[0002] In everyday office and home lighting scenarios, desk lamps are commonly used lighting fixtures, and the ease of operation and long-term reliability of their switches directly affect the user experience. Currently, plug-in desk lamps on the market often use direct press switches to control the on / off of the lamp beads. Traditional press switches often have a short stroke design, making it difficult to meet the demand for an extended switch in the overall shape of the lamp fixture.

[0003] Furthermore, in practical applications of extending pushbutton switches, the prior art still faces many challenges. Most of the prior art switch modules are standardized in size, and it is not possible to flexibly adjust the length and shape of the extension segment according to the actual structure and design needs of the lamp housing. Therefore, it is usually necessary to use additional adapter parts to complete the assembly. This increases the complexity and cost of production and assembly, and destroys the appearance integrity and structural harmony of the lamp.

DETAILED DESCRIPTION OF THE INVENTION

[0021] This application provides a lighting device switch structure and a desk lamp, and in order to make the purpose, technical solution and effects of the invention clearer and more explicit, the invention will be described in more detail below. It should be understood that the specific embodiments described herein are only for illustrating the invention and are not intended to limit the invention.

[0022] Furthermore, unless otherwise specified in the specification, the terms "a," "the ...

[0023] In the prior art, most of the conventional switch modules are standardized in size, and the length and shape of the extension segment cannot be flexibly adjusted according to the actual structure and shape needs of the lamp housing, and they usually require additional adapter parts for assembly, which increases the complexity and cost of production and assembly and destroys the appearance unity and structural harmony of the lamp housing.

[0024] To solve the above problems, this application discloses a lighting device switch structure. With this lighting device switch structure, a user can trigger the switch by simply pressing the downwardly extending switch inner tube, achieving a smooth, linear pressing operation. After releasing the switch, the switch automatically and quickly returns to its initial position under the action of the elastic reset member, ready for the next operation. This design improves usability and avoids the high costs and potential failure risks associated with the frequent installation of complex adapter parts.

[0025] Specifically, as shown in FIG. 1, the lighting device switch structure includes an outer tube 101, an inner tube 102, an elastic reset member, a circuit trigger assembly 104 and a lighting assembly 300.

[0026] The circuit trigger assembly 104 is electrically connected to the lighting fixture to form a circuit for controlling switching of the lighting state of the lighting fixture. The lighting assembly 300 is disposed opposite the circuit trigger assembly 104. The outer tube 101 is fixed to the circuit trigger assembly 104. The inner tube 102 is drilled to be slidably fitted within the outer tube 101 and is slidably mounted on the outer tube 101 along the axial direction of the outer tube 101. The lower end of the inner tube 102 abuts against the circuit trigger assembly 104 and triggers the circuit trigger assembly 104 by pressing the inner tube 102. The elastic reset member is disposed between the inner tube 102 and the circuit trigger assembly 104 to reset the inner tube 102 after pressing the inner tube 102 to press the circuit trigger assembly 104.

[0027] Furthermore, the inner tube 102 is drilled so as to be slidably fitted into the outer tube 101, and is slidable relative to the outer tube 101 along the axial direction of the outer tube 101. The lower end of the inner tube 102 is provided corresponding to the circuit trigger assembly 104, and the lighting state can be turned on and off by pressing the inner tube 102 to trigger the circuit trigger assembly 104.

[0028] Furthermore, as shown in FIG. 2 , the inner tube 102 is drilled and slidably fitted into the outer tube 101. This external fitting method stabilizes the mechanical structure of the inner tube 102 and the outer tube 101 and prevents external dust and water vapor from entering the switch, thereby extending the service life of the switch. The inner tube 102 may have a hollow structure or a solid structure, without any limitation. The axis of the inner tube 102 overlaps with the axis of the outer tube 101, thereby ensuring smooth and stable sliding of the inner tube 102 along the outer tube 101 and avoiding uneven load friction and jerkiness. The user can control the on / off state of the light by pressing the inner tube 102.

[0029] Specifically, as shown in FIG. 1, the elastic reset member has one end fixed to the inner tube 102 and the other end abutting against the circuit trigger assembly 104 to provide a rebound elastic force after the inner tube 102 is pressed.

[0030] Furthermore, one end of the elastic reset member is firmly connected to the inner tube 102. When the inner tube 102 is pressed down, the elastic reset member can store force and release the elastic potential as soon as the external force is removed, providing a stable and uniform repulsive force to the inner tube 102, ensuring that it is quickly reset to its initial position. The spring reset method not only has a quick response, but can also adapt to the rhythm of switch operation, and has good durability, can withstand high-frequency pressing and is not easily broken, ensuring the stability and reliability of the switch structure over a long period of use.

[0031] Furthermore, a cushion pad 106 may be additionally provided between the elastic reset member and the inner tube 102. The material of the cushion pad 106 is not limited thereto and may be the same as or different from the material of the inner tube 102. The cushion pad 106 may be provided separately from the inner tube 102 or may be integrally formed with the inner tube 102. The cushion pad 106 can absorb vibrations and impacts generated during the compression and rebound process of the spring 103, reduce mechanical wear of the elastic reset member itself and its surrounding structure, and suppress metallic noise that may be generated during operation, thereby improving the overall operability and durability of the switch.

[0032] Specifically, as shown in FIG. 1, the elastic reset member is a spring 103 having one end fixedly connected to the inner tube 102 and the other end abutting against the circuit trigger assembly 104 .

[0033] Furthermore, when the inner tube 102 is externally pressed and moves downward, the spring 103 is pressed and stores energy, and pushes the circuit trigger assembly 104 to realize circuit conduction, thereby switching the lighting state of the lamp. When the pressing force is released, the spring 103 releases elastic potential energy and drives the inner tube 102 to reset to its initial position along the axial direction, thereby realizing repeated triggering and stable resetting of the switch structure.

[0034] Specifically, as shown in FIG. 1, one end of the outer tube 101 is fixed to the circuit trigger assembly 104, and the outer tube 101 is fitted onto the inner tube 102 along the same axis, which is used to provide a guide for the sliding of the inner tube 102, limit the radial oscillation of the inner tube 102, and ensure the stability of the pressing and rebounding action of the inner tube 102.

[0035] Furthermore, the outer tube 101 is connected to the circuit trigger assembly 104 and may be tightly fitted to the lighting device body in a post-assembly fixing manner, or may be fixed to the lighting device body in a one-piece molding manner; this is not a limitation, and specific embodiments can be flexibly selected according to the actual product structure and production costs.

[0036] Furthermore, the outer tube 101 is fitted onto the inner tube 102 to form a sliding guide means. The outer tube 101 provides a guide path for the axial sliding of the inner tube 102, ensuring that the inner tube 102 always performs smooth pressing and rebounding movements along a predetermined trajectory, while also limiting the radial oscillation of the inner tube 102 during movement, thereby avoiding offset-induced jerking or trigger failure. The installation of this structure improves operational stability and maintains consistent force feedback and stroke for each press. Furthermore, the outer tube 101 provides physical protection for the inner tube 102, further improving the loss-resistance of the switch structure during long-term use.

[0037] Furthermore, the circuit trigger assembly 104 is disposed between the inner tube 102 and the spring 103, is located on the pressing stroke path of the inner tube 102, and forms an engaging relationship with the inner tube 102. When a user presses the inner tube 102, the inner tube 102 moves downward along its axial direction and contacts a trigger position, and the downward pressure of the inner tube 102 directly acts on the circuit trigger assembly 104, which realizes circuit closure and instantly completes the circuit conduction operation, thereby activating the lighting function.

[0038] Furthermore, the specific type of the circuit trigger assembly 104 is not limited, and the circuit trigger assembly 104 may be a micro switch provided on the depression stroke path of the inner tube 102. When the inner tube 102 is depressed, the inner tube 102 moves downward and presses the contact of the micro switch at the end of the stroke, quickly switching the internal contact of the micro switch from a "normally open" state to a "closed" state, thereby instantly turning on the lighting circuit and realizing the lighting function. The metal contact structure and high-speed on / off mechanism of the micro switch ensure high electrical reliability and a lifespan of hundreds of thousands of operations.

[0039] Furthermore, the circuit trigger assembly 104 may be a metal elastic piece disposed along the pressing stroke path of the inner tube 102, with an insulated conductive contact fixed to the bottom of the inner tube 102. When the inner tube 102 is pressed, the conductive contact follows the inner tube 102 downward until it simultaneously contacts two separated metal elastic pieces fixed below, thereby forming an electrical connection between them and bridging the circuit to achieve conduction. After release, the inner tube 102 rises under the action of the spring 103, and the conductive contact separates from the metal elastic pieces, automatically disconnecting the circuit.

[0040] Specifically, as shown in FIG. 2, the inner tube 102 has the same shape as the outer tube 101 , and the outer diameter of the inner tube 102 is smaller than the inner diameter of the outer tube 101 .

[0041] Furthermore, the cross section of the inner tube 102 and the cross section of the outer tube 101 adopt a similar shape, and the outer diameter of the inner tube 102 is slightly smaller than the inner diameter of the outer tube 101, thereby ensuring sufficient sliding space for the inner tube 102 and avoiding jamming or wear caused by over-tightening. Furthermore, by controlling the gap, radial vibration is minimized and stability of the pressing and rebounding process is ensured.

[0042] Specifically, as shown in FIG. 2, the axial mounting height of the inner tube 102 is higher than the axial mounting height of the outer tube 101, and the height difference between the inner tube 102 and the outer tube 101 is not smaller than the maximum pressing stroke of the inner tube 102, thereby ensuring that the inner tube 102 is higher than the end of the outer tube 101 during the pressing process and achieving a smooth pressing operation without any jerks.

[0043] Furthermore, the axial extension height of the outer tube 101 is greater than the axial extension height of the inner tube 102, and the height difference between the two is not smaller than the maximum pressing stroke of the inner tube 102. The height difference design leaves sufficient space for the pressing motion of the inner tube 102, thereby avoiding collision or pressing interference between the end of the inner tube 102 and the end of the outer tube 101 during the pressing process. It also ensures that the inner tube 102 is always within the guiding range of the outer tube 101 throughout the entire pressing stroke, eliminating jerks caused by height mismatch and ensuring circuit triggering. Ultimately, this achieves smooth and uninterrupted pressing operation, further improving the stability and smoothness of the switch.

[0044] Specifically, as shown in FIG. 2, at least one positioning notch 107 is provided on the circumferential side wall of the circuit trigger assembly 104 to limit the mounting position of the circuit trigger assembly 104 in the circumferential direction.

[0045] Furthermore, at least one positioning notch 107 is provided on a circumferential side wall of the circuit trigger assembly 104. The positioning notch 107 forms an insertion fit with a corresponding protrusion or pin shaft structure of the lamp body during assembly, thereby limiting the installation angle and position of the circuit trigger assembly 104 in the circumferential direction, thereby avoiding misalignment and incorrect installation during assembly, improving production efficiency and assembly consistency, ensuring that the electrical contacts of the circuit trigger assembly 104 are optimally aligned, improving trigger sensitivity, extending the service life of the element, and enhancing the stability and reliability of the entire light switch during long-term use.

[0046] 2 and 3, the circuit trigger assembly 104 is provided with a position limiting member 108, which is an opening penetrating in the axial direction. The lighting assembly 300 is fitted onto the position limiting member 108, and positioning is achieved by the position limiting member 108. The diameter of the position limiting member 108 is larger than the diameter of the outer tube 101, and the outer tube 101 passes through the position limiting member 108 in the axial direction, further achieving a fixed position of the outer tube 101.

[0047] Furthermore, the lighting assembly 300 is fitted onto the outer periphery of the position limiting member 108, and achieves radial and circumferential positioning through a tight fit with the position limiting member 108, thereby effectively preventing offset or rattle of the lighting assembly during operation. The aperture diameter of the position limiting member 108 is slightly larger than the outer diameter of the outer tube 101, thereby ensuring that the outer tube 101 can smoothly pass through the position limiting member 108 along the axial direction and will not rub against the position limiting member 108 during axial movement.

[0048] 2, at least one support post 600 is provided between the circuit trigger assembly 104 and the lighting assembly 300. Both ends of the support post 600 are fixedly connected to the circuit trigger assembly 104 and the lighting assembly 300, respectively, and the support post 600 is used to support and maintain the relative positions between the circuit trigger assembly 104 and the lighting assembly 300.

[0049] Furthermore, the support column 600 not only provides stable mechanical support for the circuit trigger assembly 104 and the lighting assembly 300, but also maintains an appropriate distance between the circuit trigger assembly 104 and the lighting assembly 300, maintains the relative position and axial distance between them, and ensures constant center alignment and operating distance between the trigger means and the lighting element, thereby avoiding failure of the electrical connection of the circuit trigger assembly 104 or reduction in optical performance due to heat generation by the lighting assembly 300.

[0050] The present application further provides a desk lamp, as shown in Figure 4, which is provided with the above-described lighting device switch structure, which realizes an extension of a conventional short-stroke switch without an additional adapter part, thereby reducing the complexity and cost of the lighting fixture and improving the stability of the desk lamp.

[0051] The quick release structure and desk lamp of the present application will be described below with specific examples.

[0052] In this embodiment, as shown in FIG. 5 , the desk lamp includes the above-described lighting device switch structure, a base 200, a battery assembly 400, a lamp cover 500, and a main body 700. The lighting device switch structure includes the outer tube 101, the inner tube 102, the elastic reset member, the lighting assembly 300, and the circuit trigger assembly 104. The inner tube 102 is drilled to be slidably fitted within the outer tube 101 and is slidable relative to the outer tube 101 along the axial direction of the outer tube 101, and the lighting state is turned on and off by pressing the inner tube 102. In this application, the sliding structure provides a stable and constrained linear motion path, ensuring that the pressing motion always occurs in a predetermined direction, avoiding switch trigger failure, structural wear, and jerky operation caused by lateral swing or offset.

[0053] 5, the elastic reset member is a spring 103 having one end connected to the inner tube 102 and the other end connected to the circuit trigger assembly 104, for providing a rebound elastic force after the inner tube 102 is pressed. As an elastic reset member, the spring 103 is characterized by stable deformation and uniform rebound force. The fixed manner in which both ends are connected to the inner tube 102 and the circuit trigger assembly 104, respectively, ensures that the inner tube 102 accurately resets to its initial position after being pressed. When the inner tube 102 is pressed down, the spring 103 compresses and stores elastic potential energy, and when the pressure is released, the spring 103 releases the energy, pushing the inner tube 102 to stably return to its initial position. This ensures reliable resetting every time the switch is operated and avoids problems such as contact contact and mechanical jerking due to insufficient resetting.

[0054] 4 and 5, one end of the outer tube 101 is fixed to the circuit trigger assembly 104, and the outer tube 101 is fitted coaxially around the inner tube 102 to provide a guide for the sliding of the inner tube 102, limit its radial oscillation, and ensure the stability of the inner tube's pressing and rebounding motion. The circuit trigger assembly 104 is located at the end of the pressing stroke path of the inner tube 102. When the inner tube 102 is pressed to a designated position, a trigger portion at the lower end of the inner tube 102 contacts and drives the circuit trigger assembly 104, which then conducts the circuit to turn on or off the lighting circuit and realize the lighting or extinguishing function of the lighting device. The circuit trigger assembly 104 may be a micro-switch or a metal elastic piece, but is not limited thereto.

[0055] Furthermore, as shown in FIG. 4, the inner tube 102 and the outer tube 101 have a coaxial tubular structure, and the outer diameter of the inner tube 102 is slightly smaller than the inner diameter of the outer tube 101, thereby forming a sliding fit gap between the inner tube 102 and the outer tube 101, ensuring that the inner tube 102 can slide smoothly axially inside the outer tube 101.

[0056] 4, the mounting height of the inner tube 102 in the axial direction is higher than the mounting height of the outer tube 101 in the axial direction, and the height difference between the inner tube 102 and the outer tube 101 is not smaller than the maximum pressing stroke of the inner tube 102. The design of the mounting height difference ensures that when the inner tube 102 is fully pressed to the maximum stroke, the tip of the inner tube 102 can remain above the top of the outer tube 101 and no mechanical collision occurs with the outer tube 101, avoiding the problem of end interference during pressing and ensuring smooth and jerky pressing throughout the entire stroke, and further preventing deformation, wear, and damage to components due to excessive pressing or mechanical collision, thereby improving the reliability of switch operation and the service life of the entire structure.

[0057] Furthermore, at least one, for example, two or three positioning notches 107 are provided on the circumferential sidewall of the circuit trigger assembly 104, and the number can be limited according to actual circumstances. The positioning notches 107 are used to limit the mounting position of the circuit trigger assembly 104 in the circumferential direction.

[0058] Furthermore, the circuit trigger assembly 104 is provided with the position limiting member 108, which has an aperture structure penetrating in the axial direction. The lighting assembly 300 is fitted onto the outer periphery of the position limiting member 108, and the position limiting member 108 realizes its radial and circumferential positioning and prevents assembly offset or rattle. The aperture diameter of the position limiting member 108 is slightly larger than the outer diameter of the outer tube 101, allowing the outer tube 101 to smoothly pass through the aperture along the axial direction, and the structure of the position limiting member 108 realizes reliable fixation of the axial position of the outer tube 101.

[0059] 5, at least one support post 600 is provided between the circuit trigger assembly 104 and the lighting assembly 300, and both ends of the support post 600 are rigidly and fixedly connected to the circuit trigger assembly 104 and the lighting assembly 300, respectively. The support post 600 provides stable mechanical support to the circuit trigger assembly 104 and the lighting assembly 300 and is used to ensure a constant center alignment and operating distance between the trigger means and the lighting element. The support post 600 may be made of a metal material to form an auxiliary heat dissipation path, which conducts heat generated in the lighting assembly 300 to the circuit trigger assembly 104 or a heat dissipation area of ​​a larger area, thereby delaying light attenuation and extending the service life of the lamp.

[0060] Furthermore, as shown in FIG. 6 , the lamp cover 500 has a light-transmitting structure, and may be made of, but is not limited to, acrylic or glass materials with good light transmittance. A position limiting ring that fits the inner tube 102 may be provided on the inner wall of the top of the lamp cover 500. The inner diameter of the position limiting ring is sized to fit the outer diameter of the tip of the inner tube 102. When the lamp cover 500 is installed, the position limiting ring and the tip of the inner tube 102 form an abutting relationship. The abutting relationship provides a restraining effect that allows the lamp cover 500 to be stably attached to the inner tube 102, preventing rattle, offset, or detachment due to daily use or slight external forces. Pressing the top of the lamp cover 500 and then pushing the inner tube 102 downward along the axial direction triggers the circuit trigger assembly 104, thereby changing the on / off state of the circuit and ultimately turning the lighting assembly 300 on and off. In addition, the engagement of the position limiting ring with the inner tube 102 also serves to position the lamp cover 500, ensuring that the optical assembly is always maintained in its designed position, enhancing the structural integrity and stability, and ensuring the uniformity and aesthetics of the light irradiation effect.

[0061] Furthermore, as shown in FIG. 6 , the desk lamp further includes a charging base 800, which is detachably connected to the base 200 via an interface, and the base 200 is provided with the battery assembly 400. The charging circuit is electrically connected to the battery assembly 400 on the base 200. When an external power source is connected, the battery assembly 400 is charged, and when the external power source is cut off, the battery assembly 400 is used to power the lighting assembly 300, thereby realizing the uninterruptible lighting function of the desk lamp.

[0062] Therefore, the present application provides a desk lamp, in which the outer tube is fixedly attached to the circuit trigger assembly, the inner tube is slidably fitted inside the outer tube and has its lower end abutting the circuit trigger assembly, the cushion pad is provided between the inner tube and the circuit trigger assembly, and the elastic reset member is provided between the inner tube and the circuit trigger assembly. The circuit trigger assembly and the lighting assembly are both mounted on the main body, and their relative positions are maintained via the support pillar. The circuit trigger assembly has a circumferential positioning notch and is aligned with the lighting assembly via the position limiting member. The lighting assembly is mounted on the base, and the battery assembly is located below the circuit trigger assembly and housed in the base, and the circuit trigger assembly is electrically connected to the lighting assembly, the battery assembly, and the inner tube, respectively. The lamp cover is fixedly attached to the upper end of the inner tube, and its top inner wall abuts against the tip of the inner tube.

[0063] During operation, a user presses the upper end of the inner tube, causing it to slide axially downward along the outer tube and compress the resilient reset member. The lower end of the inner tube presses the circuit trigger assembly, triggering the operation of its internal electrical contacts and turning the circuit on or off, thereby switching the lighting state of the lighting assembly. After releasing the pressure, the resilient reset member releases its elastic potential energy and pushes the inner tube back axially to its initial position, resetting the circuit trigger assembly accordingly and completing one on / off operation. The battery assembly introduces external power energy via the base's power line to power the entire system.

[0064] As described above, this application discloses a lighting device switch structure, comprising: a circuit trigger assembly electrically connected to the lighting fixture to form a circuit for controlling switching of the lighting state of the lighting fixture; a lighting assembly disposed opposite the circuit trigger assembly; an outer tube fixed to the circuit trigger assembly; an inner tube bored into the outer tube so as to be slidably fitted therein, slidably disposed on the outer tube along the axial direction of the outer tube, and having a lower end abutting the circuit trigger assembly, the inner tube triggering the circuit trigger assembly when pressed; and an elastic reset member disposed between the inner tube and the circuit trigger assembly, pressing the inner tube to reset the inner tube after the inner tube has pressed the circuit trigger assembly. According to the lighting device switch structure described in this application, the outer tube serves as a fixed base, providing a stable mounting foundation and support for the entire lighting device switch structure. The inner tube is slidably fitted within the outer tube, forming a sleeve-sliding pair structure with the outer tube, thereby realizing a smooth, directional linear pressing stroke, forming an extendable switch and providing a smooth operating feel to the user. The elastic reset member is located at one end of the inner tube, storing energy when pressed and rebounding when released, ensuring that the inner tube automatically and quickly returns to its initial position each time it is triggered, ensuring the long-term durability and operational consistency of the lighting device. The circuit trigger assembly is fixed to the bottom end of the inner tube and is triggered by pressing the inner tube, efficiently converting mechanical movement into an electrical signal and further controlling the circuit on and off. As described above, the lighting device switch structure described in this application can achieve an extension of a conventional short-stroke switch without using an additional adapter part, thereby reducing the complexity and cost of the lighting device and improving the stability of the lighting device.
