Durable LED street lamp

Abstract

The invention discloses a durable LED street lamp. The durable LED street lamp comprises an upper shell and a lower shell. A cooling plate is arranged in the upper shell, and cooling fins are distributed at the upper end of the cooling plate; an aluminum substrate is arranged at the lower end of the cooling plate, and an LED light-emitting component is arranged on the lower surface of the aluminum substrate; a lampshade located in front of the LED light-emitting component covers the lower shell; and the upper end of the upper shell is fixedly mounted at the outer ends of the cooling fins from outside to inside, and a streamline protection cover covering the cooling fins is arranged at the top end of the upper shell. A plurality of concave edges are arranged on the protection cover at intervals in the length direction, and a plurality of ventilation holes are distributed in the bottom of each concave edge. The design that the streamline protection cover is arranged on the upper shell is adopted, and on the premise that the cooling performance of the cooler is not affected, the influence that acid rain and corrosive substances remain in gaps and grooves of a radiator, and the radiator is corroded is effectively prevented. The cooling effect of the LED street lamp is ensured, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to a durable LED street lamp. Background technique [0002] LED lighting products are gradually replacing traditional lighting fixtures as mainstream lighting products, not only have the characteristics of good chromaticity, easy maintenance, long life, but also more energy-saving than traditional street lamps. LED street lights will generate a lot of heat during use, and good heat dissipation performance is an important guarantee for the normal operation and service life of LED street lights. However, the existing LED street light radiator structure is not reasonable enough, and the gaps and grooves on the radiator structure are not enough. Acid rain and corrosive substances are easy to remain inside, and it is easy to be corroded when exposed to the air for a long time, which not only affects the appearance and heat dissipation performance of the product, but also affects the mec...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a durable LED street lamp to solve the unreasonable structure of the radiator of the traditional LED street lamp in the prior art. Acid rain and corrosive substances are easy to remain in the gaps and grooves on the radiator structure. It is easily corroded in the air, which not only affects the appearance and heat dissipation performance of the product, but also affects the mechanical strength and service life of LED street lights.
