[0033] like Figure 1-Figure 3 As shown, in this embodiment, the lamp panel 8 is connected to the lamp tube 3 by screws, the driver 10 is electrically connected to the LED lamp bead 9, the driver 10 adopts the Mean Well LPF-16D series, and can use three different methods to drive the LED current, and the driving methods are respectively a variable resistance driving method, a variable voltage driving method and a PWM driving method with adjustable duty cycle.
