In order to overcome the deficiency of existing LED road lamp cooling weak effect, the invention provides a kind of LED streetlamp with favorable radiating effect.
The technical scheme that the present invention solves its technical problem is: a kind of LED street lamp, comprise several LED lamps, and described LED lamp is installed in the heat-dissipating cylinder respectively; Also comprise first heat sink and second heat sink, described first heat sink is positioned at the below of described second heat sink, described heat-dissipating cylinder is installed on the lower surface of described first heat sink, connects by thermal column between described first heat sink and second heat sink; Have the heat loss through convection space between described heat-dissipating cylinder and the heat-dissipating cylinder, described heat-dissipating cylinder, first heat sink, second heat sink and thermal column all are exposed in the air.
Further, described thermal column has several, and the heat loss through convection space is also arranged between the described thermal column.
Further, described heat-dissipating cylinder, first heat sink, second heat sink, thermal column are aluminium matter.
Further, the upper surface of described second heat sink also is provided with and is used for the LED street lamp is installed in installation portion on the light pole.
The present invention also has following additional technical feature: described LED lamp comprises the thimble and the led light source of an end opening, and described led light source is positioned at described thimble and towards the opening of described thimble; Also comprise lens and pressing ring, described pressing ring cowling is located on the openend of described thimble, and the lower end of described lens is buckled on the described led light source, and the upper end of described lens is pushed down by described pressing ring.
Be provided with sealing ring between described pressing ring and the described thimble.
Described sealing ring has downward tube, and described lens insert in the described downward tube, and these lens have bulge loop, and the inwall of described downward tube has scrobicular ring, and the bulge loop of described lens snaps in the described scrobicular ring.
Be connected by attachment screw between described pressing ring and the described thimble.
Beneficial effect of the present invention is: the luminous heat that produces of LED is passed to heat-dissipating cylinder, the heat of heat-dissipating cylinder can be passed to first heat sink again, the heat of first heat sink can be passed to thermal column again, and the heat of thermal column can be passed to second heat sink again.Simultaneously, heat-dissipating cylinder, first heat sink, second heat sink and thermal column all are exposed in the air, and between heat-dissipating cylinder and the heat-dissipating cylinder, have the heat loss through convection space between the thermal column, therefore also can realize heat loss through convection.Therefore, heat dispersion of the present invention is quite good, can prolong the service life of LED street lamp greatly.
