Abstract
The utility model relates to a direct illumination LED backlight module group with a light mixing apparatus, characterized in comprising an optical module group at the front side, a diffuser plate arranged at the back side of the optical module group, multiple columns of light bar PCBs at the back side of the diffuser plate, a reflecting sheet at the back sides of the light bar PCBs, a metal back plate at the back side of the reflecting sheet, each column of light bar PCB is provided with an LED light column, the front side of each column of light bar PCB and LED light column is provided with a light mixing lampshade fixed on the reflecting sheet parallel with the diffuser plate. The device can effectively shorten the light mixing distance of the direct illumination LED backlight module group, thus reaching the effect of reducing the whole thickness of the LED backlight module group.
Description
Technical field
The utility model relates to a kind of direct LED backlight module that has light mixing device, and particularly a kind of LED-backlit source module that has light mixing device is the backlight source module of a kind of high mixed light efficient, slimming.
Background technology
LCD or title LCD(Liquid Crystal Display), be the display device of planar ultra-thin.Because liquid crystal panel is non-spontaneous element, so need configuration module backlight.Existing a kind of direct-light type LED backlight module (it is constructed shown in Figure of description 1) is though compared with the more power saving of side entering type LED-backlit module, but for reaching the luminous even requirement in LED-backlit source, in the LED light-emitting area to being provided with enough spacings between the diffuser plate to form the mixed light chamber.Therefore, the direct-light type LED backlight module exists the thicker shortcoming of structure.
Summary of the invention
The purpose of this utility model is to provide a kind of direct LED backlight module that has light mixing device, and this device volume is little, and good uniformity and power consumption are little.
The utility model has the direct LED backlight module of light mixing device, it is characterized in that: comprise the optics module that is positioned at the front side, be positioned at the diffuser plate of optics module rear side, be positioned at the multiple row lamp bar PCB (Light bar PCB) of diffuser plate rear side, be positioned at the reflector plate of lamp bar PCB rear side, be positioned at the metal backing of reflector plate rear side, described each row lamp bar PCB is provided with LED lamp row, is provided with the mixed light lampshade with the front side of lamp bar PCB and is fixed on the reflector plate parallel with diffuser plate at the LED of each row lamp row.
Above-mentioned every row LED lamp is listed as by two or two and above LED, longitudinally evenly lays at interval.
In order to increase the mixed light efficient of LED, reduce BLU mixed light chamber distance, be provided with the mixed light lampshade structure.Described mixed light lampshade is the light-passing plastic material that is added with the mixed light agent, the cross section of mixed light lampshade be shaped as semicircle or half elliptic or triangle or regular polygon.The preferential practical semicircle in the cross section of present embodiment mixed light lampshade 9.
The direct LED backlight module that has light mixing device of the present utility model can effectively reduce the volume of LED-backlit module, realizes slimming.Its light mixing distance schematic diagram owing to increase the mixed light effect of mixed light lampshade, is eliminated mixed light dark space between the adjacent LED as far as possible shown in Figure of description 2, the LED light-emitting area is to expanding the distance of penetrating plate
Dwindle, thereby effectively reduce the volume of mixed light cavity, and then reduced the size of module backlight effectively.
The present invention is a kind of Novel LED light source mixed light design, can effectively the light mixing distance of direct-light type LED backlight module be dwindled, and then reach the effect of the integral thickness attenuate of LED-backlit module.

The specific embodiment
The utility model embodiment, as shown in Figure 3 and Figure 4, comprise the optics module 7 that is positioned at the front side, be positioned at the diffuser plate 8 of optics module 7 rear sides, be positioned at the multiple row lamp bar PCB (Light bar PCB) 11 of diffuser plate 8 rear sides, be positioned at the reflector plate 12 of lamp bar PCB 11 rear sides, be positioned at the metal backing 13 of reflector plate 12 rear sides, described each row lamp bar PCB 11 is provided with LED lamp row 10, is provided with mixed light lampshade 9 in the front side of the LED of each row lamp row 10 and lamp bar PCB 11 and is fixed on the reflector plate 12 parallel with diffuser plate 8.
Above-mentioned every row LED lamp row 10 are longitudinally evenly laid at interval by two or two and above LED 14.
The cross section of described mixed light lampshade 9 be shaped as semicircle or half elliptic or triangle or regular polygon.The preferential practical semicircle in the cross section of present embodiment mixed light lampshade 9.
Described mixed light lampshade 9 is for being added with the light-passing plastic material of mixed light agent.
The light mixing distance schematic diagram that the mixed light lampshade is not set as shown in Figure 4, be provided with mixed light lampshade 9 in this practical embodiment, its light mixing distance schematic diagram increases the mixed light effect of LED as shown in Figure 5, eliminate mixed light dark space between the adjacent LED, LED 14 light-emitting areas are to expanding the distance of penetrating plate 8 as far as possible
Dwindle, thereby effectively reduce the volume in mixed light chamber, and then reduced the size of module backlight effectively, it is little that its LED-backlit source module has a volume, slimming, improve the luminous efficiency of LED, the optical brightness height and the good uniformity of backlight, LED-backlit source module is low in energy consumption, is used for all can using on the backlight of the luminous display of inactive mode.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
