Description

Technical Field

[0001] This utility model belongs to the field of lens assembly technology, specifically relating to an anti-glare projection lamp lens assembly. Background Technology

[0002] The projector lens assembly is a crucial component of a projector, responsible for focusing light and projecting a specific beam or image. A projector lens assembly typically consists of the projector housing, the projector body, the lens elements, and possibly adjustment mechanisms. The working principle of a projector lens assembly is based on the refraction and focusing of light. When light emitted from a light source passes through the lens elements, the lenses refract and focus the light according to their shape and curvature, thereby projecting the light onto the desired area or forming a specific beam.

[0003] Projector lens assemblies are widely used in various lighting and projection applications, such as stage lighting, outdoor advertising lighting, and architectural projection. With continuous technological advancements and innovation, the application areas of projector lens assemblies will continue to expand and deepen. However, existing lens assemblies exhibit the following problems during use:

[0004] Existing projector lens assemblies sometimes emit excessively intense light during illumination, causing noticeable glare. This can not only affect visual comfort but also cause unnecessary disturbance to the surrounding environment or negatively impact the overall aesthetics of the lighting effect. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an anti-glare projector lens assembly. This lens assembly aims to solve the technical problem that, in the process of illumination, the projector lens assembly sometimes emits excessively strong light, which causes obvious glare. This situation may not only affect visual comfort, but also cause unnecessary interference to the surrounding environment or affect the overall aesthetics of the lighting effect.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides an anti-glare projection lamp lens assembly, which includes a housing, an optical lens, a mounting plate, and a light source control plate. The optical lens is installed inside the housing, the mounting plate is connected to the inner wall of the housing, and the light source control plate is connected to the side surface of the mounting plate. A first motor is installed inside the housing, and a first drive gear is connected to the output end of the first motor. A first bearing is fitted inside the mounting plate, and a rotating rod is connected through the first bearing. A coated plate is connected to one end of the rotating rod, and a first driven gear is connected to the other end of the rotating rod.

[0009] When using the lens assembly of this technical solution, the first motor drives the first drive gear to rotate during operation. When the first drive gear rotates, it drives the rotating rod to rotate through the first driven gear. This allows the rotating rod to drive the coating plate to rotate. After rotating 180°, the coating plate can be positioned between the lamp beads and the optical lens on the light source control board, thereby preventing glare from occurring.

[0010] Preferably, four sets of first bearings, rotating rods and coated plates are provided. The rotating rods form a rotating structure between the first bearings and the mounting plate. The coated plates are made of high-transparency resin plates with nano-silica coating on the surface. The coated plates can reduce reflection and increase light transmittance when exposed to strong light, thereby avoiding glare.

[0011] Furthermore, four sets of first driven gears are arranged in a circular array outside the first driving gear. The first driving gear and the first driven gear form a meshing structure. When the first driving gear rotates, it can drive the first driven gear to rotate through the meshing structure. The rotation of the first driven gear can drive the rotating rod to rotate, thereby realizing the rotation of the coating plate.

[0012] Furthermore, a second bearing is fitted inside the housing, and a bracket is connected through the inside of the second bearing. An inclined cylindrical lens is connected to the end of the bracket, and a driven bevel gear is connected to the surface of the bracket. A second motor is installed on the inner wall of the optical lens, and a driving bevel gear is connected to the output end of the second motor.

[0013] Furthermore, the bracket forms a rotating structure with the housing through the second bearing. When the bracket is subjected to force, it can rotate inside the second bearing, which makes it easy to adjust the position of the inclined cylindrical lens.

[0014] Furthermore, there are four sets of angled cylindrical lenses. The angled cylindrical lenses are made of high-transmittance resin material. When light passes through the angled cylindrical lenses, it can be refracted through its angled surface, which makes it easy to adjust the angle of light illumination.

[0015] Furthermore, the driving bevel gear and the driven bevel gear form a meshing structure. When the driving 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 support to rotate, thus realizing the transmission between the second motor and the support.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In this invention, when the first motor is running, it can drive the first driving gear to rotate. When the first driving gear rotates, it can drive the rotating rod to rotate through the first driven gear. The rotation of the rotating rod can drive the coating plate to rotate. After the coating plate rotates 180°, it can be located between the lamp bead and the optical lens of the light source control board. In this way, the coating plate can prevent glare and improve the visual comfort of the lens assembly.

[0019] In this invention, when the second motor is running, it drives the active bevel gear to rotate. When the active bevel gear rotates, it drives the bracket to rotate through the driven bevel gear. The rotation of the bracket can drive the inclined cylindrical lens to rotate. After the inclined cylindrical lens rotates 45°, it can be located on the convex side of the optical lens. At this time, the light can be refracted when it passes through the inclined cylindrical lens. This can adjust the illumination range of the lens assembly, thereby improving the practicality of the lens assembly. Attached Figure Description

A coated through plate 9 is connected to the end of the rotating rod 8, and a first driven gear 10 is connected to the other end of the rotating rod 8.

[0029] The first bearing 7, the rotating rod 8 and the coated plate 9 are arranged in four sets. The rotating rod 8 forms a rotating structure between the first bearing 7 and the mounting plate 3. The coated plate 9 is made of high-transparency resin plate with nano-silica coating on the surface. The first driven gear 10 is arranged in four sets in a ring array outside the first driving gear 6. The first driving gear 6 and the first driven gear 10 form a meshing structure.

[0030] In addition, a second bearing 11 is fitted inside the housing 1, and a bracket 12 is connected through the inside of the second bearing 11. An inclined cylindrical lens 13 is connected to the end of the bracket 12, and a driven bevel gear 14 is connected to the surface of the bracket 12.

When the first motor 5 is running, it can drive the first drive gear 6 to rotate. When the first drive gear 6 rotates, it can drive the first driven gear 10 to rotate. When the first driven gear 10 rotates, it can drive the rotating rod 8 to rotate inside the first bearing 7. When the rotating rod 8 rotates, it can drive the coated plate 9 to rotate. After the coated plate 9 rotates 180°, it can be positioned between the lamp bead and the optical lens 2 of the light source control board 4. In this way, the glare can be avoided through the coated plate 9.

[0032] When the second motor 15 is running, it can drive the active bevel gear 16 to rotate. When the active bevel gear 16 rotates, it drives the driven bevel gear 14 to rotate. The rotation of the driven bevel gear 14 can drive the bracket 12 to rotate inside the second bearing 11. The rotation of the bracket 12 can drive the inclined cylindrical lens 13 to rotate.
