Light guide, objects that use light guide, and method for assembling the same

Abstract

Disclosed herein are a light guide, a light source housing assembly that uses light guide, a light engine that uses light guide, a method for making light guide, and a method for assembling light source housing assembly. The light guide may include a light rod and a lens. The light rod comprises a first end and a second rod, wherein the first end is used for receiving light while the second end is provided with a light exit, and the lens is connected with the second end in an optical coupling manner. The 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. A light source may be provided for the light guide, and the light guide receives the 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
