Problems solved by technology

Although this street lamp can play a certain role in purifying the air and removing dust, its purification efficiency is relatively poor. In particular, although the spraying of the liquid medicine has the effect of sterilization and disinfection, the sprayed liquid medicine is dispersed in the air, which will cause damage to the environment. Hazards to the human respiratory system
In addition, the nozzle and the water delivery pipeline of the high-pressure water spray street lamp are easily frozen in cold weather, causing the pipeline to rupture, which will cause the water spray system to not work normally and have a short service life. The space is small, making maintenance or replacement extremely inconvenient, and poor promotion and application

Abstract

The invention discloses an LED streetlamp for an urban viaduct. The LED streetlamp comprises a hollow lamp post and an LED streetlamp body and further comprises a water delivery pipe, a water tank, a water pumping pipe, a water pump and a control box. The lower end of the water pumping pipe is connected with the water pump, the upper end of the water pumping pipe is connected with an atomization nozzle, and the atomization nozzle is arranged on the top of the lamp post. A single-chip microcomputer and an anion generator are arranged in the control box. The water delivery pipe and the water pumping pipe are respectively sleeved with a heat preserving pipe made of foamed plastic, and each heat preserving pipe comprises, by weight, 100 parts of polyvinyl chloride, 12-16 parts of azodicarbonamide, 1.2-1.5 parts of sodium bicarbonate, 10-20 parts of urea formaldehyde, 0.5-0.8 part of dicumyl peroxide, 5-10 parts of ethylene-vinyl acetate copolymer and 0.6-0.8 part of silicon dioxide. The LED streetlamp for the urban viaduct can purify air and is good in dustproof effect and long in service life.

Description

technical field [0001] The invention relates to the technical field of urban lighting, in particular to an LED street lamp for urban viaducts. Background technique [0002] Street lamps are mainly used for urban road lighting, providing convenience for people to travel at night, and are an essential infrastructure for urban road construction. At present, there are many vehicles on urban roads, and the exhaust gas and dust emitted by factories lead to environmental pollution, turbid air, smog, which seriously affect people's health; and the urban viaduct is the most serious air pollution hazard in the city, because its height from the ground is relatively high. It is high, and there are no trees on the viaduct to block it. The exhaust gas emitted by cars can easily spread with the air flow. [0003] In order to improve the air quality in the city, people think of using the light pole of the street lamp as a support, setting a high-pressure water nozzle on the top of the ligh...
