Description
Invention field
The present invention relates to a kind of protection structure of light source, relate in particular to a kind of protection structure that prevents light guide plate bump light source that is applicable to, for example LCD etc.
Technical background
LCD (LCD) for a kind of be not voluntarily can be luminous display, and must just can produce Presentation Function by adding the light source mode, light source for example, the backlight module that it combined is promptly played the part of the role of light source in LCD, be one of important key part and component of LCD.
In addition, general precise electronic product has quality acceptable degree more than through basic detection to guarantee its product in preceding all needs of listing, can safeguard consumer's rights and interests simultaneously.And backlight module is no exception, and also there be perfect quality control and the service system of a cover in all big enterprises for backlight module, uses the qualitative control control of carrying out backlight module closely.Especially at present under the environment of Market competition, each manufacturer to stipulate strict testing standard, shows the fiduciary level of its product quality especially, with the approval of winning the market, and this for example so-called reliability testing etc.
Please consult three-dimensional exploded view, and the sectional view of the protection structure of the existing light source of Fig. 2 of the existing backlight module of Fig. 1 simultaneously; wherein show a backlight module 9; and this backlight module 9 comprises stacked mutually following coverboard 91, light guide plate 92, prismatic lens 93, diffusion sheet 94 etc.; 911 of lateral margins in following coverboard 91 are assembled with a reflection shield 95 and a light cover 96 simultaneously; and be provided with a light source 97 in reflection shield 95, this light source is a fluorescent tube.
When above-mentioned backlight module 9 carries out so-called reliability testing, backlight module 9 is clashed into the direction of fixed angle, for example-the Y direction, in this simultaneously, check then whether the specified point on the backlight module 9 has the situation of breaking to produce, yet, when bump, light guide plate 92 in the backlight module 9 can produce the slippage action, and light guide plate 92 therefore slippage is moved and can be struck light source 97, cause light source 97 to break and influence that it is luminous, so cause whole backlight module 9 briliancy (luminance), be that the brightness that whole backlight module 9 seems is affected.
As shown in Figure 2, traditionally for preventing that light guide plate 92 from striking light source 97, can be bent with one folding piece 951 downwards in the both sides of reflection shield 95, and the tabs 951 of these both sides is positioned at the non-lighting electrode district 971 of light source 97 both sides, and these two tabs 951 can form the barrier effect of light guide plate 92, and can not influence the luminous of light source 97.
Yet the sheet metal that the common used thickness of the material of reflection shield 95 is thin is so even be bent with tabs 951 downwards, the strength when bump also is not enough to stop the slippage of light guide plate 92.In addition, reflection shield 95 cut off and bend the practice of tabs 951 downwards, also can cause the problem that stress concentrates and influence the intensity of integral inverted light shield 95, and the light source of light source 97 also can see through this place of cutting off and outwards disperse, cause the problem of optical anomaly.
In addition, reflection shield 95 cut off and bend the practice of tabs 951 downwards, except that can causing tabs 951 to produce the burr, also difficulty comparatively on making, real non-very good.
Except the above-mentioned practice, also have directly on light guide plate 92, directly to be stained with adhesive plaster, with the slippage that prevents light guide plate 92 and clash into light source 97, yet the viscous force of adhesive plaster is not sufficient to deal with so-called reliability testing.
In addition, also have directly directly to be cut into groove, and coverboard 91 conducts stop under using in the both sides of light guide plate 92, but the shape of the necessary design in addition of this practice light guide plate 92, and cause the optical anomaly phenomenon easily.
