The utility model proposes a kind of backlight module.
Referring to figs. 1 through the structural representation that 5, Fig. 1 is the utility model backlight module one embodiment; The lamp guide of Fig. 2 for the backlight module shown in Fig. 1 and the connection diagram of optical fiber; Fig. 3 is the part-structure cut-open view of an embodiment of light collecting device of the present utility model; Fig. 4 be lamp guide and the fiber coupler of the utility model backlight module coordinate schematic diagram; Fig. 5 be the utility model backlight module lamp guide with another embodiment of fiber coupler coordinate schematic diagram.
In the utility model embodiment, as shown in Figures 1 to 3, the utility model provides a kind of backlight module 100, backlight module 100 comprises light guide plate 1 and is located at the lamp guide 2 of a side of light guide plate 1, the side exiting surface 21 that lamp guide 2 has the light inputting end 2a in order to be connected with the optical fiber 201 of light collecting device 200 and is oppositely arranged with a side surface of light guide plate 1, light inputting end 2a in order to the light in optical fiber 201 is introduced in lamp guide 2, side exiting surface 21 for by the light refraction in lamp guide 2 in light guide plate 1.
Concrete, sunshine is collected by light collecting device 200, (material of lamp guide 2 can adopt the material that light guide plate 1 is identical again sunshine to be conducted to lamp guide 2 by optical fiber 201, general employing optical grade acrylic (PMMA)/PC is base material) in, lamp guide 2 by side exiting surface 21 by light reflection in light guide plate 1.So, light can be provided to light guide plate 1 by the setting of light collecting device 200 and lamp guide 2, save electric power and the energy, reduce the energy consumption of backlight module 100, make the energy-conserving and environment-protective more of display and display system.
In the present embodiment, with reference to Fig. 4 and Fig. 5, the bright dipping side 21 towards light guide plate 1 of lamp guide 2 has the bright dipping region 21a that the length direction along lamp guide 2 extends, and is provided with multiple light guiding points 22 in the 21a of bright dipping region, for guiding light refraction in lamp guide 2 in light guide plate 1.So, light is when transferring to lamp guide 2 by optical fiber 201, and in order to the utilization factor of the propagation efficiency and light that strengthen light, the incident angle that generally can adjust light is totally reflected in lamp guide 2 to make light.The setting of light guiding points 22 is in order to when light transmition is to lamp guide 2 side exiting surface 21, destroys total reflection, light is penetrated from lamp guide 2, for light guide plate 1 provides light source.Should be understood that, arranging of this light guiding points 22 can adopt laser printing technology, also can adopt printing technology, all in protection domain of the present utility model.
In the present embodiment, can be: bright dipping region 21a is wide setting that the multiple light guiding points 22 away from light inputting end 2a are gradually close setting with reference to Fig. 5, bright dipping region 21a and arranging of light guiding points 22.Light conduction in lamp guide 2 can cause the decay of the light of a part, brightness near light inputting end 2a is high, on the direction away from light inputting end 2a, the brightness step-down gradually of light, therefore becomes in the density of the light guiding points 22 that this side up is arranged and penetrates in making more light by lamp guide 2 greatly.
Certainly, with reference to Fig. 4, based on same principle, bright dipping region 21a and light guiding points 22 can also be arranged to: bright dipping region 21a is in gradually wide setting, and the multiple light guiding points 22 away from light inputting end 2a are arranged in even.
In the present embodiment, with reference to Fig. 4 and 5, the light inputting end 2a of lamp guide 2 is provided with fiber coupler 4, lamp guide 2 is connected with optical fiber 201 by fiber coupler 4, fiber coupler 4, for controlling the incident angle be incident to by the light in optical fiber 201 in lamp guide 2, is totally reflected in lamp guide 2 to make the light in lamp guide 2.So, fiber coupler 4 be arranged so that optical fiber 201 conducts the light of coming and enters in lamp guide 2 efficiently, simultaneously can control direction and the incident angle that light injects lamp guide 2, ensureing that most of light enters lamp guide 2 is meet total reflection condition.So, the utilization ratio of light can be strengthened.
In the present embodiment, with reference to Fig. 1, backlight module 100 also comprises taking the shape of the letter U and arranges reflecting plate 5, and lamp guide 2 is built in reflecting plate 5, the opening of reflecting plate 5 is arranged towards light guide plate 1, for by lamp guide 2 by deviate from light guide plate 1 surface penetrate light reflection to light guide plate 1.So, the setting of reflecting plate 5 can strengthen the utilization ratio of light, and the light of lamp guide 2 can be fully used.The light of multiple surfaces injection of lamp guide 2 all can be reflexed in light guide plate 1 by reflex housing 5, strengthens the utilization ratio of light further.Should be understood that, reflecting plate 5 can be fitted with lamp guide 2, and the side exiting surface 2a of lamp guide 2 can fit light guide plate 1 or leave fine pitch, and position so is arranged also at protection domain of the present utility model.
In the present embodiment, with reference to Fig. 2, backlight module 100 also comprises lamp bar 3, lamp bar 3 both sides of being located at light guide plate 1 relative to lamp guide 2.So, when outside sunray is darker, lamp bar 3 can be enabled to provide light to light guide plate 1.
The utility model also proposes a kind of display (not shown), comprise backlight module 100, the concrete structure of this backlight module 100 is with reference to above-described embodiment, because this display have employed whole technical schemes of above-mentioned all embodiments, therefore all beneficial effects that the technical scheme having above-described embodiment is equally brought, this is no longer going to repeat them.
In the present embodiment, with reference to Fig. 1, the brightness detector (not shown) that display comprises controller (not shown) and is electrically connected with controller, backlight module 100 also comprises the lamp bar 3 (being preferably LED lamp bar 3) be electrically connected with controller, lamp bar 3 and lamp guide 2 are located at the relative dual-side of light guide plate 1, controller is used for after the brightness of the light guide plate detected receiving brightness detector, the brightness of regulation and control lamp bar 3.
Because the limited resource of sunshine resource is more, such as, cloudy day, rainy day, night, enough sunrays can not be provided, so the dependence sunray that this novel backlight module 100 is not single, also retains lamp bar 3 at a side of light guide plate 1.When brightness detector detects that the brightness of light guide plate 1 is inadequate, controller can control lamp bar 3 and open, and is supplemented by the light source of lamp bar 3, utilize the mode that this hybrid light source throws light on, under the prerequisite ensureing normal use viewing, utilize solar energy resources, saved the energy.
The utility model also proposes a kind of display system (not shown), comprise light collecting device 200 and display, the concrete structure of this display is with reference to above-described embodiment, because this display system have employed whole technical schemes of above-mentioned all embodiments, therefore all beneficial effects that the technical scheme having above-described embodiment is equally brought, this is no longer going to repeat them.Wherein, the end face of one end away from lamp guide 2 of optical fiber 201 is provided with anti-reflection film (not shown).Also namely to the end face coating process of optical fiber 201, the utilization ratio of optical fiber 201 pairs of luminous energy can so be strengthened.
Should be noted that; the technical scheme of each embodiment of the present utility model can be combined with each other; but must be can be embodied as basis with those skilled in the art; when technical scheme combination occur conflicting maybe cannot realize time will be understood that the combination of this technical scheme does not exist, also not the utility model require protection domain within.
