TITLE:DIGITAL TRAFFIC SIGNAL DEVICE BACKGROUND OF THE INVENTION
The present invention relates to a digital traffic signal device. More particularly, the present invention relates to a digital traffic signal device which has a digital display portion and a traffic signal display portion.
A conventional traffic light device has a green light, a yellow light, and a red light. However, the green light, the yellow light and the red light do not show the time period at all. SUMMARY OF THE INVENTION
An object of the present invention is to provide a digital traffic signal device which has a digital display portion to display a minute digital and two second digitals.
Another object of the present invention is to provide a digital traffic signal device which has a control electric circuit board to set a time period and to count the time period backward.
Another object of the present invention is to provide a digital traffic signal device which has a traffic signal display portion to display a green signal and a red signal. BRIEF DESCRIPTION OF THE DRAWINGS

The traffic signal display portion 11 comprises a large number of green light emitting diodes 111 and a large number of red/green siamese light emitting 05 diodes 112. The digital display portion 12 comprises a digital indicator device 12a. The digital indicator device 12a comprises a minute indicator 121 and two second indicators 122. Referring to FIG. 3, a digital traffic signal 10 device 1' comprises a rear cover 1021, a front cover 1011 coupling with the rear cover 1021, a solar energy collector panel 13' disposed on a top portion of the digital traffic signal device V, a traffic signal display portion 11' disposed on a front portion of the digital traffic signal device 11, and a light emitting diode indicator portion 121 disposed on the front portion of the digital traffic signal device V. The traffic signal display portion 111 comprises a large number of green light emitting diodes 111' and a large number of red/green siamese light emitting diodes 112'. The light emitting diode indicator portion 12' comprises a first light emitting diode unit 123' and a second light emitting diode unit 1241.
Referring to FIG. 4, the control electric circuit board 2 begins to operate.
3 Block 101: Start an operation of the control electric circuit board 2.
Block 102: Set a time period and count the time period backward.
