Abstract
The utility model discloses a light guide plate structure of an LED (Light Emitting Diode) backlight source. The light guide plate structure comprises a light guide plate; LED luminous components are arranged at the side of the light guide plate; and zigzag grooves are arranged at the edge of the light guide plate near the LED luminous components. The zigzag grooves are uniformly arranged at the edge of the light guide plate and comprise V-shaped grooves, and a transverse side is arranged between the adjacent V-shaped grooves; and the included angles of the V-shaped grooves are 45-90 degrees. The positive surface of the light guide plate is a sanding surface, and the reverse surface of the light guide plate is a screen dot surface. The zigzag grooves of the light guide plate structure comprises the V-shaped grooves, and the transverse side is arranged between the adjacent V-shaped grooves; the included angles of the V-shaped grooves are 45-90 degrees so that lights emitted by the LED luminous components can be more effectively scattered, and emergent lights of the light guide plate are more uniform, thereby the utilization ratio of the LED luminance is increased, the energy source is saved, the cost is reduced, and the light guide plate structure is in line with the energy saving and environmental protection conception.
Description
Technical field
The utility model relates to a kind of LED-backlit source, particularly relates to the light entrance structures thereof of the LGP in a kind of LED-backlit source.
Background technology
Along with development of science and technology; LCD has been widely used in the electronic installation of various needs demonstrations; Melancholy liquid crystal material itself does not have the autoluminescence special efficacy, therefore needs to adopt special module backlight to display panels the backlight in order to display image to be provided.Module backlight generally includes a time, and for example light emitting diode is used for the light scattering that this light source sends is provided the LGP of uniform face emergent light.But because the light emitting diode size is less, and luminous too concentrated, therefore too concentrated after the light that light emitting diode sends injects LGP, though, still be easy to generate problems such as bright dark space or Eight characters bright line through the LGP scattering.On the LGP incidence surface, form various smooth incident structures to increase the inhomogeneity design of emergent light though have in the prior art, effect is not very good.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and the LGP in a kind of LED-backlit source is provided, and can effectively improve the angle of light degree, improves the light scattering uniformity coefficient.
In order to achieve the above object; The technical scheme that the utility model adopts is: the light conducting plate structure in a kind of LED-backlit source; Comprise LGP, the side of LGP is provided with the LED luminescence component, and described LGP is provided with the serrate groove near the edge of LED luminescence component.
Described serrate groove evenly is arranged at the LGP edge; Described serrate groove comprises V-shaped groove, is provided with a horizontal edge between the adjacent V-shaped groove; The angle angle of described V-shaped groove is 45～135 degree.
Described LGP front is a frosting, and reverse side is the site face.
Compared with prior art, the beneficial effect of the utility model is: be provided with the serrate groove at LGP near the edge of LED luminescence component, and the serrate groove comprises V-shaped groove, be provided with a horizontal edge between the adjacent V-shaped groove; The angle angle of described V-shaped groove is 45～135 degree, can carry out scattering by the more effective light that the LED luminescence component is sent, and makes that the emergent light of LGP is even; Improved the utilization ratio of LED brightness; The energy of practicing thrift has reduced cost, meets the notion of energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the local enlarged diagram in A place among Fig. 1.
Embodiment
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, so that the technical characterictic and the advantage of the utility model are carried out more deep annotation.
Like Fig. 1, shown in 2, the light conducting plate structure in a kind of LED-backlit source comprises LGP 1, and the side of LGP 1 is provided with LED luminescence component 2, and described LGP 1 is provided with serrate groove 3 near the edge of LED luminescence component 2.
Described serrate groove 3 evenly is arranged at LGP 1 edge; Described serrate groove 3 comprises V-shaped groove 31, is provided with a horizontal edge 32 between the adjacent V-shaped groove 31; The angle angle of described V-shaped groove 31 is 45～135 degree.
Described LGP 1 front is a frosting, and reverse side is the site face.
The angle angle of V-shaped groove 31 is 45～135 degree, and this angle is carried out scattering to incident light easily, and is luminous even, improved the utilization ratio of LED brightness, and the energy of saving has reduced cost, meets the notion of energy-conserving and environment-protective.
The content of mentioning in the foregoing description is not to be the qualification to the utility model, and under the prerequisite of the inventive concept that does not break away from the utility model, and any conspicuous replacement is all within the protection domain of the utility model.
