Embodiment 1

[0016] The piezoelectric ceramic electronic ballast of this embodiment is shown in Figure 1, the AC / AC sine wave power module (TWA100-XX-XX series) is used as an AC power supply with a predetermined frequency output, and the two input terminals A and B of the piezoelectric ceramic Respectively connect the two output ends of the AC / AC sine wave power module, the resonant starter circuit composed of the inductance L and the capacitor CJ connected in series between the two output ends L1 and L2 of the piezoelectric ceramics, and the two ends of the capacitor CJ are respectively led out to the gas discharge lamps The first lamp terminal (M) and the second lamp terminal (N) are connected to the gas discharge bulb HID.

[0017] When working, after the AC power is input to the two input terminals of the piezoelectric ceramic, the two output terminals are boosted and output, and the series resonance between the inductance and the capacitor device is excited, which causes a further boos...

Embodiment 2

[0020] The piezoelectric ceramic electronic ballast of this embodiment is shown in Figure 2, which is basically the same as that of Embodiment 1, the difference is that the power supply adopts DC, and after passing through the DC / AC module (TWA100-XX-XX series), the output meets the voltage requirement. The high-frequency AC power of the electric ceramic is provided to the input terminals A-B of the first-stage piezoelectric ceramic ZH. Its use effects and advantages are basically the same, and will not be repeated here.

Embodiment 3

[0022] The piezoelectric ceramic electronic ballast of this embodiment is shown in Figure 3. The two input terminals A-B of the first-stage piezoelectric ceramic ZH are respectively connected to the DC / AC switching power supply module (TWM100-XX-XX series) as the AC power supply. Two output terminals OUT, this module can convert the 12V (or 24V, 36V, 48V) power supply of the low-voltage DC rechargeable battery EIN input +IN and -IN into an AC sine wave output. Among the two output terminals of the first-stage piezoelectric ceramic ZH, the first output terminal L1 is connected to the first output terminal H2 of the second-stage piezoelectric ceramic ZJ through the series inductor L and capacitor CJ, and the first output terminal L1 is also connected to the first output terminal H2 of the second-stage piezoelectric ceramic ZJ through the inductor L Then connect the first input terminal C of the second-stage piezoelectric ceramic ZJ through the trigger tube TVS, the breakover volt...

Abstract

The invention relates to an electronic ballast of piezoelectric ceramic, which belongs to the technical field of switch power supply. The electronic ballast comprises piezoelectric ceramic; the two input terminals of piezoelectric ceramic are connected with the AC supply of pre-set frequency; a resonance starting circuit composed of serially-connected inductance elements and capacitance elements is connected between the two output ends of the piezoelectric ceramic; the two ends of the capacitance elements are respectively connected with a first lamp connecting terminal (M) and a second connecting terminal (N) of a gas discharge lamp and lantern. The invention adopts a feasible technical proposal where the piezoelectric ceramic is used for achieving the functions of the ballast; the piezoelectric ceramic not only has the advantages of high reliability and high temperature resistance, but also effectively decreases the pre-stage and last stage electromagnetic interference by an electrical isolation between the pre-stage drive and the last stage load, Furthermore, the whole electronic ballast is ultra-thin, ultra-light and very cost-effective.

Description

technical field [0001] The invention relates to an electronic ballast, in particular to an improvement of the electronic ballast, which belongs to the technical field of switching power supply. Background technique [0002] The ballast is an indispensable starting device for common gas discharge lamps. Electronic ballasts have changed the shortcomings of traditional magnetic ballasts, which are bulky, prone to noise, high power consumption, low overall light efficiency, and low energy saving, and have become a rapidly developing energy-saving alternative product. Electronic ballasts not only have a wide variety, but also have been improved in an endless stream. For example, the Chinese invention patent with application number 200610045836.9 and titled "Electronic Ballast for High Intensity Discharge Lamp" discloses an electronic ballast for high intensity discharge lamp. It consists of anti-interference passive filter, bridge rectifier circuit, passive power factor correct...
