An adjustable reflector device is disclosed. The device consists of an adjustable double parabolic reflective skin with an adjustable lamp mount, incorporating a V-shaped perforated heat shield, attached. The two part reflective skin forms a double parabolic shape when flexed back against a reinforced spine. This flexible shape is secured by lengthwise adjustable chain retainers attached a both ends of the skin. The lamp mount slides onto a pair of threaded bolts secured to the skin and adjustment is achieved by tightening or loosening the appropriate nuts. The heat shield slides onto the lamp fitting and is positioned appropriately to deflect incident heat and light. This device can be used to provide variable conditions of artificial illumination.

DETAILED DESCRIPTION The present invention seeks to provide an adjustable reflecting device which substantially or at least ameliorates the disadvantages of the prior art.
According to a first aspect of the present invention there is disclosed a light fitting comprising a lamp receiving fixture having first and second opposite sides, and a reflector means, the reflector means being mounted to said first side of the lamp receiving fixture to produce a beam of light from said light fitting when said lamp receiving fixture contains an illuminated lamp, wherein said light fitting also includes a heat shield mounted to said second side of said lamp receiving fixture and in said beam of light, said heat shield having at least one surface facing said reflector means and directly receiving light from said lamp incident on said surface, each said surface being angled relative to said lamp receiving fixture to prevent light from said lamp being reflected towards said lamp and reflector means, and also having a plurality of apertures therein through which some of the light emitted by said lamp can pass.
According to a second aspect of the present invention there is disclosed a method of shielding a beam generated from a light fitting comprising a lamp receiving fixture having first and second opposite sides and a reflector means, the reflector means being mounted to said first side of the lamp receiving fixture to produce said beam from said light fitting when said lamp receiving fixture contains an illuminated lamp, said method comprising the step of mounting a heat shield to said second side of said lamp receiving fixture and in said beam of light, said heat shield having at least one surface facing said reflector and directly receiving light from said lamp incident on said surface, each said surface being angled relative to said lamp receiving fixture to prevent light from said lamp being reflected towards said lamp and reflector means, and also having a plurality of apertures therein through which some of the light emitted by said lamp can pass
