Definitions

  • EP-0905 439 is a signal generator consisting of several light sources known by which, among other things, the avoidance of phantom light should be made possible.
  • This light signaling device also uses LED technology a rather complex optic consisting of a condenser disc specific condenser for each LED and a lens with a scattering optic which is composed of a large number of egg cells.
  • the weak point of this solution is likely in the rather modest luminosity of the There are LEDs, the structure of the large number of LEDs and the lamp optics costly.
  • EP-0649125 A1 also describes a device for preventing Phantom light known from two, with small, ball-shaped designed lenses fully occupied, which consists of each other with the plan back are attached so that a light shielding in the space Element, such as a perforated plate, fits.
  • This composite, only partially translucent plate is in the signal lamp between the light source and the Cover disc mounted.
  • This embodiment requires correspondingly stronger ones Light sources around the reduced light transmission of the shielding plate make up for it.
  • the invention has as its object a reflection protection for To create light signal systems to the above-mentioned disadvantages known Eliminate devices and clear detection of light signals without To allow delays.
  • the invention proposes the use of known ones Laminated glass or plastic panes in front of which one between the panes electrochromic unit contain through which the light transmission, possibly adjustable, can be changed, or the reflectance to regulate the Translucency can be changed.
  • Laminated glass or plastic panes in front of which one between the panes electrochromic unit contain through which the light transmission, possibly adjustable, can be changed, or the reflectance to regulate the Translucency can be changed.
  • these composite panes can either be flat panes the lamp optics or the sealing disc are placed inside or outside, they can form the shutter disk of the lamp or it as a flat disk can as a, provided with optically effective structuring the replace traditional locking disc.
  • the signal lamp or the light signaling system has one Light sensor which uses a control unit to control the voltage for the electrochromic unit controls so that the light transmittance, in relation to the Radiation intensity of the sun, is changed so that at high Sunshine reduces the light transmission of the pane as much as possible is.
  • the sensor may, e.g. by partial shading, so arranged that the position of the sun is also taken into account. It lends itself to the relative low voltage which is used for the electrochromic unit To purchase photocells.
  • the electrochromic disks are electrically controlled according to the invention so that the full when switching on the signal lamp Light transmission is given while the signal lamp is switched off Light transmission, according to the sun's rays, is reduced.
  • the invention does not rule out that the light transmission of the disc of the switched off Signal lamp is always completely reduced in daylight or that the Control of light transmission by a timer, possibly also combined with a light sensor.
  • the electrochromic unit of the composite panes also offers the possibility that not only the reflection mirror of the signal lamp but also the lamp optics, which is provided by structuring on the inner pane which completely eliminates the formation of phantom light.
  • the electrochromic unit in State of light transmission, especially towards the outside of the lamp, a light absorbing, e.g. matt, appearance and / or one absorbent paint, e.g. black, assumes.
  • Reflection protection results from the fact that the Light coloring (the corresponding color filter) of the signal lamp from the electrochromic Element is covered, which means that any reflections are caused by the smooth outer layer of the cover plate could not arise The phantom image in the corresponding signal color also results in this If it can be clearly recognized that the signal lamp is switched off.
  • FIG. 1 shows a traffic light in a schematic side view reflection protection according to the invention and schematically indicated Control unit for changing the light transmission of the cover plates of the individual signal lamps in relation to solar radiation.
  • FIG. 2 shows a functional diagram of the regulation of the light transmittance of the Disks of the individual signal lamps of a traffic light for the reflection protection according to the invention wherein the signal lamp R, with translucent cover, turned on and the signal lamps G and A are switched off and their cover plates are made opaque are.
  • FIG. 3 shows the schematic structure of a known electrochromic Unit as part of a reflection protection according to the invention can be used.
  • a traffic light in a conventional embodiment with housing 3 and stacked, colored signal lamps G, A, R which individually, by fixed flaps 3a protruding towards the front are partially shaded with a reflection protection according to the invention equipped.
  • the reflection protection exists from the respective cover disks provided with electrochromic element 4e 4g, 4a, 4r of the individual signal lamps G, A, R, from a light sensor 2 and out a control unit 1.
  • the electrochromic element which can be of various known types, is within the cover plate 4g, 4a, 4r of the individual signal lamps G, A, R, between an outer pane 4h and an inner pane 4i.
  • the inner surface of the inner pane 4i advantageously becomes a known optical one acting surface structuring which have a desired refraction of the The rays of light from the signal lamp also cause the light to be colored advantageously on the inner pane 4i.
  • the well-known electrochromic element 4e can be made in a known manner from several layers, or coatings, be constructed.
  • the transparent conductive coatings 4b are included electrical conductors 7r provide an adjustable electrical voltage through which the degree of reflection or the light transmission of the Compound disc 4g, 4a, 4r can be changed.
  • the control unit 1 with power connection la determines depending on the Power supply via the conductors 6g, 6a, 6r of the individual corresponding Light sources 5g, 5a, 5r of the signal lamps G, A, R and depending on the the, connected via conductor 2a, light sensor 2 detected light conditions Translucency of the respective cover glasses 4g, 4a, 4r. Is by the Light sensor 2 raised that the light conditions in the traffic light area to reflections and / or to form phantom light on the deactivated signal lamps could lead only to the corresponding cover glasses 4g, 4a the electrochromic element is electrically activated via the conductors 7g, 7a To reduce light transmission, or to cancel it completely.
  • this light beam L radiates directly, and reflects on the Reflection mirror 8, from the front through the cover plate 4r.
  • This Signal light L can be clearly recognized because the electrochromic element in the Cover plate 4r is not activated and is therefore transparent to the rays L.
  • electrochromic elements can of course also be used according to the invention Which are used by the action of an electrical voltage become transparent and are opaque without the influence of voltage.
  • the invention does not exclude that the disc used as reflection protection with electrochromic element of the traditional cover plate of the individual Signal lamps is upstream or downstream. Furthermore, it is not excluded that the Regulation of the light transmittance only by light sensors, only by a timer or by a combination of these.
