The present invention relates to a power supply device for a sterilizing and insect-inducing lamp capable of easily mounting a lamp to a socket for power supply, and to a lamp device having the power supply device. The mosquito induction lamp using the mosquito induction lamp It is a lamp device for mosquito induction which separates the ballast from the lamp device for use and can easily mount the lamp to the power socket without considering the polarity and direction of the power source. (100), first and second UV (ultraviolet rays) LEDs 121 and 121 ', and a first and a second UV LEDs 121 and 121 And first and second contact terminals 131 and 131 'provided at both ends of the glass tube 100 so as not to distinguish between the polarity of the power supply and the direction of the lamp The first and second A power supply unit 130 for supplying power to the first and second UV LEDs 121 and 121 'through the sockets 130 and 130', the first and second sockets 130 and 130 ' Wherein the power supply comprises a first power supply terminal 150 for supplying power to the first and second UV LEDs 121 and 121 ', a first power supply terminal 150 for supplying power to the first and second UV LEDs 121 and 121' A second power supply terminal 160 for supplying power to the first power supply terminal 121 'and a second power supply terminal 160 for supplying power to the first power supply terminal 150' A first bridge circuit 170 is provided between the other end of the second UV LED 121 'and the second power supply terminal 160 and includes a second bridge circuit 180 having a third and a fourth output ), The first output section being connected to the third output section to supply power to the first and second UV LEDs (121, 121 ') regardless of the polarity, and the second output section 4 output section, and the first output section and the second output section A noise removing capacitor C is connected between the first and second output portions of the first bridge circuit
