An intelligent led street lamp with strong illumination brightness suitable for wet weather

Abstract

The invention relates to an intelligent LED street lamp with high radiation brightness for humid weather. The intelligent LED street lamp comprises a lighting mechanism, and the lighting mechanism comprises a lamp housing, a lamp tube, an air intake mechanism, an air guide mechanism and a defogging mechanism; the defogging mechanism comprises a translational component, a connecting block, a nozzleand a hot air pipe; the translational component comprises a first motor, a damping block, a first driving shaft and a sliding block; and the air intake mechanism comprises an air inlet pipe, a connecting pipe and a dehumidification component arranged in the air inlet pipe, and the dehumidification component comprises a dehumidification unit, a first screen plate, a drying layer, a second screen plate and a valve. According to the intelligent LED street lamp with high radiation brightness for humid weather, hot air in the lamp housing is led out through the defogging mechanism for heating thesurface of the lamp housing, and moisture on the surface of the lamp housing is removed; the radiation brightness of equipment is recovered, and the driving safety at night is ensured; in addition, introduced external air is dried through the air intake mechanism, and damp air is prevented from entering the lamp housing, resulting in damage to the equipment, so that the safety and reliability of the equipment are improved.

Description

technical field [0001] The invention relates to the field of outdoor lighting equipment, in particular to an intelligent LED street lamp with strong irradiation brightness suitable for wet weather. Background technique [0002] Road lighting is an important part of urban lighting. Traditional street lights often use high-pressure sodium lamps to emit light at 360°. The disadvantage of large light loss has caused a huge waste of energy. The difference between LED street lamps and conventional street lamps is that the LED light source adopts low-voltage DC power supply, high-efficiency white light synthesized by GaN-based power blue LED and yellow, which has high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index. Unique advantages, widely used in road lighting at night. [0003] However, when the existing LED street lamps are in humid weather such as rainy or heavy fog, due to the increase of humidity i...

Problems solved by technology

[0003] However, when the existing LED street lamps are in humid weather such as rainy or heavy fog, due to the increase of humidity in the air, the water vapor in the air is easy to cover the surface of the lamp housing, which will also cause many water droplets to appear under the lamp housing. It not only changes the propagation direction of light, but also reduces the brightness of light irradiation, resulting in low brightness of LED street lights in wet weather, which is easy to cause some traffic accidents, thereby reducing the practicability of existing LED street lights
