Definitions

  • the invention relates to a traffic signal generator referred to in the preamble of claim 1 Art.
  • Traffic signal transmitters are known in which individual light signal transmitters with their own inner housing and an outer pane have been installed in a common outer housing. This embodiment requires a relatively large space requirement of a plurality of individual light signal transmitter containing traffic signal generator and requires a relatively high installation and maintenance costs.
  • the invention has for its object to provide a traffic signal transmitter of the type mentioned, which results in a simplified compact design with reduced installation and maintenance.
  • the inventive design of the traffic signal generator results in an outer housing with low space requirement, in which the at least one signal light source is directly attached, wherein the outer discs or outer lenses are also mounted directly in a front surface of the outer housing.
  • the traffic signal transmitter according to the invention preferably has an optical system with high efficiency. This is achieved by a central LED light source, the laterally emitted light (in the angular range between about 45 ° and 90 °) is deflected either by means of a reflector or by means of an annular lens in the usable angle range between 0 ° and about 45 ° ,
  • the light is parallelized by a collimator lens (Fresnel lens) and finally deflected by an optimized structure of the outer lens in the specified by the standard angle range without unnecessary lateral stray light.
  • a collimator lens Resnel lens
  • the outer disks or outer lenses have a substantially planar shape, resulting in a reduction of the lateral radiation angle. Furthermore, as a result, the phantom light caused by solar radiation is substantially reduced, so that in many cases the commonly used barges for shielding extraneous light can be dispensed with.
  • each individual signal light source is assigned separate driver circuits arranged spatially close to the light source.
  • the drive circuits for a plurality of signal light transmitters are combined to form a common unit which is mounted in the outer housing at a location accessible from the outside by a maintenance flap, so that maintenance and, if necessary, replacement of the driver circuit without extensive opening of the Outer housing is possible.
  • Advantages of a driver circuit are simplified installation, possible component savings (thus reducing costs) and a common interface for the external connection.
  • FIG. 2 is a partially sectioned side view of a first embodiment of the outer housing 100 of the traffic signal emitter 100.
  • This outer housing 100 has a bottom surface 101 and a front surface 102, wherein in the outer housing 100, three light-emitting switches, schematically designated 2, are arranged, each comprising a signal light source 3 and a lens assembly generally designated 200.
  • the lens assemblies 200 are either mounted on or recessed into the front surface 102 as shown in FIGS Figures 3 and 4a, 4b shown ..
  • FIG. 1 are the individual light signal generator 3 supplied by respective driver circuits (4) with energy, while in the embodiment according to FIG. 2 a common driver circuit for the light signal generator 3 is provided, which preferably according to FIG. 6a may be mounted on a service door 104 in one of the side surfaces 103 or the bottom surface 101, so that a maintenance and optionally an exchange of the driver circuit 4 without comprehensive opening of the outer housing 100 is possible.
  • the entire outer housing 100 is pivotably arranged relative to an outer shell 103a, wherein the outer housing with the bottom wall 101 and the side walls 103 can only have the form of an open frame structure, so that all components arranged in the outer housing are freely accessible after the outer shell has been pivoted for maintenance purposes are.
  • the attachment of the entire signal transmitter can take place here either via the outer shell 103a or via the outer housing 100.
  • FIGS. 5a to 5d These are, without limitation, merely some of the conceivable embodiments of cross sections of the outer housing of the traffic signal transmitter 100 shown, which are made possible by the inventive design of the traffic signal generator.
  • the one-piece outer housing 100 after the FIGS. 1 to 3 be replaced by a number of modular outer housings 110, which can be combined by suitable only schematically indicated locking connections without tools in a variety of ways to a traffic signal generator.
  • the traffic signal transmitter according to the invention preferably has an optical system with high efficiency. This is achieved by a central LED signal light source 3, which is either in accordance with FIG. 8 Light emits only in a limited angular range or their laterally emitted light (in the angular range between about 45 ° and 90 °) either by means of a reflector 7 according to FIG. 9 or by means of a ring-shaped lens 7b according to ' FIG. 10 is deflected into the usable angle range between 0 ° and about 45 °.
  • the light is collimated by a collimator optics, preferably a Fresnel lens 8, and finally deflected by an optimized structure of the outer lens 9 in the angle range specified by the standard without unnecessary lateral scattered light.
  • a collimator optics preferably a Fresnel lens 8
  • an optimized structure of the outer lens 9 in the angle range specified by the standard without unnecessary lateral scattered light. Details of the outer lens 9 will be described by way of example in the embodiments of FIGS Figures 11 and 12 explained in more detail.
  • the outer lens 9 may preferably be connected to the Fresnel lens 8 and inserted into an opening of the front surface 102, as shown in FIG FIG. 11 is shown, or the lens assembly of the outer lens 9 and the Fresnellins 8 may be mounted on this front surface 102 from the outside.
  • the outer disks or outer lenses 9 on its outer side a substantially planar shape, as shown in the FIGS. 8 and 11 is shown, resulting in a reduction of the lateral radiation angle. Furthermore, as a result, the phantom light caused by solar radiation is substantially reduced, so that in many cases the commonly used barges for shielding extraneous light can be dispensed with.
  • the outer lens 9 may also have the conventional curved outer surface, as in FIG. 12 is shown.
  • a further control of the light emission in the desired manner can be achieved such that the parallel output light radiation of the Fresnel lens is spread by the outer lens.
  • the integrated traffic signal transmitter on the flat front surface 102 may have different displays.
  • FIG. 13a shows only schematically the arrangement of an information field 300 via the horizontally juxtaposed light signal generators 2, while FIG. 13b additionally shows a light bar 301 for the remaining remaining signal time of a particular signal generator.
  • a light indicator for the remaining residual signal time of a particular signal generator can also be arranged in a circle around the actual signal generator around, as this in FIG. 13d is shown.
  • additional (traffic) information can be displayed on one or more illuminated areas.
  • the traffic light function may be completely absent, as in FIG. 13c is shown so that the traffic signal transmitter contains only one or more luminous surfaces 304, which (traffic) information such.
  • FIG. 14 shows the use of a single, centrally placed LED light source 401, whose permanently switched on light after possible parallelization by means of a collimator lens (Fresnel lens) 402 passes directly behind the lens 404 LCD layer 403, whereby the texts or symbols generated in the illuminated areas 405 become.
  • the individual luminous surfaces 405 can be illuminated by separately controllable light-emitting diodes 410, as shown in FIG FIG. 15 shown ..
  • an integrated traffic signal generator which combines in an outer housing several functions that previously either did not exist or were previously available only as separate parts.
  • the traffic signal generator according to the invention may include light signal transmitters whose lens termination surface is (approximately) flat, that is similar to a monitor.
  • the light efficiency is slightly improved and the phantom light is slightly reduced compared to the conventionally used convex lens termination surfaces.
  • due to optimized lens structures for light distribution significantly less lateral scattered light is produced.
  • the described traffic signal transmitter has only one (outer) housing in which all components are mounted.
  • the previously commonly used signal generator had over own (inner) housing, which are no longer needed in the traffic signal generator according to the invention.
  • the omission of the additional inner housing has a positive influence on the thermal behavior, on assembly and material costs, as well as on the depth of the overall system. A flatter and slimmer case appears more aesthetic and elegant, which fits better into the modern cityscape.
  • Various variants of a modern housing form can now be implemented.
  • a flat front surface offers advantages in terms of standardization and construction, as well as aesthetics and elegance. This is implemented, for example, as a variant with (partly) transparent cover plate as front surface 102 or as a variant with flat / flush-mounted components in the front surface.
  • An integrated traffic signal transmitter may include traffic light signalers, which are supplemented by a "countdown" indicator. It is a luminous bar composed of individual bars according to FIG. 13 which shortens or lengthens its length depending on the mode of operation to indicate the remaining time remaining in the current traffic light phase (red or green).
  • the "countdown" display can be performed, for example, circular around a signal generator, vertically or horizontally as a straight line. In the case of a single vertically or horizontally arranged bar this can be switched between red and green lights.
  • the luminous lines can be realized differently. Conceivable, for example, the implementation by means of one or even more LEDs per line whose on / off displays the time course, or use of individual centrally placed LEDs whose permanently switched on light - after any parallelization by means of a collimator lens (Fresnel lens) - one directly behind the Through the lens located LCD layer passes, whereby the display of the time course is generated.
  • a collimator lens Resnel lens
  • An integrated traffic signal transmitter can be constructed either as a one-piece complete housing (reduced production and assembly costs) or modularly from individual housings.
  • the assembly of individual housings allows more flexibility and thus customer-oriented variants (one to four-signal housing). So that production and assembly costs do not get out of hand in this case, the modular individual housing components can be simply and quickly put together by means of "click" connections.
  • an integrated traffic signal transmitter may include electronic add-on modules that enable visual or non-visual communication with "smart" cars.
  • a visual information transmission is called the - not visible to humans rapid modulation of the radiated signal light, which can be received by cameras equipped with cameras.
  • Non-visual information transmission may be via radio or modulated infrared radiation.
  • the transmission of information takes place in one direction (from the integrated traffic signal generator to the car), but bidirectional communication is not technically excluded.
