Abstract
A lighting system, which is composed of a redundant power supply and at least one luminaire with a lamp control module contained therein. The lamp control module includes at least one light source and a light control module. The light control module includes a current control unit, at least one switch unit, and a processing unit. The current control unit is to control the DC current. The switch unit is electrically connected to the light source and enables the DC current source to selectively control DC current to at least one light source. The processing unit is used to adjust value of DC current. The luminaire includes the lamp control module, housing and power lines. The redundant power supply contains at least one AC-to-DC converter module, and the redundant power supply provides constant DC power to at least one light control module of the luminaire.
