Definitions

the invention relates to a traffic signaling device for self-illuminating displays according to the Preamble of claim 1.
Incandescent or halogen lamps are used for traffic signaling devices with self-illuminating displays.
EP 0 467 034 there is, for example, a display device known for a variable message sign in which any advertisement, those from at least one non-changeable part of the ad and any display part that can be selected are shown.
the display part is by means of a processor-controlled matrix field display elements, each display element carried out by an illuminated optical fiber is.
the illuminated optical fibers are replaced by halogen lamps illuminated. This method is disadvantageous on the one hand the short lifespan of halogen lamps and on the other others their high energy consumption.
a signal lamp is known from EP 0 694 894, at least is partially provided with LEDs that inside the signal lamp from a first to at least a second Beam direction are tiltable and stored by adjusting discs can be positioned in groups.
the intended Holding device is, however, quite complicated and not suitable for easy assembly.
a preferred embodiment results from claim 3 by a toothing on the holding device, which also a particularly simple assembly of the holding device guaranteed.
a further improvement in the thermal conductivity of the holding device is achieved in that according to claim 4 the LED through a curable thermal paste in the Holding device is attached.
a particularly inexpensive embodiment results from a optical imaging device from a transparent Plastic such as polymethacrylate (PMMA, trade name Plexiglas) or polycarbonate (PC, trade name Makrolon) according to claim 6.
a transparent Plastic such as polymethacrylate (PMMA, trade name Plexiglas) or polycarbonate (PC, trade name Makrolon) according to claim 6.
the holding device and the Front panel are made of metallic materials.
FIG. 1 shows a section of a front panel 1 (for example made of aluminum) of a signaling device, for example a variable message sign or one Light signal system shown, through a hole 2 in the front panel 1, a light emitting diode 3 emits its light.
the LED 3 is in a tubular according to the invention Holding device 4 attached so that between the side walls of the light emitting diode 3 and the holding device 4 good heat dissipation contact is ensured.
the Holding device 4 can for example be made of a metallic Material or from a plastic with good thermal conductivity be made.
the LED 3 is there attached in the holding device 4 so that the Light emitting diode 3 emits light through a first opening (Light exit opening 5) of the holding device 4 through the Front panel 1 is emitted and the LED 3 through a second opening of the holding device 4 (Contact opening 6) is contacted.
the cathode connection 7 and the anode terminal 8 of the light emitting diode 3 are there connected to a control unit 11 via cable connections 10, which according to the ads to be displayed the LEDs 3 switches on and off.
the anode connection 8 and the cathode connection 7 are together with the cable connections 10 using a curable thermal paste 12 firmly connected, the thermal paste 12 is both a good Heat dissipation as well as a secure attachment of the LED 3 ensures in the holding device 4.
the holding device 4 In the direction the light exit opening 5, the holding device 4 is outside provided with a thread 13, which in a corresponding Thread in the hole 2 of the front panel 1 is inserted. This makes it particularly easy to assemble, if necessary again detachable connection between the front panel 1 and the Holding device 4 achieved.
an optical imaging device in the holding device 4 14 provided, with the help of the radiation characteristic adapts to the local conditions, so that the display is well recognized by all road users becomes.
the optical imaging device 14 is there made of glass or an inexpensive transparent plastic manufactured such as polymethacrylate (PMMA, trade name Plexiglas) or polycarbonate (PC, trade name Makrolon).
FIG. 8 is a conductive connection with the Holding device 4, which in this example made of metallic Material is made.
the Holding device 4 Through a conductive connection between the holding device 4 and the likewise a metallic material existing front panel 1 leaves a particularly simple contacting of the light emitting diode 3 by using a cable connection 15 to the front panel 1 is placed from the control unit 11. This allows the wiring effort reduce by a factor of two.
a connection (for example the ground connection) of all in the signaling device provided LEDs 3 is thus together via the front panel 1 and the holding device 4 connected to the control unit 11.
the holding device 4 has a toothing 9, which is a particularly simple assembly guaranteed with the front panel.
Figure 3 is shown schematically and simplified how a holding device 4 without an optical imaging device is arranged.
Figure 4 shows an embodiment in which instead of Light-emitting diode 3 is a light-emitting diode 16 on a semiconductor chip is arranged in a holding device 4.
a special one matched to the light emitting diode 16 on the semiconductor chip optical imaging device 17 is provided in the light exit opening 5 of the holding device 4 .
the contacting is carried out as in the previous embodiments via the cathode connection 7 and the anode connection 8 and cable connections 10 to the control unit 11. Also in this embodiment it is possible to make a connection through an electrical Contact via the holding device 4 to the front panel 1 to perform a reduced number of cable connections to achieve.
