Abstract
A Shabbat bulb and a related method is provided allowing control of illumination without electrical intervention by a person observing strictures of Shabbat orthodox Jewish law. The bulb includes a housing covering an electrically operated light source. A blackout mechanism is attached to but easily separable from the housing and has no operating connection with electrical circuitry. The mechanism includes a disc having at least one disc aperture through which light from the light source is transmitted; and an arm projecting radially outward from the disc. Manual movement of the arm from an open position to a closed position respectively allows full or totally no illumination to exit the bulb via the disc.
Claims16
A Shabbat bulb which allows control of illumination without electrical intervention by a person observing strictures of Shabbat orthodox Jewish law, the bulb comprising:
- a housing covering an electrically operated light source, the housing having a power connecting end and an oppositely arranged illumination transmitting end, both ends being aligned along a common axis, and a threaded screw formed externally on the housing adjacent the power connecting end for connection into an electrical socket;
- a blackout mechanism separable from the illumination transmitting end and having no operating connection with electrical circuitry, the mechanism comprising:
- an outer ring oriented around the common axis, a slot formed on a periphery to the outer ring;
- a disc mounted within the outer ring including at least one disc aperture through which light from the light source is transmitted;
- and
- an arm projecting radially outward from the disc and projecting through the slot, manual movement of the arm slideably along the slot from an open position to a closed position respectively allowing full or totally no illumination to exit the bulb via the disc.
A method for non-electrically controlling illumination from a light bulb, the method comprising:
- obtaining a Shabbat bulb which comprises:
- a housing covering an electrically operated light source, the housing having a power connecting end and an oppositely arranged illumination transmitting end, both ends being aligned along a common axis, and a threaded screw formed externally on the housing adjacent the power connecting end for connection into an electrical socket;
- a blackout mechanism separable from the illumination transmitting end and having no operating connection with electrical circuitry, the mechanism comprising:
- an outer ring oriented around the common axis, a slot formed on a periphery to the outer ring;
- a disc mounted within the outer ring including at least one disc aperture through which light from the light source is transmitted;
- and
- an arm projecting radially outward from the disc and projecting through the slot, manual movement of the arm slideably along the slot from an open position to a closed position respectively allowing full or totally no illumination to exit the bulb via the disc;
- inserting the bulb into a power delivery fixture and generating an illumination;
- and
- moving the arm from the open to the closed position on Shabbat by a person observing orthodox Jewish law.
A Shabbat bulb which allows control of illumination without electrical intervention by a person observing strictures of Shabbat orthodox Jewish law, the bulb comprising:
- a housing covering an electrically operated light source, the housing having a power connecting end and an oppositely arranged illumination transmitting end, both ends being aligned along a common axis;
- a blackout mechanism separable from the illumination transmitting end and having no operating connection with electrical circuitry, the mechanism comprising:
- an outer ring having slots found on opposing sides of the outer ring;
- a disc being mounted coplanar to and supported within the outer ring;
- the disc including at least one disc aperture through which light from the light source is transmitted;
- and
- an arm projecting radially outward from the disc, the arm being rectangular in shape and having openings between first and second ends of the arm, and the arm slideably fitting through the slots found on the opposing sides of the outer ring, manual movement of the arm from an open position to a closed position respectively allowing full or totally no illumination to exit the bulb via the disc.
