In order to further increase the heat dissipation performance of the fluorescent tube, for example, the heat dissipating housing, the lamp plate, the heat-dissipating cylinder And the radiating piece is all made of NEW TYPE OF COMPOSITE heat dissipation alloy and is prepared, the NEW TYPE OF COMPOSITE heat dissipation alloy includes being sequentially overlapped to set Heat-sink shell, heat-conducting layer and the heat dissipating layer set；For another example, the heat-sink shell, the heat-conducting layer it is identical with the material of the heat dissipating layer or The different setting of person；For another example, the LED sub-light sources and OLED sub-light sources are set to the heat-sink shell；For another example, the heat-sink shell, institute The heat-conductive characteristic for stating heat-conducting layer and the heat dissipating layer successively decreases successively, forms heat-conductive characteristic gradient, to advanced optimize The heat dissipation path of the NEW TYPE OF COMPOSITE heat dissipation alloy, greatly improve the heat dissipating housing, the lamp plate, the heat-dissipating cylinder and The heat dissipation performance of the radiating piece, and then improve the heat dissipation performance of the fluorescent tube so, it is possible to meet big described of calorific value The radiating requirements of fluorescent tube.

For example, the fluorescent tube of an embodiment of the present invention, wherein the heat-sink shell of the NEW TYPE OF COMPOSITE heat dissipation alloy, Include each component of following mass parts：

90 parts~92 parts of copper, 2 parts~4.5 parts of aluminium, 1 part~2.5 parts of magnesium, 0.5 part~0.8 part of nickel, 0.1 part~0.3 part of iron, 1.5 parts~4.5 parts of vanadium, 0.1 part~0.4 part of manganese, 0.5 part~0.8 part of titanium, 0.5 part~0.8 part of chromium, 0.5 part~0.8 part of vanadium, silicon 0.8 part~15 parts and 0.5 part~2 parts graphenes.

First, what the copper (Cu) that above-mentioned heat-sink shell contains 90 parts~92 parts can make heat-sink shell has preferable heat absorption energy. When the mass parts of copper be 90 parts~92 parts when, the coefficient of heat conduction of heat-sink shell can reach 365W/mK or more, can rapidly by The heat that LED sub-light sources and OLED sub-light sources generate siphons away, and then is dispersed in the structure of heat-sink shell entirety with making even heat, To prevent heat from being accumulated on the contact position between LED sub-light sources and OLED sub-light sources and heat-sink shell, cause hot-spot existing The generation of elephant.Moreover, the density of heat-sink shell is less than the density of fine copper, it can effectively mitigate the weight of heat-sink shell in this way, it is more sharp It is manufactured in installation, while also greatly reducing cost.Wherein, the definition of the coefficient of heat conduction is：Per unit length, per K, can be with The energy of how many W, unit W/mK are transmitted, wherein " W " refers to thermal power unit, " m " represents length unit rice, and " K " is absolute Temperature unit, the numerical value is bigger to illustrate that heat absorption capacity is better.In addition, by adding 0.5 part~2 parts of graphene, it can be effective Ground improves its coefficient of heat conduction, and then improves the heat absorption capacity of the heat-sink shell.

Secondly, heat-sink shell contain mass parts be 2 parts~4.5 parts aluminium, 1 part~2.5 parts of magnesium, 0.5 part~0.8 part of nickel, 0.1 part~0.3 part of iron, 1.5 parts~4.5 parts of vanadium, 0.1 part~0.4 part of manganese, 0.5 part~0.8 part of titanium, 0.5 part~ 0.8 part of chromium and 0.5 part~0.8 part of vanadium vanadium.Relative to fine copper material, the ductility of heat-sink shell, toughness, intensity with And high temperature resistance is improved significantly, and not easy-sintering；In this way, LED sub-light sources and OLED sub-light sources are installed to suction When on thermosphere, so that it may be damaged, also, had to heat-sink shell with the high temperature for preventing LED sub-light sources and OLED sub-light sources from generating Preferable ductility, toughness and intensity are also possible to prevent heat-sink shell when installing the LED sub-light sources and OLED sub-light sources Caused to deform by excessive stresses.Wherein, heat-sink shell contains the nickel (Ni) that mass parts are 0.5 part~0.8 part, can improve suction The high temperature resistance of thermosphere.For another example, heat-sink shell, which contains the vanadium (V) that mass parts are 1.5 parts~4.5 parts, can inhibit heat-sink shell crystal grain It grows up, obtains more uniform tiny grain structure, to reduce the brittleness of heat-sink shell, improve the mechanical property of heat-sink shell entirety, with Improve toughness and intensity.For another example, heat-sink shell contains the titanium (Ti) that mass parts are 0.5 part~0.8 part, can make the crystalline substance of heat-sink shell Grain miniaturization, to improve the ductility of heat-sink shell.

Finally, heat-sink shell further includes the silicon (Si) that mass parts are 0.8 part~15 parts, when heat-sink shell contains suitable silicon, The hardness and abrasion resistance of heat-sink shell can be effectively promoted under the premise of not influencing heat-sink shell heat absorption capacity.But through repeatedly managing It finds by analysis and experiment evidence, when the quality of silicon in heat-sink shell is too many, such as mass percent is more than 15 parts or more, can make The appearance of heat-sink shell is distributed black particles, and ductility reduces, and is unfavorable for the production molding of heat-sink shell.

For example, the fluorescent tube of an embodiment of the present invention, wherein the heat-conducting layer of the NEW TYPE OF COMPOSITE heat dissipation alloy, Include each component of following mass parts：

60 parts~65 parts of copper, 55 parts~60 parts of aluminium, 0.8 part~1.2 parts of magnesium, 0.2 part~0.5 part of manganese, titanium 0.05 part~0.3 Part, 0.05 part~0.1 part of chromium, 0.05 part~0.3 part of vanadium, 0.3 part~0.5 part of silicon and 0.1 part~0.3 part of graphene.

First, it is 60 parts~65 parts of copper and 55 parts~60 parts of aluminium that above-mentioned heat-conducting layer, which contains mass parts, can be made The coefficient of heat conduction of heat-conducting layer is maintained at 320W/mK~345W/mK, described in ensureing that heat-conducting layer can will absorb by heat-sink shell The heat that LED sub-light sources and OLED sub-light sources generate is quickly transmitted to heat dissipating layer, and then prevents heat from being accumulated on heat-conducting layer, Hot-spot phenomenon is caused to generate.Compared with the existing technology, merely use price costly and the larger copper of quality, it is above-mentioned to lead Thermosphere can not only ensure that quickly the heat transfer by heat-sink shell was to heat dissipating layer, but also have lighter weight, be easily installed casting, price Less expensive advantage.Meanwhile compared with the existing technology, the aluminium alloy for merely using heat dissipation effect poor, above-mentioned heat-conducting layer tool There is more preferably heat transfer property.

Next can greatly improve the heat conductivility of the heat-conducting layer by 0.1 part~0.3 part of graphene of addition, Preferably by the heat transfer passed over from heat-sink shell to heat dissipating layer.

Finally, it is 0.8 part~1.2 parts of magnesium, 0.2 part~0.5 part of manganese, 0.05 part~0.3 that heat-conducting layer, which contains mass parts, The titanium, 0.05 part~0.1 part of chromium, 0.05 part~0.3 part of vanadium and 0.3 part~0.5 part of silicon of part, so as to improve heat-conducting layer Mechanical performance and high temperature resistance, e.g., mechanical performance includes but is not limited to yield strength, tensile strength.For example, heat-conducting layer The magnesium for being 0.8 part~1.2 parts containing mass parts, can assign heat-conducting layer yield strength and tensile strength to a certain extent, by In the fabrication process in NEW TYPE OF COMPOSITE heat dissipation alloy, it needs heat-sink shell, heat-conducting layer and heat dissipating layer entirety punching press being integrally formed, This just needs heat dissipating layer to have stronger yield strength, to prevent heat dissipating layer from being generated in process by favourable opposition compression Non-reversible deformation, and then ensure the proper heat reduction performance of NEW TYPE OF COMPOSITE heat dissipation alloy.When the relative mass of magnesium is too low, e.g., matter When measuring part less than 0.8 part, it cannot substantially ensure that the yield strength of heat-conducting layer is met the requirements, however, the relative mass when magnesium is excessively high When, such as when mass parts are more than 1.2 parts, and can make the ductility and heat conductivility dramatic decrease of heat-conducting layer.For example, heat conduction The iron that layer is 0.2 part~0.8 part containing mass parts, can assign the higher high temperature resistance of heat-conducting layer and high temperature resistant mechanicalness Can, the processing for being conducive to heat-conducting layer is cast.

For example, the fluorescent tube of an embodiment of the present invention, wherein the heat dissipating layer of the NEW TYPE OF COMPOSITE heat dissipation alloy, Include each component of following mass parts：

88 parts~93 parts of aluminium, 5.5 parts~10.5 parts of silicon, 0.3 part~0.7 part of magnesium, 0.05 part~0.3 part of copper, 0.2 part of iron~ 0.8 part, 0.2 part~0.5 part of manganese, 0.05 part~0.3 part of titanium, 0.05 part~0.1 part of chromium, 0.05 part~0.3 part of vanadium and 5 parts~15 Part graphene.

First, above-mentioned heat dissipating layer contains the aluminium that mass parts are 88 parts~93 parts, can make the coefficient of heat conduction of heat dissipating layer It is maintained at 200W/mK~220W/mK, when the heat that LED sub-light sources and OLED sub-light sources generate passes through heat-sink shell and heat-conducting layer After part is radiated, when remaining heat passes to heat dissipating layer by heat-conducting layer again, heat dissipating layer may insure these remaining heat Amount by consistent scatters away, and then prevents heat from being accumulated on heat dissipating layer, causes hot-spot phenomenon.

Next can effectively improve the heat dissipation performance of the heat dissipating layer by 5 parts~15 parts of graphene of addition, into And it will can be rapidly lost in extraneous air dielectric from the heat that the heat-conducting layer is transmitted to.
