General purpose LED spotlight module and multi-module LED spotlight

摘要

FIELD: lighting engineering.SUBSTANCE: invention relates to lighting equipment and can be used in the manufacture of lighting equipment for architectural illumination of buildings, sports grounds, theatre auditoriums and concert halls, city squares, airports, railway facilities. Another result is the manufacturability and interchangeability of the LED modules. As an additional positive result, you can indicate the ease of assembly and maintenance of the LED spotlight. Module of the LED spotlight contains a heat-conducting body-radiator, the extruded profile of which is formed by an outer closed wall and an inner closed wall of the main chamber, connected by radial walls, together forming peripheral internal chambers, the walls of each of which form the through ventilation ducts of the body-radiator; a heat conducting plate, pressed by a lateral surface into the main chamber; a LED board mounted on the surface of said heat-conducting plate, with the possibility of heat exchange; optical system; rear end cap having through-slots, which are a continuation of the ventilation channels of the radiator housing. Multi-module floodlight contains two or more modules connected by a common shroud, the outer wall of the radiator housing of each module is provided with a longitudinal shaped groove, for example, a T-shape for locating a connector element for connecting an adjacent LED module with a gap sized by the length of the connector element.EFFECT: technical result of the claimed invention is to improve the thermal operation of the radiation sources by creating an effective cooling airflow.7 cl, 8 dwg
