Description
Technical field
The utility model relates to a kind of gradient refractive index light-guiding lamp box, in particular to a kind of gradient refractive index light-guiding lamp box.
Background technique
Currently, there are mainly three types of light-source structures for LED light box: the first, LED is placed on light guide plate side, is then being led
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 source is used in lamp box, and LED side light source is designed in the side of lamp box
Wall changes the light emitting angle of LED, forms light more to front irradiation, equal by increasing secondary optical lens on LED
Even light；The third, uses backlight as the light source of lamp box, places plurality of rows of backlight in the bottom of lamp box, light is logical
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: due to be using side light source light source, it is higher to the thickness requirement of lamp box entirety, cannot
Ultrathin lamp box is enough done, also will appear the problem of intermediate uniformity reduces 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 plate and is provided with light shield layer between the closer side of LED light source and diverging plate, prevents LED light
Source anaclasis enters diverging plate, this technical solution solves the uniformity problems of large scale lamp box, but puts in guide-lighting back
The scheme for setting LED will use a large amount of LED, and 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 kind 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 lower.
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.
Summary of the invention
