摘要： An illumination apparatus includes a rectifier, a linear regulator, a lighting unit and a temperature sensing control circuit. The rectifier is connected to an AC supply voltage. The regulator is electrically connected to the rectifier and is adaptive to a first voltage. The lighting apparatus and the regulator form a circuit coupled to the AC power supply. The lighting unit has first and second loads having respective first and second lighting components adaptive to the first voltage. The control circuit can effectively sense the temperature of the regulator and thereby determines whether the first and second load are connected in series or in parallel. If the supply voltage is the first voltage, the first and second load is connected in parallel. If the supply voltage is a second voltage greater than the first voltage, the temperature sensing control circuit switches the first and second load to be connected in series.
