Patent granted for light-guide optical element with multiple inclined surfaces
A recently granted patent (Publication Number: US11885996B2) discloses a light-guide optical element designed to efficiently guide light within a transparent body. The element includes multiple inclined surfaces with reflective layers that enable the input light to be reflected sequentially, resulting in output light emitted from the first surface of the body. The configuration ensures that light travels within the body without being reflected by the first or second surfaces, enhancing the overall efficiency of the optical element. The patent specifies the angles and distances between the inclined surfaces, as well as the reflectance percentages of the reflective layers, to optimize the performance of the light-guide optical element.
Furthermore, the patent details additional features such as a third reflective layer on the third inclined surface and a transparent member coating the first and second surfaces of the light-guide body. The inclusion of these elements aims to further enhance the reflective properties and durability of the optical element. The transparent member can be made of materials like glass, plastic, or resin, providing flexibility in the design and manufacturing process. Overall, the patented light-guide optical element offers a novel and efficient solution for guiding light within a transparent body, with specific configurations and reflective properties to optimize its performance in various applications.
