Abstract

A shoe light device with multiple color variations has at least a color-mixing LED, a power source, a vibration switch and a control IC. The color-mixing LED has 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 a trigger signal to the control IC when shocked. The control IC generates a drive signal to drive the color-mixing LED to flash a single-color light at least once after receiving the trigger signal. The color-mixing LED flashes a different single-color light each time according to a light color table determining the color variation order and frequency after receiving the drive signal. When a user wearing a shoe with the shoe light device installed therein walks, variations of different single-color lights can be displayed along with his steps.

Claims

1. A shoe light device with multiple color variations, comprising:

at least a color-mixing LED composed of several light-emitting chips of different colors, said color-mixing LED being used to generate lights of several 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 drive said color-mixing LED to flash a single-color light at least once when receiving said trigger signal, said color-mixing LED flashing a different single-color light each time according to a light color table determining the color variation order and times after receiving said drive signal.

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

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

4. The shoe light device with multiple color variations as claimed in claim 1, wherein said color-mixing LED is disposed upon a visible portion of a shoe.

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

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

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

8. The shoe light device with multiple color variations as claimed in claim 1, wherein said power source is 6V.

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

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

11. The shoe light device with multiple color variations 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 count unit electrically connected to said trigger unit and used to count frequency of said trigger signal for generating a reset 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 said drive signal to said color-mixing LED drive unit, said control unit also inducing said color-mixing LED to flash different single-color lights circularly again according to said light color table after receiving said reset signal.

12. The shoe light device with multiple color variations as claimed in claim 11, wherein said control IC further comprises a function selection unit, which determines said light color table through a switch.

13. The shoe light device with multiple color variations as claimed in claim 11, wherein said control IC is further electrically connected to several secondary lights of LEDs.

14. The shoe light device with multiple color variations as claimed in claim 11, wherein said control IC further comprises a delay unit for controlling illumination time of said color-mixing LED.

15. The shoe light device with multiple color variations as claimed in claim 11, wherein said count unit generates said reset signal only when the frequency of said trigger signal equals the total times of color variation in said light color table.
