How to calculate the light received by a planet during a binary star eclipse?

I'm building up a spreadsheet on worldbuilding (Stars, Planets, Moons etc.) and i'm struggling to find an equation, or a group of equations to help me figure out the light received by a planet orbiting a P-Type Binary during both of its stellar eclipses.

I already have the light coming from the stars outside of the eclipses (represented in Joules), but searching for an equation to figure that out while one star is blocking the light of the other has alluded me. The closest i have come to finding an equation is one from the transit method, however that was intended to find the radius of exoplanets, so i don't think its quite relevant to what i'm looking for.

The specific numbers for the information needed to work this out isn't important - it's a spreadsheet, so they'll be changing/represented by cells. The specific units of measurement needed in this equation will be necessary however.
