Description

Technical Field

[0001] This invention belongs to the field of lighting technology, specifically relating to a portable outdoor lamp. Background Technology

[0002] With the increasing number of outdoor leisure activities and outdoor work, the performance requirements of outdoor lights, as key lighting equipment, are constantly rising. Currently, there are many types of outdoor lights on the market, but most outdoor lights adopt an integrated fixed structure, which is large and heavy, making them inconvenient to carry or move. This is especially true for outdoor workers and campers who need to carry lights over long distances or frequently move their lighting positions, resulting in a poor user experience. Secondly, the flexibility of lighting angle adjustment is insufficient. The lighting angle of existing outdoor lights is mostly fixed or adjustable within a small range, and the adjustment mechanism is simply designed, making it impossible to achieve multi-angle and all-round lighting adjustment according to the actual lighting needs of outdoor scenarios. For example, when camping, it is necessary to illuminate different areas around the tent, or when working outdoors, precise lighting is needed for different work points. Existing outdoor lights cannot meet these diverse needs. Therefore, there is an urgent need for a portable outdoor light to solve the above problems. Summary of the Invention

[0003] In view of the problems raised in the background art above, the object of the present invention is to provide a portable outdoor lamp.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: A portable outdoor lamp includes a housing, which is a hollow cuboid. A lampshade is mounted on the upper side of the interior of the housing, and a lamp bead substrate is mounted on the bottom of the lampshade. Several LED beads are mounted on the lamp bead substrate. A transparent cover is mounted on the top of the lampshade. Several heat dissipation fins are mounted on the bottom of the lamp bead substrate. A solar photovoltaic panel is mounted on the lower interior of the housing. The solar photovoltaic panel is connected to a battery, which is installed inside the housing and electrically connected to the lamp bead substrate. Heat dissipation grooves are provided on both sides of the housing. Handles are provided on both sides of the bottom of the housing. Connecting seats are mounted on both sides of the handles. A length adjustment component is mounted on the top of the connecting seats. A movable adjustment mechanism is mounted on the top of the length adjustment component and is movably mounted on the side of the housing.

[0005] Further specifying, the movable adjustment mechanism includes a bearing mounted on the housing, a rotating rod rotatably mounted within the bearing, a locking block mounted on the outer side of the rotating rod, a movable rod mounted on the rotating rod, an assembly groove on the lower side of the movable rod, a spring installed within the assembly groove, a limit plate connected to the free end of the spring, a positioning rod installed within the limit plate, one side of the positioning rod penetrating the movable rod and extending to its outer side, a pull plate mounted on the outer side of the positioning rod, and the other side of the positioning rod extending into the housing. The housing has an annular guide groove corresponding to the positioning rod, and a plurality of evenly arranged positioning holes are provided on the inner side of the annular guide groove. The end of the positioning rod is positioned within a positioning hole. This structural design facilitates movable adjustment.

[0006] Furthermore, a first threaded post is mounted on the outer side of the rotating rod, and a first threaded hole matching the first threaded post is provided on the locking block. The locking block is rotated and locked onto the first threaded post through the first threaded hole. This structural design facilitates installation and fixation.

[0007] Further specifying, the length adjustment assembly includes an adjustment sleeve installed at the bottom of the movable rod. An adjustment seat is installed on the lower side of the adjustment sleeve, and the adjustment seat has an adjustment groove. A rotating wheel is rotatably installed in the adjustment groove. One side of the rotating wheel is located on the outer side of the adjustment seat, and the other side of the rotating wheel has an anti-slip protrusion. Miniature springs are installed on both sides inside the adjustment groove. The free ends of the miniature springs are connected to anti-slip blocks. An adjustment movable seat is installed on the side of the anti-slip block corresponding to the anti-slip protrusion. The adjustment movable seat has an arc-shaped groove. The rotating wheel and the anti-slip protrusion are both rotatably positioned within the arc-shaped groove. An arc-shaped rubber strip is provided on the other side of the anti-slip block. The adjustment sleeve has a guide groove at the corresponding anti-slip block position, and the anti-slip block is slidably positioned within the guide groove. An adjustment rod is slidably installed inside the adjustment sleeve, and the adjustment rod has an arc-shaped groove at the corresponding arc-shaped rubber strip position. This structural design facilitates length adjustment.

[0008] Further specifying, the top of the adjusting sleeve is equipped with a second threaded post, and the bottom of the movable rod is provided with a second threaded hole that matches the second threaded post. The adjusting sleeve is locked in the second threaded hole at the bottom of the movable rod by the second threaded post. The bottom of the adjusting rod is provided with a third threaded hole, and a third threaded post is installed in the third threaded hole. The bottom of the third threaded post is fixedly installed on the connecting seat. This structural design facilitates connection and installation.

[0009] Furthermore, the handle is rotatably mounted on both sides within the connecting seat, and the surface of the handle is provided with anti-slip stripes. This structural design facilitates operation and use.

[0010] Furthermore, the lampshade contains two symmetrical long reflective light-emitting surfaces and two symmetrical short reflective light-emitting surfaces. The angle between the two symmetrical long reflective light-emitting surfaces is [degree], and the angle between the two symmetrical short reflective light-emitting surfaces is [degree]. This structural design disperses the lighting light, resulting in more uniform overall brightness.

[0011] Furthermore, a battery mounting bracket is installed on the outside of the battery, and the battery mounting bracket is installed inside the housing. An airflow channel is formed between the side wall of the battery mounting bracket and the inner wall of the housing, and the airflow channel is located between the heat dissipation slots on both sides. This structural design facilitates fixed installation.

[0012] Furthermore, the bottom of the LED substrate is connected to the heat dissipation fins via thermally conductive silicone grease, and a heat dissipation channel is formed between the two heat dissipation fins, which is located between the heat dissipation slots on both sides. This structural design facilitates airflow and heat dissipation.

[0013] Furthermore, a waterproof and dustproof mesh is installed inside the heat dissipation groove, and an exhaust fan is installed inside the heat dissipation groove on one side of the outer casing. The exhaust fan is electrically connected to the battery. This structural design improves the waterproof and dustproof effect while allowing air circulation for heat dissipation.

[0014] The beneficial effects of this invention are as follows: 1. This invention achieves flexible adjustment of the lighting angle by setting up an adjustable mechanism. The movable rod can rotate within the bearing through a rotating rod. With the precise positioning of the positioning rod and multiple positioning holes in the annular guide groove, it can be stably fixed at different rotation angles, driving the outer shell to switch the lighting direction. This meets the diverse lighting needs of illuminating different areas around the tent during camping and accurately targeting different work points during outdoor operations. At the same time, combined with the length adjustment component, it can flexibly adjust the lighting height and support status, which can not only support and fix the equipment at a suitable height to improve the lighting coverage, but also adapt to the height requirements of different placement surfaces.

[0015] 2. This invention adopts a power supply mode that combines solar photovoltaic panels and batteries. During the day, the solar photovoltaic panels can absorb solar energy and convert it into electrical energy stored in the batteries. At night, the batteries power the LEDs, realizing green energy recycling and reducing dependence on external power sources. It is especially suitable for outdoor scenarios without mains power supply and greatly improves battery life.

[0016] 3. This invention provides a heat dissipation fin on the bottom of the LED substrate, using thermal grease to fill the gaps, allowing the heat generated by the LED substrate and LEDs to be quickly transferred to the heat dissipation fins. At the same time, a heat dissipation channel is formed between the heat dissipation fins, and an airflow channel is formed between the side wall of the battery holder and the inner wall of the outer casing. Both types of channels are connected to the heat dissipation slots on both sides, enabling rapid heat dissipation. Additionally, an exhaust fan is installed at one side of the heat dissipation slot, which can actively drive airflow through the airflow channel and the heat dissipation channel to form a forced convection circulation, accelerating the heat dissipation speed and preventing heat accumulation inside the device.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Example 1, such as Figure 1 , Figure 2 and Figure 3 As shown, a portable outdoor lamp has a hollow rectangular shell 1. A lampshade 2 is installed on the upper side of the interior of the shell 1, and a lamp bead substrate 3 is installed on the bottom of the lampshade 2. Several LED beads 4 are installed on the lamp bead substrate 3. A transparent cover plate 5 is installed on the top of the lampshade 2. Several heat dissipation fins 6 are installed on the bottom of the lamp bead substrate 3. A solar photovoltaic panel 7 is installed on the lower side of the interior of the shell 1. The solar photovoltaic panel 7 is connected to a battery 8, which is installed inside the shell 1 and electrically connected to the lamp bead substrate 3. Heat dissipation grooves 9 are provided on both sides of the shell 1. Handles 10 are provided on both sides of the bottom of the shell 1. Connecting seats 11 are installed on both sides of the handles 10. A length adjustment component 12 is installed on the top of the connecting seat 11. A movable adjustment mechanism 13 is installed on the top of the length adjustment component 12 and is movably installed on the side of the shell 1.

[0020] In this embodiment, when moving, the user can directly carry the device to the target location via the handle 10. According to the lighting requirements, the length adjustment component 12 and the movable adjustment mechanism 13 can be adjusted so that the length adjustment component 12 supports the outer shell 1 and can adjust the lighting angle and height of the LED beads 4. During the day, the solar photovoltaic panel 7 absorbs solar energy and converts it into electrical energy and stores it in the battery 8. When using it at night, the switch is turned on, the battery 8 supplies power to the LED bead substrate 3, and the LED beads 4 emit light. During operation, the heat generated by the LED bead substrate 3 is discharged through the heat dissipation fins 6 and dissipated to the external environment through the heat dissipation grooves 9, achieving efficient heat dissipation.

[0021] The height of the housing 1 can be adjusted by rotating the movable adjustment mechanism 13 and adjusting the length of the component 12. The two work together to achieve all-round adjustment of the lighting angle, which can accurately adapt to the lighting needs of different outdoor scenarios.

[0022] The outer shell 1 is made of ABS engineering plastic, which has good impact resistance and waterproof performance. The connection between the lampshade 3 and the outer shell 1 is abutted with a nitrile rubber sealing ring, with a sealing rating of IP54, which can effectively prevent outdoor dust and rainwater from entering. The lamp bead substrate 3 is fixedly installed on the bottom wall of the lampshade 2 by M3 bolts. Several LED beads 4 are evenly arrayed and welded on the lamp bead substrate 3. The LED beads 4 are connected in series. The back of the outer shell 1 is detachably connected to a solar photovoltaic panel 7 by M4 bolts. The solar photovoltaic panel 7 is adapted to the size of the back of the outer shell 1. Red and black positive and negative wires are welded to the output end of the solar photovoltaic panel 7. The wires extend into the inside of the outer shell 1 and are connected to the positive and negative input terminals of the battery 8 through terminal blocks. A TP4056 charging protection module is connected in series on the wires to prevent the battery 8 from overcharging and over-discharging. The positive and negative output terminals of the battery 8 are connected to the lamp bead substrate 3 through wires. A switch is connected in series on the wires and is embedded in the outer shell 1 for easy operation by the user.

[0023] Example 2, as Figure 1 , Figure 3 and Figure 4 As shown, this embodiment adds the following structure based on embodiment 1: the movable adjustment mechanism 13 includes a bearing 14 mounted on the outer shell 1, a rotating rod 15 rotatably mounted inside the bearing 14, a locking block 16 mounted on the outer side of the rotating rod 15, a movable rod 17 mounted on the rotating rod 15, an assembly groove 18 provided on the lower side of the movable rod 17, a spring 19 installed in the assembly groove 18, a limit plate 20 connected to the free end of the spring 19, a positioning rod 21 installed in the limit plate 20, one side of the positioning rod 21 passing through the movable rod 17 and extending to its outer side, a pull plate 211 installed on the outer side of the positioning rod 21, and the other side of the positioning rod 21 extending into the outer shell 1. The outer shell 1 is provided with an annular guide groove 22 at the corresponding positioning rod 21, and a plurality of evenly arranged positioning holes 23 are provided on the inner side of the annular guide groove 22. The end of the positioning rod 21 is set in the positioning hole 23.

[0024] In this embodiment, by rotating the movable rod 17, the movable rod 17 drives the length adjustment component 12. When the length adjustment component 12 drives the handle 10 towards the transparent cover plate 5 through the connecting seat 11, the solar photovoltaic panel 7 is on the upper side. The solar photovoltaic panel 7 can absorb solar energy and convert it into electrical energy and store it in the battery 8. When the movable rod 17 is rotated, the movable rod 17 drives the length adjustment component 12. When the length adjustment component 12 drives the handle 10 towards the solar photovoltaic panel 7 through the connecting seat 11, the transparent cover plate 5 is on the upper side. When the switch is turned on, the battery 8 supplies power to the LED bead substrate 3, and the LED bead 4 emits light.

[0025] During operation, by pulling the pull plate 211 outward, the pull plate 211 drives the positioning rod 21, which in turn drives the limiting plate 20 backward, causing the front end of the positioning rod 21 to exit the positioning hole 23. Simultaneously, the limiting plate 20 compresses the spring 19. Then, the movable rod 17 is rotated, causing it to rotate within the bearing 14 via the rotating rod 15. This causes the positioning rod 21 to move within the annular guide groove 22. After reaching the appropriate position, the pull plate 211 is released, causing the spring 19 to rebound. The end of the positioning rod 21 is then inserted into the positioning hole 23, thus completing the fixation. By adjusting the movable rod 17, the length adjustment component 12 can be driven, which in turn drives the handle 10 to change position, allowing for different placement requirements and enabling multi-angle, all-around lighting adjustment.

[0026] Example 3, as Figure 4 As shown, this embodiment adds the following structure to the embodiment 2: a first threaded post 24 is installed on the outer side of the rotating rod 15, and a first threaded hole 25 matching the first threaded post 24 is provided on the locking block 16. The locking block 16 is rotated and locked onto the first threaded post 24 through the first threaded hole 25.

[0027] In this embodiment, when installing before use or when disassembling and maintaining after use, the locking block 16 is rotated to move the first threaded hole 25 along the first threaded post 24, thereby realizing the installation and disassembly of the locking block 16, so as to fix and disassemble the movable rod 17.

[0028] Example 4, as Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, this embodiment adds the following structure based on embodiment 1: the length adjustment assembly 12 includes an adjustment sleeve 26 installed at the bottom of the movable rod 17, an adjustment seat 27 installed on the lower side of the adjustment sleeve 26, an adjustment groove 28 provided in the adjustment seat 27, a rotating wheel 29 rotatably installed in the adjustment groove 28, one side of the rotating wheel 29 being located on the outside of the adjustment seat 27, and an anti-slip protrusion 30 provided on the other side of the rotating wheel 29. Miniature springs 31 are installed on both sides inside the adjustment groove 28, and the free end of the miniature springs 31 is connected to an anti-slip block 3. 2. An adjustable seat 33 is installed on one side of the anti-slip protrusion 30 on the anti-slip slider 32. The adjustable seat 33 is provided with an arc-shaped groove 34. The rotating wheel 29 and the anti-slip protrusion 30 are both rotatably arranged in the arc-shaped groove 34. An arc-shaped rubber strip 35 is provided on the other side of the anti-slip slider 32. The adjusting sleeve 26 is provided with a guide groove 36 at the corresponding anti-slip slider 32. The anti-slip slider 32 is slidably arranged in the guide groove 36. An adjusting rod 37 is slidably installed in the adjusting sleeve 26. The adjusting rod 37 is provided with an arc-shaped groove 38 at the corresponding arc-shaped rubber strip 35.

[0029] In this embodiment, when the length needs to be adjusted for use, first rotate the wheel 29 so that the wheel 29 drives the anti-slip protrusion 30 to be removed from the arc groove 34 on the adjusting seat 33. At this time, the anti-slip block 32 loses its squeezing force, and the micro spring 31 will drive the anti-slip block 32. The anti-slip block 32 drives the arc rubber strip 35 to move upward and be removed from the arc groove 38. Then the handle 10 can be dragged. The handle 10 drives the connecting seat 11, and the connecting seat 11 drives the adjusting rod 37 to slide out from the adjusting sleeve 26. The length of the handles 10 on both sides can be adjusted. After adjusting to a suitable distance, rotate the wheel 29 in the opposite direction so that the wheel 29 drives the anti-slip protrusion 30 to rotate into the arc groove 34 on the adjusting seat 33. The adjusting seat 33 moves downward after being subjected to force, pushing the anti-slip block 32. The anti-slip block 32 slides in the guide groove 36 and pushes the arc rubber strip 35 into the arc groove 38 on the adjusting rod 37 to increase friction and achieve fixation.

[0030] Example 5, as Figure 4 and Figure 5 As shown, this embodiment adds the following structure based on embodiment 4: a second threaded post 39 is installed on the top of the adjusting sleeve 26, and a second threaded hole 40 matching the second threaded post 39 is provided at the bottom of the movable rod 17. The adjusting sleeve 26 is locked in the second threaded hole 40 at the bottom of the movable rod 17 by the second threaded post 39. A third threaded hole 41 is provided at the bottom of the adjusting rod 37, and a third threaded post 42 is installed in the third threaded hole 41. The bottom of the third threaded post 42 is fixedly installed on the connecting seat 11.

[0031] In this embodiment, when connected for use, the adjusting sleeve 26 is installed into the second threaded hole 40 at the bottom of the movable rod 17 through the second threaded post 39 at the top, so as to achieve a fixed connection. The third threaded post 42 at the top of the connecting seat 11 is rotated into the middle of the bottom of the adjusting rod 37, so that the handle 10 is connected and installed. Furthermore, through the connection method of the thread and the threaded post, different types and sizes of adjusting sleeve 26 and connecting seat 11 can be replaced for use in subsequent use.

[0032] Example 6, as Figure 1 , Figure 3 and Figure 5 As shown, this embodiment adds the following structure based on embodiment 1: the two sides of the handle 10 are rotatably installed in the connecting seat 11, and the surface of the handle 10 is provided with anti-slip stripes 43.

[0033] In this embodiment, during use, when the two handles 10 are placed on the ground to support the photo, or when solar charging is performed, the profile rollers can push the outer shell 1 to move its position. The anti-slip stripes 43 on the handles 10 increase the frictional resistance between the hand and the contact surface of the handles 10, preventing slippage when holding.

[0034] Example 7, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure to the embodiment 1: the lampshade 2 is provided with two symmetrical long reflective light-emitting surfaces 201 and two symmetrical short reflective light-emitting surfaces 202. The included angle between the two symmetrical long reflective light-emitting surfaces 201 is 50 degrees, and the included angle between the two symmetrical short reflective light-emitting surfaces 202 is 50 degrees.

[0035] In this embodiment, during use, the long reflective light-emitting surface 201 can directionally reflect the light emitted by the LED beads 4, covering the main irradiation area, while the short reflective light-emitting surface 202 can perform secondary reflection of the scattered light from the edge of the light source, supplementing the edge part of the irradiation area. The 50-degree angle design enables the reflected light to form a complementary and superimposed light field, avoiding local over-brightness or under-brightness, while reducing glare caused by direct light, achieving uniform brightness in the entire irradiation area, and improving visual comfort.

[0036] Example 8, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure to the embodiment 1: a battery mounting bracket 44 is installed on the outside of the battery 8, the battery mounting bracket 44 is installed inside the outer casing 1, and an air flow channel 45 is formed between the side wall of the battery mounting bracket 44 and the inner wall of the outer casing 1. The air flow channel 45 is arranged between the heat dissipation slots 9 on both sides.

[0037] In this embodiment, during installation, the battery 8 is fixedly installed inside the housing 1 by the battery mounting bracket 44. At the same time, an air flow channel 45 is formed between the side wall of the battery mounting bracket 44 and the inner wall of the housing 1, which allows the internal air to circulate during heat dissipation and improves the heat dissipation effect.

[0038] Example 9, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure based on embodiment 1: the bottom of the LED substrate 3 is connected to the heat dissipation fins 6 through thermally conductive silicone grease, and a heat dissipation channel 46 is formed between the two heat dissipation fins 6. The heat dissipation channel 46 is disposed between the heat dissipation grooves 9 on both sides.

[0039] In this embodiment, during use, the LED substrate 3 and the heat sink fins 6 are connected by thermal grease. The thermal grease can fully fill the microscopic gap between the bottom of the LED substrate 3 and the surface of the fins, so that the heat of the LED substrate 3 and the LED LED 4 can be quickly and directly transferred to the heat sink fins 6. In addition, the heat dissipation channel 46 formed between the two heat sink fins 6 provides a directional channel for airflow. The heat dissipation channel 46 can guide the convective airflow or forced convective airflow (in conjunction with the exhaust fan 48) through the gap between the fins, take away the heat on the surface of the fins, and avoid the accumulation of heat between the fins.

[0040] Example 10, as Figure 2 As shown, this embodiment adds the following structure based on embodiment 1: a waterproof and dustproof mesh 47 is installed inside the heat dissipation slot 9, and an exhaust fan 48 is installed inside one side of the heat dissipation slot 9 of the outer casing 1. The exhaust fan 48 is electrically connected to the battery 8.

[0041] In this embodiment, during use, the waterproof and dustproof mesh 47 effectively intercepts external dust, water vapor, insects and other impurities from entering the interior of the outer casing 1 without obstructing airflow, preventing impurities from adhering to the surface of the heat dissipation fins 6 or intruding into the LED substrate 3, thus ensuring the unobstructed flow of the heat dissipation channel 46. Meanwhile, the exhaust fan 48 can actively drive airflow through the airflow channel 45 and the heat dissipation channel 46 to form a forced convection circulation. The forced airflow can more quickly remove the heat from the heat dissipation fins 6 and the battery 8, improving the heat dissipation effect.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
