Abstract

The utility model discloses a radiator of an LED street lamp. The radiator is characterized in that a shell used for installing an LED chip is included, the back side of the shell is provided with multiple strip-shaped cooling fins at intervals, a longitudinal air guide channel used for guiding air flow is formed between the back side of the shell and every two adjacent cooling fins, the cooling fins are provided with multiple air guide openings used for allowing air to pass and heat conductive columns used for quick heat conduction, besides, the corresponding air guide openings in the cooling fins are distributed in a straight line, and transverse air guide channels used for guiding air flow are formed in the cooling fins.

Description

A kind of LED street lamp heat radiator

Technical field

The utility model relates to a kind of street lamp, particularly a kind of LED street lamp heat radiator.

Background technology

Street lamp mostly in the past is traditional mercury bulb, and well-known, traditional mercury bulb service life is shorter, generally only have 3000 hours, very easily damage, change frequent, and power consumption is large, gradually cannot meet the green requirement of the energy-saving and emission-reduction of present society promotion.

Thereby, adopt at present LED street lamp to replace traditional street illumination lamp to become a kind of technological trend, as everyone knows, LED street lamp requires very strict on heat dispersion, too high temperature can cause the decay of LED street lamp luminous efficiency, and the working environment of LED street lamp very severe (being to be throughout the year always in open air windy and rainy and the high heat of high temperature), thereby its heat dissipation problem is particularly crucial, if cannot effectively dispel the heat to this class LED street lamp, can cause heat build-up, have a strong impact on luminous efficiency and service life, and have potential safety hazard.

And the radiator structure mode of present LED street lamp and installation heat dissipation element all do not reach good radiating effect, thereby also to improve it.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of LED street lamp heat radiator with great heat radiation effect.

The utility model solves the technical scheme that its technical problem adopts:

A kind of LED street lamp heat radiator, it is characterized in that: comprise the housing for LED chip is installed, back side of shell spacing is placed with the radiating fin of some strips, between back side of shell and two adjacent radiating fins, be formed for guiding longitudinal air-guiding aisle of Air Flow, and this radiating fin is provided with for the some air guide holes by air and for the heating column of quick conductive, and corresponding air guide hole draw up in line on each radiating fin is formed for guiding the horizontal air-guiding aisle of Air Flow in radiating fin.

Described radiating fin is provided with air diffluence pass, and described heating column is positioned at the bottom of the air diffluence pass corresponding with it.

Described heating column and radiating fin are integrally formed.

The beneficial effects of the utility model are: comprise with the housing that LED chip is installed, back side of shell spacing is placed with the radiating fin of some strips, between back side of shell and two adjacent radiating fins, be formed for guiding longitudinal air-guiding aisle of Air Flow, and this radiating fin is provided with for the some air guide holes by air and for the heating column of quick conductive, and on each radiating fin, corresponding air guide hole is arranged in a straight line, and is formed for guiding the horizontal air-guiding aisle of Air Flow in radiating fin.

Pass through said structure, the heat that LED chip distributes conducts rapidly on radiating fin and heating column by housing, distribute in the air by radiating fin, and air is by longitudinal air-guiding aisle and the laterally guiding of air-guiding aisle, from above-mentioned two passages, flow through, thereby distributing of accelerated heat reaches more excellent radiating effect, and longitudinally air-guiding aisle and horizontal air-guiding aisle are orthogonal, thereby can both play guiding function to the wind of all directions.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is schematic diagram of the present utility model;

Fig. 2 is the schematic diagram of the utility model other direction.

Detailed description of the invention

With reference to Fig. 1, Fig. 2, the utility model discloses a kind of LED street lamp heat radiator, comprise the housing 1 for LED chip is installed, housing 1 back side is a burnishing surface, housing 1 back side spacing is placed with the radiating fin 2 of some strips, between this burnishing surface and radiating fin 2, be formed for guiding longitudinal air-guiding aisle of Air Flow, thereby longitudinally air-guiding aisle is straight air channel, be convenient to Air Flow, and this radiating fin 2 is provided with for the some air guide holes 3 by air and for the heating column 4 of quick conductive, and corresponding air guide hole 3 draw up in lines on each radiating fin 2, in radiating fin 2, be formed for guiding the horizontal air-guiding aisle of Air Flow, the contact-making surface at the end face of heating column 4 and housing 1 back side is larger, thereby can conduct more heat, and can longitudinal air-guiding aisle not formed and be hindered.

As shown in the figure, radiating fin 2 is provided with air diffluence pass 5, described heating column 4 is positioned at the bottom of the air diffluence pass 5 corresponding with it, because of heating column 4 place's heats many, thereby need to form Air Flow by air diffluence pass 5, thereby the heat that this place is gathered is taken away fast, for heat conduction better, described heating column 4 is integrally formed with radiating fin 2.

A kind of LED street lamp heat radiator above the utility model embodiment being provided, be described in detail, applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof; , for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model meanwhile.
