optical device

Abstract

The invention provides an optical device which comprises the components of a structural light generating unit, at least one light transmission element and at least one optical coupling element. The optical coupling element is used for engaging the structural light generating unit and the light transmission element. A plurality of first light beams of the structural light output from the structural light generating unit are incident into the light transmission element for transmission and application. The optical device has advantages of improving light coupling rate of the optical device, and reducing size of the optical device.

Description

technical field [0001] The present invention relates to an optical device, in particular to an optical device with a light-conducting element. Background technique [0002] Optical fiber is a kind of light transmission tool, which is made of glass or plastic and other materials, mainly for the light beam to be transmitted in the way of total reflection, and the optical fiber has low loss, high bandwidth, light weight, small size, non-conductive, etc. Advantages, has been gradually applied in communications, medical, entertainment and other fields. For example, US Patent No. 2011 / 0069974 discloses that optical signals can be transmitted in the fabric by arranging optical fibers in the fabric. Also for example by HALO The wearable devices (such as belts and straps) sold by the company are equipped with light diffusion fiber (LDF) that can provide warning lighting, so users (especially old, young, women and children or people in motion) can use Wear the wearable device to i...

Problems solved by technology

[0003] However, the existing devices using optical fibers have at least the following three disadvantages: first, the light coupling rate between the light emitting source and the optical fiber used to provide the light beam entering the optical fiber is not good, so the light use efficiency is low; The optical fiber connector connecting the light source and the optical fiber occupies a lot of space due to its excessive size, and is not suitable for application in wearable products, especially for light, thin, and short applications; third, the prior art uses lenses to gather The light beam provided by the light source allows the light beam to enter the optical fiber, but because the lens has a certain thickness, it is difficult to effectively reduce the size of the device using the optical fiber, which is also one of the reasons why it is not suitable for wearable products
