Description

A kind of leaded light backboard is gone into formula LED-backlit source

Technical field

The utility model relates to a kind of LED-backlit source, particularly relates to a kind of leaded light backboard and goes into formula LED-backlit source.

Background technology

Characteristics such as the LED-backlit source is meant the backlight that is used as LCDs with LED, compares with traditional CCFL (cold-cathode tube) backlight, and LED has low-power consumption, lower calorific value, brightness is high, the life-span is long.LED is the use that can replace colored filter as the advantage of backlight; The common LED backlight product is when assembling; The staggered assembling of the screens of LGP side screens and draw-in groove contraposition side, glue frame side upper and lower surfaces is adopted in the assembling of glue frame and LGP; Slip into glue frame groove from the LGP side, and during the assembling of LED assembly and glue frame, the LED assembly must be from the front alignment slot hyte dress.Above-mentioned assembling mode technical ability requires high, and packaging efficiency is low, and if poor expandability when needing increase the LED luminescence component because of demonstrations, then need be opened the glue frame mould in addition, causes the cost rising.

The utility model content

The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of simple in structure, easy to process reliable, packaging efficiency is high, the leaded light backboard that extensibility is strong is gone into formula LED-backlit source, satisfies the market demand to the LED-backlit source.

In order to achieve the above object; The technical scheme that the utility model adopts is: a kind of leaded light backboard is gone into formula LED-backlit source; Comprise successively from back-to-front: reflector plate, glue frame, LGP, diffusion sheet, time brightening piece, last brightening piece, anti-dazzling screen; And the LED luminescence component of side, said LGP dual-side is provided with along this plane, LGP place the outwards buckle of protrusion, and said glue frame both sides are provided with and the corresponding draw-in groove of the bayonet socket of LGP.

One side of said glue frame is provided with the integral type detent that the LED luminescence component is installed.

Compared with prior art, the utility model is simple in structure, easy to process reliably, significantly to improve packaging efficiency, and extensibility is strong, has reduced cost, has improved production efficiency, has satisfied the market demand in LED-backlit source now well.

The specific embodiment

Be elaborated with reference to accompanying drawing below in conjunction with embodiment, so that the technical characterictic and the advantage of the utility model are carried out more deep annotation.

The structural representation of the utility model is as shown in Figure 1; A kind of leaded light backboard is gone into formula LED-backlit source; Comprise reflector plate 1, LGP 2, glue frame 4, diffusion sheet 5, following brightening piece 6 successively, go up brightening piece 7, anti-dazzling screen 8 from back-to-front; And the LED luminescence component 3 of side, said LGP 2 dual-sides are provided with along plane, this LGP 2 place the outwards buckle 21 of protrusion, and said glue frame 4 both sides are provided with the bayonet socket 21 corresponding draw-in grooves 41 with LGP 2.

The LGP 2 that the utility model provided and the designs simplification of glue frame 4 packaging technology between LGP 2 and the glue frame 4; During installation; After 4 buckles 21 of said LGP 2 and 4 relative draw-in groove 41 contrapositions of glue frame 4, directly from the back side of product by after vertically install forward, 4 buckles 21 of LGP 2 are embedded in corresponding with it glue frame 4 draw-in grooves 41; Realization Fast Installation location, convenient efficient.

Because the one side along said glue frame 4 is provided with the integral type detent 42 that LED luminescence component 3 is installed; There is not boss 9 to do at interval in this detent 42; Therefore, glue frame 4 is when luminous group 3 of assembled LEDs, and LED luminescence component 3 directly is attached to the corresponding detent 42 of glue frame 4 from the back of product; Need not look like to assemble the alignment slot position from the front when conventional LED luminescence component 3 is installed, the product packaging efficiency is improved greatly.

Meanwhile, owing to do not have boss 9 to do at interval in the said detent 42, when the LED-backlit source need increase and decrease LED luminescence component 3 because of the requirement of brightness; Can directly increase and decrease LED luminescence component 3 and need not open the new glue frame 4 of glue frame 4 die production again corresponding one by one with LED luminescence component 3; Can realize the multiple batches of application of a mold, further save production cost, improve the product extensibility; Satisfy different occasions, different clients are to the multiple demand in LED-backlit source.

The content of mentioning in the foregoing description is not to be the qualification to the utility model, and under the prerequisite of the inventive concept that does not break away from the utility model, and any conspicuous replacement is all within the protection domain of the utility model.
