Abstract

An apparatus for distributing light from a primary light source e.g. an incandescent bulb 2, to a number of remote locations 7. The apparatus has a number of reflective surfaces, e.g. mirrors 3 that reflect light emitted from the primary light source 2 to the remote location 7. Light guides 5 may be used to channel the light to the remote location 7.

Description

AN APPARATUS FOR DISTRIBUTING A LIGHT SOURCE
The present invention relates to an apparatus for distributing a primary light source to a plurality of remote secondary light sources.
It is often desirable, at night, to illuminate a number of areas in, for example, an open space, such as a garden during a gathering or a party.
Conventionally, this is achieved by providing various light sources, usually in the form of light bulbs, at spaced intervals within the open space. I0
A disadvantage of such an arrangement is that electrical cables have to extend between all the light sources. Also it is inconvenient for one or more of the light sources to fail when most needed.
To this end there is provided according to the present invention an apparatus for distributing a primary light source to a plurality of remote secondary light sources, comprising a plurality of reflective surfaces so disposed that in use light emitted from the primary light source is reflected via at least some of the reflective surfaces to the remote light sources.
The primary light source may be located within a body having internal wall regions which comprise at least one reflective surface.
The body may comprise a sphere.
The or each reflective surface may communicate with the remote light sources via a plurality of elongate passages each provided with at least one internal reflective surface.
The or each reflective surface may comprise a mirrored layer.
The apparatus may comprise a plurality of reflective surfaces, each of which is so spaced from an adjacent reflective surface as to provide multiple reflections of light emitted from the primary light source.
Each reflective surface may be a mirrored surface provided on an individual element.
The apparatus may comprise a continuous reflective surface on which light from the primary light source may be reflected a plurality of times.
An embodiment of the present invention will now be described by way of example and with reference to the accompanying drawing, the single figure of which shows a primary light source located in a container and communicating with a plurality of spaced secondary light sources.
The drawing shows a container in the form a spherical hollow body 1.
Within the body is situated a primary light source such as an incandescent light bulb 2. The light source may emit either white or coloured light and may receive its power from the domestic mains. 3.,
Adhered to the internal wall surfaces of the body 1 are a plurality of mirrors 3 which reflect light emanating from the bulb 2.
The body 1 is provided with a plurality of holes 4, from each of which extends a tubular passage 5. Located within the tubular passages are a plurality of reflective elements such as mirrors 6, only some of which are illustrated in the drawing.
The opposite end of each tubular passage 5 communicates with a secondary light source 7. Each secondary light source 7 may comprise a spherical body 8 provided with a plurality of holes 9.
In use, light from the primary light source 2 is reflected a plurality of times on the internal surface of the body 1 by the mirrors 3 and is distributed along the tubular passages 5 and again reflected by the mirrors 6. Thereafter, the distributed light passes through the holes 9 in the bodies 8 to illuminate the area around each body 8. 4.*

Claims (8)

  1. Claims 1. An apparatus for distributing a primary light source to a plurality of remote secondary light sources, comprising a plurality of reflective surfaces so disposed that in use light emitted from the primary light source is reflected via at least some of the reflective surfaces to the remote light sources.
  2. 2. An apparatus as claimed in claim 1, wherein the primary light source is located within a body having internal wall regions which comprise at least one reflective surface.
  3. 3. An apparatus as claimed in claim 1 or claim 2, wherein the or each reflective surface communicates with the remote light sources via a plurality of elongate passages each provided with at least one internal reflective surface.
  4. 4. An apparatus as claimed in any one of the preceding claims, wherein the or each reflective surface comprises a mirrored layer.
  5. 5. An apparatus as claimed in any one of the preceding claims, comprising a plurality of reflective surfaces, each of which is so spaced from an adjacent reflective surface as to provide multiple reflections of light emitted from the primary light source. 5..
  6. 6. An apparatus as claimed in any one of the preceding claims, wherein each reflective surface is a mirrored surface provided on an individual element.
  7. 7. An apparatus as claimed in any one of the preceding claims, comprising a continuous surface on which light from the primary light source may be reflected a plurality of times.
  8. 8. An apparatus for distributing a light source, substantially as herein described with reference to the accompanying drawing.
