A led street light with automatic heat dissipation

Abstract

The invention relates to a solar street lamp, in particular to an automatic heat dissipation LED street lamp, comprising a lamp post, a lampshade, a solar battery panel, a rotating water supply device, a water storage tank and a heat dissipation pipe. The rotating water supply device is located above the light pole and includes a support rod, a rotating shaft, a water storage plate and a water supply plate. The invention utilizes the gravity of rainwater to drive the rotating device and utilizes rainwater as a heat dissipation medium to complete the automatic heat dissipation of LED lamps, which saves energy resources and does not require manpower manipulation. The lowest point of the radiating pipe located outside the lampshade communicates with the water storage tank, so that the heat in the lampshade can fully exchange heat with the air, so that the water in the radiating pipe can be reduced as much as possible before exchanging heat with water, ensuring good and Reliable cooling effect. In the case of non-rainy days, the water supply plate is in a vertically downward state, effectively avoiding the accumulation of dust.

Description

technical field [0001] The invention relates to a solar street lamp, in particular to an automatic heat dissipation LED street lamp. Background technique [0002] Street lamps are the most common equipment for urban road lighting, and with the advancement of technology, solar powered circuit lamps and street lamps using LED light sources are increasingly used. For the protection of LED lamps, in order to prevent them from being damaged due to dust and water, LED lamps are often placed inside the lampshade, which leads to the lamps being in a relatively closed cavity, causing problems such as difficulty in heat dissipation, which seriously It affects the normal luminescence of the lamp and shortens the service life of the lamp. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides an automatic heat dissipation LED street lamp, which uses flowing water as a heat dissipation medium, so that the LED light can obtain a good ...
