Abstract
The utility model discloses a kind of LED-backlit module, the metal backing matched with described center including center, and the lamp bar matched with described metal backing, the medial wall phase clamping of described metal backing and described center surrounding, the surrounding of described metal backing is provided with flange, described lamp bar is pasted on the medial wall of described flange, and the lateral wall of described flange is provided with the positioning convex matched with described center.The setting of metal backing, effectively increases the area of dissipation of lamp bar, meanwhile, the design of turnup structure, facilitates coordinating of the installation of lamp bar and backboard and center so that easy to assembly fast.
Description
Technical field
This utility model relates to back light model setting technology field, particularly relates to a kind of LED-backlit module.
Background technology
Industrial instrumentation equipment, graphical interfaces many uses liquid crystal module of digital equipment at present, and backlight module is as liquid crystal
One vitals of module, plays considerable effect especially for the size of liquid crystal display screen brightness and the uniformity of display,
When conventional structure backlight module is applied in liquid crystal module, often use low-power LED.When low-power LED normally works, produce
Heat little, it is not necessary to special radiator structure derives the heat that LED produces, and is replaced by by low-power LED high-power
During LED, heat dissipation problem has become a bottleneck the most scabrous.
Utility model content
The purpose of this utility model is to provide a kind of good heat dissipation effect, Stability Analysis of Structures reliable LED-backlit module.
For reaching this purpose, this utility model by the following technical solutions:
A kind of LED-backlit module, the metal backing matched with described center including center, and with described metal backing
The lamp bar that plate matches, the medial wall phase clamping of described metal backing and described center surrounding, the surrounding of described metal backing sets
Being equipped with flange, described lamp bar is pasted on the medial wall of described flange, and the lateral wall of described flange is provided with and described center phase
The positioning convex coordinated.
Wherein, also include being layed in the reflectance coating of described metal backing inner surface, being layed in described reflectance coating upper surface
Light guide plate, it is layed in the diffusion barrier of described light guide plate upper surface, is layed in the lower bright enhancement film of described diffusion barrier upper surface, Yi Jipu
It is located at the upper bright enhancement film of described lower bright enhancement film upper surface.
Wherein, described lamp plate includes flexible printed circuit board and uniform along described flexible printed circuit board length direction
LED lamp bead.
Wherein, described lamp plate includes aluminium base and along the uniform LED lamp bead of described aluminium base length direction.
Wherein, described metal backing uses aluminium sheet integrated punching molding.
Wherein, described center uses plastic cement one-body molded.
The beneficial effects of the utility model: this utility model includes the metal backing that center matches with described center, with
And the lamp bar matched with described metal backing, the medial wall phase clamping of described metal backing and described center surrounding, described gold
The surrounding belonging to backboard is provided with flange, and described lamp bar is pasted on the medial wall of described flange, and the lateral wall of described flange is arranged
There is the positioning convex matched with described center.The setting of metal backing, effectively increases the area of dissipation of lamp bar, meanwhile,
The design of turnup structure, facilitates coordinating of the installation of lamp bar and backboard and center so that easy to assembly fast.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of LED-backlit module.
Detailed description of the invention
Below in conjunction with the accompanying drawings 1 and further illustrate the technical solution of the utility model by detailed description of the invention.
This LED-backlit module, the metal backing 2 matched with described center 1 including center 1, and with described metal backing
The lamp bar 3 that plate 2 matches, the medial wall phase clamping of described metal backing 2 and described center 1 surrounding, the four of described metal backing 2
Being provided with flange 21 week, described lamp bar 3 is pasted on the medial wall of described flange 21, and the lateral wall of described flange 21 be provided with
The positioning convex 22 that described center 1 matches.
Also include being layed in the reflectance coating 4 of described metal backing 2 inner surface, being layed in leading of described reflectance coating 4 upper surface
Tabula rasa 5, be layed in described light guide plate 5 upper surface diffusion barrier 6, be layed in described diffusion barrier 6 upper surface lower bright enhancement film 7, with
And it is layed in the upper bright enhancement film 8 of described lower bright enhancement film 7 upper surface.
As the first preferred embodiment of the present utility model, described lamp plate includes flexible printed circuit board and along described flexibility
The LED lamp bead 31 that printed circuit board (PCB) length direction is uniform.This mode designs, and can pass through heat-conducting glue along the medial wall of flange by lamp body
Integrally it is layed in the medial wall of flange, and then realizes the location of lamp bar.
As the first preferred embodiment of the present utility model, described lamp plate includes aluminium base and along described aluminium base length side
To uniform LED lamp bead 31.This structure designs, and in advance lamp bead is welded to aluminium base, will be welded with the aluminum base of lamp bead the most again
Plate is fixed to the medial wall of flange, the lamp bar that this mode designs, good heat conductivity, good heat dissipation effect.
Metal backing 2 in the present embodiment uses aluminium sheet integrated punching molding.Described center 1 uses plastic cement one-body molded.
Know-why of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
By novel principle, and the restriction to this utility model protection domain can not be construed to by any way.Based on explanation herein,
Those skilled in the art need not pay performing creative labour can associate other detailed description of the invention of the present utility model,
Within these modes fall within protection domain of the present utility model.
