Optical lens for forming a narrowly directed light beam along the surface

Abstract

The utility model pertains to lighting technology, specifically optical elements for LED light sources, and can be used in lighting devices designed to detect surface imperfections during construction and finishing work. The optical lens comprises a transparent body with an internal cavity for housing an LED light source, a central optical portion, and lateral optical surfaces. The central optical section is designed to generate a focused light beam, while the lateral optical surfaces are inclined and provide light redistribution. The lens is designed to generate a narrowly focused light beam directed at a small angle to the illuminated surface, with the light beam propagating primarily along the illuminated surface. The technical result consists in increasing the efficiency of detecting surface irregularities and reducing the blinding effect on the user.
