Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a light adjustment device and lighting equipment. Background Technology

[0002] Most lighting devices currently on the market still use a traditional push-button design to adjust the lighting mode. This design typically requires users to apply vertical pressure, switching between different light levels or modes through varying degrees of pressure. However, in actual use, this vertical pressure method has significant drawbacks. Because the pressure applied is difficult to control precisely, it easily becomes unstable, sometimes too strong and sometimes too weak. This instability directly leads to unclear adjustment levels, preventing users from accurately switching to their desired lighting mode, thus affecting the normal operation of various product functions and reducing user satisfaction. Utility Model Content

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies. This utility model provides a light adjustment device and lighting equipment.

[0004] This utility model provides the following technical solution: A lighting adjustment device includes a pressure sensor, a roller bracket, and an adjustment wheel.

[0005] The pressure sensor is installed inside the main body of the lighting equipment; the roller bracket is fixedly installed on the main body of the lighting equipment; the adjusting wheel is hinged to the roller bracket via a rotating shaft, and the adjusting wheel has an adjusting section corresponding to the pressure sensor on its side near the pressure sensor; the adjusting wheel rotates relative to the roller bracket, allowing different parts of the adjusting section to press against the sensing surface of the pressure sensor; the roller bracket has a positioning part corresponding to the adjusting wheel, and the roller bracket can limit the relative position of the adjusting wheel and the roller bracket through the positioning part.

[0006] As a further improvement to the above technical solution, the side of the adjusting wheel near the pressure sensor is an arc-shaped convex surface, which is used to form the adjusting section.

[0007] As a further improvement to the above technical solution, the starting end and the ending end of the adjustment section are the closest end and the farthest end, respectively; the distance between the axis of the rotating shaft and the side of the adjustment wheel where the adjustment section is located gradually increases from the closest end to the farthest end.

[0008] As a further improvement to the above technical solution, the roller bracket is provided with a positioning groove on the side near the adjusting wheel. The positioning groove is used to form a positioning part. Multiple positioning protrusions corresponding to the positioning groove are evenly distributed on the adjusting section along the circumferential direction of the rotating shaft. The positioning protrusions can be inserted into the positioning groove.

[0009] As a further improvement to the above technical solution, the side opposite to the adjustment section of the adjustment wheel is a toggle section, and at least part of the toggle section protrudes from the side of the main body.

[0010] As a further improvement to the above technical solution, a limiting surface is provided at the intersection of the farthest end of the toggle section and the adjustment section. The limiting surface is set away from the pressure sensor. Rotating the adjustment wheel drives the nearest end of the adjustment wheel to move closer to the sensing surface of the pressure sensor, so that the limiting surface can abut against the roller bracket.

[0011] As a further improvement to the above technical solution, the toggle segment is an arc-shaped surface that protrudes away from the pressure sensor.

[0012] As a further improvement to the above technical solution, the side surface of the adjusting wheel where the toggle section is located has anti-slip texture.

[0013] As a further improvement to the above technical solution, the main body is provided with a protective shell corresponding to the adjusting wheel. The protective shell covers the outside of the adjusting wheel, and the protective shell has a toggle opening corresponding to the shape of the toggle section.

[0014] The present invention also provides a lighting device, including a main body and a light adjustment device as described above, wherein the light adjustment device is mounted on the main body.

[0015] Compared with related technologies, the beneficial effects of this utility model are: The lighting adjustment device provided by this utility model aims to bring users a more convenient, accurate and reliable lighting adjustment experience.

[0016] Adjusting the brightness or mode of the lighting equipment is incredibly simple. Users merely need to turn the adjusting wheel on the roller bracket, causing it to rotate relative to the bracket. As the wheel rotates, the adjusting section on it moves accordingly. Different positions of the adjusting section apply varying degrees of pressure to the sensing surface of the pressure sensor within the lighting equipment. The pressure sensor detects these pressure changes. Once it receives different pressure levels, it quickly and accurately converts this pressure information into different pressure signals and promptly sends them to the lighting control unit within the equipment. Upon receiving these different pressure signals, the lighting control unit, according to a preset program and logic, rapidly switches between different lighting brightness levels or modes, instantly creating a lighting environment that meets the user's needs.

[0017] After the adjustment is completed, the positioning part on the roller bracket limits the position of the adjustment wheel. This ensures the adjustment wheel remains stable, providing a continuous and stable pressure signal to the pressure sensor. Consequently, the lighting equipment can maintain stable operation at the user-set brightness or mode, avoiding problems such as flickering or unexpected mode switching caused by unstable pressure signals.

[0018] As can be seen from the complete adjustment process described above, this invention utilizes the rotation of the adjusting wheel to provide different levels of pressure to the pressure sensor, thereby adjusting the lighting mode of the lighting equipment. Compared with the traditional press-type adjustment structure, this adjustment method has significant advantages. In the traditional press-type adjustment structure, users often find it difficult to accurately grasp the pressing force and depth, resulting in unclear adjustment levels and easy errors during operation. However, the adjustment method of this invention allows users to more intuitively feel the changes in the adjustment level's travel during the rotation of the adjusting wheel, thus gaining a clearer and more accurate understanding of each level during the adjustment process. This makes operation more convenient and allows users to easily achieve precise adjustments, greatly improving the convenience and accuracy of operation and effectively ensuring the user experience of the lighting equipment.

[0019] Furthermore, the limiting mechanism for the adjusting wheel further enhances the stability and reliability of the continuous pressing pressure provided by the adjusting wheel to the pressure sensor. Regardless of how the user moves the lighting equipment or experiences minor external disturbances, the adjusting wheel remains stable, continuously providing a consistent pressure signal to the pressure sensor. This ensures that after the user adjusts the light, the lighting equipment consistently outputs the required light, providing reliable illumination for the user.

[0029] Combination Figure 1 , Figure 2 The embodiment of the present invention shown provides a light adjustment device, including a pressure sensor 200, a roller bracket 300, and an adjustment wheel 400.

[0030] The pressure sensor 200 is installed inside the main body 100 of the lighting equipment; the roller bracket 300 is fixedly installed on the main body 100 of the lighting equipment; the adjusting wheel 400 is hinged to the roller bracket 300 via a rotating shaft 420, and the adjusting wheel 400 has an adjusting section 410 corresponding to the pressure sensor 200 on its side near the pressure sensor 200; the adjusting wheel 400 rotates relative to the roller bracket 300, which allows different parts of the adjusting section 410 to press against the sensing surface of the pressure sensor 200, thereby providing different pressures to the sensing surface; the roller bracket 300 has a positioning part corresponding to the adjusting wheel 400, and the roller bracket 300 can limit the relative position of the adjusting wheel 400 and the roller bracket 300 through the positioning part.

[0031] The lighting adjustment device provided in this embodiment is very easy to operate when the user needs to adjust the brightness or mode of the lighting equipment. Simply turn the adjustment wheel 400 mounted on the roller bracket 300 to rotate it relative to the roller bracket 300. During the rotation of the adjustment wheel 400, the adjustment section 410 mounted on it moves accordingly. When the adjustment section 410 moves to different positions, it applies different levels of pressure to the sensing surface of the pressure sensor 200 inside the main body 100 of the lighting equipment. The pressure sensor 200 can detect changes in pressure. Once the pressure sensor 200 receives different levels of pressure, it quickly and accurately converts this pressure information into different pressure signals and promptly sends them to the lighting control unit inside the lighting equipment. After receiving these different pressure signals, the lighting control unit quickly switches between different lighting brightness or modes of the lighting equipment according to a preset program and logic, thereby instantly creating a lighting environment that meets the user's needs.

[0032] After the adjustment is completed, the positioning part on the roller bracket 300 limits the position of the adjustment wheel 400. In this way, it is ensured that the adjustment wheel 400 is always in a stable state, thereby providing a continuous and stable pressure signal to the pressure sensor 200. In this way, the lighting equipment can always maintain stable operation at the lighting brightness or mode adjusted by the user, avoiding problems such as lighting flickering or unexpected mode switching caused by unstable pressure signals.

[0033] As can be seen from the complete adjustment process described above, this embodiment utilizes the rotation of the adjusting wheel 400 to provide different levels of pressure to the pressure sensor, thereby adjusting the lighting mode of the lighting equipment. Compared with the traditional press-type adjustment structure, this adjustment method has significant advantages. In the traditional press-type adjustment structure, users often find it difficult to accurately grasp the pressing force and depth, resulting in unclear adjustment levels and easy errors during operation. However, the adjustment method of this invention allows users to more intuitively feel the changes in the travel of the adjusting wheel 400 during rotation, thus gaining a clearer and more accurate understanding of each adjustment level. This makes operation more convenient and allows users to easily achieve precise adjustments, greatly improving the convenience and accuracy of operation and effectively ensuring the user's experience with the lighting equipment.

[0034] Furthermore, the limiting part of the adjusting wheel 400 further improves the stability and reliability of the continuous pressing pressure provided by the adjusting wheel 400 to the pressure sensor 200. Regardless of how the user moves the lighting equipment or whether it is subject to minor external disturbances, the adjusting wheel 400 remains stable, continuously providing a stable pressure signal to the pressure sensor 200. This ensures that after the user adjusts the light, the lighting equipment can consistently output the required light, providing reliable lighting protection for the user.

[0035] In some specific embodiments, the side of the adjusting wheel 400 near the pressure sensor 200 is a curved convex surface, which forms the adjusting section 410. From the perspective of working principle, when a user needs to adjust the lighting of the lighting equipment, they will rotate the adjusting wheel 400. During the rotation of the adjusting wheel 400, the adjusting section 410 formed by its curved convex surface will move accordingly and make pressing contact with the sensing element of the pressure sensor 200. Setting the adjusting section 410 as a curved convex surface has significant advantages. Because the curved convex surface has continuous and smooth curved surface characteristics, this allows the adjusting section 410 to make pressing contact with the sensing element of the pressure sensor 200 extremely smoothly and continuously as the adjusting wheel 400 rotates.

[0036] Specifically, in some traditional adjustment structures, the contact between the adjustment component and the sensing component may be intermittent or exhibit significant step-like changes. This leads to unstable pressure signal output during adjustment, thus affecting the smoothness of lighting adjustment. However, the arc-shaped convex surface design in this embodiment allows the adjustment section 410 to apply pressure to the sensing component in a gradual and continuous manner when in contact with it. As the adjustment wheel 400 continues to rotate, the pressure applied by the adjustment section 410 to the sensing component changes uniformly, thereby achieving continuous and uninterrupted pressure on the pressure sensor 200.

[0037] Upon receiving this continuous pressure change signal, the pressure sensor 200 converts it into a corresponding electrical signal and transmits it to the control module of the lighting equipment. Based on the received electrical signals, the control module precisely controls relevant parameters of the lighting, such as brightness and color temperature, achieving stepless adjustment of the lighting. Stepless adjustment means that users can freely select the desired lighting state within the adjustment range of the lighting equipment according to their actual needs, without being limited by fixed settings. This flexible and precise adjustment method can maximize the satisfaction of users' lighting needs in different scenarios, greatly ensuring a better user experience and making the use of lighting equipment more convenient, comfortable, and personalized.

[0038] In some specific embodiments, the starting end and ending end of the adjustment segment 410 are the nearest end 411 and the farthest end 412, respectively; the distance between the axis of the rotation shaft 420 and the side of the adjustment wheel 400 where the adjustment segment 410 is located gradually increases from the nearest end 411 to the farthest end 412; when the user rotates the adjustment wheel 400, the interaction between the adjustment segment 410 of the adjustment wheel 400 and the pressure sensor 200 will change accordingly depending on the direction of rotation. Specifically, if the user rotates the adjustment wheel 400 in a certain direction, as the adjustment wheel 400 rotates, the adjustment segment 410 will gradually move closer to the sensing surface of the pressure sensor 200 from the nearest end 411 or the farthest end 412 and press against it, so that the pressing force applied by the adjustment segment 410 to the pressure sensor 200 when it moves relative to the pressure sensor 200 will also steadily decrease or increase.

[0039] This design offers users significant convenience. Firstly, users can easily understand the intuitive relationship between the rotation direction of the adjustment wheel 400 and changes in top pressure. No complex instructions or professional training are required; simply rotating the adjustment wheel 400 allows users to feel the steady increase or decrease in pressure on the lighting equipment as the rotation direction changes, thus understanding how this operation affects the light. Secondly, this stable and predictable pressure change enables users to efficiently adjust the lighting equipment. Users can quickly and accurately adjust parameters such as brightness and mode by rotating the adjustment wheel 400 according to their actual needs, without repeated trials and adjustments, greatly saving operating time and effort and improving the user experience.

[0040] In some specific embodiments, the roller bracket 300 has a positioning groove 310 on its side near the adjusting wheel 400. The positioning groove 310 forms a positioning part. Multiple positioning protrusions 413 corresponding to the positioning groove 310 are evenly distributed along the circumferential direction of the rotation axis 420 on the adjusting section 410. The positioning protrusions 413 can pass into the positioning groove 310 and have a certain elastic deformation capability. When the user needs to adjust the lighting equipment, the adjusting wheel 400 is driven to rotate relative to the roller bracket 300. During rotation, each positioning protrusion 413 deforms when it contacts the positioning groove 310. Specifically, when a positioning protrusion 413 rotates to a position close to the positioning groove 310, due to the combined action of the compression exerted by the positioning groove 310 and the rotational force, the positioning protrusion 413 gradually bends and compresses, undergoing elastic deformation, and finally extends and passes into the positioning groove 310. As the adjusting wheel 400 continues to rotate, the positioning protrusion 413, which has already entered the positioning groove 310, will be squeezed by the edge of the positioning groove 310, deform again, and come out of the positioning groove 310. As the adjusting wheel 400 continues to rotate, each positioning protrusion 413 will repeat this process of entering and exiting the positioning groove 310 in turn.

[0041] The interaction between the positioning protrusion 413 and the positioning groove 310 provides the user with a clear sense of the gear position when rotating the adjustment wheel 400. Just like when operating a mechanical device with clearly defined gears, each rotation to a specific position provides clear feedback, letting the user know that a gear has been reached. In this embodiment, by feeling the change in resistance and the "click" sound as the positioning protrusion 413 enters and exits the positioning groove 310, the user can clearly perceive the current gear position of the adjustment wheel 400, thus ensuring accurate adjustment of the lighting equipment and avoiding over- or under-adjustment.

[0042] After the user completes the adjustment, the positioning protrusion 413, which is close to the positioning groove 310, will naturally fall into the positioning groove 310 under its own elasticity. The positioning groove 310 can confine the positioning protrusion 413 within it, thereby effectively limiting the relative position of the adjusting wheel 400 and the roller bracket 300. This limitation can prevent the adjusting wheel 400 from rotating accidentally without human operation, ensuring that the lighting equipment always remains in the state adjusted by the user, providing the user with a stable and reliable lighting effect.

[0043] In some specific embodiments, the side of the adjusting wheel 400 opposite to the adjusting section 410 is a toggle section 430, and at least part of the toggle section 430 protrudes from the side of the main body 100 to facilitate the user's toggle operation of the adjusting wheel 400.

[0044] In some specific embodiments, a limiting surface 440 is provided at the intersection of the farthest end 412 of the actuating section 430 and the adjusting section 410. The limiting surface 440 is disposed away from the pressure sensor 200. Rotating the adjusting wheel 400 drives the nearest end 411 of the adjusting wheel 400 to approach the sensing surface of the pressure sensor 200, so that the limiting surface 440 abuts against the roller bracket 300, thereby limiting the rotation stroke of the adjusting wheel 400 and preventing the adjusting section 410 and the pressure sensor 200 from disengaging during the rotation of the adjusting wheel 400, thus ensuring the reliability of this embodiment.

[0045] In some specific embodiments, the actuating section 430 is an arc-shaped surface protruding away from the pressure sensor 200, in order to ensure the user's comfort when actuating the adjustment wheel 400, and to ensure the user's experience in this embodiment.

[0046] In some specific embodiments, the side surface of the adjustment wheel 400 where the toggle segment 430 is located has anti-slip texture to increase the friction when the toggle segment 430 comes into contact with the user's hand, reduce the probability of slippage, and ensure the user's experience.

[0047] like Figure 3 As shown, in some specific embodiments, the main body 100 is provided with a protective shell 110 corresponding to the adjusting wheel 400. The protective shell 110 covers the outside of the adjusting wheel 400, and the protective shell 110 has a toggle opening 111 corresponding to the shape of the toggle section 430, so as to protect the adjusting wheel 400, reduce the probability of the adjusting wheel 400 being damaged due to external influences, and further ensure the reliability of this embodiment.

[0048] The present invention also provides a lighting device, which may be a small flashlight, searchlight, or the like. The lighting device includes a main body 100 and a light adjustment device as described in the above embodiment. The light adjustment device is mounted on the main body 100. The lighting device has all the beneficial effects of the light adjustment device, which will not be described in detail here.
