Planck's law of thermal radiation is limited to equilibrium systems that have a definite temperature and do not carry any heat flux. We extend it to steady-state systems with a constant heat flux. The obtained formulas explicitly describe the spectrum of thermal radiation in every direction and provide a sound basis for the self-consistent analysis of radiative heat transport across interfaces, gaps, layered and other important structures.
