Definitions

  • the present invention relates to a light signal for traffic engineering.
  • Light signals are used very widely to control traffic flows. In road traffic, it is usually the three red, yellow, and green light points that regulate the traffic flows. In railway traffic, signal plates with a multitude of luminous dots in the colors RED, YELLOW / ORANGE and GREEN are generally used, whereby the individual driving terms, such as DRIVING, SLOW RIDE, STOP and the like, can be formed from a combination of luminous dots, which are often also are still designed differently from network operator to network operator in accordance with national regulations.
  • a light measurement consists of the light source itself, in this case a large number of LED elements forming the red dot, and a receiving element, usually a light-dependent resistor (LDR) , a photodiode or a phototransistor.
  • LDR light-dependent resistor
  • An effective way to remove extraneous light is to use an optical one Filters to reduce the bandwidth of the receivable light spectrum.
  • an optical one Filters to reduce the bandwidth of the receivable light spectrum.
  • photodiodes with an IR filter are available.
  • the long-wave portion of sunlight for example, will continue to be noticeable here as a disturbance variable.
  • the present invention is therefore based on the object of specifying a light signal in traffic engineering which has an extremely reliable feedback channel for the detection of the lighting of a red dot.
  • the protection of the light sensor by the envelope body acts, which does not allow light components with an angle of incidence that differs significantly from the direction of reflection to hit the light sensor directly, and on the other hand, the light-absorbing coating or structure of the inner surface contributes to the fact that stray light components within the envelope body are effectively absorbed and therefore cannot reach the light sensor.
  • the enveloping body is essentially tubular.
  • the beam splitter can be configured to be essentially reflective for light that strikes the beam splitter essentially in the opposite direction to the radiation direction. In this way, such stray light components are reflected away from the light sensor.
  • the entire inner surface of the enveloping body is coated with a light-absorbing material or has a light-absorbing structure.
  • the inner surface of the enveloping body is at least partially lined with tubular structures aligned parallel to one another, the direction of propagation of which is essentially perpendicular to the direction of reflection.
  • the inner surface of the enveloping body can preferably be at least partially coated with Vantablack® or a comparable material.
  • the light sensor is designed with two channels and thus is redundant.
  • the invention is explained in more detail below with reference to the drawing, for example.
  • the figure shows a schematic representation of a light signal 2 with here only one light point 4.
  • a railroad signal can be constructed, for example, from a large number of such light points 4.
  • the signal system type L which partly defines the signal terms signaled in combination of several illuminated dots.
  • the glow of a green light signals a higher speed than, in comparison, the glow of a green and an orange light together.
  • the illuminated dot 4 is formed from a multiplicity of individual LED elements 6.
  • the lighting of the LED elements 6 generates a radiation cone 8, which is emitted in the desired color in the direction of an approaching rail vehicle via an optical element, such as a simple glass cover or a diffusing lens or the like.
  • a beam splitter 10 which is transparent to a portion 12 of the light emitted by the light spot 4 in a radiation direction 16 and which has a reflective effect for the other part 14 of the light emitted by the light spot 4.
  • the light signal 2 here comprises two light sensors 18a, 18b, which are arranged such that the part 14 of the light emitted by the light spot 4 reflected by the beam splitter in a reflection direction 20 is directed at the light sensors 18a, 18b.
  • the light sensors 18a, 18b are surrounded by a cylindrical envelope body 22 and are arranged in the bottom region of this envelope body 22.
  • the inner surface of the enveloping body 22 is made of a light-absorbing material 24 coated.
  • the enveloping body 22 has the function that, starting from the light sensors 18a, 18b, a good part of the distance from the light sensors 18a, 18b to the beam splitter 10 from the enveloping body 22 is protected against lateral light incidence on the light sensors 18a, 18b.
  • the signals from the light sensors 18a, 18b are evaluated in a control and evaluation unit 26. If the control and evaluation unit 26 now contains the instruction to let the illuminated point 4 light up from an interlocking (not shown here), the control and evaluation unit 26 controls the LED elements 26 accordingly and at the same time receives an actual one from the light sensors 18a, 18b Illumination of red dot 4 provides feedback on the desired illumination. External light 30, as indicated here for example by a sun symbol 28, is initially prevented from reaching the light sensors 18a, 18b directly by the cylindrical shape of the enveloping body 22. In the present embodiment, the inner surface is covered with a highly light-absorbing material, e.g. Vantablack® or comparable material, coated. In this way, even extraneous light that penetrates into the enveloping body 22 is absorbed on the inner walls of the enveloping body and therefore cannot be scattered onto the light sensors 18a, 18b as far as the bottom of the enveloping body 22.
  • a highly light-absorbing material e.g. Vanta
  • the red dot 4 Because of the two-channel design with the two light sensors 18a, 18b, it can be determined very reliably in this way when the red dot 4 is really emitting light and thus the intended signal term is also very definitely signaled as intended by the light signal 2. If the red dot 4 does not light up, although this has been reported accordingly by the signal box to the control and evaluation unit 26, a corresponding instruction for checking the light signal 2 is issued in the signal box by corresponding train employees and the light signal 2 itself is switched back to displaying a safe signal term , for example on the Signal term STOP, which is signaled by the lighting of one or two red illuminated dots.
  • a safe signal term for example on the Signal term STOP, which is signaled by the lighting of one or two red illuminated dots.
