Patent ID: 7717584

Claim:
A vibrating and twinkling LED backlighting device, comprises: a main body ( 1 ), said main body ( 1 ) comprises an opaque, hollow and polymorphous frame ( 11 ), and a cover plate ( 12 ) which is pervious to light disposed on the top of the frame ( 11 ) and corresponds to said frame ( 11 ); a circuit element ( 3 ), disposed inside the main body ( 1 ), said circuit element ( 3 ) comprises a circuit board ( 31 ), and a circuit-control element ( 32 ) which electrically connects with the circuit board ( 31 ); at least one light emitting device ( 4 ), electrically connected with the circuit of the circuit board ( 31 ) and the light emitting angle is parallel with the circuit board ( 31 ); said light emitting device ( 4 ) comprising: at least one Light-Emitting Diode (LED) ( 41 ) mounted on a side of the surface of said circuit board ( 31 ) and connected electrically therewith; a power supply ( 5 ), electrically connected with the circuit element ( 3 ) for supplying power; a ball-rolling switch ( 6 ), electrically connected with the circuit element ( 3 ) to control the operation of the circuit element ( 3 ); and a transparent encapsulation body ( 2 ) filled inside the main body ( 1 ) to cover said circuit element ( 3 ), power supply ( 5 ) and the ball-rolling switch ( 6 ); whereby when said ball-rolling switch ( 6 ) receives a vibration, it generates a trigger signal and the circuit-control element ( 32 ) receives said trigger signal, and it generates a driver signal to activate the light emitting device ( 4 ) to make the LED ( 41 ) twinkles in turn for a twinkle time, wherein the ball-rolling switch ( 6 ) having a conductive plate ( 67 ) which electrically connects with the circuit board ( 31 ), a housing ( 68 ) covering said conductive plate ( 67 ), and at least one metal bead ( 62 ) is mounted movably inside the housing ( 68 ) to provide current by contacting the circuit of said conductive plate ( 67 ), and a plurality of anode and cathode conductive points ( 671 , 672 ) are disposed in parallel formation on a surface of the conductive plate ( 67 ).
