LIGHTING DEVICE AND ROAD LIGHTING FIXTURE, CONTAINING LIGHTING DEVICE

摘要

FIELD: lighting.;SUBSTANCE: lighting device comprises LED light source (302), a reflector (301), a holding unit to hold the LED light source reflector, and a base. The reflector (301) has a reflecting surface (3011) formed by parabolic curve rotation about the first axis (y) by a predetermined angle, the reflector has an input at the parabolic curve vertex. The said first axis is coplanar with the said parabolic curve and substantially perpendicular to the axis (x) of symmetry of the said parabolic curve and is located in or outside the said input. The LED light source (302) is located at the input of the said reflector. The holding unit is rotatably connected to the base so that the said holding unit rotates about the second axis (z) which is perpendicular both to the optical axis (x^') of the beam created by the lighting device, and to the first axis (y).;EFFECT: achieved effective reduction or elimination of the negative effect of glare on the road surface.;13 cl, 6 dwg
