Light guide element and light source device

Abstract

The invention provides a light guide element and a light source device. The light guide element comprises at least one first columnar part and at least one second columnar part, wherein the first columnar part is a part of a first reference cylinder; the second columnar part is a part of a second reference cylinder; and the first columnar part and the second columnar part are integrally molded, wherein the distance between the axes of the first reference cylinder and the second reference cylinder is less than the aggregation of the radiuses of curvatures of the first reference cylinder and the second reference cylinder.

Description

technical field [0001] The invention relates to an optical element and a light source device with the optical element, in particular to a light guide element and a light source device with the light guide element. Background technique [0002] Since the liquid crystal display panel does not have the characteristic of self-illumination, a backlight module must be placed under the liquid crystal display panel to provide the light source required by the liquid crystal display panel. Traditional backlight modules generally use cold cathode fluorescent lamps (CCFL) as the light source of the backlight module. [0003] However, with the advancement of semiconductor technology, light-emitting diodes (light-emitting diodes, LEDs) can achieve more and more power, and the intensity of light emitted is getting higher and higher. It has many advantages such as power saving, long service life, environmental protection, fast start-up, small size, etc., which makes the application level o...
