Due to the thinning trend of LCD TVs, the light guide plate 31 is designed to be thinner and thinner. As shown in FIG. greater than the area of the light incident surface 311 of the light guide plate 31, resulting in part of the light emitted by the light emitting diodes 20 not entering the light guide plate 31 through the light incident surface 311, that is, the light emitted by the light emitting diodes 20 does not completely enter the light guide plate 31, which will cause energy loss

The invention relates to a light-emitting diode, a light stripe comprising the light-emitting diode and a side-light backlight module. The light-emitting diode comprises a shell, a light-emitting surface, at least one wafer and at least one side wall, wherein the shell is provided with an accommodating space, at least one wafer is configured in the accommodating space and used for generating light, the at least one side wall is arranged on the surface of the shell, the light-emitting surface is formed at an opening of the accommodating space, an inner side surface is arranged on each side wall and used for reflecting the light of the at least one wafer, and the top of the at least one side wall is higher than the light-emitting surface. Therefore, the light can be more concentrated in thevertical direction to improve the intensity of light in the vertical direction.
Description
technical field [0001] The invention relates to a light-emitting diode, a light bar containing the light-emitting diode, and a side-light backlight module, in particular to a light-emitting diode with a side wall, and a light bar and a side-light backlight module including the light-emitting diode. Background technique [0002] Referring to FIG. 1 , it shows a perspective view of a conventional light bar (Light Bar). The light bar 1 includes a substrate 10 and a plurality of LEDs 20 . The light emitting diodes 20 are arranged on the substrate 10 , and each of the light emitting diodes 20 includes a housing 21 , a light emitting surface 22 , at least one chip 23 and an adhesive material 24 . The casing 21 has an accommodating space 211 , and the adhesive material 24 is filled in the accommodating space 211 . The adhesive material 24 includes at least one fluorescent powder (for example, fluorescent powder that can emit white, red, blue, yellow light, etc.). [0003] The li...
