Something important about the dustproof and windproof design of LED street lights

Spring is the season with the most windy weather. Every year, there are accidents of light poles being blown down by strong winds. LED street lamp lamps and lanterns are often damaged due to high winds, and the phenomenon of wind dust is also important for shortening the life of the lamps and reducing their brightness. the reason. Therefore, when we choose LED street lights, we must not only consider its aesthetics and practical functions, but also pay attention to the windproof and dustproof functions of the lamps and poles. Only in this way can we ensure the safety of LED street lights in urban infrastructure. Use, bring convenience to people's travel and life production.

1. The dustproof of LED street lamp can be reasonably selected according to the air pollution migration degree, dust content, investment cost and maintenance conditions of the illuminated place. Another simple and feasible dustproof design for lamps is to install a waterproof and breathable rubber strip on the contact part between the lampshade and the lamp holder. The waterproof and breathable rubber strip is a material that is breathable but impermeable, and natural rubber is used. Or recycled rubber to guarantee the service life. In addition, the LED drivers, LED chips and other components used in the lamps will generate a lot of heat. Therefore, the glass material should be given priority in the selection of the lamp lens. In the past, most lampshades made of acrylic or synthetic plastic were used, which will appear after a few years of use. The aging phenomenon of the lampshade causes poor light transmittance of the lamp, which affects the brightness of the LED street lamp. In addition to the dust inside, it cannot be cleaned after high temperature. The lampshade or the entire lamp needs to be replaced to meet the requirements of use, which undoubtedly increases the maintenance cost. Adding a sealing rubber ring to the joint of the lamp components to prevent dust from entering the lamp shade from the lamp cap is also an aspect of the lamp dust.

2. Windproof of LED street lights

(1) Lamps are an important part of LED street lamps. The quality and opening method of lamps are very important. The material must be aluminum casting alloy, and the thickness must meet the requirements. No cracks or holes in the lamp body are allowed, and the joints of various components must be good The contact point and the buckle part are the top priority. The unreasonable buckle design of the previous lamps caused a large number of lamps to be damaged after the strong wind. Therefore, it is necessary to use spring buckles on the lamps and it is best to install two First, the upper part of the lamp is opened directly, and important parts such as the LED driver are fixed on the lamp body to prevent the parts from falling off after the lampshade is damaged and causing a safety accident.

(2) Light pole The height of the light pole must be selected according to the road width and usage conditions, the wall thickness must be above 3.5mm, the inside and outside hot-dip galvanized, the thickness of the galvanized layer is above 35μm, the thickness of the flange is above 18mm, and the flange and the lamp Reinforcing ribs should be welded between the poles to ensure the strength of the bottom of the pole. In the past, because the lamp poles were unqualified in galvanization and there was no welding reinforcement, the bottom of the lamp pole was seriously corroded, and the phenomenon of the lamp pole being blown off by the wind occurred from time to time. Therefore, the wall thickness of the pole, the thickness of galvanizing and whether to add welded reinforcement are important signs of whether the pole is qualified or not, otherwise it cannot be used.

(3) Basic street lamp foundation as a concealed project of LED street lamp project, it is also very important for the overall windproof and safe use of street lamp. First, choose C20 concrete for pouring. The choice of anchor bolts depends on the height of the light pole.

For 8m light poles, choose Φ20 bolts, with a length of 1100mm and a base depth of 1200mm;

For 10m light poles, choose Φ22 bolts with a length of 1200mm and a base depth of 1300mm;

For 12m light poles, choose Φ22 bolts with a length of 1300mm and a base depth of 1400mm;

The lower part of the foundation is larger than the upper part, which is conducive to the stability of the foundation and enhances the wind resistance.

In short, as the role of LED street lights in urban roads is gradually improving, road lighting must not only meet the requirements of use and enhance the taste of the city, but also be safe, reliable, durable, provide people with a good travel and living environment, and create social benefits. Save maintenance costs.
