Description

Technical Field

[0001] This utility model belongs to the field of lens technology, specifically relating to a lens with high space utilization and low glare. Background Technology

[0002] With the development of the lighting market, people's demand for lamps is increasing, and their requirements for energy saving and light quality are also becoming higher. Energy saving requires high luminous efficacy. Under the same optical efficiency, the more light sources there are, the higher the luminous efficacy. This requires lamps to accommodate more LEDs within the same size, resulting in high space utilization. UGR (Uniform Glare Ratio) is one of the important parameters of light quality, and lamps also need to reduce UGR to improve light quality.

[0003] Currently, conventional industrial and mining lamp lenses on the market mainly adopt the following three optical solutions: First, the glass solution, which has high space utilization but cannot control the lamp angle and has high UGR; second, the ring lens solution, which has high space utilization and can be made at various angles, but cannot control the light direction in the tangential direction of the lens; and third, the single point lens multi-in-one solution, which has low UGR but low space utilization.

[0004] Therefore, there is an urgent need for a lens that has high space utilization and low glare, which can both improve space utilization and reduce UGR to achieve low glare. Utility Model Content

[0005] The purpose of this invention is to provide a lens with high space utilization and low glare, thereby solving the problems mentioned in the background art. The lens provided by this invention has the characteristics of both improving space utilization and reducing UGR to achieve low glare.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lens with high space utilization and low glare, comprising a lens body, wherein a plurality of lens rings are integrally formed on the lens body, and the lens rings include a plurality of lens portions connected in sequence, wherein the light-emitting surface of the lens portion has a rhomboid protrusion structure and the light-incoming surface of the lens portion has a hemispherical groove structure.

[0007] Furthermore, in this invention, the lens body is made of polycarbonate.

[0008] To further improve space utilization, the edges of the rhomboid protrusions in the lens portions of adjacent lens rings are tangent.

[0009] To achieve a low-glare effect, a light-blocking angle is further formed between the rhomboid protrusions of two adjacent lens sections.

[0010] To achieve adjustment of the light emission angle, the lens ring further includes a first lens ring and a second lens ring, with the first lens ring having a beam angle of 60° and the second lens ring having a beam angle of 90°, and the first lens ring and the second lens ring are alternately arranged.

[0011] To achieve a sealed and waterproof seal, a first adhesive groove is provided on the circumference of the light-gathering surface of the lens body.

[0012] To accommodate the installation of sensors and enhance the functionality of the luminaire, a through hole is further provided at the center of the lens body.

[0013] To achieve a sealed and waterproof effect, a second adhesive groove is provided on the light-inlet surface of the lens body on the circumferential side of the through hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The lens body of this utility model has several lens rings integrally formed on it. The lens rings include several lens parts connected in sequence.

The diamond-shaped protrusion structures of adjacent lens parts can absorb and reflect large-angle light, thereby reducing the light intensity of large-angle light, reducing UGR, and achieving a low-glare effect.

[0016] 2. The edges of the rhomboid protrusions between the lens parts of the adjacent lens rings of this utility model are tangent, so that there is no gap between the lens parts, thereby effectively improving the space utilization rate.
