1 lumen = 1 candela per steradian.

1 candela = 1/683 watts per steradians (assuming 540nm light wavelength).

Assuming that the light is collected from a single steradian:

1 Lumen = 1 Candela -> = 1/683 Watt -> Watt = 683 Lumens

1 Joule = 1 Watt per Second -> Watt = Joule/Second

Hence:

683 Lumen = 1 Joule/Second

Under the above assumptions1 Lumen = 1/683 Joule/Second

There is no direct conversion between lumens and joules, as they measure different things. Lumens measure the amount of visible light emitted by a source, while joules measure energy. The relationship between the two depends on the light source's efficiency and spectral distribution.
