Light guide column and mobile communication terminal with same

Abstract

The invention discloses a light guide column and a mobile communication terminal with the same, which relate to the technical field of light processing and aim to effectively conduct light of a complicated conducting path. The light guide column comprises at least one first light guide column and one second light guide column which are mutually connected; the first light guide column is internally provided with a first light incident surface and a first light emergent surface which are mutually parallel; at least one first light reflecting surface is arranged between the first light incident surface and the first light emergent surface; the second light guide column is internally provided with a second light incident surface and a second light emergent surface which are mutually parallel;and at least one second light reflecting surface is arranged between the second light incident surface and the second light emergent surface. The mobile communication terminal comprises a shell, and the shell is internally provided with the light guide column. The light guide column can be used for conducting light.

Description

technical field [0001] The invention relates to the technical field of light processing, in particular to a light guide column and a mobile communication terminal with the light guide column. Background technique [0002] At present, LED (light emitting diode, light emitting diode) is becoming a mainstream device for backlighting due to its advantages of long life and small size, and is the most promising technology to replace traditional cold cathode fluorescent tubes in the future. [0003] The light from the LED backlight can be exported in the following two ways: [0004] The first way, such as figure 1 As shown, side lighting means that the light incident surface is perpendicular to the light exit surface. After the light emitted by the backlight enters the light incident surface, it is finally emitted from the light exit surface with the help of optical elements such as light guide plates and diffusion sheets. This method is currently Has been widely used in screen l...

Problems solved by technology

[0006] As we all know, the current design of mobile communication terminals is increasingly trending toward miniaturization. Therefore, for the second method, using light guide rods to transmit light, under limited space conditions, mobile communication terminals are used for indicator lights. The position distribution of the illuminated light source is subject to various restrictions, so that the distribution position of the light source cannot be directly opposite to the illumination position of the light source, and the distribution position of the light source is often scattered, forming a distributed light source, so that the light emitted by the distributed light source When it is transmitted to the indicator light, the transmission path of the light is more complicated, resulting in difficult light transmission and poor light output effect
