Soaking plate 10 is the vacuum cavity that an inwall has fine structure, and generally by metal, such as copper, aluminium etc. are made.
When heat is by heat source to evaporating area, the coolant in cavity starts to produce coolant after being heated in the environment of rough vacuum
Gasification phenomenon, now absorb heat energy and rapid spatial expansion, the cooling medium of gas phase quickly fills with whole cavity, works as gas phase
Working medium will produce the phenomenon of condensation when touching a cold region of comparing.Discharged by the phenomenon for condensing tired in evaporation
Long-pending heat, the coolant after condensation can be returned at evaporation thermal source by the capillary channel of micro-structural, and this running will be in cavity
Going round and beginning again is carried out.
Each heat radiation conduit 11 is connected using the operation principle of above-mentioned soaking plate 10 with soaking plate 10, carries out Homogeneouslly-radiating.
Radiator 3 is fixedly connected on the lower end of the inside of housing；The upper end of housing is provided with more than one air outlet, lower end
More than one air inlet is provided with, air pressure different principle different by gas temperature is produced in the inside of LED lamp housing
Gas flow paths, are fully exchanged heat from bottom to top, reach preferable radiating effect.It should be noted that LED lamp housing
The interior part from radiator more than 3 can turn into stream of hot air circulation passage.
In order to be more directly delivered on radiator 3 to the heat that LED light source module 4 is produced, the base of LED light source module 4
Plate is fixedly connected in soaking plate 10, and uniform conductive is carried out by soaking plate 10.
In order to promote the cold air for entering housing to produce heat exchange, the cup of the reflector 7 of LED lamp with hot air as early as possible
Bottom is fixedly connected with substrate, and rim of a cup is placed in the bottom interior edge of radiator 3, and thus the bottom up from housing is by reflector 7
Effective heat transfer space is constituted to radiator 3, heat transfer effect is improved.
Wherein substrate is ceramics, aluminium base or copper base, improves thermal conductivity.
In order to LED light source module 4 is formed into effective heat-dissipating space, and the heat-dissipating space is symmetrical, uniform, all radiating tubes
Class cylinder is surrounded, light source module is in center.
In order to heat is exchanged with the effective of cool ambient air in improving radiating tube, space is left between two neighboring radiating tube,
The free convection of air is improved, heat-conducting effect is improved.
Uniform heat transfer effect is formed in uniform natural convection air passage, LED lamp housing in order to be formed, works as air-out
When mouth is for multiple, all air outlets are uniformly distributed, and the hot-air after heat exchange can be discharged uniformly.
Ibid, when air inlet for it is multiple when, all air inlets are uniformly distributed, and cold air to be exchanged heat can be even into,
Reach each position of housing.
Superconductive medium of the invention be can phase transformation superconductive liquid, by the gas phase interconvertibility of superconductive liquid, and itself
Gravitational effects, realize the quick conduction of superconductive liquid, and the flowing in radiating tube, and then improve radiating effect.
In order to preferably install the LED lamp, each component of lamp interior is changed, housing is upper including what is be screwed
Housing 2 and lower house 9, take the housing of LED lamp apart by screw.
During installation, it fixes LED light source module 4, LED light source module plastic parts 5 and fixes by M2.5X6 countersunk head screws 6
On radiator 3, Heat Conduction Material is scribbled between LED light source module 4 and radiator 3, optics reflector 7 is fixed on LED
Light source module is fixed on plastic parts 5 in correspondence notch, and cooperation optics pressure ring 8 passes through screw thread by optics reflector
7 is locked；Radiator 3 is fixed on the upper shell 2 of light fixture by M3X10 countersunk head screws 1；By M3X10 countersunk head screws 1 by lamp
The upper shell 2 and lower house 9 of tool are fixed.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for the skill of this area
