In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified.

[0028] In order to further illustrate the principles and structures of the present application, the preferred embodiments of the present application will be described in detail in conjunction with the drawings.

[0029] Please refer to Figures 1 to 8 The present application provides a solar light guide lamp, which comprises a light collecting part arranged outdoors and a lighting part arranged indoors. The light collecting part comprises a first shell 1. The top of the first shell 1 is an light inlet 121. The bottom of the first shell 1 is provided with a fixing seat 14. The first shell 1 can be placed on the ground or installed on a mounting rack 8 through the fixing seat 14. Of course, the fixing seat 14 is not indispensable. The first shell 1 can also be placed on the ground or installed on the mounting rack 8 through the bottom surface in contact with the ground.

[0030] The first shell 1 is a hollow structure. Its shape can be a square or a cylindrical body with arc-shaped sides. As a preferred scheme, the first shell 1 is a square. When a plurality of first shells 1 are arranged in an array, the outer side of the square first shell 1 can be in close contact with the outer side of another square first shell 1, which can improve the utilization of space.

[0031] The first housing 1 of the aforementioned cuboid has a square bottom plate 11 and a top plate 12 arranged opposite to each other. The top plate 12 has a light inlet 121 that passes through its center. Side plates 13 are vertically arranged around the periphery of the bottom plate 11. The bottom plate 11, the top plate 12 and the side plates 13 together form a light-collecting chamber 16. Furthermore, the bottom plate 11 is also provided with vertical columns 15. There are at least four columns 15, which are distributed at the four corners of the first housing 1. The columns 15 can enhance the structure of the first housing 1, so that the light-collecting part can withstand the test of the outdoor environment.

[0032] The aforementioned light-collecting chamber 16 is connected to the light inlet 121, allowing light to enter the light-collecting chamber 16 through the light inlet 121. A first lens 2, capable of converging sunlight, is provided on the side of the light-collecting chamber 16 near the light inlet 121. The first lens 2 can be a common convex lens, or, to achieve higher light transmission efficiency, a Fresnel lens. A light guide tube 3 is also connected between the aforementioned light-collecting section and the lighting section. The light guide tube 3 has an input end and an output end. The input end of the light guide tube 3 enters the light-collecting chamber 16 and corresponds to the first lens 2, while the output end of the light guide tube 3 enters the room and connects to the lighting section. After passing through the first lens 2 and the light guide tube 3 in sequence, sunlight is emitted from the lighting section, thereby transmitting sunlight into the room and achieving the lighting effect.

[0033] The first housing 1 can also be fixedly fitted with a protective glass a17 at one end with a light inlet 121. The protective glass a17 is preferably made of high-strength acrylic sheet with high light transmittance. The protective glass a17 isolates the light-transmitting chamber 16 from the outside world and has the function of pressure resistance and dust prevention.

[0034] The light guide tube 3 described above is made of a material similar to or equivalent to optical fiber, and has good light transmission efficiency. The light guide tube 3 is not limited to a "tube" and can also be specifically an optical fiber. As a preferred embodiment of the light guide tube 3, a cladding layer 31 can also be provided on the surface of the light guide tube 3. The cladding layer 31 can be a light reflective film or tin foil with high light reflectivity to prevent some light from being lost from the side of the light guide tube 3 during the transmission of light, thereby giving the light guide tube 3 higher transmission efficiency.

[0035] like Figure 1 , 4As shown, the lighting unit includes a second housing 4, which has a light outlet 41. The structure of the second housing 4 is only slightly different from that of the first housing 1. The difference is that the light outlet 41 of the second housing 4 is located on the bottom plate 11 of the second housing 4, while the light inlet 121 of the first housing 1 is located on the top plate 12 of the first housing 1. Therefore, the remaining components of the second housing 4 will not be described in detail here. A first chamber 42 is formed inside the second housing 4. The first chamber 42 is connected to the light outlet 41. The output end of the light guide tube 3 passes through the top plate 12 of the second housing 4 and enters the first chamber 42. A protective glass b43 is provided at the end of the second housing 4 with the light outlet 41, which also has the function of dustproof and pressure resistant.

[0036] Preferably, the inner wall of the first chamber 42 can be made of a highly reflective material to reduce light loss in the first chamber 42. Alternatively, a highly reflective material layer can be covered on the inner wall surface of the first chamber 42 to achieve the same or similar effect.

[0037] The aforementioned lighting section is equipped with a light adjustment mechanism, which can adjust the angle at which the light is emitted from the lighting section. Under the adjustment of the mechanism, the light can be emitted from the lighting section in parallel, divergent, or convergent directions. Parallel light has good brightness and can also illuminate a certain area; divergent light can provide illumination for a larger area; and convergent light has higher brightness and is suitable for illuminating specific items, such as exhibits and indoor plants. Higher brightness is more conducive to the display of exhibits and the growth of plants. With the action of the light adjustment mechanism, the light guide can be used in a variety of scenarios and has a wide range of applications.

[0038] The aforementioned light adjustment mechanism includes a second lens 5 and a moving component 6. The second lens 5 is disposed in the first chamber 42. The moving component 6 can cause relative movement between the second lens 5 and the output end of the light guide tube 3. When adjusting the light angle, the user can adjust the distance between the second lens 5 and the output end of the light guide tube 3 along the axis of the first chamber 42 (i.e., change the angle at which the light emitted from the output end of the light guide tube 3 is directed toward the second lens 5) to achieve the purpose of adjusting the light emission angle.

[0039] The second lens 5 can be a regular lens, but to improve the utilization rate of light, the second lens 5 is preferably a Fresnel lens.

[0040] Figures 4-5In another embodiment of the adjustment mechanism, as shown in the figure, the output end of the light guide tube 3 is fixed to the upper part of the first chamber 42. A lens seat 51 is also slidably disposed in the first chamber 42. The lens seat 51 can slide along the axial direction of the first chamber 42. An installation port is opened in the center of the lens seat 51. The second lens 5 is fixedly disposed in the installation port. The light emitted from the output end of the light guide tube 3 passes through the installation port and the second lens 5 and is emitted outward from the light outlet 41. The moving component 6 is connected to the lens seat 51. During adjustment, the moving component 6 drives the lens seat 51 to move. The lens seat 51 drives the second lens 5 to move along the axial direction of the first chamber 42 closer to or away from the output end of the light guide tube 3, thereby adjusting the emission angle of the light.

[0041] In order to enable the moving component 6 to drive the lens holder 51 to move within the first chamber 42, the moving component 6 includes a screw 61, a contact part 62 and a driving component. One end of the screw 61 is connected to the lens holder 51, the contact part 62 is disposed on the illumination part and engages with the screw 61, and the driving component is used to drive the contact part 62 and the screw 61 to rotate relative to each other.

[0042] The connection between the screw 61 and the lens holder 51 can be either a fixed connection at one end to the lens holder 51, or a bearing can be provided on the lens holder 51, with one end of the screw 61 rotatably connected to the lens holder 51 via the bearing. When one end of the screw 61 is fixedly connected to the lens holder 51, the contact part 62 engaging with it is rotatably disposed within the first chamber 42. The driving component is connected to the contact part 62, and the driving component drives the contact part 62 to rotate, which can drive the screw 61 to move within the first chamber 42, thereby driving the lens holder 51 and the second lens 5 to move axially within the first chamber 42. When one end of the screw 61 is rotatably connected to the lens holder 51, the contact part 62 engaging with it is fixedly disposed within the first chamber 42. The driving component is connected to the screw 61, and the driving component drives the screw 61 to rotate. With the cooperation of the contact part 62, the screw 61 can move within the first chamber 42, thereby causing the lens holder 51 and the second lens 5 to move axially within the first chamber 42.

[0043] like Figures 4-5 As shown, the aforementioned driving component is a control handle 63 rotatably disposed in the second housing 4. The control handle 63 has a connecting end and a control end. When the contact part 62 is rotated, the connecting end extends into the first chamber 42 and connects with the contact part 62. When the contact part 62 is fixed, the connecting end is fixedly connected to the screw 61. The control end is disposed outside the second housing 4 for user convenience.

[0044] As one embodiment of the adjustment mechanism, the second lens 5 is fixedly disposed in the first chamber 42, the output end of the light guide tube 3 can move along its axial direction in the first chamber 42, and the moving component 6 is disposed in the first chamber 42 and connected to the output end of the light guide tube 3. When adjusting the light, the moving component 6 can control the output end of the light guide tube 3 to move closer to or further away from the second lens 5 along the axial direction of the first chamber 42, thereby adjusting the emission angle of the light.

[0045] To enable the moving component 6 to control the movement of the output end of the light guide tube 3 within the first chamber 42, the moving component 6 includes a screw 61 (not shown in the figure) disposed within the first chamber 42 and rotatable about its own axis, a connecting block (not shown in the figure) threadedly connected to the screw 61, and a guide component (not shown in the figure) disposed along the axial direction of the first chamber 42 and close to the connecting block. The axis of the screw 61 is parallel to the axis of the first chamber 42. The connecting block is slidably connected to the guide mechanism. The guide component provides guidance for the connecting block. The guide component can be a guide rod or a guide groove. Under the limiting action of the guide component, the rotation of the screw 61 can drive the connecting block to move axially in the first chamber 42. The output end of the light guide tube 3 is fixedly connected to the connecting block. When the connecting block moves, the output end of the light guide tube 3 can move axially along the first chamber 42.

[0046] Figure 2 , 3 As an embodiment of the present invention, 8 also includes a light filtering mechanism 7, which is disposed between the output end of the first lens 2 and the light guide tube 3. The light filtering mechanism 7 can selectively filter infrared light, ultraviolet light and visible light in sunlight. In the agricultural field, it can be reasonably matched with plant growth light that can be utilized by plants, so that plants can grow better and faster.

[0047] As a first embodiment of the light filtering mechanism 7, such as Figures 2-3 As shown, the light filtering mechanism 7 includes a dichroic reflector 71 disposed in the light converging area of ​​the first lens 2, a light reflector 72 disposed in the reflection direction of the dichroic reflector 71, and the input end of the light guide tube 3 disposed below the dichroic reflector 71. Light that does not need to be filtered can pass through the dichroic reflector 71 and be directed to the input end of the light guide tube 3. Light that needs to be filtered, such as ultraviolet light and infrared light, is reflected by the dichroic reflector 71 to the light reflector 72. Under the action of the light reflector 72, the light that needs to be filtered is reflected from the light inlet 121 of the first housing 1 out of the light-collecting chamber 16. The advantage of using the reflection method is that the heat generated by useless harmful light can be reflected out of the light-collecting chamber 16, avoiding the accumulation of heat in the light-collecting chamber 16 and preventing the light-collecting chamber 16 from overheating and causing unsafe factors.

[0048] As a second embodiment of the light filtering mechanism 7, the light filtering mechanism 7 includes a dichroic reflector 71 disposed in the light converging area of ​​the first lens 2, an extinction device (not shown in the figure) disposed in the light reflection direction of the dichroic reflector 71, and the input end of the light guide tube 3 disposed below the dichroic reflector 71. Light that does not need to be filtered can pass through the dichroic reflector 71 and be directed to the input end of the light guide tube 3; light that needs to be filtered, such as ultraviolet light and infrared light, is reflected by the dichroic reflector 71 to the extinction device, which absorbs the useless harmful light, avoids the accumulation of heat in the light-collecting chamber 16, and prevents the light-collecting chamber 16 from overheating and causing unsafe factors.

[0049] As a third embodiment of the light filtering mechanism 7, the light filtering mechanism 7 is one or more light filtering films (not shown in the figure) disposed between the first lens 2 and the input end of the light guide tube 3. The light filtering film can achieve the function of light filtering, but it is easy to accumulate heat in the light collection chamber 16. Therefore, the first embodiment or the second embodiment of the light filtering mechanism 7 is preferred in this application.

[0050] Preferably, the light filtering mechanisms 7 described above are all detachably installed in the light-collecting chamber 16. Users can replace the dichroic reflector 71 or the light filtering film that filters specific light wavelengths according to their needs, so that the light guide can be used in a variety of scenarios.

[0051] Preferably, it also includes an outdoor mounting frame 8. The number of light-collecting units can be one or more. The mounting frame 8 and the light-collecting units are provided with corresponding and compatible flange interfaces. Multiple light-collecting units can be arrayed and spliced ​​on the mounting frame 8. The mounting frame 8 can fix the light-collecting units to prevent them from tipping over and enhance the stability of the lighting.

[0052] Furthermore, it also includes a solar tracker or equatorial mount. The mounting bracket 8 can be installed on the solar tracker or equatorial mount and the light inlet 121 of the light-collecting part is aligned with the sun. As time goes by, the mounting bracket 8 rotates under the drive of the solar tracker or equatorial mount so that the light-collecting part always faces the sun, further enhancing the stability of the lighting.

[0053] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
