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.

1 - 25 . (canceled) 
     
     
         26 . A bulb having a circuit capable of maximizing the perceived brightness of a series lighting circuit comprising a plurality of series connected incandescent bulbs with wound tungsten filaments, at least one of said bulbs comprising:
 a. a base;   b. at least a pair of electrical contacts in said base;   c. a pair of leads connected to said contacts;   d. an elongated airtight envelope having a generally transparent domed canopy top, secured to said base, said envelope having a converging portion and a top distal apex terminating in a generally bulbous peak thereby creating a transparent light pipe to an end and a bottom end proximal to said base; wound illumination filament connected to said leads inside said envelope, said leads to the filament being of sufficient length to locate said filament inside said envelope being proximate said canopy top and adjacent said peak thereof so that most light extending radially from the filament will pass though the peak and, so that heat generated is more distant from the base and more light is transmitted to said end through said light pipe, therefore providing a perceived high brightness point source without increasing power consumption.   
     
     
         27 . The bulb of  claim 26  wherein said filament is made of a purer tungsten material than industry standard filaments. 
     
     
         28 . The bulb of  claim 26  wherein said leads are extended to places said filament adjacent to the canopy top of the envelope. 
     
     
         29 . The bulb of  claim 26  further including a nonconductive junction with the leads passing therethough, said junction providing an insulated lead spacer therebetween, and wherein said filament is closer to the distal end of the envelope than the nonconductive junction. 
     
     
         30 . A bulb capable of maximizing the perceived brightness of a series lighting circuit comprising a plurality of series connected incandescent bulbs with wound tungsten filaments, a bypass resistor in parallel with one of the incandescent bulbs, at least one of said bulbs comprising a structure for increasing the perceived brightness of incandescent bulbs and reducing heat transmission from the filament to the base, and further comprising:
 a. each of said bulbs including a tightly wound filament, and wherein each of said bulbs includes a base, a least a pair of electrical contacts in said base, and   b. a pair of leads connected to said contacts, an elongated airtight envelope having a generally tubular section, a tapered section and a transparent domed canopy top terminating in an apex having a generally bulbous peak, thereby creating a transparent light pipe end of generally solid material, secured to said base, said envelope having a top distal end and a bottom end proximal to said base, wound illumination filament connected to said leads inside said envelope, so that most light extending radially from the filament will pass though the peak; said leads to the filament being of sufficient length to locate said filament inside said envelope being proximate said canopy top thereof so that heat generated is more distant from the base and more light is transmitted through said light pipe.   
     
     
         31 . A method of maximizing the perceived brightness of each series connected incandescent bulb without increasing current flow, having a wound tungsten filament, a glass canopy, in a string of bulbs for decorative lighting to permit lower power bulbs to be used but with substantially similar perceived brightness comprising the steps, in any order, of:
 a. forming a base;   b. placing at least a pair of electrical contacts in said base; a pair of leads connected to said contacts;   c. forming an airtight envelope secured to said base, with a generally transparent domed canopy top at its distal end said canopy top converging to an apex and terminating in a generally bulbous peak thereby creating a transparent light pipe, and a bottom end proximal to said base; forming said canopy to converge generally toward an apex, thereby effectively creating a light pipe to a terminating at said apex, so that most light extending radially from the filament will pass though the peak;   d. placing an illumination filament within the envelope, said filament being configured to reduce the current flow therethrough as less energy is required to achieve the same perception of brightness;   e. locating said filament in an upper half of the canopy proximate said apex;   f. connecting the filament to said leads inside said envelope;   g. providing extended leads from the base to a point adjacent the distal end of the envelope.   
     
     
         32 . The method of  claim 31  further including connecting a bypass resistor in parallel with one of the bulbs, and locating the resistor within the envelope; to be capable of operating on a one hundred percent duty cycle as desired. 
     
     
         33 . The method of  claim 31  further including connecting a bypass resistor in parallel with one of the bulbs and locating the resistor within the base; to be capable of operating on a one hundred percent duty cycle as desired. 
     
     
         34 . The method of  claim 31  further including locating said filament closer to said apex than said bottom end. 
     
     
         35 . The method of  claim 31  further including forming said canopy to be tapered toward its apex, creating a tapered portion and locating said filament adjacent the tapered portion. 
     
     
         36 . The method of  claim 31  further including forming the apex as a solid globe of transparent material to create a light transmitting point.
