[0036] The present invention provides Figures 1 and 2 The LED spotlight reflector cup shown includes a first cup body 1 and a second cup body 2. The first cup body 1 and the second cup body 2 both have a light inlet and a light outlet. A limiting sleeve 4 is installed at the light outlet of the first cup body 1, and the light inlet of the second cup body 2 is threadedly connected to the limiting sleeve 4.

[0037] Specifically, a plurality of second cup bodies 2 of different models are provided. The reflective cup is assembled from the first cup body 1 and the second cup body 2. The second cup body 2 of different models can be replaced according to actual needs, which can flexibly adapt to scenes with different lighting effect requirements without redesigning or replacing the entire reflective cup, thereby improving the versatility and adaptability of the product.

[0038] For example, for small exhibits such as jewelry and jade, a smaller second cup body 2 is replaced. The smaller second cup body 2 usually has a smaller light outlet size. When the light outlet is smaller, the light can be reflected inside the reflective cup and emitted from the light outlet more concentratedly, thus forming a more focused light, just like the spotlight mode of a flashlight, which can illuminate the key parts of the exhibits.

[0039] Multiple models of the second cup body 2 provide users with a wider range of customization space, which can meet diverse lighting needs and special application scenarios.

[0040] The limiting sleeve 4 and the second cup body 2 are threadedly connected, which facilitates the replacement of the second cup body 2 and ensures the stability of the overall structure.

[0041] Reference Figure 1 、 Figure 2 As shown in FIG, a docking cup section 3 is provided at the light inlet of the first cup body 1 for docking with the lamp holder of the LED spotlight.

[0042] A reinforcement strip 201 is integrally formed on the outer wall of the second cup body 2. There are multiple reinforcement strips 201, and the multiple reinforcement strips 201 are evenly distributed around the second cup body 2. The reinforcement strips 201 are provided to reinforce the second cup body 2 and to increase friction, making it easier for the operator to hold the second cup body 2 and dock it with the limit sleeve 4.

[0043] The present invention provides Figures 3 to 8 An energy-saving LED spotlight shown uses the above-mentioned LED spotlight reflector cup and also includes a protection box 5. The protection box 5 is provided with a spotlight body 8 inside. The protection box 5 can be made of, but is not limited to, hard plastic material.

[0044] The bottom of the protection box 5 is fixedly connected to a mounting base 26 , which has a mounting hole. Bolts are passed through the mounting hole to fix the mounting base 26 on a wall or other location.

[0045] The spotlight body can be equipped with a light sensor at position 8, which automatically adjusts the brightness of the light source according to the intensity of the surrounding light. In strong ambient light, the light source brightness is reduced; in weak ambient light, the brightness is increased. This not only meets lighting needs, but also avoids energy waste caused by excessive lighting, achieving energy conservation goals.

[0046] Reference Figure 3 、 Figure 4 、 Figure 5 As shown in , considering that existing spotlight bodies 8 installed outdoors usually lack protective structures and are easily affected by the external environment, such as rain erosion and dust adhesion, which shortens the service life, the present invention provides protection for the spotlight body 8 by disposing a protective box 5 on the outside of the spotlight body 8. One end of the protective box 5 is provided with an opening, and a protective belt 13 is provided inside the protective box 5. The spotlight body 8 is located within the inner circle of the protective belt 13. The protective belt 13 can be made of, but is not limited to, rubber and can block rain. In actual use, the spotlight body 8 can be equipped with a cooling fan, etc., and the protective box 5 can be provided with air vents, filters, etc. to ensure ventilation and heat dissipation effects. Adjustments can be made according to specific usage conditions. The spotlight body 8 can be used for emergency lighting, and the single use time is not long.

[0047] Reference Figure 7 As shown in FIG, a through slot 14 is provided on the protective belt 13, and the through slot 14 does not pass through the side edge of the protective belt 13, thereby ensuring the stability of the overall structure of the protective belt 13 during use.

[0048] When the through groove 14 corresponds to the open end of the protective box 5, it does not affect the spotlight body 8 from providing light source to the outside; and when it rains, the top of the protective belt 13 extends outward, and the protective belt 13 (not the position of the through groove 14) covers the upper position of the spotlight body 8, and the through groove 14 corresponds to the light source end of the spotlight body 8, achieving a rainproof effect without affecting the provision of light source to the outside.

[0049] After the spotlight body 8 is recovered, the protective tape 13 closes the open end of the protection box 5 , thereby protecting the spotlight body 8 inside the protection box 5 to prevent it from being affected by dust and the like.

[0050] Reference Figure 3 、 Figure 4 As shown in the figure, in order to achieve enclosure on both sides of the protective belt 13 when the top end of the protective belt 13 extends outward, triangular plates 7 are provided on both sides of the protective belt 13, and the triangular plates 7 are in the shape of an inverted triangle. Recovery grooves 6 are provided on both sides of the open end of the protective box 5, and the triangular plates 7 are slidably set in the corresponding recovery grooves 6.

[0051] A limit rod 28 is provided between the two triangular plates 7. The two ends of the limit rod 28 are respectively rotatably connected to the two triangular plates 7 so that the two triangular plates 7 can move synchronously. When the top end of the protective belt 13 extends outward, the triangular plate 7 extends synchronously from the recovery groove 6 to enclose both sides of the protective belt 13.

[0052] Reference Figure 5 As shown in the figure, in order to realize the control of the protective belt 13, a first rotating shaft 9 is rotatably connected to the bottom end of the protective box 5, and the first rotating shaft 9 is close to the open end of the protective box 5. A second rotating shaft 10 is provided at the bottom end of the protective box 5, and a sliding groove 15 for the second rotating shaft 10 to extend into is provided on the inner wall of the protective box 5. The second rotating shaft 10 can both rotate inside the sliding groove 15 and slide inside the sliding groove 15.

[0053] The top of the protective box 5 is rotatably connected to the third rotating shaft 11, and the third rotating shaft 11 is located above the slide groove 15. A fourth rotating shaft 12 is arranged between the two triangular plates 7. There are two fourth rotating shafts 12. The two fourth rotating shafts 12 are rotatably connected to the two triangular plates 7 respectively. There is a certain gap between the two fourth rotating shafts 12, and the gap size is appropriate so as not to affect the stability of the protective belt 13. The first rotating shaft 9, the second rotating shaft 10, the third rotating shaft 11 and the fourth rotating shaft 12 are connected through the protective belt 13.

[0054] There is a gap between the limiting rod 28 and the fourth rotating shaft 12 for the protection belt 13 to pass through, and the limiting rod 28 is attached to the outer ring of the protection belt 13 without affecting the rotation of the protection belt 13, while ensuring the stability of the protection belt 13 in use.

[0055] Reference Figure 4 、 Figure 7 As shown in the figure, a motor 22 is fixedly connected to the outer wall of the protective box 5, and the third rotating shaft 11 is fixedly connected to the driving shaft of the motor 22. The motor 22 drives the third rotating shaft 11 to rotate, and with the cooperation of the first rotating shaft 9, the second rotating shaft 10, the third rotating shaft 11 and the fourth rotating shaft 12, the protective belt 13 rotates to adjust the position of the through slot 14.

[0056] Reference Figure 5、 Figure 8 As shown in , the fourth rotating shaft 12 is rotatably connected to a connecting bar 16, and one end of the connecting bar 16 away from the fourth rotating shaft 12 is rotatably connected to the second rotating shaft 10. The connecting bar 16 is provided so that the second rotating shaft 10 and the fourth rotating shaft 12 can move synchronously without affecting the rotation of the second rotating shaft 10 and the fourth rotating shaft 12.

[0057] Reference Figure 3 、 Figure 7 As shown in the figure, a connecting rod 17 is fixedly connected to the connecting bar 16, and the spotlight body 8 is installed on the connecting rod 17. When the connecting bar 16 moves toward the open end of the protection box 5, the connecting rod 17 drives the spotlight body 8 to move synchronously toward the open end of the protection box 5, and the light source end of the spotlight body 8 extends out of the protection box 5.

[0058] By setting structures such as connecting strips and connecting rods, the distribution shape of the protective belt 13 is adjusted to achieve switching of functions such as rain protection and closure, and the protective belt and the spotlight body can be synchronously extended and retracted.

[0059] Taking into account that the distribution shape of the protective belt 13 will change when the top end of the protective belt 13 extends outward, a tensioning assembly for tensioning the protective belt 13 is provided in the inner circle of the protective belt 13. The tensioning assembly includes a tensioning frame 18, an elastic telescopic rod 19, a tensioning roller 27 and a support plate 20. The tensioning roller 27 is rotatably set on the tensioning frame 18, and the tensioning roller 27 abuts against the inner circle of the protective belt 13. The support plate 20 is fixedly connected to the inner wall of the protective box 5, the fixed end of the elastic telescopic rod 19 is fixedly connected to the support plate 20, and the tensioning frame 18 is fixedly connected to the telescopic end of the elastic telescopic rod 19.

[0060] When the connecting bar 16 moves toward the open end of the protection box 5, the top end of the protective belt 13 extends outward. At this time, the connecting bar 16 drives the second rotating shaft 10 to move inside the slide groove 15 toward the open end of the protection box 5. The protective belt 13 is squeezed and contracted by the elastic telescopic rod 19 through the tensioning roller 27 and the tensioning frame 18, so that the protective belt 13 remains in a tensioned state; the motor 22 drives the third rotating shaft 11 to rotate, and with the cooperation of the first rotating shaft 9, the second rotating shaft 10, the third rotating shaft 11 and the fourth rotating shaft 12, the protective belt 13 is able to rotate; and when the connecting bar 16 is retracted toward the inside of the protection box 5, the top end of the protective belt 13 is retracted inward. At this time, the second rotating shaft 10 is reset inside the slide groove 15, and the reset elastic force of the elastic telescopic rod 19 causes the tensioning roller 27 to be squeezed on the inner ring of the protective belt 13, so that the protective belt 13 continues to remain in a tensioned state and the protective belt 13 can still rotate.

[0061] The provision of structures such as a tensioning assembly enables the protective belt 13 to maintain a tensioned state when being extended and retracted, thereby facilitating the control of the rotation of the protective belt 13 and the adjustment of the position of the through slot 14 .

[0062] At the same time, the tensioning assembly cooperates with the limiting rod 28 to prevent the protective belt 13 from wrinkling at the two fourth rotating shafts 12 .

[0063] In actual use, the two triangular plates 7 are controlled to extend synchronously from the corresponding recovery slots 6, the connecting strip 16 moves toward the open end of the protection box 5, and the top end of the protection belt 13 extends outward. At this time, the protection belt 13 is distributed in a trapezoidal shape, and the top end is wide.

[0064] At the same time, the spotlight body 8 moves synchronously toward the open end of the protection box 5, and the light source end of the spotlight body 8 extends out of the protection box 5, so as to provide light source outward.

[0065] The connecting bar 16 drives the second rotating shaft 10 to move inside the sliding groove 15 toward the open end of the protection box 5, and with the cooperation of the tensioning component, the protection belt 13 remains in a tensioned state.

[0066] The motor 22 is started, and the motor 22 drives the third rotating shaft 11 to rotate. Under the cooperation of the first rotating shaft 9, the second rotating shaft 10, the third rotating shaft 11 and the fourth rotating shaft 12, the protective belt 13 rotates to adjust the position of the through slot 14.

[0067] When the through slot 14 corresponds to the open end of the protection box 5 (refer to Figure 5 ), does not affect the spotlight body 8 providing light source outward.

[0068] If it rains during the use of the spotlight body 8, refer to Figure 5 , the protective belt 13 rotates counterclockwise, and the protective belt 13 (not the through groove 14 position) covers the position above the spotlight body 8. The two triangular plates 7 respectively block the two sides of the protective belt 13, and the through groove 14 corresponds to the light source end of the spotlight body 8, achieving a rainproof effect, reducing the impact of rain on the spotlight body 8, and does not affect the provision of light source to the outside.

[0069] When use is finished, the two triangular plates 7 are controlled to be synchronously recovered into the corresponding recovery slots 6 , and the connecting strips 16 and the protective belts 13 are reset to the inside of the protection box 5 .

[0070] At the same time, the spotlight body 8 is reset to the inside of the protection box 5 .

[0071] During the above process, the connecting bar 16 drives the second rotating shaft 10 to move inside the sliding groove 15 toward the open end of the protection box 5, and with the cooperation of the tensioning assembly, the protection belt 13 remains in a tensioned state.

[0072] Start the motor 22, which drives the third rotating shaft 11 to rotate. With the cooperation of the first rotating shaft 9, the second rotating shaft 10, the third rotating shaft 11 and the fourth rotating shaft 12, the protective belt 13 rotates. The protective belt 13 closes the open end of the protective box 5, and the through groove 14 is staggered with the open end of the protective box 5, so that the spotlight body 8 can be protected inside the protective box 5 to avoid being affected by the external environment.

[0073] The present invention achieves rainproof and closed effects by setting structures such as triangular plates 7 and protective belts 13, and utilizing the movement and rotation of the protective belts 13, thereby reducing the impact of rain on the spotlight body 8 without affecting the spotlight body 8 providing light source outward, thereby improving the use efficiency of energy-saving LED spotlights.

[0074] In order to control the position of structures such as the triangle plate 7, a control component is provided on the outside of the protective box 5 to drive the triangle plate 7, the spotlight body 8, and the protective belt 13 to extend synchronously. The control component includes an electric push rod 21, and the fixed end of the electric push rod 21 is fixedly connected to the outer wall of the protective box 5. One of the triangle plates 7 is fixedly connected to the telescopic end of the electric push rod 21.

[0075] Specifically, the telescopic end of the electric push rod 21 is controlled to extend, and with the cooperation of the limit rod 28, the two triangular plates 7 and other structures are driven to extend outward; and the telescopic end of the electric push rod 21 is controlled to retract, and with the cooperation of the limit rod 28, the two triangular plates 7 and other structures are driven to retract.

[0076] Considering that the spotlight body 8 is extended and dust is easily left on the light source end during use, in order to automatically wipe the light source end of the spotlight body 8, a cotton wipe 23 for wiping the light source end of the spotlight body 8 is adhered to the inner circle of the protective belt 13 using a traceless adhesive. The cotton wipe 23 is provided with a first oblique cut 24 and a second oblique cut 25. Figure 5 As shown in FIG, the first oblique cut 24 and the second oblique cut 25 are both located at an end of the cotton wiper 23 close to the fourth rotating shaft 12 .

[0077] The cotton wipe 23 may be, but is not limited to, an antistatic microfiber wipe, which has antistatic and antibacterial functions, is not prone to shedding, is highly durable, and is suitable for multiple uses.

[0078] The cotton wipe 23 can pass through the gap between the two fourth rotating shafts 12.

[0079] When you are ready to recycle after use, refer to Figure 5 , the control motor 22 drives the protective belt 13 to rotate counterclockwise. When the cotton wipe 23 contacts the light source end of the spotlight body 8, the light source end of the spotlight body 8 can be wiped and cleaned, and the second oblique cut 25 makes it easier for the cotton wipe 23 to quickly enter between the inner circle of the protective belt 13 and the spotlight body 8.

[0080] After wiping many times, the protective belt 13 rotates counterclockwise, and the first bevel cut 24 contacts the first rotating shaft 9. As the protective belt 13 continues to rotate, a tear is formed at the first bevel cut 24, and the cotton wipe 23 automatically falls off from the inner circle of the protective belt 13. The fallen cotton wipe 23 is limited by the first rotating shaft 9 and is located in the inner circle of the protective belt 13 and at the bottom end of the protective box 5, and is subsequently taken out by the operator.

[0081] Two or more cotton wipes 23 can be provided, and there is a certain distance between two adjacent cotton wipes 23. After one of the cotton wipes 23 has been used for a certain period of time, the other one can be used to extend the replacement time.

[0082] A cotton wipe 23 and other structures are provided, and the protective belt 13 is rotated to wipe the light source end of the spotlight body 8, and the cotton wipe 23 can be automatically detached, further improving the use efficiency of the energy-saving LED spotlight.

[0083] The single motor 22 is used to drive the protective belt 13 to rotate, thereby achieving the effects of rain protection, closure, and automatic wiping, improving energy utilization efficiency, reducing overall energy consumption, and achieving energy-saving effects.
