Description
Technical field
The utility model relates to a kind of backlight module, particularly the illuminated LED-backlit module of a kind of side.
Background technology
Liquid crystal indicator comprises a liquid crystal panel and a backlight module.This liquid crystal panel is comprised of layer glass substrate therebetween one liquid crystal layer, and the up and down outer surface of glass substrate posts polaroid; Because liquid crystal panel itself is not luminous, therefore need backlight module to provide bright dipping uniform surface light source system for it.The light source that backlight module uses mainly contains CCFL (Cold Cathode Fluorescent Lamp, cathode fluorescent tube) and LED, wherein LED has the characteristics of pollution-free, long-life, vibration resistance, shock resistance, low energy consumption, High Efficiency Luminescence, is widely used at present.The illuminated LED-backlit module of side comprises: a metal backing is used for holding and support of optical diaphragm and LED lamp bar; A LGP, this LGP have at least one incidence surface and an exiting surface; At least one LED lamp bar is oppositely arranged with the LGP incidence surface, and this LED lamp bar has an exiting surface towards this LGP incidence surface, is arranged at least a side of this LGP; One reflector plate, many blooming pieces and a glue frame.For the stability and the life-span that ensure LED, it has higher requirements to heat radiation, so have higher requirement for the heat dissipating method of middle large scale LED-backlit module.At present, the method that the illuminated LED-backlit module of side solves heat radiation is: LED lamp bar is attached on the aluminium radiating board with heat conductive silica gel, with screw LED lamp bar is locked on the aluminium radiating board, aluminium radiating board and the backboard that then will attach LED lamp bar are fixed together again.The heat that LED produces can be derived fast thus.The method that is connected and fixed of this kind LED lamp bar and aluminium radiating board needs many small screws, and also will be to LED lamp bar and aluminium radiating board punching, and cost is higher, and the efficient that assembly and disassembly are changed is low.
The utility model content
Utility model purpose: for the problem and shortage of above-mentioned prior art existence, the purpose of this utility model provides the illuminated LED-backlit module of a kind of side, reduce the cost that is fixedly connected with of LED lamp bar and aluminium radiating board, improve assembling, the removal efficiency of LED lamp bar and aluminium radiating board, make things convenient for contraposition, the installation and removal of LED lamp bar and aluminium radiating board.
Technical scheme: for realizing above-mentioned utility model purpose, the technical solution adopted in the utility model is the illuminated LED-backlit module of a kind of side, comprise LED lamp bar, aluminium radiating board and buckle, described LED lamp bar be provided with for described aluminium radiating board contraposition and the first groove that is fixedly connected with, described aluminium radiating board is provided with second groove corresponding with described the first groove, described buckle places the first groove and the second groove, fixing described LED lamp bar and aluminium radiating board.
For further improving radiating effect, described LED lamp bar and aluminium radiating board can attach with heat conductive silica gel.
The material of described buckle preferably has flexible metal material, to guarantee that buckle can rely on elastic force to block LED lamp bar and aluminium radiating board.
Beneficial effect: LED lamp bar is fixedly connected with the form of aluminium radiating board with buckle, has replaced traditional screw fixed form, and the cost of manufacture of buckle is lower than screw, and buckle compares screw and have the efficient advantage of easy installation and removal, improves the packaging efficiency of module.Implementation: the corresponding groove that is used for placing buckle is set at LED lamp bar and aluminium radiating board, LED lamp bar and aluminium radiating board are attached with heat conductive silica gel, and then be stuck with buckle, guarantee the applying of LED lamp bar and aluminium radiating board closely, the aluminium radiating board that will attach at last LED lamp bar uses screw locking on metal backing, guarantee that the heat that LED produces can be transmitted on the metal backing by aluminium radiating board fast, guarantee the heat radiation of LED, safeguard its High Efficiency Luminescence and life performance.
Description of drawings
Fig. 1 is the LED lamp bar of the illuminated LED-backlit module of prior art side and the fixed connection structure schematic diagram of aluminium radiating board;
Fig. 2 is the LED lamp bar of the illuminated LED-backlit module of the application's side and the fixed connection structure schematic diagram of aluminium radiating board;
Fig. 3 is the local enlarged diagram of part in Fig. 2 circle.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, after LED lamp bar 1 usefulness heat conductive silica gel (not shown) and aluminium radiating board 2 attach, lock LED lamp bar and aluminium radiating board with screw 3 again, make LED lamp bar and aluminium radiating board location, fixing.
As shown in Figures 2 and 3, LED lamp bar 1 be provided with for aluminium radiating board 2 contrapositions and the first groove 4 that is fixedly connected with, aluminium radiating board is provided with second groove 5 corresponding with the first groove 4, and buckle 6 places the first groove and the second groove, fixed L ED lamp bar and aluminium radiating board.After LED lamp bar 1 usefulness heat conductive silica gel (not shown) and aluminium radiating board 2 attach, again with snaps into position and fixing, saved screw, and installation and removal are convenient, efficient, be conducive to LED lamp bar and aluminium radiating board contraposition, guarantee every LEDs on the LED lamp bar and the correct position contraposition on the LGP (not shown).
Claims (3)
