Abstract
The utility model discloses a leaking-proof light emitting diode (LED) backlight source which comprises a light guide plate. One side of the upper surface of the light guide plate is connected with one side of a diffuse membrane through a double faced adhesive tape, and the other side of the upper surface of the light guide plate is provided with a black silver shading membrane. The other side of the diffuse membrane is arranged on the black silver shading membrane, and the light guide plate under the black silver shading membrane is provided with a sealed straight cutting LED lamp position. The thickness of the straight cutting LED lamp position is smaller than that of the light guide plate, and an LED lamp is inserted in the straight cutting LED lamp position. Two sides of the lower surface of the light guide plate are respectively connected with reflection membranes through double faced adhesive tapes. The LED lamp is connected with a terminal through a wire. The leaking-proof LED backlight source overcomes the defects in the prior art that glass is easy to damage through collision, illumination effect is poor, glue leakage atomizes membrane paper or the light guide plate, using level of glue needs controlling at the assembly time, an the like. The leaking-proof LED backlight source has the advantages of being simple in structure, even in illumination, high in brightness, strong in adaptability, and high in assembling efficiency, does not need to control the using level of the glue, and the like.
Description
Technical field
The utility model relates to the LED-backlit source technology, is a kind of LED-backlit source of liquid-leakage preventing specifically.
Background technology
LGP is generally adopted in LED-backlit of the prior art source, and the LGP positive and negative is pasted diffusion barrier and reflectance coating with double faced adhesive tape and black silver-colored photomask respectively, be provided with led light source in LGP one side, led light source is by the electric wire splicing ear, when led light source adopts straight cutting LED lamp, mostly be man-made assembly, easily outstanding to exiting surface or reflecting surface, when outstanding to exiting surface, easily push up bad guest's glass, can't show, when outstanding to reflecting surface, then can't set level, affect light effect.In addition, when adopting straight cutting LED lamp, need glue to fix, the glue seepage can be brought the atomizing of film paper or LGP, makes demonstration backlight dimmed, because need glue to fix, man-made assembly need to be controlled the consumption of glue, directly affects packaging efficiency.
The utility model content
The purpose of this utility model is to overcome the deficiency that above prior art exists, provide a kind of simple in structure, luminous evenly, brightness is high, applicability is strong, packaging efficiency is high and need not to control the LED-backlit source of the liquid-leakage preventing of glue consumption.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of LED-backlit source of liquid-leakage preventing, comprise LGP, LGP upper surface one side connects diffusion barrier one side with double faced adhesive tape, LGP upper surface opposite side arranges black silver-colored photomask, be the diffusion barrier opposite side on the black silver-colored photomask, offer the straight cutting LED lamp position of sealing on the LGP below the black silver-colored photomask, the thickness of the Thickness Ratio LGP of straight cutting LED lamp position is little, the LED lamp inserts in the straight cutting LED lamp position, LGP lower surface both sides all connect reflectance coating with double faced adhesive tape, and the LED lamp passes through conductor terminal.
Preferably,The thickness of described LGP is 2.2mm, and the thickness of straight cutting LED lamp position is 2mm.
In order to prevent the glue seepage, preferred,Described straight cutting LED lamp position is the ampuliform structure, and straight cutting LED lamp position only has the outlet of a dress LED lamp.
Operation principle of the present utility model: a kind of LED-backlit source of liquid-leakage preventing, it is characterized in that: comprise LGP, LGP upper surface one side connects diffusion barrier one side with double faced adhesive tape, LGP upper surface opposite side arranges black silver-colored photomask, be the diffusion barrier opposite side on the black silver-colored photomask, offer the straight cutting LED lamp position of sealing on the LGP below the black silver-colored photomask, the thickness of the Thickness Ratio LGP of straight cutting LED lamp position is little, the LED lamp inserts in the straight cutting LED lamp position, LGP lower surface both sides all connect reflectance coating with double faced adhesive tape, and the LED lamp passes through conductor terminal.
When assembling, do not need to control the glue consumption, because straight cutting LED lamp position is hermetically-sealed construction, can effectively prevent the glue seepage, the thickness of the Thickness Ratio LGP of straight cutting LED lamp position is little in addition, can not push up bad exiting surface and reflecting surface, can make light source even, and brightness is high.
The utility model has following advantage and effect with respect to prior art:
1, the utility model has adopted the straight cutting LED lamp position that offers sealing on the LGP, the thickness of the Thickness Ratio LGP of straight cutting LED lamp position is little, have simple in structure, luminous evenly, brightness is high, applicability is strong, packaging efficiency is high and need not to control the characteristics such as glue consumption.
2, the straight cutting LED lamp position in the utility model is the ampuliform structure, and straight cutting LED lamp position only has the outlet of a dress LED lamp, prevents the glue seepage, has guaranteed illumination effect.
3, need not to control the glue consumption during the utility model mounted LED lamp, improved efficiency of assembling.
