Abstract

A hand-held illuminated eye loupe includes an open top and bottom housing with an internal magnifying lens. A light source assembly is removably coupled to one side of the housing. The light source assembly includes a hollow chassis configured to retain a LED which provides focused light beam adjacent to the open bottom of the housing. The LED has positive and negative terminal wires. Four cell batteries are operatively stacked between the negative terminal wire and a connector plate. A light switch assembly is coupled to the chassis and configured to embed a portion of the positive terminal wire. The embedded terminal wire includes a curved end which makes electrical contact with the connector plate to turn the LED on when the switch is pushed toward the LED. The curved end pulls away from the connector plate to turn the LED off when the switch is pushed away from the LED.

Dependent claims

An illuminated eye loupe, comprising:

a hollow housing configured to receive and retain internally at least one magnifying lens;
and
a light source assembly removably coupled to one side of said hollow housing, said light source assembly comprising:
at least one LED (Light Emitting Diode) configured to provide focused light beam adjacent to an area being viewed through said at least one magnifying lens, said at least one LED including a positive terminal wire and a negative terminal wire;
at least one power source operatively coupled to said negative terminal wire;
at least one electrical connector plate operatively coupled to said at least one power source;
a light switch assembly configured to embed a portion of said positive terminal wire, said embedded terminal wire including a curved end which makes electrical contact with said at least one electrical connector plate to turn said at least one LED on when said light switch assembly is pushed toward said at least one LED, said curved end pulling away from said at least one electrical connector plate to turn said at least one LED off when said light switch assembly is pushed away from said at least one LED.

4 more elements

An illuminated eye loupe, comprising:

a main housing having a substantially truncated cone shape, said main housing configured to receive and retain internally a first magnifying lens between an open top and an open bottom, said open bottom being configured for viewing at least one area in need of optical magnification;
a light source assembly removably coupled to one side of said main housing, said light source assembly comprising:
a substantially elongated chassis with a hollow interior;
a LED (Light Emitting Diode) being retained within said hollow chassis, said retained LED being configured to provide focused light beam adjacent to said open bottom of said main housing, said LED fitted with a positive terminal wire and a negative terminal wire;
a plurality of low voltage power sources being retained within said hollow chassis, said retained power sources being operatively disposed over said negative terminal wire;
a connector plate being retained within said hollow chassis, said retained connector plate being operatively disposed over said power sources;
a light switch assembly operatively coupled to said chassis and configured to embed a portion of said positive terminal wire, said embedded terminal wire including a curved end which makes electrical contact with said connector plate to turn said LED on when said light switch assembly is pushed toward said LED, said curved end pulling away from said connector plate to turn said LED off when said light switch assembly is pushed away from said LED;
and
an auxiliary housing configured for insertion into said main housing via said open bottom, said inserted auxiliary housing fitted internally with a second magnifying lens to alter the optical magnification power of said first magnifying lens, said second magnifying lens being recessed relative to an outer lip of said auxiliary housing.
