DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention has as its subject an assembly of a lamp and a support designed, more particularly, to be inserted into a printed circuit board or the like.
Lamp supports and lamps of this type have been known per se for some time. They are used in particular in the automobile industry, in order to equip the dashboards of vehicles. Of course, their application is not strictly limited to this field.
Although the known products generally give satisfactory results, it became apparent that it was desirable and possible to improve their performance both in terms of their service life and the quality of the lighting provided.
SUMMARY OF THE INVENTION
The present invention therefore has the object of providing such an improved assembly of a lamp and of its support. The invention also has as its object a specific structure of an electrical connection capable of being produced by automated winding.
According to the invention an assembly of a lamp and of its support is provided which can be inserted into a printed circuit board or the like, characterised in that the lamp is disposed on the support perpendicular to the axis along which support is snapped into the board, so that the lamp (and also the filament) is parallel to the board in its position of use.
In all of the known devices of the prior art and of this known field, the lamps are parallel to the main axis of the support and to the axis along which the support is snapped into the board.
The invention will be better understood with the aid of the description of an embodiment given as a nonlimiting example with reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a side elevation view of a lamp support and of a lamp according to the invention;
FIG. 2 is an inverted plan view of FIG. 1;
FIG. 3 is a plan view of FIG. 1;
FIG. 4 is a sectional view along A--A of FIG. 1;
FIG. 5 is a plan view of a specific imprint for mounting the support of the invention in a printed circuit board.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Reference is made first to FIG. 1.
FIG. 1 shows the support (1) and the lamp (2) disposed in a horizontal position. The support comprises a table (3) for reception of the lamp which also serves as a reflector. The lamp is held in position by a clip (4) or by any other means.
The electrical connectors, shown in FIGS. 2 and 3, are formed as a wire (5) which extends toward the bottom of the support and which is wound at each of its ends onto the free ends of a resilient support beam (6). The windings may be executed in both directions around the beam, possibly with a change of direction by an angle reverse pin (7). The wires can, if desired, be wound between one or two flanges (8, 9) formed integrally with the beam, and may be securely attached to the beam by deformation (shown at (18) in FIG. 4) of at least one flange (e.g., by addition of material or by ultrasonic welding). For better stability against vibrations and flow, the beam (6) may incorporate a metal insert (10).
Mounting will be effected in a printed circuit board at the level of the plane (11), with snap catches (12, 13) which come into abutment with the bottom of the board (14). The imprint (15) shown in FIG. 5 permits a simple snapping home, without rotation. However, it would also fall within the scope of the invention to provide a blocking connection by rotation (as is the case for most supports of the prior art).
This novel structure brings manifold advantages which, in a non-exhaustive manner, are discussed below.
1. Because the lamp is flat with respect to its support (and therefore to the board), the following benefits are drawn: of the support. For this several possibilities are envisaged:
Each of these actions contributes to a gain in lighting, which may be up to four-fold. Such a gain enables the service life of the lamp to be increased as a result of lower stresses on it, or as a result of reduced energy levels. An improvement of the luminance/watt ratio is thus obtained.
Moreover, the overall
