Abstract

The utility model discloses a light emitting diode (LED) street lamp, which comprises a lamp socket, a lampshade, a radiating body, LED luminous bodies, LED circuit boards and a plurality of LED luminous posts, wherein the LED luminous bodies and the LED circuit boards are arranged on the LED luminous posts; and each LED luminous body also comprises a radiating metal sheet. Both sides of each LED luminous post are provided with the LED luminous bodies, so that when the LED luminous bodies emit light, a light ray coverage range is up to 360 degrees and the lighting range is wide; the plurality of high-power LED luminous bodies emit light at the same time to enhance the lighting brightness; furthermore, the radiating metal sheets of the LED luminous posts can quickly transmit heat aggregated on the LED circuit boards to a radiating substrate; the radiating substrate and a radiating metal shell are welded to form a complete radiating body and quickly transmit the heat on the radiating substrate to the radiating metal shell; and the heat can be quickly radiated by the radiating metal shell.

Description

The LED street lamp
Technical field
The utility model relates to a kind of light fixture that is used for road lighting, and particularly a kind of illuminance is strong, LED streetlamp with favorable radiating effect.
Background technology
General street lamp adopts mercury vapor lamp, neon light, metal halide lamp etc. as light source more; The LED lamp is new in recent years a kind of technology of rising as road-light light-source; Have efficient, safety, energy-saving and environmental protection, distinct advantages such as the life-span is long, response speed is fast, colour rendering index height; Just progressively replace conventional road lamp, be widely used in city illumination.But all requirements to some extent of illumination brightness of LED street lamp and illumination zone; So the LED that adopts generally is a high-power LED; The heat that produces when high-power LED lamp is luminous is quite big; And the LED lamp to the heat radiation requirement than higher, therefore, how designing the LED street lamp that a brightness of illumination is strong, illumination zone is big, radiating effect is good is the technical problem that needs to be resolved hurrily in the industry.
Summary of the invention
The main purpose of the utility model provides a kind of LED street lamp, is intended to improve the brightness of illumination and the illumination zone of LED street lamp, accelerates the radiating rate of LED, prolongs the service life of LED street lamp.
The utility model proposes a kind of LED street lamp; This LED street lamp comprises lamp socket, lampshade, radiator, LED illuminator and led circuit plate; Also comprise some LED Column being luminous; Said LED illuminator and said led circuit plate are installed on the said LED Column being luminous, and said LED illuminator also comprises a heat dissipation metal plate.
Preferably, said LED Column being luminous comprises two blocks of led circuit plates, inserts and puts said heat dissipation metal plate between these two blocks of led circuit plates.
Preferably, said LED illuminator is fixed on the one side of said led circuit plate, and said LED illuminator is electrically connected with said led circuit plate, and said LED illuminator is at least one.
Preferably, said radiator comprises heat radiating metal shell and heat-radiating substrate, and said heat-radiating substrate is weldingly fixed on the top of said heat radiating metal shell.
Preferably, said LED Column being luminous is pegged graft and is fixed on the said heat-radiating substrate.
Preferably, said LED Column being luminous is at least one.
Preferably, be provided with the LED power circuit that is electrically connected with the led circuit plate in the said lamp socket.
The utility model comprise radiator that lamp socket, lampshade, heat radiating metal shell and heat-radiating substrate are formed and several by two packaged by some LED illuminators the led circuit plate and be interposed in the LED Column being luminous that two heat dissipation metal plates between the led circuit plate are formed.The LED illuminator all is equipped with in the both sides of LED Column being luminous, and when the LED illuminator was luminous, the light coverage can reach 360 degree, and illumination zone is big; The simultaneously luminous brightness of illumination that makes of a plurality of LED high-power light-emitting bodies strengthens; And the heat dissipation metal plate of LED Column being luminous can pass to heat-radiating substrate fast with the heat of assembling on the led circuit plate; Heat-radiating substrate and the welding of heat radiating metal shell form a complete radiator; With the heat transferred heat radiating metal shell on the heat-radiating substrate, distribute fast fast through the heat radiating metal shell.Therefore, the utlity model has the characteristics that brightness of illumination is strong, illumination zone is big, radiating rate is fast.
Description of drawings
Fig. 1 is the example structure sketch map of the utility model LED street lamp.
The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 1, an embodiment of the LED street lamp of the utility model is proposed, this LED street lamp comprises lamp socket 1, lampshade, radiator, LED illuminator 5 and led circuit plate 4, also comprises some LED Column being luminous.Be provided with the LED power circuit that is electrically connected with led circuit plate 4 in the said lamp socket 1.Said radiator comprises heat radiating metal shell 2 and heat-radiating substrate 3; Said heat-radiating substrate 3 is fixed on the top of said heat radiating metal shell 2 through the method for welding; Form a complete radiator; Make heat-radiating substrate 3 can heat be passed to heat radiating metal shell 2 fast, heat is passed by heat radiating metal shell 2.Said LED illuminator 5 is installed on the said LED Column being luminous with said led circuit plate 4, and said LED illuminator 5 also comprises a heat dissipation metal plate 6.Said lampshade covers on the outside of radiator and LED Column being luminous.
Said LED Column being luminous is pegged graft and is fixed on the said heat-radiating substrate 3; This LED Column being luminous comprises two blocks of led circuit plates 4; The front of two blocks of led circuit plates 4 all is equipped with at least one LED illuminator 5; Said LED illuminator 5 is electrically connected with said led circuit plate 4, and led circuit plate 4 is connected with power supply, makes electric current pass through led circuit plate 4 and is 5 power supplies of LED illuminator.The back side of two blocks of led circuit plates 4 is close to fixing each other, makes the both sides of LED Column being luminous that LED illuminator 5 all arranged, and when luminous, increases the light coverage; A plurality of LED illuminator 5 simultaneously luminous brightness of illuminations that make strengthen.Said heat dissipation metal plate 6 is interposed between the back side of these two blocks of led circuit plates 4; Can be with a large amount of heat transferred heat-radiating substrates 3 on the led circuit plate 4 that accumulate in of LED illuminator 5 luminous generations; Distributed apace through heat radiating metal shell 2 by heat-radiating substrate 3, radiating effect is good again, guarantees that temperature when LED illuminator 5 is luminous is in normal value; Reduce light decay, and prolong its service life.
