And be formed with accommodation space, described substrate is installed in described accommodation space, described radiating subassembly include with
The radiating bottom plate of connection fixed by described lampshade, and described substrate is attached at the bottom of described radiating bottom plate, described
The top of radiating bottom plate is provided with some and described LED light source position heat-sink unit one to one.
Further, described heat-sink unit includes heat accumulation boss, if being set side by side with on described heat accumulation boss
Dry radiating fin；Described radiating bottom plate, described heat accumulation boss and corresponding described radiating fin are by being cast into
Type is integrated.
Further, the center being positioned at the described radiating fin in the middle of each described heat accumulation boss is all provided with
It is equipped with heating column.
Further, the thickness of described heat accumulation boss is at least 1 millimeter.
Further, between two the described radiating fins of arbitrary neighborhood on same described heat-sink unit
Spacing is 0-100 millimeter.
Further, the area of dissipation of each described radiating fin all at least 10 square millimeters.
The beneficial effects of the utility model are: the cooling LED module one to one that this utility model provides, logical
Cross and some and LED light source position heat-sink unit one to one is set on the top of radiating bottom plate, work

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
The cooling LED module one to one of one as shown in Figure 1 to Figure 3, including lampshade 1, radiating subassembly,
Substrate 2 and the some LED light sources 3 being packaged on substrate 2, lampshade 1 is connected also hermetically with radiating subassembly
Being formed with accommodation space, substrate 2 is installed in this accommodation space, and radiating subassembly includes fixing with lampshade 1
The radiating bottom plate 4 connected, substrate 2 is attached at the bottom of radiating bottom plate 4, and the top of radiating bottom plate 4 is arranged
There are some and LED light source 3 heat-sink unit 5 one to one, position, radiating bottom plate 4 and heat-sink unit 5
Aluminum alloy materials is all used to be made.
Heat-sink unit 5 includes heat accumulation boss 51, it is preferable that in order to heat accumulation effect is more preferable, heat accumulation boss 51
Thickness be at least 1 millimeter；Some radiating fins 52 it are set side by side with on heat accumulation boss 51, same scattered
Spacing between two radiating fins 52 of arbitrary neighborhood on hot cell is 0-100 millimeter, each radiating fin
The area of dissipation of sheet 52 all at least 10 square millimeters, thus ensure that filling of radiating fin 52 and air
Tap is touched.In order to improve heat-conducting effect, radiating bottom plate 4, heat accumulation boss 51 and corresponding radiating fin 52 lead to
Cross die cast to be integrated.Preferably, each heat accumulation boss 51 is set side by side with 3 radiating fins 52,
And the center being positioned at the radiating fin 52 in the middle of each heat accumulation boss 51 is provided with heating column 53,
By arranging heating column 53, further increase heat-conducting effect of the present utility model.
When the heat that LED light source 3 produces cannot be discharged in time through radiating fin 52, this part is the most timely
Conduction will be put aside on heat accumulation boss 51 to the heat of radiating fin 52, utilizes heat accumulation boss 51 to delay
Rush this partial heat, both effectively prevent heat and in accommodation space, caused LED light source 3 because accumulating
Damage, also increase effectively the temperature difference between the bottom of radiating fin 52 and its top simultaneously, thus be conducive to
Improve the coefficient of heat transfer so that radiating effect is more preferable.
In one embodiment, some radiating fins 52 shape on heat accumulation boss 51 differs and is one
Body chemical conversion type is arranged, it is ensured that air is fully contacted with radiating fin 52, and radiating effect is more preferable.
The cooling LED module one to one that this utility model provides, by arranging on the top of radiating bottom plate 4
Some heat-sink unit 5 one to one, position with LED light source 3, utilize each heat-sink unit 5 during work
Corresponding LED light source 3 is carried out independent heat radiation, not only contributes to give full play to the effective of each radiating fin 52
Area, improves heat conduction velocity and convection transfer rate, and each several part heat radiation is more uniformly distributed,
Heat dispersion is more preferable；Additionally, single LED light source 3 is dispelled the heat by each heat-sink unit 5 is independent,
It is also beneficial to reduce the area of radiating fin 52, therefore compared to traditional LED module, this utility model
Overall volume less, weight is lighter.
The above is only better embodiment of the present utility model, therefore all according to this utility model patent application
