Definitions

  • the present invention relates to an electronic ballast for operating at least one lamp, in particular a gas discharge lamp, with a circuit preferably designed as a bridge circuit, via which at least one provided for connection to the lamp terminal with a supply voltage can be acted upon. Furthermore, the present invention relates to a lighting system with at least one preferably designed as a gas discharge lamp lamp and at least one light emitting diode.
  • Dimmable lamps in particular gas discharge lamps, have to spend a large part of the input power for the preheating of lamp filaments for operation in the dimmable range. If, for example, only minimal requirements are placed on a minimum illumination of an unused room in public buildings, the necessary preheating results in a comparatively high energy loss. It is an object of the present invention to reduce the energy loss of such lighting systems.
  • the object is achieved by an article according to the preamble of claim 1, which is characterized by the characterizing features of the claim. Furthermore, the object is achieved by an article according to claim 7.
  • a generic electronic ballast is characterized according to the invention by an LED driver circuit for operating at least one light emitting diode for illumination purposes from, wherein the LED driver circuit is arranged with the circuit together in a design.
  • the common design allows the compact arrangement of circuit and LED driver circuit to each other to achieve circuit advantages in the form of, for example, space and or component savings.
  • the common design can be realized by a realized for example by soldering direct connection of circuit boards of the circuit and the LED driver circuit.
  • Such an electronic ballast provides the conditions for the use of a single or multiple light-emitting diodes instead of operating a gas discharge lamp, preferably in the dimmed region, wherein in particular by the common design, a compact arrangement is achieved.
  • a common design for example, by a circuit comprising the circuit and the LED driver circuit potting compound or housing walls of an associated lamp housing are formed, resulting in a compact handling of the electronic ballast according to the invention.
  • the dimmable electronic ballast can be replaced by a static device to use the LED driver circuit instead of the dimmable circuit.
  • the LED driver circuit can of course also be used with dimmable electronic ballasts. For low levels of brightness, the LED driving circuit is more energy efficient to operate than the lamp-only circuit, which provides the necessary and no contribution to the generation of light preheat energy.
  • the arrangement of the LED driver circuit is preferably carried out with the circuit in a common housing, so that in particular known conventional housing can be reused and the possibility of retrofitting conventional Luminaires with LEDs is given.
  • the circuit and the LED driver circuit are arranged in particular in a common housing, which may in particular have connections for at least one lamp and one LED.
  • a lighting system with at least one preferably designed as a gas discharge lamp lamp and at least one light emitting diode, wherein the lighting system comprises an electronic ballast, which is provided for both the operation of the lamp and the LED.
  • this is a lamp with a single lamp and a single LED, which are operated together by an electronic ballast.
  • the LED can in this case be integrated together with the lamp, for example, in a single housing or in a building ceiling.
  • the system efficiency (lumens / watt) is better for a desired minimum illumination due to the LED used than for a gas discharge lamp, in dimmed operation.
  • the LED driver circuit and the circuit of the electronic ballast or of the lighting system which is preferably designed as a bridge circuit, can be switched separately via associated inputs in order to make the circuits of the device as separate as possible. However, it may also be advantageous to switch the two circuits via a common input, for example, depending on the input voltage.
  • a housing of an electronic ballast in this case preferably has at least one, better two connections for a light-emitting diode, via the LED driver circuit be supplied.
  • the latter is, for example, a flyback converter circuit, as in the prior art (for example, from the DE 2919905 A1 ) is known.
  • Such flyback converter circuits as well as other LED driver circuits can be arranged together with the circuit on a circuit board, in particular in a development of an electronic ballast according to the invention, whereby further space savings are achieved in the housing of the electronic ballast and the assembly is simplified during the manufacturing process.
  • the electronic ballast also includes an emergency light circuit, which can either be powered by a separate input and / or activated or can be activated via one of the other components of the electronic ballast.
  • an emergency light circuit may be designed such that it activates the light-emitting diode in the emergency light case instead of the lamp, so that a sufficient illumination for this case is achieved with simultaneous minimum energy use.
  • Eventually provided emergency power storage which provide sufficient energy regardless of an external energy source in the emergency light activation case, reach longer Uptime. Therefore, a circuit of the electronic ballast which can charge the emergency power storage is also particularly advantageous.
  • An emergency lighting phase which is activated by an emergency light circuit or is characterized by such, can be triggered, for example, in the event of a fault in the lamp or a circuit of the electronic ballast or by an external (emergency) signal.
  • the lighting system with a plurality of light emitting diodes, wherein a change in the light output by the light source system by switching a number of these light emitting diodes is possible.
  • This dimming by stepwise switching of light emitting diodes in combination with a fluorescent lamp allows for a selected number of light emitting diodes flexible design of a specific light output.
  • Particularly advantageous is furthermore a design of a lighting system with a motion detector, which is connected via a connection with the electronic ballast such that when a trigger signal of the motion detector, the lamp is turned on and the LEDs are either switched off or additionally switched or remain.
  • a design including a housing 1 in this embodiment includes a series of supply terminals for an LED driver circuit 2 and a fluorescent lamp circuit 3.
  • a connection 4 as a switched-supply connection for the circuit and a connection 5 as an unswitched-supply connection for the LED driver circuit enable independent operation of the circuits 2 and 3 and thus independent operation of LEDs 6 to be attached to light emitting diodes or a at the four poles of a terminal 7 mounted fluorescent lamp. Instead of using four poles (with cathode preheating), only two poles can be provided for operating a gas discharge lamp.
  • the terminals 4 and 5 share in this case a neutral terminal 20.
  • Both the LED driver circuit 2 and the circuit 3 have their own radio-protection filter, which are integrated into the respective circuits, instead of these can also be connected upstream.
  • a power factor correction circuit 8 which additionally includes its own radio-protection filter.
  • an unswitched supply voltage is boosted via the terminal 9 to an intermediate circuit voltage Uz. With this voltage, both the LED driver circuit 2 and the half-bridge circuit of the circuit 3 are operated.
  • the terminal 10 serves as a carrier voltage for turning on and off the circuit for the fluorescent lamp, for example, a voltage monitoring input of a corresponding half-bridge driver IC is connected via a voltage divider.
  • Port 10 again comprises a switchedsupply while port 9 comprises an unswitched-supply .
  • Fig. 3 is located in a housing 1 electronic ballast via a terminal 11 equipped with a battery charging system, which in addition to a power failure detection 12 has a circuit 13 for charging an emergency power storage.
  • This circuit 13 includes an EMC filter and is used to charge a battery.
  • the power failure detection 12 and the charging circuit 13 form an emergency light circuit. If a power failure is detected, the LED driver circuit is powered by means of the terminal 11 previously charged and not shown accumulator.
  • Such LED emergency lighting operation is as described energetically cheaper as a dimmed bulb operation, since no cathode heating is needed.
  • An inventive lighting system can thus make appropriate illumination of, for example, escape routes, emergency exits or collection points with appropriate directional characteristics of the associated LEDs.
  • at least one gas discharge lamp is to be operated via the connection 7.
  • the separate switching on and off of the LED operating part is made possible in particular for general lighting purposes.
  • An unswitched supply voltage is conducted via a radio protection filter to a PFC stage 8 and boosted to an intermediate circuit voltage Uz ( Fig. 4 ).
  • Uz intermediate circuit voltage
  • both the circuit 3 for the fluorescent lamp and the circuit 13 for charging the emergency power storage is connected.
  • the circuit 11 for power failure detection 12 or the battery charging unit 13 is connected via the connection 11.
  • the terminal 4 serves to provide a carrier voltage for switching on and off the circuit 3 for the gas discharge lamp or a plurality of gas discharge lamps and optionally for the LED driver circuit 2.
  • the charging an emergency power storage takes place continuously.
  • the operation of individual components is possible independently with appropriate design of the LED driver circuit.
  • FIG. 5 An inventive lighting system is in Fig. 5 shown. This includes an electronic ballast for the operation of two fluorescent lamps 14 and also two LEDs 16. The lamps 14 and the LEDs 16 are operated by one and the same electronic ballast, so that in the embodiment shown with compact fluorescent lamps a small-sized lighting system is realized.
  • a high-current LED 16 is arranged in a reflector 15 between two fluorescent lamps 14.
  • the LED 16 is located at a central point of the system.
  • the focus of the LED is thus, for example, in the center of the otherwise illuminated by the lamps 14 area, which is sufficient in an emergency light case.
  • Conventional reflectors 15 as well as conventional lamps can be used, wherein an electronic ballast according to the invention operates both bulbs 14 and 16 but does not require more space than previously required if the electronic ballast has identical dimensions or at least identical attachment points for mounting in such a bulb system.
  • the embodiment according to the Fig. 7 shows a high-current LED 16 at a central location of the lighting system, which in this simple case shown consists of a circular fluorescent lamp 14 and only one LED 16.
  • the illuminant system can enable a variable arrangement of the LEDs via, for example, displaceable plug-in contacts. Not only a central arrangement can improve illumination of certain areas.
  • Fig. 8 to 10 further embodiments of a lighting system according to the invention can be seen, in each case different fluorescent lamps 14 and a different number of high-current LEDs 16 are used. These may be separately or additionally switchable depending on the design of the electronic ballast and, for example, depending on a motion detector, not shown, illuminate a predetermined room situation. By a separate connectability of the LEDs 16, a quasi-dimmable operation of the system can also be achieved with a static device per se.
