Definitions

  • the invention relates to a luminaire with function monitoring for vehicles, in particular for rail vehicles.
  • Taillights is required for safe rail operation.
  • the regulations UIC 532 and UIC 534 and DIN 6163 which are relevant for international railway traffic, determine the arrangement of the tail lamps, the light color, the light exit angle and the required light intensity.
  • the function is checked either by means of a visual inspection by the railway personnel or by means of technical equipment.
  • a frequently used method determines the operating state of a light source (operation, short circuit, interruption) by measuring the lamp current (eg in DE 296 12 300).
  • DE 199 29 430 B4 a method is described which describes the function control of luminaires with LED light sources (light emitting diodes), by means of which an error signal is output as soon as a defined percentage of LEDs of a luminaire has failed.
  • LED light sources light emitting diodes
  • the invention is therefore based on the object of specifying a luminaire for rail vehicles with functional monitoring, which continuously measures the light intensity emitted by it and emits an error signal when it drops below a predefinable minimum luminous intensity.
  • a luminaire is equipped with at least one light sensor, which continuously determines the luminous intensity of the luminaire and triggers an alarm signal when the luminous intensity falls below a predetermined level.
  • the advantage can be achieved to be able to use the effective light intensity of a lamp as a measure of the functionality of this lamp.
  • the determination of the functionality by means of indirect measured variables eg current levels of the lamps
  • This is particularly disadvantageous, since by means of these indirect measured variables no statements about the effective light intensity of a lamp can be taken.
  • the aging of bulbs can not be detected by the methods according to the prior art.
  • the present invention offers the particular advantage that the effective light intensity of a lamp is used as a criterion for assessing the functionality. As a result, a much safer assessment of the functionality is given as in the method according to the prior art.
  • At least one light sensor for example a solar cell or a photosensitive resistor or otherwise any optoelectronic component
  • at least one light sensor for example a solar cell or a photosensitive resistor or otherwise any optoelectronic component
  • a particular embodiment of the invention provides to arrange the light sensor within a reflector housing.
  • a further preferred embodiment provides for the arrangement of the light sensor outside the reflector housing, with the advantage that it is also possible to take into account a (aging-related) haze of a lens covering the reflector housing when measuring the light intensity.
  • a diagnostic device receives the output from the light sensor, the light intensity of the lamp proportional electrical signal and compares this light intensity with a predetermined minimum light intensity and outputs an error signal when the measured light intensity is less than the minimum light intensity.
  • the design of the diagnostic device is to be based on the respective purpose and the respective vehicle.
  • a digital transmission of information from the diagnostic device to the vehicle electronics is possible, wherein either the digitally coded value of the measured light intensity or (simplified) a good / bad signal is transmitted.
  • analogue information transmission by means of an analog signal is also possible, whereby a voltage or current signal proportional to the value of the measured light intensity (for example a 4 to 20 mA current loop) is transmitted to the vehicle electronics.
  • a preferred embodiment of the invention relates to lights with LED bulbs. Such lights are often constructed by means of an array and individual LEDs, which are soldered to a printed circuit. It is recommended to insert one or more light sensors into this array of LEDs and to solder these light sensors together with the LED in one work step. As a result, the advantage can be achieved to be able to produce a lamp with function monitoring very simple and inexpensive, since in this embodiment, the separate assembly and electrical contacting of the light sensors can be omitted. Depending on the required number of LEDs for the purpose of the type and number of light sensors is set.
  • the present invention is not limited to use in rail vehicles. This principle of a lamp with function monitoring is applicable for all (in particular safety-critical) lighting or display applications.
  • Another application of this invention may advantageously be for permanently mounted safety-criticalfacts lactates. Display applications occur, for example, in the monitoring of anti-collision lights on tall buildings.
  • Fig.l shows an example and schematically a lamp for rail vehicles with function monitoring.
  • a luminaire 100 comprises a reflector housing 200, a diffusing screen 400 and a luminous means 300.
  • the luminous means 300 may be embodied, for example, in the form of an incandescent lamp or one or more light-emitting diodes. The operating principle of the luminous means 300 is irrelevant to the subject invention.
  • the luminaire 100 comprises a diagnostic device 500 and a light sensor 600 connected to it.
  • the light sensor 600 is arranged within the reflector housing 200 in this exemplary embodiment.
  • the arrangement of the light sensor 600 is irrelevant to the subject invention, it is for example possible to arrange the light sensor outside the reflector housing 200.
  • required for the operation of the lamp 100 components in particular a power supply are not shown in Fig.l for simplicity.
  • the light sensor 600 determines the light intensity emitted by the illuminant 300 and transmits it to the diagnostic device 500. If the light intensity determined by the light sensor 600 falls below a predeterminable minimum value, then the diagnostic device 500 emits an error signal 700 to the interface of the rail vehicle (not shown).
