Accompanying drawing explanation
Fig. 1 is example structure schematic diagram of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings with example
This utility model is described in further detail, but example is not as to restriction of the present utility model.
As it is shown in figure 1, embodiment of the present utility model includes light source module, radiator 5 and lamp screw base 6, light source module
Being arranged on the top of radiator 5, the lower section of radiator 5 is provided with lamp screw base 6, and light source module includes aluminium base 2, heat conductive silica gel
Sheet 3 and aluminum ring flange 4, aluminium base 2 is by heat-conducting silica gel sheet 3 and the fixing connection of aluminum ring flange 4, and radiator 5 uses metal and stone
Ink alkene modified plastics composite construction, the cross section of radiator 5 is sun fancy, and it utilizes plastic processing performance, and good feature is made
Semicircle micro structure, increases and air contact area, is beneficial to heat radiation.Radiator 5 is aluminum and Graphene modified plastics composite construction,
Radiator 5 uses aluminum and Graphene modified plastics as conducting-heat elements and thermal component respectively, and both pass through minute yardstick mechanical lock
Determine mechanism to combine, and played plastics plasticity much stronger than aluminum, and cost is less than the advantage of aluminum.Radiator 5 by roughening at
Reason metal surface injection mo(u)lding the most again, makes Graphene modified plastics be sufficient filling with the surface microscopic hole of aluminium base, works as graphite
Will bite the aluminium base with uneven matrix surface during alkene modified plastics cooling meat, thus form aluminum and Graphene changes
Property plastics micromechanical locking.Being provided with multiple LED lamp bead on aluminium base 2, LED lamp bead is evenly distributed on aluminium base 2.Also
Including shell 1, shell 1 is arranged on the top of light source module, and shell 1, light source module, radiator 5, lamp screw base 6 are by thin aluminum
Pipe 7 is fixing to be connected.
In the present embodiment, the mode that radiator 5 uses metal and Graphene modified plastics to be combined makes radiator；Radiator
5 use solid silicon films as interface Heat Conduction Material, it is to avoid solidification silica gel is non-dismountable and silicone grease is not suitable for amateur use
The defect that person smears voluntarily, designs readily replaceable light source module (LED lamp bead that aluminium base 2+ welds), as consumption simultaneously
Material.Light source module, heat-conducting silica gel sheet 3, radiator 5 are combined by simple mechanical system, it is not necessary to instrument is the most detachable, electric wire
Two ends respectively with solderable pressure line terminal, screw socket connect, light source module use Drive on board scheme, i.e. rectification
Part directly uses the mode of paster to be placed on aluminium base, and the wiring point of aluminium base is directly accessed LN.
In the present embodiment, the feature introduction of aluminum and heat-conducting plastic:
Aluminum heat conductivity is 201w/m k, and the heat-conducting plastic that with the addition of Graphene is about 5w/m k, the heat-transfer rate of aluminum
It is significantly faster than heat-conducting plastic.The specific heat capacity of aluminum is 0.88j/g DEG C, and density is 2.7g/cm3, every cm3Aluminum reduce by 1 DEG C about distribute
2.376j it is hot；The specific heat capacity of heat-conducting plastic is 1.5j/g DEG C, and density is 1.14g/cm3, every cm3Heat-conducting plastic reduce by 1 DEG C about
Distribute 1.71j heat.The heat radiation of radiator mainly by free convection, conforms to Newton's law, the object convection current of i.e. same profile
The speed of heat radiation is relevant with the temperature difference, and the biggest heat radiation of the temperature difference is the fastest.Convected air takes away same heat, and the temperature that plastics reduce is relatively
Few, the heat loss through convection speed being faster than aluminum can be maintained.Therefore, in conjunction with These characteristics, aluminum heat-transfer rate is faster than plastics, but heat radiation energy
Power lacks not as plastics.
This utility model, according to above-mentioned viewpoint, uses aluminum as conducting-heat elements, uses Graphene modified plastics as heat radiation
