Preferably, also be provided with some the 2nd LED back to reflector plate of the described end on the described LED lamp bar, the lumen value of a described LED is higher than the lumen value of described the 2nd LED.
Preferably, described LED lamp bar is fixed on the side plate of described module shell.
Preferably, the side plate of described module shell is provided with the mounting groove that holds described LED lamp bar.
Preferably, also be provided with some sites on the described end reflector plate.
Preferably, rounded, the square or diamond array in described some sites is on described reflector plate.
The utility model embodiment provides a kind of liquid crystal indicator, and it comprises the down straight aphototropism mode set described in above-mentioned arbitrary technical scheme.
Down straight aphototropism mode set disclosed in the utility model, by changing the position that arranges of LED lamp bar, soon LED lamp bar is arranged on the position apart from end reflector plate H distance, also be about to light mixing distance and increased the H distance, and then also reduced the thickness of this down straight aphototropism mode set, and improved this down straight aphototropism mode set and gone out uniformity of light, and achieving the above object does not need to increase the number of LED, so the utility model down straight aphototropism mode set has reached the purpose that increases light mixing distance on the basis that does not increase cost, make that the bright dipping of the utility model down straight aphototropism mode set is even, and realized lightening.
Description of drawings
Fig. 1 is the schematic diagram of down straight aphototropism mode set in the utility model preferred embodiment;
Fig. 2 becomes irregular schematic diagram of arranging for site in the utility model preferred embodiment;
Fig. 3 is arranged into square schematic diagram for site rule in the utility model preferred embodiment.
The realization of the utility model purpose, functional characteristics and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model provides a kind of down straight aphototropism mode set, with reference to shown in Figure 1, this down straight aphototropism mode set comprises module shell 1, reflector plate 3 and is installed with the LED lamp bar 2 of some LED4, and reflector plate 3 comprises the end reflector plate 31 on the base plate 11 that is fixedly arranged on module shell 1 and is fixedly arranged on lateral reflection sheet 32 on the side plate 12 of module shell 1.The side plate 12 of module shell 1 is provided with the mounting groove (not shown), LED lamp bar 2 is trapped in the mounting groove with fixing with module shell 1, and the distance that arranges between position and the end reflector plate 31 of LED lamp bar 2 is H, H be down straight aphototropism mode set thickness (height of module exiting surface backlight) 1/2 ~ 4/5, the thickness of general down straight aphototropism mode set is 20 ~ 50MM, in the present embodiment, H be down straight aphototropism mode set thickness 1/2.Some LED4 arrange towards end reflector plate 31, namely the light that sends of some LED4 towards end reflector plate 31 so that light source to be provided.
Being understandable that end reflector plate 31 and lateral reflection sheet 32 can be to be wholely set, also can be the split setting.
Be understandable that LED lamp bar 2 is not limited to be fixed on the side plate 12 of module shell 1, also can LED lamp bar 2 be fixed on the base plate 11 of module shell 1 by a fixture.Simultaneously, it is fixing that LED lamp bar 2 also is not limited to be trapped in the side plate 12 of mode in the mounting groove and module shell 1, can also LED lamp bar 2 be fixed on the side plate 12 of module shell 1 by the mode of screw thread or buckle.
Down straight aphototropism mode set disclosed in the utility model, by changing the position that arranges of LED lamp bar 2, soon LED lamp bar 2 is arranged on the position apart from end reflector plate 31H distance, also be about to light mixing distance and increased the H distance, and then also reduced the thickness of this down straight aphototropism mode set, and improved this down straight aphototropism mode set and gone out uniformity of light, and achieving the above object does not need to increase the number of LED, so the utility model down straight aphototropism mode set has reached the purpose that increases light mixing distance on the basis that does not increase cost, make that the bright dipping of the utility model down straight aphototropism mode set is even, and realized lightening.
Because the setting of LED lamp bar 2 has stopped the light that reflector plate 3 reflects, in order to remedy the blanking bar that LED lamp bar 2 causes, in a preferred embodiment, also be provided with some the 2nd LED5 back to end reflector plate 31 on the LED lamp bar 2, it is light that some the 2nd LED5 send is higher than the 2nd LED5 away from the lumen value of end reflector plate 31, the one LED4 lumen value.
Be understandable that, the 2nd LED5 can be arranged on the same LED lamp bar 2 with a LED4, but is not limited to this, as the conduct distortion, the 2nd LED5 and a LED4 can also be arranged on the different LED lamp bars 2, the 2nd LED5 arranges the position and only need remedy the blanking bar that LED lamp bar 2 causes and get final product.
In order to make the bright dipping of the utility model down straight aphototropism mode set even further, in a preferred embodiment, also be provided with some sites on the end reflector plate 31.The irregular alignment of some sites is on reflector plate 31, as shown in Figure 2; Some sites also can be regularly arranged on reflector plate 31, as rounded, square or diamond array on reflector plate 31.As shown in Figure 3, some sites are square and are arranged on the reflector plate 31.
