Lamp tube switching circuit

Abstract

The invention discloses a lamp tube switching circuit which comprises a first lamp tube incoming end and a second lamp tube incoming end which are used to connect the two ends of the lamp tube and a power port which is used to connect with a power supply. The lamp tube switching circuit also comprises a switch module which is connected between the power port and the first lamp tube incoming end, wherein the switch module comprises at least two switch elements and a keypress module with at least two buttons, and each button is used to switch one type of lamp tube. A corresponding relation is set and stored in advance, which is used to define the correspondence of the at least two buttons and the at least two switch elements; a logic control unit responses a pressing trigger of the button in the keypress module, determines the connection status of the switch element corresponding to the triggered button in the keypress module according to the relation and controls the at least two switch elements to switch to the corresponding connection status, thus a suitable circuit for the lamp tube type corresponding to the triggered button can be formed in order to lighten the lamp tube.

Description

technical field [0001] The invention relates to a lamp tube switching circuit, in particular to a switching circuit which can be connected to various types of lamp tubes. Background technique [0002] With the development of LED lighting technology, LED fluorescent lamps are being widely used. However, the structure of the traditional lamp holder for installing ordinary fluorescent lamp tubes does not match that of LED fluorescent lamps. When installing LED fluorescent lamp tubes, the original fluorescent lamp holders need to be replaced, and the lighting circuit of the fluorescent lamp tubes needs to be completely changed. tear down. Furthermore, since the input types of various LED lamp tubes on the market are not the same, different lighting circuits need to be set according to the types of the lamp tubes, so different LED lamp tubes cannot share lamp sockets. Therefore, users cannot freely replace ordinary fluorescent lamp tubes and various LED fluorescent lamp tubes w...

However, the structure of the traditional lamp holder for installing ordinary fluorescent lamp tubes does not match that of LED fluorescent lamps. When installing LED fluorescent lamp tubes, the original fluorescent lamp holders need to be replaced, and the lighting circuit of the fluorescent lamp tubes needs to be completely changed. tear down

Furthermore, since the input types of various LED lamp tubes on the market are not the same, it is necessary to set up different lighting circuits according to the type of lamp tubes, so different LED lamp tubes cannot share lamp sockets.

Therefore, users cannot freely replace ordinary fluorescent lamp tubes and various LED fluorescent lamp tubes with different input types according to needs, which is inconvenient to use and cannot better meet the needs of consumers.
