The specific embodiment
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Referring to figs. 1 through Fig. 5, an embodiment of a kind of LED street lamp of the present invention is proposed, comprise mounting bracket 200, be located at the lamp stand head 100 of mounting bracket 200 ends, along mounting bracket 200, be connected with from the bottom to top lower end housing, radiator 500, upper end housing 600 in turn.Also comprise the LED light source structure of being close on described radiator 500 fronts, be covered on the structural diffuser 800 of LED light source, LED light source structure comprises the circuit board 700 be close on radiator 500 fronts, is evenly laid in the LED lamp pearl 701 on circuit board 700, and diffuser 800 is provided with air-vent 801.Lower end clamshell is located at outside lamp stand head 100, between lower end housing lower end and lamp stand head 100, be provided with the heat radiation space 101 that passes straight through to radiator 500, lower end housing comprises that shell face is provided with the front end housing 300 of some the first heat radiation through holes 301, the rear end housing 400 being connected by screw with front end housing 300, radiator 500 fronts are provided with some heat radiation stripeds 501, radiator 500 back sides are provided with and are the radiating fins 503 that many row's multiple rows distribute, and each is arranged and between each row radiating fin 503, is provided with the 3rd heat radiation through hole 502.Upper end housing 600 is connected by blocking the mode of inserting with mounting bracket 200, and upper end housing 600 inside are set to hollow cavity, and hollow cavity top is provided with some the second heat radiation through holes 601.
Lower end clamshell is located at outside lamp stand head 100, between lower end housing lower end and lamp stand head 100, be provided with the heat radiation space 101 that passes straight through to radiator 500, upper end housing 600 is connected by blocking the mode of inserting with mounting bracket 200, upper end housing 600 inside are set to hollow cavity, and hollow cavity top is provided with some the second heat radiation through holes 601.By the ingenious combination of heat radiation space 101 and the second heat radiation through hole 601, clearly find out LED street lamp from the bottom to top air can circulate, by airflow, carry out heat exchange, can reach good radiating effect, heat dishoarding, effectively guarantee the long-term normal work of LED light source structure, extend the service life of LED light source assembly.
Simultaneously, the front end housing 300 of lower end housing is provided with the first heat radiation through hole 301, the drive unit 900 being electrically connected to LED light source structure is placed in lower end housing and is corresponding adaptive with the first heat radiation through hole 301 position of opening, and 503 of radiator 500 backside heat fins are provided with the 3rd through hole 502 that dispels the heat.As can be seen here, air-flow is longitudinally circulation not only, and laterally also can carry out swimmingly heat exchange, whole housing ventilation and heat, and extraneous dust can not stopped and accumulate in lamp housing by wind-force effect.The heat producing during drive unit 900 work, not only can dispel the heat by heat radiation space 101, can also directly be dispersed in extraneous air immediately through the first heat radiation through hole 301, has effectively protected the normal work of drive unit 900, extends its service life.The 3rd heat radiation through hole 502 can also play a role in the drainage; in the time of the rainy day; rainwater can directly be discharged into nature through the 3rd heat radiation through hole 502; the a small amount of dust gathering on radiating fin 503 is also cleaned out together simultaneously; make 503 of the radiating fins at radiator 500 back sides not gather rainwater and dust; and the circulation of air is, the discharge of rainwater makes radiator 500 can not gather dust, has effectively protected its radiating effect.LED street lamp of the present invention, reaches extraordinary radiating effect by design own, unlike conventional road lamp, take radiation as main radiating mode, and radiating effect is not good.When long-time use, affected by the external environments such as dust, dust is bedded on street lamp, radiation is had a strong impact on, radiating effect can be worse and worse, thus the heat that LED work is produced constantly hoard, high temperature causes LED light source assembly life-span to fall sharply.
Radiator 500 fronts are provided with some heat radiation stripeds 501, and radiator 500 back sides are provided with and are the radiating fin 503 that many row's multiple rows distribute.The heat producing while being close to the LED light source arrangement works on radiator 500 fronts is delivered to rapidly on radiator 500, the design of heat radiation striped 501 and radiating fin 503, greatly increase the contact area of radiating surface and extraneous air, in time dissipation of heat is gone out rapidly, further guarantee the long-term normal work of LED light source structure.
Mounting bracket 200, lamp stand head 100, radiator 500 are made by heat-conducting metal, and heat-conducting metal is selected iron, aluminium or copper.Lower end housing and upper end housing 600 are made by heat-conducting metal or plastics.Heat-conducting metal has good heat-conducting effect, the heat dishoarding that LED street lamp when work produces, and good heat dissipation, heat conduction are fast.Between lower end housing, radiator 500 and upper end housing 600, be provided with gap, can make LED street lamp work package 360 degree without dead angle be communicated with extraneous air, further promote heat exchange, through hole and gap can make rainwater and dust not accumulate on connecting portion simultaneously, reach the effect of dustproof and waterproof.
Diffuser 800 is made by glass or plastics, and diffuser 800 is connected by screw mode with radiator 500 and is connected, and in junction, is provided with silica gel ring.Silica gel ring plays the effect of water proof and dust proof effectively, has greatly improved the IP value of LED street lamp of the present invention.Silica gel ring both can make diffuser 800 closely be connected with radiator 500, also can prevent that screw from damaging diffuser 800 by pressure, prevented that in use procedure, screw loosening causes destroying LED light source structure into water simultaneously.Diffuser 800 is provided with air-vent 801, and under guaranteeing the condition of soaking in moisture is not, the heat that 701 work of LED lamp pearl are produced is discharged in extraneous air, thereby reduces the temperature in diffuser 800, effectively guarantees the long-term normal work of LED lamp pearl 701.LED light source with the mode of point light source light-emitting cause that light intensity distributions is inhomogeneous, light emitting region is narrow, LED light source exiting surface is little, light intensity distributions concentrations and make ground occur the phenomenon of hot spot, the Lens Design of LED street lamp diffuser 800 of the present invention, when irradiating out, light reflects, thereby make light more even, lighting angle more comprehensively, illumination effect is better, and illumination more meets the specification requirement of road lighting.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure transformation that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
