Light-source module

A light-source module comprising:

• a light-source unit configured to provide a light beam;
• a first projection lens having an entrance pupil, wherein the light beam provided by the light-source unit can pass through the first projection lens via the entrance pupil;
• a first lens, wherein the first projection lens is optically coupled between the light-source unit and the first lens;
• a mirror wheel, wherein the first lens is disposed to guide the light beam to the mirror wheel, the light beam passes through the mirror wheel at a first time point to become a transmission light beam, and the light beam is reflected from the mirror wheel to the first lens at a second time point to become a reflection light beam, and the first time point is different from the second time point;
• a first light-guiding unit disposed to guide the transmission light beam;
• a second light-guiding unit disposed to guide the reflection light beam passing through the first lens, wherein the transmission light beam and the reflection light beam are respectively guided to the same side of the first lens by the first light-guiding unit and the second light-guiding unit;
• and
• a second projection lens disposed to receive the transmission light beam and the reflection light beam and having a first exit pupil and a second exit pupil, wherein the first exit pupil and the second exit pupil are arranged to be a row, and the transmission light beam and the reflection light beam respectively pass through the second projection lens via the first exit pupil and the second exit pupil.
