[0048] The present invention provides a light guide structure 100 .

[0049] Reference Figures 1 to 4 In an embodiment of the present invention, the light guide structure 100 includes a fixing assembly 10, a light source assembly 20 and a light homogenizing member 30, wherein:

[0050] The fixing assembly 10 forms a receiving space with an opening;

[0051] The light source assembly 20 is disposed in the accommodating space;

[0052] The light-distributing member 30 is connected to the fixing assembly 10 and covers the opening. The light-distributing member 30 is arranged opposite to the light source assembly 20 so that the light emitted by the light source assembly 20 is emitted from the light-distributing member 30.

[0053] It is defined that when the light emitted by the light source assembly 20 passes through the interior of the light homogenizing member 30 , the optical distance between any two light rays satisfies: 0.9L2≤L1≤1.1L2.

[0054] The conduit structure is defined as having an up-and-down direction, and the fixing assembly 10 forms a receiving space with an opening facing upward, so that the light source assembly 20 can be installed in the receiving space from the opening for easy installation. The light-distributing member 30 is connected to the fixing assembly 10 and covers the opening, thereby protecting the light source assembly 20 and preventing the light source assembly 20 from being damaged by collision with external objects. At the same time, the light-distributing member 30 is a light-guiding material such as inorganic glass or organic polymer, as well as fiber and nano-composite materials, and the fixing assembly 10 is made of opaque materials such as metal or plastic, so that the light emitted by the light source assembly 20 can only pass through the light-distributing member 30 to irradiate the external environment, so as to ensure the lighting effect of the light source assembly 20.

[0055] The light guide structure 100 of the technical solution of the present invention includes a fixed component 10, a light source component 20 and a light homogenizer 30. The light source component 20 is installed in the accommodating space through the opening of the fixed component 10, and then the light homogenizer 30 covers the opening. The light emitted by the light source component 20 passes through the light homogenizer 30 and then irradiates into the external environment, so that the light emitting surface of the light source component 20 is relatively concentrated to ensure the light emitting effect. When the light emitted by the light source component 20 passes through the inside of the light homogenizer 30, the optical distance between any two light rays satisfies 0.9L2≤L1≤1.1L2. In this way, the light homogenizer 30 is set to reduce the difference in the optical distance of the light of the light source component 20 during the propagation process, so that the color temperature of the light of the light source component 20 can still maintain a uniform color temperature after drifting through the light homogenizer 30, so that the light color effect remains consistent, so that the light output effect of the light source component 20 after passing through the light homogenizer 30 is uniform and there is no dark area shadow, thereby improving the light guiding lighting effect of the light guide structure 100.

[0056] Reference Figures 1 to 8 In one embodiment of the present application, a light-homogenizing curved surface 3211 is formed on the side of the light-homogenizing member 30 facing the light source assembly 20, and the light-homogenizing curved surface 3211 is inclined toward the inner surface of the light-homogenizing member 30. Specifically, by setting the light-homogenizing curved surface 3211, when the light of the light source assembly 20 is emitted toward the light-homogenizing member 30 and enters the interior of the light-homogenizing member 30 through the light-homogenizing curved surface 3211, the optical distance between any two light rays entering the light-homogenizing member 30 from different angles can satisfy 0.9L2≤L1≤1.1L2, that is, the difference in the optical distance of the light of the light source assembly 20 during the propagation process is effectively reduced, so that the light emitted from the light-homogenizing member 30 can still maintain a uniform color temperature, and the light output effect is relatively uniform. In addition, the light-homogenizing curved surface 3211 is a high-light anti-transmittance optical surface, that is, a high-light surface in the mold, which plays a role of high-light anti-transmittance, so that when light enters through the light-homogenizing curved surface 3211, the anti-transmittance effect of the light is guaranteed, so as to further improve the light guiding lighting effect of the light guiding structure 100.

[0057] Furthermore, the light homogenizing member 30 includes a cover portion 31 and an inserting portion 32, wherein:

[0058] The cover portion 31 is connected to the plug portion 32 , and the cover portion 31 is connected to the fixing assembly 10 and covers the opening;

[0059] The plug-in portion 32 is inserted into the accommodating space. The plug-in portion 32 has a light-distributing curved surface 3211 and a bottom surface 3212 connected to the light-distributing curved surface 3211 . The bottom surface 3212 faces the light source assembly 20 , and the bottom surface 3212 is arranged in a curved surface.

[0060] Specifically, the cover 31 and the plug-in portion 32 can be an integrated structure, which not only ensures the strength of the overall structure of the light-distributing member 30, but also saves the process of later installation and improves production efficiency. The cover 31 is arranged in a ring shape, and the plug-in portion 32 is also arranged circumferentially around one side of the cover 31, so that when the cover 31 is covered at the opening, the plug-in portion 32 is inserted into the accommodating space, so that the light of the light source assembly 20 can be irradiated to the plug-in portion 32 for light guidance. By making the bottom surface 3212 of the connector 32 connected to the light-distributing curved surface 3211 to be curved, when the light from the light source assembly 20 enters the light-distributing member 30 from the bottom surface 3212, the optical distance between any two light rays entering the light-distributing member 30 can satisfy 0.9L2≤L1≤1.1L2, which effectively reduces the difference in the optical distance of the light from the light source assembly 20 during the propagation process. In this way, the curved bottom surface 3212 further ensures that the light is more uniform after passing through the light-distributing member 30.

[0061] Furthermore, the surface of the cover body 31 facing the light source assembly 20 is concavely formed with an arc surface 311 in a direction away from the plug-in portion 32. Specifically, in order to prevent the light at the joint of the fixing assembly 10 and the cover body 31 from being blocked and causing a more obvious shadow, the surface of the cover body 31 facing the light source assembly 20 is concavely formed with an arc surface 311 in a direction away from the plug-in portion 32, so that the light passing through the arc surface 311 is refracted, thereby reducing the influence of the unsightly lighting effect caused by the joint, and further improving the light guide lighting effect of the light guide structure 100.

[0062] In one embodiment of the present application, refer to Figures 5 to 8 The plug-in portion 32 includes an insertion section 321 and a connection section 322 connected to each other, wherein:

[0063] One end of the connecting section 322 facing away from the insertion section 321 is connected to the cover body 31, and the surface of the end of the insertion section 321 facing away from the connecting section 322 is the bottom surface 3212. A light emitting gap is formed between the connecting section 322 and the curved surface 311 of the cover body 31, and the angle between the surface of the connecting section 322 facing the curved surface 311 and the curved surface 311 is an obtuse angle.

[0064] Specifically, a light emitting gap is formed between the connecting section 322 and the curved surface 311 of the cover body, and the angle between the surface of the connecting section 322 facing the curved surface 311 and the curved surface 311 is set to be an obtuse angle. The light emitting gap can prevent light from being refracted to other positions, thereby enhancing the brightness of the light-homogenizing element 30 on one side of the connecting section 322, thereby improving the lighting effect.

[0065] In one embodiment of the present application, refer to Figure 4 and Fig. 9, the light source assembly 20 includes a circuit board 21 and a display light source 22, wherein:

[0066] The circuit board 21 is connected to the fixing assembly 10 , and the display light source 22 is connected to a side of the circuit board 21 facing the light homogenizing member 30 , and is disposed opposite to the light homogenizing member 30 .

[0067] Specifically, the display light source 22 is an LED light, which is soldered to the circuit board 21. The light of the LED can be a relatively mild yellow light, so that the light emitted is relatively soft and not dazzling. The display light source 22 is arranged opposite to the light homogenizing member 30 to ensure that the light of the display light source 22 is irradiated to the light homogenizing member 30.

[0068] Furthermore, a plurality of display light sources 22 are provided, and the plurality of display light sources 22 are arranged at intervals around the circuit board 21 .

[0069] Specifically, a plurality of display light sources 22 are arranged at intervals around the circuit board 21, so that the display light sources 22 are arranged evenly at intervals, thereby eliminating glare and achieving a better light output effect, while reducing the number of light sources used and reducing product power consumption.

[0070] In one embodiment of the present application, refer to Figure 4 The fixing assembly 10 includes a support frame 11 and a cloth net 12, wherein:

[0071] The cloth net 12 is fixedly mounted on the outer surface of the support frame 11, and the support frame 11 forms a receiving space with an opening;

[0072] The bracket 11 is detachably connected to the light source assembly 20 and the light homogenizing member 30 , respectively, so that the light source assembly 20 and the light homogenizing member 30 are disposed opposite to each other.

[0073] Specifically, the cloth net 12 is elastically sleeved on the outer surface of the support frame 11, which is convenient for early installation and later maintenance and replacement. At the same time, the cloth net 12 also plays a dustproof role to prevent external dust from affecting the light source assembly 20. The support frame 11 is provided with a first connecting hole, and the light-distributing member 30 is provided with a corresponding second connecting hole corresponding to the first connecting hole. The second connecting hole and the first connecting hole are passed through the fixing member in sequence to detachably connect the light-distributing member 30 to the support frame 11. The first connecting hole and the second connecting hole can also be threaded holes, and the fixing member can be a screw. The support frame 11 is fixed to the light-distributing member 30 by screws. This fixing method is relatively simple to install and easy to disassemble, which is convenient for subsequent maintenance. Alternatively, the support frame 11 and the light-distributing member 30 can be fixed by means of a buckle or the like, which can be specifically selected according to those skilled in the art.

[0074] In one embodiment of the present application, refer to Figures 1 to 3, the light guide structure 100 further includes a decorative top cover 40, wherein:

[0075] The decorative top cover 40 is connected to the side of the light homogenizing member 30 away from the fixing assembly 10 . The surface of the light homogenizing member 30 away from the light source assembly 20 forms an appearance surface 33 . The appearance surface 33 is connected to the decorative top cover 40 in a smooth transition.

[0076] Specifically, the decorative top cover 40 can be fixed to the light-distributing member 30 by means of screws or other detachable means, so as to facilitate later maintenance and replacement. The decorative top cover 40 is made of opaque material, so that light enters the light-distributing member 30 and is emitted from the appearance surface 33. At the same time, the appearance surface 33 is connected to the decorative top cover 40 in a smooth transition to enhance the overall appearance of the light-guiding structure 100. Therefore, there is no need to set up additional appearance parts, which reduces the number of parts, reduces the manufacturing cost of plastic parts, and reduces the assembly cost. In addition, the appearance surface 33 of the light-distributing member 30 is a special optical microstructure surface, that is, the etched surface in the mold, which plays a role in softening the light, so as to further soften the overall optical effect of the light-guiding structure 100.

[0077] The present invention further proposes an intelligent lighting device, which includes a light guide structure 100.
