Abstract

A resistor bypass circuit for a series lighting circuit includes a plurality of serially connected light sources and a bypass resistor being connected in parallel with at least one of the respective light sources, each respective light source being low wattage and being capable operating on a one hundred percent duty cycle as desired.

Claims

1. A method of constructing a miniature light bulb for use in an ornamental light set having a plurality of relatively low wattage bulbs wired together into a string having a base and a distal top canopy, the bulb being configured to enhance its perceived brightness, while using less energy and obtaining longer life than industry standard miniature bulbs, method of constructing the bulb, comprising the steps of:

forming a base;

forming a least a pair of electrical contacts in said base,

forming a pair of leads connected to said contacts,

forming an airtight envelope secured to said base into an elongated envelope having a generally transparent tapered canopy where the canopy walls converge to a pointed apex thereby having a focusing lens effect at its distal end distant from the base,

forming an illumination element connected to said leads inside said envelope;

extending the leads from the base to a defined point higher into the canopy top at the distal end of the envelope,

locating the illumination element adjacent the distal end of the envelope near the canopy to increase its perceived brightness by the effect of the tapered canopy, so that a viewer seeing the illumination from the canopy end, will perceive a more concentrated light source.

2. The method of claim 1 further including the step of connecting a bypass resistor in parallel with at least one of the plurality of bulbs and locating the resistor within the base.

3. The method of claim 1 further including the step of connecting a bypass resistor in parallel with at least one of the plurality of bulbs and locating the resistor within the base to be capable of operating on a one hundred percent duty cycle as desired.

4. The method of claim 1 further including the step of locating said illumination element closer to said distal end than said base.

5. The method of claim 1 further including the step of forming said canopy to be tapered toward its distal end, creating a tapered portion and locating said illumination element adjacent the tapered portion.

6. The method of claim 1 further including the step of forming the distal end as a solid globe of transparent material to create a light transmitting point.

7. The method of claim 1 including forming the canopy top with a bulbous end.

8. A method of constructing a miniature light bulb for use in an ornamental light set having a plurality of relatively low wattage bulbs wired together into a string having a base and a distal top canopy, the bulb being configured to enhance its perception of brightness to a viewer, while using less energy method constructing the bulb, comprising the steps of:

forming a base;

forming a least a pair of electrical contacts in said base,

forming a pair of leads connected to said contacts,

forming an airtight transparent envelope secured to said base into an elongated tapered canopy where the canopy walls converge to a pointed apex having a bulbous transparent tip,

locating the illumination element immediately adjacent the tapered canopy thereby creating a focusing lens effect at the tip where the tip produces a perceived point of high brightness when viewed head on, thereby allowing the use of lower power consumption to achieve a similar level of perceived brightness.
