Abstract
Abstract An apparatus and method for forming a conical or domed ring light having a plurality of light sources arranged at a desired angle with respect to an optical axis. Some of the dimensions of the illumination apparatus are first determined and, then using the appropriate formulas, the remaining dimensions of the circuit board are calculated. Thereafter, the calculated dimensions are employed to cut, from a planar flexible circuit board, the desired arcuate section(s). The light sources are then installed at desired locations on a first surface of the flexible circuit board and are each coupled to a common electrical connector, having one or a plurality of power sources, to facilitate supplying electrical power to each one of the light sources. The circuit board is then folded into a conical or domed configuration, with the light sources facing inward, and each abutted end and lateral surfaces of the folded circuit board is suitably secured or fastened to one another to permanently retain the flexible circuit board in its folded state.
