1. A method for testing a light-emitting module comprising:
emitting light from a light-emitting module while rotating the light-emitting module around an axis, wherein the light-emitting module is in a housing configured to block external light;
sensing, with a plurality of photodiodes in the housing, a plurality of directional light intensities of the light emitted from the light-emitting module; and
outputting a light distribution map based on the directional light intensities.
