Description
Technical field
The present invention relates to a kind of gradient refractive index light-guiding lamp box, more particularly to a kind of gradient refractive index light-guiding lamp box.
Background technology
Currently, there are mainly three types of light-source structures for LED light box：The first, is placed on light guide plate side by LED, is then leading
Some sites or grid are designed on tabula rasa, LED light enters in light guide plate, is reflected after encountering site or grid, injection is led
Tabula rasa forms uniform area source；Second, LED side light sources are used in lamp box, and LED side light sources are designed in the side of lamp box
Wall changes the light emitting angle of LED, light is made more to front irradiation, to be formed equal by increasing secondary optical lens on LED
Even light；The third places plurality of rows of backlight, light is logical using backlight as the light source of lamp box in the bottom of lamp box
The birefringence for crossing backlight lens forms uniform light and is radiated on the picture of lamp box.
The shortcomings that the first above-mentioned light box with light plate is：LED is placed on light guide plate side, and the light of LED enters light guide plate
During, there is some light to be irradiated to outside light guide plate, with the increase of size, the uniformity of light guide plate entirety can decline；
And the shortcomings that second of side light source lamp box, is：It is higher to the thickness requirement of lamp box entirety due to being to use side light source light source, it cannot
Ultrathin lamp box is enough done, the problem of intermediate uniformity reduces also is will appear when size is larger；The third the shortcomings that is：Due to being
LED is placed on to the bottom of lamp box, more LED is needed to be arranged, whole power is very big, can discharge more heat
With use more electric energy.
In a kind of structure disclosed in existing technology, a side that light imports plate is bevel edge, and light imports plate and is tightly attached to diverging
The back side of plate, and its bevel edge is outwardly.LED light source is set to the bevel edge opposite side that light imports plate, and light is imported from the side, through bevel edge
It is totally reflected into diverging plate.Light imports between the plate side closer from LED light source and diverging plate and is provided with light shield layer, prevents LED light
Source anaclasis enters diverging plate, this technical solution solves the uniformity problems of large scale lamp box, but is put in guide-lighting back
The scheme of LED is set, a large amount of LED can be used, the power of lamp box can be very big, can not reach energy-efficient purpose, this scheme is in group
It is relatively complicated when dress, a large amount of human and material resources can be wasted.
In another structure disclosed in existing technology, light guide plate is set in frame, and side light source is set to guide-lighting edges of boards
Edge buries inside light-guide edge, and the light guide plate includes plate body and intersperses among the light guide on plate body；The light guide packet
Diamond shape cone bottom and the vertex of a cone are included, there is orthogonal first seamed edge of falling V and the second seamed edge of falling V, the first seamed edge of falling V directional light
Line incident direction, the vertical light incident direction of the second seamed edge of falling V, though such scheme can improve the uniformity of lamp box, LED
Light greatly do not enter into light guide plate, lamp box overall brightness is relatively low.
It is accordingly required in particular to which a kind of gradient refractive index light-guiding lamp box, above-mentioned existing to solve the problems, such as.
Invention content
The purpose of the present invention is to provide a kind of gradient refractive index light-guiding lamp boxes to meet LED light in view of the deficiencies of the prior art
The uniformity of the demand of case, lamp box is high, promotes overall brightness, will not discharge more heat and use more electric energy.
Following technical scheme may be used to realize in technical problem solved by the invention：
A kind of gradient refractive index light-guiding lamp box, which is characterized in that it includes light box, is provided at the back side of the light box
Several refraction panels are provided with the white refractile body arranged in gradient in the refraction panel member, the two of the refraction panel
Side is provided with LED light source.
In one embodiment of the invention, the white refractile body is that extrusion, printing, printing or mechanical processing are made.
In one embodiment of the invention, the white refractile body according to apart from LED light source by closely to remote, the white
The size of refractile body is from small to large.
In one embodiment of the invention, the white refractile body according to apart from LED light source by closely to remote, the white
The height of refractile body is from low to high.
In one embodiment of the invention, the white refractile body according to apart from LED light source by closely to remote, the white
The distance between refractile body is from large to small.
In one embodiment of the invention, the shape of the white refractile body includes but not limited to rectangle, triangle, ladder
Shape, taper and cylinder.
The gradient refractive index light-guiding lamp box of the present invention, compared with prior art, by the way that refraction panel is arranged in light box,
The white refractile body arranged in gradient is set on refraction panel, and the uniformity of lamp box is high, promotes the overall brightness of lamp box, and not
More heat can be discharged and use more electric energy, meet the needs of LED light box, achieve the object of the present invention.
