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 generation of the high ignition voltage has significant additional costs for the electronic ballast result.
- an increased transfer voltage by the electronic ballast must be provided with hot restrike, what if costs caused just ⁇ the electronic ballast.
- 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.
- a method according to claim 1 is provided. Further, a lamp according to the preamble of claim 10 is further developed by the characterizing features of claim 10 according to the invention.
- 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 ⁇ .
- the second lamp is preferred stand-by condition depending ⁇ but dimmed, so they fewer emits light, and thus are at, for example to 50% licht intricatesgedimmter lamp, the luminaire 75% less light in the excluded switching state from when the switched Status.
- the lamp can also be operated pulsed in the stand-by state, so that it emits flickering light. In this way, the operator is made clear that the lamp has tatsumble ⁇ Lich initiated the shutdown process.
- the second lamp is still turned on so far that they can resume the operating state without re-ignition at any time, or the first lamp has already recovered and can with ordinary ignition voltage of 2 kV to 4 kV peak to be detonated.
- the second lamp can be operated with increased power so that it emits more light, and that until the first lamp is ignited.
- the absence of a lamp in the on state can be compensated.
- 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 lamp according to the invention is a conventional Leuch ⁇ te with two high-pressure discharge lamps, as is known in the art, that a lamp with an e- lektronischen ballast, which may for example comprise a microprocessor, wherein the lamp is connected to a light switch, with the it is switched on and off.
- a lamp with an e- lektronischen ballast which may for example comprise a microprocessor, wherein the lamp is connected to a light switch, with the it is switched on and off.
- the supply voltage of the electronic ballast is provided directly via the light switch.
- an information tion line via which the electronic control gear (specifically the microprocessor) an infor mation ⁇ about the switching state of the light switch übermit ⁇ telt is.
- 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.
- the electronic ballast see designed (ie, for example, his microprocessor programmed to) to determine the number of switch-on of the lights after elapse of a predetermined minimum period of time to the previous switch-off. 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.
- FIG. 1 schematically shows the luminaire according to the invention in the switched-on state
- 2 shows schematically the luminaire according to the invention after switching off in stand-by mode
- FIG. 3 schematically shows the luminaire according to the invention in the switched-off state
- FIG. 4 schematically shows the luminaire according to the invention directly after switching on
- FIG. 5 shows schematically the inventive method in a schematic diagram ⁇ .
- the luminaire shown in FIGS. 1 to 4 consists of an electronic ballast 10, which may comprise a microprocessor (not shown) and two high-pressure discharge lamps 12a and 12b.
- the lamp according to the invention includes a light switch 14, which is shown in Figure 1 as turned on. In the on state, the electronic ballast 10 drives the two lamps 12a and 12b as indicated by the arrows, and these two lamps 12a and 12b are turned on and output light (shown schematically).
- the invention is also applicable to a pair of lights from geographically adjacent adjacent lights, each comprising one of the lamps 12a and 12b. However, the common ballast 10 and the one common light switch 14 are essential.
- the inventive method begins according to Figure 5 with the turning off the light switch. After the light switch is switched off, the off ⁇ takes place switch from the first lamp, here the lamp 12a and the further operating the second lamp in standby mode for a stand-by time period T.
- the electronic ballast 10 is still controls (indicated by the dashed arrow) the lamp 12b, which still emits light.
- FIG. 2 shows that the lamp 12b emits less light than in the switched-on state as in FIG. 1, ie it is dimmed in relation to this state.
- the standby mode does not necessarily have to be associated with dimming, the lamp 12b could also define its normal operating state as a standby mode.
- the lamp may also be pulsed by the electronic ballast and flicker.
- the situation of the lamps switched off is shown in FIG.
- the switch 14 is OFF, and the electronic ballast 10 is no ⁇ cal control pulses to the lamps 12a and 12b from which give corresponding to no light from ⁇ .
- the second time T is first awaited, previously dimmed lamp 12b that is also needs to recover to immediately zündfä to be ⁇ hig. After elapse of this period, both lamps are ready to fire.
- each switch off the lamp 1 can also be provided from turning aside ⁇ thereof that are alternately in this situation once again lamp 1 and lamp 2 off.
- the lamp according to the invention has four states, namely two on-states and two off states, wherein they in the egg ⁇ nen Off state is only halfway off and completely off in the other off state, in which one state is only halfway on and in the other on state is fully on.
- 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.
