Embodiment Construction
[0038] figure 1 Middle: The upper figure shows that multiple red laser diodes 10 are installed on the substrate 1 and arranged in a plate shape to form a red laser light source plate 100. 100 emits multiple parallel laser beams 101, enters the converging lens group 2, and converges into a red color. The total light beam 102; the middle figure shows that a plurality of green laser diodes 20 are installed on the substrate 1 and arranged in a plate shape to form a green laser light source board 200, which emits a plurality of parallel laser beams 201, enters the converging lens group 2, and converges into a green total light beam 202; the figure below shows that multiple blue laser diodes 30 are installed on the substrate 1 and arranged in a plate shape to form a blue laser light source plate 300, which emits multiple parallel laser beams 301 and enters the converging lens Group 2, converging into a blue total light beam 302 .
