Abstract
The utility model discloses a direct type television reflector plate structure, which comprises a flake reflection body, the reflection body is provided with multiple rows of LEDs (light-emitting diode) as back light sources and assembly holes for the LED light sources to pass, and a strip arch with the triangular cross section is arranged in the middle of the reflection body. According to the direct type television reflector plate structure, a new reflector plate structure with the middle arch is adopted, and the height and span of the arch are determined according to the lighting angle and the height of the mixed light of the light sources on LED light bars. The direct type television reflector plate structure is used for compensating light rays in non-luminance areas among the light sources and improving the defect of poor uniformity of the whole television image of a low-power dissipation direct type television with less light sources and lower mixed light height.
Description
Technical field
The utility model relates to a kind of television set, particularly a kind of straight-down negative television set reflector plate structure.
Background technology
In existing straight-down negative television set, reflector plate is tiling, for obtain exiting surface to diffuser plate after projecting the light reflection of bottom, follow client's optics grade more and more higher, simultaneously country also puts into effect efficiency subsidy policy, and straight-down negative television set is in optics grade and meet between low-power consumption demand and occur contradiction.Have compared with the straight-down negative television set of low energy consumption owing to adopting light source particle less, when pure color picture, optics grade is poor.Because light source particle is less and the more and more lower light path that causes of mixed light height shortens, the not luminous distance between light source and light source can not be by even light well.Though and the large straight-down negative television set optics grade of light mixing distance is good, but can sacrifice complete machine thickness, client is generally willing to now mean thinner straight-down negative television set and checks.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides the less light source of a kind of improvement, the lower mixed light inhomogeneity not enough straight-down negative television set reflector plate structure of low-power consumption straight-down negative television set complete machine picture to heavens.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of straight-down negative television set reflector plate structure, comprise the reflection body of sheet, described reflection body is provided with the LED of some rows as backlight, and the pilot hole passing for LED light source, it is that leg-of-mutton strip arches upward that the centre of described reflection body is provided with a cross section.
As further improvement of the utility model, the mixed light height that the cross section vertical height H that described strip arches upward is 1/5-1/2.
As further improvement of the utility model, the top included angle A of the cross section that described strip arches upward is between 90 degree to 165 degree.
The beneficial effects of the utility model are: the utility model adopts new reflector plate structure, in the middle of it, arch upward, it determines according to the lighting angle of light source on LED lamp bar, mixed light height arch upward height and span, for the light of light-emitting zone not between compensatory light and light source, improve less light source, the lower mixed light inhomogeneity deficiency of low-power consumption straight-down negative television set complete machine picture to heavens; Indirectly increase the optical path length of lower light mixing distance, make the good blanking bar of diffuser plate light inlet side obtain more light, when meeting low-power consumption policy, improve compared with the optics grade of low energy consumption straight-down negative television set, make picture have good homogeneity and grade.
Accompanying drawing explanation
Fig. 1 is the utility model reflector plate structure schematic diagram;
Fig. 2 is A-A portion enlarged diagram in Fig. 1;
Fig. 3 is the concrete structure schematic diagram of Fig. 2.
In figure, indicate: 1-reflects body; 2-LED; 3-pilot hole; 4-strip arches upward.
The specific embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
Fig. 3 shows a kind of embodiment of a kind of straight-down negative television set of the utility model reflector plate structure, comprise the reflection body 1 of sheet, described reflection body is provided with the LED2 of some rows as backlight, and the pilot hole 3 passing for LED light source, it is that leg-of-mutton strip arches upward 4 that the centre of described reflection body 1 is provided with a cross section, the described strip mixed light height that 4 cross section vertical height H is 1/5-1/2 that arches upward, the arch upward top included angle A of 4 cross section of described strip is between 90 degree to 165 degree, can guarantee under two larger distances of light source, improve picture uniformity, improve picture taste, according to the lighting angle of light source on LED lamp bar, mixed light height determines arch upward height and span, for the light of light-emitting zone not between compensatory light and light source, make picture have good homogeneity and grade.
