Embodiment Construction
[0010] Generally, the analog switch of the present invention can be realized by IGBT or high-voltage MOS tube. If the LED driver uses a synchronous rectification circuit instead of diode rectification, then the analog switch box rectifier may use an integrated design. The detection circuit can be realized with a simple resistance sampling and comparison circuit.

The invention is applied to design and production of LED horizontal-moving type imitative daylight lamp, (namely, the LED horizontal-moving type imitative daylight lamp can be directly inserted into an existing lamp), can also be applied to the design of a special current module circuit and a drive chip, and provides a horizontal-moving type LED imitative daylight lamp with a safety function and an electric shock protection function.
Description
technical field [0001] The invention is used in the design and production of LED imitation fluorescent tubes, and also in the design of its special current module circuit and drive chip, and proposes a safety design for preventing electric shock in an open circuit state. Background technique [0002] Generally, LED fluorescent tubes with built-in power supply are used, and two ports of traditional fluorescent tubes are used, one of which is connected to a section of the AC power supply, and the other end is connected to the other end of the light source current through the ballast. Between the two ports is the input end of the built-in current, which is generally connected to a rectified power supply or a similar substitute, and is a low-impedance loop. [0003] If one end of the above-mentioned lamp tube is connected to an alternating current, and the human body touches the other end of the above-mentioned lamp tube through one of its parts (such as a finger), the human bod...
