Lamp group switching control device

A lamp group switching control device for switching and controlling a first lamp group and a second lamp group is provided. When receiving a first power source for driving the first lamp group, the lamp group switching control device controls that only the first lamp group provides a first light signal regardless of whether a second power source for driving the second lamp group is received. When the first power source is not received and the second power source is received, the lamp group switching control device controls that only the second lamp group provides the second light signal. 本发明提供一种灯组切换控制装置，用以切换并控制第一灯组与第二灯组。当接收到用以驱动第一灯组的第一电源时，灯组切换控制装置控制仅有第一灯组提供第一光信号而不论是否接收到用以驱动第二灯组的第二电源。当没有接收到第一电源，并且接收到第二电源时，灯组切换控制装置控制仅有第二灯组提供第二光信号。
