Abstract
The invention provides a light emitting diode (LED) backlight module. The LED backlight module comprises a light guiding plate and a back plate which is used for fixing the light guiding plate; a reflector plate is arranged on the bottom portion of the light guiding plate in a paving mode, and a cylinder shape LED lamp is arranged at the bottom portion of the light guiding plate. The LED backlight module enables a light transmission path to be only half of the distance between adjacent two LED lamps by embedding the cylinder shape lamp in the light guiding plate. The LED backlight module has the advantages of being capable of reducing the light transmission path, further reducing the light energy loss caused by the long light transmission path, and enhancing light using rate.
Description
Technical field
The present invention relates to the liquid crystal TV set technical field, relate in particular to a kind of LED-backlit module.
Background technology
The LED-backlit module that generally uses at present is a kind of is straight-down negative, and a kind of is side entering type.
For the direct-light type LED backlight module, the LED lamp is spheric, is arranged on backboard, carries out reflection of light and refraction by the reflector plate on backboard and the diffuser plate that is arranged on LED lamp top.In order to improve the brightness of LED-backlit module, generally also use the more expensive brightening film sheet of price, increased manufacturing cost.For fear of the speck phenomenon, must guarantee that the light between the LED lamp fully mixes, guaranteeing will have enough distances between LED lamp and reflector plate and diffuser plate, and this makes the thickness of direct-light type LED backlight module be difficult to attenuation.
For the side entering-type LED backlight module, the backboard that it comprises LGP, is arranged on the LED lamp bar of LGP periphery or both sides and is used for lightguide plate fixing and LED lamp bar, the LED lamp is arranged on LED lamp bar.The backlight module of this structure, the light bang path is long, and optical energy loss is large.
Summary of the invention
For this reason, technical problem to be solved by this invention is: a kind of LED-backlit module is provided, can reduces because of the long optical energy loss that causes of light bang path, improve light utilization.
So, the invention provides a kind of LED-backlit module, comprise LGP and be used for the backboard of lightguide plate fixing, the LGP bottom is equipped with reflector plate, and is provided with columnar LED lamp in the LGP bottom.
Be provided with the reflector plate that is complementary with LED lamp shape below LGP bright dipping side panel above the LED lamp.
Described LGP bottom also is provided with the site to its scattering process of light.
Described LGP side is stained with reflector plate.
Be provided with the through hole that is complementary with columnar LED lamp on the reflector plate that lay described LGP bottom, columnar LED lamp is arranged on backboard, is arranged on the LGP bottom by described through hole.
LED-backlit module of the present invention, by embed columnar LED lamp in LGP, make the light bang path only for the distance between the two adjacent LEDs lamp half, reduced the light bang path, also with regard to having reduced because of the long optical energy loss that causes of light bang path, improved light utilization.
Description of drawings
Fig. 1 is the described LED-backlit module light guide plate of embodiment of the present invention part-structure schematic diagram.
The specific embodiment
Below, describe the present invention by reference to the accompanying drawings.
As shown in Figure 1, the present embodiment provides a kind of LED-backlit module, this backlight module comprises: LGP 21 and be used for the backboard (figure does not indicate) of lightguide plate fixing is equipped with reflector plate 22 in LGP 21 bottoms, and is provided with columnar LED lamp 23 in LGP 21 bottoms.The LED lamp is at least two.Therefore, the light bang path is only half of distance between the two adjacent LEDs lamp.
The present embodiment is illustrated as an example of cylindrical LED lamp example.
In order to prevent that the LED lamp from inlaying subregion obfuscation, affect visual effect, be provided with the reflector plate 24 that is complementary with LED lamp shape below LGP bright dipping side panel above the LED lamp.
In order to improve visual effect, make the light uniform emission out, also also be provided with the site 25 to its scattering process of light in LGP 21 bottoms.
The present embodiment also is stained with reflector plate 26 in described LGP side.
Preferably, be provided with the through hole (indicating in figure) that is complementary with columnar LED lamp on the reflector plate 22 of LGP 21 bottoms layings, columnar LED lamp 23 is arranged on backboard, is arranged on the bottom of LGP 21 by described through hole.
In sum, the described LED-backlit module of the present embodiment, by embed columnar LED lamp in LGP, make the light bang path only be half of the distance between the two adjacent LEDs lamp, reduced the light bang path, also with regard to having reduced because of the long optical energy loss that causes of light bang path, improved light utilization.
The above is only preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
