Abstract

1. Lighting module with LEDs (LED module), consisting of an ultra-bright, powerful LED crystal or block of crystals, a mounting (for example, printed) circuit board with current-carrying contacts, a reflector for controlling the light flux of the LED crystal, a radiator for cooling the core of the crystal, and a protective glass (in the case with a protective glass), characterized in that, in order to reduce material consumption, the complexity of manufacturing and increase the efficiency of heat removal from the active zone of the light-emitting crystal, mounting the armor plate, reflector and radiator are made in a single unit from one thin piece, with high coefficients of thermal conductivity and reflection of the metal, by longitudinally-transverse bending with minimal deformation of the flat, in the initial state, the workpieces, excess metal during molding are doubled and pulled into the edges of the variable heights located radially along the contour; the fins provide efficient heat removal from the radiator and, through it, from the “pn” transition of the LED crystal into the surrounding space and give the necessary mechanical rigidity to the entire system in the meridional plane; the area of the radiator between the ribs (facets) has a design shape and performs the function of a reflector, provides a given light distribution; the neck is made in the form of a flat platform, serves as the base of the wiring panel and provides heat removal from the LED mounted directly on it to the radiator and further into the surrounding space, without intermediate heat-insulating and fastening elements; a transverse annular rift is provided at the bottom of the radiator to give a reflector
