[0034] Example 1

[0035] like Figures 1-4 As shown in the figure, the table lamp provided in Embodiment 1 of this utility model includes a lamp body 1 and a color temperature adjustment component 2.

[0036] The lamp body 1 includes a support member 11, a lamp cup 12, and a light source module 13; the lamp cup 12 is fixedly connected to the upper end of the support member 11, and the upper end of the lamp cup 12 is recessed to the bottom to provide a receiving groove 121; the light source module 13 covers the opening of the receiving groove 121, and the light source module 13 is rotatably connected to the upper end of the lamp cup 12.

[0037] The color temperature adjustment component 2 is disposed in the receiving groove 121. The color temperature adjustment component 2 and the light source module 13 can adjust the color temperature of the light source module 13 according to the rotation of the light source module 13.

[0038] Based on this technical solution, by placing the color temperature adjustment component 2 inside the receiving groove 121, the color temperature adjustment component 2 can be completely hidden inside the receiving groove 121 and not exposed on the lamp body 1 of the desk lamp. Compared with the traditional desk lamp method of exposing the color temperature adjustment switch on the lamp body 1, the desk lamp provided by this utility model can avoid the appearance coordination and aesthetic problems caused by the inconsistency between the switch color and material and the lamp body 1, thereby improving the product's competitiveness in terms of appearance and meeting consumers' pursuit of product aesthetics and high quality.

[0039] By employing a color temperature control component, the color temperature setting can be adjusted according to the rotation of the light source module 13. This allows users to easily adjust the color temperature of the desk lamp by rotating the light source module 13. Compared to traditional button or knob-based color temperature adjustment methods, this rotation-based adjustment method is more intuitive and convenient, providing users with a better user experience and meeting the color temperature requirements of light in different scenarios.

[0040] The light source module 13 includes a light-emitting element 131 and a circuit board 132. The light-emitting element 131 is rotatably connected to the upper end of the lamp cup 12 and covers the opening of the receiving groove 121. The circuit board 132 is fixedly connected to the lower end of the light-emitting element 131 and located within the receiving groove 121. The color temperature adjustment component 2 is fixedly connected to the light-emitting element 131 and can rotate with the rotation of the light-emitting element 131. The color temperature adjustment component 2 and the circuit board 132 are electrically connected. By placing the circuit board 132 within the receiving groove 121 and electrically connecting it to the color temperature adjustment component 2, the distance between the circuit connection of the circuit board 132 and the color temperature adjustment component 2 can be shortened, which helps to reduce signal transmission loss and interference, improve the stability and reliability of the circuit, and thus help improve the stability and reliability of the desk lamp.

[0041] In this first embodiment, the color temperature adjustment component 2 is a potentiometer. A potentiometer is a commonly used electronic component with three pins, which can change parameters such as voltage and current in a circuit by adjusting its resistance.

[0042] The working principle of the desk lamp provided in Embodiment 1 of this utility model is as follows: When the light source module 13 rotates, the potentiometer rotates with the light source module 13. The potentiometer changes the position of its contact point by rotating to output different electrical signals. The circuit board 132 controls the light-emitting body 131 to produce color temperature changes according to the electrical signals received from the potentiometer, thereby realizing the color temperature adjustment of the light-emitting body 131.

[0043] The support member 11 includes a base 111 and a support rod 112. The support rod is fixedly connected to the base 111, and the lamp cup 12 is fixedly connected to the upper end of the support rod 112.

[0044] The support rod 112 includes a first round rod segment 1121 and a second round rod segment 1122. The first round rod segment 1121 is fixedly connected to the base 111, and the second round rod segment 1122 is fixedly connected to the upper end of the first round rod segment 1121. The lamp cup 12 is fixedly connected to the upper end of the second round rod segment 1122.

[0045] The central axis of the first round rod segment 1121 coincides with the central axis of the second round rod segment 1122, and the radius of the first round rod segment 1121 is larger than the radius of the second round rod segment 1122. This design, with the first round rod segment 1121 having a larger radius than the second round rod segment 1122 and their central axes coinciding, conforms to mechanical principles and enhances the overall stability of the desk lamp. In some embodiments, the second round rod segment 1122 support rod 112 is telescopic or bendable, allowing users to easily adjust the height and angle of the lamp cup 12 according to actual usage scenarios and their own needs to achieve optimal lighting effects. By using the smaller-radius second round rod segment 1122 to connect the lamp cup 12, the weight of the upper structure is reduced while ensuring stable support for the lamp cup 12. This makes adjusting the height and angle of the lamp cup 12 easier and less strenuous, improving user convenience and allowing for faster adjustment of the desk lamp to a suitable lighting position, thus enhancing the user experience.

[0046] Along the axial direction of the support rod 112, the length of the first round rod segment 1121 is shorter than the length of the second round rod segment 1122. The longer second round rod segment 1122 allows the lamp holder 12 to be installed at a higher position, expanding the lighting coverage of the desk lamp without changing the angle of the lamp holder 12. For example, on a large office desk or reading area, the light can be more evenly distributed on a larger work surface, avoiding blind spots caused by the lamp holder 12 being too low, thus improving the practicality of the desk lamp and meeting the user's need for large-area lighting in different scenarios. The shorter first round rod segment 1121 is closer to the base 111, and the connection between the first round rod segment 1121 and the base 111 is more stable. When adjusting the angle of the lamp holder 12, since the operating point (the second round rod segment 1122) is far from the fixed end (the connection point between the first round rod segment 1121 and the base 111), the lever arm is relatively long. Users only need to apply a small force to easily adjust the angle of the lamp holder 12, making the operation more flexible and convenient, improving the user's adjustment experience during use, and reducing operational fatigue.

[0047] The desk lamp provided in Embodiment 1 of this utility model also includes a lampshade 3, which is connected to the upper end of the light source module 13. The lampshade 3, connected to the upper end of the light source module 13, provides physical protection for the light source module 13. The lampshade 3 effectively prevents dust, moisture, and other external impurities from entering the interior of the light source module 13, helping to extend the service life of the light source module 13, reducing the product's failure rate, and ensuring the desk lamp can operate stably for a long time.

[0048] In this first embodiment, the central axis of the light source module 13 is the first axis 10, and the light source module 13 rotates around the first axis 10, that is, the light source module 13 achieves color temperature adjustment through rotation.

[0049] The light source module 13 can be rotatably connected to the lamp cup 12 through shaft hole fitting or bearing connection to realize the rotation of the light source module 13 around its own central axis.

[0050] Example 2

[0051] See Figures 5-6 Unlike Embodiment 1, the desk lamp provided in Embodiment 2 also includes a rotation damper 4. The light source module 13 is rotatably connected to the lamp holder 12 via the rotation damper 4. The rotation damper 4 provides stable damping force during the rotation of the light source module 13, making the rotation of the light source module 13 smoother and more stable. This avoids sudden color temperature changes caused by excessively fast or abrupt adjustments to the rotation speed of the light source module 13, creating a more comfortable and gentle color temperature adjustment experience for the user. At the same time, the rotation damper 4 can also buffer the impact and inertial forces generated when the light source module 13 rotates, reducing the direct impact on the adjustment components. This helps to reduce the risk of damage to the adjustment components due to frequent stress and extends the service life of the adjustment components.

[0052] In this second embodiment, the light source module 13 revolves around the second axis 20 of the rotation damper 4.

[0053] Specifically, the rotation damper 4 includes a mounting base 41, a mounting plate 42, a rotating shaft 43, a damping sleeve 44, and a connecting seat 45. The mounting base 41 is fixedly connected to the lamp cup 12. The mounting plate 42 is connected to the upper end of the mounting base 41. The mounting plate 42 has a first through hole, the central axis of which is a second axis 20. The damping sleeve 44 is connected to the mounting plate 42 and has a second through hole. The rotating shaft 43 passes through the first and second through holes and can rotate around the second axis 20. The connecting seat 45 is fixed to the rotating shaft 43 and located on the side of the damping sleeve 44 away from the mounting plate 42. The color temperature adjustment component 2 is fixedly connected to the rotating shaft 43 and located on the side of the mounting plate 42 away from the damping sleeve 44. The damping sleeve 44 provides suitable damping force for the rotation of the rotating shaft 43, allowing the user to feel uniform and stable resistance feedback when rotating the light source module 13. This unique tactile feel makes the adjustment process smoother and more natural, avoiding the negative impact on user experience caused by overly easy or overly sluggish rotation. It enhances the product's quality and user satisfaction.

[0054] Specifically, in this second embodiment, the light-emitting body 131 is fixedly connected to the connecting seat 45, that is, the color temperature adjustment component 2 is fixedly connected to the light-emitting body 131 through the rotating shaft 43, so that the color temperature adjustment component 2 can rotate with the light-emitting body 131.

[0055] In this second embodiment, the second axis 20 is perpendicular to the first axis 10. That is, the light source module 13 achieves color temperature adjustment by swinging back and forth. The swing amplitude of the light source module 13 can be increased by setting a corresponding notch at the upper end of the lamp cup 12 or the lower end of the light source 131 to avoid the back and forth swinging action of the light source module 13.

[0056] In some other embodiments, the second axis 20 and the first axis 10 may be parallel or intersecting.

[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
