High-brightness wide-angle polarizing lens

Abstract

This utility model belongs to the field of lens technology, and specifically relates to a high-brightness, large-angle polarizing lens, comprising a lens body with a light entrance aperture. The lens body includes a substrate and triangular prism-shaped protrusions and semi-conical protrusions disposed on the substrate. Compared with the prior art, this utility model has at least the following advantages: Through ingenious structural design, LED light is effectively reflected in a large-angle direction. Because the semi-conical protrusions have an arc-shaped design, they more easily project light onto the target area, increasing the brightness of the target area. Adding triangular prism-shaped protrusions as a reflective structure enhances brightness and reduces light loss.

Description

Technical Field

[0001] This utility model belongs to the field of lens technology, and specifically relates to a high-brightness, large-angle polarizing lens. Background Technology

[0002] In the field of refrigerator lights, it is necessary to design high-brightness, wide-angle optical lenses within a limited space, but existing lenses cannot achieve the above technical effects.

[0003] In view of this, the present invention aims to provide a high-brightness, wide-angle polarizing lens, which, through ingenious structural design, can achieve high brightness and wide angle to meet the new requirements of the refrigerator light industry for lenses. Utility Model Content

[0004] The purpose of this invention is to provide a high-brightness, wide-angle polarizing lens that addresses the shortcomings of existing technologies. Through ingenious structural design, it achieves both high brightness and a wide angle, thereby meeting the new requirements for lenses in the refrigerator light industry.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-brightness, wide-angle polarizing lens includes a lens body with an entrance aperture. The lens body includes a substrate and a triangular prism-shaped protrusion and a semi-conical protrusion disposed on the substrate.

[0006] As an improvement of the high-brightness, large-angle polarizing lens of this utility model, the longitudinal section of the semi-conical protrusion lies horizontally on the substrate.

[0007] As an improvement of the high-brightness, large-angle polarizing lens of this utility model, the small head of the semi-conical protrusion is positioned close to the triangular prism protrusion.

[0008] As an improvement of the high-brightness, large-angle polarizing lens of this utility model, the bottom surface of the triangular prism-shaped protrusion is integrally formed with the substrate, and the bottom surface of the semi-conical protrusion is integrally formed with the substrate.

[0009] As an improvement of the high-brightness, large-angle polarizing lens of this utility model, the acute angle formed between the side of the triangular prism-shaped protrusion away from the semi-conical protrusion and the substrate is greater than the acute angle formed between the side of the triangular prism-shaped protrusion closer to the semi-conical protrusion and the substrate.

[0010] As an improvement of the high-brightness, large-angle polarizing lens of this utility model, the acute angle formed between the side of the semi-conical protrusion away from the triangular prism protrusion and the substrate is greater than the acute angle formed between the side of the semi-conical protrusion closer to the triangular prism protrusion and the substrate.

[0011] Compared with the prior art, the present invention has at least the following advantages: First, through ingenious structural design, LED light is effectively reflected in a large-angle direction.

[0012] Secondly, because the semi-conical protrusion is an arc-shaped design, it is easier to project light onto the target area, which can increase the brightness of the target area.

[0013] Third, adding triangular prism-shaped protrusions as a reflective structure can enhance brightness and reduce light loss. Attached Figure Description

[0020] The present invention will now be further described with reference to the accompanying drawings and specific embodiments, but the implementation of the present invention is not limited thereto.

[0021] like Figure 1-6 As shown, this utility model provides a high-brightness, large-angle polarizing lens, including a lens body 1 with a light entrance aperture 2. The lens body 1 includes a substrate 11 and a triangular prism-shaped protrusion 12 and a semi-conical protrusion 13 disposed on the substrate 11. In use, an LED light is placed inside the light entrance aperture 2. The triangular prism-shaped protrusion 12 acts as a reflective structure to enhance brightness and reduce light loss. The semi-conical protrusion 13 has an arc-shaped design, making it easier to project light onto the target area, thereby increasing the brightness of the target area. This utility model, through its ingenious structural design, effectively reflects LED light at a large angle.

[0022] The longitudinal section of the semi-conical protrusion 13 lies horizontally on the substrate 11, thus making its light-emitting surface arc-shaped.

[0023] The small head of the semi-conical protrusion 13 is positioned close to the triangular prism protrusion 12, while the large head faces outward. A V-shaped recess is formed between the semi-conical protrusion 13 and the triangular prism protrusion 12.

[0024] The bottom surface of the triangular prism protrusion 12 is integrally formed with the base 11, and the bottom surface of the semi-conical protrusion 13 is integrally formed with the base.

[0025] The height of the triangular prism protrusion 12 can be less than, equal to or greater than the height of the semi-conical protrusion 13 when it is lying horizontally. The light reflected from the triangular prism protrusion 12 is reflected obliquely, which can enhance the brightness, achieve high brightness and reduce light loss.

[0026] The acute angle formed between the side of the triangular prism-shaped protrusion 12 furthest from the semi-conical protrusion 13 and the substrate 11 is greater than the acute angle formed between the side of the triangular prism-shaped protrusion 12 closest to the semi-conical protrusion 13 and the substrate 11. This achieves large-angle polarization.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and structure of the present invention, the scope of which is defined by the appended claims and their equivalents.
