Something else doesn’t make sense here...
practically ,
voltage drope between LED terminal is 4.66v even i exceed the Vcc to 9 or 10V??
Vbe=1.49V
Vbc=0.54V
What's the intended circuit purpose, switch or current source?
Where did you get the assumed current gain of 30? Are you aware of the large type variations of actual current gain?
transistor 2n2222 is wrong picture
the main picture above with TIP160 work as switch
The old TIP160 transistor is a Darlington:The value of hFE in the calculation is way too high. I suggest 20 or so.
For a transistor in saturation assume Ic=10*Ib.I make a modification

This is a rule if thumb for non darlingtons.For a transistor in saturation assume Ic=10*Ib
