In particular, the optical space 34 is a prismatic cavity, i.e. the cross-section of the optical space 34 is polygonal.

As shown in fig. 3, in order to better eliminate the granular sensation on the surface of the optical portion 30, the following description will be made with reference to specific parameters. Specifically, the height h of the cross-section parallelogram of the optical space 34 is positively correlated with the distance L between the optical part 30 and the light source 22; similarly, the height H of the parallelogram positively correlates with the thickness H of the optical portion 30; the height h of the parallelogram is inversely related to the transmittance T of the optical portion 30.

Specifically, the length a of the bottom side of the cross-sectional parallelogram of the optical space 34 is positively correlated with the lateral width p of the embedded portion 31 of the optical portion 30; similarly, the light source 22 is spaced from the central line l of the substrate 21₁Is inversely related to the acute bottom angle alpha of the parallelogram.

As shown in fig. 3, the light ray (i) is a schematic diagram of an optical path without an optical space, and the light ray (ii) is a schematic diagram of an optical path with an optical space. When the light emitted from the light source 22 passes through the upper and lower bottom edges of the parallelogram, the light passes through a parallel plate, and the angular direction of the light is unchanged, while the horizontal direction is shifted to the right. The light passes through the first refraction surface of the parallelogram to be used as a first light emitting surface, the second refraction surface of the parallelogram is equivalent to a second light emitting surface, most of the light enters the optical part 30 again through the upper surface, and the brightness of the left side of the optical part 30 is reduced. After the light emitted from the light source 22 passes through the light mixing cavity and the optical space 34 for secondary light mixing, the granular sensation on the surface of the optical portion 30 is further reduced. That is, most of the light rays on the original left side of the surface of the optical portion 30 are shifted and attenuated to the right, so that the light rays which are concentrated originally are more diverged, and the light irradiation on the surface of the optical portion 30 is more uniform. In other embodiments of the present invention, the light source 22 may be disposed on the obtuse side of the bottom side of the parallelogram.

In other embodiments of the present invention, the optical space 34 is formed in the embedded portion 31. The embedded portion 31 and the protruding portion 32 are arranged to form the optical space 34, that is, the optical space 34 is arranged in the embedded portion 31 close to the protruding portion 32, so as to obtain a larger irradiation range.
