A kind of liquid crystal display light supply apparatus of vehicle-mounted head-up display system, it is characterised in that including：Display screen, diffusion barrier, thoroughly
Mirror structure, light source, fin and box body, the diffusion barrier are located between display screen and lens arrangement, the lens arrangement and light
In box body, the end of the lens arrangement is connected with light source in source, and the fin is located at the end of box body, the fin
Touched with light source.
Further, the lens arrangement includes：Supplementary lens and concavees lens, the supplementary lens are Fresnel Lenses, institute
The front end for stating supplementary lens and box body connects, and the concavees lens are located at the front end of light source.
Further, the box body is approximate square funnel structure, and box body four sides inwall is provided with minute surface.
Further, the display screen is TFT display screens.
Further, the light source is LED array light source.
The beneficial effects of the utility model：
The utility model will be diffused into larger area compared with conventional art, using concavees lens compared with small area LED light source, have
Effect improves light source utilization rate；The incident light of various angles at random is adjusted to parallel afterwards through refraction using Fresnel Lenses
Light, TFT liquid crystal displays are made to obtain optimal angle of incidence of light degree；LED light source area is less than the area of LCDs.Less light
Source area can effectively control the problems such as heating；Inwall uses specular material, and light can be made to form mirror-reflection, effectively improved
Source efficiency.

Embodiment
Below in conjunction with specific embodiment, make progressive explanation to the utility model.It should be understood that following examples are merely to illustrate
The utility model is not for restriction the scope of the utility model.
Embodiment 1
Fig. 1 is structure chart of the present utility model.Fig. 2 schematic diagrams of the present utility model.Fig. 3 ties for perspective of the present utility model
Composition.
As shown in figure 1, a kind of liquid crystal display light supply apparatus of vehicle-mounted head-up display system includes：Display screen 100, diffusion barrier
200th, lens arrangement 300, light source 400, fin 500 and box body 600, diffusion barrier 200 are located at display screen 100 and lens arrangement
Between 300, in box body 600, the end of lens arrangement 300 is connected with light source 400 for lens arrangement 300 and light source 400, radiating
Piece 500 is located at the end of box body 600, and fin 500 touches with light source 400.
Lens arrangement 300 includes：Supplementary lens 310 and concavees lens 320, supplementary lens 310 is Fresnel Lenses, preposition
Mirror 310 is connected with the front end of box body 600, and concavees lens 320 are located at the front end of light source 400.
Box body 600 is approximate square funnel structure, and the four sides inwall of box body 600 is provided with minute surface 610.
Display screen 100 is TFT display screens.
Light source 400 is LED array light source.
Following defect be present in the technical scheme of the liquid crystal display light supply apparatus of existing vehicle-mounted head-up display system：Light-source brightness
Deficiency, the LCDs of vehicle-mounted head-up display system need to remain able to display clearly image in the case of sunlight
Word, so the light source of LCDs needs higher brightness.LCDs brightness based on prior art is about
1.8 cun of liquid crystal displays of only 400 lumen, in the case of sunny, the pictograph content that liquid crystal display can be caused to show is fuzzy not
Clearly.
Liquid crystal display display brightness is uneven, and the liquid crystal display of prior art has core brightness higher than marginal portion
Phenomenon, it is due to that the light sent from light source does not pass through effective diffusion and carries out dodging.
As shown in Figures 2 and 3, principle of the present utility model is luminous, LED array after the energization source of LED array light source 400
Light source 400 is radiated by bottom of device fin 500, prevents high temperature from causing light source to damage.It is recessed on fin 500
Mirror 320, light is expanded to the TFT display screens 100 of larger area from less LED array light-emitting area.By concavees lens 320
Refraction, and edge minute surface 610 reflect light reach top Fresnel supplementary lens 310, it is ensured that light source maximum profit
With rate.Incident ray refraction is transformed to the directional light perpendicular to minute surface by Fresnel supplementary lens 310 afterwards, then passes through diffusion
Film 200 makes light be evenly distributed.Enter TFT display screens 100 after diffusion barrier 200, turn into the light source of display image word.
The utility model will be diffused into larger area compared with conventional art, using concavees lens compared with small area LED light source, have
Effect improves light source utilization rate；Use the adjustment after refraction by the incident light of various angles at random of Fresnel supplementary lens 310
For directional light, TFT liquid crystal displays 100 are made to obtain optimal angle of incidence of light degree；LED light source area is less than the face of TFT liquid crystal displays 100
Product.Less light source area can effectively control the problems such as heating；Inwall uses the material of minute surface 610, and light can be made to form mirror
Face is reflected, and effectively improves source efficiency.
Specific embodiment of the present utility model is illustrated above, but the utility model is not limited thereto, only
Objective of the present utility model is not departed from, the utility model there can also be various change.
