1. A light source module, comprising:
a light-emitting element, comprising a light-emitting surface;
a light-guiding plate, comprising a light-incident surface, wherein the light-guiding plate is disposed such that the light-incident surface faces the light-emitting surface; and
a filter, disposed between the light-emitting surface and the light-incident surface, and a center wavelength of a reflection band of the filter falls in a range of 570 nm to 590 nm,
wherein the light-emitting element emits a first light having a first color temperature from the light-emitting surface, the first light is filtered into a second light having a second color temperature after the first light passed through the filter, the light-incident surface of the guiding plate receives the second light, and the first color temperature is lower than the second color temperature,
wherein the first color temperature is between 2500 K and 3800 K and
wherein the second color temperature is between 6000 K and 7000 K.
