Abstract
The utility model discloses an LED backlight source light guide plate, the inner wall of an LED installation pit of which is provided with glue storage troughs. After the glue storage troughs are added, the LED backlight source light guide plate leads glue for fixing an LED support to enter two glue storage troughs, thus greatly improving the phenomenon of headlight light ray generated by the glue.
Description
Technical field
The utility model relates to a kind of bracket LED (light emitting diode) backlight, and the LGP parts in particularly a kind of bracket LED backlight by increase the storage glue groove of two symmetries on the light trough structure of bracket LED, are eliminated the ray phenomenon that too much produces because of glue.
Background technology
At present under the situation that the backlight technology reaches its maturity, market to backlight visual effect require more and more highlyer, also be like this for the Frame lamp backlight that is in the market low side.And traditional Frame lamp backlight is because the reason of this body structure and assembling, and the luminous easy generation ray phenomenon of finished product can't satisfy the requirement of market to such backlight visual effect.
Shown in Figure 1A is existing bracket LED backlight LGP lamp pre-structure schematic diagram, bracket LED is fixed in the leaded light board slot by instant drying adhesive, but leave the fit-up gap because of LED and LGP side during the assembling of LED and LGP, glue can flow in the gap, when glue flow to LED side front end, as Figure 1B and when solidifying, LED front end and LGP connect into an integral body by glue, part light can be concentrated outgoing by LED front end wedge angle during the LED beam projecting, produces the ray phenomenon on backlight.
For this reason, demand is a kind of is not influencing the scheme of improving the backlight visual effect under the condition of cost.
The utility model content
Relatively poor at the existing luminous visual effect of bracket LED backlight, easily produce the problem of ray, the utility model provides a kind of LGP that can effectively improve the ray problem, and better luminous visual effect is provided.The utility model is achieved by following technical proposals: a kind of LED-backlit source LGP that can effectively improve the luminous visual effect of backlight is provided with storage glue groove at its LED installation pit position inwall.
After having increased storage glue groove, make the unnecessary glue that is used for fixing bracket LED enter two storage glue grooves, improved light ray phenomenon before the lamp that produces because of glue greatly.
Description of drawings
Figure 1A is an existing LED-backlit source LGP schematic diagram.
Figure 1B is the cross-sectional schematic of existing LED-backlit source LGP.
Fig. 2 A is the structural representation of LED-backlit of the present utility model source LGP.
Fig. 2 B is the structure cutaway view of the preceding state of storage glue of LED-backlit of the present utility model source LGP.
Fig. 2 C is the cutaway view of state behind the demonstration LED-backlit of the present utility model source light conducting plate structure storage glue
The specific embodiment
Frame lamp light trough structure of the present utility model is shown in Fig. 2 A, and being used on LGP 10 places in the position, hole 110 of LED has increased storage glue groove 101.
Wherein, shown in Fig. 2 B, this storage glue groove can be arranged on the middle part of position, hole 110, and the inwall of position, hole, edge is to LGP 10 inner extensions.
The form of described storage glue groove 110 can be to be symmetrical arranged, and the inwall that perhaps spreads all over position, whole hole stretches out as shown in Figure 3, and the glue when LED assembles flows and can flow in the storage glue groove, has avoided being subjected to polluting the backlight ray problem that produces because of the LED front end.
Claims (3)
1. a LED-backlit source LGP is characterized in that: be provided with storage glue groove at the LED installation pit position of LED-backlit source LGP inwall.
2. LED-backlit according to claim 1 source LGP is characterized in that: this storage glue groove is arranged on the middle part of cheating the position, extends to LGP inside along the inwall of cheating the position.
3. LED-backlit according to claim 1 source LGP is characterized in that: storage glue groove spreads all over the inwall of position, whole hole.
