LED flashlight and printed circuit board therefore

An LED flashlight comprising:

• a housing for receiving a power source;
• a circuit board having a first surface and a second surface opposite said first surface, said
• a first conductor on said circuit board having a first section and at least a second section at least partially surrounding said first section;
• a second conductor on said circuit board having a first section between said first and second sections of said first conductor, said second conductor being electrically isolated from said first conductor;
• and
• a plurality of LEDs for providing light, each of said plurality of LEDs having a pair of terminals, each terminal of said pair of terminals being electrically connected to a separate one of said first and second conductors, said LEDs being electrically connectable to said power source to illuminate said LEDs.

A flashlight comprising:

• a housing having a first end and a second end, said first end being closed and configured to receive at least one battery, said second end having a cap;
• a circuit board having a first surface and a second surface opposite said first surface, said circuit board being positioned adjacent said second end of the housing, said first surface facing in a direction away from said cap;
• a first conductor on said first surface of the circuit board having a first section and at least a second section at least partially surrounding said first section;
• a second conductor on said first surface of the circuit board having a first section between said first and second sections of said first conductor and a second section at least partially surrounding said second section of said first conductor, said second conductor being electrically isolated from said first conductor;
• a plurality of LEDs for producing light, each of said LEDs having a pair of terminals, said LEDs being positioned on said second surface of the circuit board with each of the terminals of each of said plurality of LEDs being electrically connected to a separate one of said first and second conductors, said LEDs being positioned adjacent said cap;
• and
• a switch to electrically connect and disconnect at least one of said first and second conductors from the battery, when said batter is received, to turn the flashlight on and off.

A PCB for use in a flashlight having a plurality of LEDs as a light source, comprising:

• a circuit board having an insulating material and a first surface and a second surface opposite said first surface;
• a first conductor on said first surface of said circuit board, said first conductor having a central section and a semicircular second section at least partially surrounding and spaced from said central section and electrically connected thereto, said second section further comprising a gap;
• a second conductor on said first surface at least partially surrounding said second section of said first conductor and electrically isolated therefrom, said second conductor having a member extending into said gap towards said first section of said first conductor;
• a third conductor on said first surface of said circuit board at least partially surrouding said first and second conductors, said third conductor being electrically isolated from said first and second conductors.

A PCB for use in a flashlight having a plurality of LEDs as a light source, said PCB comprising:

• a circuit board comprising an insulating material and having a first surface and a second surface opposite said first surface;
• a first conductor on said first surface of said circuit board;
• a second conductor on said first surface of said circuit board at least partially surrounding said first conductor, said second conductor being electrically isolated from said first conductor;
• and
• a third conductor on said first surface of said circuit board at least partially surrounding said first and second conductors, said third conductor being electrically isolated from said first and second conductors;
• wherein said second and third conductors are configured to receive a resistor, said resistor coupled on a first end to the second conductor and on a second end to the third conductor.
