Abstract

The invention discloses a lateral light-emitting optical fiber and a backlight module with the same. The lateral light-emitting optical fiber comprises an optical fiber body, an arc-shaped groove is concavely formed in the side wall of the optical fiber body, and an anti-reflection film is arranged on the groove wall of the arc-shaped groove. Total reflection inside the optical fiber is destroyedby arranging the arc-shaped groove, and meanwhile, the anti-reflection film is arranged on the groove wall of the arc-shaped groove, so that the reflection effect of the arc-shaped groove on light canbe improved, the light which is destroyed and totally reflected in the optical fiber is refracted out from the other side, opposite to the side provided with the limiting groove, of the optical fiber, and lateral light emitting is further achieved.

Description

technical field [0001] The invention relates to the field of optical fiber technology, in particular to a side-emitting optical fiber and a backlight module with the same. Background technique [0002] Traditional optical fiber is composed of core, cladding and coating. The core completes the transmission of light, and the refractive index of the cladding and the core is different, so that the light can be transmitted in the form of total reflection in the core. [0003] However, in the prior art, the light transmission of the optical fiber is generally transmitted from one end of the optical fiber to the other end of the optical fiber, and the light output mode is single, which is not conducive to the diversified use of the optical fiber. [0004] Therefore, the prior art still needs to be improved. Contents of the invention [0005] In order to solve the problem of a single light output mode of the optical fiber in the prior art, the present invention proposes a side-e...
