LED flat lamp is a kind of lighting that illumination market is emerging in recent years, it has efficiently, environmental protection, long-lived combining Close product advantage, the most extensively by the favorable comment of consumer.

LED flat lamp has wide range of applications, and is primarily adapted for use in the room lightings such as parlor, bedroom, corridor, view balcony.

Compared with other lighting, LED flat lamp has lot of advantages: LED flat lamp is long for service life.Incandescent lamp, Fluorescent lamp, halogen tungsten lamp are to use electronics light field radioluminescence, and filament light-emitting easily burns, the feature such as heat deposition, optical attenuation, and Use LED flat lamp volume little, lightweight, epoxy encapsulation, high-strength mechanical shock and vibrations can be born, the most fragile Broken, average life span reaches 100,000 hours, and LED flat lamp can be substantially reduced the maintenance expense of light fixture up to 5-10 service life With, it is to avoid often change the hardship of lamp.

But, present flat lamp is spliced by direct section bar and section bar, has light leakage phenomena；And section bar and section bar splice, knuckle It is the sharpest keen, in installation process, easily scratches hand.

Existing LED flat lamp has following deficiency or a shortcoming:

1. directly section bar splicing, has light leak；

2. use black shading rubber belt, be attached to corner, the most temporarily solve light leak, but its processing is cumbersome, Can not completely touch, there is also light leak, it is also possible to can forget patch shading rubber belt and do over again, shading rubber belt may produce During can be crushed and there is light leak etc.；

3. using soldering frame directly to weld, outward appearance is the most unsightly.

Summary of the invention

In order to solve above-mentioned technical problem, it is an object of the invention to provide a kind of Corner Seal part and use the close of this seal Encapsulation method, this seal and use the encapsulating method of this seal have seamless link, without light leak, install safety etc. spy Point.

It is an object of the invention to be achieved through the following technical solutions:

A kind of Corner Seal part, for sealing LED flat lamp, comprising:

First lath；

Second lath, the second described lath and the first lath be arranged in parallel, and the second lath is longer than the first lath；

First connector, the first described connector connects the first lath and the second lath, and the first described connector is located at First lath and the one end of the second lath；

Corner block, described corner block and the first connector are connected by the second connector, and described corner block is wedge shape Block, the cross section of described wedge is fan-shaped, and described fan-shaped central point is near the first connector direction.

Present invention additionally comprises the method using above-mentioned Corner Seal part sealing LED flat lamp, specifically include following steps:

S1, inserts LED flat lamp frame stitching portion by Corner Seal part along 45 degree of angles；

S2, covers the backboard of LED flat lamp and fixes；

S3, covers the connecting plate of LED flat lamp and fixes, and described connecting plate is triangle, is located at the limit of LED flat lamp The top of the side, stitching portion of frame.

By the technical scheme of the invention described above, the Corner Seal part of the present invention and use the encapsulating method of this seal to have Following beneficial effect:

(1) light leakage phenomena of section bar splicing mouth, appearance looks elegant, air are solved；

(2) production process is simple, it is not easy to omits Corner Seal part and causes doing over again；

(3) use plastic seal to turn fillet, the infringement to human body in installation process can be avoided.

Detailed description of the invention

Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in detail:

As depicted in figs. 1 and 2, a kind of Corner Seal part 10, for sealing LED flat lamp, prevent light leak.Comprising:

First lath 1, the first described lath 1 is used for preventing piece light leak.The first described lath 1 is connecting away from first The other end of part 5 is provided with triangular groove 11, and the setting of triangular groove 11 is easy to fix, and makes Corner Seal part 10 more steady Fixed.

Second lath 2, the second described lath 2 be arranged in parallel with the first lath 1, and the length of the second lath 2 is longer than the first plate The length of bar 1.Second lath 2 is mainly used in positioning action, makes whole to make the more stable location of Corner Seal part 10..
