Description

A solar-powered floodlight Technical Field

[0001] This utility model relates to the field of energy-saving lighting technology, specifically a solar-powered floodlight wall lamp. Background Technology

[0002] Floodlights are commonly used outdoor lighting fixtures, primarily in places such as mines, stadiums, bridges, and parks. Floodlights are typically deployed in large numbers to create lighting effects from different locations. However, the more floodlights used, the more electricity is consumed, placing a greater burden on the power system. Furthermore, each floodlight needs its own wiring, and the more floodlights used, the more cables are laid, creating a complex wiring environment that can easily lead to safety hazards and cause inconvenience in the long run.

[0003] To address the above shortcomings, we need to develop a solar-powered floodlight to meet the needs of a wide range of users. Summary of the Invention

[0004] In view of the aforementioned issues that existing floodlights place a heavy burden on the power system when used in large quantities, and that extensive wiring can easily cause safety hazards, the technical solution adopted by this utility model to solve these problems is as follows:

[0005] A solar-powered floodlight includes a light source and a lamp housing for mounting the light source. The lamp housing has a hinged portion with a lamp bracket for stable support and a solar module for auxiliary power supply. The solar module is electrically connected to the lamp housing and includes a battery for storing electrical energy.

[0006] The lamp body bracket and the solar module are respectively flipped open relative to the lamp body shell with the shell hinge as the center to form an unfolded posture, or the lamp body bracket and the solar module are brought close together and attached to the lamp body shell to form a closed posture.

[0007] As described above, in a solar-powered floodlight wall lamp, the lamp body bracket is installed between the lamp body shell and the solar module. The lamp body bracket has a hollow accommodating space d to allow the lamp body shell to pass through. The cable of the solar module passes through the accommodating space d and the lamp body shell and is connected to the light source.

[0008] As described above, a solar-powered wall lamp has a lamp body bracket with a first support arm, a second support arm, and a third support arm arranged sequentially at both ends. The first support arm and the third support arm are respectively installed at the first hinge end m and the second hinge end n of the housing hinge portion. The first support arm, the second support arm, and the third support arm surround the surface of the lamp body housing to form the accommodating space d.

[0009] As described above, in a solar-powered wall lamp, the second support arm has a through bracket mounting portion that facilitates stable installation. The bracket mounting portion adopts a round hole structure and / or a slot structure.

[0010] As described above, in a solar-powered wall lamp, the first support arm is perpendicular to the second support arm, and the connection point between the first support arm and the second support arm adopts a rounded corner structure.

[0011] The second support arm is perpendicular to the third support arm, and the connection between the second support arm and the third support arm adopts a rounded corner structure.

[0012] As described above, a solar-powered wall lamp includes a structural surface a on the side emitting light and a structural surface b on the side away from the structural surface a, and the hinge portion of the housing is located on the lateral surface c between the structural surface a and the structural surface b.

[0013] The solar module includes a structural surface e for absorbing sunlight and a structural surface f located on the side away from the structural surface e. A solar panel is installed on the structural surface e, and a module hinge portion extends from the structural surface f for connecting the housing hinge portion.

[0014] The lamp body bracket has a bracket hinge portion for connecting the housing hinge portion.

[0015] As described above, in a solar-powered wall lamp, the module hinge and the bracket hinge pass through and are coaxially mounted on the housing hinge. In the unfolded position, the structural surface a forms an angle g with the lamp body bracket, and the structural surface e forms an angle h with the lamp body bracket. The total angle of the angle g and the angle h is greater than 90 degrees.

[0016] As described above, a solar-powered floodlight wall lamp includes a light-emitting panel composed of LED beads or LED sheets, a light-expanding inner cover extending outward from the light-emitting panel, and a current-regulating and voltage-regulating module for input to the solar module. The light-emitting panel illuminates from the narrow end of the light-expanding inner cover toward the expanding end of the light-expanding inner cover. The expanding end is located near the structural surface a, and the structural surface b has heat dissipation ribs for heat dissipation during lighting.

[0017] As described above, in a solar-powered floodlight wall lamp, a first transparent element is installed on structural surface a for illumination transmission and light source protection, and a second transparent element is installed on structural surface e for light absorption transmission and module protection.

[0018] As described above, in a solar-powered wall lamp, the hinge has an arm for hinged connection, which passes through the bracket hinge, the housing hinge, and the module hinge, respectively, so that the lamp body bracket, the lamp body housing, and the solar module can rotate coaxially. The hinge has an anti-slip structure near the outer side for easy screwing.

[0019] The beneficial effects of this utility model are as follows:

[0020] This invention improves upon traditional floodlights by installing a lamp body bracket to stabilize the placement angle of the floodlight, ensuring a stable angle and posture of illumination. The bracket also allows for wall-mounting, adapting to various lighting locations. Before use, simply unfold and lay it at the desired location; after use, fold it up for storage and transport. Operation is simple, convenient, and quick. Furthermore, the lamp body housing is equipped with a solar module for environmentally friendly solar power. During the day, solar energy is converted into electricity and stored in a battery. At night, the battery powers the light source. This structure requires no external power system. When deployed in large numbers, it can provide continuous lighting through its own batteries, reducing the burden on the local power system and minimizing power consumption for lighting, thus achieving energy conservation and environmental protection. Since this structure eliminates the need for an external power system, the cabling on-site is limited to the light source and solar module of each floodlight, avoiding complex wiring and effectively reducing safety hazards.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1:

[0029] As shown in Figures 1 to 6, a solar-powered floodlight includes a light source 1 and a lamp body shell 2 for mounting the light source 1. The lamp body shell 2 has a hinged joint 21 with a lamp body bracket 3 for stable support and a solar module 4 for auxiliary power supply. The solar module 4 is electrically connected to the lamp body shell 2 and includes a battery for storing electricity.

[0030] The lamp body bracket 3 and the solar module 4 are respectively flipped open relative to the lamp body shell 2 with the shell hinge part 21 as the center to form an unfolded posture, or the lamp body bracket 3 and the solar module 4 are close together and attached to the lamp body shell 2 to form a closed posture.

[0031] Specifically, in this embodiment, the light source 1 is a light-emitting unit for illuminating light. The light source 1 is installed inside the lamp body housing 2. The front of the lamp body housing 2 is provided with an illumination port for illuminating light. The back of the lamp body housing 2 is provided with a housing hinge 21. The housing hinge 21 is located near the top of the back of the lamp body housing 2. The lamp body bracket 3 and the solar module 4 are installed on the housing hinge 21 so that they can be flipped open or brought closer together relative to the back of the lamp body housing 2. Preferably, the lamp body housing 2, the lamp body bracket 3 and the solar module 4 are flipped coaxially with the hinge position as the center. The lamp body bracket 3 is provided with an installation hole for wall mounting. In this embodiment, the solar module 4 includes a solar panel for absorbing solar energy and converting it into electrical energy, a battery for storing the converted electrical energy, and a DC-DC converter for voltage regulation and transmission.

[0032] Before lighting is used, the lamp body bracket 3 and the solar module 4 are flipped open relative to the lamp body shell 2 with the shell hinge part 21 as the center to form an unfolded posture. Users can place it in the position where they want to emit light. There is no need to connect to the local power system. After adjusting the posture, the lighting can be turned on.

[0033] After use, the lamp body bracket 3 and the solar module 4 are brought together and attached to the lamp body shell 2 with the shell hinge part 21 as the center, forming a closed posture. The user can take them out and store them one by one.

[0034] During the day, the wall lamp can be set up in advance so that it can absorb sunlight through the solar module 4, convert it into electrical energy and store it in the battery. At night, the battery can be used to provide power for the lighting of the light source 1. It can be placed in the site for long-term use.

[0035] This invention improves upon traditional floodlights by installing a lamp body bracket 3 to stabilize the placement angle of the floodlight, ensuring a stable angle and posture of illumination. The bracket 3 also allows for wall-mounting, adapting to various lighting locations. Before use, simply unfold and lay it at the desired lighting location; after use, fold it up for storage and transport. Operation is simple, convenient, and quick. Furthermore, a solar module 4, powered by solar energy, is installed on the lamp body shell 2. During the day, solar energy is converted into electricity and stored in a battery. At night, the battery powers the light source 1. This structure requires no external power system. When deployed in large numbers, it can provide continuous lighting through its own batteries, reducing the burden on the local power system and minimizing power consumption for lighting, thus achieving energy conservation and environmental protection. Since this structure requires no external power system, the cables on-site exist only between the light source 1 and the solar module 4 of each floodlight, avoiding complex wiring environments and effectively reducing safety hazards.

[0036] Furthermore, as another embodiment 101 of embodiment 1, as shown in Figures 1 and 4, the lamp body bracket 3 is installed between the lamp body shell 2 and the solar module 4, so that when the solar module 4 is flipped open, it is not limited by the structure of the lamp body shell 2 or the lamp body bracket 3, and can be freely unfolded on the other side of the lamp body shell 2. The lamp body bracket 3 is located between the lamp body shell 2 and the solar module 4, and can become a stable load-bearing center support position, which is conducive to the stable support of the unfolded structure. The lamp body bracket 3 has a hollow accommodating space d to avoid the lamp body shell 2. The protruding structure on the back of the lamp body bracket 3 can be stored in the accommodating space d, so that the folded structure can reduce the folding thickness and folding volume, which is conducive to storage. The cable of the solar module 4 passes through the accommodating space d and the lamp body shell 2 and is connected to the light source 1, so that the wiring does not occupy external space, and the folded cable can also be stored in the accommodating space d, which is convenient for users to unfold and store.

[0037] Furthermore, as another embodiment 102 of embodiment 1, as shown in FIG6, the lamp body bracket 3 is provided with a first support arm 31, a second support arm 32, and a third support arm 33 at its ends. The first support arm 31, the second support arm 32, and the third support arm 33 are different straight sections on the same elongated structure, and adjacent support arms are transitioned by a corner. The housing hinge portion 21 has two hinge ends for mounting on the left and right sides. The first support arm 31 and the third support arm 33 are respectively mounted on the housing hinge portion 21. The first hinge end 21m and the second hinge end 21n of 1 provide stable support for the left and right sides of the lamp body shell 2. The second support arm 32 reinforces the relative position stability between the first support arm 31 and the third support arm 33. The first support arm 31, the second support arm 32 and the third support arm 33 surround the surface of the lamp body shell 2 to form the accommodating space d. The hollow part of the accommodating space d allows the protruding part on the back of the lamp body shell 2 to extend into it, making it more convenient to close and store the whole thing, reducing storage space, reducing folding thickness and making it convenient for users to store it together.

[0038] Furthermore, as another embodiment 103 of embodiment 102, as shown in FIG6, the second support arm 32 is provided with a through bracket mounting part 34 for easy and stable installation. The bracket mounting part 34 adopts a round hole structure and / or a slot structure.

[0039] Specifically, in this embodiment, the bracket mounting part 34 is a mounting hole opened on the lamp body bracket 3. The bracket mounting part 34 is located on the lamp body bracket 3 away from the housing hinge part 21. It is used to fix the lamp body bracket 3 to the ground or wall of the lighting location, so that the floodlight can meet the required posture or angle for lighting. More specifically, the bracket mounting part 34 can adopt a round hole structure, a slotted hole structure, or both can be used simultaneously and opened separately. As shown in Figure 6, the lamp body bracket 3 of this embodiment has three bracket mounting parts 34. All three bracket mounting parts 34 are opened on the second support arm 32 and are in a through shape. Among them, the bracket mounting part 34 with a round hole structure is located in the middle of the second support arm 32, and the bracket mounting parts 34 with a slotted hole structure are symmetrically opened on the left and right sides with the round hole structure as the center. When in use, the user can use screws and bolts to pass through the bracket mounting part 34 to lock the lamp body bracket 3 to the surface of the ground or wall. If you want to move and adjust, you can lock the screws and bolts in the slotted hole structure. If you want to position accurately, you can lock the screws and bolts in the round hole structure, which is convenient for the user.

[0040] Furthermore, as another embodiment 104 of embodiment 102, as shown in FIG6, the first support arm 31 is perpendicular to the second support arm 32, and the connection and intersection between the first support arm 31 and the second support arm 32 adopts a rounded corner structure; the second support arm 32 is perpendicular to the third support arm 33, and the connection and intersection between the second support arm 32 and the third support arm 33 adopts a rounded corner structure.

[0041] Specifically, in this embodiment, the first support arm 31 is preferably perpendicular to the second support arm 32, and the second support arm 32 is preferably perpendicular to the third support arm 33, so as to adapt to the regular shape of the lamp body shell, provide better support during use, keep the center of gravity in the middle position, and make the placement more stable. The rounded corner structure is adopted at the connection and intersection between the support arms, so that the support arm structure can better distribute the weight force and reduce the impact of sharp right angles on the user.

[0042] Furthermore, as another embodiment 105 of embodiment 1, as shown in FIG1, the lamp housing 2 includes a structural surface a located on the side of illumination and light emission and a structural surface b located on the side away from the structural surface a, and the housing hinge 21 is located on the lateral surface c between the structural surface a and the structural surface b;

[0043] The solar module 4 includes a structural surface e for absorbing sunlight and a structural surface f located on the side away from the structural surface e. A solar panel 41 is installed on the structural surface e, and a module hinge portion 42 extends from the structural surface f for connecting the housing hinge portion 21.

[0044] The lamp body bracket 3 has a bracket hinge portion 35 for connecting the housing hinge portion 21.

[0045] Specifically, in this embodiment, the housing hinge 21 is a hinged extension structure and its hole provided on the lamp body housing 2, the module hinge 42 is a hinged extension structure and its hole provided on the solar module 4, and the bracket hinge 35 is a hinged extension structure and its hole provided on the lamp body bracket 3. The lamp body bracket 3 is located between structural surface b and structural surface f and moves between them. The solar panel 41 is installed on structural surface e and is not affected by the shading of the lamp body housing 2 and the lamp body bracket 3. The light source 1 emits light from structural surface a and is not affected by the shading of the solar module 4 and the lamp body bracket 3. Each of them achieves its own function. The bracket hinge 35 and the module hinge 42 are respectively installed on the housing hinge 21 to achieve coaxial rotation.

[0046] Furthermore, as another embodiment 106 of embodiment 105, as shown in FIG1, the module hinge part 42 and the bracket hinge part 35 pass through the hinge member and are coaxially installed on the housing hinge part 21. In the unfolded posture, the structural surface a forms an angle g with the lamp body bracket 3, and the structural surface e forms an angle h with the lamp body bracket 3. The total angle of the angle g and the angle h is greater than 90 degrees.

[0047] Specifically, in this embodiment, the hinge can be a bolt-shaft structure or a long shaft structure. The shaft arm of the hinge passes through the bracket hinge 35, the housing hinge 21 and the module hinge 42 respectively, so that the three can rotate coaxially. Preferably, the hinge uses friction damping or interference fit to limit the rotation position of the bracket hinge 35, the housing hinge 21 and the module hinge 42. More specifically, the unfolding angle between the structural surface a and the lamp body bracket 3 is angle g, and the unfolding angle between the structural surface e and the lamp body bracket 3 is angle h. The total angle of angle g and angle h is greater than 90 degrees, so that when unfolded, the solar module 4 can absorb solar energy smoothly in a better irradiated posture (unfolded to a horizontal state), and the lamp body bracket 3 can adjust the irradiation angle of more lamp sources 1 and implement stable support at different angles to improve the stability of the structure.

[0048] Furthermore, as another embodiment 107 of embodiment 105, as shown in FIG5, the light source 1 includes a light-emitting panel 11 composed of LED beads or LED sheets, a light-expanding inner cover 12 extending obliquely outward from the light-emitting panel 11, and a current-regulating and voltage-regulating module 13 for input to the solar module 4. The LED beads or LED sheets are integrated into a high-intensity light source 1, saving power consumption and increasing the lighting time through LED lighting technology. The current-regulating and voltage-regulating module 13 is used to regulate and stabilize the current input from the solar module 4. The light is supplied to the light source 1 and connected to the circuit. The light-emitting panel 11 illuminates from the narrow end of the light-expanding inner cover 12 toward the expanding end of the light-expanding inner cover 12. The light intensity is further focused by the light-expanding inner cover 12 to reduce light scattering loss. The expanding end is located near the structural surface a. The structural surface b has heat dissipation ribs 22 for lighting heat dissipation. The heat dissipation ribs 22 are used to dissipate heat from the lamp body when the light source 1 is irradiated for a long time, reducing the impact of overheating on the lighting effect. The heat dissipation ribs 22 preferably adopt a long strip-shaped fin structure with parallel spacing to increase the heat dissipation area.

[0049] Furthermore, as another embodiment 108 of embodiment 105, as shown in FIG5, the structural surface a is equipped with a first transparent element 23 for illumination transmission and protection of the light source 1, and the structural surface e is equipped with a second transparent element 43 for absorption transmission and module protection. The first transparent element 23 and the second transparent element 43 are preferably made of transparent materials such as glass or acrylic. The thickness of the first transparent element 23 is preferably greater than the thickness of the second transparent element 43, so that the light source 1 has a better protection effect against impact and reduces the influence of the transparent element on solar energy absorption. The surfaces of the first transparent element 23 and the second transparent element 43 are both smooth, and their surface roughness is preferably controlled to Ra0.4 or below.

[0050] Further, as another embodiment 108 of embodiment 105, as shown in FIG5, the hinge has a shaft arm 211 for hinge, the shaft arm 211 passing through the bracket hinge portion 35, the housing hinge portion 21 and the module hinge portion 42 respectively, so that the lamp body bracket 3, the lamp body housing 2 and the solar module 4 can rotate coaxially. The shaft arm 211 is a shaft structure extending from the hinge for passing through the hinge hole position. The lamp body housing 2, the lamp body bracket 3 and the solar module 4 all slide and rotate around the central axis of the shaft arm 211 on the outer surface of the shaft arm 211. The center of rotation is restricted by the shaft arm 211. The end of the hinge near the outer side has an anti-slip structure 212 for easy screwing. The anti-slip structure 212 makes it easy for the user to manually screw the hinge to insert or pull the shaft arm 211 into or out of the hinge hole position during installation or disassembly.

[0051] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
