Description
Technical field
The present invention is relevant for a kind of lighting device, especially a kind of LED street lamp.
Background technology
Because light emitting diode (Light Emitting Diode, the used heat that is produced when LED) luminous has sizable negative effect to its life-span, and therefore, the street lamp of LED type is provided with the used heat that heat abstractor quickens loss LED mostly; On the other hand; Along with the increase of LED quantity and the exploitation of high-capacity LED; The heat that is produced during the running of LED light fixture is just progressively upwards soaring, therefore how for a kind of good structure of dispelling the heat of LED Design of Luminaires, has become one of important topic that the stakeholder studied of being engaged in this industry now.
Existing LED street lamp mainly is provided with the lamp socket body; Be provided with a plurality of LED in this lamp socket body; Then be equiped with heat abstractor on these LED, the setting of this heat abstractor can be cooling base and amplexiforms a plurality of radiating fins at this cooling base, to quicken to get rid of used heat by heat abstractor.
In the said structure, this heat abstractor amplexiforms above the LED of heating, because this heat abstractor adopts the mode of free convection to dispel the heat; Yet its louvre is arranged on the side or the end face of lampholder shell usually, and these LED bottom surfaces are not provided with louvre usually; After the cold air of outside gets into the lamp socket body; Must change direct of travel to take away the heat of LED, cause the gas flow paths of this lamp socket body interior not smooth, be unfavorable for that loss is extremely extraneous apace with hot gas; So radiating efficiency is not good, the high heat loss timely and effectively that is produced for the LED lamp.
Summary of the invention
One object of the present invention is to provide a kind of LED street lamp, its be on the upper and lower cover of lamp housing respectively correspondence offer a plurality of corresponding louvres, so as to quickening free convection speed, improve radiating efficiency.
In order to achieve the above object, the present invention is a kind of LED street lamp, comprises lamp housing, light emitting module, metal pedestal, two or more heat pipes and a plurality of radiating fin; Lamp housing comprises mutual cover and merges lower cover and the loam cake that is formed with accommodation space, is covered with perforate down, and be provided with first louvre in the side away from perforate; The corresponding first louvre place of loam cake is provided with second louvre; Light emitting module is contained in the accommodation space, and corresponding perforate configuration, and light emitting module comprises circuit board and is arranged on two or more LED lamps of circuit board one side; Metal pedestal comprises first plate body and second plate body that splices each other; And first plate body is the thermo-contact light emitting module, and each heat pipe comprises endotherm section and heat release section, and the endotherm section level is located between first plate body and second plate body; The heat release section horizontal-extending is at the side away from metal pedestal, and radiating fin is socketed on the heat release section of heat pipe with being arranged in parallel.
Another object of the present invention also is to provide a kind of LED street lamp, can the aspect projecting direction of adjustment LED street lamp.
In order to achieve the above object, the present invention provides a kind of LED street lamp, comprises:
Lamp housing; Comprise mutual cover and merge lower cover and the loam cake that is formed with accommodation space; Be covered with perforate under this; And be provided with two or more first louvres in a side away from this perforate, and this lower cover is provided with Connection Block in addition in a side of this first louvre, and this loam cake is to being provided with two or more second louvres in the first louvre place;
