Abstract

The utility model relates to a lamp tube converter, comprising: a switching circuit, a transforming and rectifying circuit and a filtering circuit, wherein the switching circuit is connected with thetransforming and rectifying circuit that transforms AC and then rectifies AC into pulse DC; the switching circuit switches a power supply to an input end of the transforming and rectifying circuit ora power supply circuit inside the lamp tube; and the transforming and rectifying circuit is connected with the filtering circuit that changes the pulse DC into stable DC. When the lamp tube converteris arranged in a lamp tube (such as LED lamp tube or T5 lamp tube) and then the lamp tube is arranged in a lamp holder with an electronic stabilizer for use, a bidirectional silicon control rectifierof the switching circuit is conducted and the electronic switch is cut-off, so that the transforming and rectifying circuit acts with the filtering circuit to supply power to the lamp tube. When the lamp tube is arranged in a lamp holder with a conventional stabilizer or connected with commercial power for use, the bidirectional silicon control rectifier of the switching circuit is not conducted and the electronic switch is conducted, so that the transforming and rectifying circuit does not act with the filtering circuit to supply power to the lamp tube.

The specific embodiment

For reaching above-mentioned purpose and effect, technological means that the utility model adopted and structure thereof, drawing illustrates in detail that with regard to preferred embodiment of the present utility model its feature and function are as follows, understand fully in order to do profit.

See also shown in Figure 1ly, be circuit diagram of the present utility model, find out that by knowing shown in the figure fluorescent tube converter 1 of the present utility model is for comprising commutation circuit 11, transformation rectification circuit 12, filter circuit 13.This commutation circuit 11 is connected with carries out the transformation rectification circuit 12 that transformation is rectified into pulse direct current again with interchange, this commutation circuit 11 switches to the input of power supply circuits in this transformation rectification circuit 12 or the fluorescent tube 2 with power supply, and this transformation rectification circuit 12 is connected with the filter circuit 13 that pulse direct current is become steady direct current.

This commutation circuit 11 is for having bidirectional silicon-controlled rectifier (TRIAC) 111, and be connected with first resistance 112 and first electric capacity 113 between the grid of bidirectional silicon-controlled rectifier 111 and the second plate A2, and be connected with electronic switch 114 with the second plate A2 of bidirectional silicon-controlled rectifier 111, and electronic switch 114 is parallel with second electric capacity 115, and this electronic switch 114 is connected to the input of power supply circuits, and the positive pole in second electric capacity 115 is connected with second resistance 116 again.
