Description

Technical Field

[0001] The invention belongs to the field of lamps, and specifically provides a solar lamp. Background Art

[0002] Existing solar lights usually include a solar module, a bracket and a lighting module. The solar module is installed on the top of the bracket, and converts solar energy into electrical energy through a solar panel and stores it in a battery for nighttime lighting. The solar module is usually provided with a power supply terminal for electrical connection with the power receiving terminal of the lighting module to achieve power transmission. The lighting module is usually designed to be detachable to facilitate user replacement or maintenance.

[0003] In the prior art, the power supply terminal and the power receiving terminal of a solar lamp are usually electrically connected in the form of direct contact. However, since solar lamps are usually installed in outdoor environments and exposed to harsh conditions such as wind, sun, and rain for a long time, an oxide film is easily formed on the contact surface of the power supply terminal and the power receiving terminal. The presence of the oxide film will seriously affect the conductivity between the power supply terminal and the power receiving terminal, and even cause the solar lamp to fail to work properly.

[0004] In order to ensure the normal operation of the solar lamp, the prior art generally directly replaces the power supply terminal and the power receiving terminal, which is not only inconvenient to operate but also costly. Alternatively, the power supply terminal and the power receiving terminal are polished with tools such as sandpaper and grinding wheels, but since the power supply terminal and the power receiving terminal are small in structure, the operation is extremely inconvenient and may even damage other components of the solar lamp. Summary of the invention

[0005] One object of the present invention is to solve the problem that an oxide film is easily formed on the contact surface between the power supply terminal and the power receiving terminal in a solar lamp, thereby affecting the operation of the solar lamp.

[0006] To achieve the above object, the present invention provides a solar lamp, comprising:

[0007] Bracket;

[0008] A solar module is mounted on the top of the bracket and has a solar panel on its top side to convert solar energy into electrical energy; the solar module is provided with a receiving cavity with an opening on the bottom side, and a power supply terminal is provided on the top side of the receiving cavity; a slot is provided on one of the two opposite sides of the receiving cavity, and a buckle is provided on the other side;

[0009] A lighting module is adapted to the accommodating cavity and has a power receiving terminal on the top side. One of the two opposite ends of the lighting module is provided with an insertion protrusion, and the other end is provided with a card slot, so that the insertion protrusion is first inserted into the slot and then the lighting module is rotated to a position where the buckle is embedded in the card slot, so that the lighting module is embedded in the accommodating cavity;

[0010] Among them, one of the power supply terminal and the power receiving terminal is set as a telescopic elastic structure, so that the power supply terminal and the power receiving terminal first abut and then slide relative to each other during the rotation of the lighting module, so that the contact surface of the power supply terminal and the power receiving terminal is worn, and the oxide film can be removed.

[0011] Optionally, the buckle includes an operating portion, so that the buckle can be moved out of the slot by operating the operating portion, so that the lighting module can be rotated out of the receiving slot, and thus the contact surfaces of the power supply terminal and the power receiving terminal are worn again.

[0012] Optionally, the power supply terminal is configured as a telescopic elastic structure, and an area of ​​a surface of the power receiving terminal in contact with the power supply terminal is larger than an area of ​​a surface of the power supply terminal in contact with the power receiving terminal.

[0013] Optionally, the solar module is provided with a terminal cavity on the top side of the accommodating cavity, and the power supply terminal is arranged in the terminal cavity; the top of the lighting module is provided with a plug and a sealing ring sleeved on the outer circumference of the plug, and the power receiving terminal is arranged on the plug; the size of the plug is smaller than the size of the terminal cavity to ensure that the plug can be inserted into or pulled out of the terminal cavity as the lighting module rotates; the sealing ring is interference fit with the terminal cavity to seal the terminal cavity.

[0014] Optionally, the bracket is a rectangular tube column as a whole, and an opening is respectively provided on two opposite side walls of the bracket; a conical structure is provided at the inner bottom of the bracket, and the conical structure includes two opposite inclined plates, each of which corresponds to one of the openings, so that the light emitted by the lighting module can be reflected out of the bracket through the inclined plates.

[0015] Optionally, an outwardly protruding annular stop edge is provided on the top of the solar module; a portion of the solar module located at the bottom side of the annular stop edge is embedded in the bracket, and the annular stop edge abuts against the top end of the bracket.

[0016] Optionally, the portion of the solar module located at the bottom side of the annular stop edge is plugged into the bracket and is provided with at least one fixing groove; the bracket is provided with at least one threaded hole corresponding to the fixing groove, so that a screw can be screwed into the threaded hole and inserted into the fixing groove to fix the solar module and the bracket together.

[0017] Optionally, the fixing groove is a transversely extending rectangular groove, and the bottom wall of the rectangular groove has an inclined section inclined downward, so that the annular stop edge presses the top end of the bracket when the screw abuts against the inclined section.

[0018] Optionally, a main switch is provided on the portion of the solar module located at the bottom side of the annular stop edge; and / or, at least one function key is provided on the bottom surface of the solar module; and / or, the solar module also includes a battery; and a charging port and a power indicator light are provided on the bottom surface of the solar module.

[0019] Optionally, the bottom end of the bracket is used to be fixed to the ground so that the solar lamp can be used as a ground lamp.

[0020] Based on the foregoing description, those skilled in the art can understand that, in the aforementioned technical solution of the present invention, by making the lighting module mounted on the solar module in a rotating manner, and setting one of the power supply terminal and the power receiving terminal as a telescopic elastic structure, the power supply terminal and the power receiving terminal first abut and then slide relative to each other during the rotation of the lighting module, so that the contact surface of the power supply terminal and the power receiving terminal is worn, and the oxide film can be removed. Therefore, the solar lamp of the present invention can effectively remove the oxide film formed at least during the installation of the lighting module, ensuring the stability of the solar lamp during operation.

[0021] Furthermore, by operating the operating portion of the buckle to move the buckle out of the slot, the lighting module can be rotated out of the receiving slot, and thus the surfaces where the power supply terminal and the power receiving terminal contact each other are worn again, and the oxide film is removed again. That is, each time the lighting module is installed and removed, the surfaces where the power supply terminal and the power receiving terminal contact each other can be worn twice, and the oxide film can be removed twice. For this reason, the present invention can effectively remove the oxide film on the power supply terminal and the power receiving terminal by repeatedly installing and removing the lighting module several times, and the operation is more convenient.

[0022] It can be seen that the present invention adopts a new concept and uses a technical means that is completely different from the prior art. It not only removes the oxide film on the power supply terminal and the power receiving terminal, but also is relatively easy to operate.

[0052] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, a solar lamp 001 includes a bracket 100 , a solar module 200 and a lighting module 300 .

[0053] like Figures 1 to 4 As shown, the solar module 200 is installed on the top of the bracket 100 and a solar panel 210 is disposed on the top side thereof to convert solar energy into electrical energy.

[0054] like Figures 1 to 4 As shown, the lighting module 300 is installed at the bottom or bottom side of the solar module 200 , and the lighting module 300 is configured so that the light it emits is irradiated toward the inner bottom of the bracket 100 and is reflected by the bracket 100 .

[0055] like Figures 1 to 4 As shown, in some embodiments of the present invention, the bracket 100 is a rectangular tube column as a whole. In addition, an opening 101 is provided on at least one side wall of the bracket 100 so that the light emitted by the lighting module 300 can pass through the bracket 100 through the opening 101 .

[0056] like Figures 1 to 5As shown, in some embodiments of the present invention, a conical structure 110 is disposed at the inner bottom of the bracket 100. As can be seen from the figure, the tip of the conical structure 110 faces the lighting module 300, so that the conical structure 110 reflects the light emitted by the lighting module 300 out of the bracket 100.

[0057] Furthermore, an opening 101 is respectively provided on two opposite side walls of the bracket 100. The conical structure 110 includes two opposite inclined plates 111 and is in an inverted V shape as a whole. Moreover, each inclined plate 111 corresponds to an opening 101. That is, each opening 101 is aligned with an inclined plate 111.

[0058] from Figures 1 to 5 It can be seen from the figure that the height of the conical structure 110 is lower than the height of the opening 101 .

[0059] Of course, those skilled in the art may also make the height of the tapered structure 110 greater than or equal to the height of the opening 101 as required.

[0060] Furthermore, in some embodiments of the present invention, those skilled in the art may also polish the outer surface of the conical structure 110, or apply a reflective coating (such as white paint, transparent paint, reflective tape, etc.) on the outer surface of the conical structure 110 as needed to enhance the reflective effect of the conical structure 110, thereby enhancing the overall lighting effect of the solar lamp 001.

[0061] Furthermore, in some embodiments of the present invention, the bottom end of the bracket 100 can be fixed to the ground to use the solar lamp 001 as a ground lamp. Of course, those skilled in the art can also fix the bottom end of the bracket 100 to the wall as needed to use the solar lamp 001 as a wall lamp.

[0062] Of course, the user can place the bracket 100 on a table according to actual needs to use the solar lamp 001 as a table lamp; or place the bracket 100 on the ground to use the solar lamp 001 as a floor lamp.

[0063] like Figures 1 to 4 As shown, in some embodiments of the present invention, an outwardly protruding annular stop edge 220 is provided on the top of the solar module 200. The portion of the solar module 200 located at the bottom of the annular stop edge 220 is embedded in the bracket 100, and the annular stop edge 220 abuts against the top of the bracket 100. In this way, part of the structure of the solar module 200 can be shielded by the bracket 100, so that the processing accuracy of this part does not need to be too high, thereby reducing the production cost of the solar module 200.

[0064] Furthermore, the portion of the solar module 200 located at the bottom side of the annular stop edge 220 can be plugged into the bracket 100, so that the solar module 200 can be fixed to the bracket 100 by plugging, thereby achieving rapid fixation of the solar module 200 and the bracket 100.

[0065] Furthermore, the portion of the solar module 200 located at the bottom side of the annular stop edge 220 is configured to be conical, so as to facilitate insertion into the bracket 100 .

[0066] like Figures 1 to 3 As shown, in some embodiments of the present invention, a portion of the solar module 200 located at the bottom side of the annular stop edge 220 is provided with an outwardly protruding buckle structure 230 .

[0067] Correspondingly, a top end of the bracket 100 is provided with an avoidance gap 102 for avoiding the buckle structure 230 , so that the buckle structure 230 can be embedded in the avoidance gap 102 .

[0068] It is understood by those skilled in the art that by providing the hand-grip structure 230 on the solar module 200, providing the avoidance notch 102 on the bracket 100, and embedding the hand-grip structure 230 into the avoidance notch 102, the solar module 200 can be disassembled through the hand-grip structure 230 exposed to the outside after being installed on the bracket 100, which facilitates the disassembly operation of the user. In short, the user can first hold the hand-grip structure 230 with the thumb, and then quickly pull the solar module 200 off the bracket 100.

[0069] Furthermore, in other embodiments of the present invention, those skilled in the art may also set the hand-clasp structure 230 to be light-transmissive as needed, and set an infrared sensor therein to sense whether there are people around, and control the lighting module 300 to emit light when sensing that there are people. In other words, the hand-clasp structure 230 may not be used as a hand-clasp, but may be set as an infrared detection structure.

[0070] like Figure 1 , Figure 2 , Figures 6 to 8 As shown, in some embodiments of the present invention, at least one fixing groove 201 is provided on the portion of the solar module 200 located at the bottom side of the annular stop edge 220 .

[0071] like Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments of the present invention, the bracket 100 is provided with at least one threaded hole 103 corresponding to the fixing groove 201 .

[0072] like Figure 3 and Figure 4As shown, after the solar module 200 and the bracket 100 are plugged together, the screw 400 can be screwed into the threaded hole 103 and inserted into the fixing groove 201 to fix the solar module 200 and the bracket 100 together to prevent the solar module 200 and the bracket 100 from being accidentally separated.

[0073] like Figures 6 to 8 As shown, in some embodiments of the present invention, the fixing groove 201 is a transversely extending rectangular groove, and the bottom wall of the rectangular groove has an inclined section 2011 inclined downward, so that the annular stop edge 220 presses the top of the bracket 100 when the screw 400 abuts against the inclined section 2011.

[0074] like Figure 6 and Figure 7 As shown, in some embodiments of the present invention, the part of the solar module 200 located at the bottom side of the annular stop edge 220 is provided with a main switch 241, and the main switch 241 is used to control whether the solar lamp 001 works. That is, by operating (specifically pressing) the main switch 241, it can be controlled whether the solar module 200 supplies power to the lighting module 300.

[0075] Continue reading Figure 6 and Figure 7 In some embodiments of the present invention, the solar module 200 further includes a battery 244 and a battery compartment cover 243 for covering the battery 244, so that the user can install, remove and replace the battery 244. A charging port 245 is provided on the bottom surface of the solar module 200, so that when the sunlight is insufficient (for example, on a rainy day) and the battery 244 cannot be fully charged by the solar panel 210 for nighttime use, or when the battery 244 runs out of power at night, the user can charge the battery 244 through the charging port 245 and supply power to the lighting module 300.

[0076] Continue reading Figure 6 and Figure 7 In some embodiments of the present invention, the solar module 200 may further include a charging plug 246 to open and shield the charging port 245 , thereby ensuring the charging function of the charging port 245 while preventing dust accumulation at the charging port 245 .

[0077] Continue reading Figure 6 and Figure 7 In some embodiments of the present invention, a power indicator light 242 may be further provided on the bottom surface of the solar module 200 . The power indicator light 242 is used to indicate the power level of the battery 244 , so that the user can intuitively understand the power level of the battery 244 .

[0078] Continue reading Figure 6 and Figure 7In some embodiments of the present invention, at least one function key 250 may be further provided on the bottom surface of the solar module 200. The at least one function key 250 may specifically include a color temperature adjustment key 251, a power adjustment key 252, and a mode switching key 253. The color temperature adjustment key 251 is used to adjust the color temperature of the light emitted by the lighting module 300, the power adjustment key 252 is used to adjust the luminous power of the lighting module 300, and the mode switching key 253 is used to switch the working mode of the solar module 200.

[0079] It can be understood by those skilled in the art that by setting the main switch 241 at the part of the solar module 200 located at the bottom side of the annular stop edge 220, at least one function key 250, a charging port 245 and a power indicator light 242 are set on the bottom surface of the solar module 200, which are blocked by the bracket 100, the solar lamp 001 is more concise and more beautiful as a whole.

[0080] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the lighting module 300 is detachably connected to the solar module 200 to facilitate users to disassemble, repair and replace the lighting module 300.

[0081] like Fig. 9 and Fig.10 As shown, in some embodiments of the present invention, the lighting module 300 may include a top shell 310, a bottom shell 320, and a light board 330 disposed between the top shell 310 and the bottom shell 320. The top shell 310 is used to connect the solar module 200. The bottom shell 320 is fixedly connected to the top shell 310, and the fixed connection may be snap-fit, screw-connected, bonded, etc. The bottom side wall of the bottom shell 320 as a whole or the position aligned with the lights on the light board 330 is made of a light-transmitting material. The light-transmitting material may be glass, plastic, acrylic, etc. The light board 330 may be provided with lights of one color, or may be provided with lights of two or more colors, so that the lighting module 300 can emit light of different colors by lighting lights of different colors.

[0082] like Figure 2 , Figures 6 to 8 As shown, in some embodiments of the present invention, the solar module 200 is provided with a receiving cavity 202 with a bottom opening to receive the lighting module 300. A slot 2021 is provided on one of the two opposite sides of the receiving cavity 202, and a buckle 261 is provided on the other side.

[0083] like Fig. 9 and Fig.10As shown, in some embodiments of the present invention, one of the two opposite ends of the lighting module 300 is provided with an insertion protrusion 301, and the other end is provided with a card slot 302. Specifically, the insertion protrusion 301 and the card slot 302 are both provided on the top shell 310. Of course, those skilled in the art may also provide at least one of the insertion protrusion 301 and the card slot 302 on the bottom shell 320 as needed.

[0084] like Figures 11 to 13 As shown, in the assembled state, the lighting module 300 is embedded in the accommodating cavity 202 , the insertion protrusion 301 is inserted into the slot 2021 , and the buckle 261 is embedded in the slot 302 , so as to fix the lighting module 300 to the solar module 200 .

[0085] like Figure 7 , Figure 8 and Fig.11 As shown, the buckle 261 is a retractable structure, and the solar module 200 also includes a locking spring 262 for pushing out the buckle 261, so that the buckle 261 is embedded in the slot 302 of the lighting module 300 and keeps the buckle 261 in the position of being locked in the slot 302.

[0086] like Figure 8 As shown, in some embodiments of the present invention, the buckle 261 includes an operating portion 2611 , so that the buckle 261 can be moved out of the slot 302 by operating the operating portion 2611 .

[0087] Those skilled in the art will appreciate that when the user needs to remove the lighting module 300 from the solar module 200, the user can pull the operating portion 2611 to overcome the elastic force of the locking spring 262, so that the buckle 261 moves out of the slot 302. Then, the lighting module 300 can be removed from the solar module 200.

[0088] from Figure 8 As can be seen in the figure, in some embodiments of the present invention, a bevel (not marked in the figure) is provided at one end of the buckle 261 that is inserted into the slot 302. When the user installs the lighting module 300 into the solar module 200, the top of the lighting module 300 first abuts against the bevel, and then as the lighting module 300 continues to be installed, the cooperation between the lighting module 300 and the bevel forces the buckle 261 to retract until the lighting module 300 moves to a position where the buckle 261 is embedded in the slot 302.

[0089] Correspondingly, those skilled in the art may also provide a chamfer or a slope at the top of the lighting module 300 corresponding to the buckle 261 as needed.

[0090] like Figures 6 to 8As shown, in some embodiments of the present invention, the solar module 200 may also be provided with an elastic ejection structure 271 in the accommodating cavity 202 to eject the lighting module 300 out of the accommodating cavity 202 when the buckle 261 moves out of the slot 302 .

[0091] from Figure 8 As can be seen from the figure, the elastic ejection structure 271 can also be retracted. In addition, the solar module 200 further includes an ejection spring 272 for ejecting the elastic ejection structure 271.

[0092] When the lighting module 300 is installed in the receiving cavity 202 of the solar module 200, the lighting module 300 presses the elastic ejection structure 271 and overcomes the elastic force of the ejection spring 272, so that the elastic ejection structure 271 retracts (such as Fig.11 and Fig.12 shown).

[0093] When the lighting module 300 is removed from the solar module 200 , the elastic ejection structure 271 ejects the side of the lighting module 300 having the slot 302 under the action of the ejection spring 272 , thereby facilitating the user to hold the lighting module 300 .

[0094] like Figures 6 to 8 As shown, in some embodiments of the present invention, the solar module 200 is provided with power supply terminals 280 located on the top side of the accommodating cavity 202 , and the specific number of the power supply terminals 280 may be two, three, four, five, etc.

[0095] like Fig.10 As shown, in some embodiments of the present invention, a power receiving terminal 303 is provided on the top side of the lighting module 300 for supplying power to the solar module 200. The power receiving terminal 303 is adapted to the power supply terminal 280.

[0096] like Fig.11 and Fig.13 As shown, in the assembled state, the power receiving terminal 303 is electrically connected to the power supply terminal 280 , so that the solar module 200 supplies power to the lighting module 300 .

[0097] like Figure 6 to Figure 7 As shown, in some embodiments of the present invention, the solar module 200 is provided with a terminal cavity 203 on the top side of the accommodating cavity 202 , and the power supply terminal 280 is disposed in the terminal cavity 203 .

[0098] like Fig.10 As shown, in some embodiments of the present invention, a plug 304 and a sealing ring 305 sleeved on the outer periphery of the plug 304 are arranged on the top of the lighting module 300, and the power receiving terminal 303 is arranged on the plug 304. That is, the plug 304 is arranged on the side of the top shell 310 away from the bottom shell 320.

[0099] Furthermore, the size of the plug 304 is smaller than that of the terminal cavity 203 to ensure that the plug 304 can be inserted into or removed from the terminal cavity 203 as the lighting module 300 rotates. The sealing ring 305 is interference-fitted with the terminal cavity 203 to seal the terminal cavity 203 .

[0100] In order to ensure the reliability of the contact between the power supply terminal 280 and the power receiving terminal 303, the power supply terminal 280 is set to a telescopic elastic structure, and the area of ​​the surface where the power receiving terminal 303 contacts the power supply terminal 280 is larger than the area of ​​the surface where the power supply terminal 280 contacts the power receiving terminal 303 (such as Fig.13 shown).

[0101] In addition, those skilled in the art may also configure the power receiving terminal 303 to be a telescopic elastic structure as required.

[0102] Since the telescopic elastic structure is a conventional structure and is well known to those skilled in the art, in order to facilitate those skilled in the art to understand the technical solution of the present invention, the following reference is made to Fig.14 The power supply terminal 280 of the present invention will be briefly described.

[0103] like Fig.14 As shown, the power supply terminal 280 includes a fixed section 281, a telescopic section 282 and a telescopic spring 283, wherein the fixed end is fixedly connected to the top wall of the terminal cavity 203 and has a cavity for accommodating the telescopic section 282. The telescopic section 282 can be telescopically inserted into the cavity in the fixed section 281. The telescopic spring 283 is arranged in the inner cavity and is located between the fixed section 281 and the telescopic section 282 to provide the telescopic section 282 with a force to extend out of the fixed section 281.

[0104] The following is a brief description of the installation and disassembly processes of the solar lamp 001 in some embodiments of the present invention.

[0105] Assembly process:

[0106] First, insert the insertion protrusion 301 of the lighting module 300 into the slot 2021 of the solar module 200, and then push the end of the lighting module 300 away from the insertion into the accommodating cavity 202 of the solar module 200 until the buckle 261 of the solar module 200 is embedded in the slot 302 of the lighting module 300. At this point, the lighting module 300 is installed in the solar module 200. During this process, the lighting module 300 will rotate around its insertion protrusion 301.

[0107] Then, the buckle structure 230 of the solar module 200 is aligned with the avoidance notch 102 of the bracket 100 , and the solar module 200 is inserted into the top end of the bracket 100 .

[0108] Finally, the screw 400 is screwed into the threaded hole 103 at the top of the bracket 100 , and the screw 400 is extended into the fixing groove 201 of the solar module 200 .

[0109] Disassembly process:

[0110] First, screw the screw 400 out of the fixing slot 201 of the solar module 200 .

[0111] Then, the user presses the buckle structure 230 with his thumb and pulls the solar module 200 together with the lighting module 300 off the bracket 100 .

[0112] Finally, the operating portion 2611 of the buckle 261 on the solar module 200 is moved to remove the buckle 261 from the slot 302 of the lighting module 300, and thus the elastic ejection structure 271 ejects the end of the lighting module 300 with the slot 302 out of the accommodating cavity 202. At this point, the user can remove the lighting module 300 from the solar module 200. During the process of the elastic ejection structure 271 ejecting the end of the lighting module 300 with the slot 302, the lighting module 300 rotates around its insertion protrusion 301.

[0113] It is understood by those skilled in the art that, since the power supply terminal 280 is a telescopic elastic structure, and the lighting module 300 rotates during the process of being installed on the solar module 200 and during the process of being removed from the solar module 200, there will be relative sliding between the power supply terminal 280 and the power receiving terminal 303, so that the contacting surfaces of the power supply terminal 280 and the power receiving terminal 303 will be worn.

[0114] When an oxide film exists on the contacting surfaces of the power supply terminal 280 and the power receiving terminal 303 , the relative sliding can also remove the oxide film, thereby ensuring the stability of the solar lamp 001 during operation.

[0115] Refer to the following Figures 15 to 17 The relative friction process between the power supply terminal 280 and the power receiving terminal 303 will be briefly described.

[0116] During the installation of the lighting module 300, as the lighting module 300 rotates, the power supply terminal 280 and the power receiving terminal 303 first come into contact (eg, Fig.15 As shown), then slide relative to each other (from Fig.15 Move the displayed position to Fig.16 As a result, the surfaces of the power supply terminal 280 and the power receiving terminal 303 that are in contact with each other are worn, thereby removing the oxide film on the surfaces of the power supply terminal 280 and the power receiving terminal 303 that are in contact with each other.

[0117] During the disassembly of the lighting module 300, as the lighting module 300 rotates, the power supply terminal 280 and the power receiving terminal 303 first slide relative to each other (from Fig.16 Move the displayed position to Fig.15 As shown in the figure), they are then separated from each other, so that the surfaces where the power supply terminal 280 and the power receiving terminal 303 contact each other are worn again.

[0118] like Fig.17 As shown, during the installation and removal of the lighting module 300, the power receiving terminal 303 is affected by the power supply terminal 280, and the surface in contact with the power supply terminal 280 forms a friction area 3031. The length of the friction area 3031 is the sliding stroke of the power supply terminal 280 relative to the power receiving terminal 303.

[0119] Fig.17 The dotted line portion with a center mark of the friction area 3031 shown in FIG. 1 is the position of the power supply terminal 280 on the power receiving terminal 303 when the lighting module 300 and the solar module 200 are assembled.

[0120] Based on the above description, it can be understood by those skilled in the art that the present invention enables the lighting module 300 to be installed on the solar module 200 in a rotating manner, and sets one of the power supply terminal 280 and the power receiving terminal 303 as a telescopic elastic structure, so that the power supply terminal 280 and the power receiving terminal 303 first abut and then slide relative to each other during the rotation of the lighting module 300, so that the contact surface of the power supply terminal 280 and the power receiving terminal 303 is worn, and the oxide film can be removed. Therefore, the solar lamp 001 of the present invention can effectively remove the formed oxide film at least during the installation of the lighting module 300, ensuring the stability of the solar lamp 001 during operation.

[0121] So far, the technical solution of the present invention has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the present invention is not limited to these specific embodiments. Without departing from the technical principles of the present invention, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present invention will fall within the protection scope of the present invention.
