Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0034] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "top surface", "bottom surface", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the indicated positions or elements must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0035] Such as Figures 1 - 8As shown in the figure, the optical system disclosed by the present utility model includes a flexible optical fiber 100, a collimating device, and an optical adhesive layer 700. The collimating device is used for condensing light and transmitting the light to the flexible optical fiber 100, and the optical adhesive layer 700 is used for bonding the collimating device and the flexible optical fiber 100. Specifically, the above-mentioned optical adhesive layer 700 is used for optically bonding the collimating device and the flexible optical fiber 100, and the optical adhesive layer 700 can be formed by a UV curable adhesive or other optical adhesives. By arranging the optical adhesive layer 700, the design of the optical system is optimized, and the optical loss caused by multiple optical path transmission interfaces is reduced, thereby optimizing the lighting effect of the lamp. When the optical system provided by the present utility model is used, the optical adhesive layer 700 bonds the collimating device and the flexible optical fiber 100, which can effectively reduce the optical loss caused by light passing through multiple transmission interfaces, thereby improving the optical efficiency of the optical system and optimizing the lighting effect of the lamp.

[0036] To optimize the above technical solution, the collimating device includes at least one collimating condenser 200. Specifically, one collimating condenser 200 can be arranged corresponding to one flexible optical fiber 100. When in use, the collimating device can include multiple collimating condensers 200, and multiple flexible optical fibers 100 are arranged in parallel or at an angle of 0 to 180° to form various lighting effects. Specifically, the collimating condenser 200 is an optical component, and its material includes but is not limited to glass, optical plastics, etc., which will not be elaborated herein.

[0037] Furthermore, the optical system further includes a control system, so that the operator can control the opening and closing of single or multiple collimating condensers 200, and the lighting or extinguishing of single or multiple flexible optical fibers 100 according to the lighting requirements, so as to optimize the lighting effect and use flexibility of the lamp.

[0038] To optimize the above technical solution, the optical system further includes a transparent bracket 300, and the transparent bracket 300 is connected with at least one bundle of flexible optical fibers 100. It should be noted that in the prior art, the installation of the flexible optical fiber 100 is to set multiple spaced buckles on the bracket to form multiple points for positioning the flexible optical fiber 100. However, both the bracket itself and the buckles will block the light of the flexible optical fiber 100, making it lose the advantage of emitting light throughout the body. The conventional improvement idea is to reduce the volume of the bracket, but the lighting effect cannot be significantly improved. Therefore, setting the bracket for supporting the flexible optical fiber 100 as a transparent bracket 300 can display the technical advantage of the flexible optical fiber 100 emitting light evenly and throughout the body, creating a visual sense of spatial suspension of the optical system when it is not lit or lit, thereby optimizing the lighting effect of the lamp and enhancing the delicacy of the product. Further, one transparent bracket 300 can be simultaneously connected with one or more bundles of flexible optical fibers 100, and one or more collimating condensers 200, so that the lighting area of the lamp is the overall structure while ensuring the lighting effect.

[0039] To optimize the above technical solution, the transparent bracket 300 is provided with a clamping groove 301. The notch of the clamping groove 301 is smaller than the diameter of the flexible optical fiber 100, and the distance between the bottom of the clamping groove 301 and the notch is greater than the radius of the flexible optical fiber 100. The clamping groove 301 is used for clamping the flexible optical fiber 100. Specifically, the clamping groove 301 is arranged along the axial direction of the flexible optical fiber 100. When the clamping groove 301 is clamped with the flexible optical fiber 100, at least one-half of the surface of the flexible optical fiber 100 is clamped inside the clamping groove 301 to strengthen the fixing effect on the flexible optical fiber 100. At the same time, since the bracket is the transparent bracket 300, it will not block the flexible optical fiber 100, so that while the flexible optical fiber 100 is fixed, the overall luminous effect of the flexible optical fiber 100 in the lit state is ensured, and the lighting effect of the lamp is optimized. It should be noted that in the prior art, the fixing method for the flexible optical fiber 100 is multi-point bundling and fixing by multiple buckles. The present invention utilizes the elastic characteristic of the flexible optical fiber 100 to squeeze the flexible optical fiber 100 into the clamping groove 301 and complete the abutment in the clamping groove 301 by its own elasticity, thus having the advantages of eliminating the buckle structure, reducing production costs, improving the lighting effect, and saving installation steps.

[0040] To optimize the above technical solution, the optical system further includes a light source board 400. At least one LED particle 401 is arranged on the first side of the light source board 400, and the LED particle 401 corresponds to the first end of the collimating condenser 200. It should be noted that in the prior art, a laser light source is often used as the light source of the exterior decoration lamp, but its cost is relatively high. At the same time, although the cost of the LED light source is low, the brightness formed by it is also low. Therefore, the LED light source is often used as the light source of the interior decoration lamp and cannot be used as the light source of the exterior decoration lamp. To solve the above problems, the present invention uses an optical adhesive layer 700 to bond the collimating condenser 200 and the flexible optical fiber 100, thereby improving the fiber efficiency of the optical system and realizing the application of the low-cost LED light source as the exterior decoration lamp. Specifically, the number of LED particles 401 is adapted to the number of collimating condensers 200 and the number of flexible optical fibers 100, and the light source board 400 is electrically connected to the control system of the optical system, so that the operator can control the turning on and off of single or multiple LED light sources according to the lighting requirements to realize the lighting or extinguishing of single or multiple flexible optical fibers 100, thereby optimizing the lighting effect and use flexibility of the lamp.

[0041] To optimize the above technical solution, a groove 201 is provided at the second end of the collimating concentrator 200. The groove 201 is used to clamp the end of the flexible optical fiber 100, and the optical adhesive layer 700 is arranged at the bottom and / or the inner wall of the groove 201. During use, the flexible optical fiber 100 is inserted into the groove 201 and contacts the optical adhesive on its bottom or inner wall, and an optical adhesive layer 700 is formed between the flexible optical fiber 100 and the groove 201, thereby forming a double-layer fixation between the flexible optical fiber 100 and the collimating concentrator 200 to improve the overall stability of the optical system. Specifically, the diameter of the groove 201 may be equal to or slightly smaller than the diameter of the flexible optical fiber 100, so that the flexible optical fiber 100 remains in a clamped state after being pressed into the groove 201, thereby further improving the fixation effect of the flexible optical fiber 100.

[0042] To optimize the above technical solution, the optical system further includes a collimating bracket 500. The first side of the collimating bracket 500 is connected to the light source board 400, and a through hole 501 is provided on its second side. The through hole 501 is used to clamp the outer peripheral surface of the flexible optical fiber 100; and / or, a step 502 is provided inside the collimating bracket 500. The step 502 is used to clamp the collimating concentrator 200. Specifically, a clamping structure 202 perpendicular to the light transmission path is arranged on the outer surface of the collimating concentrator 200. This clamping structure 202 is clamped with the above step 502 to limit the movement of the collimating concentrator 200. Specifically, the wall of the groove 201 of the collimating concentrator 200 abuts against the wall of the through hole 501, so that the flexible optical fiber 100 directly inserts into the groove 201 after passing through the through hole 501. During use, the end of the flexible optical fiber 100 passes through the through hole 501 of the collimating bracket 500 and enters the groove 201 of the collimating concentrator 200, and an optical adhesive layer 700 is formed in the groove 201 to complete the fixation of the flexible optical fiber 100 to the collimating bracket 500 and the fixation of the flexible optical fiber 100 to the collimating concentrator 200. Further, a plurality of through holes 501 can be provided on the collimating bracket 500 according to the number and arrangement position of the flexible optical fibers 100 to meet the diversified lighting design of the lamp.

[0043] Further, the collimating bracket 500 is fixedly connected to the light source board 400 by screws to form a fixation.

[0044] To optimize the above technical solution, the optical system further includes a radiator 600, which is arranged on the second side of the light source board 400 and connected to the light source board 400. Specifically, the operator can select to configure or not configure the radiator 600 according to the number, diameter, etc. of the flexible optical fibers 100. Further, the radiator 600 can be bolted to the light source board 400 and / or inserted into the collimating bracket 500, that is, one of the collimating bracket 500 or the radiator 600 is provided with an insertion hole 601, and the other is provided with a protrusion 602. Matching the insertion hole 601 with the protrusion 602 can improve the stability and safety of the overall structure of the optical system, thereby ensuring the operating efficiency of the optical system.

[0045] To optimize the above technical solution, the transparent bracket 300 is a curved bracket; and / or, the transparent bracket 300 is a curved surface bracket. Specifically, the operator can change the appearance of the transparent bracket 300 according to the usage requirements and lighting requirements. For example, it can be set in the shape of a flowing water shape, a bent shape, etc., and the curvature of the side where the groove 201 is opened on the transparent bracket 300 can also be changed. For example, it can be set as a concave curved surface or a convex curved surface, so as to optimize the lighting effect and usage flexibility of the lamp.
