Description

Technical Field

[0001] The invention belongs to the technical field of lamp structures, and in particular relates to a circularly focusing solar spotlight. Background Art

[0002] Solar spotlights use sunlight as energy during the day, use solar energy to charge batteries, and convert solar energy into chemical energy and store it in the batteries. When used at night, the batteries are used as a power source to provide energy for the spotlights, converting the chemical energy in the batteries into light energy to make the spotlights work. They are widely used in places that require lighting, such as landscapes, warehouses, corridors and garages.

[0003] In many application scenarios, solar spotlights need to adjust the focusing focal length to adjust the lighting effect of the solar spotlights. However, most of the current solar spotlights do not have a focusing function. Even if the solar spotlights have a focusing function, the focusing operation is cumbersome. During the focusing process, the frame connected to the lens will move with it. Over time, the lamp structure is easily damaged, and cyclic focusing cannot be achieved, that is, the focal length cannot be cyclically changed in a single adjustment direction, which directly leads to limited application scenarios. Especially in scenarios such as private garages, car owners may move in different locations in the private garage at night, and the distance between them and the spotlights varies. There is a great demand for adjusting the focal length of the spotlight, and the ability to automatically save energy must also be considered. The current solar spotlights cannot meet people's growing application needs, even including the needs of surveillance cameras. Summary of the Invention

[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0039] The applicant's research found that:

[0040] Taking the solar spotlights in private garages as an example, the solar spotlights need to have effective lighting at multiple angles, directions, and distances. First of all, users need the solar spotlights to have the function of cyclically adjusting the focal length to adjust the lighting effect of the lighting area, and the solar spotlights must have a reliable structure and simple adjustment operation. In addition, when people enter and exit the private garage, the solar spotlights need to illuminate accordingly to avoid the problem of energy waste caused by long-term lighting. Therefore, the solar spotlights must also have the ability to adjust at multiple angles and directions to facilitate lighting of different areas. Of course, if it is necessary to monitor the private garage, it can be used in conjunction with a shooting model to provide appropriate lighting, store, or send the required images.

[0041] In view of this, refer to Figures 1 to 14In the present disclosure, a circular focusing solar spotlight is provided, comprising a shell 1, an adjusting knob 2, a first mounting plate 3, an LED lamp group 4 and a lens 5. The adjusting knob 2 is rotatably connected to the shell 1, the first mounting plate 3 is slidingly connected to the shell 1, the lens 5 is fixed to the shell 1, the adjusting knob 2 and the first mounting plate 3 are both mounted on the same side of the shell 1, the lens 5 is mounted on the other side of the shell 1, the LED lamp group 4 is fixed to the first mounting plate 3, the LED lamp group 4 and the lens 5 are clearance-fitted along the axial direction of direct light, the adjusting knob 2 is provided with a slide groove 21, the slide groove 21 is open along the circumferential direction of direct light, the first mounting plate 3 is provided with a protrusion 31 embedded in the slide groove 21, the adjusting knob 2 is used to adjust the distance between the LED lamp group 4 and the lens 5, and the projection of the slide groove 21 on the horizontal plane including the axial center line of the direct light direction is a closed loop shape.

[0042] It should be noted that when the adjusting knob 2 is rotated, it is subject to the limiting sliding connection of the chute 21 and the protrusion 31. The opening direction of the chute 21 is circumferential, and the change of the track is in the axial direction. As the adjusting knob 2 is rotated, the intersection point of the chute 21 and the protrusion 31 is in a straight line projection point of the axial center line, and the limiting direction of the first mounting plate 3 and the housing 1 is axial. Therefore, the protrusion 31 moves back and forth in a straight line in the axial direction without rotating, thereby realizing the conversion of unidirectional rotational motion into linear reciprocating motion. In addition, as an embodiment, in order to To improve the smoothness of the cycle, the closed loop shape is an elliptical or circular shape, which has two advantages. The first is that when the travel in the upward and downward directions transition, the smooth lines at both ends of the ellipse are used to achieve a smooth transition without jamming. The second is to use time as the horizontal axis and the position of the protrusion 31 as the vertical axis to establish a coordinate system. It can be seen that it is a sine curve, which ensures that the position of the protrusion 31 along the axial direction is constant under the same rotation angle of the adjustment knob 2, that is, to ensure the uniformity of the movement. The conversion from rotational motion to linear motion is a linear conversion, which helps to linearly adjust the focal length.

[0043] Reference Figures 5 to 13In this embodiment, the housing 1 includes a bottom shell 11 and a surface shell 12. The surface shell 12 is detachably connected to the bottom shell 11. The adjusting knob 2 is rotatably connected to the bottom shell 11. The adjusting knob 2 and the first mounting plate 3 are connected to the bottom shell 11. The main moving parts are concentrated on the bottom shell 11, and the stationary lens 5 is connected to the surface shell 12. The movement and static are separated. Among them, the bottom shell 11 is provided with a positioning column 13 and a limiting groove 14. The first mounting plate 3 is slidably mounted on the positioning column 13. The first mounting plate 3 also includes a limiting block 32 that is limitedly slidably connected to the limiting groove 14. It should be noted that a connecting hole column is provided on the first mounting plate 3. The inner diameter of the connecting hole column is larger than the outer diameter of the positioning column 13. The connecting hole column is sleeved outside the positioning column 13. The first mounting plate 3 can be here The first mounting plate 3 is limited by the positioning column 13 and makes axial linear movement. However, since the first mounting plate 3 may rotate only with the cooperation of the connecting hole column and the positioning column 13, the sliding connection relationship between the limiting groove 14 and the limiting block 32 is also used to prevent the first mounting plate 3 from rotating around the positioning column 13. In addition, as for the limited sliding connection relationship between the first mounting plate 3 and the bottom shell 11, more specifically, a plurality of limiting columns are provided on the bottom shell 11, and a plurality of limiting sleeves are correspondingly provided on the first mounting plate 3. The limiting sleeves are provided on the limiting columns, and the limiting sleeves are slidably connected to the limiting columns. The extension direction of the limiting column is the axial direction of the direct light. Under the cooperation of the adjusting knob 2 and the protrusion 31, the limiting sleeve makes a linear reciprocating movement on the limiting column.

[0044] As an embodiment, a guide groove is provided on the inner wall of the first mounting plate 3 that cooperates with the positioning column 13, that is, a guide groove is provided on the inner wall of the connecting hole column, and a guide bar 15 that cooperates with the guide groove is provided on the outer wall of the positioning column 13. The cooperation direction of the guide groove and the guide bar 15 is axial direction, which is convenient for installation and disassembly, and also prevents possible rotational displacement between the connecting hole column and the positioning column 13, thereby improving the cooperation strength.

[0045] As an embodiment, a limit baffle is further provided on the inner wall where the first mounting plate 3 cooperates with the positioning column 13, that is, a limit baffle is provided on the inner wall of the connecting hole column, and this limit baffle is parallel to the end face of the positioning column 13. The limit baffle is used to limit the connection with the positioning column 13 when the adjustment knob 2 is rotated to the minimum stroke. At the minimum stroke, the distance between the LED lamp group 4 and the lens 5 is the largest, that is, in order to avoid structural failure, the first mounting plate 3 is further compressed under the action of external force. The problem of structural damage may occur, even if the first mounting plate 3 and the positioning column 13 are further compressed, there is a limit baffle to block it to prevent damage to the LED lamp group 4.

[0046] In this embodiment, the lens 5 is a convex lens 5, and the horizontal distance between the vertical plane where the LED light group 4 is located and the optical center of the lens 5 ranges from 2mm to 10mm. Taking into account the adjustment effect and the size of the solar spotlight, the horizontal distance between the LED light group 4 and the optical center of the lens 5 is limited, and the optimal range is between 2mm and 10mm.

[0047] In this embodiment, a second mounting plate 6 is further included, through which the lens 5 is fixed to the face shell 12. The face shell 12 is provided with a through hole 16 for exposing the lens 5. A clamping groove is provided on the second mounting plate 6, and the outer edge of the lens 5 is a clamping strip. Through the cooperation of the clamping groove and the clamping strip, the second mounting plate 6 clamps the lens 5 between it and the face shell 12.

[0048] Combine Figure 15 In this embodiment, it also includes a photovoltaic panel 71, a battery 72 and a control unit 73. The photovoltaic panel 71 is electrically connected to the battery 72, the battery 72 is electrically connected to the control unit 73, and the control unit 73 is electrically connected to the LED lamp group 4. The photovoltaic panel 71 converts solar energy into chemical energy and stores it in the battery 72, and the battery 72 supplies power to the control unit 73. In combination with actual usage scenarios, the photovoltaic panel 71 can be directly connected to the shell 1 through a structure and placed outdoors together, while integrating the two functions of absorbing solar energy and emitting light into one. It can also adopt a split structure, that is, the photovoltaic panel 71 is independently arranged outdoors, and the shell 1 with the adjustment knob 2, LED lamp group 4 and lens 5 is placed indoors, and the photovoltaic panel 71 can be connected to the battery 72 indoors through a wire.

[0049] As an embodiment, it also includes a human body sensing module 8, which is fixed to the lower part of the shell 1. The human body sensing module 8 includes an infrared sensing unit 81 and a timing unit 82. The infrared sensing unit 81 and the timing unit 82 are electrically connected to the control unit 73 respectively. The infrared sensing unit is used to sense the human body signal in the target area. The control unit 73 is configured to control the LED light group 4 to switch to the high-brightness mode according to the human body signal. The timing unit 82 is used to adjust the delay time of the LED light group 4 to recover from the high-brightness mode to the low-brightness mode, wherein the high-brightness mode and the low-brightness mode are achieved by adjusting the working current input into the LED light group 4 to adjust the brightness.

[0050] It should be noted that a switch is provided on the back of the bottom shell 11, which controls three modes, namely, always on, always off and sensing mode. In the always on mode, the LED light group 4 remains fully on, which is a strong light mode; in the always off mode, the LED light group 4 remains off; in the sensing mode, the infrared sensing unit 81 is used to sense whether there is a human body signal in the target area. When someone is active, the LED light group 4 is controlled to switch to the strong light mode to ensure the lighting effect. When the person leaves the target area and the delay time is reached, it automatically switches to the weak light mode to reduce the lighting brightness, with significant energy-saving effect. The timing unit 82 has a control switch for switching the delay time, including two delay times of 17 seconds and 33 seconds.

[0051] In addition, a photography module is also included. In the sensing mode, when the infrared sensing unit 81 senses a human signal in the target area, the LED light group 4 and the photography module are triggered at the same time. When the LED light group 4 switches to the high-brightness mode, the photography module also starts working to capture the image of the target area. When there is no human signal in the target area, the LED light group 4 automatically switches to the low-brightness mode.

[0052] Combine Figure 2 In this embodiment, it also includes a fixed bracket 91, and the shell 1 is connected to the fixed bracket 91 through a first connecting rod 92. The first connecting rod 92 is horizontally rotatably connected to the fixed bracket 91, that is, when the fixed bracket 91 is placed horizontally, the first connecting rod 92 is placed vertically, and the first connecting rod 92 can rotate horizontally, thereby driving the shell 1 to rotate horizontally, providing a first-dimensional rotation. At the same time, the shell 1 is hinged to the first connecting rod 92, and the shell 1 can be flipped up and down relative to the hinge point between it and the first connecting rod 92, providing a second-dimensional rotation; the human body sensing module 8 is hinged to the first connecting rod 92 through a second connecting rod 93, and the first connecting rod 92, the second connecting rod 93 and the shell 1 are hinged at the same time at a connection point. The up and down rotation between the second connecting rod 93 and the shell 1 is relatively independent and does not affect each other. The second connecting rod 93 can be flipped up and down around this connection point. The human body sensing module 8 is horizontally rotatably connected to the second connecting rod 93, that is, the human body sensing module 8 also has two-dimensional rotation.

[0053] In addition, as another preferred method, the driving method of the adjustment knob 2 also includes motor drive, which uses the motor to drive the rotation of the adjustment knob 2. The motor is connected to the control terminal signal, and the control terminal can remotely adjust the operation of the motor, and then adjust the rotation of the adjustment knob 2 to adjust the focal length and realize remote monitoring. Especially in some outdoor power facilities where there are incomplete and deserted scenes, solar energy is used to store energy, and then the LED light group 4 is controlled to light up when someone passes by for lighting, and monitoring is carried out in conjunction with the photography module. The light focus can also be adjusted through the remote control terminal to ensure the shooting effect.

[0054] Compared with the prior art, the present invention provides a solar spotlight with cyclic focusing. By rotating the adjusting knob 2, the protrusion 31 on the first mounting plate 3 slides cyclically in the slide groove 21 of the adjusting knob 2. On the central axis of the LED lamp group 4 and the lens 5, as the front and rear axial positions of the first mounting plate 3 reciprocate, the focal length between the LED lamp group 4 and the lens 5 is cyclically adjusted. When the outer shell 1 and the lens 5 remain stationary, the cyclic focusing function is achieved only by driving the first mounting plate 3. The structure is simple, the adjustment is reliable, and it can be coordinated with manual control and automatic control, which expands the application scenarios.

[0055] The present invention uses an infrared sensing unit to sense human body signals in the target area. When there is activity, the LED light group 4 is controlled to switch to a strong light mode to ensure the lighting effect. When the person leaves the target area and the delay time is reached, it automatically switches to a weak light mode to reduce the lighting brightness, with significant energy-saving effect.

[0056] According to the needs of users, the solar spotlight of the present invention can be adjusted at multiple angles to adapt to different lighting direction requirements. Especially in garage scenes, it can meet the effective lighting needs of multiple angles, multiple directions and multiple distances according to the different positions of the active personnel, thereby improving the user experience.

[0057] Finally, it should be emphasized that the present invention is not limited to the above-mentioned embodiments. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
