<p>PURPOSE: A lamp device with a composite sensor and a connection type lamp system thereof are provided to supply an effective connection lamp corresponding to movement of a human by using the composite sensor composed of a short distance motion sensor and a long distance motion sensor. CONSTITUTION: A short distance motion sensor(120) senses a short distance object. A long distance motion sensor(130) senses a long distance object. A signal amplification unit(140) amplifies a sensing signal. A lamp(170) controls brightness. A timer(180) counts a dark adaptation time. A control unit(150) sets up a dark adaptation threshold. [Reference numerals] (110) Illuminance sensor; (120) Short distance motion sensor; (130) Long distance motion sensor; (140) Signal amplification unit; (150) Control unit; (160) Power unit; (170) Lamp; (180) Timer</p> |
