[0071] Example 1
[0072] figure 1 A perspective view of an optical system provided in an embodiment of the present application, figure 2 for figure 1 The top view of the optical system shown, image 3 for figure 1 Schematic diagram of the three-dimensional structure of the light guide shown in, Figure 4 for figure 1 Schematic diagram of the three-dimensional structure of the light guide shown in another view.
[0073] like Figure 1 to Figure 4 As shown, the present embodiment provides a light guide 10 for placing in the light-transmitting area 20 of the optical system. Light guides include:
[0074] the light port 11, for the light of the first light source 30 to pass through the light guide 10;
[0075] The light incident surface 12 is used to receive the light of the second light source 40 so that the light of the second light source 40 enters the light guide 10;
[0076] a reflective surface 13 for reflecting the light incident into the light guide 10 from the...

[0117] Example 2
[0118] Figure 10 A schematic structural diagram of a light guide provided in an embodiment of the present application, Figure 11 This is a top view of an optical system according to an embodiment of the present application.
[0119] like Figure 4 , 10 and Figure 11 As shown, the present embodiment provides a light guide 10 for placing in the light-transmitting area 20 of the optical system. Light guides include:
[0120] the light port 11, for the light of the first light source 30 to pass through the light guide 10;
[0121] The light incident surface 15 is used to receive the light of the second light source 80 so that the light of the second light source 80 enters the light guide 10;
[0122] the reflective surface 13 for reflecting the light entering the light guide 10 from the light incident surface 15; and
[0123] The light emitting surface 14 is used for the light reflected by the reflecting surface 13 to pass through the light guide 10 t...
Example Embodiment
[0164] Example 3
[0165] Figure 16 A schematic structural diagram of a light guide provided in an embodiment of the present application, Figure 17 This is a top view of an optical system according to an embodiment of the present application.
[0166] like Figure 4 , Figure 16 and Figure 17 As shown, the present embodiment provides a light guide 10 for placing in the light-transmitting area 20 of the optical system. Light guides include:
[0167] the light port 11, for the light of the first light source 30 to pass through the light guide 10;
[0168] The light incident surface 16 is used for receiving the light of the second light source 90 so that the light of the second light source 90 enters the light guide 10;
[0169] the reflective surface 13 for reflecting the light incident into the light guide 10 from the light incident surface 16; and
[0170] The light emitting surface 14 is used for the light reflected by the reflecting surface 13 to pass through the ...
