Title: LIGHT EMITTING MODULE
Abstract:
Provided is a light emitting module that can project a uniform volume of light over the entire incidence surface of an object of light projection. This light emitting module is used in a light projection device that projects light to the object of light projection while relatively changing, in one direction, the positional relationship between a light source unit and the object of light projection. On a substrate, a plurality of light emitting unit rows, in each of which at least one first light emitting unit and at least one second light emitting unit are arranged in one direction, are disposed by being arranged in a direction orthogonal to the one direction. Each of the first light emitting units and the second light emitting units are provided with a light emitting element which comprises an LED, and a sealed lens. The first light emitting units form a light distribution the peak of which is positioned on the light axes of the light emitting elements thereof, and the second light emitting units compensate the light distribution of the first light emitting units.
