Verfahren zur Befestigung einer Leistungsleuchtdiode an einem Kühlkörper und Signaleinrichtung mit solcher Leuchtdiode |
摘要 |
The method involves fixing a metallic base (2) of an electroluminescent power diode e.g. LED (1), on a metallic heat radiator (3) by laser welding points (11). The metallic base is made of copper, and the radiator unit is lined by a metal layer of nickel to absorb laser light. Centers of welding points are distributed regularly on a contour parallel to an exterior perimeter of the base. An independent claim is also included for a signaling or lighting device for an automobile. |
