Abstract:
1. A lighting device, comprising: a power management module configured to connect with alternating-current power, process the alternating-current power, and output direct-current power; a light source driving module electrically coupled to the power management module and configured to receive the direct-current power output by the power management module, process the received direct-current power, and output a light source driving signal; a first lighting unit electrically coupled to the light source driving module and configured to receive the light source driving signal output by the light source driving module and output a light source; a sensing unit electrically coupled to the light source driving module and configured to sense the light source driving signal output by the light source driving module; a lighting module electrically coupled to the power management module and the sensing unit, characterized by a power storage control function, and configured to receive the direct-current power output by the power management module, process the received direct-current power, output a direct-current power signal, store the direct-current power signal by means of the power storage control function, process the stored direct-current power signal whenever the sensing unit senses that the light source driving module does not output the light source driving signal, and output a lighting light source driving signal; and a second lighting unit electrically coupled to the lighting module and configured to receive the lighting light source driving signal output by the lighting module and output a light source.
