Low energy decorative light bulb displays
First Claim
1. A decorative light bulb assembly comprising:
- a transparent bulb with surrounding interior reflective surfaces and a narrow base opening at one end;
a base structure adapted to be permanently affixed to said bulb at said base opening and containing opposing base terminals for supplying electrical power from a lamp socket;
a lamp string consisting of a plurality of unbased miniature lamps with elongated flexible wire leads connected end-to-end in series, said lamp string having a length substantially longer than the distance between said base terminals and the opposite end of said bulb and having its two ends electrically coupled to the opposing base terminals with one end affixed to the base; and
,twisting means for supporting a portion of said lamp string near said opposite end of said bulb at a point remote from the base for imparting a rotary spring-like tension that opens folds in said lamp string to distribute said lamps within said bulb at locations substantially displaced from the central axis and inner reflecting bulb surfaces, thereby producing myriad reflective images of said lamps within said bulb.

Abstract
The flexible wire leads of several unbased miniature lamps are welded or soldered end to end in series to form a lamp string that has one end electrically connected to a rigid center wire extending upwardly from the center foot terminal of a lamp base so that, with the base fitted on a spherical or other rounded transparent bulb, the lamp string connection to the rigid wire will be near the central longitudinal axis at the opposite end of the bulb. With the other end of the lamp string held stationary, the base is twisted within the bulb to expand the lamp string, which is folded in a flat S-shape to fit through the narrow tubular base opening in the bulb, until the lamps are each positioned within the bulb at locations displaced from the central axis and inner concave reflecting surfaces. This insures myriad reflected lamp images that give the visual impression of many more lamps with greater apparent illumination though requiring only a few watts of energy.
