Refer to Fig. 1 and Fig. 2, the cooling mechanism 100 of the light fixture of embodiment of the present invention, comprise heat dissipation plate 110, convection cell 120 and compressor 130, compressor 130 is for generation of air-flow, convection cell 120 is for guiding to heat dissipation plate 110 by air-flow, and heat dissipation plate 110 is for absorbing the heat of the heat generating components generation of light fixture.
Heat dissipation plate 110 is circulus.Heat dissipation plate 110 is made up of Heat Conduction Material, and heat dissipation plate 110 comprises outer shroud 111, inner ring 113 and multiple demarcation strip 115.Outer shroud 111 is set in the radial outside of inner ring 113, and all there is spacing between the periphery of the periphery of outer shroud 111 and inner ring 113, to form the gap 116 of annular.Multiple demarcation strip 115 is disposed in gap 116, and the two ends of each demarcation strip 115 are fixedly connected with inner ring 113 with outer shroud 111 respectively, so that gap 116 is separated into multiple grid 117.
Specifically in the illustrated embodiment in which, heat dissipation plate 110 is circular ring, and the inner ring 113 of heat dissipation plate 110 is arranged with outer shroud 111 is concentric.Because the inner ring 113 of heat dissipation plate 110 is arranged with outer shroud 111 is concentric, make the gap 116 between inner ring 113 and outer shroud 111 comparatively even, thus make the thermal diffusivity of heat dissipation plate 110 comparatively even.
Further, multiple demarcation strip 115 spaced set, and all arrange along the radial direction of heat dissipation plate 110, to form the identical grid of multiple size 117.Because multiple grid 117 size is identical, so that improve the heat dissipation uniformity of heat dissipation plate 110 further.
See also Fig. 3 and Fig. 4, convection cell 120 is circulus.Convection cell 120 is fixedly connected with heat dissipation plate 110, and convection cell 120 comprises the inner peripheral 121 inside being positioned at and is positioned at outside and the outer peripheral edge 123 relative with inner peripheral 121.Convection cell 120 has air inlet 124, convection channel 125 and gas outlet 126.Air inlet 124 is connected with convection channel 125, convection channel 125 along the radial cross-section of the circumferential penetrative convection ring 120 of convection cell 120, and around the inner peripheral 121 1 weeks of convection cell 120.Gas outlet 126 is located on the inner peripheral 121 of convection cell 120, and rounds along the axis of convection cell 120.Gas outlet 126 is obliquely installed relative to the axis of convection cell 120, and towards gap 116.
Specifically in the illustrated embodiment in which, convection cell 120 is circular ring, the concordant setting corresponding to the lateral wall of the outer shroud 111 of heat dissipation plate 110 of the outer peripheral edge 123 of convection cell 120.Due to the concordant setting corresponding to the lateral wall of the outer shroud 111 of heat dissipation plate 110 of the outer peripheral edge 123 of convection cell 120, the air-flow avoiding the gas outlet 126 of convection cell 120 to blow out flows out from the gap between convection cell 120 and heat dissipation plate 110, thus improves the radiating efficiency of cooling mechanism 100 further.
It should be noted that, in the present invention, " annular " " ring-type " is not refer in particular to annular, and refers to and be similar to ring seal structure, and " annular " " ring-type " comprises ellipse, circle, polygon etc.
Such as, in other embodiments, heat dissipation plate 110 is the circulus of polygon or ellipse, and the inner ring 113 of heat dissipation plate 110 is arranged with outer shroud 111 is concentric.Convection cell 120 all corresponds to identical polygon or the circulus of ellipse, the concordant setting corresponding to the lateral wall of the outer shroud 111 of heat dissipation plate 110 of the outer peripheral edge 123 of convection cell 120.
Further, gas outlet 126 is 30 ~ 45 degree relative to the axial angle of inclination of convection cell 120.When gas outlet 126 is 30 ~ 45 degree relative to the axial angle of inclination of convection cell 120, makes the air-flow overwhelming majority blown out from the gas outlet 126 of convection cell 120 blow to the gap 116 of heat dissipation plate 110, thus make the thermal diffusivity of cooling mechanism 100 better.

Further, the cooling mechanism 100 of light fixture also comprises the outer container 150 for the protection of compressor 130, and outer container 150 is the cylindrical shell of both ends open, and covers on compressor 130, and outer container 150 is air entry away from the opening of convection cell 120.
Further, be provided with Air Filter (not shown) outside the air entry of outer container 150, extraneous air enters into compressor 130 by Air Filter.Be provided with Air Filter outside air entry due to outer container 150, prevent a large amount of dust from blowing into the inside of light fixture by cooling mechanism 100, and affect the normal work of light fixture.
Further, the air entry of outer container 150 is also provided with Water-cooling circulating device (not shown) outward, for carrying out cooling process to the air entry ambient air of outer container 150.Because the air entry of outer container 150 is also provided with Water-cooling circulating device outward, thus the air of inspiration compressor 130 is cooled, make the gas flow temperature blowing to heat dissipation plate 110 lower, thus improve the radiating efficiency of cooling mechanism 100 further.
When adopting above-mentioned cooling mechanism 100 to dispel the heat, the wind inlet of a large amount of air from compressor 130 sucks by compressor 130, air is pressurized subsequently, be blown in the convection channel 125 of the annular of convection cell 120 by the air inlet 124 of convection cell 120, and by the gas outlet 126 of annular, the air-flow after supercharging sprayed with circular trace.The flowing of air can cause the change of air pressure, the low-pressure area of an air can be formed below the gas outlet 126 of the annular of convection cell 120, owing to creating negative pressure in air, lower air is inhaled in the intermediate throughholes of convection cell 120 automatically, flow in top towards convection cell 120, form larger wind-force, so circulation is final forms one continual cold air stream.
