In the following, for the convenience of understanding each embodiment, after the solar lamp is actually installed, the surface located on the upper side is called the "top surface", and the surface located on the lower side is called the "bottom surface".

[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] Figure 1 , 2 The schematic diagrams respectively show the structure of the solar lamp in a folded state at different viewing angles according to an embodiment of the present application; Figure 3 , 4 The schematic diagrams respectively show the structure of the solar lamp in an unfolded state from different perspectives according to an embodiment of the present application.

[0043] like Figures 1 to 4 An embodiment of the present application provides an angle-adjustable solar lamp, comprising:

[0044] The lamp body 10 has a light emitting surface, and includes a light source component and a power supply component that are electrically connected;

[0045] The lamp cover 20 is rotatably connected to the lamp body 10 and has a folded state and at least one unfolded state; an end of the lamp cover 20 away from its rotation axis is provided with a mounting portion to mount the lamp cover 20 on a mounting object, and the mounting object may vary according to actual conditions, for example, it may be a column, a lamp pole, a wall or other facade, etc.;

[0046] The solar panel 30 is electrically connected to the lamp body 10 and can convert solar energy into electrical energy, thereby supplying power to the lamp body 10;

[0047] In the unfolded state, the lamp cover 20 is positioned at an angle relative to the lamp body 10 ; in the folded state, the lamp cover 20 covers the surface of the lamp body 10 that is opposite to the light emitting surface.

[0048] The lamp body 10 and the lamp cover 20 of the solar lamp of the present application can rotate relative to each other, and can be folded or unfolded as needed during the rotation process. By setting the mounting part of the lamp on the lamp cover, the emission direction of the light source in the lamp body 10 can be adjusted after the lamp is installed, and the volume of the lamp can be reduced during transportation or storage, making the shape of the lamp novel and beautiful, and enriching the application scenarios of the lamp.

[0049] In this embodiment, the solar panel 30 is laid on the top surface of the lamp cover 20, for example, it is clamped on the lamp cover 20 by means of a snap or the like, or it is fixed to the lamp cover 20 by means of welding, clamping, etc. Therefore, the solar panel 30 can change the angle between itself and the lamp body 10 as the lamp cover 20 rotates, thereby changing the orientation relationship between the lamp body 10 and the solar panel 30.

[0050] Since the solar panel 30 and the lamp body 10 of the lamp are respectively installed on different parts of the lamp, they can be adjusted to face different directions. The solar panel can face upward to receive solar energy, and the light-emitting surface of the lamp body can face various required irradiation directions, thereby avoiding the phenomenon that the orientation of the solar panel 30 and the irradiation direction of the lamp body 10 are always opposite to each other in actual usage scenarios. Therefore, after the lamp of this embodiment is installed, the angle of the emitting surface of the lamp body 10 relative to the solar panel 30 can be changed as needed, which can take into account both the light utilization rate of the solar panel and the irradiation range of the lamp, so that the solar lamp has more application scenarios and a wider application range.

[0051] In one embodiment, the mounting portion includes a hook portion 21 disposed on the end surface of the lamp cover 20 away from its rotation axis. By providing the hook portion 21, the lamp can be fixed to the installation object by passing screws, pins, etc. on the installation object through the hook portion 21.

[0052] Exemplarily, the hooking portion 21 includes a first notch 211 penetrating the bottom surface of the lamp cover 20 and a blocking edge 212 arranged at the edge of the first notch 211, and the blocking edge 212 surrounds the first notch 211 to prevent the screw from coming out. When the hooking portion 21 is hooked on the screw, the screw cap is located in the first notch 211, and the blocking edge 212 is engaged with the screw cap of the screw. The first notch 211 allows the screw rod of the screw to pass through, and the blocking edge 212 limits the screw cap of the screw in the first notch 211. It can be understood that there can be multiple hooking portions 21, and the multiple hooking portions 21 are arranged at intervals along the length direction of the lamp cover 20 so as to be respectively engaged with multiple screws or pins to improve the stability of the lamp installation.

[0053] Further, the mounting portion may include a first recessed portion 22 and two hooking portions 21 spaced apart along the length direction of the lamp cover 20, wherein the first recessed portion 22 is recessed between the two hooking portions 21. The first recessed portion 22 may fit with the mounting object, for example, when the column is circular or elliptical, the first recessed portion 22 may be recessed in an arc shape, so that the first recessed portion 22 may fit with the column. It is understood that in other embodiments, the first recessed portion 22 may also be a shape that matches the surface shape of the mounting object, such as a square.

[0054] In one embodiment, in combination Figure 2 and Fig.10The lamp cover 20 includes a first channel 23 connected to the first notch 211 and passing through the top surface of the lamp cover 20. A binding structure such as a cable tie or a rope can be passed through the corresponding first notch 211 and the first channel 23 and then fastened to the installation object, thereby cooperating with the first recessed portion 22 and the column-like installation object to install the lamp on the surface of the installation object. Alternatively, the lamp cover 20 may also include a second channel 24 connected to the two hooking portions 21. A binding structure such as a cable tie or a rope can be passed through the two first notches 211 and the second channel 24 at the same time, and the lamp can be installed on the surface of the installation object in cooperation with the first recessed portion 22. It is understandable that in some installation and fixing methods, the first recessed portion 22 may also be omitted.

[0055] In the above embodiment, the hook portion 21 can be used in conjunction with screws to hook the lamp on the surface of an installation object such as a wall, and can also be used as a threading hole to cooperate with binding structures such as cable ties to bind and fix the lamp to an installation object such as a column, thus achieving multiple uses.

[0056] In one embodiment, the lamp cover 20 may further include an extension portion 200 extending from an end away from the rotation axis toward the top surface thereof, and the mounting portion is disposed on the extension portion 200; in the folded state, the extension portion 200 surrounds the side of the lamp body 10. From the outside, the extension portion 200 can block or partially fold the side of the lamp body 10, which can achieve an aesthetic effect and protect the lamp body 10. The lamp cover 20 can also be fastened to the lamp body 10 by providing a buckle or other structure on the extension portion 200 to cooperate with the lamp body 10, so as to prevent the lamp from being easily opened after being folded. For example, after the lamp cover 20 covers the lamp body 10, it can completely block the top surface of the lamp body 10. From the outside, the lamp is folded into a box, which reduces the volume occupied by the lamp.

[0057] In addition, a button K for controlling the lamp body 10 may be provided on the side of the lamp body 10 facing away from the light emitting surface. For example, the button K may be a button for controlling the power on and off of the lamp body 10, or a button for controlling the working mode of the lamp body 10 (such as brightness, color temperature, working logic, etc.).

[0058] Further integration Figure 5 and Figure 6 As shown, in some embodiments, the lamp cover 20 and the lamp body 10 are damped to position the lamp cover 20 in multiple unfolded states. That is, there is a large friction between the lamp cover 20 and the lamp body 10, so that the angle between the lamp cover 20 and the lamp body 10 can be infinitely adjusted. It only takes a rotational force to be applied to the lamp cover 20 or the lamp body 10, and the angle between the lamp cover 20 and the lamp body 10 remains unchanged after the external force is removed. For example, this function can be achieved by providing a gear mating surface between the lamp cover 20 and the lamp body 10, or by providing a damping gasket.

[0059] In this embodiment, the lamp cover 20 includes a first rotating part 201 and a limiting part 202 arranged on the periphery of the first rotating part 201, and the lamp body 10 includes a second rotating part 101, an arc groove 102 coaxially arranged with the second rotating part 101, and a stop part 103 arranged at one end of the arc groove 102 facing away from the lamp cover 20; the first rotating part 201 is rotatably connected to the second rotating part 101, and the limiting part 202 can slide along the arc groove 102 and be blocked by the stop part 103 to limit the maximum unfolding angle of the lamp cover 20.

[0060] The limiting portion 202 may be an arc-shaped extension portion arranged concentrically with the first rotating portion 201, or may be a convex column axially extending from the first rotating portion 201. When the lamp cover 20 rotates relative to the lamp body 10 around the rotating axis, the limiting portion 202 may slide along the arc-shaped groove 102. When the limiting portion 202 slides to the end of the arc-shaped groove 102, the limiting portion 202 abuts against the stopper 103 and is restricted from further rotation. At this time, the lamp cover 20 is at the maximum unfolding angle.

[0061] In one embodiment, the lamp body 10 may specifically include a lamp housing component with a receiving space formed therein, and at least one of the light source component and the power supply component is disposed in the lamp housing component. For example, the light source component and the power supply component may both be disposed in the lamp housing component.

[0062] In one embodiment, the lamp housing assembly includes an upper shell 11, a middle shell 12 and a lower shell 13, wherein the space enclosed by the upper shell 11 and the middle shell 12 accommodates the power supply assembly therein, the middle shell 12 has a plurality of light-transmitting windows, and the lower shell 13 is a lower cover plate, which is arranged on the surface of the middle shell 12 facing away from the upper shell 11 to protect the light-transmitting windows of the middle shell 12 therein, and the portion of the lower shell 13 corresponding to the light-transmitting windows is made of light-transmitting material, and the light emitted by the light source assembly can be emitted out of the lamp body 10 through the corresponding light-transmitting windows.

[0063] For example, Figure 5 The light source assembly of this embodiment includes a first light source group 14 and a second light source group 15 arranged on at least one side of the first light source group 14 along the length direction of the lamp body 10, and the light emitting direction of the second light source group 15 is inclined toward the outside of the angle-adjustable solar lamp relative to the light emitting direction of the first light source group 14. Each of the first light source group 14 and the second light source group 15 may include a plurality of point light sources arranged in an array.

[0064] The arrangement area of ​​the first light source group 14 is larger than the arrangement area of ​​the second light source group 15, so that the first light source group 14 is the main light source, the second light source group 15 is the auxiliary light source, and the first light source group 14 has a larger radiation range. By arranging the second light source group 15 tilted outward next to the second light source group 15, the first light source group 14 can irradiate directly below the lamp, and the second light source group 15 can radiate around the lamp, thereby improving the irradiation range of the lamp. Exemplarily, the two groups of second light source groups 15 are respectively arranged on both sides of the length direction of the first light source group 14, so that the radiation range on both sides of the first light source group 14 is improved. Furthermore, each group of the second light source group 15 is respectively provided with two array areas, and the second light source groups 15 in the two array areas are respectively arranged side by side in the width direction of the lamp body 10.

[0065] In one embodiment, the first light source group 14 is installed on a first installation surface, and the second light source group 15 is installed on a second installation surface. The two second installation surfaces are arranged obliquely relative to the first installation surface.

[0066] In one embodiment, the solar lamp may further include at least one sensor head 16, which is a proximity sensor that can sense whether a person is approaching and send a signal to turn on the lamp when a person is approaching. For example, the sensor head 16 may be an infrared sensor. Each sensor head 16 is arranged side by side with the corresponding second light source group 15 on one side of the first light source group 14. For example, a sensor head 16 may be arranged on both sides of the length direction of the first light source group 14 to achieve a wider range of proximity detection and higher detection sensitivity. Furthermore, a sensor head 16 may be arranged between the two second light source groups 15 on each side of the first light source group 14.

[0067] Exemplarily, the light emitting directions of the sensor head 16 and the second light source group 15 are consistent, or the sensor head 16 and the second light source group 15 are installed on the same installation surface or are installed on installation surfaces parallel to each other.

[0068] like Figures 7 to 10 , shows a solar lamp according to an embodiment of the present application, which is different from the above embodiments in that the solar panel 30 is separately arranged from the lamp cover 20 and the lamp body 10, and is connected to the lamp body 10 via a cable. That is, the solar panel 30 is no longer arranged on the lamp cover 20, and the solar panel 30 can be installed at any position using a separate mounting bracket 31, so that the installation angle of the solar panel 30 and the installation angle of the lamp body 10 do not affect each other.

[0069] In addition, the mounting portion may include two threading holes 25 spaced apart along the length direction of the lamp cover 20. In addition to the threading holes 25, the mounting portion may also include a hooking portion 21, which has the same structure as the above-mentioned hooking portion 21, and will not be described in detail here. Fig. 9The figure shows a situation where two threading holes 25 are located between two hooking parts 21 and the first recessed part 22 is located between the two threading holes 25. The lamp cover 20 includes a third channel 26 that is connected to the threading holes 25 and passes through the top surface of the lamp cover 20. A binding structure such as a cable tie or a rope can be passed through the corresponding threading holes 25 and the third channel 26 and then fastened to the installation object, thereby cooperating with the first recessed part 22 and the installation object such as a column to install the lamp on the surface of the installation object. Alternatively, the lamp cover 20 can include a second channel 24 that is connected to the two threading holes 25. A binding structure such as a cable tie or a rope can be passed through the two threading holes 25 and the second channel 24 at the same time to cooperate with the first recessed part 22 to install the lamp on the surface of the installation object.

[0070] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
