Cooling and dust removal LED street lamp based on Bernoulli principle

Abstract

The invention belongs to the field of LED street lamps and particularly relates to a cooling and dust removal LED street lamp based on a Bernoulli principle, and the street lamp comprises a lamp body;and the lamp body comprises a lamp holder and a lamp cover, an LED lamp tube is fixedly connected to the interior of the lamp holder, the middle of the bottom surface of the lamp holder is arranged in an upward hunch-up mode, a plurality of radiating holes are formed in the peripheral side wall of the lamp cover, a horizontally arranged cooling fan is arranged at the upper end of the LED lamp tube, the cooling fan is rotationally connected with the inner side wall of the lamp holder through a fixing ring, a rotating shaft of the cooling fan is movably connected with a threaded rod through a one-way bearing, the upper end of the threaded rod is rotationally connected with the center of the inner bottom surface of the lamp holder, a driving plate is arranged on the threaded rod in a sleeving mode, and a through hole matched with the threaded rod is formed in the driving plate. Wing plates are arranged, and the lower edges of the wing plates are arc-shaped lines arching downwards; when awind blows towards the wing plates, not only dust removal scraping plates are driven to slide and remove dust, but also the driving plate can be driven to move to enable the cooling fan to rotate forcooling, energy input is avoided, environmental protection and energy conservation are achieved, and the service life of the LED street lamp is further prolonged.

Description

technical field [0001] The invention belongs to the field of LED street lamps, in particular to a temperature-cooling and dust-removing LED street lamp based on Bernoulli's principle. Background technique [0002] Road lighting is an important part of urban lighting. Traditional street lights are often used. High-pressure sodium lamps emit 360 degrees of light. The disadvantage of large light loss has caused a huge waste of energy. At present, the global environment is deteriorating day by day, and countries are developing clean energy. With the rapid growth of the national economy, energy saving is an urgent problem to be solved. Therefore, the development of new high-efficiency, energy-saving, long-life, high color rendering index, and environmentally friendly LED street lights is of great significance to urban lighting energy saving.

[0002] Road lighting is an important part of urban lighting. Traditional street lamps are often used. High-pressure sodium lamps emit light at 360 degrees. The disadvantage of large light loss has caused a huge waste of energy. At present, the global environment is deteriorating day by day, and countries are developing clean energy. With the rapid growth of the national economy, energy saving is an urgent problem to be solved. Therefore, the development of new high-efficiency, energy-saving, long-life, high color rendering index, and environmentally friendly LED street lights is of great significance to urban lighting energy saving.

[0003] Most of the traditional LED street lamps are simply spliced ​​by the lamp shell and the LED lamp tube. When the LED lamp tube is lit and continues to heat up, the temperature inside the lamp body will gradually increase, because the street lamp usually lasts for dozens of hours. Hours, so the internal components of the lamp body will be at a relatively high temperature for a long time. Over time, it will cause damage to the circuit in the lamp body and reduce the service life of the LED street lamp. Moreover, for some lamp bodies, there are As far as street lights with solar panels are concerned, dust is easy to fall on the solar panel, and the dust is easy to cause the solar panel to have a spot effect, which affects the use effect of the solar panel
