Description

LED lamp
Technical field
The present invention relates to a kind of LED lamp, specifically refer to a kind of LED lamp with radiator structure.
Background technology
LED (LightEmittingDiode), i.e. semi-conductor electricity light source, light emitting diode, also referred to as semiconductorLamp, is a kind of electric light source without filament, is directly luminous energy electric energy conversion.
The feature that LED light fixture has is energy-conservation, the life-span is long, has avoided often needing the trouble that more changes the bulb, is subject toIncreasing user's favor. But the heat dissipation problem of LED lamp is also Important Problems, heat dissipation problem is tightHeavily have influence on light efficiency and the life-span of LED light source. Traditional LED lamp, its base that LED light source is housed generally allBe the cylindrical shape of sealing, make like this base inner air cannot be in time and the circulation of air of outside, cause looseThe thermal efficiency is low, causes LED light source and power supply excess Temperature, thereby has had influence on light efficiency and the life-span of LED. ExistingAlthough also have louvre at the LED lamp base having, for preventing dust protection against the tide, its louvre is less,Cause the problems such as heat radiation is unobstructed not, this also will have influence on the service life of LED lamp.
Summary of the invention
Based on this, be necessary to provide a kind of radiating efficiency high, the LED lamp of dust and moisture.
This LED lamp comprises: the substrate of the integrated LED of the being packaged with lamp pearl in surface, be electrically connected with LED lamp pearlThe base of control panel and connection substrate. The switch that base comprises multiple louvres and matches with louvreSheet, switch plate is made up of shape memory alloy material. Switch plate be heated while reaching preset temperature value, can produce toAway from the Bending Deformation of louvre direction.
In an embodiment, switch plate is arranged at louvre edge therein.
In an embodiment, base outer wall is connected with many radiating fins therein.
In an embodiment, preset temperature value is 45 DEG C therein.
In an embodiment, louvre is square therein.
In an embodiment, between substrate and base inner wall, scribble heat conductive silica gel therein.
In an embodiment, base is tubulose therein, and louvre is along the arranged radially of base.
In an embodiment, base inner wall has several inwardly protruded holding sections therein, and substrate edges is establishedFluted, groove is arranged in holding section.
Above-mentioned LED lamp, at normal temperatures, switch plate can seal louvre, makes the state of base in sealing.In the time turning on LED lamp, base and switch plate temperature can raise gradually. Because switch plate is by marmemMaterial is made, therefore being heated to reach after preset temperature, switch plate produces to the Bending Deformation away from louvre direction,Louvre is opened, improved radiating efficiency. And when LED lamp does not use, switch plate can be by louvreSealing, is conducive to reduce dust and protection against the tide, can improve LED lamp radiating efficiency and security.
Switch plate is arranged on louvre edge and can more effectively louvre is sealed and be opened. Be arranged on baseMany radiating fins on outer wall can provide larger area of dissipation to help base heat radiation. Between substrate and baseScribble heat conductive silica gel and can reduce the thermal resistance that heat transmits, can improve heat transfer efficiency.

Detailed description of the invention
As depicted in figs. 1 and 2, the structural representation of its LED lamp 10 that is an embodiment of the present invention andThe exploded perspective view of Fig. 2 LED lamp 10 of the present invention, wherein giving tacit consent to Fig. 1 is LED lamp 10 louvres 131The structural representation of closed state is general state.
This LED lamp 10 comprises: surface the integrated LED of being packaged with lamp pearl 111 substrate 110, with LED lampThe control panel 120 that pearl 111 is electrically connected and the base 130 of connection substrate 110. Substrate 110 edges are provided with recessedGroove 112, scribbles heat conductive silica gel between substrate 110 and base 130 inwalls. Base 130 comprises multiple louvres131 and the switch plate 132 that matches with louvre 131, under general state, switch plate 132 can be by heat radiationHole 131 is sealed. Wherein, louvre 131 can be arbitrary shape, preferably square. Switch plate 132Be arranged at louvre 131 edges. Base 130 outer walls can also be connected with many radiating fins 133 to improveArea of dissipation. Base 130 is tubulose, preferably circular tube shaped. Louvre 131 along base 130 radiallyArrange, preferably equally spaced evenly distributed. Base 130 inwalls have several inwardly protruded holding sections134, holding section 134 can be used for card establishes the groove 112 of substrate 110.
With reference to figure 3, it is the structural representation of LED lamp 10 louvre 131 open modes of the present invention simultaneously.Switch plate 132 is made up of shape memory alloy material, and switch plate 132 is in the meeting while reaching preset temperature value of being heatedProduce to the Bending Deformation away from louvre 131 directions, to open louvre. Wherein, preset temperature valueIt is 45 DEG C.
Above-mentioned LED lamp 10, under the normal temperature of general state, switch plate 132 can seal louvre 131,Make the state of base 130 in sealing. In the time turning on LED lamp 10, the heat that LED lamp pearl 111 producesBe gathered in the cavity that base 130 seals, at this moment base 130 and switch plate 132 temperature can raise gradually.Because switch plate 132 is made up of shape memory alloy material, and marmem has SME,It is heated reach preset temperature after can produce deformation. Switch plate 132 be heated reach produce after preset temperature toAway from the Bending Deformation of louvre 131 directions, louvre 131 is opened, thereby made base 130 inner emptyThe circulation of gas and outside air, makes heat rapid evacuation that LED lamp pearl 111 produces in air, improves heat radiationEfficiency. And when LED lamp 10 does not use, switch plate 132 can seal louvre 131, favourableIn reducing dust and protection against the tide, can improve LED lamp 10 radiating efficiencys and security.
Switch plate 132 is arranged on louvre 131 edges and can more effectively louvre 131 is sealed and be opened.Many the radiating fins 133 that are arranged on base 130 outer walls can provide larger area of dissipation to help base 130Heat radiation. Between substrate 110 and base 130, scribble heat conductive silica gel and can reduce the thermal resistance that heat transmits, can improveHeat transfer efficiency.
The above embodiment has only expressed the preferred embodiment of the present invention, and it describes comparatively concrete and detailed,But can not therefore be interpreted as the restriction to the scope of the claims of the present invention. It should be pointed out that for this areaThose of ordinary skill, without departing from the inventive concept of the premise, can also make some distortion andImprove, these all belong to protection scope of the present invention. Therefore, the protection domain of patent of the present invention should be with appendedClaim is as the criterion.
