Abstract
In the luminous efficiency of gas-discharge lamps, in particular compact fluorescent lamps, a temperature-compensating element (3) which controls the lamp current in function of temperature is incorporated in the ignition device. This type of temperature-compensating element (3) advantageously consists of a current-limiting reactor in the form of a coil (9) with a central core (10). The core (10) is acted on by a spring (11) and a bimetallic spring (12) in such a way that its depth of penetration into the coil (9) is a function of temperature. The resultant variation in the induction of the current-limiting reactor (L) causes the lamp current to vary in function of temperature in such a way that the gas-discharge lamp is optimally operated independently of temperature.

Fig. 1 represents the calcspar of the control device of gaseous discharge lamp 1.This control device comprises that the electronic circuit 2(that is used for electric ballast wherein relates generally to a kind of high frequency (HF) generator), and have temperature compensating element 3 to connect with it.As gaseous discharge lamp such, in order to start gas discharge, have capacitor 4 in parallel with fluorescent tube.
Fig. 2 shows the preferred embodiment of electronic circuit 2.Supply voltage 220V+10% for example wherein, 50-60 is conspicuous to be added on terminal 5 and 6.Fuse Si guarantees when electronic circuit 2 breaks down, when particularly being short-circuited, and can not produce the harm that causes because of big electric current.Diode D1, D2, D3 and D4 and the first capacitor C1 and the second capacitor C2 be as rectifier, and choke DR and the 3rd capacitor C3 are as smooth network and link the positive output end of rectifier.By first resistance R 1, when the start-oscillation circuit that the 4th capacitor C4 and the 5th diode D5 and diac semiconductor element (Diac) DIA form guarantees to insert supply voltage on terminal 5 and 6 by first transformer on the one side (Strom Ubertrager) coil TR1 A, the base resistance R2 of series connection with it, the first transistor T1 and emitter resistance R3 and the second transformer coil TR1 B on its opposite side, the base resistance R4 of series connection with it, the high-frequency oscillating circuits that transistor seconds T2 and emitter resistance R5 form is in oscillatory regime.Two additional diodes D6 and D7 and be used for stablizing the frequency of high-frequency oscillating circuits by the RC network that the 6th resistance R 6 and the 6th capacitor C6 form.Gaseous discharge lamp 1(is a compact fluorescent lamp herein) connect with high-frequency oscillating circuits through the 5th capacitor C5 and the 3rd transformer coil TR1 C, wherein temperature compensating element 3(this sentence its form of responding to temperature variant current-limiting reactor coil L and occur) also be connected on therebetween, and capacitor 4 is connected on the gas discharge tube in parallel or exactly is connected between electrode 7 and 8.
Play preferable arrangement temperature compensating element 3, the temperature variant current-limiting reactor coil of its induction (impedance) L by Fig. 3 and Fig. 4 are a kind of as can be seen.Clearly, relate to coil 9 herein, be provided with movably (preferably ferrite core 10) unshakable in one's determination in the central.Side at iron core is added to elastic force on the iron core through spring 11 on the axis direction of coil 9, and a thermally sensitive spring (preferably bimetallic spring 12) props up iron core so that ferrite core 10 enters the how much relevant with ambient temperature of coil 9 on opposite side.Here the preferred mode that adds the power of two springs 11 and 12 should be able to be implemented in predetermined lowest temperature stream reactance coil L and present predetermined impedance, this impedance should meet calculated value, and current-limiting reactor coil L must present this resistance value, and the electric current that obtains of gaseous discharge lamp 1 should be able to just in time obtain its maximum light output under its service conditions by this.
When ambient temperature was lower than rated temperature, ferrite core 10 went out to serve from coil 9 by the effect of spring 11 again, will cause that for this reason the impedance of current-limiting reactor coil L reduces, so that the electric current of lamp increased.Therefore the loss relevant with temperature at the light output facet of gaseous discharge lamp 1 is compensated by the electric current that increases lamp.
In contrast, when ambient temperature is higher than rated temperature, ferrite core 10 by the power of bimetallic spring 12 effect and enter coil 9, so that the induction that increases current-limiting reactor coil L.Therefore the electric current of lamp descends.By this, can offset the increase of the light output of the gaseous discharge lamp 1 that causes owing to too high temperature.Can find out significantly that from Fig. 3 and Fig. 4 coil 9 and two springs 11 and 12 of band ferrite core 10 all are contained in the housing 13.
