Abstract
A book light includes: a shade having a lamp and an electrical control circuit fixed within the shade, a base for pivotally mounting the shade and the lamp on the base, a clamping device protruding forwardly from the base to be clamped on a book, and a push-button switch resiliently held in the shade normally protruding outwardly beyond the shade, whereby upon closing of the shade on the base, the push-button switch will be retracted into the shade to turn off the lamp as depressed by the base when pivotally folding the shade on the base; and upon opening of the shade from the base, the push-button switch will be automatically protruded outwardly to close the electrical control circuit to power and turn on the lamp for lighting use.
Claims7
A book light comprising:
- a base having a clamping means secured to said base to be clamped on a book;
- a shade means pivotally secured on said base and having a lamp mounted in said shade means;
- and
- an electrical control circuit mounted in said shade means for powering the lamp, having a push-button switch resiliently held in said shade means and protruding outwardly beyond said shade means for closing the electrical control circuit;
- said shade means foldably closed on said base to retract said push-button switch inwardly in said shade means to disconnect the electrical control circuit to turn off said lamp;
- whereby upon an outward pivotal movement of said shade means to unfold said shade means from said base, said push-button switch is protruded outwardly beyond said shade means to close said electrical control circuit to automatically turn on said lamp for reading use;
- said base including:
- a platform secured with said clamping means and having an upper flat surface formed on the platform, and a pair of bushings bifurcated from the platform as generally U shaped, each said bushing formed with a pivot hole therein;
- and said shade means including:
- a shaft portion having a pair of pivots disposed on two opposite ends of the shaft portion each said pivot rotatably engageable with each said pivot hole formed in each said bushing of the base for pivotally mounting the shade means on the base, a shade portion laterally protruded from the shaft portion having a parabolic reflector formed on a back portion of the shade portion and a flat cover formed on a surface portion of the shade portion opposite to the parabolic reflector, and a lens fixed in the flat cover to define a lamp chamber in between the lens and the reflector for securing the lamp within the lamp chamber in said shade means.
