Heat.
Publication No. CN101666439A discloses a kind of liquid cooling LED lamp, including lamp socket, the radiating that is arranged on lamp socket dress
The heating column put, be fixed on heat abstractor, described heating column is wound with flexible PCB along its side and top surface, described flexibility
Circuit board is gone into battle and is shown plurality of LEDs, and a light transmission outer cover is nested with LED periphery and is fixed on heat abstractor, outside described printing opacity
It is filled with liquid in the cavity that cover is formed with heat abstractor.The defect of described liquid cooling LED lamp is：Produce big when LED lights
The heat of amount, especially high-power LED, heat makes heat-conducting liquid expand, and then the pressure in light transmission outer cover is increased,
After pressure increases, the temperature of heat-conducting liquid continues to rise, and forms circulation, under long-time use, or even easily makes light transmission outer cover
Rupture, therefore, its power of described liquid cooling LED lamp is still subject to larger restriction.
Content of the invention
It is an object of the invention to provide a kind of liquid cooling type LED lamp, to reduce the pressure of LED cooling fluid generation, further
Improve LED power.
For reaching above-mentioned purpose, the solution of the present invention is：
A kind of liquid cooling type LED lamp, including lamp holder, lampshade and lamppost；Lampshade is arranged on formation cavity volume on lamp holder, fills out in cavity volume
Fill cooling fluid；Lamppost one end and lamp holder are tightly connected, and the other end installs LED chip, is placed in cooling fluid；In lamppost and lamp
Head connects the pressure-reducing cushioning device of one end setting and lamp holder sealing cooperation, and lamppost is movably mounted to lamp by pressure-reducing cushioning device
In head, install in lamppost and dropping equipment is arranged on the LED chip other end.
Further, described pressure-reducing cushioning device is the elastic rubber ring being arranged on lamppost.
Further, described elastic rubber ring is set to O-shaped elastic rubber ring.
Further, described elastic rubber ring and lamp holder sealing mating surface are set to arc；Described lamp holder madial wall arranges arc
Shape mounting groove, described elastic rubber ring arc mating surface is placed in mounting groove.
Further, described pressure-reducing cushioning device is set at least two.
Further, dropping equipment is made up of compressibility material.
Further, dropping equipment is sponge.
Further, groove is formed on lamppost.
Further, described dropping equipment is installed in groove.
Further, LED is also installed in groove drive.
Further, pre-buried connecting wire in lamppost, LED is driven one end to pass through connecting wire and is electrically connected with city, the other end
It is connected with LED chip by connecting wire.
After such scheme, the present invention is connected the pressure-reducing cushioning of one end setting and lamp holder sealing cooperation in lamppost with lamp holder
Device, lamppost is movably mounted in lamp holder by pressure-reducing cushioning device, installs setting step-down on the LED chip other end in lamppost
Device.When the heat that LED chip produces conducts to cooling fluid, the pressure that cooling fluid expanded by heating produces is absorbed by dropping equipment；
Meanwhile, cooling fluid expanded by heating produces pressure and makes pressure-reducing cushioning device produce elastic deformation, and makes lamppost displacement, absorb by
Cooling fluid expanded by heating produces pressure.Hence in so that liquid cooling LED internal pressure is unlikely to quickly to increase, and then can improve
The power of LED.

Specific embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in detail.
Refering to shown in Fig. 1 to Fig. 5, a kind of liquid cooling type LED lamp that the present invention discloses, including lamp holder 1, lampshade 2 and lamppost 3.
Lampshade 2 is arranged on formation cavity volume on lamp holder 1, fills cooling fluid 4 in cavity volume, and this cooling fluid 4 can select existing skill
The conventional cooling fluid of art, does not repeat herein.
Lamppost 3 one end and lamp holder 1 are tightly connected, and the other end installs LED chip 5, is placed in cooling fluid 4, LED chip
The heat of 5 generations conducts to cooling fluid 4.
It is connected the pressure-reducing cushioning device 6 of one end setting and lamp holder 1 sealing cooperation in lamppost 3 with lamp holder 1, as Fig. 2 and Fig. 3 institute
