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 request, the corresponding optimal value of different second lamplight components can be identical, also
Can be different.
For the second lamplight component, according to the concrete indicative function of lamplight component, its corresponding optimal value can be set.Example
Such as, status indicator lamp, tutorial light, display screen be both needed to more slightly higher than the light intensity of external environment, to reach corresponding instruction
During effect, corresponding optimal value is nonnegative number.Certainly, based on different practical application request, the optimal value can equally set
It is set to negative.
For example, when the optimal value of status indicator lamp be 5, the optimal value of tutorial light be 10, the optimization of display screen
It is worth for 5, when the corresponding digital signal of current light intensity is 50, the corresponding dutycycle of status indicator lamp is 55%, operation instruction
It is 55% that the corresponding dutycycle of lamp is 60%, the corresponding dutycycle of display screen.Therefore, when status indicator lamp is used, state refers to
Show that lamp works, and its luminosity is corresponding with 55% dutycycle.The like, luminosity during tutorial light work
Corresponding with 60% dutycycle, luminosity during display screen work is corresponding with 55% dutycycle.
