Description

Technical Field

[0001] The present application relates to the field of photovoltaic lighting technology, and in particular to a solar lamp with a power supply mounting bracket. Background Art

[0002] As the global demand for renewable energy continues to increase, solar energy, as a clean and renewable energy source, has attracted widespread attention.

[0003] Solar lights are lamps that convert solar panels into electrical energy. During the day, even on cloudy days, this solar generator can collect and store solar energy. As a safe and environmentally friendly new electric light, solar lights are becoming more and more popular. The working principle of solar lights is simple. Solar panels are made using the principle of photovoltaic effect. During the day, solar panels receive solar radiation and convert it into electrical energy output. After the charge and discharge controller detects that the voltage is lower than the set value, it will start to operate, and the battery will discharge to the lamp body to start lighting.

[0004] In the related solar lamps, the lamp body is integrated with the battery, and the solar panel and the battery are connected together through cables, or even the solar panel and the lamp body are integrated together to convert the collected solar energy into electrical energy and store it in the battery to power the lamp body in a dim light environment.

[0005] However, since solar lamps are usually installed in environments with sufficient light, the lamp body tends to get hot due to long-term exposure to light during the day. The lamp housing is in a high-temperature environment where air is difficult to circulate, resulting in a high operating temperature of the battery in the lamp housing, which seriously affects the battery life. Once the battery or the lamp body is damaged, both or even both of them together with the solar panel need to be replaced, resulting in a high maintenance cost for the lamp. Utility Model Content

[0006] In view of the deficiencies in the prior art, the present application provides a solar lamp with a power supply mounting bracket, which can reduce the operating temperature of the battery, ensure the battery life, and reduce the maintenance cost of the lamp.

[0007] In order to achieve the above-mentioned purpose, this application adopts the following technical solutions:

[0018] As one embodiment, the mounting frame includes two second mounting beams, each of the first mounting beams is connected to one second mounting beam at both ends, and the two second mounting beams are detachably connected to the back sides of two opposite frame edges of the frame body.

[0019] As one embodiment, the mounting frame includes a cylindrical portion connected to the back side of the at least two first mounting beams, the cylindrical portion extends away from the solar panel, and the mounting portion is formed on the cylindrical portion.

[0020] As one implementation manner, the two first mounting beams each include a bottom surface and a side surface that are perpendicular to each other, and the two ends of the power supply assembly are respectively fixed to the bottom surfaces of the two first mounting beams and the end surfaces are opposite to the side surfaces of the two first mounting beams.

[0025] The power supply component of the solar lamp of the present application is installed on the mounting frame on the back of the solar panel and is located on the side of the mounting frame facing away from the solar panel. During use, the power supply component is hidden on the back of the solar panel to avoid direct sunlight and does not come into contact with the high-temperature solar panel.

[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0037] 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.

[0038] See also Figures 1-2 The embodiment of the present application provides a solar lamp with a power supply mounting bracket, including a lamp body (not shown), a solar panel assembly 10 and a power supply assembly 20. The lamp body is provided with a light source. The solar panel assembly 10 includes a solar panel 11 and a mounting bracket 13 detachably provided on the back of the solar panel 11. The solar panel 11 is electrically connected to the lamp body. The mounting bracket 13 includes a mounting portion for mounting the solar lamp on an installation object.

[0039] The power supply assembly 20 is electrically connected to the solar panel 11, and is used to store the electric energy generated by the solar panel 11, and provide it to the lamp body for lighting according to the situation. The power supply assembly 20 is arranged on the side of the mounting frame 13 facing away from the solar panel 11, and is spaced apart from the solar panel 11 and completely shielded by the solar panel 11.

[0040] Furthermore, since the power assembly 20 is separated from the solar panel 11 , the high temperature generated by the operation and exposure of the solar panel 11 is difficult to be transmitted to the power assembly 20 , thereby ensuring that the power assembly 20 operates at a relatively low temperature.

[0041] When the solar lamp is installed on the installation object, it is only necessary to fix the mounting frame 13 to the installation object through the mounting part. The solar panel 11 is located above the mounting frame 13 and faces the sun to absorb as much light as possible; the power supply component 20 is fixed to the side of the mounting frame 13 facing away from the solar panel 11, so as to maintain a certain distance from the solar panel 11 and be shielded by the solar panel 11. In this way, direct light can be prevented from shining on the power supply component 20, and the high temperature generated by the solar panel 11 exposed to the sun can be prevented from being transmitted to the power supply component 20.

[0042] Exemplarily, the mounting frame 13 and the power supply assembly 20 are both exposed to the air, and there is no need to use a protective shell to wrap the mounting frame 13 or the power supply assembly 20. The protective shell will not wrap the solar panel 11 in a closed space, which will affect the heat dissipation of the power supply assembly 20. The heat generated by the power supply assembly 20 can be directly dissipated into the air. The power supply assembly 20 will not be in a high temperature environment because the closed protective shell absorbs the heat conducted by the solar panel 11 or the protective shell generates high temperature after being exposed to the sun.

[0043] Combination Figure 3 As shown, the power supply assembly 20 may include an electrical box 21 and a circuit board 22 and a battery 23 disposed in the electrical box 21. The circuit board 22 and the battery 23 are electrically connected, and the surface of the electrical box 21 is attached to the side of the mounting frame 13 facing away from the solar panel 11. The circuit board 22 may be integrated with a charging circuit and a charging management chip, and the battery 23 may store the electric energy converted by the solar panel 11.

[0044] Since the power supply assembly 20 is disposed on the solar panel assembly 10, there is no need to set a power supply on the lamp body, the weight of the lamp body is lighter, the installation is more convenient, and the cost is lower. It is understandable that in some embodiments, a backup power supply can also be set on the lamp body, and the power supply assembly 20 and the backup power supply are combined to supply power to the lamp body. In addition, a circuit board can also be set on the lamp body.

[0045] In one embodiment, the solar panel assembly 10 further includes a frame 12, which surrounds the solar panel 11 on all sides, thereby protecting the solar panel 11 and preventing the solar panel 11 from being damaged by accidental collisions. Exemplarily, the frame 12 is a rectangular frame structure, and the longitudinal sections of the frames on its four sides may be U-shaped or L-shaped, wrapping the surroundings and surface edges of the solar panel 11. For example, when the longitudinal section of the frame of the frame 12 is U-shaped, the periphery and upper and lower surfaces of the solar panel 11 are all wrapped by the frame, and when the longitudinal section of the frame of the frame 12 is L-shaped, the periphery and upper or lower surfaces of the solar panel 11 are wrapped by the frame.

[0046] Specifically, the mounting frame 13 is installed on the back of the frame 12 and forms a gap with the solar panel 11. Figure 4 As shown, in one embodiment, the thickness of the frame 12 is greater than the thickness of the solar panel 11, and the solar panel 11 is fixed in the frame 12 and is spaced apart from the bottom surface of the frame 12, so that the back of the solar panel 11 is spaced apart from the mounting frame 13. In this way, the solar panel 11 and the mounting frame 13 are not in direct contact and are far away from each other. The heat generated by the solar panel 11 after being exposed to the sun is rarely transmitted to the mounting frame 13, and is also difficult to be transmitted to the power supply assembly 20. Therefore, the life of the power supply assembly 20 can be guaranteed.

[0047] Combination Figures 1 to 3 As shown, the mounting frame 13 includes at least two first mounting beams 131, and the at least two first mounting beams 131 are fixed on the back of the solar panel assembly 10 at intervals along the length direction of the solar panel 11, and the power supply assembly 20 is simultaneously installed on the surface of the at least two first mounting beams 131 facing away from the solar panel 11.

[0048] Due to the gap between the two first mounting beams 131 , the gap can be used as a heat dissipation gap for the power supply assembly 20 , thereby preventing the power supply assembly 20 from being completely attached to the first mounting beams 131 and causing poor heat dissipation.

[0049] In one embodiment, the mounting frame 13 further includes two second mounting beams 132 , each first mounting beam 131 is connected to a second mounting beam 132 at both ends, and the two second mounting beams 132 are detachably connected to the back sides of two opposite frame edges of the frame body 12 .

[0050] By connecting each first mounting beam 131 side by side between two second mounting beams 132, and detachably fixing the second mounting beam 132 to two opposite frame edges of the frame 12, each first mounting beam 131 can be suspended and installed on the back of the solar panel assembly 10, and the power supply assembly 20 can be suspended and installed on the back of the two first mounting beams 131. In this way, the power supply assembly 20 has as much area as possible exposed to the air, has good ventilation and heat dissipation effects, and can also avoid the transfer of heat on the mounting frame 13. Exemplarily, the two second mounting beams 132 are respectively attached to the two opposite frame edges in the width direction of the frame 12, and the first mounting beam 131 extends along the length direction of the frame 12. Among them, the two second mounting beams 132 and the two first mounting beams 131 can be set in one piece.

[0051] like Figure 3 In the illustrated embodiment, the mounting frame 13 includes a barrel portion 133 connected to the back of at least two first mounting beams 131, the barrel portion 133 extends away from the solar panel 11, and the mounting portion is formed on the barrel portion 133. The barrel portion 133 can be connected to the lamp pole M, so that the solar panel 11 is fixedly installed at a higher height. For example, the barrel portion 133 can be used for the lamp pole M to pass through. Specifically, the side wall of the barrel portion 133 is provided with a plurality of screw holes arranged at intervals in the circumferential direction, and the lamp pole can be inserted into the barrel portion 133, and the lamp pole can be fixed in the barrel portion 133 by passing the screws T1 through each screw hole. It can be understood that in other embodiments, the lamp pole M can also be sleeved outside the barrel portion 133.

[0052] The first mounting beam 131 , the frame edge of the frame 12 , and the second mounting beam 132 may all be formed by a hollow tube, which saves cost and reduces product weight compared to a solid plate, and is also beneficial to product heat dissipation.

[0053] like Figure 5 and Figure 6 As shown, in some embodiments, the two first mounting beams 131 can be L-shaped, and the first mounting beams 131 include a bottom surface and a side surface that are perpendicular to each other. The two ends of the power supply component 20 are respectively fixed on the bottom surfaces of the two first mounting beams 131 and the end surfaces are opposite to the side surfaces of the two first mounting beams 131.

[0054] The first mounting beam 131 is an L-beam, and two L-beams are arranged adjacent to each other. The two ends of the power supply assembly 20 are respectively fixed to the bottom surface of each L-beam and the end surface is opposite to the side surface of each L-beam. The L-beam can protect the power supply assembly 20 therein. In other embodiments, the first mounting beam 131 can also be T-shaped. Compared with a planar beam structure, by setting the first mounting beam 131 as an L-beam or a T-shaped beam, the structure of the first mounting beam 131 is more economical, and the two ends of the power supply assembly 20 can also be protected therein.

[0055] Figure 5 and Figure 6 In, different from Figures 1 to 3 The embodiment shown uses a lamp pole M as a mounting object to mount the solar panel 11. By replacing the mounting frame 13 with another structure, the solar panel 11 of this embodiment can be mounted on a vertical mounting object such as a wall.

[0056] Specifically, the mounting frame 13 is a plurality of triangular beams arranged at intervals, and the mounting frame 13 includes at least two third mounting beams 134 and at least two fourth mounting beams 135. One end of the third mounting beam 134 is connected to a corresponding first mounting beam 131, and the other end extends away from the solar panel 11. Each fourth mounting beam 135 is respectively connected to a third mounting beam 134 and a first mounting beam 131 to form a triangular beam. Two or more triangular beams are arranged at intervals on the back of the solar panel assembly 10, and the mounting portion is formed on the third mounting beam 134. Exemplarily, the third mounting beam 134 is provided with a through mounting hole 1340, and the mounting hole 1340 is used as the mounting portion. By passing a screw through the mounting hole 1340, the third mounting beam 134 can be fixed to the wall or other mounting facade, and the triangular beam serves as a supporting structure to suspend the solar panel 11. By adjusting the inclination angle between the third mounting beam 134 and the first mounting beam 131, the angle of the solar panel 11 can be adjusted.

[0057] like Figure 3 The back of the frame 12 may be provided with a plurality of screw holes K1, K2, each of which includes a plurality of screw holes, which may be used to connect to a different mounting bracket 13. For example, Figures 1 to 4 The mounting bracket 13 shown can be mounted in one of the sets of screw holes K1. Figures 5-6 The mounting frame 13 can be installed in another set of screw holes K2. In this way, by combining the solar panel assembly 10 with different mounting frames 13, the solar panel assembly 10 can be adapted to different installation modes to meet different installation requirements.

[0058] To summarize, the power supply assembly of the solar lamp of the present application is installed on the mounting frame on the back of the solar panel, and is located on the side of the mounting frame facing away from the solar panel. During use, the power supply assembly is hidden on the back of the solar panel to avoid direct light and does not come into contact with the high-temperature solar panel. This can not only prevent the battery from working at a high temperature for a long time and affecting its lifespan, but also prevent the battery from being set in the shell of the lamp body. When the lamp body or battery needs to be maintained or replaced, only the damaged structure needs to be replaced separately, without the need to replace the lamp body or solar panel as a whole, thereby reducing the maintenance cost of the lamp.

[0059] 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.
