Description
Technical field
The present invention relates to a kind of LED outdoor lighting lamp fitting, more particularly, relate to a kind of LED outdoor illumination radiator, belong to extraordinary LED outdoor illumination field.
Background technology
At present, high-power LED street lamp, Tunnel Lamp run into two large problems:
1, dust, greasy dirt problem.LED street lamp, Tunnel Lamp belong to outdoor lighting.Tunnel Lamp is operated in the environment of sealing; Take up a large amount of dusts when flue gas that automobile is discharged and operation, all can drop on the lamp radiator, and in the environment of this sealing, not have the cleaning of rainwater; Time has been grown; Certainly will cause the thick dust of deposition on the radiator, resistance shelves radiator contacts with air, and radiating efficiency is low.The LED Tunnel Lamp is operated in the subway, exposes to the open air on its surface of radiator outside and can overstock one deck greasy dirt and dust, is difficult to heat radiation; Radiator temperature raises; It is increasing that light decay becomes, and further shorten service life, and this point certainly will have a strong impact on the popularization of LED outdoor lighting.
2, accumulated snow problem.Along with the deterioration of global climate, rapid arctic weather often appears, at the weather that snows of subzero more than 20 degree; The LED street lamp can not be with snow melt, although LED also can generate heat when working because be cold light source; But because the too cold heat that sends of weather is dispersed in the air very soon, the temperature on the lamp body radiator can't rise to above zero all the time, so; Accumulated snow can't melt and whole lamp is encased, and causing does not have light on the road surface, be prone to cause traffic accident.
In the prior art, patent ZL200620116254.0 discloses a kind of radiator, it is characterized by a substrate, coats the ceramic layer of a convertible energy; Temperature rises, and ceramic layer can change into the square distribute heat that infrared ray penetrates heat radiation with the width of cloth with heat energy and reach the heat radiation purpose, still; Because its developed area of flat radiator is limited, heat dissipation capacity is just limited, therefore; Heat sinking function just is difficult to do greatly, has increased area of dissipation if radiator is made into to be made up of a lot of fins, but opposition each other between the radiating fin; Have only seldom infrared ray ejaculation radiator, most of infrared ray comes back reflective between fin, and radiating efficiency is low.
Summary of the invention
Technical problem to be solved by this invention provides a kind of good heat dissipation effect, can make snow melting, can prevent that again the dust greasy dirt from adhering on the radiator simultaneously, thereby prolongs LED light fixture a kind of LED outdoor illumination radiator in service life.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme:
A kind of LED outdoor illumination radiator; Comprise radiating bottom plate; Radiating bottom plate is provided with a plurality of heat radiation fins; Also comprise a protective cover with the transparent or infrared permeable of said radiator outside seal, be attached with on the described heat radiation fin and can heat energy be changed into ultrared coating that the both sides apportion of heat radiation fin is provided with the light guide.
A kind of LED outdoor illumination radiator; Comprise a vacuum cavity; The bottom seals of cavity has working medium; Be provided with a plurality of heat radiation gear pieces above the cavity, also comprise a protective cover with the transparent or infrared permeable of said radiator outside seal, be attached with on the described heat radiation gear piece and can heat energy be changed into ultrared coating.
Said smooth guide is provided with surrounding layer by rising near radiating fin to be arranged in order, sandwich layer, inner cladding, internal layer coupling body grating.
The bottom of said smooth guide is provided with mirror surface.
Said internal layer coupling body grating for directly on the optical fiber inner cladding decorations carve or mould molding becomes the isoceles triangle translot, surface finish is metal deposition or electroplate deielectric-coating and handle on its face again.
Said smooth guide is formed by pressing close to plated interface, printing opacity interface, covering, the sandwich layer that coating is arranged in order.
Surround circular helical form cavity between the said heat radiation fin, cavity inner wall is attached with ceramic coating.
Said coating is a ceramic coating.
Said protective cover is provided with the optical transmission window of inlaying the infrared permeable material.
The present invention is after adopting said structure; Can pass through ultrared protective cover radiator is sealed through being provided with; Its seal degree is invaded radiator for stoping the greasy dirt dust only fully; Thereby the coating through on the radiator changes into infrared ray with heat, through the light guide is set infrared ray is derived radiator.When the present invention uses; The heat that the work of LED lamp is produced is delivered to earlier on the base plate of radiator, then, and through the radiating fin distribute heat on the base plate; Through coating heat energy is changed into infrared ray; Infrared ray vertically passes the light guide and is mapped on the internal layer coupling body grating, and the isoceles triangle reflecting surface on the coupling body grating is coupled into the light guide of being made up of doubly clad optical fiber with light, and IR entering light sandwich layer in bond behind multiple internal reflection is propagated; An infrared ray part of propagating directly penetrates outside the radiator; A part injects in the radiator and after the reflecting surface reflection, penetrates radiator in the other direction, and it is aerial to pass the transparent outer cover directive, thereby reach heat is distributed to aerial purpose.Because of each heat radiation fin both sides all is provided with the light guide, the heat that the heat radiation fin absorbs can change into infrared ray with heat through the light guide and be mapped to outside the transparent outer cover through the guiding of light guide, accomplishes the heat radiation process, can realize better heat radiating effect.Further; Transparent outer cover is connected with vacuum heat-insulation or other heat insulation mode with radiator; Just can prevent accumulated snow, its operation principle is: because of not having between shell and the Inner heat sink or very little heat conduction, extraneous low temperature can not influence the temperature rise of Inner heat sink; Therefore radiator temperature just can send a large amount of infrared rays more than being elevated to 40 degree when LED works; Infrared ray passes transparent outer cover the accumulated snow on the shell is heated, and snow just can melt, thereby avoids causing the road surface not have the situation of light because of accumulated snow causes LED light to be blocked.On the other hand, transparent outer cover plays the effect of dust, and under the prerequisite that does not influence radiating effect, transparent outer cover can play the effect of protection radiator, avoiding radiator by accumulations such as dust, greasy dirts, thereby prolongs service life of radiator.
After the detailed description that combines advantages embodiment of the present invention, it is clearer that characteristics of the present invention and advantage will become.
