Abstract
The invention discloses a combined LED (light-emitting diode) backlight source which comprises a backboard and an LED lamp strip, wherein the backboard comprises an upper backboard, a supporting strip and a lower backboard; the supporting strip is positioned between the upper backboard and the lower backboard; one end of the supporting strip is fixedly connected with the upper backboard, and the other end of the supporting strip is fixedly connected with the lower backboard; and the LED lamp strip is fixed at the lower end of the lower backboard. The combined LED backlight source disclosed by the invention has the advantages of light weight, low cost, high intensity, good heat dissipation effect and less possibility of deformation.
Description
Technical field
The present invention relates to a kind of LED-backlit source, be specifically related to the combined LED backlight that applies on the LCD TV a kind of.
Background technology
At present there is two kinds on whole galvanized sheet (SECC) type and whole aluminium section bar (AL-O) type in the LED-backlit source, and the pluses and minuses that above-mentioned two kinds of LED backboards exist are following:
Whole galvanized sheet (SECC) type (as shown in Figure 1): form by the zinc-plated backboard of integral body 1, stripe shape heat radiation aluminium substrate 2, LED lamp bar 3; Because backboard adopts galvanized iron sheet to constitute, its intensity is high, cost is low; But the monoblock backboard adopts galvanized iron sheet to exist radiating effect relatively poor, the problem that total quality is heavier, even between LED lamp bar and backboard 1, add a stripe shape heat radiation aluminium substrate 2 of accelerating heat radiation, its radiating effect is also very poor.
Whole aluminium section bar (AL-O) type (as shown in Figure 2): form with LED lamp bar 2 by whole aluminum backboard 1; Its monoblock backboard 1 adopts aluminium to process, since the aluminium sheet rapid heat dissipation, good heat dissipation effect, and total quality is lighter; But aluminium sheet intensity is low, and is yielding, and cost is high.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art, a kind of light weight is provided, cost is low, intensity is high, the combined LED backlight of not yielding and good heat dissipation effect.
Technical scheme: in order to realize above purpose, a kind of combined LED backlight of the present invention comprises: backboard and LED lamp bar, and said backboard comprises: go up backboard, support bar and following backboard; Said support bar is between last backboard and following backboard, and an end of support bar is fixedly connected with last backboard, and the other end is fixedly connected with following backboard; LED lamp bar is fixed in the lower end of backboard down.LED backboard according to the invention has been divided into three parts with the monoblock backboard: go up backboard, support bar and following backboard; Adopt support bar to connect between last backboard and the following backboard, reduced the overall weight of backboard, also reduced backboard consumptive material and production cost simultaneously, moreover, have living space between the support bar at interval, strengthened in the whole back plate to fluid space, radiating effect improves.
Going up backboard described in the present invention is galvanized iron sheet; Said support bar is zinc-plated iron bar; Said backboard down is an aluminium sheet; Last backboard adopts galvanized iron sheet, and support bar has adopted zinc-plated iron bar, has both guaranteed the bulk strength of backboard, has reduced again and has used material; Because backboard is connected with LED lamp bar down, has adopted aluminium sheet, the aluminium sheet rapid heat dissipation, light weight has further improved radiating effect, has alleviated the backboard quality, reduces greatly with respect to the back veneer material cost that adopts the monoblock aluminium sheet; So employing combinations thereof; Can either guarantee the bulk strength of backboard; Make it not yielding, guaranteed radiating effect again simultaneously, whole knockdown backboard has improved radiating rate through the following backboard of interval between the support bar and aluminum; Alleviate LED backboard total quality simultaneously, reduced the cost of raw material.
Support bar described in the present invention is one group, is fixed between backboard and the following backboard.Said support bar is preferably 3 or many, evenly distributes and is fixed between backboard and the following backboard; Evenly distributing makes each several part stressed evenly not yielding.
Beneficial effect: the present invention compared with prior art has the following advantages:
1, in the combined LED backlight of the present invention; Backboard is divided into three parts to be formed: go up backboard, support bar and following backboard; Connect through support bar between last backboard and the following backboard; Exist at interval between support bar and the support bar, can accelerate heat radiation, also reduced the gross mass of whole back plate simultaneously;
2, going up backboard and support bar among the present invention adopts galvanized iron sheet to guarantee the bulk strength of backboard; Owing to be connected with LED lamp bar, following backboard has adopted aluminium sheet, has accelerated radiating rate, has also alleviated the backboard quality simultaneously, and simultaneously with respect to the backboard that adopts the monoblock aluminium sheet, intensity improves, and material cost reduces greatly; So the employing combinations thereof can guarantee the bulk strength of backboard to make it not yielding, has also guaranteed radiating effect simultaneously, whole knockdown backboard has all improved radiating rate through the following backboard of interval between the support bar and aluminum.
