摘要:
Die Erfindung betrifft ein Betriebsverfahren für eine Lichtanlage und eine Lichtanlage, bei denen ein Bereitschaftsbefehl vorgesehen ist, auf den hin ein Vorschaltgerät eine Entladungslampe in der Weise betreibt, dass es die Elektroden bei nicht brennender Entladungslampe weiterheizt, so dass ein Steuergerät durch einen Einschaltbefehl die Entladungslampe ohne Verzögerung durch eine Vorheizzeit wieder zünden kann.

The invention relates to a flat spotlight (1) with a closed, gas-filled discharge vessel (2) and enclosing band-shaped electrodes separated from the discharge by a dielectric layer. The discharge vessel (2) consists of at least one base plate (5) and one cover plate (6) which are assembled by soldering (8) so as to be gastight, and optionally, also by means of an additional frame (7) placed between the cover and base plate. In addition, the band-shaped internal electrodes (3, 4) verge into passages (10, 11), and these passages verge into external power leads (12, 13) in such a way that the internal electrodes (3, 4), the passages (10, 11) and the external power leads (12, 13) are respectively conceived as functionally different sections of structures (3, 10, 12; 4, 11, 13) of the printed conductor type on the cathodes and/or anodes. At least the anodes (4) are respectively coated with a dielectric layer (17). The passages (10, 11) are, in addition, optionally covered by the soldering (8) so as to be gastight.

The invention relates to a dielectric barrier discharge lamp with a fluorescent mixture and improved colour reproduction. The fluorescent mixture comprises at least the fluorescent components: A) cerium-activated yttrium aluminate (Y3AI5O12:Ce) and B) europium-activated barium magnesium aluminate (BaMgAI10O17:Eu). To further improve the colour reproduction and to match the emission spectrum to the film sensitivity the fluorescent mixture optionally comprises the additional fluorescent components: C) cerium- and manganese-activated gadolinium magnesium zinc pentaborate (Gd(Zn,Mg)B5O10:(Ce, Mn)) and/or the fluorescent component D) europium-activated strontium aluminate (Sr4AI14O25:Eu).

The invention relates to a circuit which comprises a voltage-controlled transistor (T4) and is used to switch the same. Said circuit is embodied in such a way that the connection of a first transistor (T1) triggered by a control signal causes a first current to flow through a series connection (R4, T1) and starts to reload a control gate of the voltage-controlled transistor (T4). The first current passing through the series connection (R4, T1) causes a first potential shift at the connection node (V1). Said first potential shift switches on the second transistor (T2), thus causing a second current to flow through the contact gap of the second transistor (T2) into the control gate of the first transistor (T1), amplifying the first current. The increasing reloading of the control gate of the voltage-controlled transistor (T4) causes a second potential shift at the connection node (V1). The second transistor (T2) is switched off by said second potential shift, while the first transistor (T1) remains switched on and the voltage-controlled transistor (T4) is maintained in the new switching state thereof.
