Abstract
The utility model provides an LED (light-emitting diode) lamp structure dissipating heat easily and relates to the technical field of LED lighting. The structure specifically comprises lamp beads of LED lamps, an aluminum substrate and cooling fins, wherein the cooling fins are coated with a grapheme material, and the new material is characterized by having an ultrahigh heat-conductivity coefficient, so that problems of light attenuation and even overburning caused by rapid increase of the temperature of a chip due to the fact that high heat energy is produced by the chip instantaneously, transferred into the heat-conducting substrate and accumulated rapidly after the high-power LED lamps are electrified are effectively solved, and the heat dissipation problem of the LED lamps is solved fundamentally.
Description
Technical field
At the utility model, relate to LED field, particularly relate to the heat dissipation technology field of LED lamp.
Background technology
LED lamp be called as the 4th generation lighting source or green light source, there is the features such as energy-saving and environmental protection, life-span are long, be current state-of-the-art lighting engineering.But during the work of LED lamp, can produce a large amount of heats, make junction temperature increase, reduce the photon of chip transmitting, colour temperature raises simultaneously, has accelerated chip aging, has shortened the service life of lamp.Therefore solve particularly important that heat dissipation problem becomes.Graphene receives much concern as a kind of the thinnest novel two-dimensional nano material, it also has the heat conductivility of superelevation, the thermal conductivity factor of single-layer graphene can reach 5300W/mK, even there are some researches show its thermal conductivity factor up to 6600 W/ mK, excellent heat conductivility makes Graphene be called the hottest heat sink material.There is no at present Graphene is accelerated to its heat radiation for the fin of LED lamp.
The cooling system of existing LED lamp generally adopts fin to dispel the heat, and the LED lamp on market mainly adopts aluminum alloy heat sink, and surface majority is plane, and LED lamp directly contacts aluminium alloy heat radiator surface, carries out heat radiation work.Because LED lamp plate directly contacts aluminum alloy surface, the heat conductivility of aluminium alloy is general, and the heat that the long-term work of LED lamp produces cannot be derived in time, forms thermal resistance, has strengthened the light decay of LED lamp, has shortened the service life of LED lamp.
Summary of the invention
Technical problem to be solved in the utility model is the LED modulated structure that proposes a kind of easy heat radiation, accelerates the heat-transfer rate of LED lamp, has fundamentally solved the heat dissipation problem of LED lamp, effectively extends the service life of LED lamp on the basis that does not affect original shape.
The utility model solve the technical problem can be by realizing by the following technical solutions:
Propose a kind of LED modulated structure of easy heat radiation, specifically comprise lamp pearl, aluminium base and the fin of LED lamp, its fin is coated with grapheme material and has accelerated the heat energy derivation speed that the work of LED lamp produces, and has improved the heat conductivility of radiator.
The described fin surface that is coated with grapheme material comprises the fin surface contacting with aluminium base, better derives the heat on aluminium base.
Wherein the material of fin is white plastic-blasting aluminium flake, and when carrying out natural air heat loss through convection, heat loss through radiation ability is stronger.
The beneficial effects of the utility model are: graphene coated material on fin, the super good grapheme material of fin surface coated with thermally conductive performance simultaneously that contact with aluminium base, this mode can derive rapidly the heat gathering on LED chip, heat on fin is except utilizing cross-ventilation mode to dispel the heat, can also carry out heat loss through radiation because of white plastic-blasting aluminium flake material, effectively three large radiating modes are combined, fundamentally solved the heat dissipation problem of LED lamp.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, LED lamp 2, aluminium base 3, graphene film 4, fin.
The specific embodiment
Below in conjunction with accompanying drawing, further describe technical scheme of the present invention, but described in claimed scope is not limited to.
As figure, the LED modulated structure of a kind of easy heat radiation that the utility model provides, the lamp pearl, aluminium base and the fin that comprise LED lamp, the graphene coated material in surface of described fin, the fin surface contacting with aluminium base also applies graphene coated material simultaneously.During use, the heat that LED lamp chip produces is imported aluminium base into, because the effect of grapheme material passes on fin rapidly, then is dispersed in air by the effect of convection current and radiation.Improve the derivation speed of LED lamp generation heat, fundamentally effectively solved the heat dissipation problem of LED lamp, extended the service life of LED lamp.
