Lighting system based on strip-shaped faculae

Abstract

The invention relates to the field of optical lighting, and discloses a lighting system based on strip-shaped faculae. The lighting system comprises a strip-shaped Fresnel lens, a reflection unit, an incidence unit and a light source; the strip-shaped Fresnel lens is of a semi-cylindrical barrel face structure; the incidence unit is located at the center position of the bottom of the strip-shaped Fresnel lens and comprises a saddle-shaped incidence face, a first semicircular hook face incidence face and a second semicircular hook face incidence face; the reflection unit comprises a first total reflection hook face and a second total reflection hook face; the light source is located in the center of the bottom of the incidence unit; and the Fresnel lens is connected with the incidence unit through the first total reflection hook face and the second total reflection hook face. The lighting system has the beneficial effects that strip line faculae generated by the lighting system are thin and narrow in distribution and good in edge acutance; light strips are evenly distributed and suitable for indoor and outdoor decoration lighting sites; excellent strip line light can be combined into various face-distribution lighting effect, and a wide application prospect is achieved.

Description

technical field [0001] The invention relates to the field of optical illumination, in particular to an illumination system based on striped light spots. Background technique [0002] The window sills on the exterior wall and the window frames above them have always been the embellishment focus of lighting designers, but limited by the limitations of lamps and installation conditions, there has been no ready-made lighting equipment; at the same time, on the indoor corridors, people also It is hoped that some line-shaped light spots will embellish special light and shadow effects. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a lighting system based on striped facula, which emits light at a maximum angle (120-180°) in one direction, and emits light at a small angle (0-10°) in its vertical direction. °) to emit light while ensuring that the illuminance on the light spot of the linear ligh...
