Illuminating magnifier apparatus

摘要

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.

主权项

1. A magnifier housing apparatus for illuminating and magnifying a specimen, the apparatus comprising:
an inner edge defining an opening with a central axis; an underside, wherein the underside comprises:
a plurality of thermal stanchion pairs formed integrally with the magnifier housing, wherein each of the plurality of thermal stanchion pairs is substantially a cuboid shape and comprises:
a first rounded vertical side;a second rounded vertical side disposed substantially opposite the first rounded vertical side;a top surface disposed between the first rounded vertical side and the second rounded vertical side;wherein the first rounded vertical side of the thermal stanchion is narrower (heel) than the second rounded vertical side (toe); andwherein each of the plurality of thermal pedestal pairs is passively adapted to dissipate heat from the top surface heel side to the magnifier housing and the second rounded vertical side (toe) side.
