Owing to there is no filament or electrode, can not be restricted because of the chemical property of filament or electrode material, thereby fundamentally reduce light decay, improved luminous efficiency and life-span.And Non-polarized lamp can start in moment, reach whole light output, can be because of producing light decay after multiple switching, so the life-span can reach tens thousand of hours.
But also because Non-polarized lamp does not have filament, work in electromagnetic coupled induction mode, starting voltage is high, can produce the unsuccessful phenomenon of once lighting a fire, make ballast spoilage very high.
Summary of the invention
The purpose of the present utility model is to overcome the deficiencies in the prior art, based on what improve on conventional electronic ballast single ignition trigger, improve the reliability that Non-polarized lamp starts, improve made electrodeless lamp tube consistency deviation, there is loss of ignition probability in the ballast of single starting ignition, repeatedly starting ignition electronic ballast for electrodeless lamp performance is improved, and the comprehensive utilization ratio of fluorescent tube improves.From electrical equipment angle improved plan, provide a kind of repeatedly electronic ballast of electrodeless lamp of igniting that has for Non-polarized lamp.
The present utility model is achieved through the following technical solutions:
A kind of repeatedly electronic ballast of electrodeless lamp of igniting, comprise PFC power-supplying circuit, accessory power supply power supply circuits, chip half-bridge drive circuit, half-bridge circuit, protective circuit and start-up circuit, it is characterized in that: PFC power-supplying circuit adopts PFC flyback transformer auxiliary winding power taking voltage stabilizing to obtain the low pressure 15V power mode of rear class chip needs, after chip normal ignition starts, 15V normally exports, loss of ignition circuit enters after guard mode, the impulse electricity of 15V power supply electrochemical capacitor under switch transformer PWM control action changes at 6-15V, voltage is lower than the operating voltage of chip, chip exits guard mode, chip starting ignition again when voltage 15V, technique scheme is further qualified, protective circuit repeatedly quits work circuit after igniting, utilize the magnetic ring coil loop of fluorescent tube to make front end PFC power supply stop starting, short-circuit protection quits work chip by protective circuit, makes ballast obtain safety and does not damage, technique scheme is further qualified, and number of starts accumulative total maximum times is 10 times, and this is to fluorescent tube just in case there is the situation safe precaution measure of slow gas leakage, technique scheme is further qualified, and protective circuit is protected restriction to high pressure, and overcurrent protection is connected to resistance in half-bridge drive circuit MOS, and sampling current signal is controlled chip, technique scheme is further qualified, and alternating voltage input range is 90-305V, has met the instructions for use of 100V-277V whole world most countries electrical network.
The utility model compared with prior art has following beneficial effect:
1. improve the reliability that Non-polarized lamp starts;
2. improve made electrodeless lamp tube consistency deviation;
3. improve the comprehensive utilization ratio of fluorescent tube.
