Along with backlight and development Display Technique; Adopt the characteristics of LED lamp of electroluminescence very obvious, because of its have the life-span long, light efficiency is high, radiationless and advantage of low power consumption has been widely used in LCD backlight module and the self-luminous Display Technique at present.Show with backlight technology in, the lamp bar that adopts a plurality of LED lamps to form usually carries out luminous lighting or matrix demonstration as same block after will organizing the parallel connection of LED lamp bar then more.Will influence a block in appearance continuous demonstration difference like the damage that a LED lamp occurs owing to connect in the LED lamp bar that is provided with, this difference can be amplified by LED lamp bar, thereby influences backlight and display effect.
The improvement technology that has occurred in the prior art addressing the above problem.For example; On August 3rd, 2011 disclosed Chinese patent ZL201020579050.7; It provides LED-backlit lamp driver, LED liquid crystal module and display device, and said backlight circuit comprises the LED lamp bar that several are connected in parallel, and is distributed with a plurality of LED lamps on each lamp bar; LED lamp on the different lamp bars is with fixing ratio and position relation, and mutual interting is distributed in said LED-backlit lamp driver.The utility model makes ambient humidity, light and temperature backlight even through changing the configuration mode of each LED lamp in the LED-backlit lamp driver, has strengthened display effect, and has increased the service life of product.But one in the plurality of LEDs lamp of its series connection is in when opening a way, and the LED lamp on the series circuit at this LED lamp place all will not work, and this will influence whole backlight and picture demonstration.
For another example; Chinese patent ZL201020579050.7 relates to a kind of LED lamp with voltage-stabiliser tube; It by some LED lamp series connection in groups; Many group parallel connections back connects power supply, voltage-stabiliser tube of parallel connection on per 2～6 LED lamp in series connection LED lamp in groups, resistance of series connection in series connection LED lamp group in groups simultaneously.It can be implemented in use when can be by the voltage-stabiliser tube turning circuit during a certain LED lamp generation open fault in the lamp group; Thereby maintenance entire circuit conducting; But when open circuit appears in the wherein any LED lamp of 2～6 LED lamp parallelly connected with voltage-stabiliser tube; This moment, 2～6 LED lamp did not together all work, and will have obvious dark space.
The utility model content
It is a kind of reasonable in design that the utility model provides, and can effectively keep LED lamp driver and the module backlight and the display unit of the light and shade integral uniform property of backlight and display frame, guarantees the total quality of product.
The technical scheme that the utility model adopted is following:
A kind of LED lamp driver; Comprise two groups of LED lamp groups of connecting each other; Every group of LED lamp group comprises plural LED coupled in series lamp, and the said plural LED lamp of said two groups of LED lamp groups is staggered each other, and the two ends of per 2～6 LED lamp in every group of LED lamp group parallel connection one Zener diode.
In one embodiment, the said plural LED lamp of said two groups of LED lamp groups is staggered on a straight line direction.
In another embodiment, the voltage stabilizing value of said Zener diode is equivalent to 4～4.1 times of conducting voltage of LED lamp.
In the embodiment, the conducting voltage of said LED lamp is 3.0～3.3V again, and the minute-pressure value of said voltage-stabiliser tube is 13.0～13.49V/5mA.
The utility model also provides a kind of LED lamp module backlight, it is characterized in that said LED lamp module backlight comprises the LED lamp driver, and said LED lamp driver is above-mentioned arbitrary described LED lamp driver.
The utility model also provides a kind of LED lamp display unit, it is characterized in that said LED lamp display unit comprises the LED lamp driver, and said LED lamp driver is aforementioned arbitrary described LED lamp driver.
The plural LED lamp of two groups of LED lamp groups on this LED lamp driver is staggered in a straight line each other, and carries out open-circuit-protection at Zener diode of the other parallel connection of per 2～6 LEDs, when wherein open circuit appears in any LED lamp; The Zener diode conducting that it is parallelly connected and working; And the LED lamp on the LED lamp both sides of appearance open circuit though the position of arranging is adjacent, is not directly to be connected in series; Zener diode by different is protected; So still can operate as normal, make this viewing area not have obvious dark space, to the not obviously influence of whole picture.
The beneficial effect of the utility model is that this LED lamp driver and module backlight thereof and display unit are reasonable in design, can effectively keep backlight and light and shade integral uniform property display frame, guarantees the total quality of product.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to set forth.
Description of drawings
Fig. 1 is the structural representation of this LED lamp driver in the utility model specific embodiment.
The specific embodiment
The LED lamp driver of the utility model; Can comprise two groups of LED lamp groups of connecting each other; Every group of LED lamp group comprises plural LED coupled in series lamp; The plural LED lamp of these two groups of LED lamp groups is staggered each other, and the two ends of per 2～6 LED lamp in every group of LED lamp group parallel connection one Zener diode.And the plural LED lamp of these two groups of LED lamp groups is staggered on a straight line direction.
As shown in Figure 1, in a preferred embodiment of the utility model, this LED lamp driver comprises two groups of LED lamp groups 10 and 20 of connecting each other, and every group of LED lamp group includes plural LED coupled in series lamp 40.LED lamp in two groups of LED lamp groups 10,20 is staggered each other; Be the both sides of the LED lamp in every LED lamp group 10; What distribute is the LED lamp in another LED lamp group 20, and the both sides of the LED lamp in every LED lamp group 20, distribution be the LED lamp in another LED lamp group 10.And the plural LED lamp 40 of these two groups of LED lamp groups 10,20 is staggered on a straight line direction.Simultaneously, in every group of LED lamp group 10,20, the two ends of per 4 LED lamp parallel connection one Zener diode 30.When wherein open circuit appears in any LED lamp, its parallelly connected Zener diode 30 conductings and working, and the LED lamp on the LED lamp both sides of open circuit appears; Though the position of arranging is adjacent; But be not directly to be connected in series, protect, so still can operate as normal by different Zener diodes; Make this viewing area not have obvious dark space, to the not obviously influence of whole picture.
