The specific embodiment
For making object of the present invention, technical scheme and advantage are clearer, and by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Fig. 1, Fig. 2 are the structural representation of LGP of the present invention, as shown in Figure 1, 2, LGP of the present invention, includes light conducting plate body 1, in this light conducting plate body 1, be provided with the hole 10 of multiple storing illuminating sources, in hole 10, be provided with the snap-in structure that holds illuminating source.The surrounding in hole is hole wall.
Further, described hole can be through hole.
As one embodiment of the present of invention, as shown in Figure 3, light source comprises lamp body 20 and lamp socket 21.As shown in Figure 1, Figure 3, snap-in structure includes two blocks 11 on the hole wall top that is arranged at hole 10, and is arranged at respectively two plate washers 12 of two block 11 belows of the hole wall in hole 10, is formed with the gap 13 of accommodating illuminating source lamp socket between block 11 and plate washer 12.
For more clearly describing the structure of LGP of the present invention, as shown in Figures 1 to 5, be provided with x, y, z direction.Wherein, the horizontal direction that x direction is Fig. 1 to Fig. 5, the i.e. length direction of light conducting plate body.Y direction is the direction perpendicular to paper of vertical direction and Fig. 3 to Fig. 5 of Fig. 1 and Fig. 2, i.e. the width of light conducting plate body.Z direction is the vertical direction of Fig. 3 to Fig. 5 and Fig. 1 and Fig. 2 direction perpendicular to paper, i.e. the thickness direction of light conducting plate body 1.
Further, in the time that hole 10 is square through hole, two blocks 11 are that y direction or length direction are that x direction is symmetrical arranged along the width of light conducting plate body 1, so that light source is engagingly more firm.And in the time that hole 10 is manhole, two blocks 11 need only centered by the center of circle of the cross section in hole, Central Symmetry setting.No matter hole 10 is square through hole or manhole, preferably, two blocks 11 are that y direction is symmetrical arranged along the width of light conducting plate body 1, two blocks 11 preferably distribute in the x-direction, in light conducting plate body 1, between two holes 10, shared part does not arrange block 11 like this, can alleviate the stressed of this part LGP, make light conducting plate structure firmer.
Further, be formed with the accommodation space 14 of accommodating illuminating source lamp body between two plate washers 12, in the time light source being assembled to inlet hole 10, accommodation space 14 can be positioned at LGP by light source lamp body well.The set-up mode of two plate washers 12, completely identical with the set-up mode of two blocks 11, be also that y direction or length direction are that x direction is symmetrical arranged along the width of light conducting plate body 1.Or while being manhole in hole 10, two plate washers 12 can Central Symmetry mode arrange.
As one embodiment of the present of invention, the lamp body 20 of illuminating source is LED.On LED 20, be also provided with LED lamp socket 21; In this LED lamp socket 21, be provided with supply line being connected with LED etc.As shown in Figure 1, block 11 is positioned at the hole wall top in hole 10, symmetrical in the x-direction; Block 11 can be made with light conducting plate body 1 is one-body molded, also the structure of similar block 11 can be fixed on the hole wall in hole 10.Block 11 is made up of elastomeric material, in assembling, utilizes the elasticity of block 11 like this, LED can be pressed in gap 13 easily.And because block 11 recovers deformation after pressing, LED can not be removed from gap 13, has guaranteed the steadiness of LED.
As an alternative embodiment of the present invention, the opposite face of two blocks 11 is the inclined-plane less with light conducting plate body 1 thickness direction angle, and described inclined-plane and light conducting plate body 1 thickness direction angle are generally between 5 degree to 30 degree.Why so angle angle is set, and is mainly the convenience of having considered to put LED.Because above-mentioned block 11 has elasticity, can easily light source be slipped in hole by the inclined-plane of block 11, and after light source slips into, block 11 restores to the original state, block light source and skid off described hole 10 to prevent it.
As shown in Figure 3, keep the LED attitude of (in z direction) down, LED lamp socket 21 is pressed along the inclined-plane of block 11, because light conducting plate body 1 is made up of acryl/PC sheet material, LGP basis 1 and block 11 all have certain elasticity, therefore can be by LED lamp socket 21 smoothly by compressing into gap 13; , make LED lamp socket 21 fixing, thereby the LED being fixedly connected with LED lamp socket 21 is fixed the holding of the LED lamp socket 21 in gap 13 by block 11 and plate washer 12.It is constant that distance between LED 20 and plate washer 12 keeps.
Because LED is placed in the accommodation space 14 forming between two plate washers 12, its length does not exceed accommodation space 14, and therefore, the light that LED sends can fully be conducted into light conducting plate body 1, takes full advantage of the luminous efficiency of LED.
In Fig. 1, the length of the y direction of plate washer 12 equates completely with the length of the y direction of block 11.The length of the y direction of plate washer 12 also can be longer than the length of the y direction of block 11, can certainly be slightly shorter than the length of the y direction of block 11.As shown in Figure 2, the length of the y direction of plate washer 12 equates completely with the length of the y direction in hole 10, plate washer 12 in y direction across whole hole 10.Usually, the length of the x direction of the Length Ratio block 11 of the x direction of plate washer 12 is longer, so that more preferably make gap 13 hold LED lamp socket 21.
As shown in Figure 3, can make LED lamp socket 21 along gap 13 with y direction (in Fig. 3 perpendicular to the direction of paper, be the width of light conducting plate body) motion, make LED lamp socket 21 and LED move to block 11 as shown in Figure 1 and one end of baffle plate 12, because block 11 and baffle plate 12 remain with space in y direction and hole 10, can from this retaining space, take out in the z-direction again LED lamp socket 21 and LED.As shown in Figure 2, because the length of the y direction of the Length Ratio plate washer 12 of the y direction of block 11 is shorter, when LED lamp socket 21 and LED are moved to behind one end of block 11, can take out in the z-direction again LED lamp socket 21 and LED.
LED lamp socket 21 of the present invention can be made up of epoxy plate (FR-4).
As shown in Figure 4, in the present invention, the structure of block 11 can also be the structure of overshooting shape.The present invention is the shape of limit stop 11 not.
As shown in Figure 5, in the present invention, the opposite face of the accommodation space 14 being formed by plate washer 12 can also be set to inclined-plane.
The present invention has also recorded a kind of backlight, comprises LGP and the light source shown in earlier figures 1 to Fig. 5, and described light source is light emitting diode.
On above-mentioned light emitting diode, be also provided with lamp socket;
Described lamp socket is placed in described gap 13 by described snap-in structure; Described light emitting diode is placed in described accommodation space 14, does not exceed accommodation space 14.
The present invention has also recorded a kind of display unit, comprise display floater and aforementioned backlight, described display unit can be: any product or parts with Presentation Function such as liquid crystal panel, Electronic Paper, oled panel, LCD TV, liquid crystal display, DPF, mobile phone, panel computer.
Display unit of the present invention is especially liquid crystal display.Display floater is especially liquid crystal panel.
The above, be only preferred embodiment of the present invention, is not intended to limit protection scope of the present invention.
