3LED Power consumption calculation
The effective value of LED current calculation is as follows
I LED I F * T / T
The effective value of LED voltage

4IC Power consumption calculation
Mains voltage and lamp bead voltage difference is the working voltage of
IC, the expression is as follows:
uIC(t ) u(t ) V(t ) 2Usin(2ft ) V(t )

IC power consumption is on the integral calculation, as follows
T2
PIC ( 2Usin(2ft) VF ) * I F dt / T

Lines of the inherent loss refers to the switching loss of IC, line loss, the
wastage of the rectifier bridge and other related loss these values cannot be
calculated, but by contrast experiment we can conclude that the depletion
approximation is a fixed value.
At this point, all the theoretical calculation about CYT1000B IC has been
completed, can make the graphical user interface to the above formula, which
can simulate the photovoltaic module in different lamp bead amount, different
feedback resistance, under the condition of different types of lamp bead the
change of the power and power efficiency, reference <CYT1000B application
