Description
Technical field
The utility model relates to a kind of led light source device, relates in particular to a kind of led light source device that adopts particular form to be electrically connected LED.
Background technology
The scientific and technological information product is all towards light, thin, short, little target development at present, traditional display mode such as CRT crt display and LED display board or the like, all be limited by factors such as the excessive or power consumption of volume is very huge, be not easy to carry and carry, be difficult to satisfy user's actual demand, and the development of lcd technology just in time suits the trend of present information products, no matter be little, or the advantage such as zero radiation of right angle demonstration, low power consumption, volume, can both allow the user enjoy best visual environment.
LCD is to be basic module with the liquid crystal material, utilize the photoelectric effect of liquid crystal in the general electronic products,, see through the refracting characteristic of liquid crystal molecule again by the Control of Voltage of outside, and the rotatory power of light obtained the image of different brightness, and then reach the purpose of video picture.
LCD is as a kind of passivity display device, and itself can be not luminous, provides a kind of light source by the backlight that is positioned at its behind, side, and the light that this light source sends passes display floater, and makes LCD represent graph image.
In image display material such as LCD, backlight is positioned at the back of LCD panel, optical module and supports such as light source, LGP, astigmatism plate, diffusion sheet have generally been comprised, wherein, adopted luminous area source on a face, its light that sends is transmitted to diffusion sheet by diffuser plate or LGP, and light arrives prismatic lens through behind the diffusion sheet, reach liquid crystal board by prismatic lens again, make LCD represent graph image.
In image display material such as mobile phone display screen, backlight is positioned at the side (both sides or all around) of LCD panel, it comprises optical module and supports such as light source, LGP, diffusion sheet, and wherein, light source is made up of a plurality of illuminators of lining up a line, be referred to as line source, the light that light source sends is transmitted into diffusion sheet through after the reflection of LGP, through behind the diffusion sheet, arrive liquid crystal board again via prismatic lens, make LCD represent graph image.
Traditional LCD backlight adopts cold-cathode lamp (CCFL) as light source.But high image qualityization and cost degradation demand for development along with the backlight development, CCFL is difficult to meet the demands comprehensively, the advantage of LED is that color reducibility is good, life-span is long, and is not mercurous than environmental protection, drives simple, response speed is fast, environmental suitability is wide, and LED became the up-and-coming youngster in recent years, becomes the key content of backlight research and development.
Referring to Fig. 1, this is in the prior art, and powering at source plate backlight connects the schematic diagram of LED, has only shown the electrical connection of partial L ED here, and remaining LED also connects in an identical manner.
In Fig. 1, all LED are arranged in rectangular array on source plate backlight, the LED grouping of some is together in series in each row, for example LED 101, LED 102, LED 103, LED 104, LED 105, the LED 106 in first row is together in series, LED111, LED 112, LED 113, LED 114, LED 115, LED 116 in second row are together in series, or the like.
In Fig. 1, adopting altogether, the connected mode of anode is connected in the LED drive unit with the LED packet chain, wherein, this LED matrix has the negative pole that a positive pole and a plurality of quantity equal the LED packet chain, the positive pole of each LED packet chain all is connected in a positive pole of led driver, and the negative pole of each LED packet chain then is connected to the corresponding negative pole of led driver.
There is a problem in electric connection mode between this LED, promptly in a LED packet chain, can not the conducting electric current if one of them LED is out of order, so just can't be to any one the LED power supply in this LED packet chain, thereby this string LED can't be luminous, influenced the illumination effect of backlight, made that a corresponding panel region is secretly fallen on the display, visible this electric connection mode is not too reliable.
From as can be known above-mentioned, there is more serious reliability problems in the method for this electrical connection LED of the prior art, not only in backlight, and in other field that LED uses, for example as lighting source etc., also has such reliability problems.
The utility model content
The purpose of this utility model is that the method that provides a kind of LED to be electrically connected solves the problems referred to above, the mode of using specific grouping and series connection is together in series the LED grouping of some, make one or more LED in the LED packet chain and one or more LED of other LED packet chain be placed in position adjacent, if when LED packet chain for some reason can not be luminous like this, the situation that display secretly falls can not occur in a big way, therefore can significantly increase the reliability of system.
According to an aspect of the present utility model, a kind of led light source device is provided, it comprises a plurality of LED, described a plurality of LED comprises a plurality of LED groupings, described each LED grouping comprises a LED or continuously arranged a plurality of LED that is electrically connected with series system, and wherein, described a plurality of LED groupings are carried out respective electrical respectively according to its mutual alignment relation and connected, with the influence to described led light source device of the fault that reduces single led grouping, described respective electrical connects to comprise and is connected in series or is connected in parallel.
