Unless otherwise defined, all terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that the conventional terms should be interpreted as having a meaning that is consistent with their meaning in the relevant art and this disclosure. This disclosure is to be considered as an example of the invention and is not intended to limit the invention to the particular embodiments.
Example one
In order to solve the technical problem, the application provides a LED guardrail lamp lens in order to solve glare and the illumination degree of consistency problem in the guardrail lamp illumination. As shown in fig. 1, the guardrail lamp lens 1 of the present embodiment includes a refractive lens and a reflective lens. The guardrail light lens may be an assembly formed by assembling separate refractive and reflective lenses together. The guardrail lamp lens 1 in the embodiment adopts an integrated design, and comprises two parts, namely a refractive lens and a reflective lens. The refracting lens comprises a convex lens body 11 with a fan-shaped cross section, an inwards concave arc surface on one side of the convex lens body is used as a light inlet surface and faces one side of the guardrail lamp lens 1 towards the light source, and an outwards convex arc surface on one side of the convex lens body is used as a light outlet surface and faces the light outlet side of the guardrail lamp lens 1, after the guardrail lamp lens and the light source are assembled into the guardrail lamp, a part of light beams emitted by the guardrail lamp light source enter the refracting lens through the light inlet surface of the convex lens body 11 for refraction, and then are emitted through the light outlet surface of the convex lens body 11. The reflection lens includes a cylindrical lens body 12 with a sector cross section, and a polarization structure is arranged at one end of the cylindrical lens body 12 as a light emergent part. As shown in fig. 3, the polarization structure of the present embodiment is a plurality of serrations 121 provided at the end of the lenticular lens body 12. Each of the serrations 121 has a vertical surface perpendicular to the end surface of the lenticular lens body 12 and an inclined surface having one end intersecting the vertical surface, and the inclined surfaces of the plurality of serrations 121 of the light-emitting portion are inclined in the same direction to form a uniform polarization direction. The other end of the cylindrical lens body 12 is provided with a cavity 122 with a sector-shaped cross section. The fan ring shape in the invention means that: a circular ring is cut into at least two parts along a certain radius direction, and the shape of each part is fan-shaped. The closer to the end of the lenticular lens body 12 where the polarization structure is located, the farther the inner sidewall 1221 of the cavity 122 (i.e., the sidewall formed by the inner annular arc edge of the sector-shaped cross section) is from the axis of the lenticular lens body 12 to form a reflecting surface for reflecting light. The central angle a of the cross-sectional fan shape of the lenticular lens body 12 in this embodiment is larger than 180 ° (e.g., 240 ° in fig. 2), so that an included angle of less than 180 ° (e.g., 120 ° in fig. 2) is formed between two end faces formed by both end portions of the fan shape in the cross-section thereof. The central angle of the sector in the cross section of the convex lens body 11 is less than 180 °, and it is exactly the sum of the central angle of the sector in the cross section of the lenticular lens body 12 and the central angle of the sector in the cross section of the convex lens body 11 that is equal to 360 ° (for example, the central angle b of the sector in the cross section of the lens body 11 in fig. 2 is 120 °). The convex lens body 11 is located in an included angle between two end portions of the sector shape on the cross section of the lenticular lens body 12 (i.e. an included angle smaller than 180 degrees is formed between two end surfaces formed by the two end portions of the sector shape on the cross section), and just makes both end portions of the sector shape on the cross section of the convex lens body 11 and the sector shape on the cross section of the lenticular lens body 12 respectively join together, so that the lens is surrounded by the lens within 360 degrees on the cross section of the whole guardrail lamp lens 1. Light emitted from both end surfaces 111 formed at both end portions of the sector shape in the cross section of the convex lens body 11 can enter the lenticular lens body 12 through both end surfaces 123 formed at both end portions of the sector shape in the cross section of the lenticular lens body 12. The two end faces formed by the two fan-shaped end portions on the cross section of the cylindrical lens body 12 are used as light incident faces, light entering through the light incident faces is transmitted to the reflecting faces and then reflected to the light emergent portions, and the light is emitted towards the polarization direction after the transmission direction is changed by the polarization structure of the light emergent portions. The light-emitting part of lenticular lens body 12 is towards the light-emitting side of guardrail lamp lens 1, and the fan-shaped opening of lenticular lens body 12 cross section is towards guardrail lamp lens 1 towards the direction on ground, and convex lens body 11 is arranged in the fan-shaped opening of the below of lenticular lens body 12. So that a part of the light beam entering the guardrail lamp lens 1 is emitted through the refractive lens, and the other part of the light beam is condensed through the reflective lens and is emitted to the polarized direction through the polarized structure. As shown in fig. 2, the cross-sectional fan radius of the lenticular lens body 12 in the present embodiment is preferably larger than the cross-sectional fan radius of the convex lens body 11. And as shown in fig. 1, the height of the lenticular lens body 12 is greater than the thickness of the convex lens body 11. So that the convex lens body 11 of the refractive lens can be designed to have as large a divergence angle as possible, thereby providing a large-angle light of low intensity for a wide-range illumination at a close distance. And the upper portion of convex lens body 11 is surrounded to the lenticular lens body 12 of reflection lens, and the wide-angle light that jets out through the convex lens body 11 enters into the lenticular lens body 12, reaches the plane of reflection of lenticular lens body after the reflection to light-emitting portion and jets out towards the polarisation direction, and the incline direction of inclined plane on serration 121 on the reasonable design light-emitting portion for the light-emitting portion jets out towards the direction of road polarisation and jets out, forms the high central light intensity light of low-angle, throws light on far away to the road.
Preferably, the guardrail light lens further comprises a mounting structure 13. The mounting structure 13 may be a fastener, a screw hole, or the like provided on the end of the lenticular lens body 12 where the cavity 121 is provided, and the hurdle lamp lens 1 may be assembled to the hurdle lamp through the mounting structure 13.
