Technical Field

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

[0002] With the increasing sophistication of modern industrial production, medical examinations, and daily home life, lighting equipment, as an important tool for assisting vision, has received widespread attention for its functionality. In application scenarios such as precision instrument repair, surgical lighting, jewelry appraisal, or desk reading, users have extremely high requirements for the quality of light, not only needing appropriate light intensity, but also requiring dynamic adjustment of the projection angle and coverage of the light spot.

[0003] However, existing auxiliary lighting fixtures often have a relatively simple optical structure design. The distance between the internal light source and the front optical lens or reflector is usually fixed, which means that the fixture can only output a fixed lighting mode. It is either a floodlight mode with a large illumination range but low center brightness, or a spotlight mode with high center brightness but small coverage area. In actual use, the operator often needs to switch between them. Fixtures with fixed focal length cannot meet both needs at the same time, resulting in a poor user experience. It may even require multiple fixtures with different functions to cope with the situation, which wastes resources and makes the operation cumbersome.

[0004] Therefore, this utility model proposes a lamp with angle adjustment to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing auxiliary lighting fixtures, such as the fixed and non-adjustable optical focal length, which makes it impossible to simultaneously provide wide-area floodlight and local high-brightness spotlight, as well as the limited adjustment of the lighting angle and the difficulty in covering blind spots, this utility model aims to provide a lighting fixture with angle adjustment that has been structurally improved and can effectively solve the above problems.

[0006] This utility model adopts the following technical solution: a lamp with angle adjustment, comprising: a lamp support, and a flexible bent tube fixedly connected to the top of the lamp support, wherein a lampshade is fixedly connected to the end of the flexible bent tube away from the lamp support; the lamp also includes a connecting ring, which is fixedly connected to one end of the lampshade, and an extension tube is fixedly connected to the end of the connecting ring away from the lampshade, wherein a guide groove is formed on the outer wall of the extension tube; an adjusting tube is slidably sleeved on the outer wall of the extension tube, and a guide slider is fixedly connected to the inner wall of the adjusting tube, wherein the guide slider is slidably embedded in the guide groove, and a lens is fixedly connected to the guide slider through a connecting frame; the adjusting tube drives the lens to reciprocate along the length direction of the guide groove through the guide slider.

Then, the lens 3018 is precisely driven to reciprocate axially through the rigid connecting frame 3017.

[0028] Please see the appendix Figure 4 and attached Figure 5A connecting guide ring 2012 is fixedly provided on the outer wall of one end of the lampshade 2 and the connecting ring 3. A slot 2013 is provided on the inner wall of the connecting guide ring 2012. A positioning block 301 is fixedly provided on the inner wall of the connecting ring 3. The positioning block 301 is engaged and connected to the inside of the slot 2013. Mounting holes 101 are provided at the four corners inside the lamp holder 1. A wire groove 1011 is provided on one side of the lamp holder 1. The wire groove 1011 passes through the side wall of the lamp holder 1. Specifically, at the end of the lampshade 2 that connects to the connecting ring 3, a connecting guide ring 2012 is fixedly installed on its outer wall. The connecting guide ring 2012 has an annular groove 2013 evenly opened along its inner wall. At the corresponding position on the inner wall of the connecting ring 3, a number of positioning blocks 301 evenly distributed along the circumference are fixedly installed. The shape and size of the positioning blocks 301 are completely matched with the structure of the groove 2013, and can be embedded and fixed in the internal space of the groove 2013, thereby realizing a reliable connection and stable assembly between the lampshade 2 and the connecting ring 3, ensuring that the two do not undergo relative displacement during use. The main structure of the lamp holder 1 has symmetrically distributed mounting holes 101 at the four corners of the interior. On one side wall of the lamp holder 1, a wire groove 1011 is also specially opened, which not only ensures the convenience and safety of the electrical connection of the lamp, but also further enhances the functionality and practicality of the overall structure of the lamp.

[0029] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 6 A flexible shield 3013 is provided between the extension tube 3011 and the adjustment tube 3014. One end of the flexible shield 3013 is fixedly connected to the end of the guide groove 3012, and the other end of the flexible shield 3013 is fixedly connected to the outside of the guide slider 3016. The outer wall of the adjustment tube 3014 is provided with anti-slip grooves 3015 in a ring array. Specifically, a flexible shield 3013 is installed between the extension tube 3011 and the adjustment tube 3014. One end of the flexible shield 3013 is installed at the end of the guide groove 3012, and the other end is connected to the outer surface of the guide slider 3016. The flexible shield 3013 effectively prevents the intrusion of external dust, impurities and foreign objects, thereby ensuring the smooth operation of the internal moving components and avoiding jamming or wear caused by contamination. Multiple anti-slip grooves 3015 are opened on the circumferential direction of the outer wall of the adjustment tube 3014, which not only significantly increases the surface roughness and provides good friction characteristics, but also strengthens the overall mechanical strength and deformation resistance of the component, and improves the durability and reliability of the equipment in long-term use.

[0030] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3The outer wall of the lampshade 2 is fixedly provided with a heat sink 201, which is tightly attached to the outer wall of the lampshade 2. The outer wall of the lampshade 2 is also fixedly provided with an on / off switch 2011. The lamp bead 2014 is fixedly provided inside the lampshade 2, and the lamp bead 2014 is located on the side of the lens 3018 facing the lampshade 2. Specifically, several heat sinks 201 are fixedly installed on the outer wall surface of the lampshade 2. The heat sinks 201 are tightly fitted to the outer wall of the lampshade 2, ensuring that the heat generated when the lamp is working can be quickly and evenly conducted to the heat sinks 201. By increasing the heat dissipation area, the heat dissipation efficiency is significantly improved, thereby effectively reducing the working temperature of the lamp and significantly improving the overall heat dissipation performance. An on / off switch 2011 is also fixedly installed on the outer wall of the lampshade 2, allowing users to easily control the on and off state of the lamp, further improving the convenience of use. The LED beads 2014 are all located on the side of the lens 3018 facing the inside of the lampshade 2. This ensures that the emitted light can be fully focused by the lens 3018 and projected forward evenly and efficiently, effectively avoiding glare and light spots.

[0031] Working principle: When using the lamp, first place the lamp holder 1 stably on the designated position of the object to be installed on the table. Then, use the mounting holes 101 at the four corners of the lamp holder 1 to install the bolts. The lamp holder 1 is firmly connected to the object by tightening the bolts, ensuring the stability of the lamp after installation. At the same time, the wire harness can pass through the wire groove 1011 on one side of the lamp holder 1 in an orderly manner, providing a safe and stable power supply channel for the power components of the lamp 2014, making the wiring layout more organized and avoiding messy and tangled wire harnesses that may affect use or pose safety hazards. Since the flexible bending tube 1012 is fixedly installed at the top of the lamp support 1, and the lamp cover 2 is fixedly installed at the end of the flexible bending tube 1012 away from the lamp support 1, the flexible bending tube 1012 has the characteristic of being able to bend arbitrarily and maintain the bending angle. Therefore, by manually bending the flexible bending tube 1012, the lamp cover 2 can be adjusted in multiple directions and angles. At the same time, the heat sink 201 fixedly installed on the outer wall of the lamp cover 2 is in close contact with the outer wall of the lamp cover 2, which can quickly conduct and dissipate the heat generated by the lamp bead 2014 when it is working, and avoid the heat from accumulating inside the lamp cover 2 and causing the temperature to be too high, thereby effectively protecting the lamp bead 2014 component and extending the overall service life of the lamp. The on / off switch 2011 fixedly installed on the outer wall of the lamp cover 2 can be directly pressed manually to turn the lamp bead 2014 on and off, which is convenient and intuitive to operate. The connecting ring 3 is sleeved on the outer wall of the connecting guide ring 2012 at one end of the lamp cover 2. The positioning block 301 fixedly installed on the inner wall of the connecting ring 3 corresponds to and engages with the slot 2013 opened in the connecting guide ring 2012. Through the engagement of the positioning block 301 and the slot 2013, a stable connection between the connecting ring 3 and the lamp cover 2 is achieved, preventing the connecting ring 3 from falling off during use. The extension tube 3011 is fixedly installed at the end of the connecting ring 3 away from the lamp cover 2. The four guide grooves 3012 opened in a ring array on its outer wall are structurally regular, providing precise track support for the subsequent sliding of the guide slider 3016, ensuring the smoothness and stability of the sliding process. Because the adjusting tube 3014 is slidably sleeved on the outer wall of the extension tube 3011, and the four guide sliders 3016 fixed in a ring array on the inner wall of the adjusting tube 3014 correspond one-to-one with the four guide grooves 3012, and the guide sliders 3016 are slidably embedded in the guide grooves 3012, while one end of the flexible shield 3013 is fixedly connected to the end of the guide groove 3012 and the other end is fixedly connected to the outer side of the guide sliders 3016, when the adjusting tube 3014 is manually pushed, the adjusting tube 3014 will drive the guide sliders 3016 on the inner wall to slide linearly along the guide grooves 3012, and the sliding of the guide sliders 3016 will synchronously drive the connecting frame 3017 and the lens 3018 fixedly connected to the far end of the connecting frame 3017 to move, thereby flexibly adjusting the position of the guide sliders 3016. The distance between the adjustable lens 3018 and the lamp bead 2014 fixedly connected inside the lamp cover 2 is adjusted. When the lens 3018 is close to the lamp bead 2014, the illumination range will be reduced accordingly, and the light will be more concentrated, which is suitable for scenarios that require precise lighting. When the lens 3018 is away from the lamp bead 2014, the illumination range will be expanded accordingly, thereby meeting the usage needs of different lighting ranges. The anti-slip grooves 3015 formed by the annular array on the outer wall of the adjusting tube 3014 increase the contact friction between the hand and the outer wall of the adjusting tube 3014, preventing external dust and small impurities from entering the guide groove 3012, avoiding impurities from affecting the smooth sliding of the guide slider 3016, ensuring the long-term stable operation of the adjusting mechanism, and further improving the reliability and durability of the lamp.
