Abstract:
The invention relates to an electronics card (1) comprising a printed circuit board (2) and a piece of equipment (3) such as a motor or a loudspeaker fastened to said printed circuit board (2). The piece of equipment (3) is fastened to a face (4) of the printed circuit board (2) by snap-fastening in metal clips (6, 7) that project from said face (4), each clip (6, 7) having a first end (8, 9) fastened to said face (4) of the printed circuit board (2) by soldering, and a second end (11, 12) bearing resiliently on a corresponding portion of the piece of equipment (3) for holding it pressed against said face (4) of the printed circuit board (2). The invention applies in particular to electronics cards for motor vehicles.
Abstract:
The invention relates to a lighting unit (1) for illuminating at least one edge face of a light guide plate (9) designed to backlight a digital screen panel (11). The unit (1) has a printed circuit board (2) designed to be mounted behind the light guide plate (9), and at least one light-emitting member (3) electrically connected to the printed circuit board (2). The printed circuit board (2) has a main portion (4) designed to be mounted behind the light guide plate (9), and a secondary portion (6) extending the main portion (4) while also being angularly positioned in such a manner as to form an angle with said main portion (4) so as to be situated facing the edge face of the light guide plate (9), and the light-emitting members (3) are carried by the secondary portion (6). The invention is applicable to flat screens.
Abstract:
The invention relates to a backlit motor vehicle gauge such as a speedometer or a revolution counter, which gauge has a wall provided with translucent graduations disposed over a circular arc, one or more light-emitting elements (16) carried by a support plate (13), and a light guide (18) interposed between the support plate (13) and the graduated wall so as to diffuse the light emitted by the light-emitting elements (16) towards a back face of the graduated wall in order to illuminate all of the graduations. According to the invention, the light guide (18) is mounted to pivot IO about an axis (AX) passing through the center of the circular arc while having its position servo-controlled, and said light guide (18) carries a spot lighting member (28) situated radially at the same level as the circular arc so as to highlight a portion of the region carrying the graduations. The invention is applicable to gauges designed to equip motor vehicles.
