Abstract

The present invention provides a table lamp adapter system for providing interchangeability between incandescent and fluorescent light bulbs. There is provided a table lamp system which includes a detachable lamp holder tubular housing 1 in combination with selector switch mechanism 2 and a three-step power switch 5 wherein the lighting source, whether it be fluorescent lamps or incandescent lamps, of the table lamp, is changeable to meet the user'"'"'s wishes. Additionally, a support arm 7 is detachable from the overall system for separate storage to minimize space consumption.

Claims

1. A table lamp adapter system for providing interchangeability between incandescent and fluorescent light bulbs, comprising:

(a) a lamp holder tubular housing having a front section coupled to said light bulb and a rear section having a stub member protruding therefrom;

(b) selector switch means for switching reversibly from incandescent to fluorescent light bulb power actuation, said selector switch means including a contact plug member received within said lamp holder tubular housing;

(c) a sleeve member having a guide slot formed therein, said stub member being linearly displaceable within said guide slot;

(d) a spiral coupling having internal threads and rotatable responsive to said linear displacement of said stub within said guide slot, said spiral coupling being mounted on said sleeve member on a frontal portion thereof in a manner such that through alignment of said internal threads with said guide slot, said stub member is displaced within said guide slot;

(e) a support arm member fixedly coupled to a rear portion of said sleeve member, said selector switch means further including a conduction member having four terminals arranged in two sets, said conduction member being mounted in said sleeve member, said conduction member further including a front end surface member having four recess holes and a rear end surface member which includes four mandrels for mounting thereon of four springs respectively wherein two pairs of terminals are respectively mounted on said springs, said springs in alignment with said mandrels and recess holes of said front end surface member, said terminals being resiliently mounted whereby a pair of contact noses of said contact type plug may be selectively in contact with said pairs of said terminals of said conduction member.

2. The table lamp adapter system as recited in claim 1 including a washer mounted between said sleeve member and said lamp holder tubular housing to smooth connection between said stub member and said sleeve member.
