Wherein, YiFor the duty of the corresponding pwm signal of i-th kind of second lamplight component at least one lamplight component
Than X is the digital signal, biFor the corresponding optimal value of i-th kind of second lamplight component.
In detail, based on different practical application requests, the corresponding optimal value of the second lamplight component of difference can be identical, also
It can be different.
For the second lamplight component, according to the specific indicative function of lamplight component, its corresponding optimal value can be set.Example
Such as, status indicator lamp, tutorial light, display screen are both needed to more slightly higher than the light intensity of external environment, to reach corresponding instruction
When effect, corresponding optimal value is nonnegative number.Certainly, based on different practical application requests, which can equally be set
It is set to negative.
