Abstract

The invention relates to an LED street lamp, which comprises a lamp shell, a heat radiator arranged on one end face of the lamp shell, a lampshade arranged on the other end face of the lamp shell, and a driver arranged in the lamp shell, wherein heat transfer devices are arranged in lamp shell cavities which are positioned on the heat radiator and are coaxial with the lampshade respectively, the bottom of the heat transfer device is connected with a high-brightness light source, and a reflecting shade of which the covering surface corresponds to a transparent surface of the lampshade is clamped between the bottom of the heat transfer device and the high-brightness light source. The heat transfer device consists of a sealed cavity formed by a conical shell and the heat radiator, and a heatconducting fusing agent filled in the sealed cavity. The LED street lamp uses vaporization heat transfer and liquefaction heat exchange to heat the heat transfer liquid by the heat generated in the working process of an LED module through the heat transfer shell, and when the temperature reaches the boiling point of the heat transfer liquid, the liquid is boiled and vaporized, the gas can quicklytransfer the heat to the heat radiator, and the heat radiator liquefies the gas into liquid which falls back to the heat transfer shell for transferring heat continuously after the heat exchange between the heat radiator and the heat transfer gas.

Description

technical field [0001] The invention relates to an LED street lamp. Background technique [0002] CN200810022209.2 discloses a "multi-light source LED street lamp". Its purpose is to provide a multi-light source LED street lamp, which can effectively reduce the installation quantity and cost of street lamps, improve the luminous efficiency of LED street lamps and solve the heat dissipation problem of high-power LED street lamps, and extend the length of LED street lamps. service life. Its technical composition: the multi-light source LED street lamp, the middle part of the upper lamp housing is a heat transfer substrate, the outer surface of the heat transfer substrate is provided with a number of heat sinks, the boss is fixed under the heat transfer substrate inside the upper lamp housing, and the boss The upper interval is provided with a plurality of annular grooves for sealing rings. The heat-conducting substrate of the LED light source module is fixed on the boss in t...
