Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. And the features in the embodiments can be combined with each other.

[0031] Such as figure 1 , 2 As shown, a convex lens type guardrail lighting fixture includes a lighting lamp 1 and a convex lens cover 2, and the lighting lamp 1 is an LED lamp. A light-cutting reflector 3 is arranged above the convex lens cover 2 . The surface of the light-cutting reflector 3 is a curved surface, and the slope of the curved surface is small to large, and the recycled light is scattered to the road surface for illumination. The curve of the curved surface satisfies the following formula: y=0.0039x 3 -0.044x 2 +0.3464x-0.4126, where 0<x<2.7.

[0032] Also includes a fixed plate 4, the convex lens cover 2 is arranged on the fixed plat...

Abstract

The invention discloses a convex lens type guardrail illumination lamp which comprises an illumination lamp and a convex lens cover, wherein a body of the convex lens cover comprises a plane and a light gathering curve surface; a triangular groove is formed in the plane, and comprises a horizontal side wall; one corner of the triangular groove corresponding to the horizontal side wall is positioned under the horizontal side wall; a reverse triangular structure is formed; the light gathering curve surface of the convex lens cover is arranged in a way of facing a pavement; an illumination lamp is arranged in the center of the triangular groove; the center of the triangular groove horizontally deviates 1mm to 3mm from the center of the light gathering curve surface; and the horizontal deviation direction is a vehicle driving direction along with a lane. A strong light part of the lamp emits light in the vehicle driving direction, so that high illumination comfort degree in the driving direction is ensured; the glare threshold increment is lower than 1 percent; a light collecting design is used on the top of the lens; the luminous efficiency of the lens is improved by 5 percent or higher; and excellent light interception performance is realized.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a reflective lighting fixture for a forward light guardrail. Background technique [0002] With the rapid development of national highway construction, there are more and more complex traffic sections such as urban viaducts, overpasses, cross-river and sea bridges, and turning ramps at the entrance and exit of expressways. For these special sections, ordinary high poles or street lights are used. Not only It destroys the harmony of the landscape of the original building, and at the same time, there are serious defects in uniformity, induction, light pollution, etc., which is not conducive to the safety and comfort of driving, and also affects the lives of surrounding residents. LED guardrail lights just provide a perfect solution for the above-mentioned bridges, urban interchanges, and expressways. [0003] In recent years, the development of LED guardrail lights has gradually matured, whic...
