Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a dimmable LED bulb lamp. Background Art

[0002] Traditional LED lamps basically require an external speed controller to adjust the brightness of the lamp. Therefore, when purchasing a single LED lamp, it is impossible to adjust the brightness of the light, and the additional speed controller is difficult to assemble on any lamp holder with a speed control function. Based on this, LED bulbs with dimming functions are now available on the market. The corresponding dimming circuit is arranged on the driving board of the bulb, and the brightness of the light is adjusted by dialing. The bulb lamp of this structure usually requires an opening on the corresponding structural member (such as the side wall of the lamp cup), and one end of the dial switch is set in the opening to facilitate the dimming operation. In this structural design, the protruding dial switch hinders the aesthetics of the overall structure. At the same time, the opening set will also affect the integrity of the lamp body. External dust, water vapor, etc. can easily enter the lamp body through the opening, thereby affecting the electrical components in the lamp body, thereby affecting the overall service life.

[0028] In this specific embodiment, a rotation position locking mechanism is provided between the lamp holder connection part 301 and the bulb shell connection part 302. The rotation position locking mechanism can effectively prevent dimming from being misoperated.

[0029] In this specific embodiment, the lamp holder connecting part 301 and the bulb shell connecting part 302 can rotate relative to each other and can move up and down relatively. The rotation position locking mechanism includes an annular locking wall 32. The bulb shell connecting part 302 is provided with an annular locking wall 32 protruding in the direction of the lamp holder connecting part 301. The annular locking wall 32 extends into the inner cavity of the lamp holder connecting part 301. At least one locking protrusion 321 is protruding on the outer wall of the annular locking wall 32. A plurality of locking grooves 33 with lower openings matching the locking protrusions 321 are correspondingly recessed on the inner wall of the lamp holder connecting part 301. The plurality of locking grooves 33 are arranged at intervals. In the locked state, the lamp holder connecting part 301 and the bulb shell connecting part 302 are closed together so that the locking protrusions 321 are embedded in the corresponding locking grooves 33. When rotation dimming is required, the lamp holder connecting part 301 and the bulb shell connecting part 302 are pulled apart to release the locking grooves 33 from locking the locking protrusions 321.

[0036] In this specific embodiment, an installation space 8 for the annular locking wall 32 to be inserted and installed is provided between the positioning arm 71 and the inner wall of the inner cavity of the lamp holder connecting portion 301. It is ensured that there is enough space for the annular locking wall 32 to be embedded and installed when the lamp holder is closed.

[0037] In this specific embodiment, the bulb shell connection part 302 is a cylindrical structure with equal outer diameters from top to bottom, and the lower part of the lamp holder connection part 301 is a cylindrical body that matches the bulb shell connection part 302, so that the original external shape of the entire lamp can be maintained after the two are closed.
