Description
Technical field
The present invention relates to a kind of light source group and reflector plate group thereof of light emitting diode, relate in particular to the light source group and the reflector plate group thereof that are used for the backlight liquid crystal display module.
Background technology
Because light emitting diode (LED) has characteristics such as little power consumption, efficient height, life-span length, does not also have environmental issues such as mercury pollution.And it backlight that is applied to various flat-panel screens can be obtained superior color representation, make light emitting diode being applied in display be subjected in recent years paying much attention to and research.
With regard to the main form of backlight module, promptly the lamp source position can be divided into side-light type structure and straight-down negative structure.The liquid crystal display applications product was mainly notebook computer and liquid crystal screen in the past, and that the characteristic demand of its backlight module mainly is is in light weight, volume is little and thin thickness, and the side-light type structure can meet this demand.But when the oversize backlight of exploitation liquid crystal display television by using, the important item of being considered then must be able to have enough video picture brightness, broad watch visual angle, distinct image contrast to reach long service life, in view of above-mentioned consideration, the straight-down negative structure just becomes the technology main flow of large scale liquid crystal display.
As shown in Figure 1, the light source group 10 of the direct type backlight module of available liquid crystal display comprises a reflector plate 11, a plurality of light emitting diode 12 and a circuit board 13.Described a plurality of light emitting diode 12 is fixed on this circuit board 13, and this reflector plate 11 also is fixed on this circuit board 13 again.This reflector plate 11 comprises a sheet material 111 and a plurality of through hole 112 of being located at this sheet material 111.A plurality of light emitting diodes 12 lay respectively in described a plurality of through hole 112, also promptly are exposed to through hole 112 on the sheet material 111.The light that light emitting diode 12 produces at first can go into to inject the diffuser plate (figure does not show) of top, and produces reverberation, and this sheet material 111 can also promptly reflect back the reverberation recycling to diffuser plate more then.
When the size of LCD is big more, then the size of the light source group 10 of light emitting diode and reflector plate 11 is also big more.About the making of reflector plate 11, it forms a plurality of through holes 112 by the direct punching out of porous drift on a sheet metal 111.In order to satisfy the opposite position accuracy requirement of through hole 112, so cost increases in Mold Making.Certainly will its unit cost need increase for making 11 of monolithic reflector plates in addition, and degree of difficulty is quite high on the assembling location with hundreds of above through holes 112.Also promptly, the minority hole is biased to be moved or defective then will be scrapped if having on the every reflector plate 11, and hundreds of through holes 112 also will be aimed at the light emitting diode 12 of correspondence respectively and just can finish assembling.
When light source group 10 adopts high-power light emitting diode 12, because of the light emitting diode 12 of high brightness can produce more heat.This heat can cause temperature to raise if accumulate on circuit board, therefore can make the brightness deepening on the contrary of light emitting diode 12.Dredge so the distribution of general high brightness LED 12 is comparatively wide, but also make the area source of light source group 10 present uneven phenomenon.For improving the uneven problem of this kind, just change high-power light emitting diode 12 into general lower powered light emitting diode 12, but need to increase the distribution density of light emitting diode 12 in the lump, so through hole 112 quantity also will increase on the reflector plate 11.Also promptly, the cost of above-mentioned reflector plate 11 and packing problem will be more thorny.
Summary of the invention
The invention provides a kind of light source group and reflector plate group thereof of light emitting diode, solve the cost and the packing problem of above-mentioned reflector plate by modular reflector plate group.Be more suitable for being applied to the large scale liquid crystal display.
