Abstract
The utility model provides a kind of high brightness ELED liquid crystal display backlight lamp bars, which includes：Pcb board, LED light and light guide plate, the lamp are arranged on pcb board in a vertical direction, and the circuit topological structure of the lamp is that the roads 4-6 are in parallel, and 20 or more lamps are designed with per road, meanwhile, perhaps light leakage, light guide plate use thickening design in order to prevent.The utility model can obviously increase lamp quantity by the way of lamp multi-channel parallel, to enhance backlight lamp bar brightness, and it is simple in structure, it is easily installed.
Description
Technical field
The utility model is related to a kind of optical devices, and in particular to a kind of LCD backlight display technology.
Background technology
Currently, have become the main product of FPD using all kinds of display terminals of LCD technology.Liquid
Crystal display screen belongs to passive and shines period, needs to show picture material by backlight.Since there are energy saving, rings by LED
The advantages of guarantor, long lifespan etc., present liquid crystal display product is all using LED as backlight.LCD backlight
Presentation mode is divided into two kinds of straight-down negative (DLED) and side entering type (ELED).Two kinds of backlight modes of DLED and ELED are compared, and are used
The display thickness of ELED modes is thinner, and volume smaller possesses certain market prospects.
The brightness for improving backlight, can improve the brightness of liquid crystal display.It is wide in some special occasions, such as outdoor business
It accuses, Medical image such as show at the fields, very high for the brightness requirement of display equipment.Commonly consumer display devices is common
ELED lamp bars are difficult to meet this high brightness requirement.For this purpose, the utility model proposes a kind of solutions of high brightness ELED backlight lamp bars
This problem.
Existing ELED liquid crystal displays backlight lamp bar includes 4 row's LED light, shares 4 row, 60 LED lamp, per LED lamp
For ellipse, the elliptical long axis of pressing of LED light substantially is that horizontal direction arranges, and 15 lamps can only be arranged by often arranging (road), be worked
Electric current 120mA, per LED light working voltage 3.4V, the luminous power of single lamp bar is 24.48W, and luminous power is restricted.
Utility model content
Goal of the invention：The purpose of this utility model is, to solve LCD backlight display field technical bottleneck, to provide a kind of high
Brightness ELED liquid crystal display backlight lamp bars, effectively improve LCD brightness while concise in technology is easy.
Technical solution：A kind of high brightness ELED liquid crystal display backlight lamp bars, it is characterised in that including pcb board, LED
Lamp, the LED light are that vertical direction is arranged on pcb board by elliptical long axis, and LED light described at least 20 LED is equipped with per road
Circuit topological structure be that the roads 4-6 are in parallel, lamp, the sum of the LED light on backlight lamp bar is at 80-120.
According to backlight lamp bar described in the utility model, preferably, 4 road parallel connection LED lamp on backlight lamp bar, the sum of lamp exists
80；It includes light guide plate, and the thickness of light guide plate is greater than general thickness, in order to prevent light leakage.Between keeping certain between lamp
Gap is convenient for heat dissipation.
Advantageous effect：Above-mentioned high brightness ELED liquid crystal display backlight lamp bars can be with due to being designed using multi-channel parallel
LED light quantity in lamp bar is obviously increased, to significantly increase the brightness of backlight lamp bar, and practical pcb board can be effectively save
Installation cost is easily installed.
Description of the drawings
Fig. 1 is the utility model LED lamp circuit connection figure
Fig. 2 is prior art routine ELED backlight lamp bar structural schematic diagrams
Fig. 3 is the utility model high brightness ELED backlight lamp bar structural schematic diagrams
Wherein：1 is pcb board, and 2 be LED light, and 3 be light guide plate.
Specific implementation mode
In order to know more about the utility model technology contents, spy lifts specific embodiment and is described with reference to the drawings.
Fig. 1 is the circuit diagram of the utility model installation, and A-K is the circuit of four paths of LEDs lamps；As shown in Fig. 2, before change, it should
Lamp bar has 60 LED lamps, and operating current 120mA, per LED light working voltage 3.4V, the luminous power of single lamp bar is
24.48W。
As shown in figure 3, after change, which has 120 LED lamps, operating current 120mA, per LED light working voltage
The luminous power of 3.4V, single lamp bar are 48.96W.
Using the ELED LCD brightness of the lamp bar by the 280cd/m before changing2Increase is increased to 520cd/m2, show
Show that device brightness improvement effect is apparent.
Pcb board (1) in figure, LED light (2), the LED light (2) are arranged in a vertical direction on pcb board (1), per LED
It is that 4 tunnels are in parallel that certain interval, LED light (2) circuit topological structure are kept between lamp (2), and 20 LED light are equipped with per road；It leads
Tabula rasa (3) is close to pcb board.
It should be noted that since the LED numbers in lamp bar increase, the circuit topological structure of LED light connection can become
Change.In this example, in parallel for 3 tunnels before change, 20 LED lamps of connecting per road；It is in parallel for 5 tunnels after change, 24 LED of connecting per road
Lamp.Further, since LED light is changed to after vertical direction puts, the depth of section that shines increases, in order to prevent light leakage, light guide plate
Thickness needs to increase.
The preferable specific implementation mode of the above, only the utility model, the scope of protection of the utility model not office
It is limited to this, any one skilled in the art is new according to this practicality in the technical scope that the utility model discloses
Type scheme and its inventive concept are subject to equivalent substitution or change, should all cover within scope of protection of the utility model.
Claims (2)
1. a kind of high brightness ELED liquid crystal display backlight lamp bars, which is characterized in that described including PCB plates, LED lamps
LED lamps are that the roads vertical direction 4-6 are arranged in parallel on PCB plates by the transverse of lamp, and at least 20 LED are equipped with per road
Lamp, the sum of LED lamps is at 80-120.
2. a kind of high brightness ELED liquid crystal display backlight lamp bars according to claim 1, which is characterized in that backlight
Item is equipped with the LED lamps that 4 tunnels are arranged in parallel, and the sum of LED light is at 80.
