An article of jewelry consists of first and second lengths of electrically conductive wire with a light emitting diode connected across a first set of the free ends of the wire lengths. A restraining diode is connected across the lengths of wire in close proximity to but inwardly of the first set of free ends. The restraining diode is electrically connected in opposition to the current flow through the light emitting diode. A linear integrated oscillator circuit and a low voltage power source are connected across the other set of free ends of the lengths of wire to provide the flashing circuit for the light emitting diode.
A lighting system for toys such as floating disc toys wherein a plurality of point light sources are spaced apart in the plane of movement and are energized intermittently by a battery through a circuit which utilizes a single multi-NAND gate chip and finger resistance for switching.
Light emitting electronic jewelry, an earring for example, includes an earring post having a light emitting diode supported thereon. The diode is connected in an electrical circuit including a battery means. In one form of the invention, the electrical circuit includes an integrated circuit and a capacitor electrically connected between the integrated circuit and light emitting diode such that the diode is caused to flash on and off. In another form of the invention, the electrical circuit includes a mercury switch electrically connected between the diode and battery so as to make and break the electrical connection therebetween in response to movements of the wearer. The battery and electrical circuit components may be supported within a casing suspended from the earring post.
The present invention provides an illuminating apparatus for ornamental elements such as in an illuminated necklace, an illuminated belt or the like, which includes a plurality of lamps to illuminate more than one lamp housing which simulates a pendant or the like. A battery assembly is provided in one of the lamp housings to power the circuit of the illuminating apparatus.
An aiming post light for artillery and mortar operations at night wherein an ordinary GI flashlight may be used, without modification, as a post light when mounted on a support and wherein its original ordinary lightbulb is replaced with a novel bulb of same base outer configuration in which the bulb has encapsulated solid state circuitry to provide a blinking and/or steady light emitting diode (LED) as the light source. Depending upon the particular LED and circuitry selected, the light may be continuous or intermittent and may be a selected color. In one embodiment several options are available when using a single bulb.
Four red light emitting diodes are embedded in a synthetic resin encapsul. Two diodes in each of two pairs are connected in parallel and the two pairs are connected in series with a resistance, a blocking diode, and an on-off switch. A fifth diode which emits yellow light when energized is connected in series with a resistance, a blocking diode, and a brake-actuated switch.
