Description

Technical Field

[0001] This utility model belongs to the technical field of projection lamp lens assembly, specifically relating to a projection lamp lens assembly with a ring-shaped light emission effect. Background Technology

[0002] A floodlight, also known as a spotlight or spotlight, is a type of lighting fixture that produces a directional beam of light. It achieves illumination or highlighting by focusing light onto a specific area or object. The floodlight lens assembly is a key component of the floodlight system; it typically consists of multiple lenses that control the propagation and focusing of light through different shapes and curvatures. Lenses are generally made of optical glass or plastic and have the function of refracting and reflecting light, thereby changing the direction and focusing effect of the light.

[0003] The working principle of lens assemblies is primarily based on the principles of light refraction and reflection. When light enters another medium from one medium (such as from air into a lens), the direction of light propagation changes, i.e., refraction occurs. By combining lenses of different shapes and curvatures, the propagation path and focal point of light can be controlled. Existing lens assemblies have the following problems in use:

[0004] In practical applications, existing projector lens assemblies typically limit the luminous effect to solid geometric shapes, such as circles, squares, or ellipses. However, these lens assemblies still have limitations in their illumination patterns; they cannot directly create a ring-shaped luminous effect. This prevents projectors from achieving their intended effects when used to highlight the edges of display areas, create unique atmospheres, or achieve specific visual effects. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a projector lens assembly with a ring-shaped light emission effect. This lens assembly aims to solve the problem that, in practical applications, the light emission effect of existing projector lens assemblies is usually limited to solid geometric shapes, such as circles, squares, or ellipses. However, the lens assembly still has certain limitations in its illumination mode, namely, it cannot directly form a ring-shaped light emission effect. This results in the projector failing to achieve the desired effect when used to highlight the edges of display areas, create unique atmospheres, and achieve specific visual effects.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a projection lamp lens assembly with a ring-shaped light emission effect. The lens assembly includes an assembly housing, a reflector, and a lens body. The reflector is connected to the inner side of the assembly housing, and the lens body is arranged on one side of the assembly housing. A bearing seat is installed on the inner wall of the assembly housing, and a threaded rod is connected through the inside of the bearing seat. A driven bevel gear is connected to the end of the threaded rod, and the threaded rod passes through the inside of a movable block. A concave lens is connected to the side surface of the movable block, and a light-shielding coating is adhered to the inner wall of the concave lens. A drive motor is installed on the inner wall of the assembly housing, and the output end of the drive motor is connected to a driving bevel gear.

[0009] When using the lens assembly of this technical solution, the drive motor drives the threaded rod to rotate through the active bevel gear and the driven bevel gear. The rotation of the threaded rod drives the concave lens to move downward through the movable block. When the concave lens moves downward to one side of the lens body, the light cannot pass through the concave lens when it hits the surface of the light-shielding coating. The light that hits the inner wall of the concave lens will be refracted to the outside. Then the light will pass through the lens body and be emitted into the external environment, thus forming a ring-shaped light-emitting effect.

[0010] Preferably, the threaded rod forms a rotating structure between the bearing seat and the component housing. The threaded rod and the movable block are symmetrically arranged on both sides of the concave lens. The threaded rod and the movable block are connected by a thread. When the threaded rod rotates inside the bearing seat, it can drive the movable block to move longitudinally through the threaded connection. When the movable block moves downward, it can drive the concave lens to move longitudinally, thus adjusting the position of the concave lens.

[0011] Furthermore, the drive motor, the active bevel gear, and the driven bevel gear are symmetrically arranged on the inner wall of the component housing. The active bevel gear and the driven bevel gear form a meshing structure. When the drive motor is running, it can drive the active bevel gear to rotate. When the active bevel gear rotates, it can drive the driven bevel gear to rotate through the meshing structure. The rotation of the driven bevel gear can drive the threaded rod to rotate inside the bearing housing. In this way, the transmission between the drive motor and the threaded rod can be realized.

[0012] Furthermore, a mating cylinder is connected to the side surface of the component housing, a protruding thread is connected to the surface of the mating cylinder, a threaded sleeve is fitted onto the surface of the protruding thread, and a rubber ring is connected to the inner wall of the threaded sleeve.

[0013] Furthermore, the docking cylinder and the component housing are an integral structure, and the docking cylinder has the same dimensions as the planar side of the lens body.

[0014] Furthermore, the connecting sleeve and the convex thread are an integral structure, and the threaded sleeve and the convex thread are connected by a thread. When the threaded sleeve rotates on the surface of the convex thread, it can move laterally. When the threaded sleeve disengages from the surface of the convex thread, it is convenient to replace the new lens body.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, when the drive motor is running, it drives the active bevel gear to rotate. The rotation of the active bevel gear drives the threaded rod to rotate through the driven bevel gear. The rotation of the threaded rod drives the concave lens to move downward through the movable block. When the concave lens moves downward until its center is on the same horizontal line as the center of the lens body, the light cannot pass through the concave lens when it hits the surface of the light-shielding coating. The light that hits the inner wall of the concave lens will be refracted to the outside. Then the light will pass through the lens body and be projected into the external environment, thus forming a ring-shaped light-emitting effect. This allows the projector to meet the requirements of the ring projection effect, improving the applicability and practicality of the component.

[0018] 2. In this utility model, the threaded sleeve rotates on the surface of the convex thread and moves outward. When the threaded sleeve disengages from the surface of the convex thread, the original lens body is removed and replaced with a new lens body. Then, the threaded sleeve is fitted onto the surface of the convex thread and rotated in the opposite direction. When the threaded sleeve drives the rubber ring to move to the surface of the lens body, the lens body can be fixed at this time, so that the lens body can be easily replaced.

[0027] This specific embodiment is a projection lamp lens assembly with a ring-shaped light emission effect, and its structural schematic diagram is shown below. Figure 1-7 As shown, the lens assembly includes a housing 1, a reflector 2, and a lens body 3. The reflector 2 is connected to the inner side of the housing 1, and the lens body 3 is located on one side of the housing 1. A bearing seat 4 is installed on the inner wall of the housing 1. A threaded rod 5 is connected through the interior of the bearing seat 4. A driven bevel gear 6 is connected to the end of the threaded rod 5. The threaded rod 5 passes through the interior of the movable block 7. A concave lens 8 is connected to the side surface of the movable block 7. A light-shielding coating 9 is adhered to the inner wall of the concave lens 8. A drive motor 10 is installed on the inner wall of the housing 1, and a drive bevel gear 11 is connected to the output end of the drive motor 10.

[0028] The threaded rod 5 and the movable block 7 are symmetrically arranged on both sides of the concave lens 8, and the threaded rod 5 and the movable block 7 are connected by threads. The drive motor 10, the active bevel gear 11 and the driven bevel gear 6 are symmetrically arranged on the inner wall of the component housing 1, and the active bevel gear 11 and the driven bevel gear 6 form a meshing structure.

[0029] In addition, a docking cylinder 12 is connected to the side surface of the component housing 1, a protruding thread 13 is connected to the surface of the docking cylinder 12, a threaded sleeve 14 is fitted onto the surface of the protruding thread 13, and a rubber ring 15 is connected to the inner wall of the threaded sleeve 14. The docking cylinder 12 and the component housing 1 are an integral structure. The docking cylinder 12 and the lens body 3 have the same dimensions on the plane side. The docking cylinder 12 and the protruding thread 13 are an integral structure. The threaded sleeve 14 and the protruding thread 13 are threadedly connected.

[0030] Working principle: When using the device of this technical solution, the lens assembly is first installed inside the projection lamp. Then, the power is turned on so that the light source starts to emit light. The light is irradiated through the lens body 3. When a ring-shaped light emission effect is needed, the drive motor 10 can be moved. When the drive motor 10 runs, it can drive the active bevel gear 11 to rotate. When the active bevel gear 11 rotates, it drives the driven bevel gear 6 to rotate. When the driven bevel gear 6 rotates, it drives the threaded rod 5 to rotate. The rotation of the threaded rod 5 drives the movable block 7 to move downward through the threaded connection structure. When the movable block 7 moves downward, it can drive the concave lens 8 to move downward. When the concave lens 8 moves downward until its center is on the same horizontal line as the center of the lens body 3, the light cannot pass through the concave lens 8 when it shines on the surface of the light-shielding coating 9. The light that shines on the inner wall of the concave lens 8 will be refracted outward. Then the light will pass through the lens body 3 and be emitted into the external environment, thus forming a ring-shaped light emission effect.

[0031] When the lens body 3 needs to be replaced because it does not meet the usage requirements, the threaded sleeve 14 can be rotated. When the threaded sleeve 14 rotates, it can move outward on the surface of the convex thread 13. When the threaded sleeve 14 moves to the outside of the convex thread 13, the original lens body 3 can be removed and the new lens body 3 can be inserted into the docking cylinder 12. Then, the threaded sleeve 14 is fitted onto the surface of the convex thread 13 and rotated in the opposite direction. The threaded sleeve 14 can move towards the component housing 1 when it rotates in the opposite direction on the surface of the convex thread 13. When the threaded sleeve 14 drives the rubber ring 15 to move to the surface of the lens body 3, the lens body 3 can be fixed, thereby realizing the replacement of the lens body 3.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
