ABSTRACT:
A detecting apparatus for a lamp is disclosed. The detecting apparatus includes a central processing unit for receiving a spectrum signal and converting the spectrum signal into a digital signal, a converter for converting the digital signal to an analog signal, a controller for receiving the analog signal and generating an operating signal, and an amplifier for receiving the operating signal and outputting a voltage signal to activate the lamp, wherein the spectrum signal is analyzed and differentiated such that an operating condition for the lamp is obtained.
