Abstract
A miniature, self-powered, user-powered lighting device, employing mechanical energy storage and incorporating miniature lighting elements which are illuminated on-demand for a limited duration for backlighting or illumination purposes without the need for a battery or other electro-chemical storage device. The device comprising a manual spring loading mechanism, a spiral spring, a manual trigger mechanism, a transmission for increasing the rotational speed, a miniature generator, and at least one light source.
Claims21
A wristwatch having a miniature, user-powered electrical generating device incorporating therein, the wristwatch having a watchband, employing mechanical energy storage and incorporating miniature special effects elements which are activated on-demand for a limited duration without the need for a battery or other electro-chemical storage device, the wristwatch comprising
- a. a spring,
- b. a manual spring loading mechanism mechanically coupled to the spring,
- c. a manual trigger mechanism mechanically coupled to the manual spring loading mechanism,
- d. a transmission,
- e. a miniature generator, and
- f. one or more special effect element, the spring mechanically coupled to the transmission for increasing a rotational speed, the transmission mechanically coupled to the miniature generator the miniature generator electrically coupled to the one or more special effect element,
- wherein the manual spring loading mechanism is further mechanically coupled to the spring, the spring being releasable by a user via the manual trigger mechanism to actuate the one or more special effect element, the spring being mechanically coupled to the transmission which is in turn rotationally coupled to the miniature generator, the miniature generator being electrically coupled to the one or more special effect element to provide a special effect, and the miniature generator providing sufficient electrical energy to activate the one or more special effect element for a given time period.
A miniature, user-powered electrical generating device incorporated therein, employing mechanical energy storage and incorporating miniature special effects elements which are activated on-demand for a limited duration without the need for a battery or other electro-chemical storage device, the device comprising
- a. a spring,
- b. a manual spring loading mechanism mechanically coupled to the spring,
- c. a manual trigger mechanism mechanically coupled to the manual spring loading mechanism,
- d. a transmission,
- e. a miniature generator, and
- f. one or more special effect element, the spring mechanically coupled to the transmission for increasing a rotational speed, the transmission mechanically coupled to the miniature generator, the miniature generator electrically coupled to the one or more special effect element,
- wherein the manual spring loading mechanism is further mechanically coupled to the spring, the spring being releasable by a user via the manual trigger mechanism to actuate the one or more special effect element, the spring being mechanically coupled to the transmission which is in turn rotationally coupled to the miniature generator, the miniature generator being electrically coupled to the one or more special effect element to provide a special effect, and the miniature generator providing sufficient electrical energy to activate the one or more special effect elements for a given time period, wherein further the device is incorporated into a timepiece comprising electrical circuitry in which the miniature generator generates an alternating current and in which there are at least two light sources which are light emitting diodes connected in parallel in opposing senses such that positive components of an electrical signal illuminate one diode and negative components of the electrical signal illuminate the other diodes.
