The current illumination numerical of node, and then regulation is determined based on the current illumination numerical of lighting nodes and default numerical value regulation step-length
Numerical value (regulation numerical value here is less than quantized values), utilizes the brightness for adjusting numerical value regulation lighting nodes.Regulation brightness it
Afterwards, new quantized values are got, regulation numerical value (this is determined based on the illumination numerical after regulation and default numerical value regulation step-length
In regulation numerical value be less than new quantized values), utilize adjust numerical value adjust lighting nodes brightness.By that analogy, using i.e.
When the method that follows realize the smooth lifting of brightness.For example, quantized values are 80%, and current value is 40%, if
It is 10% to preset step-length, then received after 80% this quantized data, the embodiment of the present invention is not adjusted directly in place,
But first adjust to 50%.After regulation brightness, new quantized values 70% are got, and current value is 50%, now
Directly regulation is not to 70%, but according to step-length regulation to 60%, and this is analogized, and realizes the smooth lifting of brightness.
Further, the embodiment of the present invention can specifically set the pulse for the brightness for adjusting lighting nodes according to regulation numerical value
Width modulated PWM count value, and then utilize the brightness of the PWM count value regulation lighting nodes set；Or, set according to regulation numerical value
The current value of the brightness of lighting nodes is adjusted, and then utilizes the brightness of the current value adjustment lighting nodes set.Still with above-mentioned
