Abstract Irradiation of the photosphere by chromospheric flare continuum has been suggested as a mechanism of energy transport in white light flares. In this model the flare optical continuum originates from both the chromosphere (H fb emission) and the photosphere (H emission). Consequences of the irradiation model include different dependences on viewing angle of the two continuum components and reduction in minimum required chromospheric energy deposition rate, for a given visible light flare intensity, relative to models which assume only a chromospheric source. Testable predictions of the irradiation model, relating to specific effects on spatial variation and timing of flare emissions, are discussed.
