Patent ID: 8106608

Claim:
A lighting system comprising: a lamp; a power source; a switch; a time detecting circuit; a controlling circuit; and a driving circuit; wherein the lamp, the power source, the switch, the time detecting circuit, the controlling circuit and the driving circuit are electrically connected together; wherein the time detecting circuit produces different signals to the controlling circuit according to switching times of the switch, and the lamp lightens with different brightness according to the different signals in the switching times; wherein the power source comprises an AC/DC convertor, a DC/DC convertor and a power supply module, the DC/DC convertor being connected to the AC/DC convertor and having two output routes to provide power; wherein one of the two output routes is connected to the power supply module, and another one of the two output routes is connected to the driving circuit; and wherein the switch comprises a trigger and a flip-flop, the trigger being electrically connected to the power supply circuit, and the flip-flop being electrically connected to the time detecting circuit.
