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.
Further, described substrate has the groove being fixed with the raised line on described radiator.
Specifically, 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:
(1) LED street lamp of the present invention have that compact conformation, production cost be low, dust and moisture, good heat dissipation effect, illumination steady
Fixed, the advantage of length in service life.
(2) 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.
(3) 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.
(4) mounting seat of radiator is set to grid-like, the flowing of shell inner cavity air can be beneficial to, be beneficial to heat radiation.In addition
The lateral surface of arc-shaped cover arranges radiating fin, can further improve radiating efficiency.
(5) in the present invention, casing of street lamp has arc-shaped cover, and arc-shaped cover will not produce hydrops.
