  We present a new model of accretion disk where the disk luminosity is
entirely due to the reprocessing of hard radiation impinging on the disk. The
hard radiation itself is emitted by a hot point source above the disk, that
could be physically realized by a strong shock terminating an aborted jet. This
hot source contains ultra-relativistic leptons scattering the disk soft photons
by Inverse Compton (IC) process. Using simple formula to describe the IC
process in an anisotropic photon field, we derive a self-consistent solution in
the Newtonian geometry, where the angular distribution of soft and hard
radiation, and the radial profile of the disk effective temperature are
determined in a univocal way. This offers an alternative picture to the
standard accretion disk emission law, reproducing individual spectra and
predicting new scaling laws that fit better the observed statistical
properties. General relativistic calculations are also carried out. It appears
that differences with the Newtonian case are weak, unless the hot source is
very close to the black hole.
