor areas.

Illuminants can be, for example, electrically operated illuminants such as light bulbs, light-emitting diodes or comparable light-emitting elements (eg semiconductor LEDs, OLEDs or comparable area radiators). Furthermore, lamps may also be luminescent, phosphorescent or chemically-excited luminous means or include such light ^¬ medium.

The lamps can, for example, on a support, for. B. alone or together with other bulbs, be arranged. Such a carrier may be formed, for example, as a circuit board or printed circuit board and, for example, continue to comprise electrical connection lines or possibly also one or more electrical control circuits or AnSteuerelemente for the one or more bulbs. The carrier and / or The board may, for example, continue to be flexible or rigid.

Furthermore, the lighting means for the transmission of optical see data signals, for example according to a so-called VLC standard (VLC: Visual Light Communication, standard development eg within the "IEEE 802.15 Visible Light Communication Interest Group") or comparable communication or data protocols be furnished and / or trained.

As substantially a profile cross-section is constant referred to in ^¬ game as if it has upon receipt of the constant basic forms, for example, fabrication requires minor variations in the detailed design of, for example, a substantially constant profile cross section constant basic shapes with smaller measure deviations and / or smaller shape Be deviations. In particular, the profile cross section may also be constant along the longitudinal direction.

Furthermore, the profile cross-section may also have short modified cross-sections at regular or irregular intervals (for example at a distance of a few millimeters, centimeters, tens of centimeters or even meters), in order to obtain, for example, facilitate laying or handling of the light profile tubing (e.g., to facilitate curling, bending or twisting of the light profile tubing or insertion into a splint or other fixation device) or to allow access to the illuminant area. Such altered cross sections may e.g. be formed as cuts, notches or grooves in the attachment area and openings and / or cuts / notches / grooves in the bulb area.

The profile cross-sectional plane may, for example, be perpendicular or substantially perpendicular to the longitudinal direction of the

Light profile hose lie. The fact that the cavity section is closed in the profile cross-sectional direction can be provided, for example, such that the cavity section in profile cross-section direction substantially longitudinal areas of the light profile tube, in more than 50% and / or in more than 90% of the longitudinal extent of the

Profile hose is closed. It may be further example ^¬ be provided that the light-emitting center portion is accessible from the outside in egg ^¬ nem or both end portions of the light profile hose, for example, electrical supply and / or discharge or a supply and / or removal of chemical lamps or inert gases to enable. Furthermore, a ^¬ zelne openings of the luminous center portion can be easily seen to the outside ^¬ also in the longitudinal course of the light profile tube to allow, for example, also electrical supply and / or derivatives or corresponding supply or removal of chemical substances. In particular may be further provided that the light-emitting center portion of the Lichtpro ^¬ filschlauchs openings to the outside only in the end regions of the light tube profile or one of the end portions of the light profile tube. The said openings in the light ^¬ telabschnitt can, for example, for repair

and / or the replacement of bulbs be provided and set up. The optically transparent section of the luminous ^¬ telabschnitts may be configured such that it is designed to be transparent to the complete visible, infrared and / or ultraviolet Spe ^¬ rum or only for individual spectral ranges of said spectra. Furthermore, the transparent region of the luminous means section can be designed geometrically in such a way that an opening angle defined perpendicularly to the longitudinal direction results for a light emission by the luminous means located in the luminous means section. Here, for example, an opening angle of less than 30 degrees for a substantially dishes ^¬ te radiation or an opening angle of beispielswei- greater than 60 degrees for substantially all-round radiation.

In an advantageous embodiment, the optically transparent region of the luminous means section may comprise one or more lens elements. Furthermore, the optically transparent region of the luminous means section may be formed at least from section- ^wise or partially lens-shaped. The lens elements or lens sections or areas may, for example, be designed to be essentially round, oblong or essentially unchanged along the longitudinal direction. In this way, depending on the selection or arrangement of the lighting means or possible applications of the light profile tube, punctiform foci can result in substantially round lens elements or lenticular regions.

When in the longitudinal direction substantially homogeneous lens elements or lens-shaped areas result, depending on an arrangement of and severity of lamps or a plurality of longitudinally elongated ^¬ Lichtfoki or a line-shaped focus along the longitudinal direction of the light profile tube. In this way, an improved emission and bundling of the emitted light allows better use of catcher provided on Lichtemp- and / or reflectors or other optical elements he ^¬ rich and so the emitted light in such applicatio ^¬ gen. For example, a lens-shaped optically transparent region can be designed in such a way that a corresponding edge region of the cavity section is formed from optically transparent material which is lenticular in the profile cross-sectional direction and homogeneous in the longitudinal direction.

Furthermore, the bulbs can be electrically operated

Illuminants include or be designed as electrically operated lighting ^¬ medium, wherein it can further be provided that a power supply for the electrically operated NEN bulb is also included in the light profile tube. In this case, the lamps can be connected in series, for example, or connected in parallel or can be supplied with energy independently of each other. Furthermore, a mixture of Beschaltungsmöglichkeiten can be provided. The power supply may, for example, a wire cable or also, for example in the luminescent center portion comprise up broke ^¬ te metal traces or include lines and / or sheets of other electrically conductive materials or have. The supply of the electrical lines or the electrical energy can be effected for example via openings in the one or more end regions of the light profile tube.

Furthermore, it can be provided that each lighting means is assigned an electronic control circuit for controlling the light emission of the lighting means. Furthermore vorgese ^¬ hen may be that the control circuit is also located in the luminescent center portion of the light profile tube. In addition, it can furthermore be provided that the drive circuit is provided in spatial proximity to the lighting means in the light-emitting means section of the light profile hose. It can be assigned its own drive circuit each light ^¬ medium. Furthermore, a drive circuit may be provided for a plurality of light sources or else a drive circuit for all

Illuminant of the light profile tube.

A drive circuit may comprise, for example, any type of electronic circuit, for example simple switching elements such as a transistor or a diode, one or more integrated circuits or even a complex electronic circuit. It can further be provided that the lighting means or one, several or all of the lighting means are mounted on a common carrier with the drive circuit, for example a circuit board, are mounted in particular in spatial proximity to the drive circuit. The carrier or the board may be, for example, forms ^¬ flexibly, which, for example, turn the light profile hose easier to handle, since the bending or twisting is simplified or the risk of damage, for example, when bending or twisting the hose is reduced. In addition, the illuminant portion may also include at least Since ^¬ tenleitung include for transferring to be emitted by the illuminant optical signals. For example, it may be provided that a power supply is provided for the lighting means and additionally a data line, via which the signals to be transmitted are transmitted, which are then modulated onto the emitted light signal, for example using the known methods. Here, the data line can be performed for example for the aforementioned Ansteu ^¬ erschaltung for one or more of the lighting means, or even directly to the bulbs. Of course, data transmission and power supply can also take place via the same conduction paths (comparable, for example, with the so-called "power over Ethernet" or "powerline" method). The emission of the optical signals can be carried out, for example, according to the so-called VLC standard 8 (Visual Light Communication).

In an advantageous embodiment, the light profile hose can continue to encompass light sensors in the light source section. Such light sensors may be, for example, electrically operated light sensors such as diode detectors made of semiconductor material or organic semiconductor material or similar materials or other optical sensors. In this way, not only optical signals can be transmitted but also received by means of the light profile hose.

In a further advantageous embodiment, the light profile hose can comprise, for example, both electrically operated light sources and electrically operated light sensors in the light source section. In this case, the Leuchtmit ^¬ telabschnitt of the profile tube then continue to provide funds for a power supply of the lighting means and the light sensors and means for deriving sensor signals include. Moreover, the luminous center section may also include a Datenlei ^¬ processing of transmitting through the lamps data to be transmitted to the light sources. The mentioned

Lines may be, for example electrical lines from Me ^¬ talldrähten or of other electrically conductive materials. Furthermore, the corresponding means for energy supply, data line and discharge can also consist of a carrier material or even directly the light profile tube material on ^¬ brought or attached line layers or include such.

Furthermore, the means for a power supply may, for example, also comprise additional drive circuits or power supply circuits.

The means for deriving the sensor signals can be ent ^¬ speaking formed of means for the energy supply and, for example, also a corresponding ER that can be triggered and / or evaluation circuit for the respective sensors.

For the derivation of the signals of one or more or all of the sensors of the light profile tube, it is also possible, for example, for radio means (eg according to the WLAN standard or the RFID standard) to be provided.

In an advantageous embodiment, each light source can be associated with exactly one light sensor, wherein the light source and the light sensors can continue to be designed, for example, as semiconductor light sources and semiconductor light sensors. The semiconductor materials can Liehe "classical" semiconductors such as silicon, germanium, gallium arsenide, or similarity, or as organic or other semiconductor materials ^¬ rials be formed or include such. In a further advantageous embodiment are each a light source and light sensor on a common support, such as a circuit board. In addition, it is also possible to provide a corresponding activation circuit for the luminous means and / or for the light sensor on the support. For example, the carrier may be formed as a printed circuit board or PCB with attached thereon lamps and Sen ^¬ sor and the actuation and evaluation circuits for light sensor and light sources.

The attachment portion of the light profile tube can be set up and formed in ^¬ example, for attachment of the light profile hose to an object, a building part such as a wall or a ceiling or in particular for attachment to a rail or other elongate support. In particular, the buildin ^¬ actuating portion may be configured such that it can be mounted in or on a rail by pushing and / or pulling, in particular without use of tools can be attached in such a manner. For this purpose, the fastening portion can at ^¬ play one or a plurality of at least partially comprise in the cross-sectional plane extending projections which cooperate with respective rail elements and / or -Vorsprüngen for fixing the light profile tube.

Furthermore, the connecting ^portion example ^¬ include an elastically deformable material or consist of such material. In addition, the connecting portion may comprise a damping element. As elastic-deformable material can, for example Gum ^¬ mi, a rubber-like substance, an elastic plastic, an elastic metal, rubber and / or similar Materia ^¬ lien be used.

As a damping element, for example, a shock or vibration-absorbing or -reducing material or element may be used, for example a spring element, a Dämp ^¬ tion element and / or a damped spring element.

Further advantageous embodiment possibilities can be found in the subclaims.
