"
 Please insert external resistance (R1, 1/4W) between LED anode terminal and VLEDVcc to limit the LED average
  consumption current for current limitation.
 
In case of using R1, formula is as follows :
LED resistance value : R1 [&], LED average consumption current : ILED [mA],
Supply voltage : VLEDVCC [V], minimum necessary of irradiant intensity Ie1 [mW/sr]
 
R1 = 110 ?(VLEDVCC  1.45) / Ie1 5 [&] 
ILED = Duty ?(VLEDVCC  1.36) / (R1+4) [A]
Duty : LED duty at emitting
 
 Please set up to be ILED < 180[mA] (Duty d 25%).
