| abstract |
The invention discloses a light emitting assembly. The light emitting module includes a plurality of laser elements and a setting unit. The plurality of laser elements are set to an on state having a logical value "m", an on state regarded as having a logical value "0", and an off state, where m is an integer of 1 or more. The setting unit sets the laser element in a state switchable to an on state, and sets the laser element in the on state regarded as having a logical value "0" before a timing at which the laser element in the state switchable to the on state is set in the on state having the logical value "m". |
