Apparatus for controlling CCFL and method for operating the same
First Claim
1. A method controlling a flashing of a cold cathode fluorescent lamp (CCFL) by fetching an audio signal on a motherboard, comprising steps of:
- supplying a power from the motherboard and boosting the power to a high voltage power for lighting the CCFL;
fetching a digital audio signal from the motherboard and converting the digital audio signal into a lighting pulse signal according to at least one of an audio frequency and an audio volume; and
controlling on and off of the high voltage power according to the lighting pulse signal, thus driving the CCFL in a flashing manner.

Abstract
A flashing apparatus controlled by an audio signal on a motherboard and a method for the same is proposed. The flashing apparatus has at least one cold cathode fluorescent lamp (CCFL), a motherboard and a controller. The CCFL is connected to a high voltage cable and receives a high voltage power to emit light of at least one color. The motherboard executes a sound effect software to send a lighting pulse signal to the controller. The controller is electrically connected to the high voltage power for the CCFL. The controller receives the lighting pulse signal and converts it into the high voltage power to make the CCFL flash.
