The efficient heat-dissipation LED illuminating lamp disclosed by the utility model has the advantages that the structure is simple, the heat-dissipation efficiency is high, and during working, the temperature balance point is low, so that the effects of reducing the light attenuation of an LED light source, prolonging the service life of the LED lamp and ensuring the normal light-emitting color can be achieved.
Description
Technical field
The utility model belongs to the technical field of LED illuminating lamp, relates in particular to a kind of high-efficiency heat radiating LED illuminating lamp.
Background technology
The LED illuminating lamp is the new type light source of a kind of efficient, energy-saving and environmental protection, safety, has progressively replaced conventional light source such as traditional tengsten lamp, fluorescent lamp.But in led chip when work,, 20～30% the power of only having an appointment is converted into luminous energy, and all the other power of 70～80% are converted into heat energy; The degree of heat is quite high; Therefore these heats are effectively distributed rapidly, otherwise can influence LED illuminating lamp operate as normal, the aggravation light decay; Reduction of service life, also possibly make the glow color of LED illuminating lamp undesired.
The common structure of existing LED illuminating lamp is to be installed in chip on the plastic base, and plastic base is installed on the aluminium alloy thermal component again.Not enough below said structure exists: (1), thermal component mainly contain radiation and two kinds of radiating modes of convection current, but the radianting capacity of aluminium alloy is lower, and it is infrared rate just 0.5 when 100 spend, and when the normal temperature that is lower than 100 ℃ emissivity far below 0.5.This means that existing LED illuminating lamp is below 100 ℃ the time, radiation efficiency is low, and the heat loss through convection degree is limited, so its heat that sends can not dispel the heat quickly and effectively.Only behind the high temperature that reaches the uniform temperature value; Existing LED illuminating lamp just can reach the balance of heat production speed and radiating rate; This Temperature numerical that reaches balance just is called " temperature equalization point "; In the course of the work, the temperature value of LED illuminating lamp thermal component just remains near this temperature equalization point; Obviously, radiating rate is unhappy during owing to low temperature, and the temperature equalization point of existing LED illuminating lamp is higher, and the temperature when making whole LED illuminating lamp work is high, and light decay is more violent, and has shortened the service life of LED illuminating lamp; (2), plastic base and aluminium alloy thermal component package assembly be complicated, both can't be integrally formed, there is air gap in interface between the two, this air gap position thermal resistance is big, this also is unfavorable for quick heat radiating; (3), thermal component weight is bigger, LED illuminating lamp weight is bigger thereupon, when the street lamp of installing as cantilever when the LED illuminating lamp used, its support force of encorbelmenting was big.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned shortcoming and a kind of high-efficiency heat radiating LED illuminating lamp is provided, it simple in structure, and radiating efficiency is high, and the temperature equalization point during work is low.
Its purpose can realize by following scheme: this high-efficiency heat radiating LED illuminating lamp comprises plastic base; Chip is installed on the plastic base; The place ahead of plastic base is equipped with translucent cover; Its main feature is, at the rear of plastic base plastic stent is installed, and evenly fills in the plastic stent and is distributed with CNT.
The elongated semicircle shape of said plastic stent, the elongated semicircle shape of said translucent cover, it is cylindric to form strip after plastic stent and the translucent cover amalgamation.Above-mentioned plastic stent had both played thermolysis, can be used as tube stand again simultaneously, and this version is suitable for the LED fluorescent tube.
Plastic stent and plastic base injection moulding become one, and the plastic base surface scribbles an insulating barrier.
The utlity model has following advantage and effect:
1, because CNT just has very high infrared rate (for example CNT infrared rate when 20 spend surpasses 0.9) when normal temperature; The utility model is evenly filled in plastic stent and is distributed with CNT; Can be with the heat of LED lamp efficiently to external radiation, and near or just can efficient quick heat radiating during a little more than normal temperature, when the lower temperature value, just can realize the balance of radiating rate and heat production speed; Therefore compare with traditional structure; The temperature equalization point of the utility model LED illuminating lamp is lower, and the temperature the during work of whole LED illuminating lamp is low, reaches to reduce the led light source light decay, prolong LED lamp service life, guarantee the normal effect of glow color.
2, plastic stent and plastic base can be integrally formed, and help simplified structure, eliminate the air gap between plastic base and the plastic stent, reduce thermal resistance on the heat dissipation path, more improve radiating rate.
3, owing to can avoid the use of heavier aluminium alloy heat radiator, make the weight saving of whole LED illuminating lamp, help follow-up installation, alleviate the stressed of cantilever street lamp bracket as the cantilever street lamp.
