Description

Technical Field

[0001] The utility model relates to the field of street lamp lenses, in particular to a street lamp lens structure. Background Art

[0002] Street lamp is a common public lighting facility, which realizes the lighting function by projecting light onto the road surface. Since the light radiates in all directions with the light source as the center, in order to concentrate the light to increase the brightness, a lens is generally installed at the light source, such as a street lamp lens structure with publication number CN206593025U in the prior art.

[0003] Lenses refract light to change its direction. Common lenses are usually made of glass and have an ellipsoidal shape, with light emitted from the spherical surface.

[0004] Street lamps are mostly used to illuminate the road surface, while the guardrails on both sides of the highway cannot be illuminated at night, which can easily cause pedestrians or vehicles to collide with the guardrails at night. However, in the prior art, the spherical surface of the lens is relatively smooth, and the light will be emitted from the side, forming a relatively scattered light spot, which makes it difficult to fully illuminate the guardrails on both sides of the highway.

[0027] A plurality of stripes 102 are fixedly disposed at the bottom of the lens body 1. The stripes 102 are distributed at the edge of the bottom of the lens body 1. The middle of the bottom of the lens body 1 is a smooth area 101.

[0028] An isolation gasket 2 is disposed on the top of the lens body 1 , and a moisture absorbing component 4 is disposed on the rear side of the isolation gasket 2 .

[0029] The lens body 1 is mounted on the main body of the street lamp. The light source of the street lamp is located inside the light inlet 103 at the top of the lens body 1. The light emitted by the light source is refracted by the lens body 1 and then irradiated downward. Since a plurality of stripes 102 are provided at the bottom of the lens body 1, the light on both sides of the bottom of the lens body 1 is scattered or removed by the stripes 102, and the light can only be emitted from the smooth area 101. Since the smooth area 101 is similar to a semi-ellipse, the final light spot is similar to a semi-ellipse, which can illuminate the guardrail beside the road, so that the guardrail can be seen at night to avoid collision.

[0030] In order to protect the lens body 1, as Figure 1 , 2 As shown in Figures 6, a transparent anti-fog film 8 is fixedly provided at the bottom of the lens body 1. The main components of the transparent anti-fog film 8 are methacrylic acid and methacrylate, which can prevent external water mist from adhering to the bottom of the lens body 1 and blocking the light. A transparent heat-insulating film 7 is fixedly provided at the top of the lens body 1. The transparent heat-insulating film 7 is located on the inner wall of the light inlet 103. The transparent heat-insulating film 7 is a polyester film, which can block the heat emitted by the light source and reduce the heat of the lens body 1.

Two screws pass through the isolation gasket 2 to fix the lens body 1. Two sealing rings 6 make the isolation gasket 2 closely contact with the street lamp body and the lens body 1 respectively, so that the inner side of the isolation gasket 2 is in a sealed state.

A plurality of heat-dissipating protrusions 304 are fixedly provided on the surface of the heat sink 303. The heat-dissipating protrusions 304 can increase the heat-dissipating area and improve the heat-dissipating efficiency.

[0036] The inner heat conducting sheet 301 on the inner wall of the isolation gasket 2 can absorb the heat emitted by the light source and conduct the heat outward to the heat sink 303 through the heat conducting rod 302. The heat sink 303 is used to dissipate the heat outward, thereby achieving the purpose of heat dissipation when the inner side of the isolation gasket 2 is closed.

[0037] In order to keep the interior of the light inlet 103 dry, Figure 1 , 3 As shown in FIG. 5 , the moisture absorbing component 4 includes a storage box 402, an activated carbon bag 404 capable of absorbing moisture is provided inside the storage box 402, and a detachable sealing plate 403 is provided at the bottom of the storage box 402 to facilitate replacement of the activated carbon bag 404;
