[0052] The first connecting part 101 can be a bayonet connecting part or a screw connecting part, and the corresponding second connecting part 102 can also be a bayonet connecting part or a screw connecting part. In this case, the first connecting part 101 and the second connecting part 102 are both described in the form of screw connecting.

[0053] The upper end of the shell 10 has a screw connecting part 101 for screwing with the external lamp holder 21, and the lower end of the shell 10 has a screw lamp holder 102 for screwing with the screw lamp cap of the light bulb 22.

[0054] In the embodiment, the shell 10 comprises an upper shell 11 and a lower shell 12 which are detachably connected. Preferably, one of the upper shell 11 and the lower shell 12 has a buckle 111 and the other has a buckle slot 121, and the upper shell 11 and the lower shell 12 are connected, and the buckle 111 is fitted in the buckle slot 121. In order to quickly assemble the upper shell 11 and the lower shell 12, the embodiment designs a foolproof structure. Specifically, one of the upper shell 11 and the lower shell 12 has a foolproof guide 112 and the other has a foolproof guide slot 122, and the upper shell 11 and the lower shell 12 are connected, and the buckle 111 of the foolproof guide 112 is fitted in the foolproof guide slot 122.

[0055] The shell 10 is provided with a circuit board 31, and the circuit board 31 is provided with a control unit 311 and a dimmer 312. The control unit 311 is coupled between the screw connection part 101 and the screw lamp holder 102 to control the transmission power between the screw connection part 101 and the screw lamp holder 102 according to the dimming signal.

[0056] The upper shell 11 and the lower shell 12 are assembled to form a containing cavity, the circuit board 31 is located in the containing cavity, the screw connection part 101 is formed on the upper shell 11, and the screw lamp holder 102 is formed on the lower shell 12.

[0057] The lower end of the lower shell 12 is concavely provided with a groove 123, the groove 123 is provided with a metal conversion port cylinder 124 and an elastic conductive terminal 125, and the inner wall of the metal conversion port cylinder 124 is provided with an internal thread for screwing with the screw lamp cap of the bulb 22. The model of the internal thread is E26, and of course it can also be E27 or other models.

[0058] The metal conversion port cylinder 124 and the elastic conductive terminal 125 are respectively electrically connected to the control unit 311; the groove 123, the elastic conductive terminal 125, the metal conversion port cylinder 124 and the internal thread thereof together form the screw lamp holder 102.

[0059] In the embodiment, the upper end surface of the lower shell 12 is provided with a first through hole 126 and a second through hole 127 which respectively communicate with the groove 123;

[0060] The metal conversion port cylinder 124 is electrically connected to the control unit 311 by abutting the circuit board 31 through the first conductive connecting piece 128 passing through the first through hole 126, and the elastic conductive terminal 125 is electrically connected to the control unit 311 by abutting the circuit board 31 through the second conductive connecting piece 129 passing through the second through hole 127.

[0061] The shell 10 is provided with an adjustment knob 32 for controlling the dimmer 312, and the adjustment knob 32 is connected to the control unit 311 through the dimmer 312 to send a dimming signal to the control unit 311.

[0063] For example, when no operation of the relative zero knob 33 is performed, assuming that the adjustment range of the potentiometer is 0-30V and the minimum starting voltage of the bulb 22 is 15V, the user needs to rotate the adjustment knob 32 to half range to reach 15V. Conversely, after the operation of the relative zero knob 33 is performed, the user can slightly rotate a little to be greater than 15V, solving the problem of long adjustment time and low efficiency of the dimmer 312 and the adjustment knob 32. In the embodiment, the relative zero knob can be infinitely adjusted or gear adjusted.
