Definitions

  • the present invention relates to a signal lamp according to the preamble of claim 1.
  • Signal lights are mainly used in traffic engineering. In many applications, a radiation characteristic is provided for the signal lights, which allows certain solid angles to be illuminated more than others. E.g. The signals of a signal lamp should be easily perceptible or readable along a path. However, road users on neighboring routes should not be disturbed by the signals given. For this purpose, signal optics are provided in known signal lights which direct the luminous flux emitted by a light bulb into the room in which reliable signal detection is to be ensured.
  • Such signal lights provided with light bulbs have various disadvantages.
  • the signal optics used contain e.g. one or two lens systems that reduce the luminous flux emitted by the light bulb due to the limited light transmission.
  • high quality lens systems are relatively expensive.
  • the light bulb provided in the signal light has a low efficiency and a short lifespan. The effort to operate and maintain the signal lights described is therefore great.
  • the light distribution can only be changed by exchanging the signal optics. The light distribution can therefore no longer be optimized after the signal light has been installed.
  • the present invention is therefore based on the object of providing a signal lamp which does not have these disadvantages.
  • the signal lamp according to the invention has a plurality of light sources which can optionally be aligned with the location of an observer.
  • the light sources can also be aligned in groups on different points.
  • an adjustment disk is used, through which the light sources are straight and / or e.g. are rotated concentrically and rotated in such a way that the desired light intensity distribution is achieved with the alignment of the light sources.
  • the ends of optical lines or light-emitting diodes are used as light sources. Red light-emitting diodes in particular have good efficiency.
  • FIG. 1 a shows a light-emitting diode LED which is held on the one hand by a base plate GP and an elastic layer ES and on the other hand by an adjusting disk VS and a front disk FS.
  • the light-emitting diode LED has a cylindrical body ZK and a connecting plate AP provided with connecting wires AD.
  • the wide radiators then illuminate the room; According to the invention, the wide-angle radiators are aimed at spatial points that require high luminosity.
  • a sliding layer GS is preferably provided between the adjusting disk VS and the front disk FS, which facilitates the mutual displacement of the adjusting disk VS and the front disk FS.
  • the light-emitting diode LED is held on the connection plate AP, the diameter of which is significantly larger than the diameter of the rest of the light-emitting diode body.
  • the elastic layer ES, the adjusting disk VS, the sliding layer GS and the front disk FS each have an opening suitable for receiving the light-emitting diode LED.
  • the opening GPO provided in the base plate GP serves to lead through the connecting wires AD.
  • the loosely held light-emitting diode LED can be tilted in the desired direction by displacing the adjusting disk VS relative to the front disk FS (see FIG. 1b). So that the desired tilt angle can be set precisely, the elastic layer ES presses the light-emitting diode LED upwards in such a way that the upper edge of the connection plate AP abuts the adjusting disk VS at one point. In FIG. 1b, the adjusting disk VS has been shifted to the right relative to the front disk FS in such a way that the light-emitting diode LED is tilted 5 ° to the left.
  • connection wires AD of the light-emitting diode LED are, for example, as shown in FIG. 2, connected to a fixed or flexible circuit board SP.
  • the switching plate SP, the base plate GP, the adjusting disk VS and the front disk FS are preferably connected to one another via screws SW1, SW2 and spacer elements DE1, DE2. It is particularly advantageous in the embodiment of FIG. 1 that almost the entire body ZK of the light-emitting diode LED is exposed and therefore emits light to the surroundings over the entire opening angle of the diode.
  • the light-emitting diode LED is movably mounted between the base plate GP and a holding plate HP on an elastic element EE.
  • the holding plate HP has an opening HPO for receiving the light-emitting diode LED, which has an enlarged diameter on the side facing the base plate GP has that is slightly larger than the diameter of the connection plate AP of the light-emitting diode LED.
  • the diameter of the opening HPO on the side facing away from the base plate GP is significantly smaller than the diameter of the connection plate AP.
  • the connection plate AP is therefore held in the opening HPO, but can be tilted sideways in any direction.
  • an elastic element EE could also be provided not only below, but also above the connection plate AP within the opening HPO.
  • the connecting wires AD of the light-emitting diode LED are connected to a circuit board SP, the distance from the base plate GP of which is determined by a first spacer element DE2 and which is fixed by a screw SW2 and a second threaded spacer element DE1 to the base plate GP and the holding plate HP connected is.
  • the connecting plate AP is pressed against the holding plate HP by the spacer element DE2.
  • the connection plate AP and the holding plate HP could also be connected directly to one another.
  • An adjusting disk VS and a front disk FS are also connected to the second spacer element DE1 by means of a second screw SW1.
  • the adjusting disk VS has a track VSB in which the screw SW1 is guided.
  • the light-emitting diode LED can therefore be inclined by the adjusting disk VS in any direction predetermined by the track VSB. It is advantageous in this embodiment of the signal light that the light-emitting diode LED is held and supported independently of the adjusting disk VS. This is particularly advantageous if several independent adjusting disks VS are used. Furthermore, this embodiment allows a simple assembly of the signal lamp, since the front screen FS and the adjusting disk VS can be mounted independently of the other elements with any adjustment mechanisms that may be present. It can be provided that the adjusting disk VS can be fixed relative to the front disk FS by the screw SW1 or more advantageously by the adjustment mechanisms described in more detail in FIG. 3. In the latter case, the adjusting disk VS is at most only guided by the screw SW1, but not held.
  • the adjusting disk VS is shifted to the left in such a way that the light-emitting diode LED is inclined to the left by 5 °.
  • the elastic element EE is slightly compressed on the left side and the elastic connecting wires AD have been slightly bent.
  • a spacer element DE12 is provided in the arrangement of FIG. 2b, which is passed through the web VSB with a reduced diameter. With the SW1 screw, only the front screen FS and the holding plate HP can be firmly connected to each other.
  • the adjusting disk VS is only carried by the shoulders of the spacer element DE12 and remains freely displaceable. The adjusting disk VS can therefore be moved by an adjusting device JV until one side of the web VSB abuts the spacer element DE12.
  • the adjusting disk VS could also be held laterally in guide rails.
  • 3 shows two mutually independent adjusting disks VS1, VS2, which are guided in guide rails SF1, ..., SF4 and can be optionally positioned by adjusting devices JV1, JV2 and JV3.
  • the light-emitting diodes LED in the first three quadrants of the signal light are set by the first adjusting disc VS1, which covers a circle segment of 270 °.
  • the remaining light emitting diodes LED which are shown with a slight hatching, are set by the second adjusting disk VS2.
  • the smaller diameter D1 is chosen in such a way that the light-emitting diodes to be set comprise LEDs and are deflected in the intended direction when the adjusting disk VS moves. If light-emitting diodes LED e.g. Should not be moved by the adjusting disk VS1, the openings have a larger diameter D2, which is dimensioned such that the relevant light-emitting diodes LED are not moved even with the maximum deflection of the adjusting disk VS1. For these light-emitting diodes LED, the second adjusting disk VS2 has openings which are provided with the smaller diameter D1. This principle can be used to determine which diodes can be adjusted by means of which adjusting disc VS1, ..., VSn.
  • the adjusting discs VS can consist entirely or only partially of translucent material.
  • the adjusting disks VS could also consist of a grid of rods or wires through which the corresponding light-emitting diodes LED are detected and moved. These measures prevent the adjusting disks VS1, ..., VSn from reflecting a larger part of the light emitted by the light-emitting diodes LED into the interior of the signal lamp.
  • FIG. 3a shows a sectional illustration of the guide rail SF2, which has two grooves in which the ends of the adjusting disks VS are guided.
  • the guide rails SF can be used in addition or as an alternative to the guide and / or support of the adjusting disk VS shown in FIG. 2b.
  • the adjusting devices JV1, JV2 and JV3 shown in FIG. 3 each consist of two angle pieces WS1, WS2, which are connected to one another by a screw JSW.
  • the elbows WS1, WS2 are rotatable e.g. connected to the bracket of the signal lamp or to the associated adjusting disc VS1, VS2.
  • the adjusting disk VS1 can therefore be displaced in any direction by the adjusting devices JV1, JV2. Limiting the deflection can e.g. through the SF guide rail or a VSB track.
  • adjustment devices can also be used, which enable the adjustment disks to be rotated selectively.
  • Adjustment disks of the same or different sizes can also be used, which are not arranged concentrically.
  • a smaller group of adjacent light-emitting diodes LED could be provided by a rotatable adjusting disk VS, for example, so as to be concentrically rotatable.
  • adjustable and non-adjustable light-emitting diodes LEDj or LEDf can be provided on a signal lamp, which are passed through openings GPO1, FSO1 or GPO2, FSO2 in the base plate GP and the front screen FS.
  • the adjustable light-emitting diodes LEDj can also be arranged individually or in groups, preferably in rotatable mountings, which can be adjusted by means of an adjusting disk.
  • the light-emitting diode LEDj is arranged in a tubular holder T, which has a base ST provided with connecting lines STC, a holding groove for the light-emitting diode LED and a by e.g.
  • the connecting wires AD of the light-emitting diode LEDf are in turn connected to the circuit board SP, which has an opening SPO for carrying out the holder T.
  • the connecting lines STC are led out from any suitable location of the holder T and connected to the circuit board SP.
  • the front window FS, the base plate GP and the switching plate SP are held together by means of a screw SW1, two preferably flexible spacer elements FDE1, FDE2 and a further threaded spacer element DE.
  • the adjusting disk VS which has an opening VSO for guiding the holder T, can also be fastened by means of a further screw SW2. By loosening the screw SW2, the adjusting disk VS, limited by the track VSB, can therefore be displaced such that the holder T can preferably be rotated through 360 °.
  • the holder T can be positioned particularly favorably if, instead of the rigid wing TF, elastic means connected to the holder T are provided, which are mechanically connected to at least the base plate GP or the windshield FS. If e.g. the wing TF shown in FIG. 4 would consist of an elastic material, the holder T could be tilted in any direction without loosening the fixed mechanical connection of the wing TF to the base plate GP and the front window FS.
  • elastic means e.g. Plastic rods, plastic rings or metal springs are used.
  • the wing TF shown in FIG. 4 could be mounted on spiral springs which rest on the base plate GP.
  • the ends of optical lines which may have attached lenses or other terminations, can be arranged individually or bundled in a suitable holder in such a way that the light emitted by them can be directed in the desired direction.
  • a suitable holder with optical lines fastened therein could be used according to the invention as shown in FIGS. 1-4.
  • the holders, terminations or housings for optical lines are very similar to those of the standard housings of the light-emitting diodes and, like these, normally have a lens.
  • bracket T the fasteners SW, DE and the adjustment devices JV can also be used in a modified form and can be adapted to the customary housing shapes and holders for the optical lines and light-emitting diodes.
  • a further influence on the radiation characteristic of the signal light can also be achieved by connecting optical elements such as lenses to the light-emitting diodes or fiber-optic lines.
  • optical elements such as lenses to the light-emitting diodes or fiber-optic lines.
  • this increases the manufacturing costs of the signal lamp.
  • a circuit board SP which is provided with electrical connections, is connected to a base plate GP which has openings GPO for the passage of the connecting wires AD of the light-emitting diodes LEDf1 and LEDf2.
  • Spacers DEa are provided between the plates SP and GP, are guided through the fastening screws SWa and are screwed to preferably further spacers DEb.
  • the spacer element DEb which is provided on the side of the base plate GP, preferably has a continuous thread, so that screws SWa, SWb can be screwed into the spacer elements DEb from both sides.
  • connection wires AD of the light-emitting diodes LEDf1, LEDf2 can therefore be easily passed through the openings GPO in the base plate GP and through contact openings in the circuit board SP until the connection plate AP of the diode body rests on the base plate GP.
  • the connecting wires AD are then soldered to the connections provided on the circuit board SP.
  • a front pane FS provided with openings FSO is connected to the base plate GP in such a way that the diode bodies ZK are guided into the openings FSO.
  • the connection plate AP of the diode body is thereby held between the base plate GP and the front window FS.
  • the height of the spacer element DEb which separates the base plate GP and the front pane FS, is chosen to be the same or a little larger than the height of the connection plate AP. This prevents an impermissibly high pressure being exerted on the connection plate AP.
  • the windscreen FS can then be e.g. assemble easily using the screws SWb, which are inserted into the spacer DEb.
  • the device shown in FIG. 5 therefore allows quick assembly and reliable fastening of the light-emitting diodes LEDf1,..., LEDfn, which in known solutions are only connected to the circuit board SP and held by the front pane FS.
