Abstract
The utility model relates to a backlight module, and particularly relates to an energy-saving backlight module without a lamp shadow dark band. The energy-saving backlight module provided by the utility model comprises a reflector plate and at least two lamp tubes arranged on the reflector plate, wherein the reflector plate is provided with an arched arc-shaped bulge part which is arranged between the adjacent lamp tubes. The energy-saving backlight module provided by the utility model has the beneficial effects that the reflector plate is provided with the arc-shaped bulge part positioned between the adjacent lamp tubes, the arc-shaped bulge part can be used for achieving the light scattering effect, so that lamp shadow dark band can not form between the adjacent lamp tubes, and the lamp shadow dark band can not be generated under the premise that the number of lamp tubes is not increased; and the backlight module has the advantages of energy conservation and environment friendliness.
Description
Technical field
The utility model relates to backlight module, relates in particular to a kind of without lamp shadow blanking bar and energy-conservation backlight module.
Background technology
Backlight module is one of key part and component of panel of LCD.Function is well-off brightness and the light source that is evenly distributed, and makes normally show image of liquid crystal display.
To shown in Figure 2, be traditional backlight module such as Fig. 1, comprise reflector plate 1 and the fluorescent tube 2 that is arranged on the reflector plate 1, wherein, how the spacing of adjacent fluorescent tube 2 is larger, then forms easily the lamp shadow blanking bar between adjacent fluorescent tube 2, if overcome this lamp shadow blanking bar, then need with fluorescent tube 2 arrange quite intensive, so, although overcome the lamp shadow blanking bar, but cause fluorescent tube 2 quantity to rise, improve cost, also caused the rising of energy consumption, not environmental protection.
Therefore, how to design a kind of backlight module, can neither increase fluorescent tube quantity, not producing again the lamp shadow blanking bar is problem demanding prompt solution.
Summary of the invention
In order to solve the problems of the prior art, it is a kind of without lamp shadow blanking bar and energy-conservation backlight module that the utility model provides.
It is a kind of without lamp shadow blanking bar and energy-conservation backlight module that the utility model provides, comprise reflector plate and the fluorescent tube that is arranged on the described reflector plate, described fluorescent tube has two at least, and described reflector plate is provided with the arc convex section that arches upward, and described arc convex section is arranged between the adjacent described fluorescent tube.
As further improvement of the utility model, described arc convex section is semi-cylindrical hill section.
As further improvement of the utility model, the length of described arc convex section is more than or equal to the length of described fluorescent tube.
As further improvement of the utility model, described arc convex section parallels with described fluorescent tube.
As further improvement of the utility model, described arc convex section is strip.
As further improvement of the utility model, described arc convex section is arranged on the mid point of adjacent described fluorescent tube.
As further improvement of the utility model, described fluorescent tube is light-emitting diode lamp tube.
The beneficial effects of the utility model are: pass through such scheme, at reflector plate arc convex section is set, arc convex section is positioned between the adjacent fluorescent tube, can carry out light scattering by this arc convex section, to avoid between adjacent fluorescent tube, the forming lamp shadow blanking bar, can when not increasing fluorescent tube quantity, not produce the lamp shadow blanking bar, have the advantage of energy-saving and environmental protection.

The specific embodiment
Below in conjunction with description of drawings and the specific embodiment the utility model is further specified.
Drawing reference numeral among Fig. 3 to Fig. 4 is: reflector plate 1; Arc convex section 11; Fluorescent tube 2.
Extremely shown in Figure 4 such as Fig. 3, a kind of without lamp shadow blanking bar and energy-conservation backlight module, comprise reflector plate 1 and the fluorescent tube 2 that is arranged on the described reflector plate 1, described fluorescent tube 2 has two at least, described reflector plate 1 is provided with the arc convex section 11 that arches upward, and described arc convex section 11 is arranged between the adjacent described fluorescent tube 2.
To shown in Figure 4, described arc convex section 11 is semi-cylindrical hill section such as Fig. 3.
To shown in Figure 4, the length of described arc convex section 11 is more than or equal to the length of described fluorescent tube 2 such as Fig. 3.
To shown in Figure 4, described arc convex section 11 parallels with described fluorescent tube 2 such as Fig. 3.
To shown in Figure 4, described arc convex section 11 is strip such as Fig. 3.
To shown in Figure 4, described arc convex section 11 is arranged on the mid point of adjacent described fluorescent tube 2 such as Fig. 3.
To shown in Figure 4, described fluorescent tube is light-emitting diode lamp tube, i.e. the LED fluorescent tube such as Fig. 3.
What the utility model provided is a kind of without lamp shadow blanking bar and energy-conservation backlight module, at reflector plate 1 arc convex section 11 is set, make arc convex section 11 between adjacent fluorescent tube 2, can carry out light scattering by this arc convex section 11, to avoid between adjacent fluorescent tube 2, the forming lamp shadow blanking bar, can when not increasing fluorescent tube 2 quantity, not produce the lamp shadow blanking bar, have the advantage of energy-saving and environmental protection.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
