Abstract
The utility model discloses a light guide plate of a backlight source. The light guide plate comprises a light guide plate body, wherein a U-shaped groove is arranged at the end part of the light guide plate body; and notches are respectively arranged at both sides of the U-shaped groove. A saddle is arranged at one side of the U-shaped groove. A C-shaped groove with an upward opening is arranged at the bottom end of the U-shaped groove, and the opening of the C-shaped groove is larger than that of the U-shaped groove. A chamfer structure is arranged at the connecting part of the C-shaped groove and the U-shaped groove. The light guide plate of the backlight source, provided by the utility model, changes the flow direction of a glue, and increases the positioning area of an LED (Light-Emitting Diode) pin lamp and the contact area of the glue, thereby solving the problems that rays and splay rays are generated by the backlight source due to too much operation glue amount.
Description
Technical field
The utility model relates to backlight LGP field, the concrete backlight LGP that relates to a kind of single pin lamp.
Background technology
Traditional LED pin lamp lamp and backlight LGP (like Fig. 1, shown in Figure 2) location and light effects are bad; And structural requirement and the effect requirements to backlight will be increasingly high on the market; Along with the fast development of backlight technology, the whole illumination effect of backlight and performance requirement are with increasingly high.
The utility model content
The utility model aims to provide and a kind ofly can effectively improve the location of LED pin lamp and the backlight LGP of light effects.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is realized through following technical scheme:
A kind of backlight LGP comprises a light conducting plate body, and the end of said light conducting plate body offers a U-shaped groove, and the both sides of said U-shaped groove offer a recess respectively.
Further, a side of said U-shaped groove is provided with a saddle.
Further, the bottom of said U-shaped groove is provided with the C connected in star that an opening makes progress, and the opening of said C shape knot groove is greater than the opening of U-shaped groove.
Further, the junction of said C shape knot groove and said U-shaped groove is a chamfering structure.
Compared with prior art, the utlity model has following beneficial effect:
When backlight LGP of the utility model and the assembling of LED pin lamp, can make LED pin lamp under the situation that does not influence entire backlight source light, obtain more firm location.
The backlight LGP of the utility model has changed the direction that glue flows, and has increased the location of LED pin lamp and the contact area of glue, has solved because of operation glue amount too much makes backlight and has produced the phenomenon of ray and Eight characters line.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of instructions, below with the preferred embodiment and the conjunction with figs. detailed description of the utility model.The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 shows the structural representation of pin lamp backlight LGP in the prior art.
Fig. 2 is the assembly structure synoptic diagram of pin lamp backlight LGP and LED pin lamp in the prior art.
Fig. 3 is the structural representation of the pin lamp backlight LGP of the utility model.
Fig. 4 shows the pin lamp backlight LGP of the utility model and the assembly structure synoptic diagram of LED pin lamp.
Label declaration among the figure: 1, light conducting plate body, 2, the U-shaped groove, 3, recess, 4, saddle, 5, C shape knot groove, 6, chamfering structure, 7, LED pin lamp.
Embodiment
Below with reference to accompanying drawing and combine embodiment, specify the utility model.
Referring to Fig. 3, shown in Figure 4, a kind of backlight LGP comprises a light conducting plate body 1, and the end of said light conducting plate body 1 offers a U-shaped groove 2, and the both sides of said U-shaped groove 2 offer a recess 3 respectively.
Further, a side of said U-shaped groove 2 is provided with a saddle 4.
Further, the bottom of said U-shaped groove 2 is provided with the C connected in star 5 that an opening makes progress, and the opening of said C shape knot groove 5 is greater than the opening of U-shaped groove 2.
Further, said C shape knot groove 5 is a chamfering structure 6 with the junction of said U-shaped groove 2.
When pin lamp backlight LGP of the utility model and LED pin lamp 7 were installed dress, glue fixing can both be passed through in the left and right sides of said LED pin lamp 7 and bottom surface, thereby has increased location, stability and glue amount.Good supporting role has been played to the clubfoot of LED pin lamp 7 by said saddle 4 places.Can not exert oneself during clubfoot the coming off of the excessive LED of causing pin lamp 7.
Said chamfering structure 6 can prevent that glue from staying to lamp holder: glue flow to corner naturally and will stop automatically toward other local flowing in the process of a glue; Glue will paste whole LED pin lamp 7 and colloid face along saddle 4 in addition; Through the space in the middle of the saddle 4; Glue stops to flow, and the illumination effect in entire backlight source is guaranteed.
The preferred case study on implementation that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
