Description
Technical field
The present invention relates to a kind of integral heat dissipation LED road lamp.
Background technology
The energy consumption of lighting field accounts for 20% of whole electric energy, and that common illuminating lamp only has 30% electric energy to be used for is luminous, and all the other have changed into heat energy and have distributed to the external world.The heat that LED produces during because of its work is less, and luminous efficiency is higher, is regarded as cold light source.The LED street lamp is made up of substrate, lens and the cooling system etc. of band LED, compares with traditional incandescent lamp, fluorescent lamp, and its electric energy can reach more than 90%.Since it is born,, more and more be subjected to the attention of countries in the world with its efficient low-consume, energy-conserving and environment-protective, long characteristics of life-span.China is used for the electric power of street lighting present every year near 2,500 hundred million degree, and wherein if can have 1/3 to adopt the LED street lighting, annual just can the economize on electricity about 80,000,000,000 degree is equivalent to the annual electricity generating capacity in power station, Three Gorges basically.
Though LED is regarded as cold light source, still can produce certain heat during work.The operating temperature of LED generally should be less than 50 ℃.There is data to show that when the operating temperature of LED reaches 55 ℃, its life-span will reduce half.The heat radiation system of present LED street lamp is imperfection very, has become it and has applied stumbling-block in the process, and is even more serious for middle this kind of high-capacity LED street lamp situation.Therefore heat dissipation technology has become one of main direction of studying of person skilled.
Street lamp is in outdoor environment for a long time, requires waterproof and dustproof, protection against insect on the structure, and its lampshade must be the cavity of a sealing.The LED of LED street lamp will work in the environment of sealing equally, and this just means that it can't can only outwards dispel the heat by lampshade by cross-ventilation directly to external world's heat radiation.For this reason, some technical staff is provided with fin at substrate back, and the heat that LED is sent in time is dispersed in the air by fin.Limited but the lampshade inner space is sealed, can't form effective convection current, the heat transfer coefficient of air is low again, so this LED street lamp is only very fast to the heat radiation of fin from LED, and very slow from fin to external world's heat radiation, can't adapt to the long-term work requirement of street lamp.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, the integral heat dissipation LED road lamp that provide a kind of good heat dissipation effect, effectively increases the service life.
The technical solution adopted in the present invention is: the present invention includes the metal back cover, substrate, the printing opacity front shroud, several LED, several described LED are installed on the described substrate, and in described substrate is arranged at the chamber that described back cover and described front shroud surround, be provided with radiator between described substrate and the described back cover, described radiator comprises the heat radiation backboard, several heat conduction muscle, have several notches on the described heat radiation backboard, described notch is divided into several folding faces with described heat radiation backboard, described folding face only depends on the part to interconnect, described heat radiation backboard closely contacts connection mutually with the inner surface of described back cover and the shape of the two is suitable, on the described heat conduction muscle, the bottom respectively with described heat radiation backboard, described substrate is connected.
Several described heat conduction muscle are parallel to each other, form heat-dissipating space between the adjacent described heat conduction muscle.
The bottom of described heat conduction muscle is provided with lower hem, and closely contact connection and the shape of the two are suitable mutually with described substrate for described lower hem.
The top of described heat conduction muscle is provided with upper hem, the inner surface of described upper hem and described heat radiation backboard be fixedly connected and the shape of the two suitable.
The invention has the beneficial effects as follows: owing to be provided with radiator between substrate of the present invention and the described back cover, described radiator comprises the heat radiation backboard, several heat conduction muscle, described heat radiation backboard closely contacts connection mutually with the inner surface of described back cover and the shape of the two is suitable, on the described heat conduction muscle, the bottom respectively with described heat radiation backboard, described substrate is connected, such structure make heat that street lamp when work LED produces through described substrate successively by described heat conduction muscle, described heat radiation backboard conducts described back cover, and be diffused in the external environment by the described back cover of metal manufacturing, LED is under the suitable operating temperature state all the time, the life-span reduction of having avoided LED at high temperature to work for a long time causing, so good heat dissipation effect of the present invention can effectively increase the service life;
Because several described heat conduction muscle of the present invention are parallel to each other, form heat-dissipating space between the adjacent described heat conduction muscle, this structure makes that air is mobile comparatively smooth and easy in the chamber that described back cover and described front shroud surround, and helps to dispel the heat, so radiating effect of the present invention is better;
Because the bottom of heat conduction muscle of the present invention is provided with lower hem, closely contact connection and the shape of the two are suitable mutually with described substrate for described lower hem, the top of described heat conduction muscle is provided with upper hem, the inner surface of described upper hem and described heat radiation backboard be fixedly connected and the shape of the two suitable, this structure makes that the contact area of described heat conduction muscle and described substrate and described heat radiation backboard is big, good effect of heat exchange is so radiating effect of the present invention is better;
Owing to have several notches on the heat radiation backboard of the present invention, described notch is divided into several folding faces with described heat radiation backboard, described folding face only depends on the part to interconnect, like this, be convenient to the punching press of described heat radiation backboard on the one hand, make, the inner surface configuration of described heat radiation backboard and described back cover is coincide as far as possible; On the other hand, the described heat radiation backboard pressurized in back is installed, the adaptability distortion can take place in described folding face, eliminates the fine clearance between described heat radiation backboard and the described back cover, more helps heat radiation, so radiating effect of the present invention is better.
