  We present a 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 ultrarelativistic leptons scattering the disk soft photons by
Inverse Compton (IC) process. Using a simple formula to describe the IC process
in an anisotropic photon field, we derive a self-consistent angular
distribution of soft and hard radiation in the Newtonian geometry. The radial
profile of the disk effective temperature is also univoquely determined. The
high energy spectrum can be calculated for a given lepton distribution. This
offers an alternative picture to the standard accretion disk emission law. We
discuss the application of this model to Active Galactic Nuclei, either for
reproducing individual spectra, or for predicting new scaling laws that fit
better the observed statistical properties.
