Compared with the existing technology, it the utility model has the beneficial effects that: the utility model uses two LED light bars, mentions
High LED amount of luminescence, to improve brightness, and two LED light bars are set to light guide plate the same side, so still it is unilateral into
Light does not increase additional difficulty so that the optical effect of light guide plate is handled with general light guide plate；And light conducting plate structure is set
Meter, it is limited to increase light-emitting area, and then improve the light emission luminance of unit area；And the zigzag concave arc of optical diaphragm
The light that face energy comprehensive collection light guide plate is emitted, then exported from light-emitting surface, realize high brightness, high uniformity output.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of LED backlight mould group of high brightness of the utility model.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment one
Refering to Figure 1, the present embodiment provides a kind of LED backlight mould group of high brightness, including backboard 1, it is set to backboard 1
On LED backlight 2, in LED backlight 2 and light guide plate 3 that corresponding LED backlight 2 is arranged, be set to LED backlight 2 with
Reflector plate 4 between backboard 1 and the optical diaphragm on light guide plate 35, LED backlight 2 include a flexible circuit board 21 and
Two are welded in the LED light bar 22 on flexible circuit board 21 in parallel, and the length of illumination of LED light bar 22 is equal to the length of light guide plate 3,
The upper surface of light guide plate 3 is the zigzag arcwall face to raise upward, and the width of zigzag arcwall face is greater than LED backlight 2
The two sides of width, light guide plate extend obliquely upward, and the upper surface that the incidence surface of optical diaphragm 5 corresponds to light guide plate 3 is in zigzag
Concave arc surface 51, the light-emitting surface of optical diaphragm 5 are planar light-emitting surface 52.
Preferably, LED backlight 2 against the setting of light guide plate 3, is avoided, there is a situation where light leakages.
The light guide plate 3 is process using acrylic board.
The flexible circuit board 21 is equipped with single line and two pads, and two pads are single for welding two LED light bars 22
Route is connect with two pads, to provide working power to LED light bar 22.21 structure of flexible circuit board is simple, easy to process,
While advantageously reducing production cost, production efficiency is improved.
The present embodiment improves LED amount of luminescence, to improve brightness, and two because using two LED light bars 22
LED light bar 22 is set to 3 the same side of light guide plate, so still unilateral entering light, so that the optical effect of light guide plate 3 is handled with general
Light guide plate, do not increase additional difficulty.
The structure of the present embodiment light guide plate 3 designs, limited to increase light-emitting area, and then improves shining for unit area
