Description
[technical field]
The invention relates to a kind of light source module, and particularly be applied to LCD (liquid crystal display is LCD) as the module backlight (backlightmodule) of area source about a kind of.
[background technology]
LCD mainly comprises liquid crystal panel and module backlight, and module wherein backlight is the area source that is arranged at the liquid crystal panel rear.According to light source assembly, for example cold cathode ray tube or light emitting diode, the configuration difference, module backlight can be divided into down straight aphototropism mode set and side-light type module backlight.Side-light type module backlight is the side that light source assembly is arranged at LGP, makes that light beam that light source assembly sent can be from the side incident of LGP, again from the exiting surface outgoing of LGP.
Figure 1A is the explosive view of existing a kind of module backlight, Figure 1B is the part sectioned view of module backlight after assembling of Figure 1A, please refer to Figure 1A and Figure 1B, existing module 100 backlight comprises a LGP 110, two light source assemblies 120, two heat sinks 130, a reflector plate 112, several blooming pieces 150 and a framework 140.Module 100 backlight is the module backlight of bilateral side incident type, so the quantity of light source assembly 120 and heat sink 130 is all two.This two light source assembly 120 is made of a pair of cold cathode ray tube or a pair of light-emitting diode light bar, and is arranged at this respectively in the heat sink 130.
LGP 110 has an exiting surface 110a, a bottom surface 110b with respect to exiting surface 110a, one and connects exiting surface 110a is connected exiting surface 110a, bottom surface 110b and the first side 110c with the first side 110c and of bottom surface 110b the second side 110d.
Each heat sink 130 has a supporting walls 132, one first heat-conducting part 134 and one second heat-conducting part 136, and this is disposed at this respectively in the supporting walls 132 to light source assembly 120.First heat-conducting part 134 extends to the bottom surface 110b of LGP 110 from a side of the supporting walls 132 of correspondence.Second heat-conducting part 136 extends to the second side 110d of LGP 110 from first heat-conducting part 134 of correspondence.The structure of this heat sink 130 helps to increase the heat conduction approach of light source assembly 120.
It should be noted that; the heat that produces when being subjected to extraneous moisture or light source assembly 120 runnings easily owing to LGP 110 produces dilatancy; therefore prior art can keep a clearance D usually between LGP 110 and light source assembly 120; to avoid LGP 110 limited because of the expansion space after expansion; make whole LGP 110 buckling deformations; and the liquid crystal panel above being pushed through causes display quality impaired.
Yet, above-mentioned clearance D also makes relatively and can't closely cooperate between LGP 110 and the light source assembly 120, therefore after 120 groups of LGP 110 and light source assemblies stand, just may rock owing to external force makes LGP 110 produce, and because LGP 110 clashes into mutually with light source assembly 120 and produces different sound, and therefore LGP 110 also may be worn or damage with light source assembly 120.In addition, the briliancy of module 100 backlight also reduces because of the clearance D between LGP 110 and the light source assembly 110.
In order to solve the above problems, more existing prior aries are suggested in succession.TaiWan, China patent announcement M270369 and Taiwan patent publication No. 200720768, these prior aries adopt and on the framework of module backlight elastic device are set, and directly push against light emitting diode by elastic device, so that light emitting diode is near to LGP.Yet elastic device directly pushes against light emitting diode and may cause the heat radiation of light emitting diode bad, damages to such an extent as to shortening in the service life of light emitting diode even Yin Wendu are too high.
