The scheme of advanced optimizing is that the slot is square hole so that lens are in back font structure to realize air through slotWith convection current above and below the thermal vias of radiator.It can be good at solving the problems, such as dust accretions.
The scheme of advanced optimizing is, the bottom radiator, which is equipped with, is used to place the convex of installation LED light source mould group and lensColumn.It is easily installed LED light source mould group and lens.
The scheme of advanced optimizing is that the thermal vias inner surface is set as the smooth arc-shaped surface of evagination.Make dust will not heapProduct is on a heat sink.
The scheme of advanced optimizing is that the radiator left and right ends are equipped with cooling stand, the bottom end place of the cooling standHorizontal position lower than the horizontal position where lens.
The scheme of advanced optimizing is that the cooling stand is the mounting bracket with V-groove so that heat radiation module is fixed onOn the frame of lamps and lanterns.V-groove can be with the good face contact of bracket of lamp body, also can be the portion of mould group while playing fixed unfixedIt radiates in point heat transfer to lamp body.
A kind of LED lamp, it has above-mentioned New LED heat radiation module.
The scheme of advanced optimizing is that the LED lamp has multiple New LED heat radiation modules arranged side by side.
For the prior art, the utility model have the advantage that the utility model New LED heat radiation module andNot only better heat-radiation effect, radiator are not easy dust accumulation to LED lamp, substantially increase the service life of lamps and lanterns, substantially reduce simultaneouslyProduction cost.The utility model uses hollow out mode in terms of heat dissipation, and space is easy to generate convection current, radiate more preferably, simultaneouslyIt uses for a long time and is also not easy dust accumulation.
The utility model is more preferable in terms of heat dissipation, and can be good at solving the problems, such as dust accretions.
(1), the utility model radiator is by the way of thermal vias hollow out and lens Back Word type designs, heat dissipation effectMore preferably.
(2), the utility model space is easy to generate convection current, is not easy dust accumulation, will not influence heat dissipation, substantially increase lamps and lanternsService life, while greatly reducing production cost.

Specific embodiment
Specific embodiment is as follows:
It please refers to shown in Fig. 1-5, a kind of New LED heat radiation module, it includes radiator 1, LED light source mould group 2 and lens3, the LED light source mould group 2 is fixed on radiator 1, and lens 3 cover LED light source mould group 2；The radiator 1 is in axial directionBe arranged side by side have three groups be used to radiate and the rectangular thermal vias 11 of convection current with realizes heat dissipation and pass through cross-ventilation be effectively dischargedDust.The middle part of the LED light source mould group 2 described in the utility model is provided with corresponding with the thermal vias 11 on radiator 1Slot 21, the middle part of lens 3 are provided with slot 31 corresponding with the thermal vias 11 on radiator 1.The slot 31 is rectangularHole is so that lens 3 are in back font structure to realize thermal vias about 11 convection current of the air through slot 31 and radiator 1.
1 lower part of radiator described in the utility model is equipped with the pillar 12 for being used to place installation LED light source mould group 2 and lens 3.11 inner surface of thermal vias is set as the smooth arc-shaped surface of evagination.1 left and right ends of radiator described in the utility model, which are equipped with, to be dissipatedHot bracket 13, the horizontal position where the bottom end of the cooling stand 13 is lower than the horizontal position where lens 3.The cooling stand13 be the mounting bracket with V-groove so that heat radiation module is fixed on the frame of lamps and lanterns.V-groove can be fine with bracket of lamp bodyFace contact, the partial heat of mould group can be also transmitted on lamp body and be radiated while playing fixed unfixed.
Please refer to Fig. 6, shown in 7, a kind of LED lamp, it has above-mentioned New LED heat radiation module.The New LED dissipatesThe number of thermal module is X, X >=1 and be natural number.The New LED heat radiation module includes radiator 1, LED light source mould group 2With lens 3, the LED light source mould group 2 is fixed on radiator 1, and lens 3 cover LED light source mould group 2；The radiator 1 is along axisTo direction be arranged side by side have three groups be used to radiate and the rectangular thermal vias 11 of convection current with realizes heat dissipation and have by cross-ventilationEffect discharge dust.The middle part of lens 3 described in the utility model is provided with slot corresponding with the thermal vias 11 on radiator 131.The slot 31 is square hole so that lens 3 are in back font structure to realize that heat dissipation of the air through slot 31 and radiator 1 is logicalAbout 11 convection current of hole.1 left and right ends of radiator are equipped with cooling stand 13, the horizontal position where the bottom end of the cooling stand 13It sets low in the horizontal position where lens 3.For the mounting bracket with V-groove so that heat radiation module is fixed on the frame of lamps and lanternsOn.V-groove also can transmit the partial heat of mould group while playing fixed unfixed with the good face contact of bracket of lamp bodyIt radiates on to lamp body.
