<p><P>PROBLEM TO BE SOLVED: To provide a driving device which drives and emits a cluster lamp dot beam consisting of a plurality of light emitting diodes. <P>SOLUTION: This invention relates to the driving device of the cluster lamp dot beam which drives a plurality of emission elements in one cluster lamp dot beam by viewing and listening signal data. The driving device of the cluster lamp dot beam receives the viewing and listening signal data transmitted from a control system by a controller, divides the viewing and listening signal data into three pieces of sub-viewing and listening signal data and simultaneously and repeatedly outputs the three pieces of sub-viewing and listening signal data to a digital/analog converter by every fixed time. The digital/analog converter converts the three pieces of sub-viewing and listening signal data into three pieces of analog voltage and outputs the analog voltage to a voltage/current converter. The voltage/current converter converts, outputs the three pieces of analog voltage into three pieces of analog current, drives the emission elements to emit light. The driving device drives the cluster lamp dot beam consisting of the plurality of light emitting diodes, generates luminance according to variation of an amount of current and generates variation of many kinds of colors and patterns according to the control system. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
