[0065] Example 1

[0066] Please refer to Figure 1-11 The present invention protects a street lamp, which has a lamp body 1 and a supporting column 2; the upper end of the supporting column 2 is fixed to the lower end surface of the lamp body 1, and the lower end surface of the supporting column 2 is fixed to the supporting surface; the lamp body 1 has a light source 11; a mounting groove 12 is provided on the bottom surface of the lamp body 1, and a solar panel 3 is arranged in the mounting groove 12; a through groove 13 is provided on the outer wall of the lamp body 1, and the through groove 13 extends into the lamp body 1 and is connected with the mounting groove 12, and the lower end of the through groove 13 extends out of the lower end surface of the lamp body 1; a accommodating chamber 15 is also provided in the lamp body 1, and a plurality of connecting grooves 14 are provided on the inner wall of the accommodating chamber 15, and the connecting grooves 14 extend horizontally outward into the mounting groove 12; a mounting chamber 21 is provided in the supporting column 2, and the mounting chamber 21 extends upward and is connected with the accommodating chamber 15.

[0067] It should be noted that the number of the through slots 13 , the mounting slots 12 and the connecting slots 14 are the same.

[0068] The solar panel 3 has a first end surface 31 and a second end surface 32 . A solar chip is disposed on the first end surface 31 , and the solar chip converts solar energy into electrical energy. A photoluminescent material is disposed on the second end surface 32 , and the photoluminescent material may be fluorescent powder.

[0069] The solar panel 3 has multiple states, see Fig.10In the first state, the solar panel 3 is hidden in the mounting groove 12, which can prevent the solar panel 3 from being damaged in extreme weather conditions, such as hail, heavy snow, etc., and can also prevent the solar panel 3 from being separated from the lamp body 1 due to strong winds, heavy rain or snow accumulation. Figure 1 , Figure 2 In the second state, the solar panel 3 extends out from the installation groove 12 and the through groove 13, and the solar panel 3 folds outward around its rotation center (the rotation center is the axis of the rotation shaft that rotates the solar panel 3 and the connecting rod 53), so that the multiple solar panels 3 form a blooming flower shape. At this time, the solar chip on the first end surface 31 can absorb solar energy and convert solar energy into electrical energy.

[0070] Focus on reference Figure 1 , Figure 4 , Fig.10 As a preferred solution, the lamp body 1 of this solution has a prism and a pyramid, and the pyramid is located above the prism; accordingly, the accommodating chamber 15 also has a prism-shaped space and a pyramid-shaped space; adopting this shape, first, the present invention has a beautiful appearance; second, it can form a gap outside the lamp body 1, and when the solar panel 3 is in the second state, it can receive more light; third, through the pyramid-shaped space formed in the accommodating chamber 15, the linkage structure 5 and the first supporting structure 6 have enough space to move; fourth, the top pyramid has multiple inclined surfaces, which can prevent rain and snow from staying on the top of the lamp body 1.

[0071] Focus on reference Figure 4 , Figure 6 The present invention further has a guide structure 4, which is used to guide the movement of the solar panel 3; the guide structure 4 includes: a guide groove 41 and a guide column 42, the guide column 42 is arranged on one side of the solar panel 3, the guide groove 41 is arranged on the installation groove 12 and the through groove 13, and the guide column 42 is restricted to slide in the guide groove 41; the guide groove 41 includes a first section 411 and a second section 412 connected to each other. In this solution, the first section 411 is arranged in the vertical direction, the lower end of the first section 411 is connected to the second section 412, and the second section 412 is arranged horizontally.

[0072] As a preferred solution, it also includes a third section 413, which is connected to the end of the second section 412 away from the first section 411, and the distance from its end close to the second section 412 to the horizontal plane is smaller than the distance from its end away from the second section 412 to the horizontal plane.

[0073] It should be noted that the center line of the third section 413 is an arc or an inclined straight line.

[0074] It should be noted that the first section 411 and the second section 412 , as well as the second section 412 and the third section 413 , are transitioned through circular arcs.

[0075] It should be noted that one solar panel 3 is provided with two sets of guide structures 4 ; that is, guide columns 42 are provided on both sides of the same solar panel 3 , and correspondingly, a pair of guide grooves 41 are symmetrically provided on the side walls of the mounting groove 12 and the through groove 13 .

[0076] It should be noted that, in this solution, the number of guide posts 42 on one side of the solar panel 3 is multiple, preferably two.

[0077] Focus on reference Figure 2 , Figure 4 , Figure 6 , Fig.11 The present invention further has a linkage structure 5, which is used to realize the linkage of multiple solar panels 3; the linkage structure 5 includes a linear drive member 51, a linkage seat 52 and a connecting rod 53; the linear drive member 51 is arranged in the installation chamber 21, and the output end of the linear drive member 51 extends upward into the accommodating chamber 15; the linkage seat 52 is fixedly arranged at the output end of the linear drive member 51, and the linkage seat 52 is located in the accommodating chamber 15; one end of the connecting rod 53 is rotatably connected to the linkage seat 52 ( Fig.11 The linkage seat 52 shown in the figure has a through slot, an optical axis is arranged in the through slot, and the connecting rod 53 is rotatably connected to the outer wall of the optical axis). The other end of the connecting rod 53 passes through the connecting slot 14 and is rotatably connected to the solar panel 3 ( Figure 6 The solar panel 3 is shown with a rotating shaft in the middle, and the connecting rod 53 is rotatably connected to the outer wall of the rotating shaft).

[0078] It should be noted that the connecting rod 53 is tilted, and when the solar panel is in any state, the height of the hinge between the connecting rod 53 and the linkage seat 52 is always greater than the height of the hinge between the connecting rod 53 and the solar panel 3.

[0079] It should be noted that, in the present embodiment, the linear drive member 51 may be any one of an electric telescopic rod, a hydraulic cylinder, and a pneumatic cylinder, and an electric telescopic rod is preferred.

[0080] When the linkage structure 5 is used specifically (taking the process of the solar panel 3 switching from the first state to the second state as an example), the linear drive member 51 moves downward to pull the linkage seat 52 to move, and the linkage seat 52 moves downward to drive the solar panel 3 to move downward through the connecting rod 53, and the guide column 42 moves in the first section 411, so that the solar panel 3 moves vertically downward; when multiple guide columns 42 enter the second section 412, the solar panel 3 flips under the push of the connecting rod 53 until the solar panel 3 is in a horizontal state, and the first end surface 31 of the solar panel 3 faces vertically upward; further, when at least one guide column 42 enters the third section 413, the end of the solar panel 3 away from the linkage seat 52 is tilted upward, so that the solar panel 3 has better energy capture efficiency in the second state.

[0081] It should be noted that by optimizing the tilt angle and direction of the solar panel 3, its energy capture efficiency can be significantly improved, thereby improving the performance of the entire solar energy system (the tilt angle of the solar panel is crucial to its efficiency, and the optimal tilt angle in the northern hemisphere is 20 to 30 degrees in summer and 30 to 40 degrees in winter).

[0082] It should be noted that, in order to further improve the energy capture efficiency of the solar panel 3 , a reflective surface may be provided on the outer wall of the prism of the lamp body 1 .

[0083] It should be noted that the light source 11 of the present invention is preferably an LED lamp bead, and the number of the LED lamp beads is multiple.

[0084] Example 2

[0085] In order to improve the stability of the solar panel 3 in the first state, the following improvements are made.

[0086] Focus on reference Figure 4 , Figure 5 The present invention has a first supporting structure 6, which includes a sleeve 61 and a sleeve 62; wherein the sleeve 61 is a hollow structure with one end open, a connecting shaft is fixedly provided on the upper end surface of the linkage seat 52, the sleeve 61 is rotatably connected to the outside of the connecting shaft through a bearing, and a supporting column 63 is provided on the outer wall of the sleeve 61.

[0087] The sleeve 62 is fixed on the top of the accommodating chamber 15, and a guide groove 64 is fixedly provided on the inner wall of the sleeve 62. The supporting column 63 can move in the guide groove 64. The guide groove 64 includes a first guide section 641, a second guide section 642, a supporting section 645, a third guide section 643, a fourth guide section 644 and a fifth guide section 646 which are connected in sequence; wherein the lower end of the first guide section 641 extends out of the lower end surface of the sleeve 62, and the upper end of the first guide section 641 extends upward along the inner wall of the sleeve 62 obliquely; the upper end of the second guide section 642 is connected to the upper end of the first guide section 641, and the second guide section 643 is connected to the upper end of the first guide section 641. The lower end of the guide section 642 extends obliquely downward along the inner wall of the sleeve 62 and is connected with the supporting section 645; the supporting section 645 is located between the second guide section 642 and the third guide section 643; the lower end of the third guide section 643 extends obliquely downward along the inner wall of the sleeve 62 and is connected with the supporting section 645, and the upper end of the third guide section 643 is connected with the upper end of the fourth guide section 644; the lower end of the fourth guide section 644 extends obliquely downward along the inner wall of the sleeve 62 and is connected with the upper end of the fifth guide section 646; the lower end of the fifth guide section 646 extends obliquely downward and extends into the first guide section 641.

[0088] It should be noted that the first guide segment 641 , the second guide segment 642 , the supporting segment 645 , the third guide segment 643 and the fourth guide segment 644 are connected end to end in the circumferential direction of the sleeve 62 .

[0089] It should be noted that only one supporting column 63 is disposed in a single guide groove 64 .

[0090] It should be noted that, in the present solution, one supporting column 63 and one guiding groove 64 form a group. The present invention may be provided with multiple groups of supporting columns 63 and guiding grooves 64, preferably two groups.

[0091] It should be noted that the electric telescopic rod in this solution needs to be equipped with a PLC chip to control the travel of the electric telescopic rod.

[0092] It should be noted that a guide surface 621 is provided at the connection between the first guide section 641 and the upper wall of the fifth guide section 646 to prevent the supporting column 63 from sliding into the fifth guide section 646 when entering the first guide section 641 .

[0093] It should be noted that arc transition is adopted at the connection points among the first guide segment 641 , the second guide segment 642 , the supporting segment 645 , the third guide segment 643 , the fourth guide segment 644 and the fifth guide segment 646 .

[0094] It should be noted that the connection between the lower wall of the first guide section 641 and the lower wall of the second guide section 642 and the connection between the upper wall of the first guide section 641 and the upper wall of the second guide section 642 are staggered in the vertical direction; the corner of the upper wall of the supporting section 645 and the corner of the lower wall of the supporting section 645 are staggered in the vertical direction; the connection between the upper wall of the third guide section 643 and the upper wall of the fourth guide section 644 and the connection between the lower wall of the third guide section 643 and the lower wall of the fourth guide section 644 are staggered in the vertical direction; in this way, it can be ensured that the supporting column 63 moves in a predetermined direction.

[0095] In this way, through the cooperation between the supporting column 63 and the supporting section 645 , when the linear drive member 51 fails, the supporting column 63 is supported by the supporting section 645 , so that the solar panel 3 can maintain the first state and will not fall out of the installation groove 12 .

[0096] When the first supporting structure 6 is used specifically (taking the solar panel 3 in the first state as an example, the supporting column 63 is located in the supporting section 645 at this time), the linear drive member 51 pushes the linkage seat 52 upward to move, the supporting column 63 moves upward and hits the upper wall of the third guide section 643, the linear drive member 51 continues to push the supporting column 63 upward, the supporting column 63 rotates horizontally under the guidance of the third guide section 643, so that the supporting column 63 can fit the upper wall of the third guide section 643 and continue to move upward; when the supporting column 63 moves to the third guide section After the connection between the upper wall 643 and the upper wall of the fourth guide section 644, the linear drive member 51 pulls the linkage seat 52 downward to move, so that the supporting column 63 moves vertically downward and contacts the lower wall of the fourth guide section 644, and then moves downward under the guidance of the lower wall of the fourth guide section 644. After disengaging from the fourth guide section 644, the supporting column 63 moves vertically downward and contacts the lower wall of the fifth guide section 646, and then slides into the first guide section 641 under the guidance of the lower wall of the fifth guide section 646, and then slides out of the first guide section 641.

[0097] Example 3

[0098] In order to improve the stability of the solar panel in the second state, the following improvements are made.

[0099] refer to Figure 6 , Figure 7 , Figure 8 , Fig. 9 A second supporting structure 8 is also provided, and the second supporting structure 8 includes a connecting hole 81 and a connecting hemisphere 82. The connecting hemisphere 82 is provided on the guide column 42, and the connecting hole 81 is provided in the guide groove 41. When the solar panel 3 is in the second state, the connecting hemisphere 82 extends into the connecting hole 81 to fix the solar panel 3 relative to the guide groove 41. On the one hand, the solar panel 3 can maintain the second state, and on the other hand, it can also share the force exerted on the connecting rod 53.

[0100] It should be noted that both the connecting hemisphere 82 and the connecting hole 81 are spherical cap-shaped, so that when the solar panel 3 leaves the second state, the connection state between the connecting hemisphere 82 and the connecting hole 81 can be released through the guidance of the spherical surface.

[0101] As a preferred solution, refer to Fig. 9 The connecting hemisphere 82 is elastically installed in the guide column 42 through a spring. Specifically, a step hole is set in the guide column 42, and a retaining ring is integrally formed on the connecting hemisphere 82. The outer diameter of the retaining ring is smaller than the diameter of the large hole of the step hole, and the outer diameter of the retaining ring is larger than the diameter of the small hole of the step hole, thereby fixing the connecting hemisphere 82 relative to the step hole. A spring is set in the large hole of the step hole, and the spring acts on the retaining ring to push the connecting hemisphere 82 to move out of the step hole.

[0102] Example 4

[0103] The arrangement position of the light source 11 in the present invention is described in detail.

[0104] refer to Fig.10 The light source 11 is arranged at one end of the mounting groove 12 extending into the lamp body 1, a light-transmitting plate is arranged on the lamp body 1, and a light-transmitting groove 16 is arranged on the outer wall of the lamp body 1. The light-transmitting groove 16 extends horizontally along the outer wall of the lamp body 1 into the mounting groove 12, and the light-transmitting plate is installed in the light-transmitting groove 16; when the solar panel 3 is in the first state, the second end surface 32 blocks the light source 11, and can block most of the light emitted by the light source 11, and only a small amount of light is emitted from the gap between the solar panel 3 and the mounting groove 12 to exit the mounting groove 12.

[0105] Therefore, in this embodiment, the solar panel 3 can reduce the brightness of the street lamp when in the first state, thereby reducing light pollution to nearby residents; in addition, since a photoluminescent material is provided on the second end surface 32, the photoluminescent material absorbs the light of the light source 11, and can emit light through the photoluminescent material after the light source 11 is cut off, thereby improving the endurance of the present invention.

[0106] When using it, follow these steps:

[0107] Step 1: During the day, adjust the position of the solar panel 3 so that the solar panel 3 is in the second state, converting solar energy into electrical energy and storing it in the battery;

[0108] Step 2: During the night time when the lighting demand is high, adjust the position of the solar panel 3 to prevent the solar panel 3 from blocking the light divergence;

[0109] Step 3: During the period of time when the lighting demand is low at night, the position of the solar panel 3 is adjusted so that the solar panel 3 is in the first state, and the solar panel 3 blocks the light to reduce the brightness of the street lamp. At the same time, the photoluminescent material on the second end surface 32 absorbs the light emitted by the light source 11;

[0110] Step 4: the battery is exhausted, the light source 11 is powered off, and the photoluminescent material on the second end surface 32 emits light to achieve lighting.

[0111] It should be noted that the light source 11 of the present solution may also be disposed in the accommodating chamber 15 .

[0112] Example 5

[0113] refer to Figure 4 , which is different from Embodiment 4 in that the light source 11 is arranged on the lower end surface of the lamp body 1 .

[0114] refer to Figure 3 The solar panel in this embodiment also has a third state. In the third state, a portion of the solar panel 3 is located below the lamp body 1 to form a lampshade.

[0115] When the solar panel 3 is in the third state, the lampshade composed of multiple solar panels 3 is arranged around the light source 11, and the photoluminescent material on the second end surface 32 can absorb a part of the light; in addition, due to the effect of the lampshade, the direction of the light can be changed, limiting the diffusion of light to the surrounding environment, and reducing the light pollution caused by light scattering to the surrounding residents.

[0116] When using it, follow these steps:

[0117] Step 1: During the day, adjust the position of the solar panel 3 so that the solar panel 3 is in the second state, converting solar energy into electrical energy and storing it in the battery;

[0118] Step 2: During the period of time when the lighting demand is high at night, the position of the solar panel 3 is adjusted so that the solar panel 3 is in the first state to prevent the light of the light source 11 from being blocked by the solar panel 3 during the emission process;
