Wind power combined water-refrigeration LED road lamp

Abstract

The invention discloses a hydrocooling LED street lamp integrated with wind-force. The lamp comprises a high power LED diode, a substrate, a heat sink, a water self-circulation device and one or more than one wind-force stirrer devices, wherein the diode is fixed on the substrate which possesses a favorable heat-conducting property; the substrate is connected with the heat sink tightly; the heat sink and the water self-circulation device form a favorable heat-conduction connection; the water self-circulation device is equipped with one or more wind-force stirrer devices. The beneficial effectof the invention is that the water circulation is accelerated by employing the wind-force stirrer device in order to cool the hear sink of the LED street lamp head. This invention possesses simple structure, low cost, favorable heat-radiation effects and employs wind-force to accelerate the circulation of the water without extra power; the LED can work at a lower temperature by such mean, and keeps a high luminous efficiency; thus the high power LED can radiate heat in time and the service life of the LED is prolonged, and finally the service life of the whole lamp is prolonged as well.

Description

A water-cooled LED street lamp combined with wind power technical field The invention relates to the cooling of an electric heating body, in particular to a water-cooled LED street lamp combined with wind force that can quickly dissipate heat from a high-power LED lamp cap. Background technique In recent years, with the continuous development of LED material epitaxy and chip technology, LED luminous efficiency has been continuously improved, and its application fields have gradually expanded. Experts also predict that LED will replace incandescent and fluorescent lamps as a new generation of lighting sources. Compared with traditional incandescent lamps and fluorescent lamps, LED lighting sources have great advantages: ① LEDs are small in size, long in life, and compact in structure to achieve large-area arrays. Moreover, LEDs do not contain lead and mercury that are harmful to the human body, and at the same time avoid ② LED is driven by low-voltage DC power supply, so t...
