The support device for a power LED comprises an insulator support (2) of plastic material, a heat sink element (S) of metal such as copper and means for electric connection of electrodes (1a,1b) of the LED (1). The means for electric connection comprise legs (7a,7b,17a,17b) fastened on the initiator support (2) and tongues (12a,12b) which become insulated from the heat sink element (8) after rupturing temporary links or shunts (13). The body of the LED (1) is fastened on a zone of the heat sink element (8), and the heat sink element is assembled with the insulator support (2) by cooperation of openings (9) provided in the heat sink element and projecting pieces (4,5,6) are provided on the insulator support. The heat sink element (8) comprises two V-openings (10a,10b) in the direction of the fastening zone of the LED, and the electrodes (1a,1b) are connected to the tongues (12a,12b) comprised in the V-openings. The power LED (1) can produce a luminous flux of at least 30 lumens. The fastening zone for the LED is constituted by the central zone of the heat sink element (8), and two opposite V-openings starting at the contour of the heat sink element are directed to the central zone. The tongue (12a,12b) is constituted by a part cut in the sheet or plate forming the heat sink in correspondence with the V-opening. The electrodes (1a,1b) of the LED are point-soldered, in particular by laser, to the tongues. A method (claimed) for manufacturing the support device (claimed) comprises the preparation of the insulator support (2) equipped with the legs for electric connection and of the heat sink (8) with the LED fastened by an adhesive, mechanically assembling the heat sink and the insulator support and ensuring the electric connection of the electrodes with the tongues. The links or shunts (13) between the tongues (12a,12b) and the heat sink element (8) are captured so to obtain slits (F) which ensure electric insulation of the tongues from the heat sink element. |
