<p>PURPOSE: A fluorescent lamp illumination adjusting apparatus and a detecting apparatus thereof are provided to maximize an energy saving effect by combining a human body passive infrared sensor and managing luminescent brightness with the most effective method. CONSTITUTION: An amplifier circuit(123) is respectively connected to a passive infrared sensor(120) and a CDS(Cadmium sulphide) sensor(121). The amplifier circuit amplifies a first sensing signal generated in the passive infrared sensor, and a second sensing signal generated in the CDS sensor. A detection circuit(124) detects potential of the second sensing signal and the first sensing signal. A processing unit(125) creates a conditioning signal based on the first sensing signal and the second sensing signal. An output unit(126) is connected to the processing unit and receives and outputs the conditioning signal.</p> |
