Reading light with shutoff timer
First Claim
1. An illumination device comprising the following:
- a lamp;
a lamp cover assembly comprising a lamp cover, a socket into which said lamp is inserted, and a rotatable coupling;
an arm rotatably connected to said lamp cover assembly by a first hinge located at one end of said arm;
a base rotatably connected to said arm by a second hinge located at an end of said arm most remote from the end to which said first hinge is connected;
a power source;
electrical circuitry sufficient to send power from the power source to the lamp, such that the lamp illuminates with a predetermined intensity;
a countdown timer, coupled to the electrical circuitry, that maintains the flow of power to the lamp via the electrical circuitry to permit the lamp to maintain illumination at the predetermined intensity until expiration of a user-defined time period and then automatically disconnects the flow of power to the lamp upon expiration of the user-defined time period;
a control device providing a user with the capability of setting the user-defined time period; and
a clip rotatably connected to said base and operable to attach the base to an object of illumination.

Abstract
The invention is a small, portable illumination device which is used to illuminate reading material or other material. The device contains a clip which a user can employ to attach the device to a book or other reading material. The clip holds the illuminating device in place relative to the material. The device uses either battery or alternating current as power and can be switched from one to the other by insertion or removal of a male plug of a 120V AC/DC adapter into or from a jack in the device. The device can be turned on or shut off when a user switches the ON-OFF switch. In addition, there is a countdown timer which the user can set to a desired number of minutes. Once the countdown timer starts, the device will illuminate the material for the number of minutes to which the user set the countdown timer. When the countdown timer reaches zero, the device shuts off automatically. A buzzer sounds when the countdown timer reaches two minutes. There is also a display which shows the number of minutes and seconds before the countdown timer reaches zero.

an upper section having a plurality of serrations on an underside thereof and further having a hinge end and a pincer end remote from the hinge end;
a pedestal attached to said base, wherein said upper section is rotatably connected to said base through said pedestal at the hinge end of said upper section; and
a rubber pad attached to the base at the point at which the pincer end contacts the base, said rubber pad preventing the object of illumination from slipping out from under the serrations of the upper section.
