Attachment arrangement for attaching a luminous diode to a rear side of a printed circuit board illuminated from behind has a casing carcass linked to the circuit board, front sides and a rear wall

摘要

Designed as a printed circuit board, a rear wall (RW) (5) has its outer edges flush with the outer sides of side walls (2,4). In a thickened area of the side walls there are openings (7) on the RW's rear side. These openings amount to through-hole-plated drilled holes. Inside the RW there are layers of conductive material.
