Embodiment Construction

[0045] The technical means and effects used by the present invention to achieve the purpose will be described below with reference to the attached drawings, and the embodiments listed in the following drawings are only for auxiliary illustration, but the technical means of the present invention are not limited to the listed drawings .

[0046] See Figure 3A , the rhombic structure has good light-collecting characteristics in optical effect (reducing the divergence angle of the divergent light source); according to Snell's Law (Snell's Law), when the incident light 32 enters the prism 30, if the angle θ is greater than the critical angle of total reflection , then the incident light 32 will be totally reflected in the prism 30 ( Figure 3A Middle dotted arrow), if the angle θ is less than the critical angle of total reflection, then the incident light 32 will exit the prism 30 ( Figure 3A The solid arrow in the middle) will deviate from the normal again ( Figure 3A middle...

Abstract

The invention is an optical component and a light source device using it. And it has a first optical face and a second optical face able to receive an incident light and comprises a diffusion part and a light centralization part, where the diffusion part is made of photo-permeable material and can diffuse the incident light and the light centralization part is made of photo-permeable material and can centralize the incident light, and the diffusion part and light centralization part are butted mutually and located on the first optical face.

Description

technical field [0001] An optical component and a light source device, especially an optical component in which a diffusion component and a light collection component can be arranged on the same film layer, and a light source device using the optical component. Background technique [0002] In the current backlight module, optical films such as diffusion film, brightness enhancement film or polarization conversion film are mainly used together to achieve the purpose of uniformity and concentration of light. However, the sources of relevant components are currently controlled by foreign manufacturers. Although Taiwan’s display industry is booming, the key components of the backlight module industry have long been controlled by foreign manufacturers, resulting in low profits. In addition, the above-mentioned backlight module architecture uses a large number of diaphragms, which relatively results in lower module optical efficiency and higher module costs. Disadvantages such as...
