LED (Light-Emitting Diode) street lamp

Abstract

The invention discloses an LED (Light-Emitting Diode) street lamp, which comprises an LED chip and a heat-conducting substrate, wherein the LED chip is connected with the heat-conducting substrate; the heat-conducting substrate is flaky and is arranged on a heat-conducting pedestal; the heated end of a heat tube is arranged on the heat-conducting pedestal; the cooling end of the heat tube is placed in an air convection cavity; the cooling end of the heat tube is provided with radiating fins which are placed vertically. The LED street lamp disclosed by the invention has the advantages of good heat-dissipating effect, light weight, easiness in installation, prevention of safety accidents, uniform illumination and contribution to improving the adaptability of a driver during driving.

Description

technical field [0001] The invention relates to electronic equipment, in particular to an LED street lamp. Background technique [0002] The heat dissipation performance of the existing LED street lamps is not good, and the street lamps are turned on for a long time to cause aging and light decay, which shortens the service life of the LED street lamps, and the heat dissipation materials of the existing LED street lamps are usually made of copper, which is heavy and has general thermal conductivity. It is beneficial to the installation of street lamps. If it is not installed properly, it will easily hurt pedestrians if it falls. In addition, the existing LED street lamps still have uneven illumination. The area under the LED lamp has strong illumination, but the illumination outside the lamp is very dim, which will cause the driver to be unsuitable when the vehicle is driving, and easily lead to safety accidents. Contents of the invention [0003] The problem to be solved...

Problems solved by technology

[0002] The heat dissipation performance of the existing LED street lamps is not good, and the street lamps are turned on for a long time to cause aging and light decay, which shortens the service life of the LED street lamps, and the heat dissipation materials of the existing LED street lamps are usually made of copper, which is heavy and has general thermal conductivity. Conducive to the installation of street lamps, if the installation is not done properly, it will easily hurt pedestrians

In addition, the existing LED street lamps still have uneven illumination. The area under the LED lamp has strong illumination, but the illumination outside the lamp is very dim, which will cause the driver to be unsuitable when the vehicle is driving, and easily lead to safety accidents.
