[0029] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0030] Reference will be made below to Figures 1 - 6 describe the lamp controller 100 according to an embodiment of the present utility model, and the present utility model also proposes a study desk.

[0031] Referring to Figures 1 - 6 as shown, the lamp controller 100 according to an embodiment of the present utility model includes: a housing 10, a circuit board 12, a wire harness, and a wire pressing plate 14.

[0032] The housing 10 is provided with a wire hole 11. The circuit board 12 is disposed inside the housing 10. A button 13 electrically connected thereto is provided on the circuit board 12. The wire harness passes through the wire hole 11 and is electrically connected to the circuit board 12. The housing 10 is used to protect the circuit board 12, the wire harness, and other electrical components inside the lamp controller 100, prevent physical damage, dust, moisture, etc. from the outside from invading the circuit, and can also prevent the electrical components from being exposed, avoid safety accidents when the user operates, extend the service life of the lamp controller 100, and ensure its stable operation.

[0033] The internal space of the housing 10 of the lamp controller 100 is relatively large, and there is space left between each component and the housing 10, which can help the internal components dissipate heat better, maintain the normal operating temperature of the lamp controller 100, and avoid damage or failure caused by overheating. The housing 10 can also provide structural support for each internal component of the lamp controller 100, keeping it stable and in a fixed position, thus ensuring the normal function of the controller.

[0034] The circuit board 12 is used to control and manage the lamps. Circuits are integrated on the circuit board 12, and different circuits with different functions respectively correspond to different buttons 13. When receiving a user's instruction, that is, when the user presses a certain button 13, the circuits on the circuit board 12 transmit signals to the lamps through a wire harness to implement the user's instruction. For example, when the user presses the switch button, the circuit board controls the supply or cut-off of the power supply of the lamp to control the power-on or power-off of the lamp. Another example is that when the user presses the light adjustment button, the circuit board 12 adjusts the input voltage or current through the dimming circuit to control the change of the lamp brightness, so as to create a more comfortable lighting environment.

[0035] In addition, the circuit board 12 can perform timing tasks or scene settings through preset programming, such as turning the lamp on and off at a fixed time or automatically adjusting the lamp brightness under certain conditions, improving the convenience of use. That is to say, the buttons 13 on the lamp controller 100 can be set as a switch button, a brightness adjustment button, a mode adjustment button, etc.

[0036] The wire pressing plate 14 is installed in the housing 10 and forms a wire pressing space with the housing 10. The wire harness passes through the wire pressing space. That is, a wire hole 11 is provided on the housing 10, and the wire pressing plate 14 is arranged on one side of the wire hole 11. The wire harness extends into the housing 10 from the wire hole 11, and the wire pressing plate 14 restricts the wire harness in the wire pressing space, which can fix the position of the wire harness, prevent the wire harness from moving or loosening during use, ensure the stability of the electrical connection, and reduce the risk of failure.

[0037] When the product is subjected to a pressure test, since the wire hole 11 is installed in the housing 10 and the wire harness is restricted in the wire pressing space of the wire pressing plate 14, the wire pressing plate 14 can apply a certain pressure to the wire harness to prevent the wire harness from being pulled out of the housing 10, improving the yield of the product. However, since a wire pressing space is formed between the wire pressing plate 14 and the housing 10 and the height of the wire pressing space is sufficient for the wire harness to pass through, although the wire pressing plate 14 applies a certain pressure to the wire harness, it will not completely press the wire pressing plate 14 onto the wire harness, which does not affect the normal use of the wire harness and will not damage the surface of the wire harness.

[0038] Therefore, by providing the wire pressing plate 14 beside the wire hole 11 of the housing 10, the wire pressing plate 14 restricts the wire harness in the wire pressing space and applies a certain pressure, preventing the wire harness from being pulled out of the housing 10 during the pressure test and improving the yield of the product.

[0039] Refer toFigures 2 - 3 As shown, the wire pressing plate 14 is provided with a pressing strip 141 extending towards the bottom wall of the housing 10. The pressing strip 141 is arranged below the wire pressing plate 14. A wire hole 11 is provided on the bottom wall of the housing 10. The wire harness extends into the housing 10 through the wire hole 11. The extension of the pressing strip 141 towards the bottom wall of the housing 10 can press the wire harness against the bottom wall of the housing 10, preventing the wire harness from being pulled out of the housing 10. It can also fix the position of the wire harness, prevent the wire harness from moving or loosening during use, ensure the stability of electrical connection, and reduce the risk of failure.

[0040] Referring to Figures 4 - 5 As shown, there are at least two pressing strips 141, and the at least two pressing strips 141 are arranged at intervals on the wire pressing plate 14. In this embodiment, two pressing strips 141 are provided below the housing 10, and the two pressing strips 141 are arranged at intervals on both sides in the width direction of the wire pressing plate 14, that is, there is one pressing strip 141 on each side for fixing the wire harness. By providing at least two pressing strips 141, the fixing effect of the wire harness can be enhanced. The at least two pressing strips 141 make the pressure received by the wire harness more evenly distributed, preventing the wire harness from shifting or loosening during use. Moreover, the at least two pressing strips 141 can provide a larger contact surface, reduce the pressure received by a single position of the wire harness, and extend the service life of the wire harness.

[0041] The pressing strip 141 can also be three, four or more. In addition, multiple pressing strips 141 arranged at intervals can also be provided on the same side in the length direction of the wire pressing plate 14. The gap between two adjacent pressing strips 141 can allow a wire harness with a larger size to pass through, and can also fix the wire harness, which can improve the generalization degree of the wire pressing plate 14 and has a wider application range.

[0042] Referring to Figures 2 - 4 As shown, first connection holes 142 are provided at both ends of the wire pressing plate 14, and two second connection holes 15 are provided on the housing 10. The fastener passes through the first connection hole 142 and is fixedly connected to the second connection hole 15. That is to say, the wire pressing plate 14 and the housing 10 can be connected by fasteners. The wire pressing plate 14 and the housing 10 fixed by fasteners can withstand greater forces and tensile forces, ensuring that the wire pressing plate 14 is not easily loosened during long-term use. Metal fasteners are usually corrosion-resistant and wear-resistant, and the connection has good durability and a long service life. When maintenance or component replacement is required, using fasteners for connection is easier to disassemble and reinstall.

[0043] Among them, the first connection holes 142 at both ends of the wire pressing plate 14 and the second connection holes 15 on the housing 10 can be threaded holes, and the fastener can be a bolt.

[0044] Both ends of the wire pressing plate 14 are provided with first clamping portions, and two second clamping portions are provided on the housing 10. The first clamping portions are in clamping fit with the second clamping portions. In other embodiments, the wire pressing plate 14 can also be clamped with the housing 10. The clamping design makes the installation and disassembly process of the wire pressing plate 14 and the housing 10 more convenient, without the need for additional tools, saving time and labor costs.

[0045] Among them, the first clamping portion can be a bayonet or a buckle, the second clamping portion can be a buckle or a bayonet, and the buckle can be designed as a self-locking or detachable structure, improving flexibility and adapting to diverse product requirements. Moreover, the manufacturing and material costs of the buckle are usually low, suitable for mass production, and reducing product costs.

[0046] Refer to Figure 3 and Figure 6 As shown, a plurality of support ribs 16 are arranged at intervals on the circumferential side of the inner wall of the housing 10. The circuit board 12 abuts against the support ribs 16, and a wire passing space is formed between the circuit board 12 and the bottom wall of the housing 10. The plurality of support ribs 16 are evenly distributed on the inner wall of the housing 10, forming multi-point support for the circuit board 12, preventing the circuit board 12 from being displaced, distorted or loosened during use, ensuring that the circuit board 12 is always in an ideal working state. The support ribs 16 on the inner wall of the housing 10 can absorb the stress caused by external impact or vibration, reducing the risk of damage to the circuit board 12 and its components.

[0047] Moreover, the design of the support ribs 16 leaves a certain gap between the circuit board 12 and the housing 10, which helps to dissipate heat, prevent the circuit board 12 from overheating, and improve the reliability and service life of the device.

[0048] During the assembly process, the circuit board 12 is fixed by the support ribs 16, simplifying the assembly process of the lamp controller 100 and reducing the time for positioning the circuit board 12. During maintenance and repair, the disassembly and replacement of the circuit board 12 become more convenient.

[0049] In addition, the lamp controller 100 further includes: a diffusion plate, which is clamped between the button 13 and the circuit board 12, and the diffusion plate is used to evenly diffuse light. The button 13 of the lamp controller 100 is a light-emitting button 13. On the one hand, it improves the aesthetic degree of the lamp controller 100. On the other hand, the light-emitting button 13 is easy to identify in a low-light environment, and users can quickly find and operate the switch. Moreover, the working state of the lamp controller 100 and the lamp can be displayed by the color, brightness and flashing frequency of the light emitted by the button 13. Users can quickly understand through the light-emitting state of the button 13, and the visual feedback is intuitive, improving the use experience. The diffusion plate clamped between the button 13 and the circuit board 12 does not affect the use of the button 13 and the signal transmission of the circuit board 12. The diffusion plate diffuses the light of the button 13, increasing the distribution range of the light of the button 13 and improving the visibility and aesthetic degree of the button 13.

[0050] The diffuser plate can be one of a silicone pad, a PC light guide plate, and frosted glass. Among them, silicone has a certain degree of transparency and can conduct and diffuse the light emitted by the conductive button 13. However, the silicone material is not completely transparent, and the emitted light is softer. The silicone pad also has good softness and elasticity, can be molded according to the shape of the button 13, can improve the touch feeling of the button 13, can also shock-absorb and reduce the noise during the operation of the button 13, making the user feel more comfortable during operation.

[0051] The PC light guide plate, also known as the polycarbonate light guide plate, has good light transmittance and light guiding performance, can evenly distribute light. The PC light guide plate has high strength and good impact resistance, can be designed into various shapes and thicknesses, and has a relatively light mass, which is convenient for installation and use.

[0052] The frosted glass increases the surface roughness through surface treatment, can scatter light, and at the same time has high temperature resistance and chemical corrosion resistance, is suitable for various environments, and has good aesthetics.

[0053] The housing 10 can be a plastic housing 10. The plastic housing 10 has good electrical insulation performance, can effectively prevent current leakage, protect users from electric shock, and ensure the safety of the lamp controller 100. The housing 10 made of plastic material is lighter, can reduce the overall weight of the lamp controller 100, is convenient for installation, and can be fixed on the wall or other fixed devices. In addition, the cost of the plastic housing 10 is relatively low, can reduce the production cost of the lamp controller 100, and make the product more competitive.

[0054] The study desk according to the second aspect embodiment of the present utility model includes: a lamp controller 100.

[0055] Refer to Figure 1 As shown, a fixing plate 17 is provided below the housing 10 in the lamp controller 100. Two third connection holes 171 are provided on the fixing plate 17. The housing 10 can be fixed on the study desk by passing fasteners through the third connection holes 171. Users can easily reach and operate it without having to search everywhere or move the lamp controller 100, avoiding the loss of the lamp controller 100. It is especially suitable for the needs of frequently adjusting the light brightness or switch during daily study or work, and the operation is more convenient. Fixing the lamp controller 100 can also prevent the wire harness and the lamp controller 100 from being randomly stacked on the study desk. Fixing the lamp controller 100 on the edge of the study desk can also reduce the desktop space occupied by the lamp controller 100, keeping the desktop clean, orderly and beautiful. Moreover, after fixing the lamp controller 100, potential safety hazards such as wire harness pulling and socket detachment caused by movement or collision can be avoided.
