The characteristics that the LED road lighting lantern has that colourity is good, non-maintaining, the life-span is long the more important thing is more energy-conservationly than conventional road lamp, and the LED street lamp replaces conventional road lamp, is a kind of trend of the present whole society.

On the road of realizing the industrialization of LED street lamp, how to dispel the heat is a maximum difficult problem at present.If adopt common lamp body to add that fan dispels the heat, because fan itself relatively consumes energy and be, and the life-span of fan is very short, and LED road lamp energy-saving, advantage non-maintaining, that the life-span is long can not get fully playing, and make the LED street lamp be difficult to popularize.

And the general lamp housing that adopts common die casting or hardware stamping spare technology to make of LED street lamp, its die cost is very high, and every mold can only be produced the product of a profile specification.

The utility model content

The purpose of the utility model is to disclose the LED street lamp, has overcome heat radiation difficulty and the high shortcoming of lamp housing manufacturing cost.

For achieving the above object, the utility model adopts following technical scheme:

The LED street lamp comprises led light source assembly and the lamp housing that this led light source assembly is installed, and this lamp housing comprises by being provided with front and back, that be platy structure and alongst having the substrate that the section bar of same cross-sectional is processed at the diverse location place; The front of this substrate is equipped with the led light source assembly, and the back side of substrate is provided with several and plays radiating ribs thermolysis and that be platy structure position, the radiating ribs position that this radiating ribs position is its tapered structure in top.

Further, said radiating ribs position is uniformly distributed with the said back side that is arranged at said substrate, and extends along the length direction of said section bar.

The back side of said substrate is provided with several substrate aperture that is mutually symmetrical, and the side of this substrate aperture is provided with radiating groove, and this radiating groove is communicated with substrate aperture and said radiating ribs position.

The midway at the said back side of said substrate is provided with two hanger plates symmetrical, that the cross section is L-shaped and the length direction of the said section bar of court extends.So that power supply and fixing other parts are installed.

Further, the marginal position place of said substrate two relative sides in said front is provided with the side plate that is mutually symmetrical and extend along the length direction of said section bar respectively.

The positive at right angles structure of the inner surface of said side plate and said substrate.

The outside of said side plate be provided with even setting and that be parallel to each other several directly the point.

Further, said section bar is the section bar of aluminum or aluminum alloy.

Compared with prior art, the beneficial effect of the utility model:

1, adopt the structure of radiating ribs position, make the lamp body of LED street lamp have sufficient area of dissipation, the heat of generation directly dispels the heat in air in the time of can the LED street lamp work, energy-conserving and environment-protective and do not have the risk of maintenance.

2, substrate adopts section bar to process, and section bar can be cut into different length as required to process lamp housing, makes that the lamp housing of LED street lamp has versatility, has reduced production cost.

The utility model adopts above structure, and is simple in structure, have good performance of heat dissipation, and the lamp housing of the street lamp of different profile specifications can adopt the section bar of same specification to process, and has versatility, production efficiency is high and with low cost.
