Abstract
The utility model discloses a kind of light conducting plate structures of no lamp backlight, including light conducting plate body, the light source incidence end of light conducting plate body is provided with reflecting slant, and being sticked in reflecting slant has reflectance coating, and light conducting plate body, which is located at below reflecting slant, is provided with the concave lens structure being adapted to it；The light source of concave lens structure and exterior terminal is opposite.The utility model can effectively solve the problem that light trough existing for the light conducting plate structure of existing no lamp backlight is a plane, light source direct irradiation is in the plane, reflecting surface directly is transmitted through, the problem of luminous point then in turn resulted in through reflective surface to site reflectance coating is big, dark space is serious.
Description
Technical field
Structure more particularly to a kind of light conducting plate structure of no lamp backlight the utility model is related to backlight source light conducting plate.
Background technology
With the development in backlight market, not only client is higher and higher to the quality requirements of backlight, and competes day increasingly
Acute market, client are also higher and higher to the cost cost performance requirement of backlight.Pressure or production of the terminal client under the pressure of cost
Product actual operation requirements are not high, may require that backlight supplier using few LED to make backlight, backlight LED quantity
Less light guide plate illumination effect will be difficult processing；Or the limitation due to 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 point light source has to add in LED
Light emitting angle, light guide plate illumination effect are just present with headlight phenomenon, the lamp eye that we often say, are also present between LED secretly
There is dark group in area, light-emitting zone, and LED exit positions occur intersecting eight words etc..Client can not thus be met to backlight source module
The requirement of display；The bad client of effect process will not receive or client is required to increase 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 conducting plate structure of no lamp backlight, solves existing no lamp backlight
Light trough existing for light conducting plate structure is a plane, and light source direct irradiation in the plane, is directly transmitted through reflecting surface, then through reflection
Face reflexes to the problem of luminous point that site reflectance coating in turn results in is big, dark space is serious.
Technical solution is used by the utility model solves its technical problem：A kind of leaded light of no lamp backlight is hardened
Structure, including light conducting plate body, the light source incidence end of light conducting plate body is provided with reflecting slant, and being sticked in reflecting slant has reflection
Film, light conducting plate body, which is located at below reflecting slant, is provided with the concave lens structure being adapted to it；Concave lens structure and exterior terminal
Light source is opposite.
Further, concave lens structure includes the concave mirror that two shared top margins are set back-to-back, and shared top margin is imploded arcs
Shape top margin, the base of two concave mirrors is concave arc base.
Further, the light source incidence end of light conducting plate body is provided with U-shaped notch, and the light conducting plate body back side is provided with leaded light
Frame, the both sides of reflecting slant closely U-shaped notch are each provided with one, and the lower section that guide-lighting frame is located at two reflecting slants is respectively set
It puts there are one allocation mouth, the left and right sides wall of concave mirror and the left and right sides inner wall of allocation mouth connect.
Further, the connecting position of the top of reflecting slant and light conducting plate body is globoidal structure.
The beneficial effects of the utility model：By setting concave lens structure, gone out after concave solar heat collecting by convex surface, astigmatism occurs and makees
With light is enable to irradiate light guide plate to the whole region of site reflectance coating, reduces dark space or even no dark space, luminous point is small, Neng Gouyou
It is a plane that effect, which solves light trough existing for the light conducting plate structure of existing no lamp backlight, light source direct irradiation in the plane, directly
Reflecting surface is transmitted through, the problem of luminous point then in turn resulted in through reflective surface to site reflectance coating is big, dark space is serious.Together
When, concave lens structure includes the concave mirror that sets back-to-back of two shared top margins, and shared top margin is concave arc top margin, two concave mirrors
Base be concave arc base, concave arc top margin optically focused, the light of LED light is radiated on two concave mirrors, is radiated at and leads
Tabula rasa body is directly refracted to away from the light of the concave mirror of site reflectance coating on the reflectance coating of site, and close light source is rolled over through concave mirror optically focused
It is mapped in reflecting slant, because the relation of the reflectance coating in reflecting slant is reflexed to again on the reflectance coating of site, further functions as reduction
The purpose of dark space so that structure is more reasonable.
Below with reference to drawings and examples, the utility model is described in detail.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.

The lower section in face 2 is provided with 5 structure of concave mirror being adapted to it；The light source of 5 structure of concave mirror and exterior terminal is opposite.Light conducting plate body 1
The back side be provided with site reflectance coating.
5 structure of concave mirror includes the concave mirror 5 that two shared top margins are set back-to-back, and shared top margin is concave arc top margin 7,
The base of two concave mirrors 5 is concave arc base.The light source incidence end of light conducting plate body 1 is provided with U-shaped notch 6, light guide plate
1 back side of body is provided with guide-lighting frame 3, and the both sides of reflecting slant closely U-shaped notch 6 are each provided with one, and guide-lighting frame 3 is located at
An allocation mouth 4 is each provided with below two reflecting slants, in the left and right sides wall of concave mirror 5 and the left and right sides of allocation mouth 4
Wall connects.The top of reflecting slant and the connecting position of light conducting plate body 1 are globoidal structure.
The utility model is exemplarily described above in association with attached drawing.Obviously, the utility model implements not
It is limited by aforesaid way.As long as employ the various unsubstantialities that the methodology of the utility model and technical solution carry out
Improvement；Or it is not improved, above-mentioned design and technical solution by the utility model directly apply to other occasions, at this
