Embodiment 1
[0040] Embodiment one, such as image 3 and Figure 4 As shown, the optical path assembly 13 includes two light-combining lens groups 131 and a reflector 132; the two light-combining lens groups 131 are respectively used to combine the lights of multiple colors emitted by the two lasers 12, and the two combined The optical lens groups 131 emit light beams towards the reflector 132 ; In this way, the structure of the optical path assembly 13 is simple, the cost is low, the volume of the laser projection light source is small, the structure complexity is low, and it is easy to realize.
[0041] In some embodiments, such as Figure 5 As shown, the first light exit area 121 of each laser 12,
[0042] The second light exit area 122 and the third light exit area 123 are both along the direction close to the reflector 132 (that is, image 3 and Figure 4 The directions X) in are arranged sequentially; such as image 3 and Figure 4 As shown, each light-combining lens group 131...
Embodiment 2
[0056] Embodiment two, such as Figure 8 As shown, the optical path assembly 13 includes two light-combining lens groups 131; the two light-combining lens groups 131 are respectively used to combine the light of multiple colors emitted by the two lasers 12, and the two light-combining lens groups 131 are both The light beam is emitted toward the light outlet 112 . In this way, the structure of the optical path assembly 13 is simple, the cost is low, the volume of the laser projection light source is small, the structure complexity is low, and it is easy to realize.
[0057] In the second aspect, some embodiments of the present invention provide a laser projection device, such as Figure 9 As shown, it includes a laser projection light source 1, an optical machine 2 and a projection lens 3 connected in sequence, the laser projection light source 1 is the laser projection light source 1 described in any embodiment of the first aspect above, and the optical machine 2 is used for...
