Description

MINI-LED three-dimensional reflection backlight unit

Technical Field

The utility model relates to a Mini-LED backlight unit technical field especially relates to a Mini-LED three-dimensional reflection backlight unit.

Background

The backlight is a light source located behind a Liquid Crystal Display (LCD) to provide the LCD with a uniform, stable and bright planar light source, so that the LCD can display images.

The existing patent publication No. CN216927934U discloses a mini LED backlight module with stacked reflector plates, which comprises a lamp panel, a plurality of LED chips and reflector plates; the reflector plate is attached to the front side of the lamp panel, and each LED chip is fixed on the lamp panel at a position corresponding to the opening of the reflector plate; at least one side of the lamp panel is provided with an extension part. The utility model discloses a lengthened reflector plate, extension lid cover at adjacent backlight unit edge and cover the piece, can compensate the shadow problem that the piece brought.

The reflecting plate is arranged in a plane, and visible light emitted by the LED chip light source is dispersed to the periphery, so that the problems of uneven light and shade of the light source, poor light condensation effect and darker whole light source are easy to occur.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a Mini-LED three-dimensional reflection backlight unit has solved current reflecting plate and has been the plane setting, and the visible light that LED chip light source sent is to dispersing all around, and it is inhomogeneous easily to have the light source light and shade, and the spotlight effect is relatively poor, the darker problem of whole light source.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

the utility model provides a Mini-LED three-dimensional reflection backlight unit, be in including lamp plate and normal line setting a plurality of LED lamp pearl on the lamp plate still includes the reflecting plate, be provided with the recess with a plurality of LED lamp pearl one-to-one on the reflecting plate, the bottom of recess is provided with the confession the spotlight hole that LED lamp pearl passed.

Further, the cross section of the groove is in an inverted trapezoid shape.

Further, the inner wall of the groove is coated with a reflective coating.

Further, the reflecting plate is integrally formed through hot pressing.

Because of the application of the technical scheme, compared with the prior art, the utility model has the advantages of it is following:

the utility model discloses a Mini-LED three-dimensional reflection backlight unit through setting up the reflecting plate into the body form structure, and the light that LED lamp pearl jetted out makes it finally assemble at the emmetropia direction emergence through the reflex action of the inner wall of the trapezoidal recess that falls to reach the effect of spotlight blast, the light-emitting of the three-dimensional reflection backlight unit of whole Mini-LED of messenger is more even.
