[0040] Example

[0041] like Figure 1 - Figure 4 As shown, the lighting device provided in this embodiment includes a lighting component, a light path channel 20, a first drive component and a second drive component; the lighting component is connected to the light input end of the light path channel 20, the light received by the lighting component can be transmitted to the light path channel 20, the first drive component can drive the lighting component to rotate around the first horizontal direction, and the second drive component can drive the lighting component to swing around the second horizontal direction; the second horizontal direction is at an angle to the first horizontal direction.

[0042] Specifically, the lighting device can be installed on the fixed wallboard 40 when in use to ensure the stability of the installation of the lighting device. Among them, the light path channel 20 is the channel for light transmission. Taking the need to introduce light into an underground building as an example, the light path channel 20 is fixedly installed on the fixed wallboard 40, and passes through the fixed wallboard 40 to communicate with the channel for light transmission inside the building, and then transmits the light to the underground building. Among them, the light path channel 20 can be a cylindrical structure, or a rectangular structure, or a triangular prism structure, as long as it can achieve the transmission of light. However, no matter which structure is adopted, the light path channel 20 has a rotation center line. When the light path channel 20 is a cylindrical structure, the rotation center line of the light path channel 20 is its own axis. In the following specific embodiments, the light path channel 20 is an example of a cylindrical structure. Therefore, the first horizontal direction is the axis of the light path channel 20, the second horizontal direction is perpendicular to the first horizontal direction, and the second horizontal direction is the straight line direction formed by the connection point of the lighting assembly and the light path channel 20.

[0043] The lighting assembly is arranged at the light-inlet end of the optical channel 20, and is used to obtain light, reflect the light into the optical channel 20, and transmit the light along the optical channel 20. The first driving assembly is used to drive the lighting assembly to rotate around the axis of the optical channel 20, and the second driving assembly is used to drive the lighting assembly to swing around the connection point between itself and the optical channel 20. If the fixed wall panel 40 is placed vertically, the optical channel 20 is arranged perpendicular to the fixed wall panel 40, that is, the optical channel 20 is arranged horizontally, and the second driving assembly drives the lighting assembly to swing around the horizontal straight line formed by the connection point between the lighting assembly and the optical channel 20. Figure 2As shown, the extension direction of the optical path channel 20 is the horizontal left and right direction, that is, the first horizontal direction; the horizontal straight line formed by the connecting points is the direction extending perpendicular to the drawing, that is, the second horizontal direction, and the second driving component drives the lighting component to swing left and right around the horizontal straight line.

[0044] The lighting device increases the flexibility of the lighting component by combining the two movements applied to the lighting component, ensuring that the lighting component can make appropriate movements according to the sun's illumination angle, thereby enabling the lighting component to always face the sunlight to gather more sunlight into a light beam for easy transmission along the optical path 20. At the same time, the lighting component facing the sunlight is also convenient for absorbing more solar energy, thereby increasing the utilization rate of solar energy.

[0045] Please continue to refer to Figure 1 - Figure 4 Preferably, the lighting assembly includes a mounting frame 11, a reflecting surface 12 rotatably mounted on the mounting frame 11, and a deceleration mechanism 37 connected between the mounting frame 11 and the reflecting surface 12; the mounting frame 11 is connected to the optical path channel 20, the first driving assembly can drive the mounting frame 11 to rotate around a first horizontal direction, the second driving assembly can drive the mounting frame 11 to swing around a second horizontal direction, and the reflecting surface 12 can reflect the received light to the optical path channel 20; the reflecting surface 12 can rotate synchronously with the mounting frame 11, and at the same time, the swing of the mounting frame 11 can drive the reflecting surface 12 to swing through the deceleration mechanism 37.

[0046] Specifically, the mounting frame 11 is used to ensure that the component that reflects light has good stability. The power output ends of the first drive assembly and the second drive assembly both act on the mounting frame 11, and then the first drive assembly drives the mounting frame 11 to rotate around the first horizontal direction, and the second drive assembly drives the mounting frame 11 to swing left and right around the second horizontal direction, so as to realize two movements of the lighting component. The reflecting surface 12 is the component that reflects the light entering the optical path channel 20. The reflecting surface 12 is arranged at the light input end of the optical path channel 20 and is rotatably connected to the mounting frame 11. At the same time, a speed reduction mechanism 37 is arranged between the reflecting surface 12 and the mounting frame 11. When the second drive assembly drives the mounting frame 11 to swing left and right around the second horizontal direction, the mounting frame 11 transmits the swinging motion to the reflecting surface 12 through the speed reduction mechanism 37, thereby driving the reflecting surface 12 to swing as well. However, precisely because a deceleration mechanism 37 is provided between the mounting frame 11 and the reflecting surface 12, the swing amplitude of the mounting frame 11 is greater than the swing amplitude of the reflecting surface 12, thereby achieving fine adjustment of the angle of the reflecting surface 12 relative to the optical path channel 20 when the reflecting surface 12 moves with the sunlight, so that the reflection center point of the reflecting surface 12 can always be located on the axis of the optical path channel 20.

[0047] Please continue to refer to Figure 3 - Figure 5Preferably, the lighting assembly further includes a first converging surface 13 and a second converging surface 14, and the first converging surface 13 and the second converging surface 14 are both fixed to the mounting frame 11, the first converging surface 13 has a first central axis, the second converging surface 14 has a second central axis, and the first central axis is coaxially arranged with the second central axis; the first converging surface 13, the second converging surface 14 and the reflecting surface 12 sequentially form a reflecting light path. The light reflected by the reflecting surface 12 is parallel to the channel extension direction of the light path channel 20.

[0048] Specifically, the first converging surface 13 and the second converging surface 14 are both used to reflect light, and the two are fixed on the mounting frame 11, so the movement of the mounting frame 11 can drive the first converging surface 13 and the second converging surface 14 to move synchronously. Among them, the first converging surface 13 is used to receive light irradiated by sunlight, and reflect the received light to the second converging surface 14, and the second converging surface 14 can reflect the light to the reflecting surface 12, and then reflect the light to the optical path channel 20 through the reflecting surface 12. Among them, the rotation of the first converging surface 13 rotates with the irradiation direction of sunlight, and its purpose is to make the first converging surface 13 always face the sun, and the sunlight is directly incident on the first converging surface 13, that is, the direction of the sunlight incident on the first converging surface 13 is the same as the direction of the first central axis of the first converging surface 13, so as to maximize the acquisition of solar energy and increase the utilization rate of solar energy.

[0049] Please continue to refer to Figure 3 - Figure 5 Preferably, the first converging surface 13 is a concave surface and has a converging effect; the second converging surface 14 is a convex surface, the second converging surface 14 is located above the concave surface of the first converging surface 13, and the size of the second converging surface 14 is much smaller than the size of the first converging surface 13, so as to converge the light reflected by the first converging surface 13 into a light beam and reflect it to the reflecting surface 12; the reflecting surface 12 is an inclined surface.

[0050] The first central axis of the first converging surface 13 and the second central axis of the second converging surface 14 are the same vertical line, that is, the first converging surface 13 and the second converging surface 14 are coaxially arranged to ensure that the light incident on the first converging surface 13 is parallel to the light emitted from the second converging surface 14. If the light is vertically incident on the first converging surface 13, the light should also be vertically emitted from the second converging surface 14.

[0051] When the first central axis and the second central axis are in a vertical direction, the plumb line of the first central axis, the second central axis and the reflection center point of the reflection surface 12 are located on the same straight line, and the reflection center point of the reflection surface 12 is located on the axis of the optical path channel 20, ensuring that the light can be reflected to the optical path channel 20 to the maximum extent, thereby increasing the utilization rate of solar energy.

[0052] Please continue to refer to Figure 3 - Figure 5In actual use, the first driving assembly and the second driving assembly drive the mounting frame 11 to move so that the first converging surface 13 can face the sunlight. Taking the case where the sunlight is vertically incident on the first converging surface 13 as an example, the first converging surface 13 receives the vertically incident light and reflects it to the second converging surface 14. The second converging surface 14 can reflect the received light to the reflecting surface 12 in a direction parallel to the second central axis, and all reflected light is parallel, that is, the light incident on the reflecting surface 12 is in a vertical direction. The reflection center point of the reflecting surface 12 is located on the axis of the optical path channel 20, and the light incident on the reflecting surface 12 is in a vertical direction, so the light reflected from the reflecting surface 12 to the optical path channel 20 is in a horizontal direction, that is, parallel to the axis of the optical path channel 20.

[0053] The first converging surface 13 is provided with an opening at the bottom thereof, and the opening is located directly below the second converging surface 14 , so that the second converging surface 14 reflects the light to the reflecting surface 12 .

[0054] Please continue to refer to Figure 1 - Figure 4 Preferably, the ratio of the swing angle of the mounting frame 11 to the swing angle of the reflecting surface 12 is 2:1. Specifically, the deceleration mechanism 37 arranged between the mounting frame 11 and the reflecting surface 12 is a two-stage deceleration mechanism, which obtains the swing angle of the reflecting surface 12 by decelerating the swing angle of the mounting frame 11 twice. Moreover, no matter how the reflecting surface 12 swings following the mounting frame 11, it is necessary to make the reflection center point of the reflecting surface 12 located on the axis of the optical path channel 20, and the light reflected from the reflecting surface 12 into the optical path channel 20 is parallel to the axis of the optical path channel 20. If the optical path channel 20 is horizontally arranged, the light emitted from the reflecting surface 12 is in a horizontal state. Moreover, the light incident on the first converging surface 13 is direct sunlight.

[0055] Please continue to refer to Figure 1 - Figure 4 In actual use, the reduction mechanism 37 includes a rotating shaft 371, a first small gear 372, a first large gear 373, a second small gear 374 and a second large gear 375; the reflecting surface 12 is fixedly connected to the rotating shaft 371, and the rotating shaft 371 is rotatably connected to the rotating drum 32; the first small gear 372 is fixedly connected to the mounting frame 11 and is rotatably connected to the rotating shaft 371; the first large gear 373 is meshed with the first small gear 372, and the second small gear 374 rotates coaxially with the first large gear 373; the second large gear 375 is fixedly arranged on the rotating shaft 371 and is meshed with the second small gear 374.

[0056] Specifically, the first small gear 372 and the second large gear 375 are coaxially arranged, and both are arranged on the rotating shaft 371. The first small gear 372 is rotatably connected to the rotating shaft 371, and the second large gear 375 is fixedly connected to the rotating shaft 371. The first small gear 372 is fixedly connected to the mounting frame 11, and then swings synchronously and in the same amplitude with the mounting frame 11; the rotating shaft 371 is fixedly arranged on the reflecting surface 12, and then the reflecting surface 12 can be driven to swing around the axis of the rotating shaft 371 through the rotation of the rotating shaft 371. The first large gear 373 is coaxially arranged with the second small gear 374, and the shaft is rotatably connected to the optical path channel 20, and the rotation of the first large gear 373 can drive the second small gear 374 to rotate synchronously. The first small gear 372 meshes with the first large gear 373 , the second small gear 374 meshes with the second large gear 375 , and the second large gear 375 is fixedly connected to the rotating shaft 371 . The rotation of the second large gear 375 can drive the rotating shaft 371 to rotate, so as to drive the reflecting surface 12 to swing through the rotating shaft 371 .

[0057] In actual use, the mounting frame 11 drives the first pinion 372 to rotate synchronously. The number of teeth of the first pinion 372 is less than the number of teeth of the first large gear 373, and the two are meshed, so the rotation speed of the first large gear 373 is less than the rotation speed of the first pinion 372, which serves as the first deceleration of the swing angle of the mounting frame 11. The first large gear 373 drives the second pinion 374 to rotate synchronously, so the two have the same rotation speed. The number of teeth of the second pinion 374 is less than the number of teeth of the second large gear 375, and the two are meshed, so the rotation speed of the second large gear 375 is less than the rotation speed of the second pinion 374, which serves as the second deceleration of the swing angle of the mounting frame 11. Through two decelerations, the rotation angle of the reflection surface 12 is achieved to be half of the rotation angle of the mounting frame 11, ensuring that the reflection surface 12 can reflect the light in a direction parallel to the axis of the optical path channel 20 into the optical path channel 20 while following the swing of the mounting frame 11, reducing the probability of the light being reflected on the inner wall of the optical path channel 20 during the reflection process, and increasing the utilization rate of the received light.

[0058] Please continue to refer to Figure 1 - Figure 3 Optionally, the second driving assembly includes a telescopic driving member 36 and a connecting plate 35, the telescopic driving member 36 is hinged to the connecting plate 35, and the power output end of the telescopic driving member 36 is hinged to the mounting frame 11, and the telescopic driving member 36 can drive the mounting frame 11 to swing around the connection point with the rotating drum 32.

[0059] Specifically, the telescopic drive member 36 adopts an electric push rod, which is hinged on the connecting plate 35, and the push rod extension end of the electric push rod is hinged to the mounting frame 11, and then the mounting frame 11 is driven to swing around the axis of the rotating shaft 371 through the linear motion of the push rod, thereby realizing the swing adjustment of the reflecting surface 12.

[0060] Please continue to refer to Figure 1 - Figure 4 Optionally, the first driving assembly includes a rotary driving member 31 and a rotating drum 32; the optical path channel 20 is fixed to the fixed wall panel 40, the rotating drum 32 is connected to the optical path channel 20, and the two are coaxially arranged; the mounting frame 11 is connected to the rotating drum 32, the rotary driving member 31 can drive the rotating drum 32 to rotate, and the rotating drum 32 can drive the mounting frame 11 to rotate synchronously.

[0061] Specifically, the rotating drum 32 is connected to the connecting plate 35, the optical path channel 20 is located inside the rotating drum 32, and the optical path channel 20 passes through the connecting plate 35 and is fixedly connected to the fixed wall plate 40. The optical path channel 20 is coaxially arranged with the rotating drum 32, and a fixed arm 321 is arranged at the end of the rotating drum 32 away from the connecting plate 35, the fixed arm 321 extends along the axis direction of the rotating drum 32, and the extended end of the fixed arm 321 is rotatably connected with the mounting frame 11, so that the mounting frame 11 swings around the connection point with the fixed arm 321. The rotating drum 32 is connected to the rotary drive member 31 in a transmission manner, so that the rotating drum 32 is driven to rotate around its own axis through the rotary drive member 31, and then the mounting frame 11 is driven to rotate around the axis of the rotating drum 32 through the fixed arm 321, and the rotation of the mounting frame 11 can drive the first converging surface 13, the second converging surface 14 and the reflecting surface 12 to rotate synchronously around the axis of the rotating drum 32.

[0062] The rotating drum 32 is a cylindrical structure, and the axis thereof is the rotation center line of the rotating drum 32 , which is in the same straight line as the axis of the optical path channel 20 .

[0063] Please continue to refer to Figure 1 - Figure 3 Preferably, the first driving assembly also includes a moving gear 33 and a fixed gear 34; the rotary driving member 31 and the rotating drum 32 are both fixed to the connecting plate 35, and the fixed gear 34 is fixed to the fixed wall panel 40. The power output end of the rotary driving member 31 is transmission-connected to the moving gear 33, and the moving gear 33 is meshed with the fixed gear 34 and can rotate around the fixed gear 34.

[0064] Specifically, the rotary drive member 31 adopts a motor, the motor shaft is connected to the moving gear 33 by transmission, and the rotary drive member 31 is fixed on the connecting plate 35. The fixed gear 34 is fixed on the fixed wall plate 40, and the fixed gear 34 is externally meshed with the moving gear 33. In actual use, the rotary drive member 31 drives the moving gear 33 to rotate, and the moving gear 33 is externally meshed with the fixed gear 34, so that the moving gear 33 rotates around the fixed gear 34. A bearing is provided between the rotating drum 32 and the optical path channel 20, and then the rotating plate 35 and the rotating drum 32 are driven to rotate synchronously through the rotation of the moving gear 33 around the fixed gear 34, so as to realize the rotation of the mounting frame 11 around the axis of the optical path channel 20.

[0065] Please continue to refer to Figure 3 and Figure 4Preferably, the mounting frame 11 includes a connecting ring 111, a connecting arm 112 fixed to the connecting ring 111, and a connecting rod 113 fixed to the connecting ring 111; one end of the connecting arm 112 away from the connecting ring 111 is connected to the optical path channel 20, the connecting ring 111 is sleeved on the first converging surface 13, and the second converging surface 14 is overlapped on the connecting rod 113.

[0066] Specifically, the connecting ring 111 is a circular ring, and the edge of the first converging surface 13 extends out a first edge, and the first edge is a circular ring, and the first edge overlaps the connecting ring 111, so that the connecting ring 111 is sleeved on the outside of the first converging surface 13. At the same time, two parallel connecting rods 113 are fixedly arranged on the connecting ring 111, and the edge of the second converging surface 14 extends out a second edge, and the second edge overlaps the two connecting rods 113, so as to realize the installation of the second converging surface 14.

The two ends of the rotating shaft 371 respectively pass through the connecting arms 112 on the same side, thereby realizing the installation of the mounting frame 11 relative to the rotating shaft 371, so that the mounting frame 11 swings around the axis of the rotating shaft 371 under the power of the telescopic driving member 36.

[0068] Please continue to refer to Figure 1 and Figure 2 In actual use, the lighting assembly further includes a dust cover 15, which is buckled on the mounting frame 11 to protect the first convergence surface 13 and the second convergence surface 14 and reduce the amount of dust accumulated on the first convergence surface 13 and the second convergence surface 14. At the same time, the dust cover 15 is a transparent cover to ensure that light can pass through the dust cover 15 and irradiate the first convergence surface 13.

[0069] Please continue to refer to Figure 3 In actual use, the lighting assembly also includes a sun tracking controller 16, which is disposed on the mounting frame 11 and connected to the first driving assembly and the second driving assembly.

[0070] Specifically, the lighting device further includes a central controller, and the sun tracking controller 16, the rotary drive member 31, and the telescopic drive member 36 are all electrically connected to the central controller. The sun tracking controller 16 detects the irradiation angle signal of the sunlight and transmits the signal to the central controller. After receiving and analyzing the angle signal, the central controller transmits a command signal to the rotary drive member 31 and the telescopic drive member 36, thereby driving the rotary drive member 31 to start to drive the mounting frame 11 to rotate a certain angle, and driving the telescopic drive member 36 to start to drive the mounting frame 11 to swing a certain angle, so that the first converging surface 13 on the mounting frame 11 is always located at the position where the sunlight is directly incident.

[0071] It should be added that the solar tracking controller 16 and the feedback adjustment between the solar tracking controller 16 and the telescopic driving member 36 and the rotary driving member 31 are already existing mature technologies and do not belong to the improvement points of the present application, so they will not be described in detail.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
