VANDAL-PROOF LIGHT DEVICE Russian patent published in 2024 - IPC F21S8/00 F21V15/01 

FIELD: lighting engineering.

SUBSTANCE: invention relates to lighting engineering, in particular to protected projector-type illuminators or lamps. Vandal-proof lighting device comprises a metal housing, in the form of a rectangular parallelepiped, on the rear wall there is a radiator, side faces connected by a bridge with holes for connecting the lighting device to the attachment system, inside the metal housing there is an aluminium heat conductor with a fixed printed-circuit board with a light-emitting diode having secondary optics, and the outlet hole is covered with an optically transparent screen. Light-emitting diode optical radiation is directed to the mirror coating of the mirror reflector made of flat elastic material having variable thickness, which directs the light beam parallel to the printed-circuit board with the light-emitting diode. Front face of the metal housing directed towards the light beam propagation side is made of high-strength metal in the form of a triangular prism. In the lower face of the housing with an outlet hole, a flat mirror reflector is fixed, the inclination angle of which is determined by the angle of inclination of the curved section of the thicker part of the mirror reflector.

EFFECT: high reliability of the anti-vandal light device due to prevention of destruction of optical and electronic components of the light device, as well as due to use of impact-resistant materials.
