Light isn't heat (heat is the kinetic energy of the disordered movement of particles). Evaporation normally occurs because molecules have enough of this disordered kinetic energy to break from their intermolecular bonds and enter the air. In this case, light is physically knocking small clusters of several molecules into the air together in an ordered way.
