Abstract
An adjustable reflector device is disclosed. The device consists of an adjustable double parabolic reflective skin (1,2) with an adjustable lamp mount (12), incorporating a V-shaped perforated heat shield (17), attached. The two part reflective skin (1,2) forms a double parabolic shape when flexed back against a reinforced spine (3). This flexible shape is secured by lengthwise adjustable chain retainers (4) attached at both ends of the skin (1,2). The lamp mount (12) slides onto a pair of threaded bolts (6,7) secured to the skin and adjustment is achieved by tightening or loosening the appropriate nuts (15,16). The heat shield (17) slides onto the lamp fitting (18) and is positioned appropriately to deflect incident heat and light. This device can be used to provide variable conditions of artificial illumination.
Claims14
A lamp reflector with adjustable curvature comprising
- a pair of resilient sheet members each having a reflective surface;
- connecting means for connecting said sheet members together along a common spine so that the sheet members have unflexed positions wherein said reflective surfaces are transverse to each other, each sheet member being adapted to be flexed from said unflexed position to a fully flexed position which forms the corresponding reflective surface into an inside curve with maximum curvature, and
- adjustable retaining means connected to said sheet members for retaining said sheet members at a plurality of a selected flexed positions between said unflexed and fully flexed positions.
A lamp reflector with adjustable curvature comprising
- a pair of resilient sheet members, said sheet members having reflective surfaces and being connected so that, when in an unstressed condition, said sheet members are disposed at an angle relative to each other, and when flexed away from said angle, the reflective surface of each sheet member assumes a parabolic shape and
- means connected to said sheet member for adjustable flexing said members away from said angle.
