Technical field
The present invention relates to lighting field, particularly a kind of outdoor use LED lamp.
Background technology
LED (Light Emitting Diode), i.e. semi-conductor electricity light source, light emitting diode, also referred to as semiconductor lamp, be
A kind of electric light source without filament, is directly converted into luminous energy electric energy.
LED has long-life, specular removal, end power consumption, anti-vibration, response time advantage short, free of contamination, as one
Energy-conservation point source product, its application is more and more extensive；Along with the progress of technology, its color change is more and more abundanter so that it is
Can be used not only as ornamental light source, it is also possible to be used for illuminating.Existing illuminating LED lamp, general power is relatively low, it is adaptable to space
Less illumination place, for the place that the spaces such as road, bridge, stadiums, harbour are bigger, then needs to use greater power
LED, illumination needs could be met, along with the caloric value of the increase of power, LED and driver thereof is also big, the light efficiency of LED
Can decline along with the rising of temperature, service life also can shorten because of the rising of temperature, and therefore, heat dissipation problem is to solve big merit
One importance of rate LED popularization and application.
At present, the heat radiation of LED radiator to be relied on.But traditional radiator is typically all the cylinder closed
Shape, so make radiator inner air cannot in time and outside air circulation, just cause radiating efficiency low, cause LED light
Source and power source temperature are too high, thus have had influence on light efficiency and the life-span of LED.Although now with radiator also have louvre,
But being to LED dust and moisture, its louvre is less, causing the heat radiation problem such as the most unobstructed, this also will have influence on LED
Service life.
Based on this, it is necessary to LED lamp is transformed, it is provided that a kind of radiating efficiency is high, the LED lamp of dust and moisture.
Summary of the invention
In order to overcome the defect of prior art, the present invention provides a kind of outdoor use LED lamp with great heat radiation effect.
A kind of outdoor use LED lamp of the present invention, including housing and luminescence unit, described luminescence unit includes multiple heat radiation
Device and installation substrate on a heat sink, described substrate is packaged with LED lamp bead；
Described housing includes an arc-shaped cover and the mounting seat being arranged in arc-shaped cover, and described mounting seat is grid-like, described
Radiator is fixed in described mounting seat；
Described radiator includes radiator body, multiple louvres being arranged on described radiator body and with described
The deformations that radiator body connects, described radiator body is hollow-core construction, and the inwall of radiator body has for pacifying
The raised line of dress substrate, described deformations matches with described louvre, and described deformations is made up of shape memory alloy material, institute
State deformations for producing to the Bending Deformation away from described louvre direction when it is heated and reaches preset temperature value.
Specifically, described substrate has the groove being fixed with the raised line on described radiator.
Preferably, described deformations is arranged on the edge of louvre.
Preferably, described radiator body outer wall connects multiple radiating fin.
Preferably, described louvre is strip.
Preferably, described radiator body is circular tube shaped, and described louvre arranges along described radiator body circumferencial direction.
The invention has the beneficial effects as follows:
The LED lamp of the present invention has that compact conformation, production cost be low, dust and moisture, good heat dissipation effect, illumination are stable,
Service life length advantage.
(1) present invention utilizes shape memory alloy material to have the feature of shape memory, and design can cover the shape of louvre
Change portion, at normal temperatures, louvre is closed by deformations, makes louvre be in the state of closing, thus can avoid dust, steam etc.
Enter in radiator, play the effect of dust and moisture.In lighting process, LED is dispelled the heat, and the temperature of deformations can gradually rise,
When deformations be heated reach preset temperature after can produce to the Bending Deformation away from louvre direction, make louvre open, thus
Promote air circulation, improve radiating efficiency.
(2) the multi-disc radiating fin being arranged on radiator body outer wall can provide bigger area of dissipation to help radiator
Heat radiation, improves heat transfer efficiency.The mounting seat of radiator is set to grid-like, the flowing of shell inner cavity air can be beneficial to, be beneficial to dissipate
Heat.
(3) present invention uses arc-shaped cover outside street lamp, will not hydrops laying dust.
Accompanying drawing explanation
In order to be illustrated more clearly that technical scheme, below will be to required in embodiment or description of the prior art
The accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only some embodiments of the present invention, right
From the point of view of those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain it according to these accompanying drawings
Its accompanying drawing.
