-10
～10
-6
rice.
the thermal conductivity factor of described heat conduction composite plastic is between 1-10W/mK.
the plastic substrate of composite plastic can be in polyamide-based (PA), PET series (PET), epoxy resin (Epoxy Resin), polyimides system (PI), polyphenylene sulfide system (PPS) a kind of.The inorganic filler of composite plastic is a kind of in carbon element, oxide based, nitride based, hydroxide system.The lamp socket 2 of being made by nano composite plastics has good thermal diffusivity.
described lampshade 4 is made by Merlon (PC).PC is the amorphous polymer of almost colourless glassy state, has well optical and good hydrolytic resistance.Lampshade 4 forms integrated structure with lamp socket 3 by integrated extrusion molding, and combination between them is tight, sealing is good.Therefore the fluorescent tube that has lampshade 4 and lamp socket 3 to form has good water resistance.Because the composite plastic of lamp socket 3 is the same as with lampshade 4 being made of plastics, thereby they can adopt extrusion molding one-shot forming.Lampshade also can be made by the light transmission engineering plastics except PC.
described body 21 is towards the slightly protruding center to lamp housing, surperficial middle part of substrate 1 one sides.So that contacting of the upper surface of substrate 1 bottom and body 21 is more tight, make the air between the two the least possible, thereby be beneficial to the heat that LED lamp pearl 11 is produced, conduct to quickly lamp socket 3 and dispel the heat quickly.
in the cross section of described heat-conducting part 22, the lateral wall of heat-conducting part 22 is the circular arc matching with envelope inner wall substantially.Further to increase the contact area of heat-conducting part 22 and lamp housing, be more conducive to heat conduction, get to the object of very fast heat radiation.Cross section herein refers to the cross section perpendicular to heat-conducting part length direction, corresponding to the cross section shown in accompanying drawing 4.
this LED fluorescent tube comprises the end cap that is positioned at fluorescent tube length direction two ends, on described end cap, offer the through hole corresponding with described screw hole 25 and substrate 1 and penetrate the second through hole in lamp housing, the shape of the shape of the second through hole and substrate 1 matches, and screw passes through hole, screw hole 25 successively so that end cap is connected with heat conducting base 2.In locking end cap, screw hole 25 is stretched, and weak point 26 receives that the thrust that screw makes progress produces deformation, and the distance between wing limit 23 ends and body 21 is increased, be that the groove width that draw-in groove 24 removes at opening increases, substrate 1 can be aimed at easily and snap in a pair of draw-in groove 24 that opening is relative.
one or more in aluminium, copper, magnesium, zinc, aluminium alloy, copper alloy, magnesium alloy, kirsite of described heat conducting base are made.
the present invention adopts above structure, tool has the following advantages compared to existing technology: the end of establishing the draw-in groove of substrate at card offers the screw hole being connected, when screw penetrates after screw hole, the end of draw-in groove is softened, the groove width of draw-in groove opening part is greater than the thickness of substrate, can easily substrate be inserted in draw-in groove opening substrate card is located in the draw-in groove of heat conducting base, it is easy to assembling; Heat conducting base has the heat-conducting part being adjacent to mutually with lamp socket, has increased the contact area with lamp housing, and the heat that is more conducive to LED lamp pearl to produce conducts and is distributed to outside lamp housing; The heat-conducting part of LED substrate towards lamp housing center, extend and LED lamp pearl between two heat-conducting parts bottoms, it is lower that its light source position arranges, thus its light-emitting area is larger and from lamp socket more close to, radiating effect is better.
the lamp housing of addressing in the present invention and the length direction of body are perpendicular to the direction of paper in accompanying drawing 1.
above-described embodiment, for explanation technical conceive of the present invention and feature, is only a kind of preferred embodiment, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.The equivalence that all Spirit Essences according to the present invention are done changes or modifies, within all should being encompassed in protection scope of the present invention.
