Method of fabrication of illuminating panels containing electroluminescent diodes (LED) and traffic sign obtained with this method

Abstract

Abstract The invention relates to a method of manufacturing a signal lamp panel with light-emitting diodes. The method in accordance with the invention is characterised by the fact that encapsulated LEDs (1) are mounted on a metal support plate (2) made of material suitable for deep drawing, which is bonded by an adhesive layer (4) to a soft plastic film (3); the top side (5) of the plastic film is laminated with copper and is etched and tinned to produce suitable electrical circuits, the LEDs (1) being automatically soldered on by the dip- solder or reflow solder method and the support plate (2) is cut into baseplates which are drawn to form the required shape. Application for signal lamps in motor vehicles. <IMAGE>
