When the present invention uses, LED lamp energising work, LED illuminator is luminous, and LED chip work is produced
Raw amount of heat, heat passes to heat conduction light source substrate, and most heat passes through heat conduction light source substrate
Bottom surface be conducted to radiating shell and come out in heat radiation mode, a part of heat is through at the bottom of heat-conducting substrate
Surface, portion and shell inner surface distribute in the heat radiation radiant chamber of housing, in heat radiation radiant chamber
Hot-air gives off through the heat radiation side opening of surface of shell, and cold air carries out cold from heat radiation side opening simultaneously
Thermal convection current exchanges, and chamber inner surface so can be made to amass heat the dissipating by surface of shell radiated
Hot side opening gives off；Directly discharged by radiating shell outer surface between another part.Use this
The cavity type radiator structure of sample, the technical program compared with prior art, has a following beneficial effect:
One, cavity design limited heat sink material can be made to accomplish the peripheral hot Free up Memory of radiator is
Greatly.
Two, the heat radiation side opening of surface of shell can make cavity inner surface amass heat and external world's sky of radiation
Gas carries out cold and hot exchange, makes cooling surface area in cavity become effective area of dissipation, thus in cavity,
Outer area is added accomplishes that lamp casing heat effective free list area is maximum.
Three, heat radiation side opening is had around heat radiation cavity, in can being the heat radiation cavity of light fixture, outside cavity
The heat of surface area radiation runs through radiating shell side opening and discharges.
Four, forming by thermal conductive metallic material die casting or stretching due to housing, the flange of housing is by portion
Point heat passes to the radiating fin on housing and housing, radiating fin increase the area of dissipation of housing from
And added quickly the speed of heat radiation.
Above skill upgrading radiating effect, it is ensured that LED lamp works long hours, effectively extend LED
Light fixture service life.Light fixture can be made to accomplish bigger heat radiation power with little heat sink material simultaneously,
Production cost greatly reduce, simultaneously can the volume of light fixture do less, weight is lighter, hidden
Tibetan property is more preferable, so that the application scenario of light fixture is more extensive, market potential is huge.Meanwhile, housing can
Protection LED power and luminous body, and have both heat sinking function, it is achieved the design on one-object-many-purposes way, reduces
Arrange independent radiator to dispel the heat for LED illuminator, save production cost, and good looking appearance.
