[0055] In the solar LED lamp, the controller 80 can be a separate component independent of the battery device 20, the photovoltaic device 30 and the LED lamp 40, then the controller 80 is installed on the lamp pole 10, and the cable 61 electrically connected to the battery module 21 extends out to be electrically connected to the controller 80, and similarly, the photovoltaic device 30 and the controller 80, and the LED lamp 40 and the controller 80 are all electrically connected through cables.

[0056] like Figures 2 to 4 , Figures 6 to 8As shown, the battery box 22 of the solar LED lamp of the first embodiment includes a box body 223 and a box cover 224. The box body 223 includes an inner wall 2231, an outer wall 2232 and an annular bottom wall 2233. One end of the inner wall 2231 is connected to the inner edge of the annular bottom wall 2233, and one end of the outer wall 2232 is connected to the outer edge of the annular bottom wall 2233. The inner wall 2231, the outer wall 2232 and the annular bottom wall 2233 form an installation space 222. The inner wall 2231 surrounds a first through hole 2234, and the box cover 224 is provided with a second through hole 2241. After the battery module 21 is placed in the installation space 222 of the box body 223, the box cover 224 is sealed and covered on the box body 223, so that the installation space 222 forms a sealed space, and the second through hole 2241 and the first through hole 2234 are connected to form an axial through hole 221. Then, the second end of the lamp pole 10 is passed through the axial through hole 221, and the LED lamp 40 is mounted and fixed on the second end of the lamp pole 10, and the photovoltaic device 30 is mounted and fixed on the lamp pole 10 between the LED lamp 40 and the battery device 20, and then the LED lamp 40 and the controller 80, the battery module 21 and the controller 80, and the photovoltaic device 30 and the controller 80 are electrically connected. In this way, when there is sufficient sunlight during the day, the photovoltaic device 30 converts light energy into electrical energy and stores it in the battery module 21. At night, the solar LED lamp is started, and the electrical energy stored in the battery module 21 supplies power to the LED lamp 40, so that the LED lamp 40 emits light for illumination.

[0057] like Fig.10 and Fig.11 As shown, the box cover 224 is provided with a concentric first circumferential groove 2242 and a second circumferential groove 2243 on one side facing the box body 223. When the box cover 224 is sealed and covered on the box body 223, the other end of the inner wall 2231 is inserted into the first circumferential groove 2242, and the other end of the outer wall 2232 is inserted into the second circumferential groove 2243, wherein the first circumferential groove 2242 and the second circumferential groove 2243 are both filled with sealant. In this way, after the sealant is cured, the mutually covering position between the box cover 224 and the box body 223 forms a sealing arrangement, so that the installation space 222 forms a sealed space, which can be waterproof and dustproof.

[0058] And, if Figures 7 to 10 As shown, the box cover 224 is provided with a mounting hole 2247, and the cable 61 passes through the mounting hole 2247 and extends into the mounting space 222 to be electrically connected to the battery module 21. Figure 2 , Figure 3 , Figures 6 to 8 As shown, the cable 61 and the hole wall of the mounting hole 2247 are sealed by a seal 62 .

[0059] In the solar LED lamp of the first embodiment of the present application, Figure 4 , Figure 6 and Figure 8 As shown, the annular bottom wall 2233 is provided with a first connection portion 2235 on one side away from the box cover 224, and the first connection portion 2235 is provided with a first threaded hole 2236. The solar LED lamp also includes a first bolt 51, which is screwed into the first threaded hole 2236 and tightens the lamp pole 10. Further, as Figure 2 , Figure 3 , Figures 5 to 7 , Fig. 9 and Fig.11 As shown, the box cover 224 is provided with a second connection portion 2244 on the side away from the box body 223, and the second connection portion 2244 is provided with a second threaded hole 2245. The solar LED lamp also includes a second bolt 52, which is screwed into the second threaded hole 2245 and presses against the lamp pole 10. After the second end of the lamp pole 10 passes through the axial through hole 221, the first bolt 51 and the second bolt 52 are screwed into the first connection portion 2235 and the second connection portion 2244 respectively, and the first bolt 51 and the second bolt 52 press against the lamp pole 10, so that the battery device 20 as a whole can remain stable relative to the lamp pole 10, and the battery device 20 will not shake relative to the lamp pole 10 even if it is subjected to external force.

[0060] like Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, a first reinforcing rib 2237 is provided on the side of the annular bottom wall 2233 away from the box cover 224, and the first reinforcing rib 2237 is connected between the annular bottom wall 2233 and the first connecting portion 2235. The first reinforcing rib 2237 improves the strength of the annular bottom wall 2233 and the first connecting portion 2235.

The second reinforcing rib 2246 improves the strength of the box cover 224 and the second connecting portion 2244.

[0061] In the solar LED lamp of the first embodiment of the present application, the box body 223 is an integrally formed component, and the box cover 224 is an integrally formed component. Among them, the box body 223 and the box cover 224 are both die-casted with aluminum material, which is light and has sufficient strength. In addition, the lamp pole 10 gradually decreases in diameter along the direction from the first end to the second end. After the second end of the lamp pole 10 passes through the axial through hole 221, when the battery device 20 reaches a suitable position (that is, the aperture of the axial through hole 221 is equal to the diameter of the lamp pole 10), the battery device 20 will be clamped on the lamp pole 10. In the solar LED lamp of the first embodiment, after the solar LED lamp is assembled and the first end of the lamp pole 10 is installed to the fixed installation position, due to the height of the lamp pole 10 and the LED lamp 40 is fixedly installed on the second end of the lamp pole 10, and the battery device 20 must be detached from the lamp pole from the second end of the lamp pole 10, the solar LED lamp increases the difficulty of the battery device 20 being stolen and improves the anti-theft level.

[0062] In other embodiments, the box body 223 and the box cover 224 may be either one or the other integrally formed.

[0063] Furthermore, the cross-section of the battery box 22 of the solar LED lamp perpendicular to its axis is in the shape of a circle or a regular polygon. Preferably, the cross-section of the battery box 22 perpendicular to its axis is in the shape of a regular hexagon.

[0064] like Figure 1 As shown, the photovoltaic device 30 includes a plurality of photovoltaic panels 31, and the plurality of photovoltaic panels 31 are arranged in sequence around the lamp pole 10. This improves the light collection capacity of the photovoltaic device 30, thereby increasing the rate of converting light energy into electrical energy and the charging rate of the battery module 21.

[0065] Embodiment 2:

[0066] Compared with the solar LED lamp of the first embodiment, the solar LED lamp of the second embodiment has the following differences.

Battery modules 21 are installed in both the first space 2203 and the second space 2204. Furthermore, the battery module 21 in the first space 2203 is connected in parallel or in series with the battery module 21 in the second space 2204. In the solar LED lamp of the second embodiment, the battery module 21 in the first space 2203 is connected in parallel with the battery module 21 in the second space 2204 via a parallel connector 70.

[0068] Furthermore, when the battery device 20 is installed on the lamp pole 10, the first half box 2201 and the second half box 2202 are docked, so that the first half box 2201 and the second half box 2202 are combined to clamp the lamp pole 10. Then, the first cover 2207 and the second cover 2208 are locked by the third bolt 53. The first main box 2205 and the second main box 2206 are locked by the fourth bolt 54. In this way, the first half box 2201 and the second half box 2202 are fixed to the lamp pole 10 by a clamp.
