Abstract
The invention discloses a high-power LED street lamp which comprises a lamp pole, a lamp holder, an LED lamp, a lamp cover, an LED substrate and a power supply. The high-power LED street lamp is characterized in that a radiating liquid tank is arranged close to the LED substrate, and radiating liquid is filled in the radiating liquid tank and forms circulation outside the radiating liquid box through a circulating liquid pipe. The radiating liquid circularly flows in the radiating liquid tank and the circulating liquid pipe and quickly transfers heat generated by high-power LED during working. The high-power LED street lamp effectively solves the technical problem of radiation of high-power LED lamps and guarantees the service life of the high-power LED street lamp. The lamp cap, the lamp holder and the lamp pole of the LED street lamp form an integrated radiating device, and the weight of the lamp cap is reduced. Because the weight of the lamp cap is light and the size is small, the weight of the lamp holder and the lamp pole is correspondingly lightened, thus the cost is reduced. The lamp pole is of a separable type and is easy to manufacture and convenient to mount.
