Description

Technical Field

[0001] The invention relates to the technical field of display screens, and in particular to a lens for an outdoor high-hanging display screen. Background Art

[0002] The outdoor high-hanging display screen lens is an optical element that is closely integrated with the display screen. Through its specific optical design, it can improve the propagation and distribution of light, thereby improving the key performance indicators of the display screen such as brightness, uniformity, and viewing angle. According to different application requirements and technical characteristics, display screen lenses can be divided into many types, such as Fresnel lenses, liquid crystal lenses, silicone lenses, etc.; display screen lenses are mainly used to improve display effects, optimize optical performance, and achieve special effects. The existing display screen lenses basically meet the needs, but there are still certain defects; the existing display screen lenses adopt a bracket and lamp bead lens separation structure. After the bracket is formed, the lamp beads need to be assembled into patches. There are many assembly processes and the assembly accuracy deviation is large, which affects the product quality. At the same time, the patch light guide has certain limitations; therefore, it is necessary to design an outdoor high-hanging display screen lens. Summary of the invention

[0003] The purpose of the present invention is to provide an outdoor high-hanging display screen lens to solve the defects of the existing display screen lens, such as multiple assembly processes and large assembly precision deviation, which affects product quality and has certain limitations in patch light guidance.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: an outdoor high-hanging display screen lens comprises a bracket, a lens assembly, a light guide column, a support and a spherical surface, wherein the light guide column in the lens assembly is embedded in a through hole opened on the bracket, a support is provided at one end of the light guide column, and a spherical surface is fixedly connected to the support.

[0005] As a further technical solution of the present invention, the lens assembly is composed of a light guide column, a support, a spherical surface, a primary light guide surface and a secondary light guide surface. One end of the light guide column is provided with a primary light guide surface and a secondary light guide surface.

[0006] As a further technical solution of the present invention, a fixing hole is provided on the bracket.

[0007] As a further technical solution of the present invention, a mounting piece is provided on one side of the bracket.

[0008] As a further technical solution of the present invention, a mounting hole is provided on the mounting member.

[0009] As a further technical solution of the present invention, connection grooves are symmetrically provided on the bracket.

[0010] As a further technical solution of the present invention, a light-guiding layer is fixedly connected to the bracket, and a supporting member is sleeved on the through hole provided in the light-guiding layer.

[0011] The outdoor high-hanging display screen lens provided by the present invention has the advantages that the overall lens assembly is integrally formed, the bracket has high positioning accuracy, the position deviation with the light source is small, and the overall quality of the product is effectively improved. At the same time, the primary light-guiding surface arranged on the lens assembly transmits the received light source to the secondary light-guiding surface and the spherical surface through the principles of refraction and reflection. The secondary light-guiding surface performs light mixing effect processing on the received light and converges it to the light-emitting spherical surface to meet the visual range. The bracket is designed with a black color as a whole, absorbs and shields the stray light released by the light source, so that the light color mixed and converged to the light-emitting spherical surface is uniform and free of stray light. At the same time, the primary light-guiding surface and the secondary light-guiding surface effectively improve the light-guiding and three-primary-color mixing effects. The light source emits light of different wavelengths, which is reflected and refracted N times by the primary and secondary light-guiding parts to make the three-color light fully and evenly mixed, so that when it converges to the light-emitting spherical surface, no light color stratification occurs.
