Abstract

The invention relates to a combined type light guiding module with a high benefit light guiding function, which is composed of a plurality of light guiding structures, wherein, each light guiding structure comprises a light guiding body unit and a light reflecting micro structure unit, wherein, the light guiding body unit comprises a light guiding part, at least one indented light incidence part which is formed at one side end of the light guiding part and a containing part which is formed at one surface of the light guiding part. The light reflecting micro structure unit comprises a plurality of light reflecting micro structures which are respectively arranged in the containing part. All the light guiding structures are matched together to form a light guiding rod by the light guiding parts, form a light incidence groove which is arranged on the end surface at one side of the light guiding rod by the indented light incidence parts and form a light reflecting micro structure containing space which is hidden in the light guiding rod by the containing parts.

Description

technical field [0001] The invention relates to a light guide module, in particular to a combined light guide module with a high-efficiency light guide function. Background technique [0002] The design of a known light guide (Light Guide or Light Pipe) usually includes the following related considerations: [0003] 1. Light entrance face: [0004] When light is irradiated from a low-density transparent substance to a high-density transparent substance, reflected light and refracted light will be generated at the same time, and the sum of the energy of the reflected light and the refracted light is equal to the energy of the incident light. Such as Figure 1A and Figure 1B As shown, when the traveling direction of the light is perpendicular to the incident surface, the reflection ratio of the light rays (L10, L20) is the lowest. [0005] Such as Figure 1A As shown, the light incident end surface S1 of the traditional light guide rod is usually mainly plane due to the li...
