[0002] Traditional LED light sources often emit only a single brightness or color of light. To enable dimming or color temperature adjustment, a dimming or color temperature switch needs to be installed on the lamp body. Currently, most commercially available LED lamps with dimming or color temperature adjustment functions have corresponding dimming or color temperature circuits installed on a driver board inside the lamp body. The brightness or color of the light is adjusted by changing the switch's setting. This type of LED lamp typically requires an opening in a structural component (such as the side wall of the lamp reflector), with one end of the switch located within this opening for dimming operation. This design, with the switch protruding, detracts from the overall aesthetics. Furthermore, the opening affects the integrity of the lamp body, allowing external dust and moisture to easily enter and damage the electrical components, thus affecting the overall lifespan. Summary of the Invention

[0018] Figure 6 for Figure 5 A partial breakdown diagram. Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] As shown in the figure, an LED lamp with adjustable brightness or color temperature includes a lamp head 1 and a light-transmitting bulb 2. A driver 3 is installed inside the lamp head 1, and an LED light-emitting device (not shown in the figure) is installed inside the light-transmitting bulb 2. The LED light-emitting device is electrically connected to the driver 3. A dimming or color temperature adjustment module (not shown in the figure) is installed inside the driver 3. The dimming or color temperature adjustment module is controlled by a switch 4. An adjustment mechanism is provided between the lamp head 1 and the switch 4. The adjustment mechanism includes an adjustment element 5 rotatably mounted on the lamp head 1. The adjustment element 5 is connected to the switch 4 through a toggle element 6. By rotating the adjustment element 5, the toggle element 6 drives the switch 4 to change the setting to achieve brightness or color temperature adjustment.

[0021] In this specific embodiment, the toggle member 6 includes a connecting seat 61 for connecting to the switch 4, and a rack and pinion connecting part 62 is provided on the connecting seat 61. The adjusting member 5 includes a rotation operating part 51 disposed outside the lamp head 1 and a rotation driving part 52 disposed inside the lamp head 1. The rotation operating part 51 and the rotation driving part 52 are coaxially arranged. The rotation driving part 52 is a gear that meshes with the rack and pinion connecting part 62, and the teeth of the gear mesh with the teeth on the rack and pinion connecting part 62. By adopting a gear-rack meshing design, the rotational motion of the adjusting member 5 is converted into the linear motion of the toggle member 6. The transmission ratio is stable, ensuring the accuracy and consistency of the switch 4's gear switching. Through the gear and rack meshing, the user can perceive a clear gear change when rotating the adjusting member 5, improving the intuitiveness of operation, and avoiding accidental dimming or color temperature adjustment caused by accidental touch. The meshing transmission structure has low wear, can maintain stability after long-term use, and requires no lubrication, resulting in low maintenance requirements, making it suitable for high-frequency adjustment applications.

[0022] In this specific embodiment, the switch 4 includes a switch base 41 and a toggle part 42 that is protruding upwards and can be toggled on the switch base 41. The connecting seat 61 has two guide sliding arms 611, and the switch base 41 is disposed between the two guide sliding arms 611. The two guide sliding arms 611 are respectively attached to the two opposite end faces of the switch base 41. The connecting seat 61 is provided with a positioning groove 612 for the toggle part 42 to be embedded and installed. The toggle part 42 is embedded upwards in the positioning groove 612. The switch base 41 is limited by the two guide sliding arms 611 to ensure that it moves along a fixed trajectory when toggled, avoiding deviation or jamming, and improving the accuracy and reliability of adjustment. The design of the toggle part 42 being embedded in the positioning groove 612 simplifies the assembly process, realizes the quick alignment and installation of the switch 4 and the toggle part 6, and reduces the complexity of production. The fit between the switch base 41 and the guide sliding arms 611 saves internal space and is suitable for the integrated design of a small area inside the lamp holder 1.

[0023] In this specific embodiment, the rotating operating part 51 is provided with a plurality of anti-slip protrusions 511. This increases friction and makes the rotating operation more convenient.

[0024] In this specific embodiment, multiple anti-slip protrusions 511 are evenly distributed around the central axis of the rotating operating part 51, resulting in a neat and aesthetically pleasing appearance.

[0025] In this specific embodiment, an insulating inner support 7 is provided inside the lamp holder 1, and the driver 3 and switch 4 are both disposed inside the insulating inner support 7. The insulating inner support 7 is used to isolate the driver 3 and switch 4 from direct contact with the metal lamp holder 1, preventing the risk of short circuit or leakage, and meeting safety requirements; the driver 3 and switch 4 are centrally fixed inside the insulating inner support 7 to prevent internal components from shaking or shifting, and to improve the overall structural stability.

[0026] In this specific embodiment, the insulating inner support 7 has a through-cavity 71, in which the driver 3 and switch 4 are both disposed. The top opening of the insulating inner support 7 has an annular limiting wall 72. The adjusting member 5 has a mounting wall 53 for extending into the lamp holder 1. A positioning protrusion 531 protrudes from the mounting wall 53. The mounting wall 53 passes through the opening at the top of the lamp holder 1 and enters the inner cavity 71 through the central opening of the annular limiting wall 72. The positioning protrusion 531 is located below the annular limiting wall 72. This design is simple and allows for stable, rotatable mounting of the adjusting member 5 on the lamp holder 1.

[0027] In this specific embodiment, both the adjusting member 5 and the toggle member 6 are made of plastic.
