ALTERNATING-CURRENT HIGH-VOLTAGE MULTI-SEGMENT PARTITIONED LIGHT SOURCE DRIVING DEVICE AND METHOD THEREOF

摘要

The present invention discloses an alternating high-voltage multi-segment partitioned light source driving device and method thereof. The device includes a power source, a signal control module, n segment constant-current driving modules, n MOS transistors and n segments of LED lights, where n is a natural number greater than or equal to 2. The signal control module is provided with an input end and n output ends. The power source separately connects electrically to the input end of the signal control module and the n segments of LED lights. Each of the constant-current driving module segments is connected in series with one corresponding MOS transistor in a one-to-one manner. The first to the m-th segments of LED lights are serially connected and then electrically connected to the m-th MOS transistor, where m is a natural number less than or equal to n. invention
