<p>PURPOSE: An apparatus for controlling an LED lamp to maximize environmentally-friendly energy and save power is provided to easily save power and manage energy by controlling the on and off of an LED lamp through an indoor unmanned sensor. CONSTITUTION: A first illumination detector(400) checks indoor illumination by sensing the presence of man through an unmanned sensor(200). The first illumination detector includes a second power mode converter(410) to be automatically or passively turned on and off. An SMPS(Switched-Mode Power Supply, 500) converts the power applied from the first illumination detector into rated voltages. A first control circuit(600) is driven with the power from the SMPS. An LED unit is controlled by the first control circuit.</p> |
