Description

Lampshade
Technical field
The present invention relates to a kind of lampshade, specifically refer to a kind of lampshade with radiator structure.
Background technology
Lampshade has the effect of optically focused, is widely used in LED.But in traditional LED, lampshade is all generally be located at below the larger lens of a slice, lampshade entirety can cover by such lens, makes lampshade be in a closed environment like this, cannot be ventilated.Make lampshade cannot play the effect of heat radiation to LED, cause radiating efficiency low, cause LED light source and power source temperature too high, thus had influence on light efficiency and the life-span of LED.
Summary of the invention
Based on this, be necessary the lampshade providing a kind of radiating efficiency high.
This lampshade comprises: the second heat sink that the first heat sink and the first heat sink are oppositely arranged and the multiple reflectors be connected between the first heat sink and the second heat sink.Reflector is connected one end with the first heat sink and is provided with the first rim of a cup, and reflector is connected one end with the second heat sink and is provided with the second rim of a cup.First heat sink is provided with and the first rim of a cup resigning hole one to one, and the second heat sink is provided with and the second rim of a cup light hole one to one.Second heat sink is provided with some louvres.
In one of them embodiment, between the first heat sink and the second heat sink, be connected with multi-disc fin.
In one of them embodiment, the second heat sink is provided with projection away from the one side of the first heat sink, and louvre has multiple and is distributed in projection.
In one of them embodiment, projection is hemispherical projections.
In one of them embodiment, fin is along the arranged radially of the first heat sink.
In one of them embodiment, the first heat sink and the second heat sink are circle.
In one of them embodiment, the first heat sink and the second heat sink are at the area equation perpendicular to the projection on the first heat sink direction.
In one of them embodiment, fin has two rings along the radial concentric arrangement of the first heat sink.
In one of them embodiment, light hole is arranged with lens.
Above-mentioned lampshade, when it uses in conjunction with LED, the first heat sink can absorb the heat that LED transmits quickly, because the first heat sink is connected with the second heat sink, and the second heat sink is provided with louvre, air can be entered between two heat sinks and by the heat between heat sink and shed.Open setting between first heat sink and the second heat sink, also can allowing air flow more unobstructed, thus improve radiating efficiency.
Lens card is located on the second heat sink, more space can be abdicated to louvre like this.Be arranged between two heat sinks multi-disc fin can increasing heat radiation area help lampshade heat radiation.The multi-disc fin be arranged between two heat sinks can provide larger area of dissipation to help lampshade heat radiation.Projection on second heat sink not only can increase area of dissipation, and the logical air of more multithread can be allowed to enter between two heat sinks, thus improves radiating efficiency.

Detailed description of the invention
As shown in Figure 1, it is the structural representation of an embodiment of the present invention lampshade 10.
This lampshade 10 comprises: the second heat sink 120 that the first heat sink 110 and the first heat sink 110 are oppositely arranged and the multi-disc fin 140 be connected between the first heat sink 110 and the second heat sink 120.Preferred first heat sink 110 and the second heat sink 120 are circle.Further, the first heat sink 110 and the second heat sink 120 are at the area equation perpendicular to the projection on the first heat sink 110 direction.Multi-disc fin 140 is along the arranged radially of the first heat sink 110, and preferred multi-disc fin 140 is radial evenly distributed along the arrangement of the first heat sink 110.Second heat sink 120 is provided with protruding 123 away from the one side of the first heat sink 110, and preferred protruding 123 is hemispherical projections, is distributed with multiple louvre 122 on protruding 123.
As shown in Figures 2 and 3: it is respectively the exploded perspective view of lampshade 10 two different visual angles.
This lampshade 10, except said structure, also comprises: be connected to the multiple reflectors 130 between the first heat sink 110 and the second heat sink 120.Reflector 130 is connected one end with the first heat sink 110 and is provided with the first rim of a cup 131, and reflector 130 is connected one end with the second heat sink 120 and is provided with the second rim of a cup 132.First heat sink 110 be provided with the first rim of a cup 131 one to one resigning hole 111, second heat sink 120 be provided with and the second rim of a cup 132 light hole 121 one to one.Second heat sink 120 is provided with some louvres 122.Fin 140 has two rings along the radial concentric arrangement of the first heat sink 110.Further, light hole 121 is arranged with lens.
When lampshade 10 is for being combined with LED, the first heat sink 110 can be close to be arranged on surface with on the substrate of LED lamp bead.Resigning hole 111 and the first rim of a cup can hold LED lamp bead by one_to_one corresponding.
Above-mentioned lampshade 10, when it uses in conjunction with LED, first heat sink 110 can absorb the heat that LED transmits quickly, because the first heat sink 110 is connected with the second heat sink 120, and the second heat sink 120 is provided with louvre 122, air can be entered between two heat sinks, therefore heat shed by the first heat sink 110 and the second heat sink 120.And above-mentioned lampshade 10 has larger area of dissipation than traditional lampshade 10, the more heat therefore it can shed.Open setting between first heat sink 110 and the second heat sink 120, also can allowing air flow more unobstructed, thus improve radiating efficiency.
Lens card is located on the second heat sink 120, abdicates more space, to improve radiating efficiency can to like this louvre 122.The multi-disc fin 140 be arranged between two heat sinks can provide larger area of dissipation to help lampshade 10 to dispel the heat.Projection 123 on second heat sink 120 not only can increase area of dissipation, and the logical air of more multithread can be allowed to enter between two heat sinks.Many rings fin 140 can provide larger area of dissipation to further increase radiating efficiency.
The above embodiment only have expressed the preferred embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
