  • the solar cell is arranged together with the control unit on a printed circuit board.

  • the temperature sensor can be integrated in the control unit, for example.
  • the temperature sensor may be a thermocouple or a temperature-dependent resistor.

  • Figure 2 is a schematic representation of the operating monitor in the first embodiment of the invention

  • the reflector lamp is, for example, an arc discharge lamp in which a lamp bulb 12, for example of quartz glass, is arranged within a reflector 11.
  • the light is generated in the lamp bulb 12, which preferably contains xenon or mercury vapor, by a gas discharge between an anode 13 and a cathode 14.
  • the lamp according to the invention is equipped with an operating monitor 10, which contains a printed circuit board 9, on which a plurality of electronic components of the operating monitor are arranged, and a current sensor 8.
  • the printed circuit board 9 with the electronic components is arranged, for example, laterally of the reflector 11 between the lamp cap 15 and the lamp head 16.

  • the operating monitor 10 is particularly suitable for detecting and storing the operating time and the number of operating cycles of the lamp.
  • the microprocessor 3 contains a program memory 7, for example a flash memory, a random access memory (RAM) 5, and a data memory 6, for example an EEPROM (electronically erasable programmable read only memory).
  • the microprocessor 3 is preferably connectable via an interface 17 to a computer 18. In this case, the microprocessor 3 can be controlled by the computer 18.

  • the operation monitor 10 includes a current sensor 8.
  • the current sensor 8 is a Hall effect sensor, by which the current with which the lamp is operated by measuring the magnetic field in the vicinity of a current leading conductor of the lamp is measured.
  • the evaluation of the signal of the current sensor 8 by the microprocessor 3 thus provides not only data on the operating time and the number of operating cycles, but also information about the current at which the lamp was operated during the operating period.

  • the power supply of the operating monitor is advantageously carried out by a solar cell 1.
  • the solar cell 1 is arranged, for example, on or on the printed circuit board 9. Characterized in that the power supply of the operating monitor 10 is performed by the solar cell 1, the operation of the operating monitor 10 is independent of the power supply of the lamp and thus not bound to a control gear of the lamp.
  • the solar cell 1 is preferably arranged such that during operation of the lamp at least part of the emitted light impinges directly or as stray light on the solar cell 1.
  • the solar cell can be arranged in the case of a reflector lamp behind the reflector, since the residual light passing through the reflector usually already suffices for the operation of the solar cell.
  • the solar cell 1 preferably has an output power of 5 mW or more.
  • the solar cell 1 is connected to a capacitor 2, which is charged by the solar cell 1 and can deliver the energy stored in this way if necessary.
  • the use of the capacitor 2 as a buffer advantageously makes it possible to design the solar cell 1 comparatively small and space-saving.
  • a solar cell can be used whose edge lengths are 25 mm or less.
  • the solar cell 1 is one rectangular solar cell whose edge lengths are 13 mm and 23 mm.
  • the microprocessor 3 is programmed, for example, with a program stored in the program memory 7, that reads the measured values of the temperature sensor 4 and of the current sensor 8 at fixed time intervals, for example once per second, and recognizes from these values whether the lamp is switched on or off.
  • the time profile of the temperature and / or the time profile of the current intensity or mean values of these parameters are also stored in the data memory 6.
  • maximum values of the temperature measured by the temperature sensor 4 or of the current intensity measured by the Hall sensor 8 can also be stored in the data memory 6 in order to be able to determine the cause in the event of a defect of the lamp.
  • the components of the operating monitor 10 described above are preferably made of materials that are resistant at least up to a temperature of 85 0 C. In particular, no plastics are used which do not withstand the comparatively high temperatures on or in the lamp.
  • the operating monitor according to the invention is preferably used in high-quality lamps, in particular in high-power lamps for applications in projectors, in semiconductor technology or medical technology.
  • the embodiment shown in Figure 3 is a lamp according to the invention High-power arc discharge lamp, which is typically operated at a power of 1000 watts or more.
  • the light is generated by a gas discharge in a lamp envelope 12, which includes a cathode 14 and an anode 13.

  • the electronic components of the operating monitor 10 which are not shown in detail in FIG. 3, correspond to the components of the operating monitor shown in FIG.
  • the advantageous embodiments and advantages of the operating monitor 10 described in connection with FIG. 2 also apply to the second exemplary embodiment.
  • An alternative to a solar cell as an autonomous energy unit is a battery o.a. With AC lamps, energy can be inductively branched off from the supply.
  • the solar cell (1) should have an output power of at least 5 mW, in particular of at least 10 mW.
  • a practicable upper limit of the power is a value of 40 mW.
  • a practicable upper limit of the area of the solar modules is a value of 7 cm 2 .
  • the entire energy unit should be designed so that it can withstand temperatures of at least 85 0 C without damage. In particular, it should withstand at least 125 0 C.
  • the size of the complete component should be chosen so that it does not interfere with the application. This is accomplished either by the fact that in a small-Watt discharge lamp the operating monitor including the solar cell is positioned behind the reflector and the non-reflected light serves as a feed for the solar cell.
  • the monitor preferably hangs on the current-supplying strand, which is shown in FIG. This strand is located in the beam path. Since it bothers the application, it should be as thin as possible. However, a cable thickness of typically 7-10 mm is required at up to 220 A.
  • the monitor should preferably be miniaturized so that a value of 10 mm as the width of the monitor is not exceeded and thus no additional shading occurs. A typical size of such a monitor is 35x8x4 mm.
  • the solar cell is often placed on a circuit board and packaged in a housing.
