Control circuit, in particular for dimming an EC mirror glass of a rearview mirror of a motor vehicle |
摘要 |
A control circuit having particular application in dimming an EC (Electrochromic) mirror glass of a rearview mirror of a motor vehicle. Light flux from headlight glare of vehicles traveling behind is received by one conductor and filtered whereas light flux from the ambient light is received by a second conductor and filtered in a way that complements the first filtering. This allows a single sensor to be used to sense both the ambient light and the glare light which enables simpler control of the dimming function.
