<p>PURPOSE: A sensor lamp control circuit is provided to package a sensor driving circuit and a lamp driving circuit into one module form, thereby simplifying a circuit configuration. CONSTITUTION: A power supply unit(100) comprises a filter unit and a rectifying unit. The filter unit removes the noise of the AC power source. The rectifying unit rectifies the filtered voltage into the DC voltage. A sensor driving circuit(200) outputs a driving control signal. A lamp driving circuit(300,400) is connected to the sensor driving circuit by a signal. [Reference numerals] (110) Filter unit; (120) Rectifying unit; (20) Lamp; (200) Sensor driving circuit; (221) Illumination sensor; (231) Human body detecting sensor; (300,400) Lamp driving circuit</p> |
