Abstract
A sequential lighting device may include a power supply device configured for supplying the input power of a predetermined waveform, a sequential control circuit, which is an analog circuit, sequentially operated depending upon the input power to generate a sequential operation signal, and a switching circuit for turning on or off a plurality of light sources of a lamp module depending upon the sequential operation signal.
Claims20
A sequential lighting device, comprising:
- a power supply device configured for supplying an input power having a predetermined waveform;
- a sequential control circuit, which is an analog circuit and connected to the power supply device wherein the sequential control circuit is sequentially operated depending upon the input power to generate a sequential operation signal;
- and
- a switching circuit connected to the sequential control circuit and a plurality of light sources of a lamp module, wherein the switching circuit is configured for turning on or off the plurality of light sources of the lamp module according to the sequential operation signal received from the sequential control circuit.
