Examples
As shown in fig. 1-4, the lighting device provided in this embodiment includes a lighting component, a light path channel 20, a first driving component and a second driving component, where the lighting component is connected to a light inlet end of the light path channel 20, light received by the lighting component can be transmitted to the light path channel 20, the first driving component can drive the lighting component to rotate around a first horizontal direction, the second driving component can drive the lighting component to swing around a second horizontal direction, and the second horizontal direction forms an angle with the first horizontal direction.
In particular, the lighting device may be mounted on the fixed wall panel 40 when in use, to ensure the mounting smoothness of the lighting device. The light path channel 20 is a light transmission channel. Taking the example of light being introduced into an underground building, the light path channel 20 is fixedly installed on the fixed wall plate 40, and passes through the fixed wall plate 40 to be communicated with the channel for light transmission inside the building, so that the light is transmitted to the underground building. The light path 20 may be a cylindrical structure, a rectangular parallelepiped structure, or a triangular prism structure, as long as the light can be transmitted. However, in either configuration, the optical path 20 has a center line of revolution. When the light path channel 20 has a cylindrical structure, the rotation center line of the light path channel 20 is the axis thereof. In the following embodiments, the light path channel 20 is exemplified as 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 points of the lighting component and the light path channel 20.
The lighting component is arranged at the light inlet end of the light path channel 20, and is used for acquiring light rays, reflecting the light rays into the light path channel 20 and conveying the light rays along the light path channel 20. The first driving component is used for driving the lighting component to rotate around the axis of the light path channel 20, and the second driving component is used for driving the lighting component to swing around the connecting point of the lighting component and the light path channel 20. Wherein, with fixed wallboard 40 vertical placement, then light path passageway 20 perpendicular to fixed wallboard 40 sets up, and light path passageway 20 level sets up promptly, and then second drive assembly drive daylighting subassembly is around the horizontal rectilinear motion that daylighting subassembly and light path passageway 20 tie point are constituteed. As shown in fig. 2, the extending direction of the light path channel 20 is a horizontal left-right direction, namely a first horizontal direction, and a horizontal straight line formed by connecting points is a direction extending perpendicular to the drawing plane, namely a second horizontal direction, and the second driving component drives the lighting component to swing left and right around the horizontal straight line.
According to the lighting device, through the combination of two movements applied to the lighting component, the use flexibility of the lighting component is improved, the lighting component can make adaptive movements according to the irradiation angle of the sun, and further the lighting component can always face the sun so as to gather more sun lights and make the sun lights gather into light beams, so that the light beams are convenient to convey along the light path channel 20, meanwhile, the lighting component can face the sun lights so as to absorb more solar energy, and the utilization rate of the solar energy is increased.
With continued reference to fig. 1-4, the lighting assembly preferably includes a mounting frame 11, a reflective surface 12 rotatably mounted on the mounting frame 11, and a speed reducing mechanism 37 connected between the mounting frame 11 and the reflective surface 12, wherein the mounting frame 11 is connected to the light 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, the reflective surface 12 can reflect received light to the light path channel 20, the reflective surface 12 can synchronously rotate along with the mounting frame 11, and meanwhile, the swinging of the mounting frame 11 can drive the reflective surface 12 to swing through the speed reducing mechanism 37.
In particular, the mounting 11 is used to ensure good smoothness of the assembly that reflects light. The power output ends of the first driving assembly and the second driving assembly are both applied to the mounting frame 11, and then the mounting frame 11 is driven to rotate around the first horizontal direction through the first driving assembly, and the mounting frame 11 is driven to swing left and right around the second horizontal direction through the second driving assembly, so that two movements of the lighting assembly are realized. The reflecting surface 12 is a component for reflecting light to enter the light path channel 20, and the reflecting surface 12 is arranged at the light inlet end of the light path channel 20 and is rotationally connected with the mounting frame 11. Meanwhile, a speed reducing mechanism 37 is provided between the reflecting surface 12 and the mount 11. When the second driving assembly drives the mounting frame 11 to swing left and right around the second horizontal direction, the mounting frame 11 transmits the swing motion to the reflecting surface 12 through the speed reducing mechanism 37, and further drives the reflecting surface 12 to swing. However, because the speed reducing mechanism 37 is disposed between the mounting frame 11 and the reflecting surface 12, the swing amplitude of the mounting frame 11 is larger than that of the reflecting surface 12, so as to fine-tune the angle of the reflecting surface 12 relative to the light path channel 20 when the reflecting surface 12 moves along with sunlight, so that the reflection center point of the reflecting surface 12 can be always located on the axis of the light path channel 20.
With continued reference to fig. 3-5, preferably, the lighting assembly further includes a first converging surface 13 and a second converging surface 14, where the first converging surface 13 and the second converging surface 14 are both fixedly disposed on 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 and the second central axis are coaxially disposed, and the first converging surface 13, the second converging surface 14 and the reflecting surface 12 sequentially form a reflection light path. The light reflected by the reflecting surface 12 is parallel to the channel extending direction of the optical path channel 20.
Specifically, the first converging surface 13 and the second converging surface 14 are both used for reflecting light, and the first converging surface 13 and the second converging surface 14 are fixedly arranged on the mounting frame 11, so that the movement of the mounting frame 11 can drive the first converging surface 13 and the second converging surface 14 to synchronously move. The first converging surface 13 is configured to receive light irradiated by sunlight, and reflect the received light onto the second converging surface 14, and the second converging surface 14 is configured to reflect the light onto the reflecting surface 12, and further reflect the light into the light path channel 20 through the reflecting surface 12. The rotation of the first convergence surface 13 rotates along with the irradiation direction of the sunlight, which aims to make the first convergence surface 13 always face the sun, and the sunlight is directly incident into the first convergence surface 13, that is, the direction of the sunlight incident on the first convergence surface 13 is the same as the direction of the first central axis of the first convergence surface 13, so as to obtain the solar energy to the maximum extent and increase the utilization rate of the solar energy.
With continued reference to fig. 3-5, it is preferable that the first converging surface 13 is concave and has a converging function, the second converging surface 14 is convex, 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 that 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 the light beam to the reflecting surface 12, and the reflecting surface 12 is an inclined surface.
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, so that the light incident into the first converging surface 13 is ensured to be parallel to the light exiting from the second converging surface 14. If the light is vertically incident on the first convergence surface 13, the light should also be vertically emitted from the second convergence surface 14.
When the first central axis and the second central axis are in the vertical direction, the plumb lines of the first central axis, the second central axis and the reflection center point of the reflection surface 12 are positioned on the same straight line, and the reflection center point of the reflection surface 12 is positioned on the axis of the light path channel 20, so that the light can be reflected to the light path channel 20 to the greatest extent, and the utilization rate of solar energy is increased.
With continued reference to fig. 3-5, in actual use, the first driving assembly and the second driving assembly drive the mounting frame 11 to move, so that the first collecting surface 13 can face against sunlight. Taking the example that the sunlight vertically enters the first convergence surface 13, the first convergence surface 13 receives the vertically incident light and reflects the vertically incident light to the second convergence surface 14, the second convergence surface 14 can reflect the received light to the reflecting surface 12 in a direction parallel to the second central axis, and all the reflected light is parallel, that is, the light incident to the reflecting surface 12 is in the vertical direction. The reflection center point of the reflection surface 12 is located on the axis of the optical path channel 20, and the light incident on the reflection surface 12 is in the vertical direction, so that the light reflected from the reflection surface 12 to the optical path channel 20 is in the horizontal direction, that is, parallel to the axis of the optical path channel 20.
The bottom of the first converging surface 13 is provided with an opening, and the opening is located right below the second converging surface 14, so that the second converging surface 14 reflects the light to the reflecting surface 12.
With continued reference to fig. 1-4, the ratio of the swing angle of the mounting frame 11 to the swing angle of the reflecting surface 12 is preferably 2:1. Specifically, the speed reduction mechanism 37 provided between the mount 11 and the reflecting surface 12 is a two-stage speed reduction mechanism, and the swinging angle of the reflecting surface 12 is obtained by decelerating the swinging angle of the mount 11 twice. Moreover, no matter how the reflecting surface 12 swings following the mount 11, it is required that the reflecting center point of the reflecting surface 12 is located on the axis of the optical path channel 20, and the light reflected into the optical path channel 20 through the reflecting surface 12 is parallel to the axis of the optical path channel 20. If the optical path channel 20 is disposed horizontally, the light emitted from the reflecting surface 12 is in a horizontal state. The light incident on the first collecting surface 13 is a light normal to the sunlight.
1-4, In actual use, the speed reducing mechanism 37 includes a rotating shaft 371, a first pinion 372, a first large gear 373, a second pinion 374 and a second large gear 375, the reflecting surface 12 is fixedly connected with the rotating shaft 371, the rotating shaft 371 is rotatably connected with the drum 32, the first pinion 372 is fixedly connected with the mounting frame 11 and is rotatably connected with the rotating shaft 371, the first large gear 373 is meshed with the first pinion 372, the second pinion 374 is coaxially rotated with the first large gear 373, and the second large gear 375 is fixedly arranged on the rotating shaft 371 and is meshed with the second pinion 374.
Specifically, the first pinion 372 and the second bull gear 375 are coaxially disposed, and both are disposed on the rotating shaft 371, the first pinion 372 is rotatably connected to the rotating shaft 371, and the second bull gear 375 is fixedly connected to the rotating shaft 371. The first pinion 372 is fixedly connected with the mounting frame 11 and further synchronously and uniformly swings along with the mounting frame 11, and the rotating shaft 371 is fixedly arranged on the reflecting surface 12 and further can drive the reflecting surface 12 to swing around the axis of the rotating shaft 371 through rotation of the rotating shaft 371. The first large gear 373 and the second small gear 374 are coaxially arranged, 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 synchronously rotate. The first pinion 372 is meshed with the first large gear 373, the second pinion 374 is meshed with the second large gear 375, the second large gear 375 is fixedly connected with the rotating shaft 371, and 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.
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 smaller than the number of teeth of the first bull gear 373, and the first pinion 372 is meshed with the first bull gear 373, so that the rotation speed of the first bull gear 373 is smaller than that of the first pinion 372, and the first reduction of the swinging angle of the mounting frame 11 is achieved. The first large gear 373 drives the second small gear 374 to synchronously rotate, so that the rotation speeds of the first large gear and the second small gear are the same. The number of teeth of the second pinion 374 is smaller than the number of teeth of the second large gear 375, and the two are engaged, so that the rotation speed of the second large gear 375 is smaller than the rotation speed of the second pinion 374, as a second deceleration of the swing angle of the mount 11. The rotation angle of the reflecting surface 12 is half of the rotation angle of the mounting frame 11 through twice deceleration, so that the reflecting surface 12 can reflect light rays into the light path channel 20 in the direction parallel to the axis of the light path channel 20 while guaranteeing that the reflecting surface 12 swings along with the mounting frame 11, the probability that the light rays are reflected onto the inner wall of the light path channel 20 in the reflecting process is reduced, and the utilization rate of the received light rays is increased.
With continued reference to fig. 1-3, the second drive assembly optionally includes a telescopic drive member 36 and a connecting plate 35, the telescopic drive member 36 being hinged to the connecting plate 35, and a power output end of the telescopic drive member 36 being hinged to the mounting frame 11, the telescopic drive member 36 being capable of driving the mounting frame 11 to oscillate about a connection point with the drum 32.
