Description:
FIELD OF THE INVENTION  
      The present invention relates to shoes with light emitting diodes, and particular to a multi-color shoe lamp device, which are driven by two different voltage levels so as to present different flash effect.  
     BACKGROUND OF THE INVENTION  
      In the prior art U.S. Pat. No. 6,525,487, assigned to the inventor of the present invention, in that the power supply of a shoe is formed by a first battery of 1.5V and a second battery of 3.0V. The first and second batteries are serially connected so as to have a voltage of 4.5V which can afford voltages of 3.0 V and 4.5V to light emitting diodes.  
      The wavelength of visual light is from 4000 to 7000 angstroms (1 A°=10 −8  cm=10 −4  micrometer). In general, the wavelength of purple light is between 4,000˜4,500 angstrom, the wavelength of blue light is between 4,500˜5,200 angstrom, the wavelength of green light is between 5,200˜5,600 angstroms, the wavelength of yellow light is between 5,600˜6,000, the wavelength of original light is between 6,000˜6,250 angstrom, and the wavelength of red light is between 6,250˜7,000 angstrom. Voltage of 3.0V serves to light up the light emitting diodes of red color, orange color, green color, etc., and voltage above 4.5V serves for lighting up the light emitting diodes of blue color, purple color, pink color, white color, etc. because the lighting emitting diode emitting these colors need high voltages to drive them so as to emit lights with sufficient strengths.  
      Through experiences of many times, it is discovered that if a voltage above 4.5V, for example, 6.0V is used to drive the light emitting diodes of blue color, purple color, pink color, white color, etc., then these diodes can emit lights with stronger strengths than the result got by using a voltage of 4.5V, and a voltage of 4.5V is supplied to the light emitting diodes of red color, orange color, green color, etc., then the emit lights have strengths and effects preferred than those used in the prior art.  
      The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

      With reference to  FIG. 4 , in the multi-color shoe lamp device  10  of the first embodiment, the pins L 1  to L 3  are retained to the output pins of the single color light emitting diodes  61  to  63 . The pin VDD is a positive electrode with a DC of 3.0 Volt. The pin VSS is a negative electrode. The pin TRIG serves for triggering the vibration switch  7 . The power source is formed by a first battery  2  of 3.0V and a second battery  3  of 1.5V so as to provide voltage levels of 3.0V and 4.5V to the substrate  4  and the single color light emitting diodes  61  to  63 . The first voltage  2  is connected to the anodes of the red color light emitting diode  61  and the green color light emitting diode  62 . The second battery  3  is connected to the anode of the blue color light emitting diode  63 . Since the first battery  2  and the second battery  3  are serially connected to have a voltage of 4.5V Thereby, a voltage level of 3.0V is provided to the red color light emitting diode  61  and the green color light emitting diode  62  and a voltage level of 4.5V is provided to the blue color light emitting diode  63 .  
      Similarly, when a first battery of 3.0 V and a second battery of 3.0 V are serially connected. Then voltages of 3.0 V and 6.0V are provided. That is, the first voltage  2  is connected to the anodes of the red color light emitting diode  61  and the green color light emitting diode  62 . The second battery  3  is connected to the anode of the blue color light emitting diode  63 . Since the first battery  2  and the second battery  3  are serially connected to have a voltage of 6.0V. Thereby, a voltage level of 3.0V is provided to the red color light emitting diode  61  and the green color light emitting diode  62  and a voltage level of 6.0V is provided to the blue color light emitting diode  63 .  
      In the second embodiment, see  FIG. 5 , the pins BPIN, GPIN, and RPIN are connected to the single color light emitting diodes  63  and  66 . The pin V 3 V is a positive electrode of a DC of 3.0 volt. The pin VDD is a positive electrode of 4.5 volt (or 6.0 volt). The pin VSS is a negative electrode of the power source. The pin CY serves for the vibration switch  7 . Besides, the single color light emitting diodes  64 - 66  provide various colors by the visual effect (about 1/16 second to 1/24 second).  
      With reference to  FIG. 6 , in the third embodiment, the pins L 1  to L 3  are used for the output pins of single color light emitting diodes  61  to  63 , the pins BPIN, GPIN, and RPIN are connected to the single color light emitting diodes  63  and  66 . The pin V 3 V is positive electrode of a DC of 3.0 volt. The pin VDD is a positive electrode of 4.5 volt (or 6.0 volt). The pin VSS is a negative electrode of the power source. The pin TRIG serves for the single shot triggering or level triggering the vibration switch  7 . The pin CY serves for triggering the switch S 1 . The pins OSC 1  and OSC 0  are connected to a vibrating resistor  8 . By adjusting the vibrating resistor  8 , the pulse is changed.  
      The IC control circuit  40  used in the third embodiment is illustrated in  FIG. 3 .

The trigger unit  44  is connected to the vibrating switch  7 . When the vibration switch  7  vibrates, a first trigger signal is generated to the first delay unit  45  and the control unit  46 . The first delay unit  43  serves to cause the IC control circuit  40  to delay the driving signals to the single color light emitting diode  61 ,  62 ,  63  and the single color light emitting diodes  64  to  66 . In the flash time period, if no new triggering signal is generated, the control unit  46  is disabled.  
      When the substrate  4  vibrates, the trigger unit  44  generates a trigger signal to the control unit  46 . The control unit  46  sends driving signals to the single color light emitting diodes  61  to  63  and the single color light emitting diodes  64  to  66  after a delay time which is determined by the second delay unit  43 . At this time, these single color light emitting diodes  61  to  66  flash according to the flash time sequence determined by the second delay unit  45 .  
      With reference to  FIG. 8 , it is illustrated that the present invention is installed within a shoe body  9 . The light emitting diodes are installed at the periphery of the shoe. The single color light emitting diodes  61  to  63  can flash along various sequences or the single color light emitting diodes  64  to  66  can present various colors by mixing of the lights of different colors.  
      The power supply, vibration switch and IC circuit are assembled in a casing and the single color light emitting diodes are installed at a shoe which can be seen from outer side of the shoe.
