Abstract

A full-color shoe light device has at least a color-mixing LED, a power source, a vibration switch and a control IC. The color-mixing LED is several light-emitting chips of different colors, and is used to generate light of various colors. The power source provides electricity for the color-mixing LED. The vibration switch generates and sends a trigger signal to the control IC when vibrated. The control IC generates a drive signal to drive the color-mixing LED to emit multiple color variations in a flashing episode after receiving the trigger signal. When a wearer wearing a shoe with the full-color shoe light device installed therein walks, multiple color variations can be displayed along with his or her steps.

Claims

1. A full-color shoe light device comprising:

at least a color-mixing LED composed of several light-emitting chips of different colors integrated in a single lamp-shape package, said color-mixing LED being used to generate light of various colors;

a power source for providing electricity for said color-mixing LED;

a vibration switch for generating a trigger signal when vibrated; and

a control IC for generating a drive signal to control a lighting duration of each light-emitting chip in said color-mixing LED to emit light of multiple colors in a flashing episode after receiving said drive signal.

2. The full-color shoe light device as claimed in claim 1, wherein said color-mixing LED is composed of light-emitting chips of red, green and blue colors.

3. The full-color shoe light device as claimed in claim 1, wherein said color-mixing LED has 3 or 4 pins.

4. The full-color shoe light device as claimed in claim 1, wherein said color-mixing LED is installed on a visible portion of a shoe.

5. The full-color shoe light device as claimed in claim 1, wherein said power source is a 4.5V power source, and is composed of a 3V battery and a 1.5V battery.

6. The full-color shoe light device as claimed in claim 5, wherein said 3V battery is a lithium battery.

7. The full-color shoe light device as claimed in claim 6, wherein said lithium battery is a CR-2032 or CR-2450 lithium battery.

8. The full-color shoe light device as claimed in claim 1, wherein said power source is a 6V power source.

9. The full-color shoe light device as claimed in claim 8, wherein said 6V power source is composed of two 3V lithium batteries.

10. The full-color shoe light device as claimed in claim 9, wherein said lithium batteries are CR-2032 or CR-2450 lithium batteries.

11. The full-color shoe light device as claimed in claim 1, wherein said control IC comprises:

a trigger unit electrically connected to said vibration switch and used to generate said trigger signal;

a color-mixing LED drive unit for driving said color-mixing LED to emit light; and

a control unit used to receive said trigger signal, and to generate and send said drive signal to said color-mixing LED drive unit to make said color-mixing LED emit multiple colors according to a light color table.

12. The full-color shoe light device as claimed in claim 11, wherein said control IC further comprises a function mode unit to control color variation of said light color table by switches.

13. The full-color shoe light device as claimed in claim 11, wherein said control IC is further electrically connected to several monochrome LEDs.

14. The full-color shoe light device as claimed in claim 11, said control IC further comprising a first delay unit, wherein said first delay unit determines a delay time, whereafter said control IC generates and sends said drive signal to said color-mixing LED upon receiving said trigger signal.

15. The full-color shoe light device as claimed in claim 11, said control IC further comprising a second delay unit, wherein said second delay unit determines a length of said flashing episode.

16. A full-color shoe light device comprising:

at least a color-mixing LED composed of several light-emitting chips of different colors, said color-mixing LED being used to generate light of various colors;

a power source for providing electricity for said color-mixing LED;

a vibration switch for generating a trigger signal when vibrated; and

a control IC for generating a drive signal to said color-mixing LED to emit light of multiple colors in a flashing episode after receiving said drive signal,

wherein said control IC disables any trigger signal generated in said flashing episode.
