Problems solved by technology

[0004] The first peak E1 of the previous proposal is "hidden" inside the second peak E2, which will somewhat affect the light concentrating effect of the entire optical film, thereby affecting the luminance and luminous flux of the optical film. room for improvement

Embodiment Construction

[0023] Preferred embodiments of the present invention will become apparent from the following description accompanied by the accompanying drawings.

[0024] refer to figure 2 The optical film of the present invention comprises: a transparent base layer 1, a first prism layer 2 continuously arranged on the transparent base layer 1, and a second prism layer 3 integrally formed and connected on the first prism layer 2.

[0025] The first prism layer 2 is formed by sandwiching a pair of mirror surfaces 21, 22, which taper upwards to form a first peak 23, and a first peak angle θ is formed between the pair of mirror surfaces 21, 22. 1 , for example can be made to 104 °, but the present invention is not limited thereto.

[0026] The second prism layer 3 is formed by sandwiching another pair of mirror surfaces 31, 32, and tapers upward (sharply) to form a second peak 23, and the second peak angle θ is formed between the pair of mirror surfaces 31, 32. 2 , for example can be 90° or...

Abstract

The present invention discloses an optical thin film of multi peak and partial peak multistage type optical collecting, as well as a method to manufacture the multistage type optical thin film. The present invention comprises a transparent basic level, and a plurality of multistage type prism levels arranged connectively on the basic unit. The multistage type prism levels form a plurality of peaks, and each peak assumes a tapering and narrowing structure towards the light direction (for example upwardly), thus being able to enhance the light concentrating effect, and increasing the brightness of the optical thin film and the luminous flux.

Description

technical field [0001] The invention relates to an optical thin film and a manufacturing method thereof, in particular to a multi-peak and off-peak multi-stage light-collecting optical thin film and a manufacturing method thereof. Background technique [0002] The present invention is an improvement of the applicant's previous US patent (Application No.: 11 / 366,870) "multi-stage light-collecting optical film and its manufacturing method" (hereinafter referred to as the previous application). [0003] The representative figure of this prior art optical film 4 is shown as the present application figure 1 , the prism 6 is arranged on the substrate film 5, and each prism 6 is adjacently connected to form a prism array, each prism 6 includes at least a lower prism assembly 61 and an upper prism assembly 62, and the lower prism assembly 61 is connected to On the substrate film 5, and the lower prism assembly 61 includes a pair of lower prism surfaces 6a and 6b, the axes of the sl...
