Definitions
- the invention relates to a use of an electronic ballast for a lamp that is designed for Wendeldauervortropic. It also relates to a method for controlling such an electronic ballast. Finally, the invention is still directed to a DALI control device for controlling at least one electronic ballast for a luminaire via a DALI bus.
- DALI means "Digital Addressable Lightening Interface", ie digitally addressable lighting interface.
- the Wendeldauervor heater differs from the short preheating of the lamp filaments. While the brief preheating only takes up to 2 seconds, the coil duration pre-heating is intended to preheat the lamp filaments in the minute range without the lamp being operated during this period.
- Coil heaters (known by Osram under the term "permanent-pre-heat-mode") have been used to prepare for the fastest possible ignition, a typical application being so-called dynamic RGB applications, where the abbreviation stands for red-green-blue. So for applications in which colored light is used.
- Typical electronic ballasts ignite fluorescent lamps sufficiently well down to temperatures of about -20 ° C. Below these temperatures can Fluorescent lamps are not always ignited safely. This leads to limitations in the use of fluorescent lamps in cold environments, for example in cold stores or in outdoor lighting in northern regions. So far, one manages to heat the fluorescent lamps as a whole with the help of eg incandescent lamps, which are integrated into the closed luminaire. The incandescent lamps heat the luminaire by approx. 5 to 10 ° C, which may be sufficient to ensure reliable ignition of the fluorescent lamp.
- the object is achieved by a use of an electronic ballast according to claim 1, a method according to claim 2 and a DALI control device according to claim 4.
- an electronic ballast for a luminaire which is designed for Wendeldauervorloomung used in an environment in which the temperature is -20 ° C or less.
- the invention is based on the realization that not necessarily the fluorescent lamp to normal temperature (20 C 0) must be heated in order to ensure reliable igniter fertil. It is sufficient if the lamp or the discharge space of the lamp is brought to a sufficiently high temperature, in particular to a temperature of -20 ° C., by the helical preheating.
- the control is carried out according to the invention as follows: At a first predetermined time, the coil duration preheating of the electronic ballast is activated, and at a second predetermined time the ignition of the lamp takes place after activation. Preference is given to directly transition from the Wendeldauervorsammlungung to ignite the lamp, ie the Wendeldauervorloomung so finished at the second predetermined time.
- the second predetermined time will be the one that is fixed, that is, a target time for turning on the lamp.
- the first predetermined time should then be 10 to 20 minutes before the second predetermined time.
- a typical value would be a time of 15 minutes before the second predetermined time, because previous electronic ballasts built by OSRAM with coil duration pre-heating design automatically terminate the coil duration pre-heating after exactly 15 minutes.
- the DALI control device for controlling at least one electronic ballast for a luminaire via a DALI bus is designed to deliver control commands to the (respective) electronic ballast on the basis of information about the electronic ballast to be controlled, the information being stored in entries in a memory are provided.
- An entry indicates the information as to whether the electronic ballast is designed for coil-duration pre-heating.
- another entry is provided which gives the information as to whether the electronic ballast is in an environment where the temperature is at most -20 ° C.
- the DALI control unit thus has the prerequisites for the control of the electronic ballast which is designed for coil duration pre-heating, if this is used in an environment in which the temperature is -20 ° C. or less.
- the DALI control unit is preferably designed to carry out the method according to the invention for activation.
- FIG. 1 schematically illustrates a control system used in the invention when performing a first step of the method according to the invention and illustrated
- Fig. 2 illustrates the control system of Fig. 1 in carrying out a second step of the method according to the invention.
- a luminaire designated as a whole by 10 comprises an electronic ballast 12 and a lamp 14.
- Electronic ballast 12 and lamp 14 are located in an environment 16 shown symbolically by dashed lines, in which a temperature of less than -20 ° C prevails; shown is a thermometer 18, on which a temperature of -25 ° C is displayed.
- the electronic ballast 12 is connected via a DALI bus 20 with a DALI control unit 22.
- the DALI controller 22 and the DALI bus 20 may be out of the cold zone as shown but may also be provided in the cold environment.
- the DALI control unit 22 comprises a memory 24, in which symbolically three entries 1 to 3 are shown.
- a first entry is via the electronic ballast 12, the information as to whether this is designed for Wendeldauervor heater. This is the case here.
- a second entry indicates that the electronic ballast 12 (or the entire lamp 10) is in an environment 16 where the temperature is less than -20 ° C.
- a third entry indicates a time when the lamp 14 is to be turned on.
- the DALI controller 22 includes a clock 26.
- the lamp 14 is to be turned on at 5 o'clock.
- the filaments 28 of the lamp must be preheated by the electronic ballast 12 for a quarter of an hour. Accordingly, the DALI control unit at quarter to five (see clock on clock 26 in Fig. 1) from a control command via the DALI bus 20 from that the Wendeldauervor heater is activated.
- the lamp filaments 28 are now preheated for a quarter of an hour. The temperature of the lamp 14 then exceeds -2O 0 C, so that it can be safely ignited.
- the DALI controller 22 issues a command that the ignition of the lamp 14 is to be activated.
- the electronic ballast 12 receives this command, and the ignition of the lamp 14 takes place.
- the activation of the coil duration pre-heating and the subsequent activation of the ignition does not necessarily have to take place as a function of an entry in the memory 24. Rather, the Wendeldauervor heater and subsequently the ignition can also be initiated by actuation of switches by a user. The user should then know or be notified via an indication that the lamp 14 is not being fired immediately, but that a coil duration pre-heater is being initiated.
