Abstract
A calibrating method of a light emitting device, which includes at least one light-emitting diode (LED) unit. The calibrating method includes the steps of inputting a brightness control signal to the LED unit, measuring a lighting brightness of the LED unit, and writing an initial relation of the brightness control signal and the lighting brightness into a memory unit. In addition, a light emitting device and a controlling method thereof are also disclosed.
Claims19
A calibrating method of a light emitting device, wherein the light emitting device comprises at least one light-emitting diode (LED) unit, the calibrating method comprising steps of:
- inputting a brightness control signal to the LED unit;
- measuring a lighting brightness of the LED unit;
- and
- writing an initial relation of the brightness control signal and the lighting brightness into a memory unit.
A control method of a light emitting device, wherein the light emitting device comprises at least one light-emitting diode (LED) unit and a memory unit, and the memory unit at least stores an initial relation of a brightness control signal and a lighting brightness for driving the LED unit, the control method comprising steps of:
- reading the initial relation from the memory unit;
- and
- determining a value of the brightness control signal for the LED unit according to a brightness requirement and the initial relation.
A light emitting device, comprising:
- at least one light-emitting diode (LED) unit controlling a lighting brightness thereof according to a brightness control signal;
- a memory unit storing an initial relation of the brightness control signal and the lighting brightness of the LED unit;
- and
- a control unit electrically connected to the LED unit and the memory unit, wherein the control unit determines a value of the brightness control signal according to a brightness required signal and the initial relation.
