Detailed Description
The following provides a more detailed description of embodiments of the present invention with reference to the accompanying drawings:
as shown in fig. 1, the utility model discloses an uninterrupted power supply unit has been increased at current input unit and output unit, and its uninterrupted power supply unit can carry out incessant power supply to the HID lamp when the electric wire netting switches or the shake that falls promptly.
As shown in fig. 2, a specific structure diagram of a preferred embodiment of the present invention includes a filtering unit, an AC/DC unit, a charging module, an energy storage module DCL, a DC/DC module, an or logic gate circuit, a triggering unit, and a DC/AC unit; the filtering unit and the AC/DC unit form an input unit, the charging module, the energy storage module and the DC/DC module form an uninterruptible power supply unit, the triggering unit and the DC/AC unit form an output unit, or the logic gate circuit consists of two diodes, wherein the charging module is used for continuously charging the energy storage module, and when the power grid is switched or subjected to sudden drop and jitter, the DC/DC module converts the voltage output by the energy storage module into the voltage required by the HID lamp through the logic circuit and then continuously supplies power to the HID lamp.
As shown in fig. 3, the ballast device of the present invention includes: the filter circuit is a low-pass EMI circuit consisting of common-mode inductors L1, C1, C2, C3 and C4, and mainly has the functions of inhibiting Radio Frequency Interference (RFI) and electromagnetic wave interference (EMP) radiated by an electric appliance; the AC/DC circuit with APFC characteristic is composed of a rectifier bridge BR1, a chip U1(MC34262), an inductor L2, a MOS tube Q1 and a diode D1, and mainly has the functions of improving the system power factor (lambda), inhibiting higher harmonics (THD) and suppressing the peak ratio of lamp current; the DC/AC circuit and the trigger circuit are composed of a chip U2(IR2153), MOS transistors Q2 and Q3, a boost inductor T1 and a bidirectional trigger tube (SID1), and mainly function in starting and burning the HID lamp.

The added or logic gate module of the utility model consists of two diodes D2 and D3, and the function of the or logic gate module is to complete the conversion process at the moment of power failure of power grid switching or during transient drop jitter; the principle is that voltages applied to two diodes are unequal, at the moment, the diode with high applied voltage is conducted, the diode with low applied voltage is cut off, and once the diode with high applied voltage is cut off, the diode with low applied voltage is changed from cut-off to conduction. The utility model discloses an output of U1-APFC, the output of U4-DC/DC and the input of next stage U2-DC/AC circuit constitute an "OR" logical connection through diode D2 and diode D3.
Because the power grid switching (or power grid transient drop and shake) process is completed instantly, the time is extremely short (less than 1s), and the required energy storage is very limited; therefore, the invention can solve the problem of uninterrupted illumination of the HID lamp under the working condition by using the farad capacitor DCL with smaller capacity, not only can save cost, but also can charge instantly, and the service life of the farad capacitor is particularly long; the farad capacitance of different capacities can be selected according to different power of the HID lamp.
When the power failure of the grid switching is instantaneous or the grid switching is instable, the diode D2 is turned from on to off, the diode D3 is turned from off to on, the farad capacitor DCL is also turned from a charging state to a discharging state, and the voltage is converted into the voltage required by the HID lamp through the DC/DC unit formed by the U4(3843) to supply the HID lamp until the grid switching is completed or the instable jitter is stopped.
By adopting the device, the power supply system of the HID lamp has the UPS function, so that uninterrupted lighting can be realized in the true sense when power is switched by a power grid. Meanwhile, because the circuit does not have an ultrahigh voltage triggering link, irreversible damage to related electronic components and bulbs caused by ultrahigh voltage triggering can be completely eliminated. More importantly, the DCL has the characteristics of wide temperature range (-40-80 ℃), good instantaneous ultra-fast charging and large-current discharging characteristics, ultra-long service life (50 ten thousand charging/discharging) and no maintenance for life. It is due to these remarkable features that the technology and products of HID lamps uninterrupted lighting electronic ballasts are possible in important situations.
