LUMINAIRE Russian patent published in 2021 - IPC F21S8/00 

FIELD: lighting engineering.

SUBSTANCE: invention relates to lighting engineering, in particular to the designs of lighting devices with light-emitting diodes intended for lighting, mainly closed rooms with temporary stay of people. The claimed luminaire contains a translucent housing made of a polymer material in the form of a tube with end caps, equipped with mounting elements for hanging, an elongated board with LEDs located in the housing, a bearing assembly of two identical radiator supports, each in the form of an elongated heat-dissipating profile of a C-shaped section, with a section curved along the arc of a circle, the radius of which corresponds to the inner radius of the housing, which is a heat-dissipating element, and with a section oriented along the radius of the specified arc of a circle, the end of which is equipped with two shelves with the formation of a groove. The radiator supports are placed in the housing mirror-symmetrically, and in the oppositely arranged longitudinal grooves of the radiator supports, a board with LEDs is installed horizontally, the surfaces of the radiator supports oriented along the radius facing the LEDs, are mirror-reflecting or diffusely reflecting and are elements of the formation of the luminous flux. At the same time, components of the power supply system are located in the housing, made with the possibility of regulating the speed of increasing and decreasing the luminous flux, to which a motion sensor is connected, placed on an additional board installed in the housing.

EFFECT: simplification of the design, an increase in reliability due to improved heat dissipation, a reduction in material consumption, a reduction in weight, a reduction in the complexity of manufacturing and a simplification of assembly, as well as a reduction in cost.
