Abstract: The disclosure provides a multi-step shorting switch and an illumination device. The multi-step shorting switch includes a housing, wherein an upper surface or a side surface thereof is provided with an opening; a toggle device provided in the housing, wherein a top portion or a side surface, corresponding to the above opening, of the toggle device is provided with a toggle, the toggle passes through the opening, and a bottom portion of the toggle device is provided with a sliding contact member; and multiple contact terminals provided on a substrate, wherein the sliding contact member is configured to, in a sliding process caused by that the toggle is shifted, simultaneously contact at least two of the multiple contact terminals, to form multiple steps which are continuously in a turn-on status without a turn-off status. The multi-step shorting switch according to the disclosure solves problems in the related art that a switch circuit structure is complicated and a double-sided Printed Circuit Board (PCB) board is required, and has the beneficial effects that a structure is simple, and it may work with or without a single-sided PCB board.

Abstract: The present application discloses an illuminating device and a method for driving the illuminating device. The illuminating device comprises: an LED illuminating module; a mains supply operation module, comprising an LED driving unit; and a ballast operation module, comprising a simulation filament unit, a first detection unit, a second detection unit, a switch unit, a first start unit and a second start unit; wherein when the illuminating device is in a mains supply operation mode, the LED driving unit is used for driving the LED illuminating module; when the illuminating device is in a magnetic ballast operation mode, the first detection unit detects a voltage signal or frequency signal of the simulation filament unit and outputs a first detection signal, and after receiving the first detection signal, the first start unit enables the switch unit to be in a conducting state and drives the LED illuminating module; and when the illuminating device is in an electronic ballast operation mode, the second detection unit detects a voltage signal or frequency signal across both ends of the illuminating device and outputs a second detection signal, and after receiving the second detection signal, the second start unit enables the switch unit to be in a conducting state and drives the LED illuminating module.
