Abstract

The invention provides a light supply apparatus and a manufacturing method thereof. The light supply apparatus comprises a base, a light-emitting chip and a sealed mirror body, wherein the light-emitting chip is arranged on the base; the sealed mirror body is covered on the base and surrounds the light-emitting chip; the external surface of the sealed mirror body mainly comprises an internal ring convex surface and an external ring convex surface; the external ring convex surface surrounds the outside of the internal ring convex surface to form a ring form; the internal ring convex surface is surrounded into a conical space with narrow bottom and wide opening; the light-emitting chip is positioned in the projection range of the internal ring convex surface on the base; and partial light rays generated by the light-emitting chip are directly reflected to the external ring convex surface by the internal ring convex surface, and are directly emitted or refracted at the position of the external ring convex surface to leave the sealed mirror body.

Description

【Technical field】 [0001] The present invention relates to a light source device and its manufacturing method; specifically, the present invention relates to a light source device capable of avoiding excessive concentration of light and its manufacturing method. 【Background technique】 [0002] The display panel and the panel display device using the display panel have gradually become the mainstream of various display devices. For example, various panel display screens, flat-screen TVs for home use, flat-panel monitors for personal computers and laptop computers, display screens for mobile phones and digital cameras, etc., are all products that use a large number of display panels. In particular, in recent years, the market demand for liquid crystal display devices has grown significantly. In order to meet the functional and appearance requirements of liquid crystal display devices, the designs of backlight modules used in liquid crystal display devices are also increasingly ...
