Abstract: An optical diffusing element includes a light emitting surface. The light emitting surface has microstructures, each microstructure has a border, the border of each microstructure is completely connected with the borders of the adjacent microstructures, each microstructure has a surface profile, and a functional formula of the surface profile is: s ( x ) = x 2 R + R 2 - ( κ + 1 ) x 2 ; s(x) represents the surface profile of each microstructure on an x-axis. The value x represents a vertical projection position of the surface profile on the x-axis. The value R represents a curvature radius of a vertex of each microstructure. The value κ represents a conic coefficient of each microstructure. The microstructures have the same value R and value κ. A light emitting assembly for three-dimension sensing includes the optical diffusing element and a light source. The optical diffusing element and the light emitting assembly for three-dimension sensing have the advantages of controlling light shape, light profile and simplifying design.

Abstract: A light-emitting device including a light-emitting unit and a second lens is provided. The second lens includes light-emitting surface, bottom surface, side surfaces and accommodation hole. The bottom surface is disposed opposite to the light-emitting surface, and the side surfaces are respectively connected to the light-emitting surface and the bottom surface. The accommodation hole passes through the second lens and accommodates light-emitting unit. A light-emitting module and a backlight module are also provided.
