Definitions
- the invention relates to the field of dimmable control gear for light sources, specifically to dimmable control gear for the combined operation of gas discharge lamps and semiconductor light sources.
- the invention is based on dimmable operating devices for the combined operation of gas discharge lamps and semiconductor light sources according to the preamble of the main claim. So far, in light fixtures, which also use semiconductor light sources such as light-emitting diodes in addition to the gas discharge lamps that have been used for a long time, every light source has been considered as such. With dimmable lights, each light source is dimmable, but both light sources are not considered as one unit.
- US Pat. No. 7,052,187 B1 discloses a luminaire in which LEDs are used in addition to compact fluorescent lamps.
- the light sources can be dimmed independently.
- a common dimming mechanism using both types of light sources is not described here.
- fluorescent lamps can be dimmed with the appropriate technical effort up to 1% of the nominal light, but the efficiency drops significantly at these low dimming positions. Also, the color of the emitted light can change, as at very low Performs the lamp cools strongly and gives the argon charge over the mercury discharge more weight.
- the operating device contains circuits that can operate both lamps dimmed.
- an analog bus herein a 1-LOV-bus is used as a digital interface
- the DALI protocol is used.
- the di ⁇ gitale interface knows light control commands and light scenarios that are stored in the control gear ⁇ to. If a signal is input to this input, the operating device controls the light output of both light ⁇ sources according to the entered dimming level.
- FIG. 1 Schematic representation of a fiction, modern ⁇ hybrid system.
- FIG. 2 Graph illustrating the transition from the semiconductor light sources to the gas discharge lamps.
- FIG. 3 Graph illustrating another takeover criterion: the specific efficiency of the light sources.
- FIG. 1 shows a schematic connection diagram of an operating device according to the invention.
- the device features from ⁇ transitions for gas discharge lamps and semiconductor light sources.
- the gas discharge lamps are preferably compact fluorescent lamps, and the semiconductor light sources may be, for example, white LEDs or OLEDs. It is of course also possible to use only one gas discharge lamp and one semiconductor light source or one gas discharge lamp and a plurality of semiconductor light sources .
- a light control interface In addition to the mains voltage input, there is an input for a light control interface. This can be a digital or an analog interface. But it is also possible to program the interface to one or the other light control protocol. This has the pre ⁇ part of a widest possible availability of operation ⁇ device.
- the two different light sources should be placed in the luminaire so that the light distribution of both bulbs is similar. Only then can the luminaire be dimmed within a wide range without visible optical deviations.
- Fig. 2 shows a diagram illustrating the principle of the procedure during the transition from the LEDs to the gas- discharge lamps ⁇ illustrated.
- the dimming position of a light control signal is indicated via the total brightness.
- Both light source types operated by the device are controlled via a light control signal.
- the two curves for the semiconductor light sources and the gas discharge lamps run in large areas on the light control signal, ie that in all areas except the dimming range of 3% -10% each of the light output of Halbleitlichtquel ⁇ len or the gas discharge lamps exactly follow the default value of the light control signal.
- the light control signal At the bottom and top ends the light control signal, as there is no correlation There is more between signal and brightness.
- both types of light source contribute to system light output.
- the light sources are each dimmed so that the total light intensity corresponds to the default value of the light control signal.
- the LEDs or OLEDs illuminate ⁇ rich in the lower Dimmbe, for example from 1 to 10% s3. From a dimming position of 3%, the gas discharge lamps are switched on. At the time of lamp ignition, the light output of the LEDs is suddenly reduced at the same time in order not to change the total light intensity of the luminaire. To compensate for the short light ⁇ lightning of the gas discharge lamp, which it emits on ignition, as well as possible, it would also be conceivable, the LEDs for the moment of lamp ignition th quitegesschal-. In the range between 3% and 10% both lamps are successively in the Light power up. At 10% dimming, the LEDs are turned off and the power of the gas discharge lamp is suddenly increased to maintain the amount of light emitted. From there, the gas discharge lamp is up to its rated capacity he raufgedimmt ⁇ .
- the transition between the two lamp categories can be visible despite the same brightness. This is especially the case if the lamp length ⁇ re time was operated at low dimmer, which greatly dimmed the gas discharge lamp or completely bringsschal ⁇ tet. Then the lamp cools down and changes its color or is cooled down at the start so far that it gives a slightly different color than in the nominal light mode.
- the operating device has outputs for different colored light emitting diodes.
- a map may begarspei ⁇ chert, which describes the dependence of the temperature of the gas discharge lamp ⁇ on the dimming setting, the time and the color locus.
- the semiconductor light sources are turned on at low dimming settings in de ⁇ nen, is the operating unit then the locus of different brightly colored semiconductor light sources on the color point of the gas discharge lamp.
- the semiconductor light sources may be organized in groups, so that a plurality of semiconductor light sources are provided for each color.
- Another possibility is to use a sensor for the Ge ⁇ felhellmaschine and the color locus, and to control the lamps so that the values for the A ⁇ zelhellmaschineen, for the total luminance and the two color locations of the different light sources measured and can be regulated.
- the Mes ⁇ solutions must then be carried out only if the measured lamp is turned on. This is relatively easy in the lower dimming ⁇ area, since the light sources are pulsed on and controlled it is therefore always points in time in which only the measured lamps illuminated. If the activation does not result in a suitable time, then the control of the operating device for a measurement can switch off all non-metered lamps. Since this period is very short, it can not be perceived by the human eye.
