Patent ID: 7419275

Claim:
A magnetic attraction illuminated pen comprising a luminary ( 5 ) includes a conducting shell ( 55 ), a plurality of batteries ( 54 ) mounted inside the conducting shell ( 55 ), and a light emitting diode (LED) ( 50 ); a light guide tube ( 4 ) disposed to a proximal end ( 55 a ) of the conducting shell ( 55 ), a conducting member ( 6 ) with a conducting pole ( 60 ) disposed to a distal end ( 55 b ) of the conducting shell ( 55 ), a conical metal hood ( 2 ) is disposed to a proximal end of the light guide tube ( 4 ), a refill ( 3 ) can move to and fro inside the conical metal hood ( 2 ) and the light-guide tube ( 4 ), a cap member ( 1 ) fits over the conducting shell 55 for writing characterized in that: the LED ( 50 ) inside the conducting shell ( 55 ) emits light toward the light guide tube ( 4 ), a first lead ( 502 ) of the LED ( 50 ) connected to an anode of the battery ( 54 ), a second lead ( 501 ) connected to the conducting shell ( 55 ); a cathode of the battery ( 54 ) connected to the conducting pole ( 60 ), an insulated film ( 56 ) wraps around an outer wall of the battery ( 54 ), which is therefore out of contact with the conducting shell ( 55 ); an insulation ring ( 61 ) disposed around the conducting pole ( 60 ), which is thereby insulated from the conducting shell ( 55 ); a magnet ( 19 ) mounted inside a cap ( 14 ) of the cap member ( 1 ) attracts distal ends ( 601 ), ( 551 ) of the conducting pole ( 60 ) and the conducting shell ( 55 ) with magnetic attraction to conduct electric current to light up the LED ( 50 ).
