LIGHT-EMITTING DIODE LIGHTING FIXTURE Russian patent published in 2014 - IPC F21S13/10 

FIELD: electricity.

SUBSTANCE: invention refers to the sphere of lighting engineering, in particular to light-emitting diode (LED) street lighting fixtures. LED lighting fixture includes housing with radiator fixed on it, fasteners of LED matrix, protective glass and holder with opening and mechanism for fixing tubular console of the substructure; at that housing of the fixture is ready-made as a base over windows with radiator and at least one LED matrix mounted in its central part. Radiator is mounded at the base over windows. At the base sides there are fixed longitudinal lateral sides connected by cut slots with air flow guides installed over the radiator and at least two air flow guides of the holder which are made as ribs and installed perpendicular to longitudinal axis of the fixture. Front section of the housing is made as air flow guides mainly parallel to longitudinal axis of the fixture. Holder of the lighting fixture is made of a set of air flow guides connected to each other additionally by means of at least three plates; at that the upper plate is connected by cut slots to at least two guides in the housing.

EFFECT: increasing efficiency of heat removal.
