[0035] The LED lamp assembly 2 includes a second shell 21 and an LED lamp 22, a switch plate 23 and a pot piece 24 arranged on the second shell 21. The second shell 21 is movably sleeved on the outside of the first shell 11 and is provided with a sleeve hole and an internal thread 200 located outside the sleeve hole. The switch plate 23 is electrically connected to the LED lamp 22. The pot piece 24 is arranged on the switch plate 23. A conductive spring 25 is provided between the pot piece 24 and the first conductive sheet.

[0036] The above-mentioned LED lamp assembly 2 realizes the lighting function through the LED lamp 22. The pot piece 24 can control the circuit switch and the power level according to the pressing situation, and then control the switch and brightness level of the LED lamp 22, such as no brightness, 10% brightness or 100% brightness; the second shell 21 can cooperate with the internal thread 200 of the first shell 11 through the internal thread 200, and adjust the position relative to the first shell 11 by rotating; the conductive spring 25 has the function of electrically connecting the pot piece 24 and the first conductive sheet, and the function of pushing the first shell 11 and the second shell 21 to separate when the internal and external threads 100 are disengaged.

[0037] Among them, the first shell 11 has a first position and a second position relative to the second shell 21.
