The present invention proposes a kind of down straight aphototropism mode set.
Fig. 4 is refer to, in an embodiment of the present invention, the down straight aphototropism mode set includes backboard 1, reflector plate 2, diffuser plate
3rd, some light sources 6 and the lens 5 covered above light source 6, backboard 1 include bottom plate 11 and the side plate 12 set around bottom plate 11,
The first cavity 13 is formed between bottom plate 11 and side plate 12, the first cavity 13 is encapsulated by diffuser plate 3, and reflector plate 2 is layed in bottom plate 11
On side plate 12, light source 6 and lens 5 are in the first cavity 13 and are arranged on side plate 12 and (and are specifically arranged at side plate 12
On reflector plate 2), lens 5 include site portion 52 and the smooth department 53 being oppositely arranged with site portion 52, and smooth department 53 is close to bottom plate
11.The light that site portion 52 launches light source 6 has very strong interception function and the light back of interception can go back.This
In embodiment, light source 6 corresponds with lens 5.
During down straight aphototropism mode set normal work, light source 6 launches light R1, and light R1 a part of light R11 is projected to
Site portion 52, another part light R12 are projected to smooth department 53.Light R11 is after site portion 52 reflects or reflected along different
Path is projected back to again to be come, and is projected back to the light come again after the reflector plate on side plate projects again, sub-fraction is again heavy
It is new to be projected to site portion 52, and most directive smooth departments 53, so move in circles so that most luminous energy in light source 6
Direct or indirect is projected to smooth department 53, and the light almost all for being projected to smooth department 53 is refracted in the first cavity 13.Thoroughly
Mirror 5 is covered on light source 6, and lens 5 and light source 6 are arranged on side plate 12, to same light source 6 and corresponding lens 5
For, reflector plate 2 of the site portion 52 away from bottom plate upward, smooth department 53 close to bottom plate reflector plate 2 down, this structure causes light
The preferential directive of luminous energy that source 6 is launched after lens 5 is located at the reflector plate 2 on bottom plate 11, then is arrived after the diffusing reflection of reflector plate 2
Up to diffuser plate 3 so that light mixing distance of the light in the first cavity 13 is greatly increased, and the luminous energy of each light source 6 is sufficiently mixed, finally
Uniform Energy distribution is formed on diffuser plate 3, avoids regional hot spot, so as to be realized on the premise of cost is not increased
Ultra-thin down straight aphototropism mode set.

Appropriate gap between second cavity 54 be present, the optical energy charging that this gap is advantageous to light source 6 disperses to penetrate or reflect.
Further, refer to Fig. 4 and Fig. 5, site portion 52 include close to the second cavity 54 the first dot surface 521 and with
Equal projection is some on the second dot surface 522 that first dot surface 521 is oppositely arranged, the first dot surface 521 and the second dot surface 522
Site projection 55, each site projection 55 is towards the second cavity 54.This site 55 pairs of light of projection have very strong scattering process,
Most luminous energy are eventually emitted from the smooth domain of lens 5.Preferably, raised 55 hemispherical, the first dot surfaces in site
521 and second dot surface 522 be arc surface, can increase light reflection or refraction path, so as to increase light mixing distance, make
The luminous energy for obtaining light source 6 is sufficiently mixed.
Preferably, lens 5 are rotary structure, and smoothly transit connection between site portion 52 and smooth department 53, and this structure makes
The light for obtaining light source 6 can be in an orderly manner along certain path conduct.Preferably, site portion 52 and smooth department 53 are right relative to light source 6
Claim to set so that the light of light source 6 is advanced along certain path more in an orderly manner, and the lens 5 of this structure are also easy to add
Work.
It refer to Fig. 6, light source 6 is the LED being arranged on pcb board, and the reflector plate on side plate is covered on pcb board, LED
Lamp is fixedly installed on pcb board through the reflector plate on side plate, lens 5 by several lens fixed feets 56, each light source 6
A corresponding lens 5, some arranged for interval of light source 6 form lamp bar.Pcb board is circuit board, is electrically connected with LED.The present embodiment
In, the graphite paint for being used for strengthening reflection function is coated with reflector plate 2.The light part that light source 6 is launched is by site portion 52
Or smooth department 53 reflects, and is reflected away again after being projected on reflector plate, and so on so that most in light source 6
Luminous energy it is direct or indirect be projected to smooth department 53, scattered through smooth department 53 to the first cavity 13.
In the present embodiment, side plate 12 be obliquely installed formed between the side of bottom plate 11, bottom plate 11 and side plate 12 it is trapezoidal
First cavity 13.Biside plate 12 is symmetrical arranged relative to bottom plate 11, and light source 6 and lens 5 corresponding with light source 6 are respectively arranged in side
On plate 12, the luminous energy of each light source 6 is further sufficiently mixed, avoid regional hot spot, finally formed on diffuser plate 3 uniform
Energy distribution, ultra-thin down straight aphototropism mode set is realized on the premise of cost is not increased.
In addition, being equipped with blooming piece on diffuser plate 3, some support columns are set between the reflector plate 2 of diffuser plate 3 and bottom plate
7, for being supported to diffuser plate 3, to prevent diffuser plate 3 from deforming.Wherein, blooming piece includes the upper diffusion set gradually
Piece, 0 ° of brightening piece, 90 ° of brightening pieces and lower diffusion sheet, under certain light source output, it will improved by blooming piece aobvious
The positive brightness or axial brightness of showing device.
The present invention also proposes a kind of display device, and the display device sets backlight module as described above.The display fills
