Illumination device

An illumination device being electrically connected to an alternate current (AC) power source, said AC power source outputting an input voltage that has been rectified by a rectifier module, said illumination device comprising:

• a voltage transformer module, being electrically connected to said rectifier module;
• a switching unit, being electrically connected to said rectifier module and said voltage transformer module;
• a control module, being electrically connected to said switching unit and said voltage transformer module;
• a sensor module, being electrically connected to said control module, to sense an invading object within an induction area;
• a first illumination module, being electrically connected to said switching unit;
• and
• a second illumination module, being electrically connected to said sensor module;
• wherein said sensor module supplies electricity to said second illumination module to emit light, said sensor module outputs a sensing signal to said control module when said sensor module senses said invading object, and said control module controls said switching unit to be turned on so that said first illumination module emits light.
