Definitions

  • the invention relates to a method for operating high-pressure lamps without hot igniting. It also relates to a luminaire or a pair of luminaires with two Hochlichentla ⁇ tion lamps according to the preamble of claim 10.
  • High-pressure lamps are ignited with ignition voltages of 2 kV to 4 kV peak. If they are off in the hot state after a certain time period of its operation and will be turned on again, so we ⁇ a sentlich increased ignition voltage of 10 kV to 30 kV is neces- dig (hot re-ignition).

  • the high pressure discharge lamps should be as easy to build, without the problem of waiting from 2 to 15 min. for the time of recovery of the lamp to re-ignition with the usual ignition voltage.
  • the method according to the invention is thus a method for operating high-discharge lamps without hot ignition, in which two high-pressure discharge lamps are provided in one lamp.
  • the first lamp is switched off and the second lamp is put into a standby state for the period for the recovery of the first lamp, or remains in one in which it is not switched off.
  • the second lamp assumes the operating state without ignition. If it does not turn on the lamp again, the second lamp can also be switched off after the period of time for the recovery of the first lamp.
  • the invention makes use of the fact that the brightness of lamps is perceived logarithmically.
  • a single lamp is not perceived as half as bright compared to two lamps, but as almost as bright.
  • As half as bright, a single lamp is perceived only when it is 20 dB lower in the light output.
  • a single lamp is 3 dB lower than two lamps.
  • the invention makes use of this to provide a luminaire for illuminating a room, which has two high-pressure discharge lamps ⁇ .
  • the light When turned on, the light is then viewed, at least at a preliminary stage, when one of the lamps is lit.
  • When turned off, the light When turned off, the light is considered, if only one of the lamps is switched off and the second is in the standby state be ⁇ .
  • a recovery phase for the second lamp begins. If, during this recovery phase for the second lamp to a reclosing ⁇ turn of the lamp, so only the first lamp gezün ⁇ is det and switched on. Only after the expiration of the time ⁇ duration to recover the second lamp then the second lamp is ignited and turned on. Again, the light is then considered already turned on (temporarily), if only one of the two lamps of the light is actually turned on. The second lamp then follows.
  • Boosting means that the lamp is supplied with more power, so that in a high-pressure discharge lamp, the mercury typically present there more quickly enters the vapor phase, the plasma is hotter and the full brightness is reached earlier.
  • this diejeni ⁇ gen reclosing operations are counted, made after the expiry of the two phases of recovery, so that both lamps are powered up simultaneously. It is then boosted alternately the first and the second lamp, wherein ⁇ play at odd reclosing operations, the first lamp and at even reclosing operations, the second lamp.

  • the information line can be directly supplied with the supply voltage, so that logic one on the information line is defined in such a way that the voltage is present and logic zero is defined such that the voltage is not present.
  • this information line is an additional line, which bears the name Informationslei ⁇ tion because it serves only the transmission of information and not the transmission of the power.

This can determine whether this number is geradzah ⁇ lig or odd electronic ballast see, and depending on the first lamp or the second lamp can boosted ⁇ to, so turn on the light faster.

  • the invention be ⁇ rests on the experience that provides plenty of light from two lamps already sufficient to provide an on-state of the lamp is defined.
  • an operator only makes the off state so that the on state no longer lasts. So he usually wishes not the darkness, so that it does not hurt further, when in the temporary off state, the one of the two lamps (see lamp 12b in Figure 2) is still lit in the standby state.

Abstract

Des lampes à décharge haute pression ne peuvent être rallumées que par une tension d'allumage très élevée lorsqu'elles sont chaudes. L'invention vise à éviter l'allumage à chaud de lampes à décharge haute pression et concerne un procédé consistant à doter un luminaire de deux lampes à décharge haute pression (12a, 12b), lesquelles sont commandées de la manière suivante: lorsque le luminaire est mis hors circuit, la première lampe (12a) est mise hors circuit et la deuxième lampe (12b) est, pour la durée de régénération de la première lampe, mise en état de veille ou reste dans un état qui n'est pas hors circuit. Lorsque le luminaire est rallumé pendant cette durée de régénération, la deuxième lampe peut être immédiatement remise en fonctionnement, sans allumage. Si le luminaire n'est pas rallumé, la deuxième lampe (12b) est également mise hors circuit lorsque la durée de régénération est écoulée.
