A LED luster includes a frame the elements of which are heat tubes with zones of at least heating and cooling, powerful light-emitting diodes installed with provision of thermal contact at zones of heating of heat tubes, cooling zone of those is arranged with developed surface of heat exchange due to its equipment with at least one rib as a plate, and splitter of luminous flux, according to the invention the rib as a plate is brought into coincidence with pulsation heat tube the loops of which have heating and cooling zones. The heating zone of the loops of pulsing heat tube is placed in the basis of the rod and is connected with provision of thermal contact to the cooling zone of the heat tube and the body of the rib, and the cooling zone of the loops of pulsation heat tube is placed in the plane of the rib out of the boundaries of the heating zone of the pulsation heat tube and is connected with provision of thermal contact to the body of the ribs. In the body of rib two groups of through openings are provided, the first group of the through openings is arranged between the neighboring loops of the pulsation heat tube in the area of the heating zone of the loops, and the second group of the through openings is provided in the body of the rib in the loops of the pulsation heat tube just out of the heating zone of the loops. The through openings of the first group have mostly shape of a triangle one of the apexes of which is directed to the zone of contact of the rib with the cooling zone of the heat tube, and the maximal dimension of the opposite basis of the triangle is equal to the distance between the neighboring loops. The through openings of the second group are mostly in form of a circle maximal diameter of which is equal to the distance between the branches of the respective loops of pulsation heat tube. Additionally the LED luster can include an electric fan for forced blowing round the ribs with environmental air. |
