LANDSCAPE LED light unit (optional)

摘要

The invention relates to lighting engineering and can be used for landscape lighting and lighting of pedestrian and park areas. The technical result is to increase the luminous efficiency of the light unit. The technical result is achieved in that the topographical LED light unit comprises a cylindrical body, a diffuser, heat conducting base of the LED light sources. LED light sources are located circumferentially near the lens on a flat heat conducting base in the form of a disk with a variable cross section, which is part of a thermally conductive tube perpendicular to its axis and having inside cooling fins of heat conductive material. Between the optical axis of the LED light source and the surface of the heat conducting tube disposed mirror, which plane is parallel to the optical axis of the LED light source. In the second case, the device comprises a cylindrical body, a diffuser, heat conducting base of the LED light sources and the reflector. LED light sources are located circumferentially near the lens on a flat heat conducting base in the form of a disk with a variable cross section, which is part of a thermally conductive tube perpendicular to its axis and having inside cooling fins of heat conductive material. Between the optical axis of the LED light source and the heat conducting tube surface mirror arranged to vary its tilt plane, and a reflector disposed under the mirror, at one end fastened to the tube, and the other rests on a plate with holes. In the third case, the device comprises a cylindrical body, a diffuser, heat conducting base of the LED light sources and the reflector. LED light sources are located circumferentially near the lens on a flat heat conducting base in the form of a disk with a variable cross section, which is part of a thermally conductive tube perpendicular to its axis and having inside cooling fins of heat conductive material. The reflector having different angles of cone portions, is fixed at one end of the tube and the other rests on a plate with holes. The housing and the top of the diffuser formed vents. The diffuser consists of two parts, upper and lower transparent matte. Above the upper part of the diffuser cap located at a predetermined distance. Location longitudinal planes of LED light sources on the heat conducting base may be varied, with adjustment of intensity. 3 bp ZP 4, 5 yl.
