Abstract: Provided is a lighting device that includes a light source assembly having at least two light sources with different light emitting characteristics, turned on and turned off independently to emit a light beam by one light source of the at least two light sources; a lens module, arranged on a light path of the light beam to receive the light beam; and an optical component, arranged on the light path to receive the light beam from the lens module, he optical component has a first light exiting portion and a second light exiting portion, and can move relative to the light source assembly, so that the light beam is exited from one of them, and a beam angle of the light beam exited from the first light exiting portion is different from the beam angle of the light beam exited from the second light exiting portion.

Abstract: Provided is a method and apparatus for controlling light attributes of a lighting device, and a lighting system and includes an indicator that receives an input, and sends to a control unit, a signal for switching light attribute of the lighting device; and the control unit determines whether a first switching signal or a second switching signal from the indicator is received during a light emission period after the lighting device is powered on, and if it is determined that the first switching signal is received, switching a current light attribute to another light attribute, or if it is determined that the second switching signal is received, switching the current light attribute to a light attribute indicated by the second switching signal such that when a specific light attribute is indicated by the second switching signal, the light attribute can still be adjusted with the first switching signal.
