[0001] This utility model relates to the field of lamp lens angle adjustment technology, and in particular to an adjustable lamp lens angle device. Background Technology

[0002] In the field of lighting, the adjustment of the lens angle of lighting fixtures is of great significance. Its functions are mainly reflected in many aspects: precisely controlling the illumination range, such as focusing on goods in commercial stores and locking the performance area in stage lighting; improving the uniformity of illumination, ensuring uniform lighting in classrooms and offices; and reducing glare problems, ensuring road driving safety.

[0003] Different scenarios have vastly different lighting needs, highlighting the necessity of adjusting the lens angle. In indoor environments, areas such as living rooms and bedrooms have diverse functions, and different activities require different lighting, which fixed-angle luminaires cannot meet. Outdoor scenarios are even more complex; road lighting needs to adapt to road conditions to ensure safety, and landscape lighting needs to showcase architectural features from multiple perspectives, making it difficult for fixed-angle luminaires to achieve the desired effect. Currently, there are many luminaires on the market with fixed lens angles that cannot flexibly adapt to changes in scenarios. Therefore, this application proposes a lighting fixture lens angle adjustable device. Utility Model Content

[0004] The main objective of this invention is to provide an adjustable lens angle device for lighting fixtures, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable lens angle device for a lighting fixture includes a movable lens carrier, which is fixedly installed at the lower end of the fixture body. The fixture lens body is fixedly installed inside the movable lens carrier. The movable lens carrier consists of a lens mounting base tube and a sealed corrugated hose. The sealed corrugated hose is fixedly installed at the upper end of the lens mounting base tube. A universal bending positioning assembly is fixedly installed on the outer wall of the fixture body and the lens mounting base tube. The universal bending positioning assembly consists of a rubber protective hose, a spiral copper wire, a connecting base plate, and a fixing base plate. The spiral copper wire is located inside the rubber protective hose. There are two connecting base plates, which are respectively installed at the upper and lower ends of the rubber protective hose and the spiral copper wire. There are two fixing base plates, which are respectively fixedly installed at one end of the two connecting base plates.

[0007] Preferably, a plurality of lamp mounting and fixing components are fixedly installed on the outer wall of the lamp body, and the plurality of lamp mounting and fixing components are arranged in a ring.

[0008] Preferably, the lamp lens body is fixedly mounted on the inner wall of the lens mounting base tube on the movable lens carrier.

[0009] Preferably, the sealed corrugated flexible tube on the movable lens carrier is fixedly installed at the lower end of the lamp body, and several anti-slip protrusions are fixedly installed in a ring on the outer wall of the lens mounting base tube.

[0010] Preferably, the two fixed base plates on the universal bending positioning assembly are respectively fixedly installed on the outer wall of the lamp body and the lens mounting base tube, and the connecting base plate is fixedly connected to the rubber protective hose and the spiral copper wire.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By setting up a lens angle adjustment device consisting of a movable lens carrier and a universal bending positioning component, when it is necessary to adjust the angle of the lamp lens body, the universal bending positioning component can be manually operated. Utilizing the bendable characteristics of the spiral copper wire, combined with the flexibility of the rubber protective hose, the angle of the movable lens carrier can be easily changed, thereby driving the lamp lens body to rotate to the required angle. This allows for flexible adjustment of the illumination angle, meeting the requirements for illumination range and uniformity in different scenarios. The sealed corrugated hose not only connects the lamp body and the lens mounting base tube, but also prevents dust, moisture, etc., from entering the lamp to a certain extent, protecting the optical components and electrical components of the lamp.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an adjustable lens angle device for a lighting fixture includes a movable lens carrier 3, which is fixedly installed at the lower end of the fixture body 1. The fixture lens body 2 is fixedly installed inside the movable lens carrier 3. The movable lens carrier 3 consists of a lens mounting base tube 6 and a sealed connecting corrugated hose 8. The sealed connecting corrugated hose 8 is fixedly installed at the upper end of the lens mounting base tube 6. A universal bending positioning assembly 4 is fixedly installed on the outer wall of the fixture body 1 and the lens mounting base tube 6. The universal bending positioning assembly 4 consists of a rubber protective hose 9, a spiral copper wire 10, a connecting base plate 11, and a fixing base plate 12. The spiral copper wire 10 is located inside the rubber protective hose 9. There are two connecting base plates 11, which are respectively installed at the upper and lower ends of the rubber protective hose 9 and the spiral copper wire 10. There are two fixing base plates 12, which are respectively fixedly installed at one end of the two connecting base plates 11. Several fixture mounting and fixing assemblies 5 are fixedly installed on the outer wall of the fixture body 1. Several lamp mounting and fixing components 5 are arranged in a ring. When using this adjustable lens angle device, the lamp body 1 is first installed in the required position using the lamp mounting and fixing components 5 arranged in a ring on the outer wall of the lamp body 1. After installation, if it is necessary to adjust the angle of the lamp lens body 2, the universal bending positioning component 4 is manually operated. Since the spiral copper wire 10 is located inside the rubber protective hose 9 and has bendable characteristics, and the rubber protective hose 9 is flexible, the angle of the movable lens carrier 3 connected to it can be changed by changing the shape of the universal bending positioning component 4. The movable lens carrier 3 consists of a lens mounting base tube 6 and a sealed corrugated hose 8. The sealed corrugated hose 8 is fixed to the lower end of the lamp body 1. The lamp lens body 2 is fixedly installed on the inner wall of the lens mounting base tube 6. When the angle of the movable lens carrier 3 is changed, the lamp lens body 2 rotates to the required angle, realizing flexible adjustment of the illumination angle.

[0020] Specifically, the lamp lens body 2 is fixedly mounted on the inner wall of the lens mounting base tube 6 on the movable lens carrier 3. The sealed connecting corrugated hose 8 on the movable lens carrier 3 is fixedly mounted on the lower end of the lamp body 1. Several anti-slip ridges 7 are fixedly mounted in a ring on the outer wall of the lens mounting base tube 6. Two fixed base plates 12 on the universal bending positioning assembly 4 are respectively fixedly mounted on the outer walls of the lamp body 1 and the lens mounting base tube 6. The connecting base plate 11 is fixedly connected to the rubber protective hose 9 and the spiral copper wire 10. During operation, the anti-slip ridges 7 distributed in a ring on the outer wall of the lens mounting base tube 6 can increase friction and facilitate manual operation to adjust the angle; the sealed connecting corrugated hose 8 and the rubber protective hose 9 are fixedly mounted on the outer wall of the lens mounting base tube 6. When connecting the lamp body 1 and the lens mounting base tube 6, sealant is used to fill the gaps to enhance the sealing effect. During production, the air pressure test method is used to test the sealing of the connection parts, and only those that pass the test can be used. The corrugated flexible hose 8 for sealing connection is made of silicone rubber, which has excellent high temperature resistance, strong anti-aging ability, good flexibility and resilience, and can adapt to the bending and deformation of the movable lens carrier 3. It is not easily damaged even with frequent bending, ensuring smooth angle adjustment. The spiral copper wire 10 is made of oxygen-free copper with a copper content of not less than 99.95%, which is made by cold drawing process and needs to undergo repeated bending tests to ensure good fatigue resistance and ensure long-term flexible adjustment of the angle of the lamp lens body 2. When working, the light emitted by the lamp beads in the lamp body 1 is directly directed to the lamp lens body 2. The working principle of the lamp lens body 2 is based on optical refraction. It adopts a special optical design that can change the propagation direction of the light emitted by the lamp beads. When the light passes through the lamp lens body 2, it is refracted through its curved surface, making the originally divergent light more concentrated and uniform.

[0021] Finally, by setting up a lens angle adjustment device consisting of a movable lens carrier 3 and a universal bending positioning component 4, when it is necessary to adjust the angle of the lamp lens body 2, the universal bending positioning component 4 can be manually operated. Utilizing the bendable characteristics of the spiral copper wire 10, combined with the flexibility of the rubber protective hose 9, the angle of the movable lens carrier 3 can be easily changed, thereby driving the lamp lens body 2 to rotate to the required angle, realizing flexible adjustment of the illumination angle and meeting the requirements for illumination range and uniformity in different scenarios. The sealed corrugated hose 8 not only serves to connect the lamp body 1 and the lens mounting base tube 6, but also prevents dust, moisture, etc. from entering the lamp to a certain extent, protecting the optical components and electrical components of the lamp.

[0022] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
