[0020] In the above scheme, the magnetically controlled switch 10 includes a dimming ring 101 arranged on the top surface of the upper cover 1, and the bottom surface of the dimming ring 101 is provided with an annular groove 1011, a magnet mounting groove 1012, and a spring mounting cavity 1013. A damping ring 102 is arranged in the annular groove 1011, a magnet 103 is arranged in the magnet mounting groove 1012, and a compression spring 104 and a steel ball 105 are arranged in the spring mounting cavity 1013. The top surface of the upper cover 1 is recessed downward to form a dimming ring mounting groove 1a, and the dimming ring mounting groove 1a is provided with a mounting hole. 1a1 and four spherical gear slots 1a2 arranged around the mounting hole 1a1, the bottom of the dimming ring 101 is threadedly connected after a screw 106 located below the upper cover 1 passes through the mounting hole 1a1, a gasket 107 is arranged between the screw 106 and the bottom surface of the upper cover 1, and when the dimming ring 101 is installed in the dimming ring mounting slot 1a, the side surface of one side extends out of the upper cover 1, and when the dimming ring 101 rotates, the steel ball 105 is squeezed by the compression spring 104 and is respectively positioned in the four spherical gear slots 1a2 to form a locking gear, a low gear, a middle gear and a high gear in sequence.

[0021] The circuit board 9 is provided with an indicator light holder 11 and a light guide plug 12 , the indicator light holder 11 is provided with a plurality of power indicator lights 111 , and the top surface of the upper cover 1 is provided with indicator holes 1 b corresponding to the power indicator lights 111 one by one.

[0022] Specifically, there are four power indicator lights 111, and each light corresponds to 25% of the remaining total power. When the power is turned on, the power indicator lights 111 will light up to indicate the battery charging status (each LED lights up about 25%). When only one power indicator light 111 is lit, you should stop using the product and charge it. When charging, the power indicator lights 111 indicate the battery charging status and will flash the highest power indicator light 111 to indicate that charging is in progress. After charging is complete, all four power indicator lights 111 will light up steadily.

[0023] In addition, a lens sealing ring 13 is provided between the lens 8 and the body 3 .

[0027] In the present invention, the power switch 92 corresponds to two states: on and off, and the magnetic control switch 10 corresponds to four states: lock, low, middle and high.

[0028] When working, the power is turned on after the power switch 92 is pressed, and the lamp bead board 7 directly displays the corresponding brightness when in low, medium and high gears.

[0029] In the locked position, after the power switch 92 is pressed, the power indicator light 111 works, but the lamp bead board 7 will not light up.

[0030] In the off state, long press the power switch 92 for 2 seconds to directly switch to low brightness, and then control the magnetic control switch 10 to select different gears.

[0031] In the working state, long press the power switch 92 for 2 seconds to enter the super bright mode, and return to the gear selected by the magnetic control switch 10 after 30 seconds.

[0032] In the non-locking position, double-clicking the power switch 92 activates the strobe mode, regardless of whether the product is on or off.

[0033] Under normal lighting conditions, the light will change gradually when shifting gears, but there will be no gradual change when flashing.

[0034] The above description is only a preferred implementation mode of the utility model, and does not impose any form of limitation on the utility model. Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the utility model still falls within the scope of the technical solution of the utility model.
