LED LUMINAIRE Russian patent published in 2024 - IPC F21S13/10 

FIELD: lighting engineering.

SUBSTANCE: invention relates to energy-saving light-emitting diode luminaires, and can be used for lighting of streets, highways, roads, squares and industrial lighting. LED luminaire comprises a radiator housing with LEDs mounted on a flat base, a power supply unit and a fixture unit with a mechanism for changing the angle of inclination of the luminaire. Radiator housing is made hollow with longitudinal ribbing on sides and is equipped with cover, note here that power supply unit is mounted inside radiator housing and inclination angle variation mechanism is arranged at luminaire rear cover. Inner surface of the radiator housing and the outer surface of the housing, including ribbing, are ribbed, and the casing cover is made with vertical ribbing, at the same time a longitudinal open channel is made on its inner side.

EFFECT: creation of reliable and easy-to-manufacture luminaire design with maximum use of flat surface area, on which light-emitting diodes are located, as well as reduced load on the fixture assembly, which prolongs its service life by reducing the length of the lamp, placing the power supply in the cavity of the radiator housing and by arranging the luminaire inclination angle change mechanism in the cavity of the radiator housing, while reducing the negative effect of natural and man-made precipitation.
