Abstract

The utility model discloses a sectional material and a light-emitting diode (LED) street lamp. The sectional material comprises a base plate which is provided with a front side and a back side and is in a plate-shaped structure. The sectional material has identical sections on different positions along a length direction of the base plate. The back side of the base plate is provided with a plurality of heat radiating ribs, wherein the heat radiating ribs play a role of heat radiating and are in a plate-shaped structure, and top ends of the heat radiating ribs are connected together to form a baffle. By adopting the mentioned structure, the sectional material is simple in structure, and has good heat radiating performance, and reduces the frequency of maintenance and cleaning and other procedures. Street lamps of different shape specifications are made of a sectional material of the same specification, and therefore generality and production efficiency are high and cost is low.

Description

Section bar and light emitting diode road lamp

Technical field

The utility model relates to the luminaire field, is specifically related to section bar and LED (Light Emitting Diode, light emitting diode) street lamp.

Background technology

The characteristics that the LED road lighting lantern has that colourity is good, non-maintaining, the life-span is long be 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, so that the LED street lamp is difficult to popularize.

And the general lamp housing that adopts common die casting or hardware stamping spare technique 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 this utility model is to disclose section bar and LED street lamp, has overcome LED road lamp cooling difficulty and the high shortcoming of lamp housing manufacturing cost.

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

Section bar comprises being provided with substrate front and back and that be platy structure that this section bar has identical cross section along the length direction of substrate at the diverse location place; The back side of substrate is provided with several and plays radiating ribs thermolysis and that be platy structure position, the top of this radiating ribs position formation baffle plate that links together.

Further, the non-uniform described back side that is arranged at described substrate, described radiating ribs position, and extend along the length direction of substrate.

The back side of described 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 described radiating ribs position.

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

The invention also discloses the LED street lamp, comprise the led light source assembly, also comprise by described section bar intercepting lamp housing that form and that be used for installing this led light source assembly.

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

1, section bar adopts the structure of radiating ribs position, so that the lamp body of LED street lamp has sufficient area of dissipation, the heat that produces in the time of the LED street lamp can work directly dispels the heat in air, energy-conserving and environment-protective and without the risk of keeping in repair.

2, the top of radiating ribs position connects and composes the structure of baffle plate, prevents that the foreign material such as leaf from entering the radiating ribs position, reduces the frequency of maintenance and cleaning maintenance supervisor; The back side of baffle plate and substrate forms the die cavity of a both ends open, more is conducive to the ventilating convection heat radiation.

3, as required section bar is cut into different length to make lamp housing for the LED street lamp of different size, so that the lamp housing of LED street lamp has versatility, reduced production cost.

The utility model adopts above structure, simple in structure, have a good heat dispersion, reduce the frequency of maintenance and cleaning maintenance supervisor, and the lamp housing of the street lamp of different profile specifications can adopt the section bar of same specification to make, have versatility, production efficiency is high and with low cost.
