We present the composite luminosity function (hereafter LF) of galaxies for 80 Abell clusters studied in our survey of the Northern Hemisphere, using DPOSS data in the framework of the CRoNaRio collaboration. Our determination of the LF has been computed with very high accuracy thanks to the use of homogeneous data both for the clusters and the control fields and to a local estimate of the background, which takes into account the presence of large-scale structures and of foreground clusters and groups. The global composite LF is quite flat down to M^+5 and it has a slope alpha=-1.0 +/- 0.2 with minor variations from blue to red filters, and M^* = -21.9,-22.0,-22.3 mag (H_0=50 km s^-1 Mpc^-1) in g, r and i filters, respectively (errors are detailed in the text). We find a significant difference between rich and poor clusters supporting the existence of an LF's dependence on the environment.
