LED LIGHTING FIXTURE (VARIANTS) AND HEAT-REMOVING PROFILE AS THE LIGHTING FIXTURE HOUSING Russian patent published in 2018 - IPC F21V29/00 

FIELD: lighting equipment.

SUBSTANCE: group of inventions relates to the field of lighting equipment, namely to the fixed installation, modular construction lighting devices, and is intended for street, industrial, household and architectural and design lighting. Technical result is achieved by using the radiator housing made of heat-conducting material in the form of drawn symmetrical profile, in which the massive heat-conducting base and the directed from the base ribs are made together, wherein the arc-shaped ribs each subsequent bent pair, starting from the central one, reduces the heat-conducting base cross-section by the rib thickness, at that, the ribs themselves are made with a wavy surface, and also containing a pair of made together with the radiator housing vertical posts, extending from the heat-conducting base in the opposite side, at the end of which U-shaped fastening channels with longitudinal notches on the outside are made to accommodate the profile-plate and/or profile-pipe response parts therein with fixation by screws along the longitudinal notches and connected to the arc-shaped ribs central bent pair with formation of the symmetrical closed loops between the posts and the ribs central pair and central closed loop formed by the radiator housing and the profile-plate and/or profile-pipe, having longitudinal notches on the outside; power source placed on the outside of the central closed loop and fixed by screws along the profile plate longitudinal notches, including the housing of a drawn profile with fins and upwards bent ribs along the sides, mounted therein base is also made of a drawn profile, on which the base elements for the printed circuit boards with electronic components placing are located, and side covers with fasteners and possibility of standard seal guides installation; side decorative covers with profile corresponding to the radiator housing profile and the profile plates and/or profile pipes and having through holes.

EFFECT: technical result is expansion of the lighting fixture scope of application, a reduction in the material consumption, increase in reliability, and reduction in the manufacturing and maintenance labor intensity.
