AUTOMATIC ILLUMINATION LAMP WITH LIGHT SOURCE AND OCCUPANCY SENSOR

摘要

An automatic lighting lamp having an integrated detection sensor and a light source is provided to improve energy efficiency through the operation according to surrounding environment by having a luminance sensor within the lamp. A body(1) has an opened groove having an opened bottom. A detachable spiral type electrode unit is formed on an upper end of the body(1). A cover plate(3) is formed on a lower part of the body(1) and covers the opened groove. A human body detection sensor(32) detects a plurality of LEDs and existence of people. A microcomputer controls to turn the LEDs on for a predetermined time according to a detection signal inputted from the human body detection sensor(32). A power supply unit converts and provides power inputted through the spiral type electrode unit into each element. A luminance sensor(35) detects luminance on a lower plane of the cover plate(3). The microcomputer controls to turn on/off the LEDs for a predetermined time when the detection signal is inputted from the human body detection sensor(32) and the detection signal inputted from the luminance sensor is below a predetermined value.
