The pen light tube 1 is provided with a battery 2 and a charging interface 19 located below the battery 2. A switch 3 is provided on the top of the pen light tube 1. A dual light source LED 11 is provided on the bottom of the pen light tube 1. A charging cover 7 for protecting the charging interface 19 is movably sleeved on the outside of the pen light tube 1.

[0026] Specifically, the dual-light source LED11 includes a white LED and a purple LED.

[0027] In this implementation plan, white LEDs can be used for illumination, while violet LEDs can be used for banknote verification and tracking.

[0028] Specifically, the pen light tube 1 has a circuit socket 8 located below the battery 2 inside. The circuit socket 8 has a circuit board 18 that is electrically connected to the battery 2 inside. The charging interface 19 is integrated on the circuit board 18. One end of the charging interface 19 extends to one side of the pen light tube 1 and is fitted with an interface sealing sleeve 191.

[0029] In this embodiment, the charging interface 19 adopts a waterproof interface with internal waterproof function. Together with the interface sealing sleeve 191 that seals the connection between the charging interface 19 and the pen lamp tube 1, the sealing and waterproof effect is further improved.

[0030] Specifically, a switch 3 is provided on the top of the pen lamp tube 1 via a switch plate retaining ring 6, and a switch fixing sleeve 16 is provided on the top of the switch 3.
