[0044] see figure 1 , figure 2 and image 3 , the present invention provides a light combination device 1 for combining light emitted from multiple light source modules in different directions. Wherein, a groove 34 is provided on a side of the bottom plate 20 facing the gland 30 . The side plate 10 is connected to the bottom plate 20 and arranged around the bottom plate 20 to form a ring shape. The ring shape can be a ring shape or a polygonal ring shape. The side plate 10 can be integrally formed or assembled by multiple flat plates. The light rays are emitted along the direction perpendicular to the side plate 10. Gland 30 is installed on one end opening of side plate 10 and is opposite to bottom plate 20, to form a receiving space 50 in cooperation with side plate 10 and bottom plate 20, and the side of gland 30 near bottom plate 20 is provided with first elastic pad 91, The elastic pad 91 can press and fix the light-combining member 70 when the gland 30 is assembled. ...

[0060] see Figure 7 , Figure 8 and Figure 9 , different from the first embodiment, the side plate 10 provided in this embodiment is provided with a first card slot 16 and a second card slot 18, and the light combination device 1 includes a second elastic pad 92, which is fixed on The side plate 10 and the second elastic pad 92 cooperate with the slot to realize the position-limiting fastening of the light-combining element, so the side of the cover plate facing the bottom plate does not need to be provided with an elastic pressing element. The first card slot 16 is provided at the joint between the first side plate 11 and the third side plate 13 and at the joint between the second side plate 12 and the fourth side plate 14, the first card slot 16 can be used for the first light-combining sheet 72 , and the width of the first card slot 16 may be greater than the thickness of the first light-combining sheet 72 . The second card slot 18 is provided at the joint between the ...

[0063] see Figure 10 , Figure 11 and Figure 12 , different from the second embodiment, in this embodiment, the light combining member 70 is provided with a plurality of chamfers 76 , and the light combining device 1 further includes a plurality of third elastic pads 93 matched with the chamfers 76 . The chamfer 76 is defined at the corners of the first light-combining sheet 72 and the second light-combining sheet 74 , and the third elastic pad 93 is disposed in the slot of the side plate 10 . Specifically, two chamfers 76 are respectively formed on the sides of the first light combining sheet 72 and the second light combining sheet 74 near the pressing cover 30 . The third elastic pad 93 includes a first mounting portion 931 and a second mounting portion 933 perpendicularly intersecting each other. The shape of the second mounting portion 933 is the same as the cross-sectional shape of the groove. The third elastic pad 93 is roughly T-shaped. The four corners of the side...
