Let Φ be an N-function, then the Jung constants of the Orlicz function spaces LΦ[0,1] generated by Φ equipped with the Luxemburg and Orlicz norms have the exact value:

(i) If FΦ(t) = tφ(t)/Φ(t) is decreasing and 1 < CΦ < 2, then

JC(L(Φ)[0,1]) = JC(LΦ[0,1]) = 21/CΦ-1;

(ii) If FΦ(t) is increasing and CΦ > 2, then

JC(L(Φ)[0,1]) = JC(LΦ[0,1])=2-1/CΦ ,

where CΦ= limt→+∞ tφ(t)/Φ(t).
