Abstract

An optical lens for a light source has an incidence surface receiving light rays emitted from a light source and an aspherical emitting surface optically coupled with the incidence surface for receiving light rays from the incidence surface and emitting light rays received from the incidence surface. The incidence surface defines a cavity for receiving the light source. An opaque or semi-opaque bottom surface adjoins the incidence surface and emitting surface. A lighting device has a substrate, a lighting source located on the substrate, and the optical lens located with the substrate and enclosing the lighting device. A strip light has an elongate substrate having light sources and respective lenses distributed longitudinally along the substrate. Such a strip light using the lens is suitable for lighting the interior of a commercial or domestic refrigerator, chillier cabinet, or other enclosure.
