Problems solved by technology

The package body 122 used by the light-emitting diode 12 is semicircular. The package body 122 includes a substrate 125 and a semicircular reflective layer 124. The semicircular reflective layer 124 is used to increase the efficiency of light output from the front, but this method will cause other problems. Problems: (1) Because the light-emitting diode chip 121 is packaged on it, the

Abstract

The invention provides a light-emitting diode and a back light module. The light-emitting diode comprises a packaging body and a light-emitting diode chip. The packaging body comprises a substrate and a U-shaped case, one end of the U-shaped case is connected with the substrate, and the other end is in a circular structure. The light-emitting diode chip is arranged in the packaging body and is separated from the inner wall of the packaging body. In the invention, the light-emitting diode chip is placed at a distance from the inner wall of the packaging body by using the U-shaped packaging body, so that the number of light reflection is reduced, the light-emitting area is increased, and thus, the overall efficiency of the light-emitting diode is increased.

Description

technical field [0001] The invention relates to a light-emitting diode and a backlight module using the light-emitting diode, in particular to a light-emitting diode with a horseshoe-shaped package body and the backlight module of the light-emitting diode. Background technique [0002] Since the liquid crystal in the liquid crystal display panel does not emit light, in order to achieve the display effect, it is necessary to provide the liquid crystal display panel with a light source device, such as a backlight module, to realize the display function, so the light source is an important component in the backlight module. At present, notebook computers have begun to use a large number of light-emitting diodes (LEDs) as backlight sources. Light-emitting diodes have the advantages of long life, power saving, fast response, high reliability, environmental protection, and safety. The packaging methods are also different. See figure 1 , figure 1 Shown is a schematic diagram of a...
