Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.

Embodiment:

Referring to Fig. 1 and Fig. 2, this utility model provides a kind of technical scheme: a kind of light fixture with sterilizing function, including Lamp housing 1, the inside of described lamp housing 1 is installed with lamp tube cover 2, and lamp tube cover 2 connection has fluorescent tube 3, and the top of described lamp housing 1 is solid Dingan County is equipped with retainer ring 4 and supply lines 5, and described supply lines 5 connects NTC electric fuse 6 and switching switch 7, and NTC electric fuse 6 Connecting and have common mode inductance 8, described common mode inductance 8 connects full bridge rectifier 9, and full bridge rectifier 9 connection has PFC10, Described PFC10 connects inverse excitation type converter 11, and inverse excitation type converter 11 connection has case position protection circuit 12, feedback circuit 13 With Linear CCS 14, described Linear CCS 14 connects LED protection circuit 15, and Linear CCS 14 connection has fluorescent tube to supply Electricity end 16, described inverse excitation type converter 11 includes that the connection of high frequency transformer T, high frequency transformer T front end has positive source VCC and merit Rate switching tube VF, high frequency transformer T rear end connects the positive pole of diode VD, the negative pole of diode VD connect have electric capacity C positive pole, One end of resistance R and output Vout positive pole, the other end of electric capacity C negative pole and resistance R connects output Vout negative pole, described switching Switch 7 has three grades of conversion buttons, and three grades of conversion buttons include that weak level, middle rank and intensity level, described LED protection circuit 15 use surge to protect Protection circuit.

Operation principle of the present utility model: this has the light fixture of sterilizing function, first by 220V civil power by common mode inductance 8 For suppressing common mode current, then by full bridge rectifier 9, become DC voltage supply rear class, by rear class PFC10 electricity Road, it is achieved high power factor is mated, it is possible to realize suppressing self-oscillatory purpose, use inverse excitation type converter 11, uses PMW to adjust Mode processed, regulates output voltage by the dutycycle changing PMW ripple, reaches the purpose of burning voltage, because its efficiency is high, work Feature in a continuous mode is most widely used, and working stability, and modulation system is that fixing each switch periods internal power is opened Closing the time of pipe conducting, then realized the adjustment of voltage by regulating frequency, advantage is that quiescent dissipation is little, and ultraviolet is effective Disappear bacterium in realizing indoor virus killing, and by special protection circuit, protection circuit safety, be used for increasing the service life.
