Further, described fin (11) forms multiple concaveconvex structure in the vertical direction to increase heat exchange area.
Further, sidewall fan and bottom fan realize being used alternatingly at both ends of power by lines in parallel.
This LED street lamp has following beneficial effect:
(1) the utility model luminescence unit by being respectively equipped with LED chip and reflectance coating on V-type mounting groove two hypotenuses, the light that LED chip is launched just starts to carry out first reflection and even light in lampshade, and make the final light penetrated from lampshade more all even bright, and more meet human eye vision requirement.
(2) the utility model arranges vertical ventilation passage and horizontal ventilation passage in radiator, the heat conduction that LED chip is easily distributed by vertical ventilation passage is on fin, but because having a narrow range of temperature in vertical ventilation passage between hot-air and fin causes the heat exchange efficiency of fin and hot-air low, so by arranging horizontal ventilation passage, the cold air of outdoor relative low temperature is imported, and the hot-air after heat exchange is derived fast, thus substantially increase the heat exchange efficiency of fin, also improve the radiating efficiency of LED lamp.
(3) the utility model vertical ventilation passage and the alternation of horizontal ventilation passage, avoid two air channels mutually to disturb, cooperatively interact both guaranteeing cooperation simultaneously, vertical ventilation passage is by heat from LED chip heat exchange to fin place, and heat imports in the environment of relative low temperature from fin by horizontal ventilation passage.
