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...

Description

technical field [0001] The present invention relates to the lighting field, and more specifically, the present invention relates to an indoor lighting device. Background technique [0002] A light-emitting diode light source is a light source including one or more light-emitting diodes (LEDs). Due to the high luminous efficiency and long life of the light-emitting diodes, the light-emitting diode light source has attracted much attention as a next-generation lighting device. By selecting various parameters of the LEDs included in the LED light source and the number of LEDs, it is possible to realize LED light sources with brightness meeting various needs and different powers. For example, light-emitting diode light sources can be used as various lighting devices such as ceiling lamps, table lamps, long tube lamps for indoor lighting, and street lamps for outdoor lighting. [0003] Because light-emitting diodes have the characteristics of DC drive, when the light-emitting di...
