Abstract

The present invention relates to a synchronously lighting apparatus of a vehicle meter. The digital signal transformed from the measured value triggers the light-emitting device of the light-outputting group so as to change the lighting status and triggers the display machine synchronously. Accordingly, an obvious warning is obtained.

Claims

1. A synchronously lighting apparatus of a vehicle meter, wherein an exterior main body of the vehicle meter consists of a meter shell and the synchronously lighting apparatus is a control loop that mounts inside the meter shell, the control loop comprising:

a signal transforming circuit formed on the control loop for electrically connecting with a target position of a vehicle and transforming a measured value of the target position into a digital signal;

a processing unit electrically connected with the signal transforming circuit for receiving the digital signal and performing operation and prosecution, the processing unit having a synchronization program for triggering at least a light-emitting device of a light-outputting group to change the lighting status in accordance with the digital signal;

the light-outputting group electrically connected to the processing unit and comprising the light-emitting device corresponding to a display machine; and

the display machine electrically connected to the processing unit, wherein

the signal transforming circuit electrically connects to the target position and the processing unit reads the measured value of the target position through the synchronization program such that when the processing unit performs the operation and the prosecution, the light-emitting device is triggered and the display machine is also triggered synchronously to display the measured value.

2. The synchronously lighting apparatus of the vehicle meter of claim 1, wherein the display machine is a LCD panel.

3. The synchronously lighting apparatus of the vehicle meter of claim 2, wherein the LCD panel is a digital simulated pointer type display panel.

4. The synchronously lighting apparatus of the vehicle meter of claim 1, wherein the display machine is a pointer display panel.

5. The synchronously lighting apparatus of the vehicle meter of claim 1, wherein the light-emitting device of the light-outputting group is a RGB light-emitting device to make the lighting status also become a color-changeable status.

6. The synchronously lighting apparatus of the vehicle meter of claim 1, wherein the target position is a wheel axle.
