Embodiment Construction
[0028] An indoor lighting device according to an exemplary embodiment will be described in detail below with reference to the accompanying drawings.
[0029] figure 2 is a schematic block diagram illustrating a light source driving circuit according to an exemplary embodiment. Such as figure 2 As shown in , the light source drive circuit according to the exemplary embodiment includes a rectifier bridge circuit 1 , a voltage regulation circuit 2 and a light emitting diode drive source circuit 3 .
[0030]The input end of the rectifier bridge circuit 1 is connected to an external power supply. The external power supply is, for example, a commercial power supply or other AC power supply with a rated frequency of 50 Hz or 60 Hz and a rated voltage of 110 V or 220 V. The rectifier bridge circuit 1 converts an AC voltage supplied from an external power source into a DC voltage. The rectifier bridge circuit 1 provides the rectified first output to the voltage regulation circuit...
