DIFFUSER, LIGHT-EMITTING DEVICE, AND SENSOR MODULE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240027656 titled 'DIFFUSER, LIGHT-EMITTING DEVICE, AND SENSOR MODULE

Simplified Explanation

The abstract describes a diffuser that consists of a lens array with multiple single lenses. Each single lens satisfies two expressions, one representing an aspheric lens and the other defining a relationship between the conic constant and the ratio of the radius of curvature to the pitch of the single lenses. When a ray of light parallel to the optical axis of the single lens is incident on it, it does not strike the edge part of the lens.

  • The diffuser includes a lens array with multiple single lenses.
  • Each single lens satisfies an expression representing an aspheric lens and a relationship between the conic constant and the ratio of the radius of curvature to the pitch of the single lenses.
  • Rays of light parallel to the optical axis of the single lens do not strike the edge part of the lens.

Potential applications of this technology:

  • Lighting systems: The diffuser can be used in lighting fixtures to distribute light evenly and reduce glare.
  • Imaging systems: It can be utilized in cameras or projectors to improve image quality and reduce aberrations.
  • Display devices: The diffuser can enhance the uniformity and clarity of displays, such as LCD screens or LED panels.

Problems solved by this technology:

  • Uneven light distribution: The diffuser ensures that light is evenly spread across a surface, eliminating hotspots or dark areas.
  • Glare reduction: By preventing rays from striking the lens edge, the diffuser minimizes glare and enhances visual comfort.
  • Aberration correction: The aspheric lenses and the defined relationship between the conic constant and lens parameters help correct optical aberrations, resulting in improved image quality.

Benefits of this technology:

  • Improved lighting quality: The diffuser provides uniform and diffused light, enhancing the overall lighting experience.
  • Enhanced visual comfort: By reducing glare, the diffuser makes it more comfortable for users to view displays or illuminated environments.
  • Higher image quality: The aspheric lenses and aberration correction contribute to sharper and clearer images in imaging systems.


Original Abstract Submitted

a diffuser includes a lens array including multiple single lenses. each of the multiple single lenses satisfies expression (1), which contains a conic constant and represents an aspheric lens, and expression (3), which defines a relationship between the conic constant k and the ratio r/d of a radius of curvature r of the single lens to a pitch d of the single lenses. a ray of light incident on the single lens and parallel to an optical axis of the single lens does not strike an edge part of the single lens.
