Detailed description of the invention
In order more clearly to understand technology contents of the present utility model, describe in detail especially exemplified by following examples.
In Fig. 1 to Fig. 6, the direction of arrow in accompanying drawing is the flow direction of air.This radiating LED lamp lamps structure, comprise lamp main body 1 and LED chip, LED chip is arranged in the internal cavity of lamp main body 1, it is characterized in that, LED chip is communicated with outside air, and the arranged outside of LED chip has air port, and air port comprises air inlet 3 and air outlet 2, outside air is communicated in LED chip by air inlet 3, and this LED chip is communicated with outside air by air outlet 2.
LED chip can be strip source.Air inlet 3 is arranged at a side of LED chip, and air outlet 2 is arranged at the opposite side of LED chip.
LED chip can be annular light source.Air inlet 3 and air outlet 2 are around the periphery that is arranged at LED chip, and air inlet 3 is arranged at the below of air outlet 2.
Fitting structure also comprises shell and heat conduction backboard, and shell is provided with fin, and heat conduction backboard is close to shell.Outer surface and the inner surface of shell are fairing ace, inside has gone out LED chip cavity part, and all the other can reach ventilation effect, the advanced spraying coating process in surface makes that dust dirt etc. is more difficult is stayed by attached, also the air more easily being circulated washes away, thereby has avoided affecting because of the dirt that shell fin and heat conduction backboard are piled up the radiating effect of light fixture above.
At LED chip adstante febre, in light fixture, place's light-source chamber is packing less, in the time that lamp temperatures raises, Inside Air Temperature increases, and volumetric expansion has utilized hot-air to the physical principle rising, hot air to be discharged by air outlet 2, in order to fill the hot-air of loss, thereby cold air can nature enters air inlet 3 and enters light fixture below, be so also just naturally first the effect of inner air and outer air convection current, realize most economical self heat dissipation function.
