Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further described.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 1, a kind of Small Distance LED display of quick heat radiating, comprise casing 1, LED group 2 and face shield 3, it is inner that described LED group 2 is fixedly connected on casing 1, described LED group 2 comprises pcb board 21 and is arranged on some LED 22 in pcb board 21 front, and described LED 22 is rectangular array distribution, and pcb board 21 back side is integrated circuit face of weld 23, described integrated circuit face of weld 23 also has additional pyromagnetic heating radiator 24, and described casing 1 side is also provided with thermal vias 11.

The size of each described LED 22 of the present utility model is less than or equal to 1.0mm*1.0mm, and the spacing at the edge of two adjacent LED 22 is less than 1mm.Dot spacing is one of important technical parameter index of of LED display, and dot spacing is from the distance between two between pixel to reflect picture element density, and dot spacing and picture element density are the physical attributes of display screen; Information capacity is then the unit of quantity of the disposable shown information carrying capacity of unit area picture element density, and dot spacing is less, and picture element density is higher, and unit area is disposable, and to show information capacity more.Small Distance LED display can realize showing more high resolution pictures under comparable size, this performance becomes consumer's family expenses display device for LED display product and has meaning, and it have concurrently high colour gamut, high refresh rate, without the feature such as ghost, low-power consumption, meet very much at present user to the trend of parlor Showing Effectiveness On Screen requirement.

Because spacing between lamp group reduces, unit area is installed more LED lamp bead, and Small Distance LED display is higher to technological requirement, and the problems such as heat radiation, circuit will solve and also will spend cost more more than Large space product.The utility model has additional pyromagnetic heating radiator 24 at the LED lamp panel back side, and casing 1 side is also provided with thermal vias 11.Thermal magnon heating radiator is a kind of new radiator of brand-new heat radiation theory, and it utilizes thermal magnon material, and under thermal field environment, polarity can tactic feature, forms the thermal field air-flow of transverse shifting, thus reach the object of active heat removal in spreader surface.LED radiator applies the cold heat sink material of pyromagnetic heat sink material/magnetic, can realize LED100W light source radiator weight and be less than 2 kilograms, reduces weight metal 5-10 doubly, temperature rise is less than 20 degree, makes LED become true temperature low, and the life-span is long, cost is low, the new type light source afforded to use.In the heat sink material such as copper, aluminium, add the thermal magnon adjuvant of trace, namely can be made into thermal magnon heat sink material.Due to the proportion of principal ingredient in adjuvant and fine aluminium relatively, fusing point is all lower than 400 DEG C, and therefore the synthesis of material is very simple.Thermal magnon heating radiator belongs to classification of dynamically dispelling the heat, very strong with the exchange capacity of cold air.Radiating effect is much more effective than common copper, Aluminium Radiator.The weight of thermal magnon heating radiator is very light, and unit consumptive material is considerably less, and average every W power consumption only needs 8-15 gram of heat sink material, is only equivalent to the 1/5-1/10 of common Aluminium Radiator, greatly reduces the carbon emission amount in material manufacture process.The temperature rise general control of thermal magnon heating radiator at 5-15 DEG C, 25-30 DEG C lower than common Aluminium Radiator.Therefore go up, the light decay of LED is very little, substantially prolongs the serviceable life of LED light source.So the utility model can take into account LED group heat dissipation problem and serviceable life problem.

Preferably: described casing 1 adopts aluminum alloy material.Aluminium alloy density is low, but strength ratio is higher, has excellent thermal conductivity and corrosion resistivity, and simultaneously construction weight is compared steel plate materials and can be alleviated more than 50%.

Preferably: described face shield 3 adopts clear glass or transparent resin material, one end coordinates with casing 1 is hinged, and the other end adopts threaded.The wavelength of each LED luminescence can be variant, so the color of imaging has technicality in the visual field, adds that face shield 3 can gather wavelength and this color distortion is diminished, simultaneously can guard lamp group.And face shield 3 coordinates with casing 1 is hinged, convenient for maintaining, when LED group 2 needs replacing or wire short-circuiting to need repairing, can open face shield 3 and keep in repair.

Preferably: described thermal vias 11 place is provided with rain-proof eaves 12 and described casing 1 bottom surface is provided with hydrophobic groove 13.When display screen is mounted in outdoor environment, just must be subject to outdoor boisterous impact, in rainstorm weather, rainwater may be penetrated in casing 1 by thermal vias and installation fixed orifice, causes the situations such as lamp group short circuit electric leakage.The arranging of rain-proof eaves 12 and hydrophobic groove 13 can be dredged rainwater and be flowed away downwards, avoids lamp group to occur short circuit problem.

Preferably: on described face shield 3, be also provided with photoinduction equipment, for detecting the light intensity of external environment, then feeding back in control circuit, by regulating LED brightness to carry out adjusting screen brightness, thus reaching the object of energy saving.

Below described by reference to the accompanying drawings embodiment is only the preferred embodiment of the present invention, and the restriction not to protection scope of the present invention, and any improvement done based on the present invention's spirit all ought within scope.
