  • Patent number: 9933136
    Abstract: A lighting apparatus, in particular in the form of ceiling spots, with a perforated panel having at least one aperture for light to pass through, as well as a lens arranged so as to be concealed behind the perforated panel to emit a bundle of light beams that narrows on its way from the lens to the perforated panel, passes through the aperture for light to pass through, and broadens again after leaving the perforated panel. The lens is shaped in such a manner that a direct beam portion and/or direct light portion emitted without reflection from the lens and an indirect beam portion and/or indirect light portion emitted with reflection from the lens have essentially identical beam angles, and each essentially completely make up and/or fill out the overall bundle of light beams emitted by the lens.

    Abstract: A lighting device, in particular in the form of a ceiling, wall, floor or outside light, having a punctiform light source, preferably in the form of an LED, and a lens assigned to the light source, which has a light entry recess in the form of a bowl or blind hole, which deflects at least part of the incident light, indirectly or directly, onto a totally reflecting and/or mirrored lateral surface, which in turn deflects the light onto a light exit surface, which forms a front side of the lens located opposite the light entry recess. The lateral surface of the lens, which deflects the light coming directly or indirectly from the light entry surface onto the light exit surface by means of total reflection and/or mirroring, is provided with a multiplicity of facets.
