Abstract
Disclosed is a reliable, high strength, waterproof light string that has lamp housings secured along the length of a light string which maintains the integrity of the insulated power wire, which is not cut, to make connections to each of the light assemblies. Conductive connections are made between a circuit board and conductive screws that extend through the circuit board and penetrate an insulation layer of the power wire and extend into a stranded conductive lead. Assembly of the light string eliminates a number of complex steps and provides a better, and stronger light string that is not prone to separation.
Claims12
A light string that resists being pulled apart comprising:
- an insulated power wire having stranded conductive leads and insulation covering said conductive lead;
- a lamp holder surrounding said insulated power wire, said lamp holder having a cavity that exposes said insulated wire, said lamp holder fixed to said insulated power wire;
- a circuit board having light emitting diodes, said circuit board adapted to fit on said circuit board holder in a fixed position relative to said lamp holder so that openings in said circuit board align with conductive leads of said insulated power wire;
- a circuit board holder located in said cavity of said housing;
- printed circuit board leads on said printed circuit board proximate to or disposed in or around said openings in said circuit board;
- conductive screws that extend through said openings in said circuit board and are secured in said insulation covering and contact said stranded conductive leads without causing damage to said stranded conductive leads which creates a conductive connection between said printed circuit board leads and said conductive leads of said insulated power wire without cutting said insulated wire.
A method of making a light string that is strong and resists being pulled apart comprising;
- forming a lamp holder around an insulated wire so that said insulated wire passes through a cavity in said lamp holder;
- providing a circuit board having light emitting diodes, a power driving chip that converts power from power supplied to said light string to a voltage that can be used by said light emitting diodes to generate light;
- forming a circuit board holder in said cavity of said lamp holder to hold said circuit board in a predetermined position in said lamp holder;
- placing said diffuser in said lamp holder over said lens so that light is directed from said light emitting diodes to an inside surface of said diffuser;
- placing conductive screws in holes in said circuit board so that said screws are aligned with conductive leads of said insulated wire;
- screwing said screws through said holes in said circuit board and through insulation on said insulated wire and into said conductive leads at said insulated wire so that power is supplied to power leads on said circuit board without cutting said insulated wire and not weakening said insulated wire.
