1. An apparatus for controlling light attributes of a lighting device, wherein the apparatus for controlling light attributes of the lighting device comprises:
an indicator configured to receive an input of a user, and send, to a control unit, a signal for switching light attribute of the lighting device;
wherein the control unit is configured to:
(i) determine 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, switch a current light attribute of the lighting device to another light attribute, different from the current light attribute, in a stored light attribute table, or
if it is determined that the second switching signal is received, switch the current light attribute of the lighting device to a light attribute indicated by the second switching signal; and
(ii) in response to the lighting device being powered on, determine whether the second switching signal is adjusted by the user in a power-off state;
and if it is determined that the second switching signal is not adjusted in the power-off state, make the lighting device emit light according to a stored previous light-emitting light attribute of the lighting device; or
if it is determined that the second switching signal is adjusted in the power-off state, make the lighting device emit light according to a light attribute indicated by the adjusted second switching signal;
wherein when a specific light attribute is indicated by the second switching signal of the indicator, the light attribute of the lighting device is adjusted in accordance with the first switching signal of the indicator.
