[0051] First, see figure 1 , figure 2 , Figure 5 and Image 6 as shown, figure 1 and figure 2 are respectively the three-dimensional combination diagrams of the light projection device U according to the first embodiment of the present invention, Figure 5 and Image 6 They are three-dimensional cross-sectional schematic diagrams of the light projection device U according to the first embodiment of the present invention. The present invention provides a light projection device U, which includes a heat dissipation unit 1 , a heat conduction interface unit 2 , a carrying unit 3 , a first reflection unit 4 , a light emitting unit 5 and a lens unit 6 . For example, the light projection device U can be applied to vehicle headlights, and the light projection device U can be combined with a reflective structure P set on the vehicle (refer to Figure 8 As shown, the reflective structure P is used in conjunction with the existing reflector lampshade installed on automobiles a...

[0072] First, see Figure 11 and Figure 12 as shown, Figure 11 and Figure 12 It is a three-dimensional combined schematic view of the light projection device U according to the second embodiment of the present invention. Depend on Figure 11 and Figure 12 and Figure 1 to Figure 4 It can be seen from the comparison that the biggest difference between the second embodiment and the previous embodiments is that the light projection device U provided by the second embodiment can directly utilize the positional configuration of the first light-emitting structure 51 and the second light-emitting structure 52 to produce lighting that conforms to vehicle lighting. The light distribution standard of the law does not need to configure the lens unit 6 and the carrying unit 3 . Further, if Figure 11 and Figure 12 As shown, the light projection device U may include a heat dissipation unit 1 , a heat conduction interface unit 2 , a light emitting unit 5 and a base unit 7 . It...

[0082] First, see Figure 15 as shown, Figure 15 It is a schematic diagram of light projection of the light projection device according to the third embodiment of the present invention. Depend on Figure 15 with and Figure 9 It can be seen from the comparison that the biggest difference between the third embodiment and the foregoing embodiments lies in that the installation position of the second light-emitting structure 52 in the light projection device U provided by the third embodiment is different from the foregoing embodiments. Further, if Figure 15 As shown, the light projection device U may include a thermal interface unit 2 , a light emitting unit 5 , a first reflection unit 4 and a lens unit 6 . It should be noted that, in order to make the drawings easy to understand, Figure 15 Only the main components are shown. That is to say, the light projection device U provided by the third embodiment may also further include a heat dissipation unit 1, a carrying unit...
