摘要:
A programmable signal light which can be used as a flashlight, an alarm light, a signal light, or a lantern. The light has a battery, a circuit board, a three-position switch, and a thumbwheel which can be set for any period up to ninety-nine hours. The light remains off until the predetermined number of hours has elapsed, then turns on.

A method of extending the useful life of one or more conventional DC batteries in a battery-powered device. The method involves use of at least one dry cell DC battery, at least one metal blank, and a battery-powered apparatus having a battery compartment and an extension housing. At least one dry cell DC battery is placed inside the battery compartment of the battery-powered apparatus. At least one metal blank is then placed in the extension housing for completing an electrical circuit between first and second contacts of the battery-powered device. Using a voltmeter, the voltage of one of the dry cell DC batteries is tested. If the voltage of the dry cell DC battery is below a threshold voltage level required for the battery-powered apparatus, at least one metal blank is then replaced with a partially-charged battery.

A slide focus flashlight has a container with an aperture therein, a lamp disposed within the container, a reflector disposed within the container, and an actuator disposed in the opening of the container for sliding therein and having a first angled surface. A conductive shaft is disposed within the container, and a slide interface is coupled to the conductive shaft. The slide interface has a second angled surface for sliding against the first angled surface of the actuator. A power switch is provided for selectively energizing the lamp. The slide interface, actuator and power switch allow for single-handed focusing and energizing of the flashlight.

The disclosed invention relates to light sources such as battery-powered flashlights and lanterns. Tailcap, battery housing, or head assemblies for light sources are formed from electrically conductive plastic. Those assemblies, or the components of such assemblies, form electrically conductive elements in the electrical circuit of, and may impart shape and structural integrity to, the light source.

A battery-powered apparatus for holding and energizing an electric transducer, includes a hand-held battery housing carrying the transducer mount, and first and second internal battery contacts. A first external battery charge terminal is on the transducer mount, and a second external battery charge terminal is on a part of the battery housing, such as its end cap. A double-throw switch has a common element electrically connected to an internal battery terminal contact, has a first switched contact leading to a first terminal of the electric transducer, and has opposite second switched contact electrically connected to an external battery charge terminal. If there are two electric transducers, they may be a part of a light source comprising a reflector, a first electric lamp having a filament at its focal point, and a second electric lamp extending into that reflector beside the first electric lamp.

A multi-function container includes a housing, a closure and an exterior light source. The container has a first interior portion adapted to hold small items. The closure is used to cover the first interior portion of the housing and to contain the small items in the first interior portion of the housing. The housing also has a second separate interior portion adapted to hold a battery. The light source is operatively coupled to the second interior portion to receive power from the battery, upon the battery being held within the second interior portion. Thus, the multi-function container may serve as a container and/or a flashlight. The multi-function container may also include a key ring which is coupled to an exterior surface of the closure, and may also include a clock coupled to the side of the housing.
摘要:
A focusable flashlight comprising a cylindrical tube for containing a battery, a head combined with the front end of the tube by means of a spring stop, a lamp holder and a spring pusher, the head functioning as a switch by being movably screwed to change the distance between the lamp holder and the front end surface of the tube in turning on or off electric power from the battery and at the same time light focusable by means of a transparent lens and a light reflector fixed at the front of the head.
摘要:
A lighting assembly for use in a cigaret lighter shell. The lighting assembly comprises an insulative case for housing a power supply, such as batteries, and conductors for establishing an electrical circuit that includes the batteries, the conductors, and a light bulb and that does not rely on conductivity of the shell. An adjustable reflector and lens may be provided to focus and direct the beam generated by the bulb. One conductor is moved into contact with another of the conductors in response to opening of the lid of the shell to close the electrical circuit to turn the flashlight on. One of the conductors is moved out of contact with another in response to closing of the lid to turn the flashlight off. One of the conductors is positioned for preventing its contact with another conductor when the lighting assembly is removed from the shell so that it is turned off. One conductor may be manually positioned or locked in position so that it is not in contact with another conductor so that the flashlight is turned off while the lid is open.
摘要:
A renovated flashlight includes a head means and a cylindrical battery compartment. The head means is composed of a lid, a reflecting means, a spring means, and a conducting means. The reflecting means has a hollow body at bottom portion adopted to receive the spring means, and the conducting means therein. A longitudinal slot is formed at one side of the hollow body for a negative conducting plate to extend therefrom.
