Abstract
The utility model discloses a LED pixel lamp, comprising a lamp holder and a circuit board mounted in the lamp holder and provided with a LED, which is characterized in that the lamp holder is provided with a lampshade which forms a closed space with the lamp holder to seal the circuit board, and the lampshade and the lamp holder are clamped and fixed by a seal ring. The utility model overcomes the defects of the prior art, and provides a LED pixel lamp whose lamp holder and lampshade are plugged via tenon slots and the expansion of a seal ring, having simple structure, less installment process and low production cost, to avoid arranging screw holes on the lampshade and obtain beautiful lampshade appearance. The seal chamber of the LED pixel lamp is provided with a one-way valve, wherein when the circuit board generates heat, the high pressure in the lamp is exhausted by the one-way valve automatically to effectively avoid discharging the lampshade via internal pressure and prevent external water and gas from entering into the lamp, to realize effective water prevention.

[utility model content]
The utility model purpose is to have overcome the deficiencies in the prior art, provides to adopt the falcon groove to peg graft between a kind of lamp socket and the lampshade, and the sealing ring swelling, simple in structure, installation procedure is few, the LED pixel lamp that cost of manufacture is low.
The utility model is achieved through the following technical solutions:
A kind of LED pixel lamp comprises lamp socket, and the circuit board of band LED is housed in lamp socket, it is characterized in that described lamp socket is provided with and the lampshade of lamp socket formation enclosure space with the circuit board sealing, is fixedly clamped by sealing ring between described lampshade and the lamp socket.
Aforesaid LED pixel lamp is characterized in that described lamp socket is provided with air-vent, is equipped with in the described air-vent that fluid flows out in the enclosure space only and the check valve that can not flow to from the external world.
Aforesaid LED pixel lamp is characterized in that described lamp socket is provided with annular slot, and described lampshade is provided with the slotting falcon of annular of matching and pegging graft with annular slot, and described annular is inserted between falcon and the annular slot by described sealing ring swelling sealing.
Aforesaid LED pixel lamp is characterized in that described sealing ring cross section is the U-shaped cross section.
Aforesaid LED pixel lamp, it is characterized in that described check valve comprises the valve body of being made by soft elastic material, being provided with in the described valve body can be for the valve pocket of fluid flow, one end of described valve pocket is an openend, the other end outside be provided with can with this end unidirectional blocking of valve pocket with valve body be the feather valve door-plate of one.
Aforesaid LED pixel lamp is characterized in that the outside of described valve body is provided with and the integrated sealing ring of valve body.
Aforesaid LED pixel lamp is characterized in that described valve body made by rubber.
Compared with prior art, the utility model has following advantage:
1, adopt the falcon groove to peg graft between the utility model lamp socket and the lampshade, the sealing ring swelling, simple in structure, installation procedure is few, and cost of manufacture is low, has avoided screw hole is set on lampshade, makes the lampshade outward appearance perfect;
2, be provided with check valve in the utility model annular seal space, circuit board adstante febre, lamp inner high voltage are discharged from check valve automatically, effectively protect lampshade not released by the lamp internal pressure; And extraneous water, gas can not enter in the lamp, effectively waterproof.

[specific embodiment]
A kind of LED pixel lamp comprises lamp socket 1, and the circuit board 2 of band LED is housed in lamp socket 1, and described lamp socket 1 is provided with lamp socket 1 and forms the lampshade 3 of enclosure space with circuit board 2 sealings, is fixedly clamped by sealing ring 4 between described lampshade 3 and the lamp socket 1.
Described lamp socket 1 is provided with air-vent 101, is equipped with in the described air-vent 101 that fluid flows out in the enclosure space only and the check valve 5 that can not flow to from the external world.Described lamp socket 1 is provided with annular slot 102, and described lampshade 1 is provided with the slotting falcon 301 of annular of matching and pegging graft with annular slot 102, and described annular is inserted between falcon 301 and the annular slot 102 by described sealing ring 4 swellings sealing.Described sealing ring 4 cross sections are the U-shaped cross section.
Described check valve 5 comprises the valve body of being made by soft elastic material 501, being provided with in the described valve body 501 can be for the valve pocket 5101 of fluid flow, one end of described valve pocket 5101 is an openend, the other end outside be provided with can be with valve pocket 5101 these end unidirectional blockings be the feather valve door-plate 5102 of one with valve body 501.The outside of described valve body 501 is provided with and valve body 501 integrated sealing rings 5103.Described valve body 501 is made by rubber.
During installation, earlier check valve 5 is installed in the air-vent 101 of lamp socket 1, again circuit board 2 is installed on the lamp socket 1, through wires hole on the embedding lamp socket 1, the annular of lampshade 3 is inserted falcon 301 insert in the U-lag of sealing rings 4, be inserted into together again in the annular slot 102 of lamp socket 1 at last, compress and get final product.
In the use, lamp is inner can be owing to the circuit board heating produces pressure, and when pressure inside was higher than external pressure, gases at high pressure flowed into from the check valve openend, and the sealing elastic force that utilizes pressure reduction to overcome valve plates 5102 is washed valve plates 5102 open and flowed out.When ambient pressure was higher than internal pressure, valve plates 5102 was closed under sealing elastic force and differential pressure action, realized water-tight.
