Description
LIGHTING ARRANGEMENT
This invention relates to lighting arrangements.
According to the present invention there is provided a lighting arrangement comprising a bulb support, a shade and a holder which is attached to the shade and which receives the bulb support by a pushfit.
Preferably the shade is inflatable and is sealingly attached to the holder. Conveniently the shade is made from transparent or semi-transparent
PVC.
In one arrangement the holder is in the form of a closed recess, circular in cross-section, the bulb support being retained in the recess by the clamping action caused by inherent elasticity of the holder which is forced to expand slightly on insertion of the bulb support and by friction between the bulb support and the holder
Embodiments of the present invention will be described below in more detail. The description makes reference to the accompanying diagrammatic drawings in which:
Figure 1 is a part sectional exploded view of an arrangement according to the present invention,
Figure 2 is a part sectional view of the assembled arrangement of figure 1.
In the figures there is shown a lighting arrangement 10 comprising a PVC shade 11 which is transparent or semi-transparent. In this arrangement the shade 11 is inflatable by means of a suitable inlet which is not shown. The shade is sealingly attached to a transparent or semi-transparent PVC holder 12 which is circular in cross-section and generally conical along its length. The sealing attachment is by heat sealing, although adhesive could be used.
The holder 12 receives a light bulb support 13 which has an outermost wall 14 which is circular in cross-section. The dimensions of the upper portion 15 of the holder 12 and the wall 14 are such that the bulb support is a push-fit in the holder 12 and is securely retained therein by the clamping action caused by the elasticity of the holder 12 which is forced to expand slightly on insertion of the bulb support 13. Friction between the two parts may also assist retention.
The bulb support 13 supports a bulb 16 in a position determined by the position of a knot 17 in the wire 18 leading from the bulb 16. When the bulb support 13 is inserted in the holder 12 the bulb 16 is supported towards the bottom of the holder 12.
It will be appreciated that the push-fit connection is uncomplicated and is relatively cheap and simple to produce. The push-fit avoids the use of bayonet or screw-fit connections of the bulb support to the shade.
The inflatable nature of the shade ensures that the shade is very portable as it can be rolled or folded when the air has been removed. This makes the lighting arrangement particularly suitable for use with flashlights provided of course the flashlights can be adapted to have their bulbs arranged as above, i.e. operational at a distance from the main body of the flashlight but connected by the wire 18. It will be clear that this is not the sole application, others being clearly possible.
Also the bulb support 12 can be quickly and easily disconnected from one shade 12 and attached to another shade. Disconnection is simply a matter of pulling the bulb support 12 from the shade, connection being a simple push-fit as described above.
The shades 11 can of course be of any shape or colour and may incorporate pictures and/or graphics.
Also various adornments could be applied to the outside if desired.
The material of manufacture stated above is
PVC, but other suitable materials would of course be suitable for the shade, the holder and the bulb support. It is also possible that the shade 11 may not be inflatable, but could still incorporate the holder/bulb support arrangement as described above.
In addition, other methods of spacing and supporting the bulb 16 relative to the bulb support 13 are readily envisaged. For example, the bulb 16 could be a push-fit in the bulb support or the knot could be replaced by some form of disc which abuts the bulb support 13 when the bulb 16 hangs free. When the bulb is supported by the wire, it is possible to use any bulb which fits inside the holder 12. There is then no requirement for the bulb 16 to be of a certain size or connection to fit the bulb support 13.
It will be appreciated that alternatively or in addition the wall 14 of the bulb support 13 may contract elastically somewhat on insertion into the holder 12 so that an elastic wedging action is produced to retain the support 13 in the holder 12.
Claims (6)
1) A lighting arrangement comprising a bulb support,
a shade and a holder which is attached to the
shade and which receives the bulb support by a
push-fit.
2) A lighting arrangement as claimed in claim 1
wherein the shade is inflatable and is sealingly
attached to the holder.
3) A lighting arrangement as claimed in claim 1 or
claim 2 wherein the shade is made from
transparent or semi-transparent PVC.
4) A lighting arrangement as claimed in any one of
claims 1 to 3 wherein the holder is in the form
of a closed recess, circular in cross-section,
the bulb support being retained in the recess by
said push-fit.
5) A lighting arrangement as claimed in claim 4
wherein said push-fit effects a clamping action
caused by the inherent elasticity of the holder
which is forced to expand slightly on insertion
of the bulb support and/or by friction between
the bulb support and the holder.
6) A lighting arrangement substantially as
hereinbefore described with reference to and as
illustrated in the accompanying drawings.
