Abstract
This utility model relates to a kind of LED backlight, including LED light source and light guide plate；LED light source is launched light and is entered light guide plate from light guide plate side；Bottom surface of light guide plate is provided with reflector plate, and end face is provided with multiple V-type groove；Light guide plate is disposed as the inclined-plane tilted towards bottom surface of light guide plate away from other three sides of described LED light source, and inclined-plane outer surface is provided with light non-transmittable layers；Also include that the adapter sleeve between LED light source and light guide plate, adapter sleeve inwall are coated with reflecting coating；By arranging multiple V-type groove at light guide plate end face so that because angle causes the light that cannot penetrate angle when being mapped to V-type recess sidewall to change, improve the amount that can penetrate light, and then improve light utilization efficiency and back light source brightness；Overall structure is simple, low cost.
Description
Technical field
This utility model relates to back light source technique field, more particularly, it relates to a kind of LED backlight.
Background technology
In backlight source module, core technology is the optical technology of light guide plate, and the light that light source sends runs into after entering light guide plate leads
Tabula rasa inscattering luminous point generation diffuse-reflectance, the light bottom directive light guide plate is penetrated by light guide plate by baffle reflection, it is achieved
Backlight effect；But light is after running into scattering luminous point generation diffuse-reflectance, some light can be on light guide plate due to angle reason
Surface occurs total reflection cannot penetrate light guide plate, and light utilization efficiency is low.
Utility model content
The technical problems to be solved in the utility model is, for the drawbacks described above of prior art, it is provided that one can improve
The LED backlight of light utilization efficiency.
This utility model solves its technical problem and be the technical scheme is that
A kind of LED backlight of structure, including LED light source and light guide plate；It is characterized in that, described LED light source launches light
Described light guide plate is entered from described light guide plate side；Described bottom surface of light guide plate is provided with reflector plate, and it is recessed that end face is provided with multiple V-type
Groove；Described light guide plate is disposed as the inclined-plane tilted towards described bottom surface of light guide plate, institute away from other three sides of described LED light source
State inclined-plane outer surface and be provided with light non-transmittable layers；Also include the adapter sleeve between described LED light source and described light guide plate, described
Adapter sleeve inwall is coated with reflecting coating.
LED backlight described in the utility model, wherein, described light non-transmittable layers is aluminium lamination.
LED backlight described in the utility model, wherein, described inclined-plane is 5-towards described bottom surface of light guide plate angle of inclination
15 degree.
LED backlight described in the utility model, wherein, it is convex that described adapter sleeve inside upper surface is provided with multiple corrugated
Play type structure.
LED backlight described in the utility model, wherein, described V-type groove V-type A/F is 0.1-1mm.
LED backlight described in the utility model, wherein, described V-type groove V-type drift angle scope is 30-150 degree.
The beneficial effects of the utility model are: by arranging multiple V-type groove at light guide plate end face so that because angle is led
The light that cause cannot be penetrated angle when being mapped to V-type recess sidewall changes, and improves the amount that can penetrate light, and then improves light utilization
Rate and back light source brightness；Overall structure is simple, low cost.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below in conjunction with accompanying drawing
And embodiment the utility model is described in further detail, below describe in accompanying drawing be only part of the present utility model implement
Example, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtains according to these accompanying drawings
Other accompanying drawings:
Fig. 1 is the LED backlight structural representation of this utility model preferred embodiment；
Fig. 2 is the LED backlight V-type groove structure for amplifying schematic diagram of this utility model preferred embodiment.
Detailed description of the invention
In order to make the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with this practicality
Technical scheme in new embodiment carries out clear, complete description, it is clear that described embodiment is portion of the present utility model
Divide embodiment rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skill in the art are not paying
The every other embodiment obtained on the premise of creative work, broadly falls into protection domain of the present utility model.
The LED backlight of this utility model preferred embodiment is as it is shown in figure 1, simultaneously refering to Fig. 2, including LED light source 1 with lead
Tabula rasa 2；LED light source 1 is launched light and is entered light guide plate 2 from light guide plate 2 side；Light guide plate 2 bottom surface is provided with reflector plate 3, end face
It is provided with multiple V-type groove 20；By arranging multiple V-type groove 20 at light guide plate 2 end face so that because angle causes penetrating
Light angle when being mapped to V-type groove 20 sidewall change, improve the amount of light of can penetrating, and then improve light utilization efficiency and the back of the body
Light-source brightness；Overall structure is simple, low cost.
As it is shown in figure 1, light guide plate 2 is disposed as towards light guide plate 2 inclined bottom surface away from other three sides of LED light source 1
Inclined-plane 21, inclined-plane 21 outer surface surface configuration has light non-transmittable layers 210；Prevent from leading by arranging inclined-plane 21 and light non-transmittable layers 210
Tabula rasa 2 edge light leak.
As it is shown in figure 1, light non-transmittable layers 210 is aluminium lamination, it is mapped to the light at light guide plate 2 edge, improves light utilization efficiency and system
Making cheap, cost is relatively low.
As it is shown in figure 1, inclined-plane 21 is 5-15 degree towards light guide plate 2 inclined bottom surface angle.
As it is shown in figure 1, the adapter sleeve 4 also included between LED light source 1 and light guide plate 2, adapter sleeve 4 inwall is coated with
Reflecting coating, lower-cost raising LED light source injection light utilization efficiency.
As it is shown in figure 1, adapter sleeve 4 inside upper surface is provided with multiple corrugated lobe type construction 40, increases and inject optic angle
Degree, and then reduce the amount that can not penetrate light on light guide plate 2, improve light utilization efficiency.
As it is shown in figure 1, V-type groove 20V type A/F is 0.1-1mm.
As it is shown in figure 1, V-type groove 20V type drift angle scope is 30-150 degree.
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted,
And all these modifications and variations all should belong to the protection domain of this utility model claims.
