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. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a dimmable LED bulb lamp with a simple structure and a complete lamp body structure, which can effectively reduce the risk of external dust and water vapor entering the interior of the lamp body through the operating opening of the dial switch and ensure the service life of the lamp body.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

[0005] A dimmable LED bulb lamp comprises a lamp holder and a light-transmitting bulb shell, the lamp holder comprises a lamp holder body and a lamp cup, the lamp holder body is connected to the light-transmitting bulb shell through the lamp cup, an LED light-emitting device is arranged in the light-transmitting bulb shell, a driver is arranged in the lamp holder, the LED light-emitting device is electrically connected to the driver, a dimming module is arranged in the driver, the dimming module is adjusted by a dial switch, the dial switch is arranged in the lamp cup, an opening groove which passes through inside and outside is arranged on the side wall of the lamp cup, a regulating ring is rotatably mounted on the outside of the lamp cup, the regulating ring covers the opening groove, a toggle seat is convexly arranged on the inner wall of the regulating ring, a positioning groove is concavely arranged in the toggle seat, the toggle seat is located in the opening groove and can be toggled in the opening groove around the central axis of the lamp cup, and the outer toggle end of the dial switch is embedded in the positioning groove.

[0006] The lamp cup includes a lamp holder connecting part, an intermediate connecting part and a bulb shell connecting part which are arranged in sequence from top to bottom. The lamp holder body is fixedly connected to the lamp holder connecting part, the light-transmitting bulb shell is fixedly connected to the bulb shell connecting part, and the outer diameter of the intermediate connecting part increases gradually from top to bottom.

The regulating ring is rotatably mounted on the outside of the intermediate connecting part. The opening groove is arranged on the bulb shell connecting part. The lower part of the regulating ring is extended downward to provide an extension part. The extension part is mounted on the outside of the bulb shell connecting part and covers the opening groove. The toggle seat protrusion is arranged in the extension part. In conventional structural design, the width of the intermediate connecting part in the up and down directions is usually small, so the toggle switch is usually arranged in the bulb shell connecting part. Based on this, the opening groove is arranged on the bulb shell connecting part, and the opening groove is covered by the extension part. The regulating ring is mounted on the intermediate connecting part to facilitate the overall positioning and installation. The rotation of the regulating ring drives the extension part to rotate synchronously, so that the toggle seat drives the toggle switch to toggle the dial in the dimming module to achieve dimming.

[0008] The extension part completely covers the bulb shell connection part. The overall structural design is realized without changing the overall appearance of the bulb lamp.

[0009] The regulating ring is a ring body with an outer diameter gradually increasing from top to bottom and matched with the intermediate connection part. The regulating ring is rotatably sleeved and installed on the outside of the intermediate connection part. The opening groove is arranged on the intermediate connection part. The lower part of the toggle seat is extended downward and arranged in the bulb shell connection part. In conventional structural design, the width of the intermediate connection part in the vertical direction is usually small, so the dial switch is usually arranged in the bulb shell connection part. Based on this, the toggle seat is extended downward and arranged in the bulb shell connection part, which is convenient for the follow-up installation of the dial switch.

[0010] The outer diameter of the upper outer wall of the regulating ring increases gradually from top to bottom, the lower outer wall of the regulating ring is a cylindrical wall with the same outer diameter from top to bottom, the bulb shell connecting portion protrudes outward and is provided with a cylindrical convex wall with the same outer diameter from top to bottom, the upper end face of the cylindrical convex wall forms a limiting end face, the lower part of the regulating ring is located above the limiting end face, and the outer diameter of the cylindrical wall is equal to the outer diameter of the cylindrical convex wall. The limiting end face is used to limit the downward installation position of the regulating ring. At the same time, the above structural design ensures that even if the regulating ring is installed as an additional part, the external shape of the entire lamp will not appear particularly abrupt at the position where the regulating ring is installed, saving materials while maintaining the original external shape of the entire lamp.

[0011] A limiting rib is provided on the toggle seat at a position corresponding to the upper inner end surface of the opening slot, and the upper inner end surface of the opening slot abuts against the limiting rib, so as to limit the installation position of the regulating ring.

[0012] The outer wall surface of the regulating ring is provided with a plurality of anti-skid bumps, which increase the friction force and make the rotating operation more convenient.

[0013] A plurality of anti-skid protrusions are evenly arranged around the central axis of the regulating ring, which is neat and beautiful.
