Optical component capable of regulating light condensation and fog

Abstract

The invention is an optical component able to regulate light gathering degree and haze, comprising: an optical substrate having a first surface area; forming several transmission bumps, where the area of the optical substrate occupied by the transmission bumps is a second surface area, and it reduces / increases the haze of the optical component by increasing / reducing the arrangement regularity, and increases / reduces the light gathering degree by increasing / reducing the ratio of the second surface area to the first surface area.

Description

【Technical field】 [0001] The present invention relates to an optical element, and in particular relates to an optical element capable of adjusting concentration and haze. 【Background technique】 [0002] Due to the limitation of conventional methods of manufacturing light sources or light-emitting elements, such as light emitting diodes (Light Emitting Diodes; LED) for generating point light sources, or cold cathode fluorescent lamps (Cold Cathode Fluorescent Lamp; CCFL) for generating line light sources, It is often impossible to form a flat light source with uniform brightness. Therefore, the traditional method is to add an optical element that can atomize the light source to the product that needs to produce a planar light source to homogenize the light source, and add an optical element with a light-concentrating function to the light source. Optical elements to increase the brightness of the front. [0003] A typical example is a backlight module in a liquid crystal di...

Problems solved by technology

[0004] However, the problem with the conventional optical elements is that the optical elements themselves absorb light, and the light source must pass through several optical elements to achieve a uniform and concentrating effect. Therefore, during the transmission of light, the light is often These optics are partially absorbing, thus reducing light usage

However, if the diffusion function and the light concentrating function are simply combined in a single optical element to reduce the light absorption of the optical element, the light concentration and haze of the single optical element cannot meet the requirements (haze means the transmission The ratio of the scattered luminous flux to the transmitted luminous flux that deviates from the square line of the incident light by the optical element, usually expressed as a percentage), makes further adjustments, thus greatly reducing the utilization of this single optical element
