Specific embodiment
In order to facilitate the understanding of those skilled in the art, below in conjunction with attached drawing and embodiment to the utility model carry out into
One step detailed description.
Embodiment one
Refering to fig. 1 ~ 5, a kind of backlight module with double luminous zones, including the guide-lighting film 2, second of shell 1, first are guide-lighting
Film 3, opaque diaphragm 4, the first side entering type lamp bar 5 and the second side entering type lamp bar 6, shell 1 are guide-lighting film, side entering type lamp bar
Installation and support construction, be traditionally arranged to be upper opening, there are side wall, lower part structure with the end in four sides.Described first guide-lighting glue
Piece 2 and the second guide-lighting film 3 are disposed in parallel in shell 1, are passed through between the described first guide-lighting film 2 and the second guide-lighting film 3
Opaque diaphragm 4 separates, so that the first guide-lighting film 2 and the second 3 region of guide-lighting film are respectively formed an independence
Luminous zone, do not generate each other light mixing interference.First side entering type lamp bar 5 is set on the outside of the first guide-lighting film 2, described second
Second side entering type lamp bar 6 is set on the outside of guide-lighting film 3, and respectively two independent luminous zones provide light source.
Light source Unequal distance arrangement in the first side entering type lamp bar 5 and/or the second side entering type lamp bar 6, so that hair
Two in light area or any one form a kind of special illumination effect.Such as it is light source is successively gradually thinning from centre toward both sides
Arrangement forms the gradually dimmed illumination effect of bright both sides among luminous zone；It may be arranged as bright wisp and filaments of sun interleaved point
The effect of cloth specifically can according to need setting.
Refering to fig. 1 and Fig. 4, two sides adjacent outside the described first guide-lighting film 2 and/or the second guide-lighting film 3 are provided with
Adjacent two sides lamp bar can be all made of light source unequal spacing above-mentioned setting by side entering type lamp bar, can also will wherein side
Light source spaced set, other side unequal spacing setting, to realize the special light efficiency display effect of richer mould group.It can be with
By the color of light source luminescent in the side entering type lamp bar of two sides adjacent outside the described first guide-lighting film 2 and/or the second guide-lighting film 3
It is set as different, forms new color after the light light mixing of two sides different colours, further enrich the special light efficiency display effect of mould group.
A kind of specific set-up mode is shown in Fig. 1 and Fig. 4, two lamp bars are arranged in adjacent two sides outside the second guide-lighting film 3,
In two side entering type lamp bars, a light source 62 is arranged in the side entering type lamp bar of side, emits white light；Light source in another side entering type lamp bar
Amber light is sent out to dilute light source 61 being arranged successively by close since side, the effect of realization is to lean at close to sources 62 in mould group
Brightness is higher, and color, closer to white, as position is far from light source 61, mould group light emission luminance is lower, and color moves closer to
It is amber.One the first side entering type lamp bar 5 is only set on the outside of first leaded light film 2, and corresponds to and is opened up often in the first guide-lighting film 2
The receiving position 22 of a light source 51, so that the light that the light source 51 in the first guide-lighting 2 outside of film issues more enters the first leaded light
In film 2, the utilization rate that shines is improved.
Refering to Fig. 5, in order to facilitate the production and installation of lamp bar, the first side entering type lamp bar 5 and the second side entering type lamp bar 6
Preferably with the mode being arranged in same lamp bar, i.e. the first side entering type lamp bar 5 and the second side entering type lamp bar 6 are respectively same
The luminous section of difference in lamp bar, each section independence power control.Such as in Fig. 5,61 place section of light source 62 and light source
Respectively as two the second side entering type lamp bars 6 outside the second guide-lighting film 3,51 place section of light source is as the first side entering type lamp bar
5.Lamp bar, can be according to the shape needs of the first guide-lighting film 2 and the second guide-lighting film 3 in such a way that LED is welded and fixed in FPC
Bending, and be bonded in shell 1 by heat-conducting glue.
Refering to fig. 1, opaque diaphragm 4 can reflect light back into leaded light by reflective aluminium film preferably with reflective aluminium film
Recycling, improves the utilization rate of light, also improves the light efficiency of mould group in film.
Refering to Fig. 2 and Fig. 3, the described first guide-lighting film 2 and the second guide-lighting film 3 are clamped by the buckle structure in outside
On shell 1, can on the outside of the first guide-lighting film 2 the wedge-shaped chuck 21 of setting first, the is arranged on the outside of the second guide-lighting film 3
Two wedge-shaped chuck 31 can make first to lead in 1 corresponding position of shell setting bayonet 11 by wedge-shaped chuck and bayonet arrangement
Ray film 2 and the second guide-lighting 3 outside of film are pushed against with 1 inner wall of shell, and the first guide-lighting film 2 and the second guide-lighting film 3 is avoided to exist
It is shaken in shell 1.Wedge-shaped chuck is easy for installation, and from top to bottom putting down guide-lighting film can be by guide-lighting film clamping.
It refering to fig. 1, further include reflective membrane 7 and light-diffusing film 8, the first guide-lighting film 2 and second is being stated in the setting of reflective membrane 7
Guide-lighting film 3 is in the following, the light-diffusing film 8 is arranged on the first guide-lighting film 2 and the second guide-lighting film 3.If 1 inner wall of shell
For white, reflective membrane 7 can also be not provided with.It is covered with shading glue 9 on the side of side entering type lamp bar on the light-diffusing film 8,
To cover the speck generated above side entering type lamp bar.The light-diffusing film 8 is bonded on shell 1 by double-sided adhesive 10, thus lower glue
Light-diffusing film 8 and the first guide-lighting film 2 and the second guide-lighting film 3 are each attached in shell 1 by face, and upper glue surface can be subsequent solid
Determine the structures such as liquid crystal module.
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
Exhaustion.Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc., should be included in
Within the protection scope of the utility model claims.
