Detailed description of the invention
In order to solve the poor technical problem of existing LED lamp radiating effect, the invention provides the LED lamp that a kind of radiating efficiency is higher.
As shown in Figure 1, the LED lamp that one embodiment of the invention provides, comprising: heat abstractor 10 and LED group assembly 30, wherein,
Described heat abstractor 10, comprises substrate 11 and cover plate 12, and described substrate 11 and cover plate 12 cover the annular seal space being formed and have inlet 15 and liquid outlet 16, are connected with cooling liquid in described annular seal space;
Described LED group assembly 30, is fixed on the outer surface of substrate 11.
Substrate 11 and cover plate 12 should adopt heat conduction and the good material of insulation effect.LED group assembly 30 can be fixedly connected with substrate 11 by bolt, LED group assembly 30 with substrate 11 for tight fit contacts, therefore can fast by heat conduction to substrate 11.
In technical solution of the present invention, cooling liquid is connected with in the annular seal space of described heat abstractor, the heat conduction that LED group assembly produces is to substrate, the cooling liquid of substrate and flowing carries out heat exchange, cooling liquid after intensification is discharged through liquid outlet, the heat that LED group assembly produces is arranged fast by the cooling liquid flowed and is dissipated to device outside, and radiating efficiency is higher, and therefore the life-span of LED lamp also improves greatly.
Further, described LED lamp also comprises: the power supply 17 being fixed on cover plate 12, and described power supply 17 has the outer casing 18 of insulating heat-conductive.Outer casing 18 material is preferably insulating heat-conductive silica gel, has good sealing effectiveness simultaneously.Like this, power supply 17 and cover plate 12 close contact, the heat that power supply 17 inside produces conducts to cover plate 12 through outer casing 18, cover plate 12 carries out heat exchange with the cooling liquid of flowing, heat is arranged fast with the cooling liquid flowed and is dissipated to device outside, power supply has good radiating effect, and the life-span improves greatly.
Shown in Fig. 1, described cover plate 12 has the storage tank 19 of recessed cooling liquid, and described power supply 17 is positioned at described storage tank 19.Such design can increase the heat exchange area of power supply and cover plate, is equivalent to add the heat exchange area with cooling liquid, further increases radiating effect.Outer casing 18 can be placed in after in storage tank 19 at power supply and be formed through vacuum encapsulation.
As depicted in figs. 1 and 2, in order to further improve the radiating effect of LED lamp, described substrate 11 has one group of first radiating fin 13 in annular seal space, described cover plate 12 has one group of second radiating fin 14 in annular seal space, described one group of first radiating fin 13 and described one group of second radiating fin 14 are alternately arranged, and form multiple flow-guiding channel 20 along inlet 15 to liquid outlet 16 direction side by side.One group of first radiating fin 13 and one group of second radiating fin 14 have larger heat exchange area, cooling liquid uniform divided flows, water conservancy diversion that flow-guiding channel 20 can will pass into, heat conduction efficiency improves further, the heat that thermal source the produces liquid that is cooled is taken away in time and is discharged through liquid outlet 16, and the radiating effect of LED lamp is further enhanced.
Cooling liquid preferably adopts water, and the thermal capacitance of water is far superior to the heat eliminating mediums such as metal of the prior art, air, and economic environmental protection, takes facility.Can arrange valve 21 respectively outside inlet 15 and liquid outlet 16, control by the aperture of by-pass valve control 21 flow velocity sealing intracavity liquid, the operating temperature for LED group assembly 30 and power supply 17 selects suitable flow velocity.
In this embodiment, cold water uniform divided flows, water conservancy diversion that flow-guiding channel can will pass into, automatically supplementary principle is tended to according to hot water (after temperature of cold water rises) floating cold water, low level inlet input cold water, cold water heats up after the first radiating fin and the second radiating fin absorb heat, then flow to high-order liquid outlet to overflow, heat is taken out of.
In contrast to existing LED lamp, in this embodiment, cold water directly fully contacts with the second radiating fin with the first radiating fin, greatly reduce the repeatedly heat sink of heat from heat source generation through multistage medium and measure conduction, improve heat conduction efficiency, the operating temperature of LED group assembly and power supply is maintained in safe temperature range all the time, extends the service life of LED group assembly and power supply greatly.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
