Optical film plate capable of adjusting light source

Abstract

The invention discloses an optical film plate capable of adjusting light source. One and another faces of a substrate are respectively provided with a first microstructure and a second microstructure, the first microstructure is a right triangular lens structure and is intersected in an array, and the intersection part respectively forms an unsymmetrical structure and a symmetrical structure; the second microstructure is an inverted triangular lens microstructure, and is arranged closely with equal distance. The optical film plate formed by the first microstructure and the second microstructure can reflect the light source generated by a plurality of light-emitting elements accommodated in a lighting device, a liquid crystal display device and a buried lighting device, so as to change the travel path of the light source and realize the aim of adjusting the light source.

Description

technical field [0001] The invention relates to an optical film capable of adjusting a light source, in particular to a kind of optical film which can change the path of a light source through the first microstructure and the second microstructure arranged on both surfaces of a base material, so that the light source A more focused technique when lighting. Background technique [0002] At present, the lighting source has been developed towards green energy, that is, low energy consumption, small size, light weight and long life, such as cold cathode tube (CCFL) or light-emitting diode (LED). The lighting brightness is brighter than traditional lamps, and the power consumption is lower than traditional lamps. Therefore, these multiple components have gradually replaced traditional lamps. [0003] The lighting devices on the market all use cold cathode tubes (CCFL) tubes or light emitting diodes (LED) tubes to achieve the effect of full lighting. However, although the lightin...

Problems solved by technology

[0003] The lighting devices on the market all use cold cathode tubes (CCFL) tubes or light emitting diodes (LED) tubes to achieve the effect of full lighting. However, although the lighting components are brighter than the illumination provided by traditional tubes, they When the lighting element is used for lighting, the brightness of the lighting produced will be inconsistent due to the structure of the lamp, which will cause the phenomenon of inconsistency in the brightness of the lighting source, which will lead to insufficient uniformity. In these cases, when the lighting device is installed, the The number of settings will be increased, and the distance between each group of lighting devices should not be too large, so as not to cause insufficient lighting brightness.

[0004] Therefore, when the lighting device is limited by the size of the lamp structure and the number of lighting sources, how to improve the lighting device will cause the problems of inconsistency in the brightness of the lighting source and insufficient brightness, which urgently need to be solved by the industry.
