Description

TECHNICAL FIELD

[0001] The utility model belongs to the strong pulse light therapeutic instrument field especially, it relates to a series lamp tube circuit for strong pulse light therapeutic instrument. BACKGROUND

[0002] In the strong pulse light therapeutic instrument field, the lamp tube circuit is the key component, and its performance directly affects the working effect and life of the therapeutic instrument. The traditional strong pulse light therapeutic instrument lamp tube circuit adopts the parallel connection mode. However, this parallel connection mode has many disadvantages.

[0003] In the parallel connection circuit, since each lamp tube is directly connected with the power supply, the electrical parameters of each lamp tube are difficult to be completely consistent, which leads to uneven current distribution during work. Some lamp tubes may bear excessively high current, so that the electrodes and other components inside the lamp tube are subjected to excessive impact and loss, and the service life of the lamp tube is greatly shortened.

[0004] At the same time, the parallel connection will produce a high peak current at the instant of lamp tube lighting. This is because multiple lamp tubes simultaneously draw current from the power supply, and the instantaneous large current impact puts strict requirements on the power supply system, which requires the power supply to have strong instantaneous power supply capacity and stability. Moreover, the excessively high peak current may also cause damage to other electronic components in the circuit, reduce the reliability and stability of the entire circuit system, and affect the long-term stable operation of the therapeutic instrument.
