Abstract

The utility model relates to a splicing type backlight module structure, comprising a plurality of LED (light emitting diode) lamp panels, a plurality of cooling fins, a plurality of connecting pieces, a plurality of splicing frame bars and a plurality of liquid crystal supports; the cooling fins are adjacent to one another; the connecting pieces are fixedly arranged at a plurality of joint places between every two adjoining cooling fins; the splicing frame bars are spliced the peripheries of the jointed cooling fins; the LED lamp panels are arranged and fixedly locked at the inner sides of the jointed cooling fins; and the liquid crystal supports are fixedly arranged at the splicing frame bars. The structure is set by a mechanism which can be used for splicing and assembling the cooling fins, the connecting pieces, the splicing frame bars and the LED lamp panels so as to provide a high-brightness backlight module structure which can be optionally assembled to be special sizes, so that the manufacture cost of the module can be greatly saved.

Description

Spliced backlight modular structure

Technical field

The utility model relates to a kind of spliced backlight modular structure, refers to especially utilize spliced structure to be assembled into the high brightness backlights modular structure of specific dimensions.

Background technology

The backlight module of traditional commercial panel; Because its brightness is merely the 500-800 lumen mostly; So on backlight modular structure, then be that lamp plate directly is locked in the device brandreth, and see through contacting of brandreth and lamp plate; Among air, use the effect that reaches heat radiation with dissipation so that directly guide high temperature, the high heat of lamp plate when luminous.

Demonstrate the requirement of picture color vividness and definition for panel along with the consumer; Then also higher brightness of illumination must be provided with respect to backlight module; Also therefore; This also will certainly dissipation go out higher temperature and heat energy lamp plate when effect, so traditional device brandreth can't reach the high temperature of quick conduction lamp plate, the demand of high heat at short notice.And the employed device brandreth of backlight module of the commercial panel of the formula of habit; Then must look backlight module the actual size of the installing panel of will arranging in pairs or groups come other die sinking to make; So; The panel of the complete series size of panel vendor if arrange in pairs or groups, the die sinking manufacturing cost cost that then installs brandreth is then very huge.

Novel content

The purpose of the utility model provides a kind of spliced backlight modular structure; Its mechanism by the sliceable assembling of radiating fin, connector, winding moulding and LED lamp plate is provided with; A kind of backlight modular structure that can be assembled into specific dimensions arbitrarily is provided, and thermal conduction effect is good, and cost of manufacture is low.

The purpose of the utility model is achieved in that a kind of spliced backlight modular structure, comprising: several LED lamp plates, several radiating fins, several connectors, several winding mouldings and several liquid crystal supports; Those radiating fins then are the settings that is closely adjacent to each other; This connector is the joint that is fixedly set in this wantonly two adjacent radiating fin; Those winding mouldings are peripheries that installing is engaged in those radiating fins that spliced; Those LED lamp plates then are to install the inboard that locks in those radiating fins that spliced admittedly; This liquid crystal support then is fixedly set in this winding moulding.

The utlity model has higher, the benefit of heat conduction faster, therefore, need not to install additional again other auxiliary radiating device; And do not practise formula device brandreth yet and need distinguish the complicated program of die sinking production and high Mold Making expense, can significantly save the cost of Mold Making to the liquid crystal panel of different size.

The specific embodiment

Below sincerely with a specific embodiment, and assistant elaborates with graphic, so that the juror can have understanding further for the technical characterictic of the utility model.

See also Fig. 1～Figure 10, the spliced backlight modular structure 1 of the utility model comprises: several LED lamp plates 2, several radiating fins 3, several connectors 4, several winding mouldings and several liquid crystal supports 6.Those radiating fins 3 are the settings that are closely adjacent to each other; This connector 4 is the joints that are fixedly set in this wantonly two adjacent radiating fin 3; Those winding mouldings are peripheries that installing is engaged in those radiating fins 3 that spliced; Those LED lamp plates 2 then are to install the inboard that locks in those radiating fins 3 that spliced admittedly; This liquid crystal support 6 is fixedly set in this winding moulding.Wherein, the back side of this LED lamp plate 2 is provided with heat conduction pad 22; Those winding mouldings, then be to use horizontal moulding 51, vertically moulding 52, engage moulding 53 and corner moulding 54.And this spliced backlight modular structure 1 then can utilize those liquid crystal supports 6 to be installed on liquid crystal panel 71 with outside framework 72, and assembling becomes one side plate module 8.

This spliced backlight modular structure 1; Then can utilize those radiating fins 3, those connectors 4 and those winding mouldings; Come to be assembled into arbitrarily the mechanism assembly of fixing those LED lamp plates 2 of specific dimensions, the liquid crystal panel 71 of various sizes so that this spliced backlight modular structure 1 can be arranged in pairs or groups.And those radiating fins 3 then can provide more large-area heat dissipation region, compared to the plane device brandreth that generally is used for solid lock lamp plate, then have higher, the benefit of heat conduction faster, therefore, also need not to install additional other auxiliary radiating device again; And also do not practise formula device brandreth, the liquid crystal panel 71 that need be directed against the different size of being arranged in pairs or groups comes the complicated program of die sinking production respectively and high Mold Making expense.So this spliced backlight modular structure 1 quite is suitable for being applied in the backlight module design of high brightness, and can keeps light, thin mechanism size, and can significantly save the cost of Mold Making.
