Specifically, in the embodiment, the light source 30 is an LED filament lamp light source, the dimming module 21 is a structure for adjusting color temperature, brightness or color in the prior art, that is, by dialing the dial 211, the dimming operation of the dimming module 21 is realized, and the dimming module 21 and the light source driving board 20 with the dimming module 21 are prior art, which will not be described in detail here.

[0028] The lamp shell 10 comprises a lamp cap connecting shell 11, a knob ring 12 and a fixing ring 13. The knob ring 12 is rotatably assembled on the inner side of the lamp cap connecting shell 11. The fixing ring 13 is arranged on the inner side of the knob ring 12 and is fixedly connected with the lamp cap connecting shell 11. The knob ring 12 is limited between the lamp cap connecting shell 11 and the fixing ring 13. Specifically, the knob ring 12 extends radially inwardly and has an abutting boss 121. The fixing ring 13 abuts against the abutting boss 121 to limit the assembly of the knob ring 12. In this way, the knob ring 12 is limited by the clamping of the lamp cap connecting shell 11 and the fixing ring 13, so that the knob ring 12 can only rotate circumferentially. The light source driving board 20 is fixedly inserted on the inner side of the fixing ring 13 to fix the light source driving board 20. The knob 211 of the light adjusting module 21 is matched with the knob ring 12 to realize the adjustment switching with the rotation of the knob ring 12. The lamp cap 50 is assembled on the lamp cap connecting shell 11 and is electrically connected with the light source driving board 20.

[0029] The lamp shell 10 is divided into the lamp cap connecting shell 11, the knob ring 12 and the fixing ring 13. The knob ring 12 is rotatably assembled by the clamping cooperation of the lamp cap connecting shell 11 and the fixing ring 13. The sealing effect is good, and the components in the lamp body can be effectively protected. At the same time, the light adjusting switching of the light adjusting module 21 is realized by the rotation of the knob ring 12. The operation is simple, and the connection structure is stable and not easy to be damaged.

[0030] Further, in the embodiment, the inner side of the fixing ring 13 is formed with two oppositely arranged clamping grooves 131. The clamping grooves 131 are provided with convex flaps 132. The light source driving board 20 is provided with a limiting gap 22. The light source driving board 20 is inserted into the clamping grooves 131 of the fixing ring 13.

[0032] Further, in the embodiment, the inner side wall of the knob ring 12 is provided with two spaced apart blocking walls 124, and the knob 211 of the dimming module 21 is fitted between the two blocking walls 124. In this way, when the knob ring 12 rotates, the knob 211 of the dimming module 21 is driven to rotate by the blocking walls 124, thereby realizing dimming operation. The structure is simple, and the blocking walls 124 are not directly connected with the knob 211, so as not to be stuck. Of course, in other embodiments, the fitting mode of the knob ring and the knob 211 of the dimming module 21 is not limited to this.

[0033] Further, the fixing ring 13 is formed with a limiting window 133, and the blocking walls 124 of the knob ring 12 are located in the limiting window 133, thereby being limited to move within the range of the limiting window 133, so as to prevent the knob ring 12 from rotating excessively and damaging the dimming module 21.

[0034] Further, the bottom surface of the fixing ring 13 in contact with the abutting step 121 of the knob ring 12 is formed with a plurality of first arc-shaped protrusions 134 distributed at intervals. In the embodiment, the first arc-shaped protrusions 134 cover the bottom surface of the fixing ring 13. The first arc-shaped protrusions 134 are arranged to make the fixing ring 13 form linear contact with the knob ring 12, thereby effectively reducing the frictional force.

[0035] Similarly, the bottom surface of the knob ring 12 in contact with the lamp holder connecting shell 11 is formed with a plurality of second arc-shaped protrusions 123 distributed at intervals; the knob ring 12 contacts the lamp holder connecting shell 11 through the second arc-shaped protrusions 123, thereby effectively reducing the frictional force, so that the knob ring 12 rotates more smoothly and the hand feeling is improved.

[0036] Further, the lamp holder 50 can adopt a standard size lamp holder structure in the prior art, such as E14 type, E26 type and E27 type, etc.

[0037] Further, the lamp shade 40 is fixed on the knob ring 12 and rotates together with the knob ring. Of course, in other embodiments, the lamp shade 40 can also be fixed on the lamp holder connecting shell 11 or the fixing ring 13.

[0038] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, it should be understood by those skilled in the art that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all the changes are within the protection scope of the utility model.
