Light source device

Abstract

The invention relates to a light source device which comprises a substrate, a light emitting component, a first holder and a light guide component, wherein the light emitting component is arranged on the substrate; the first holder is provided with a base and an accommodating part; the base is provided with a surface and a through hole; the through hole is formed on the surface; the accommodating part convexly extends out of the surface of the base; the accommodating part surrounds the through hole at least partially; the light guide component comprises an end; the end is accommodated in the accommodating part of the first holder; and the light emitting component is positioned at one tail end surface of the light guide component through the through hole. The light source device provided by the invention has the beneficial effect that the light emitting angle can be elastically adjusted, therefore, the light source device is more convenient to use.

Description

technical field [0001] The invention relates to a linear light source of a light source device, in particular to a linear light source device. Background technique [0002] An image scanning device is a tool that optically converts an image, document or object into a digital image. The image scanning device usually includes a line-shaped light source, which illuminates a part of the scanned object. The reflected light passes through an optical module and is divided into three lights: red, blue and green. Image sensors (such as charge-coupled devices) convert red, blue, and green light into analog signals. The analog signal is converted into a digital signal by an analog / digital converter, and then output. Traditionally, a linear light source can be composed of a light guide column, a cold cathode lamp or a light emitting diode.
