Description

The present invention relates to a signal lamp for vehicles, comprising a housing and a number of light sources and at least one detachable from the housing transparent lens and an elongated Lichtleitelement with at least one light guide, in which by means of light emitting diodes light at the front ends of the light guide can be coupled, wherein the light guide extends over substantially an entire width of the signal light and the light-emitting diode is arranged on a printed circuit board, according to the preamble of claim 1.

Generic signal lights are often arranged at the rear of towed vehicles, which may be, for example, trailers of trucks, which is only by way of example and not conclusively seen. The signal lamp according to the invention explained in more detail below is intended for use on both towed vehicles and motor vehicles in general.

Such signal lights fulfill several lighting functions, such as tail light and / or brake light and / or flashing light and / or reversing lights and / or fog tail light. In addition, it is necessary in some vehicles to provide side marker or side marker lights. Of the light functions mentioned, that of the tail light is that which is dominant in terms of the time during which the light function is used. If the tail light fails, the vehicle ahead can only be made more difficult by the subsequent traffic in the dark.

The experience of the practice shows that in everyday operation defective signal lights on, for example, drawn vehicles little attention. So it may well happen in rough everyday use of such a vehicle that the signal light is damaged such that the lens breaks or breaks and the underlying bulb in the form of a light bulb, which performs the tail light function is also damaged and thus no longer lit. Even with a signal light provided with a light guide as a light distribution element, the lens can be damaged with the underlying light guide.

Known signal lights are designed as integrated units in such a way that damage to the signal light also leads only to the extent of a light function that the complete signal light must be replaced, which leads to high costs and therefore the replacement often fails.

Based on DE 41 29 094 A1 is a signal lamp for motor vehicles has become known, which is equipped with light guides into which light can be coupled via light emitting diodes and the coupled light is emitted over the longitudinal extent of the light guide. The known signal light is designed such that the light-emitting diodes are arranged on a printed circuit board, which is arranged on an inner surface of the outer wall of the housing of the signal light. If the housing of the known signal light is damaged, the circuit board is exposed and in everyday use of the vehicle forcibly penetrates moisture into the housing, which ultimately leads to failure of the entire unprotected PCB electronics and thus the total failure of the known signal light.

In addition, shows 2 This document that the individual optical fibers are coupled to each other via fasteners "B", which are mechanically separated from the circuit board "LP" and therefore independent of the attachment of the circuit board in the housing of the known signal light. This in turn means that the light guide and the circuit board must be mounted separately from each other in the housing, which increases the installation effort and thus the installation costs. A simple assembly and a simple replacement of damaged components is therefore not provided in this known signal light.

Based on DE 196 52 159 A1 is a lighting device for vehicles has become known, which has a light guide to form a marker light, wherein the light guide extends at least over part of the outline of the illumination device near the edge of the lens, so in an area that experience has shown to damage the lighting device often affected is pulled so that the light function of the position light is no longer given. In this known lighting device, light is coupled in via a light source arranged at a distance from the light source, so in the assembly of the known lighting device separate components in the form of the light source and the light guide must again be mounted in the housing of the known lighting device. A, a simple replacement of damaged components enabling modular design is therefore also not given in the known lighting device.

Proceeding from this, the present invention, the object of the invention, the signal lamp in such a way that a simple replacement of the light guide in the event of damage is possible and in such a case the local damage does not have to be replaced by the complete signal light. Also, the signal lamp according to the invention is intended to provide the light function provided by the light guide in case of damage to the lens nor such damage to the lens do not lead to total failure of the signal light.

To solve this problem, the invention has the features specified in claim 1. Advantageous embodiments thereof are described in the further claims.

The invention provides a signal light for vehicles, with a housing and a number of light sources and at least one detachable from the housing transparent lens and an elongated Lichtleitelement with at least one optical fiber, in which by means of at least one associated LED light at the front end of the light guide can be coupled wherein the optical fiber extends over substantially an entire width of the signal lamp extension and the light-emitting diode is arranged on a circuit board and at the front end of the at least one light guide, a circuit board receiving terminal housing is arranged.

Thus, the invention provides a signal lamp, in which the circuit board is arranged with the at least one light emitting diode at the front end of the at least one light guide together with the terminal housing and thus a necessary for functioning of the light guide module components and / or components uniting module is created In the event of damage to the signal light and the fiber optic module can be easily replaced without the signal light must be completely replaced. For this purpose, it is possible to detach the transparent lens from the housing of the signal lamp and to remove the optical fiber module from the housing and replace it with a new, undamaged optical fiber module. After attaching the dissolved or a new lens, the signal light can be used immediately without having to be completely replaced.

The light guide module, for example, perform the light function of the tail light of the vehicle, which in addition to the fact that the tail light function of the signal light according to the invention by the simple replacement of the light guide module in case of damage to the signal light can be restored immediately, also has the advantage that in the case of Damage only the lens and not the fiber optic module, the tail light function is maintained unchanged. If, in fact, the lens is damaged, moisture and / or dirt penetrates the interior of the indicator light through the damaged area of the lens.

In the known signal light, this leads to the fact that the light source in the form of a light bulb, which performs the tail light function, is damaged or dirty and thus the tail light function is no longer guaranteed. On the other hand penetrates moisture and / or dirt in the interior of the signal lamp according to the invention and is deposited on the at least one light guide, so the integration of the circuit board in the terminal housing causes the light emitting diode neither moisture nor dirt comes into contact and thus the light output is further ensured by the light emitting diode, since the electronics for controlling the LEDs is protected. The light propagates in the signal lamp according to the invention over the light guide over substantially the entire width of the signal light out, so that even if individual areas of the light guide are covered with dirt, the tail light function is still met, as opposed to the direction of travel of the light guide the light emitted by the vehicle is still visible along partial regions of the light guide and thus the tail light function is indeed impaired, but still to a large extent is present and thus the vehicle is still recognizable from behind as a vehicle.

It is provided according to a development of the invention that at least a portion of the terminal housing is integrally formed with the light guide. The light guide can therefore be made together with the terminal housing or a portion of the terminal housing, for example, from a transparent plastic material in a single shaping step, so that the light input surface of the optical fiber from outside the terminal housing or the portion of the terminal housing against the ingress of moisture and dirt is protected when the terminal housing is closed. The terminal housing therefore forms together with the one or more light guides and the printed circuit board arranged in the interchangeable light conductor module, which can be used by simply opening the housing of the signal light in the signal light and then immediately after the closure of the lens is used again without being completely replaced to have, as is the case with known signal lights, which are not modular.

It is provided for this purpose according to a development of the invention that the light guide together with the terminal housing in Housing the signal light is releasably fixed and the terminal housing first electrical connection elements are provided which can be coupled with provided in the housing second electrical connection elements for producing an electrically conductive connection. If the optical fiber module, as described above, inserted into the housing of the signal light, so only the provided in the housing second electrical connection elements must be connected to the connection housing of the optical fiber module provided first electrical connection elements and the signal light is ready for use again. It is possible to provide the second electrical connection elements such that an electrical contact with the first electrical connection elements automatically takes place when the light conductor module is inserted into the housing of the signal light, for which purpose the second electrical connection elements can be arranged in the form of sockets, in which the connector designed as the first connecting elements of the terminal housing are used automatically and correct polarity, so that a malfunction is excluded even by untrained users. According to an alternative to this, the second electrical connection elements may be in the form of simple and inexpensive cable shoes which are unambiguously marked with regard to the polarity and which can be connected to the connectors of the light conductor module.

In both cases, it is ensured by the modular design of the fiber optic module with terminal housing, circuit board, fasteners and optical fibers or optical fibers that a complete and functional unit to form the example to be called taillight function can be integrated into the signal light. Even with a partial damage of the light guide module in the region of the light guide maintaining the tail light function can be achieved that instead of only one light guide two light guides are used, since the risk of simultaneous damage of two light guides, which leads to a total failure of the light guide is less as the risk of damage to only a single light guide. If one of the two light guides is damaged, the tail light function is retained. If both light guides are partly damaged, the light area of the signal light with two light guides is larger than that of only one light guide so that the vehicle can still be recognized by the tail light function ,

It is provided according to a development of the invention that the terminal housing is formed transparent at least in the region of a surface connecting the light guide to the terminal housing and the Lichteinkoppelbereich of the light guide is provided with a Lichtabstrahlcharakteristik the light emitting diode adapted coupling surface. Thus, the light at the coupling surface of the light emitting diode in the light guide can be efficiently coupled according to the emission characteristics of the light emitting diode and for this purpose, the coupling surface may be formed, for example lenticular, so that a bundling of the light emitted by the light emitting diode in the Lichteinkoppelbereich of the light guide is possible ,

It is also provided according to a development of the invention that the terminal housing is transparent in a region which is arranged opposite a surface connecting the light guide with the connection housing surface. In other words, this means that the connection housing in the region of the rear side of the printed circuit board, wherein the light-emitting diode or the light-emitting diodes for coupling light into the optical waveguide or the light guide is provided on the front side of the printed circuit board, is transparent and formed at an area which is opposite to a disposition area of a light emitting diode on the back surface of the printed circuit board. In this way, light can be emitted from the arranged on the back of the printed circuit board light emitting diode and out of the terminal housing on the transparent surface of the terminal housing. The light emitted by the LED arranged on the rear side of the printed circuit board thus exits from the terminal housing and can be used, for example, to form a side-limiting light function. In this way, a further functional integration is achieved in the signal light according to the invention, so that a correspondingly designed light guide module also provides the functionality of providing a side limiting light function. In this connection, it is also possible that the transparent surface is formed with an optical element for scattering light, so that the side boundary light does not appear as a light spot but as a scattered light beam.

It is provided according to a development of the invention that the terminal housing has an integrally formed with the light guide housing half and forms together with a second housing half an interior space for receiving the printed circuit board. In this case, the terminal housing may have a recess formed for receiving itself from the terminal housing extending electrical connection elements and be formed against the ingress of moisture, in particular be welded.

In the interior formed by the two housing halves, the circuit board can be used, either on the one or the optical fibers facing the front with one or a plurality of light-emitting diodes is provided or is also provided on the back with one or more light-emitting diodes, which are required to provide a Seitenbegrenzungslichtfunktion. After inserting the circuit board, the two housing halves are welded together and provided on the circuit board first terminal elements are located in the recess of the terminal housing and are sealed when welding the two housing halves in the welded joint. The connection elements can then be introduced in the arrangement of the light guide module in the interior of the housing of the signal light in a provided for example in the housing, designed with electrically conductive connecting elements socket, so that the connection elements contact each other.

For this purpose, according to a development of the invention, the terminal housing with the printed circuit board in the interior defining and the first connection elements in the region of the recess of the terminal housing defining dowels be provided. The printed circuit board has corresponding bores which ensure that the connecting elements come to lie in the region of the recess and the light-emitting diode or light emitting diodes on the coupling surface to the one or more optical fibers and the optionally provided on the back of the printed circuit board light emitting diode to the transparent surface be arranged in the correct position.

According to a further development, the invention also provides that the light guide or the light guides extend substantially along the entire width of the signal light in the height direction of the signal light in the region of the center of the height and with a from the region of the middle of the height in the downward direction directed curved extending portion are provided. In this way it is achieved that the one or more light guides substantially completely through the interior of the housing in the width direction, but not along the peripheral edge of the housing, since this is the most at risk of damage and by the extension of the light guide with the curved portion a correspondingly large radiating surface is available for the formation of the taillight function to be named, for example.

In order to improve the light-emitting effect of the optical waveguides, it is provided that the optical waveguide or lines in the region of the light outcoupling surface are substantially semicircular in cross-section and provided with light-deflecting means, in particular prisms, on a surface opposite the light-outcoupling surface. Depending on the desired light scattering and the light distribution to be generated, the angle of the scattering of the emitted light can be changed by changing the prism angle and / or the prism pitch and / or the depth of the prisms.

It is also provided according to a development of the invention that the light guide or the light guide are releasably secured to a holding means provided with locking means, which is formed following the light guide or in the extension course and on an active surface, which provided with a light-deflecting means surface of the Optical fiber in the mounted state is opposite, is provided with transversely to the longitudinal extent of the holding device arranged rod-shaped elements and between the active surface and the surface, an air gap is formed.

About the locking means, the optical fibers can be releasably secured to the holding device, for example, be clipped. The holding device may be provided with Schraubbohrungen, by means of which the holding device can be defined together with the light guides and the terminal housing in the interior of the housing of the signal light. The effective area provided with rod-shaped elements ensures that the optical impression of a constant width of the light guides along their entire longitudinal extent also arises in the non-illuminated state of the light guide. The air gap formed between the optical waveguides and the active surfaces of the individual arms of the holding device ensures adequate thermal insulation of the optical waveguide made of a transparent plastic material with respect to the heat emitted by the bulbs formed, for example, by incandescent lamps. The holding device therefore serves the releasable fixing of the light guide module in the housing of the signal light and at the same time the protection of the light guide relative to the heat emitted by the other bulbs.

According to a further development of the invention, it is also provided that the signal light has a covering device which overlaps the light guide along a partial region of its longitudinal extension and at least one upper side of the connection housing. This ensures that in a transparently designed terminal housing light from the terminal housing does not escape into the region of the emission surface of the lens and the light emitted by the optical fibers in the direction of the lens does not merge seamlessly in the range of the Seitenbegrenzungslichts, but a defined optical separation between the Both light functions is created and thus a clear separation of functions is achieved in a truly one-piece module executed.

Finally, according to the invention, a light guide module is provided which at least one light guide and a printed circuit board and a Circuit board receiving terminal housing having connecting elements and at least one light emitting diode is provided on the circuit board and the optical fiber is formed integrally with at least a portion of the terminal housing. The light guide module can be provided as a ready-to-connect module, which only needs to be supplied with electrical voltage and, for example, for the formation of a signal light, as described above, are used. In addition, it is also for use at another lighting device providable, which can fulfill a lighting function with the Lichtleitmodul.

The invention is explained in more detail below with reference to the drawing, which shows in:

1 a top view of an embodiment of the signal light according to the invention with a modular light guide;

2 a perspective view of the light-guiding element in an exploded view;

3 a perspective view similar to that after 2 showing the light guide together with a cover in the ready-to-install state;

4 an enlarged view of the arrangement of the light guides in the holding device in section;

5 an enlarged view of the region of the light coupling in a light guide; and

6 a plan view into the interior of the terminal housing with disposed therein printed circuit board, without the second housing half.

1 The drawing shows a plan view of an embodiment of a signal light 1 according to the present invention. The illustrated signal light 1 is intended to be mounted on a towed vehicle such as a semi-trailer of a truck. The signal light 1 but can also be attached to other vehicles or motor vehicles.

The signal light 1 has an elongated in the width direction B housing 2 , which on its upper side, ie in the main direction of the light emission with a detachable transparent lens 3 is provided. To release the lens 3 only need four screw connections 4 be solved so the interior 5 of the housing 2 is accessible. In the interior 5 are several bulbs 6 . 7 and 8th arranged in appropriate receptacles. The illustrated bulbs are incandescent, but it is readily apparent to one skilled in the art that these bulbs can also be replaced by bulbs based on light emitting diodes or other bulbs.

In the illustrated embodiment, the bulbs are used 6 as reversing lights, the bulbs 7 serves as a flashing light and the bulb 8th serves as a fog tail light. Another light source 9 in the form of a soffit serves as lighting for a license plate, not shown in detail.

As it is readily apparent, is located in the interior 5 the signal light 1 a fiber optic module 10 arranged, which in the illustrated embodiment, two light guides 11 . 12 which extends largely over the entire width extension B of the signal light 1 extend. At the front end 13 the light guide 11 . 12 is about closer to 6 the drawing apparent, there schematically illustrated light-emitting diodes 14 Light in the light guides 11 . 12 coupled.

In the area of the front end 13 there is a connection housing 15 arranged, which is closer to 2 and 3 the drawing is visible.

2 The drawing shows a perspective view of the light-guiding element or light guide module 10 in an exploded view.

The fiber optic module 10 indicates the already mentioned two light guides 11 . 12 on, which are made of a transparent plastic material, and in one piece with a first housing half 16 , The housing half 16 has a rectangular shape and has on its underside a recess 17 , the closer still by means of 6 the drawing is visible.

Because the case half 16 together with the two light guides 11 . 12 is made, it also has a transparent plastic material as a material, this also applies to the in 2 the drawing illustrated second housing half 18 so that the connection box 15 overall is also transparent.

In the 6 shown schematically and on a front side of the circuit board 28 arranged two LEDs 14 couple light into the two light guides 11 . 12 a, being used for this purpose, as stated by 5 the drawing is shown, light coupling surfaces 19 are provided in the form of lenses, which are for a bundling of the light of the light-emitting diodes in the light guide 11 . 12 to care. The light guides 11 . 12 are at their, the radiating surface 21 opposite side 20 provided with light deflecting means in the form of prisms. These prisms make sure that of the light emitting diodes 14 coupled light respectively closer in the direction of 4 the drawing apparent radiating surface or Lichtauskoppelfläche 21 is deflected so that the light guides 11 . 12 along their entire longitudinal extent appear largely brightly lit.

Because of the light-emitting diodes 14 Light emitted also the transparent terminal housing 15 Enlightened, is a non-transparent cover 22 provided that a top 23 of the connection housing 15 and a subarea 24 the two light guides 11 . 12 to maintain a predetermined distance to a side-limiting light function different from that in 6 the drawing apparent light emitting diode 25 is provided. The at the back of the circuit board 28 arranged light emitting diode 25 emits light through an in 2 and 3 the drawing apparent surface 26 through, which in the embodiment of the terminal housing 15 is also made transparent from a transparent plastic material. In the area of the area 26 is located on the basis of 5 the drawing apparent optical element 27 arranged in the shape of a plano-convex lens.

The light-emitting diodes 14 . 25 are located as surface mounted components on a circuit board 28 arranged, which in the interior 29 of the connection housing 15 can be arranged. For this purpose are on the first half of the housing 16 dowels 30 provided in common with the first half of the housing 16 be trained and in drilling 31 the circuit board 28 intervene and in this way the circuit board 28 in the interior 29 Align in the correct position, so that the light-emitting diodes 14 . 25 their respective Lichtabstrahlcharakteristik are placed correctly.

After the circuit board 28 in the interior 29 has been arranged, the second housing half 18 on the first half of the housing 16 put on and then the two housing halves are welded together fluid-tight, so that the ingress of moisture into the interior 29 of the connection housing 15 is safely avoided.

The closer to 6 the drawing apparent recess 17 is then potted with potting material, so that along the first electrical connection elements 32 in the form of plugs no moisture in the interior 29 can penetrate. The electrical connection elements 32 provide with not shown second electrical connection elements, located in the housing 2 are arranged, an electrical connection to the circuit board 28 from the on-board electrical system of the vehicle, not shown forth.

Before the fiber optic module 10 in the interior 5 of the housing 2 is used, it is at an in 2 the drawing apparent holding device 33 arranged, which is made of a temperature-stable plastic material and along its longitudinal direction with locking lugs 34 is formed, the releasable fixing of the two light guides 11 . 12 on the holding device 33 serve.

The holding device 33 has at its top or effective area 35 transverse to the longitudinal direction of the two support rods 36 extending rod-shaped elements 37 for one along the entire longitudinal extent of the light guide 11 . 12 ensure a consistent visual impression of the light guide. As it is closer to 4 the drawing is apparent, is between the two light guides 11 . 12 and the effective area 35 an air gap 38 provided, which of the thermal separation of the optical fibers 11 . 12 from the effective area 35 serves. In addition, the air gap ensures 38 for that of the bulbs 6 . 7 . 8th . 9 heat dissipated by heat conduction to the light guides 11 . 12 passes and thus the optical fibers are thermally less stressed. The holding device 33 covers the light guides 11 . 12 From the bottom largely completely off and protects the light guide as well as against the radiation acting on the light guide heat.

The completely pre-assembled fiber optic module 10 can in the interior 5 of the housing 2 be used and ensures a largely uniform distribution of light in the direction of the lens 3 out. Suffers the signal light 1 Damage to the shape, such as the lens 3 gets a jump or breaks out at a sub-area, so inevitably penetrates through this damage site moisture and / or dirt in the interior 5 the signal light 1 one. This dirt also accumulates on the part of the light guide adjacent to the damaged area 11 . 12 and at this point locally reduces the luminosity of the light guide. But since the light guides 11 . 12 largely along the entire width direction of the signal light 1 extend, thereby the luminous intensity of the light guide is not affected in the areas spaced from the point of damage and the light function provided by the light guide, such as the function of a tail light, is not affected, the vehicle is still recognizable from behind as such. That by the surface 26 emitted light of the LED 25 provides the light function of a side marker without the need for a separate light guide module 10 Present bulbs would be necessary. The fiber optic module 10 can look for an alternative even without the Functionality of the side boundary lamp be formed, in such a case, the light emitting diode 25 to be eliminated.

The signal light 1 According to the invention ensures that the vehicle continues to be recognizable as a vehicle despite damage to the signal light for the other road users and even if damage to the signal light is so strong that the light guide module 10 itself is severely affected and needs to be replaced, it is only necessary, the screw 4 to solve the lens 3 remove the damaged fiber optic module 10 to remove and against a new fiber optic module 10 exchange. On the terminal housing provided dowel pins 39 ensure a correct positioning of the fiber optic module 10 in the case 2 and for a correct position positioning of the connecting elements 32 relative to the housing provided in the housing and not shown second electrical connecting elements, which may be sockets in which the connector designed as a first connecting element 32 be introduced.

After mounting a possibly also renewed lens 3 can the signal light 1 be used again as intended, without that it would have to be completely replaced, as is the case with known signal lights. Since such a complete replacement of the signal light is associated with high costs, is often waived in known signal lights on the replacement and thus waives the light function, which is provided by the signal light and the also damaged bulb. The signal lamp according to the invention makes it possible to maintain the overall light function of the signal light by the partial replacement of damaged components or quickly restore.

With regard to the features of the invention which are not explained in greater detail above, reference is expressly made to the claims and the drawings.
