A light guide, object containing the light guide, and manufacturing and assembling methods thereof

Abstract

The invention provides a light guide, a light source set containing the light guide, a light engine containing the light guide, a manufacturing method of the light guide, and an assembling method of the light source set. The light guide includes a light rod and a lens. The light rod has a first end and a second end, wherein the first end is used for receiving light, the second end serves as a light exit, and the lens is optically coupled to the second end. The single piece light guide may be formed using injection molding. The light guide may have one or more regions between the light rod and the lens. A housing may be provided for the light guide. The housing may have an opening that physically supports the light rod. The light guide may be provided with a light source and receives light from the light source.

Description

technical field [0001] The present invention relates to a component for receiving light, and in particular to a light guide, a light source kit containing the light guide, a light engine containing the light guide, a manufacturing method of the light guide, and a light source kit assembly method. Background technique [0002] Light guides and light guides are widely used. The light guide can receive light from a light source and transmit the light over a certain distance with minimal light loss. For example, light from at least one LED can be transmitted through the light guide. to another place. Light guides can also manipulate light in specific ways, for example, light guides can combine light of different colors, or light guides can collimate light. One of the possible applications of the light guide is to install it in a projector. [0003] From a technical point of view, it is beneficial to miniaturize projectors and related devices equipped with light guides, and on...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a light guide and a device containing the light guide in view of the defects that the device with the light guide in the prior art is difficult to assemble and may fall due to shaking and cause the light guide to be misaligned. The object and its manufacturing and assembly method, the light guide can be firmly set in the intended position, and prevent the misalignment of the light guide during use
