Description

Technical Field

[0001] The utility model belongs to the technical field of lenses, and particularly relates to a lens installation structure. Background Art

[0002] A lens is an optical element, usually made of transparent materials such as glass or plastic, with a specific curved or flat surface that can be used to change the direction of light propagation, focus or diverge light. The lens can focus the light emitted by the LED chip, making the light more concentrated and focused, and increasing the brightness and irradiation distance of the light.

[0003] For example, a Chinese patent with publication number CN209560181U discloses a lens mounting structure, including a substrate and a lens. The substrate adopts a double-layer structure, and the substrate includes an upper substrate and a lower substrate. A card slot is opened at the center of the upper substrate, and a lens is engaged in the card slot. An LED chip is arranged at the center of the upper surface of the lower substrate. The inner wall of the card slot is provided with a plurality of step surfaces, and the inner diameters of the plurality of step surfaces decrease step by step from the outside to the inside.

[0004] When installing the lens as mentioned above, sealant is dotted around the lens, and the sealant will overflow onto the substrate, which is not only not aesthetically pleasing, but also requires the removal of most of the residual sealant when the lens is subsequently replaced, which is not convenient to clean. In addition, the lens is simply installed on the substrate, which is not firm and stable enough. This installation method can easily cause the lens to loosen and shake, thereby affecting the optical performance and stability of the lamp. Utility Model Content
