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.

Method and apparatus for controlling light attributes of lighting device, and lighting system

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.

Lighting device

The present application discloses an illuminating device and a method for driving the illuminating device. The illuminating device comprises: an LED illuminating module; a mains supply operation module, comprising an LED driving unit; and a ballast operation module, comprising a simulation filament unit, a first detection unit, a second detection unit, a switch unit, a first start unit and a second start unit; wherein when the illuminating device is in a mains supply operation mode, the LED driving unit is used for driving the LED illuminating module; when the illuminating device is in a magnetic ballast operation mode, the first detection unit detects a voltage signal or frequency signal of the simulation filament unit and outputs a first detection signal, and after receiving the first detection signal, the first start unit enables the switch unit to be in a conducting state and drives the LED illuminating module; and when the illuminating device is in an electronic ballast operation mode, the second detection unit detects a voltage signal or frequency signal across both ends of the illuminating device and outputs a second detection signal, and after receiving the second detection signal, the second start unit enables the switch unit to be in a conducting state and drives the LED illuminating module.
