Luminous body luminous flux measuring device

The invention discloses a luminous body luminous flux measuring device. The luminous body luminous flux measuring device comprises a spherical hollow photosphere, a luminous body moving table, a support for supporting the photosphere and the luminous body moving table, a reference lamp mounted on the inner side of a photosphere wall, and a photoelectric measuring instrument for measuring the lightintensity on the photosphere wall, wherein at least a photoelectric measuring port and a luminous body testing port are formed on the photosphere wall; a shield is arranged inside the photosphere; the shield is located between the photoelectric measuring port on the photosphere wall and the sphere center of the photosphere; the shield completely shields light directly emitted from the surface ofthe photosphere; a luminous body under measurement is arranged on the luminous body moving table; when a sliding frame moves towards the photosphere testing port, the luminous body can move towards the center of the photospher
