1. A light-emitting module, comprising:
a plurality of light-emitting elements, a micro lens array disposed on a light-emitting side of the plurality of light-emitting elements, and a low-refractive material layer disposed on a side of the micro lens array away from the light-emitting elements,
wherein a refractive index of the low-refractive material layer is smaller than a refractive index of the micro lens array; and
light emitted by the light-emitting elements is processed by the micro lens array and the low-refractive material layer to form a dot matrix light source which irradiates a plurality of preset opening regions disposed at intervals.
