Abstract
A flat card shaped illuminator with an on/off switch integrally formed therein. The flat card shaped light is adapted to a variety of uses and the on/off switch may be momentary or latching. One or more LEDs may be incorporated therein and the batteries may be removable.
Claims26
A flat illuminator comprising:
- a flat substantially planar plastic body with a front face, a back face, and with an edge thickness less than about 3.5 millimeters;
- one or more light emitting diodes (LEDs) affixed to, or within, the substantially planar plastic body;
- a battery power supply with a positive and negative terminal mounted within said plastic body which does not protrude beyond the edge thickness and with one of the terminals conductively linked to the one or more light emitting diodes;
- a horizontal pressure switch which comprises;
- a flexible switching arm extending from the plastic body which does not exceed the thickness of the plastic body;
- and
- a series of contacts, at least one of which of is affixed to the flexible switching arm opposite another on the plastic body, whereby the battery terminal, not connected to the one or more light emitting diodes, can be connected by the displacement of the flexible switching arm and contacts affixed thereon, to the one or more light emitting diodes.

A flat illuminator comprising:
- a flat substantially flat and rectangular plastic body with an edge having a thickness between about 1.0 mm and about 3.5 mm;
- one or more light emitting diodes (LED) affixed to, or within said edge which do extended or protrude beyond said edge thickness with an anode and cathode contact extending;
- a lens formed integrally as part of said one or more light emitting diode which is at a fan angle of between 5 and 15 degrees;
- a 6-12 volt button battery power supply mounted within said plastic body which does not protrude beyond said edge thickness;
- an on/off switch further comprising:
- a first switch contact which is conductively linked to a first battery contact on the positive terminal of said battery power supply;
- a second switch contact which is conductively linked to said cathode contact of said one or more light emitting diodes;
- a flexible leg supporting said second switch contact, whereby the movement of said flexible leg places the first and second switch contacts together;
- and,
- a second battery contact against the negative terminal of said battery power supply and conductively linked to said anode contact of said one or more light emitting diodes.
7 more elements
A flat credit card shaped illuminator comprising:
- a substantially planar plastic body with a substantially rectangular bottom face;
- a side wall formed around said bottom face with a thickness less than about 3.5 mm, forming an open cavity;
- one or more light emitting diodes (LED) affixed to said plastic body with an anode and a cathode contact extending into the open cavity;
- a button battery power supply mounted removably within the plastic body;
- a first switch contact conductively linked to the positive terminal of said button battery power supply:
- a second switch contact conductively linked to the cathode contact
- a flexible switching arm extending from the plastic body supporting the second switch contact, whereby the movement of said flexible arm momentarily places the first and second switch contacts together;
- the anode contact conductively linked to the negative terminal of the button battery power supply;
- a flat cover which closes off the open cavity.
