1. A headlamp apparatus for wearing by a human, comprising in combination:

  • a widely adjustable headband including an elongated flexible circumferential band member and an elongated flexible longitudinal band member;

    said circumferential band member having two oppositely disposed terminal ends, one of said terminal ends affixed with an elongated portion of hook fastener, and the other of said terminal ends affixed with an elongated portion of loop fastener, said affixed hook and loop fasteners of said terminal ends placeable to be facing one another so as to be able to be releasibly connected together in an overlapping arrangement;

    said longitudinal band member having one end thereof affixed to said circumferential band member generally centrally between said terminal ends of said circumferential band member and in a portion of said circumferential band member intended to be placed adjacent a person'"'"'s forehead, a distal end of said longitudinal band member affixed with an elongated portion of hook fastener on one side thereof and further being affixed with an elongated portion of loop fastener on an oppositely disposed side from said hook fastener of said longitudinal band member, said hook fastener of said longitudinal band member placeable to be facing said loop fastener of a said terminal end of said circumferential band member simultaneously with said loop fastener of said longitudinal band member facing said hook fastener of the other said terminal end of said circumferential band member;

    said elongated portions of said hook and loop fasteners of said terminal ends of said circumferential band member being sufficiently elongated to provide for adjustability of placement against one another so as to allow said circumferal band member to be snugly affixed around a variety of head sizes simultaneously with said distal end of said longitudinal band member being sandwiched and affixed between said terminal ends of said circumferential band member with said loop fastener of said longitudinal band member affixed to said hook fastener of one said terminal end, and said hook fastener of said longitudinal band member affixed to said loop fastener of the other said terminal end of said circumferential band member, said elongated hook and loop fastener portions of said distal end of said longitudinal band member being sufficiently elongated so as to allow for adjustable fastening thereof to and between said terminal ends with said longitudinal band member extending across a person'"'"'s head simultaneously with said circumferential band member affixed around the person'"'"'s head;

    a lamp assembly affixed generally centrally to said circumferential band member by an adjustably positionable linkage member, said linkage member providing connective structural means between said headband and said lamp assembly to allow both selective vertical and horizontal positioning of said lamp assembly, said lamp assembly including a lamp housing having a lens affixed in a free end of said housing generally oppositely disposed from said linkage member, a reflector retained inside said housing, a lamp socket within said housing, an electric lamp releasably mounted in said lamp socket and positioned at least in part between said reflector and said lens, means providing selective adjustability of spacing between said lens and said lamp for focusing light emitted from said lamp;

    a remote battery housing containing at least one battery, electrical conductors extending between said battery housing and said lamp socket to circuit electrical power from said battery to said lamp, an electrical on/off switch in line with at least one of said electrical conductors to provide means for turning said lamp on and off, said battery housing having means for releasable attachment onto an article of clothing;

    voltage transforming and cord means connectable to and between a remote A/C power outlet and an electrical jack on said battery housing for recharging said battery with said battery contained within said battery housing, said voltage transforming and cord means further providing means for supplementing electrical power circuited from said battery to said lamp to extend a period of time which said lamp may be operated.
