ABSTRACT:
A mobile light panel stand supports a light panel suited to treat humans who are in need of exposure to light in a manner known as light therapy. The stand has two pair of hinged legs. Each pair of legs has a brace member to provide a solid two-legged assembly. The two two-legged assemblies are connected by collapsible braces which allow the device to fold into a narrow posture for passage through doorways. The base of the opened assembly has an anti-tipping wide stance for use by hospitals where patients may lean on the device for support. One set of legs has an upper extension which supports the light panel between the two two-legged assemblies via adjustable nuts and bolts. The light panel can be tilted by adjusting the adjustable nuts. In the preferred embodiment the angle between the front and rear H shaped support legs is adjustable between zero and 180 degrees. This feature coupled with a smaller width light panel and H frame stance and wheel braces makes the device suitable for mechanics' work areas where a low stance of the light panel can light a brake repair job. The light stand itself can be adjusted up and down along its support legs.
