Definitions

  • the invention relates to a method and an apparatus for controlling and controlling a helical heating for lamps, in particular fluorescent lamps.
  • An inventive method is designed for controlling and controlling a filament heater for lamps.
  • the filament heater for fluorescent lamps can be controlled and controlled by the method according to the invention.
  • an operating parameter of at least one first coil is detected.
  • This first helix is arranged in a control loop.
  • a manipulated variable is determined as a function of the detected operating parameter.
  • the first coil is regulated.
  • a control of at least a second helix is carried out as a function of this manipulated variable, wherein the second helix is arranged outside the control loop.
  • an operating parameter is detected only by a single helix and from the obtained information of the operating parameter a manipulated variable is determined, which is used on the one hand to control the first helix and to control another helix by means of this manipulated variable.
  • a manipulated variable is determined, which is used on the one hand to control the first helix and to control another helix by means of this manipulated variable.
  • the detection of the operating parameter and the determination of the manipulated variable is performed independently of the number of filaments and the lamps electrically connected to the filaments.
  • the heating of the filaments in particular the controlled heating of the filaments, is independent of the number of connected filaments or the connected lamps.
  • the number of entrained coils thus has no influence on the control. It can thus be achieved that, by means of the information of an operating parameter of only one single helix, a manipulated variable is determined by means of which the heating of a relatively large number of helices, which are all connected outside the control loop, is controlled.
  • the heating power of this controlled coil is detected as the operating parameter of the controlled coil. It may further be provided that the specific manipulated variable is transmitted via a first actuator to the first coil and a second actuator to the second coil. In an advantageous embodiment, the detected operating parameter of the first coil is transmitted to a heating controller and determines the manipulated variable by means of the heating controller.
  • a device for controlling and controlling a filament heater for a lamp, in particular for a fluorescent lamp, has a control loop.
  • a first coil In this control loop, a first coil, means for detecting an operating parameter of this first coil and means for generating a manipulated variable for controlling this first coil, connected.
  • the device according to the invention comprises a second coil, which is arranged outside the control loop or is connected outside the control loop into the device. This second helix can be controlled by means of the control variable determined by the control loop.
  • the control loop comprises a detection member for detecting an operating parameter of the first coil and a first actuator, wherein the first actuator and the detection member are electrically connected to the first coil.
  • a heating controller is connected in the control loop between the detection member and the first actuator.
  • the at least second coil is electrically connected to the first or a second actuator. It can also be provided that the heating controller is electrically connected to the first and second actuator.
  • the device for controlling and controlling a helical heating or an advantageous embodiment thereof as a ballast for lamps is used.
  • Particularly suitable is the use as a dimmable ballast for lamps, especially for fluorescent lamps.
  • FIGURE shows a device according to the invention for controlling and controlling a filament heater for fluorescent lamps, which is used as a ballast for fluorescent lamps.
  • FIG. 1 shows a first coil W1, which serves to heat a lamp, which in the exemplary embodiment is designed as a fluorescent lamp L1.
  • the helix W 1 is electrically connected at a first end to the fluorescent lamp L1.
  • the first coil W1 is electrically connected at a second end to a first actuator S1.
  • a detection element E is shown in FIG.
  • the detection element E is designed in the exemplary embodiment such that an operating parameter of the first coil W1 can be detected.
  • the detection element E is electrically connected to a heating controller H.
  • the heating controller H is electrically connected in the exemplary embodiment with the actuator S1.
  • the control loop is formed by the first coil W1, the detection element E, the heating controller H and the first actuator S1 as the essential elements.
  • a second coil W2 is electrically connected to the fluorescent lamp L1 at a first end and to a second actuator S2 at a second end. Further, coils W3 to Wn are electrically connected to the second actuator S2 and lamps L2 to Ln. In the embodiment, an electrical connection between the heating controller H and the second actuator S2 is also formed.
  • the second actuator S2 is not present and the coils W2 to Wn are electrically connected to the first actuator S1. It should be noted that the coils W2 to Wn are arranged outside the control loop or are connected outside the control loop into the device according to the invention, as shown in FIG.
  • the detection element E is electrically connected to another coil, for example to the coil W2.
  • the circuit arrangement of the device would have to be designed such that, instead of the first coil W1, the second coil W2 is arranged in the control loop.
  • two or more coils are electrically connected to the detection element E and are connected in a corresponding control loop.
  • the operating parameters of two or more coils are detected and determined from the corresponding information of these operating parameters of the plurality of coils a corresponding control variable by the heating controller H.
  • the actuator S1 and the actuator S2 are formed in the embodiment as voltage sources with duty cycle change.
  • An operating parameter of the first coil W1 which in the exemplary embodiment is the heating power of this first coil W1 is detected by means of the detection element E.
  • the detected heating power is transmitted as controlled variable R to the heating controller H.
  • the heating controller H determines, as a function of the control variable R obtained, a manipulated variable SG, which is transmitted to the first actuator S1 and to the second actuator S2.
  • the manipulated variable SG is a signal which includes a duty cycle as information.
  • the duty cycle to the actuators S1 and S2 can be changed by means of the transmitted manipulated variable SG.
  • this manipulated variable SG By transmitting this manipulated variable SG to the first actuator S1 is a duty cycle change and due to the duty cycle of the voltage source or the first actuator S1, a control of the first helix W1 is performed.
  • a change in this duty cycle is also achieved there. Accordingly, the coils W2 to Wn are controlled by means of the second actuator S2.
  • the principle according to the invention is independent of the nature of the resonant circuit (s) or independent of the type of discharge current generation.
  • the inventive device of a mixed-controlled / controlled filament heating is preferably used as a dimmable ballast for fluorescent lamps.
