Description
Technical field
The present invention relates to a kind of pendent lamp, specifically refer to a kind of high-power LED ceiling lamp with radiator structure.
Background technology
LED (Light Emitting Diode), i.e. semi-conductor electricity light source, light emitting diode, also referred to as semiconductor lamp, is a kind of electric light source without filament, is directly luminous energy electric energy conversion.
LED pendent lamp has energy-conservation, that the life-span is long feature, avoids the trouble often needing more to change the bulb, is subject to the favor of increasing user.Certainly, the same with every other LED lamp, the heat dissipation problem of LED pendent lamp is also Important Problems, and heat dissipation problem badly influences light efficiency and the life-span of LED light source.Traditional LED pendent lamp, its area of dissipation that lamp adapter assembly of LED light source is housed is less, although the lampshade of LED pendent lamp has larger area, but it is high light in order to reflex LED light source sends and prepares, therefore it does not have the heat sinking function to LED light source, so just 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, the also serious life-span having influence on LED pendent lamp.The LED pendent lamp had now is also equipped with the radiator of larger area, but it is also larger to have large-area radiator volume, causes and carries the problems such as inconvenient.
Summary of the invention
Based on this, be necessary to provide a kind of radiating efficiency high, portable LED pendent lamp.
This LED pendent lamp comprises: suspension rod, connect suspension rod radiator, be fastened in radiator and integrated substrate, the lampshade that is connected with radiator being packaged with LED lamp bead in surface.Radiator is made up of shape memory alloy material, the many fin that radiator comprises connecting ring and is connected with connecting ring, connecting ring one end is connected with suspension rod, and the connecting ring other end is connected with lampshade, and fin is heated when reaching preset temperature value and can produces to the Bending Deformation away from lampshade direction.
In one of them embodiment, heat conductive filler is filled with between substrate and radiator, substrate comprise integration packaging have the first surface of LED lamp bead, the adjacent with described first surface the 3rd and second relative with first surface, second forms have cavity with connecting ring, have gap between 3rd and connecting ring inwall, heat conductive filler is filled in cavity and gap.
Be inserted with a graphite core in heat conductive filler, and graphite core exceeds the end that connecting ring is connected with suspension rod near one end of suspension rod.
In one of them embodiment, fin comprises the deformations that connects connecting ring and is connected with deformations and the curved portions of arc in the form of sheets, curved portions inwall radius is equal with the exterior radius of lampshade circular arc, and deformations is heated when reaching above-mentioned preset temperature value and can be produced to the Bending Deformation away from lampshade direction.
In one of them embodiment, above-mentioned preset temperature is 45 DEG C.
In one of them embodiment, connecting ring is tubulose, and fin is along one end arranged radially be connected with lampshade of connecting ring.
In one of them embodiment, fin has multilayer along the axially-aligned of connecting ring.
In one of them embodiment, connecting ring inwall has several inwardly protruded holding sections, and substrate edges is provided with groove, and groove is arranged in holding section.
In one of them embodiment, the flange that one end that lampshade is connected with connecting ring has to extend internally, flange outward flange is connected with connecting ring.
In one of them embodiment, heat conductive filler is heat-conducting silicone grease.
Above-mentioned LED pendent lamp, the heat that LED lamp bead produces is by board transport in radiator and lampshade, and because marmem has SME, it can produce deformation after being heated.Fin Bending Deformation can be made after radiator is heated, make fin depart from lampshade, thus expand the area of dissipation of lampshade and radiator, abdicate multiple heat dissipation channel, accelerate the air circulation of lampshade outer surface, the heat rapid evacuation that LED is produced, in air, improves radiating efficiency.Have effect attractive in appearance, and when LED pendent lamp does not use, fin is retracted to cover surface, be conducive to the dust reducing cover surface, improve radiating efficiency, reduced volume is conducive to depositing and carrying simultaneously simultaneously.
Be filled with heat conductive filler between substrate and radiator, heat on substrate can be passed in radiator fast like this.The graphite core plugged in heat conductive filler, is more conducive to the heat in heat conductive filler to be dispersed into air from connecting ring upper end open.Because curved portions inwall radius is equal with the exterior radius of lampshade circular arc, when pendent lamp cuts out, fin can recover shape and is close to lampshade, when opening LED pendent lamp, deformations is heated and is bent upwards deformation, make fin away from lampshade, abdicate more passages for air circulation and gap, multi-layer heat dissipation sheet can provide larger area of dissipation, thus improves the radiating efficiency of pendent lamp.
