Abstract
The utility model discloses a leaded light formula back of body light structures, including gluing frame, LED lamp, set up light guide plate and leaded light strip on gluing the frame, the leaded light strip is used for turning into the area source with the pointolite of LED lamp, smooth incline looks adaptation is gone into by a long and high side that constitutes with the light guide plate by the wide and high side that constitutes, leaded light strip at the leaded light strip to the setting of LED lamp, and the other side of light guide plate is provided with the offside reflection membrane, the bottom surface of light guide plate is provided with the reflectance coating, and the up end is provided with astigmatic membrane, still be provided with the PCB board on gluing the frame, LED lamp device is on the PCB board. The utility model discloses can effectively solve LED quantity when less, the light guide plate advances phenomenons such as lamp eye that the light mode easily caused, dark space, dark group with traditional pointolite, simultaneously also can the phenomenons such as lamp eye of effectual solution because of effectively leading the less appearance of light zone.
Description
Technical field
The utility model is related to a kind of light-guiding type back light source structure.
Background technology
With the development in backlight market, not only client is to the quality requirements more and more higher of backlight, and competes day increasingly
Acute market, client requires also more and more higher to the cost cost performance of backlight.Pressure or product of the terminal client under the pressure of cost
Product actual operation requirements are not high, may require that backlight supplier and backlight is made using few LED, backlight LED quantity
Less light guide plate illumination effect will be difficult treatment；Or due to the limitation of backlight source module structure, effectively guide-lighting distance is very
Small, guide-lighting using traditional side entering type, because the thickness of LED can cause valid trace electrical distance smaller, it is that spot light has to add LED
Lighting angle, light guide plate illumination effect just occurs headlight phenomenon, the lamp eye that we often say, also occurs between LED secretly
There is dark group in area, light-emitting zone, and LED exit positions occur intersecting eight words etc..Client cannot thus be met to backlight source module
The requirement of display；Effect process bad client will not receive, or require that client increases LED, can thus increase cost, lose
The market competitiveness.
Utility model content
The purpose of this utility model is to provide a kind of light-guiding type back light source structure, when solving LED negligible amounts, light guide plate with
The phenomenons such as lamp eye, dark space, dark group that traditional spot light entering light mode is easily caused, while can also effectively solve because effectively guide-lighting
The phenomenons such as the lamp eye of the smaller appearance in area.
The utility model solves the technical scheme that its technical problem used：A kind of light-guiding type back light source structure, including
Glue frame, LED, are arranged on light guide plate and light-strip in glue frame, and light-strip is used to for the spot light of LED to be converted into face light
Source；LED is arranged on light-strip by the side for constituting wide and high, and light-strip is entered by growing with the side for constituting high and light guide plate
Light side is adapted, and the other side of light guide plate is provided with offside reflection film；The bottom surface of light guide plate is provided with reflectance coating, and upper surface sets
It is equipped with light-diffusing film；Pcb board is additionally provided with glue frame, LED lamp device is on pcb board.
In order to improve reasonable structure, glue frame includes being arranged on the fixed frame of light guide plate corner and for fixing light-strip
The L-shaped coating in section, pcb board is arranged in coating, and light-strip is fixed on pcb board away from the side of light guide plate.
Preferably, light-strip is respectively arranged with a LED by two sides for constituting wide and high.
In order that must simplify the structure, the incident side of light guide plate sets one.
Preferably, light guide plate and light-strip are all rectangle.
The beneficial effects of the utility model：Light-strip converts for area source the spot light of LED, then with area source
Mode is imported light into inside light guide plate, and the illumination effect of customer demand can be thus completed with a small amount of LED, is solved
During LED negligible amounts, the phenomenon such as lamp eye, dark space, dark group that light guide plate is easily caused in traditional spot light entering light mode, while also may be used
With the effective phenomenon such as lamp eye solved because of the smaller appearance in effective light guide zone.
Below with reference to drawings and Examples, the utility model is described in detail.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.

Other side is provided with offside reflection film 6；The bottom surface of light guide plate 7 is provided with reflectance coating 5, and upper surface is provided with light-diffusing film 8；Glue
Pcb board 2 is additionally provided with frame, the device of LED 3 is on pcb board 2.
Glue frame includes being arranged on the fixed frame 9 and the coating L-shaped for fixing the section of light-strip 4 of 7 four jiaos of light guide plate
1, pcb board 2 is arranged in coating 1, and light-strip 4 is fixed on pcb board 2 away from the side of light guide plate 7.Light-strip 4 is by wide and high
Two sides for constituting are respectively arranged with a LED 3.The incident side of light guide plate 7 sets one.Light guide plate 7 and light-strip 4 are all
It is rectangle.
The utility model is exemplarily described above in association with accompanying drawing.Obviously, the utility model is implemented not
Limited by aforesaid way.As long as employ the various unsubstantialities that method design of the present utility model and technical scheme are carried out
Improvement；Or it is not improved, above-mentioned design of the present utility model and technical scheme are directly applied into other occasions, at this
Within the protection domain of utility model.
