Multicolor light mixing module

A multicolor light mixing module suitable for providing a multicolor laser beam to a laser projection apparatus, the multicolor light mixing module comprising:

• a first laser set comprising a plurality of first lighting units and a plurality of second lighting units arranged in sequence, the plurality of first lighting units emitting a first color light, and the plurality of second lighting units emitting a second color light;
• a second laser set adjacent to the first laser set and comprising a plurality of third lighting units arranged in sequence, the plurality of third lighting units emitting a third color light;
• a first light-mixing member disposed at a position opposite to the first laser set and the second laser set and having a first refractive surface, a reflective surface, and a second refractive surface, wherein the first refractive surface is disposed obliquely to reflect the first color light to travel along a first light-mixing axis and allow the second color light to pass through and be incident to the reflective surface, the reflective surface is disposed obliquely to reflect the second color light to pass through the first refractive surface and travel along the first light-mixing axis, the second refractive surface is disposed obliquely to reflect the third color light to travel along a light-exit axis, and the light-exit axis is coplanar with the first light-mixing axis;
• and
• a second light-mixing member disposed on the first light-mixing axis and the light-exit axis, for reflecting the first color light, the second color light, and the third color light to form a multicolor laser beam along a second light-mixing axis.
