Abstract
The utility model discloses an electrodeless lamp with a function of restart, and the electrodeless lamp comprises a filter rectification circuit, and an active PFC correction circuit which is connected with the output end of the filter rectification circuit. One output end of the active PFC correction circuit is connected with a power supply part, and the output end of the power supply part is connected with an IC control circuit. One output end of the IC control circuit is connected with a feedback circuit, and the other output end of the IC control circuit is connected with a drive circuit. The output end of the drive circuit and the output end of the feedback circuit are connected with the electrodeless lamp. The electrodeless lamp employs the active PFC correction circuit along with the power supply part and the feedback circuit for the power supply of the control circuit when the tube of the electrodeless lamp cannot illuminate normally, thereby enabling the active PFC correction circuit to output a signal again to the drive part for starting the tube of the electrodeless lamp, and carrying out the above operation till the tube of the electrodeless lamp is lightened. After the active PFC correction circuit is applied to the start circuit of an alternating-current electrodeless lamp, the output can be stabilized and the overall performance of the electrodeless lamp can be improved. Moreover, the active PFC correction circuit can work in a severe condition and has the value of development.
Description
Technical field
The utility model relates to a kind of Non-polarized lamp with repeated priming function.
Background technology
Non-polarized lamp belongs to the new-generation energy-saving product without filament, high light efficiency, long-life, high power factor, can be widely used in the place that family, factory building, office space, road, engineering construction building site, particularly fluorescent tube should not change.Because belonging to electrodeless startup, lights Non-polarized lamp, fluorescent tube is not existed because filament damages or electronic powder has been launched, and electronic powder sputter makes the problems such as fluorescent tube blackout and the phenomenon that causes whole lamp to scrap, the whole lamp life-span extends greatly, and operating frequency exceeds 200KHz, stroboscopic phenomenon is thoroughly eliminated.Non-polarized lamp is more having the outstanding advantages of this lamp aspect emergency light, solar lighting simultaneously, because Non-polarized lamp does not have filament, therefore in the application of AC power, can thoroughly avoid alternating electron energy-saving lamp tube blackout, the very short problem of lamp tube service life, control circuit of the prior art, at the severe situation cisco unity malfunction of environment, is exported unstable.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of while utilizing active PFC correction circuit collocation power pack, feedback circuit cannot normally light at electrodeless lamp tube, to control circuit power supply again, can again output signal to drive part and start electrodeless lamp tube, go round and begin again until the use Non-polarized lamp start-up performance circuit that electrodeless lamp tube is lighted.
The utility model is achieved through the following technical solutions: a kind of Non-polarized lamp with repeated priming function, it is characterized in that: comprise filter rectifier, and the active PFC correction circuit being connected with filter rectifier output, in the output of described active PFC correction circuit one end, be connected with power pack, described power pack output connects IC control circuit, described IC control circuit one end output connects feedback circuit, another output connects drive circuit, described drive circuit, feedback circuit output connects Non-polarized lamp, described active another output of PFC correction circuit is connected with drive circuit.
As preferred technical scheme, described IC control circuit comprises the first pin, the second pin, the 3rd pin, the 4th pin, the 5th pin, the 6th pin, the 7th pin, the 8th pin, the 9th pin, the tenth pin, the 11 pin, the 12 pin, the 13 pin and the 14 pin.
As preferred technical scheme, also comprise three terminal regulator, input storage capacitor C53 and voltage transformer L5.
The beneficial effects of the utility model are: when the utility model utilizes active PFC correction circuit collocation power pack, feedback circuit cannot normally light at electrodeless lamp tube, to control circuit power supply again, can again output signal to drive part and start electrodeless lamp tube, go round and begin again until electrodeless lamp tube is lighted, this circuit application can be stablized output to exchanging in Non-polarized lamp start-up circuit, improve Non-polarized lamp overall performance, in the situation that environment is severe, still can normally work, circuit possesses exploitation and is worth.
Accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the circuit block diagram of the utility model Non-polarized lamp repeated priming function;
Fig. 2 is the partial circuit figure of the utility model Non-polarized lamp repeated priming.
Embodiment
As depicted in figs. 1 and 2, a kind of Non-polarized lamp with repeated priming function of the utility model, it is characterized in that: comprise filter rectifier, and the active PFC correction circuit being connected with filter rectifier output, in the output of described active PFC correction circuit one end, be connected with power pack, described power pack output connects IC control circuit, described IC control circuit one end output connects feedback circuit, another output connects drive circuit, described drive circuit, feedback circuit output connects Non-polarized lamp, described active another output of PFC correction circuit is connected with drive circuit.
As preferred embodiment, described IC control circuit comprises the first pin, the second pin, the 3rd pin, the 4th pin, the 5th pin, the 6th pin, the 7th pin, the 8th pin, the 9th pin, the tenth pin, the 11 pin, the 12 pin, the 13 pin and the 14 pin.
In the present embodiment, also comprise three terminal regulator, input storage capacitor C53 and voltage transformer L5.
When electrodeless lamp tube cannot normally be lighted, feedback resistance R09 is by signal feedback to the tenth pin (current detecting input) in IC control circuit, and IC control circuit cuts out the 13 pin driver output letter, and IC control circuit stops output.Input storage capacitor C53 discharges by IC control circuit the 7th pin, R51, D61, until IC control circuit work threshold values.C10 (energy storage Shen appearance) passes through R12 ' electric discharge so simultaneously, active PFC correction circuit detects the upper voltage of C10 by R10, when C10 voltage is down to 430V when following, active PFC correction circuit is controlled L5 (voltage changer) and is powered to C10, also to 1.7815 power supplies, C53 is charged until the second pin of IC control circuit reaches normal working voltage simultaneously, IC control circuit is reworked, the 13 pin output drive signal on IC control circuit, drive circuit is lit a lamp again to electrodeless lamp tube.This process is gone round and begun again until electrodeless lamp tube is lighted normal work.
The beneficial effects of the utility model are: when the utility model utilizes active PFC correction circuit collocation power pack, feedback circuit cannot normally light at electrodeless lamp tube, to control circuit power supply again, can again output signal to drive part and start electrodeless lamp tube, go round and begin again until electrodeless lamp tube is lighted, this circuit application can be stablized output to exchanging in Non-polarized lamp start-up circuit, improve Non-polarized lamp overall performance, in the situation that environment is severe, still can normally work, circuit possesses exploitation and is worth.
The above, be only embodiment of the present utility model, but protection range of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
