Description

A kind of LED street lamp
Technical field
The utility model belongs to the LED lighting field, is specifically related to a kind of LED street lamp.
Background technology
Most cities is all at the street lamp of promoting take LED as light source now, especially high-power heat-dissipation LED street lamp, the efficient white light-emitting diodes that its light source adopts low-voltage DC supply, synthesized by GaN based power type blue-ray LED and yellow fluorescent powder, have the particular advantages such as efficient, safety, energy-saving and environmental protection, life-span length, fast response time, colour rendering index height, but because high-power heat-dissipation LED street lamp caloric value when working is large, therefore need the larger heat abstractor of assembling to satisfy its heat radiation requirement.In order to satisfy the heat radiation requirement, some producer is divided into the up and down two halves with the LED light fixture, and the first half is radiating fin or thermal column, the Lower Half mounted LED lamp, be light-emitting window, some producer uses hot-pipe system, and the radiating fin of light fixture or thermal column and light-emitting window are in the light fixture Lower Half.Such light fixture, shortcoming is apparent, or after long-time the use, can make dust be accumulated in the root of radiating fin or thermal column, affect radiating effect, or be unfavorable for that cross-ventilation takes away heat, radiating rate is slow, and the not good meeting of radiating effect causes the LED street lamp lost of life.
Summary of the invention
The purpose of this utility model is for above-mentioned technical deficiency, but a kind of LED street lamp of quick heat radiating is provided, and it is simple in structure, thermal diffusivity good, effectively extends the LED street lamp life-span, is fit to city illumination and uses.
The technical solution of the utility model is as follows: a kind of LED street lamp, comprise radiator, lamp housing, aluminium base and LED lamp pearl, it is characterized in that: described radiator comprises thermal column and heat radiation top flat, thermal column and heat radiation top flat are equipped with louvre, thermal column and heat radiation top flat are metallic plate, thermal column is arranged on the lamp housing back side, the heat radiation top flat is installed on the top of thermal column, be provided with lamp plate in lamp housing, lamp plate is provided with a plurality of reflecting piece, reflecting piece evenly distributes on lamp plate, on the lamp plate of reflecting piece inboard, aluminium base is installed, and LED lamp pearl is installed on aluminium base.
Described louvre, the aperture is 0.1~0.3cm, is convenient to radiator heat-dissipation, has strengthened radiating effect, simultaneously because the aperture is less, dust or other foreign material are difficult to enter in radiator.
Described heat radiation top flat is curved and be provided with groove.
Described thermal column is provided with groove.
Described lamp housing side is provided with the electric connection socket.
The beneficial effects of the utility model are:
1, heat dispersion is good.LED lamp pearl, aluminium base and radiator be equipped being combined into one mutually, radiator comprises heat radiation top flat and thermal column, heat radiation top flat and thermal column are equipped with the groove with louvre, heat radiation top flat and thermal column are metallic plate, heat not only can vertically dispel the heat between thermal column, and can carry out heatsink transverse by the hole, and the capacity of heat transmission is strong, and radiating rate is fast;
2, effectively extend the service life of LED street lamp.The heat radiation top flat is provided with aperture, the top flat heat radiation but also prevent that dust or other foreign material from directly entering in radiator, increases the service life of not only being convenient to dispel the heat;
3, simple and practical.The utility model adopts modularized design, and easy accessibility can increase and decrease aluminium base according to the actual needs in lamp housing, and also can outsidely connect increases the lamp body number, simple and practical.
