FIELD: electricity.SUBSTANCE: method for manufacturing of LED light fixtures includes the following stages: LED groups installed at least on one printed circuit board made on the metal base are fixed to the bearing metal case by means of cold compression; the printed circuit board and the equipped radiator are fixed; metals in the metal base of the circuit printed board and case are extruded, then further compression of metals is performed, at that expansion of the compressed metals is limited at sides by sliding movable heads; equipment is returned into initial position and the connected part is removed from the circuit printed board and case; a power supply source and a terminal block are installed into the case of LED light fixture; the terminal block, the power supply source and the LED group are connected electrically; protective optical dissipating glass is installed and the side cover is installed at the fixture case.EFFECT: improving heat transfer from LEDs to the radiator, increasing efficiency of the process assembly line of LEDs and improving its automation level.6 cl, 4 dwg |
