Abstract
An illuminating magnifier has an annular housing with an underside, an inner edge defining an opening and an outer edge. A magnifying lens fills the opening, which lens has an optical axis. Light emitting diodes are distributed about the axis at the underside of the housing, each diode, when energized, producing a relatively wide angle conical light beam with a central hot spot cone which can illuminate a viewing field below the lens. Special mounting surfaces at the housing underside aim the diodes in the diode array at selected angles relative to the lens axis so that the conical light beams therefrom overlap and all points in the viewing field are illuminated by the light beam from each diode and a center region of that field around the axis is illuminated by the hot spot cones of all the diodes.
