Description
Technical field
The present invention relates to the heat abstractor of outdoor LED lighting apparatus.
Background technology
LED illuminator was just applied before 60 years, this illuminator relies on the service life of overlength and ultralow power consumption to be considered to the alternative source of light of following energy-saving illumination always, but LED illuminator is all generally be arranged in array combination to use, compact conformation, spatial dimension is little, usually be all mounted in closed space, current heat dissipation problem is the topmost factor affecting LED light source service life, in general the external skin temperatures safe range of LED illuminator is between 35 DEG C to 55 DEG C, light decay will be caused weak after 50 DEG C, external skin temperatures more than 55 DEG C after, the service life of LED can be had a strong impact on, especially for outdoor high-power LED (light emitting diode) lighting equipment, its heat radiation is even more important, but now conventional LED illuminator heat radiation is all dispel the heat simply by radiator, or fan auxiliary heat dissipation, namely when LED illuminator luminescence time, fan is dried heat radiation simultaneously, but lack temperature control device in common LED cooling system, such as, winter, ambient temperature was very low, time close to 0 DEG C, the temperature that outdoor LED illumination device produces is absorbed by outside air soon, even if fan does not work, within the temperature of LED illuminator also can remain on safe temperature range, now waste electric energy often left by fan, service life due to fan is limited, fan often leaves nature and will cause shorten service life, and for example, during the broiling summer, ambient temperature is up to 40 DEG C, even if LED illuminator is under the effect of fan, its surface temperature also even more may be increased more than 50 DEG C, the effect of fan cannot keep the temperature of LED illuminator in safe range, thus LED illuminator can be caused to damage.
Such as, Chinese patent Authorization Notice No. CN200986167Y, authorized announcement date on December 5th, 2007, disclose a kind of heat abstractor of high power LED illumination device, be fixed in lamp housing, the front side wall of heat dissipation tank is attached to the back side of circuit board of the light emitting diode of matrix arrangement and the left side of front side wall has exhaust vent, and the right side wall of heat dissipation tank is provided with fan, the arranged on left and right sides of lamp housing has air outlet and air inlet, and exhaust vent is communicated with air outlet by discharge pipe.Because have employed enclosed heat abstractor, and only at the side of heat dissipation tank dress fan and opposite side outputs air holes, make radiating effect better, thus allow to increase the service life of illuminating lamp.And for example, Chinese patent Authorization Notice No. CN202813287U, authorized announcement date on March 20th, 2013, disclose a kind of cooling system of lighting device, the cooling system of this lighting device passes through heat-conducting plate, lighting source and radiator and arrange nano heat-conductive heat radiation polymeric layer, solve the radiating effect of heat abstractor in prior art poor, heat abstractor is complicated, the technical problems such as the large and Heavy Weight of the volume of heat abstractor, the heat conduction and heat radiation performance achieving the cooling system of lighting device is excellent, good heat dissipation effect, and the heat abstractor of larger volume need not be used, even can eliminate the conventional radiating fin adopted in existing heat abstractor, the volume reaching whole LED light device reduces, the technique effects such as weight.Two kinds of above-mentioned heat abstractors all cannot detect LED illuminator external skin temperatures and regulate for testing result, therefore the temperature of LED illuminator accurately cannot be controlled in safe range, still can cause when temperature exceedes safe range that light decay is weak even damages LED illuminator.
