Definitions
- the invention relates to a luminaire having a holder for a capless miniature incandescent lamp which comprises connection wires projecting outwards on one side for the connection to a plate which is provided with contact elements.
- Pisello-lamps For instrument and dial lighting, for example, in wireless sets, very small miniature incandescent lamps having ninepin-shaped envelopes, so-called Pisello-lamps, are used. Such Pisello-lamps have no ribs with which they can be locked in a holder. It is the object of the invention to provide a holder for such lamps which, as compared with the said known luminaires, is much simpler and cheaper of construction and in which the fact that the connection wires of Pisello-lamps are very thin and, mechanically, can be loaded only restrictedly, has been taken into account.
- the holder comprises two laterally projecting studs around which the connection wires'of the lamp are wound and which are connected to the contact elements of the plate. So in this case the connection of the lamp in the holder occurs by means of the connection wires of the lamp in that said connection wires are wound around two laterally projecting studs. Upon securing the holder to a plate, the studs wound in this manner are contacted with the contact elements present on said plate.
- the luminaire according to the invention is characterized in that the contact-elements of the plate are in the form of leaf springs below which the studs of the lampholder (around which the connection wires of the lamp are wound) are slid.
- the leaf springs serve not only for making an electric contact but also for securing the lampholder to the plate.
- said plate may also comprise a recess in which a projection of the holder engages in a locking manner.
- the plate may be provided, near the studs, with metal contact faces which replace the above-mentioned leaf springs.
- FIG. 1 is a perspective view ofa luminaire according to the invention in which the connection of the holder to the plate as well as the electric contact has been realized by means of leaf springs.
- FIG. 2 shows another embodiment of the luminaire according to the invention in which the electric contact has been realized by means of contact faces.
- the luminaire serves to receive a Pisello-lamp l which is provided in a holder'2 of a synthetic material or the like.
- the holder 2 consists of a member 3 having two upright supports 4 between which the wide end of the lamp 1 is incorporated.
- the member 3 comprises two slots 6 which extend in the axial direction of the connection wire 5 of the lamp and parallel to the edge of the holder up to the centre of the holder.
- the holder 2 comprises two laterally projecting studs 7.
- connection wires 5 are then introduced into the slots 6, stretched taut and then routed to the laterally projecting studs 7 to be secured there by winding around the studs 7.
- the ends of the connection wires 5 of the lamp wound around the studs are denoted by 8.
- the holder 2 with the lamp 1 is now to be secured to a plate 9
- two leaf springs 10 which serve as contact elements are provided on the plate 9 and below said leaf springs the studs 7 of the lampholder 2 (around which the connection wires 5 are wound) are slid.
- the leaf springs 10 serve as contact elements and for the mechanical connection of the holder 2 to the plate 9.
- connection of the holder 2 to the plate 9 may be carried out by means ofa rotary movement of the holder 2, the studs 7 being slid below the leaf springs 10.
- the front support 4 of the holder 2 comprises a downwardly directed projection 11 which has a T-profile at its end. Furthermore the plate 9 comprises a slot-like recess 12 in which the projection 11 of the holder 2 engages in a locking manner as a result ofwhich a good connection of the holder 2 to the plate 9 is ensured.
- the contacting in this case is carried out by means of two strip-shaped contact faces 13, for example in the form of printed conductors, which are provided on the plate 9 in the region of the studs 7 around which the connection wire ends 8 are wound.
- a luminaire having a holder and a capless miniature incandescent lamp, an insulating plate having contact elements disposed thereon and carrying said' holder, said holder comprising two upright supports cooperatively dimensioned and configured for holding said lamp, connection wires projecting outwards on one side of said lamp and engaging said contact elements on said insulating plate, said holder further comprising two radially projecting studs around which the connection wires of the lamp are wound and which are connected to the contact elements of the plate.
