How to extend the service life of solar street lamp?

<p>With the continuous advancement of the national construction process, <a href="https://www.srssolargroup.com/solar-street-light" target="_blank">solar street lamp</a>&nbsp;are gradually applied in many industries, and the market competition is increasingly fierce. The widespread use of solar streetlights is a good thing, but all sorts of problems arise soon after they are installed.</p><p><br></p><p>Ways to extend the service life of solar street lamp</p><p><br></p><p>1. Choose high-quality solar panels</p><p><br></p><p>The main function of solar panels is to collect light sources and convert light energy into electricity. At present, the quality of solar panels on the market is uneven, and some black-hearted manufacturers use to reduce costs, invalid pieces or even with paper fraud. When solar panel of choose and buy, must not because the price is low and be deceived by such product, must choose the product that quality has assurance.</p><p><br></p><p>2. Solar street lamp poles</p><p><br></p><p>A good <a href="https://www.srssolargroup.com/solar-street-light" rel="noopener noreferrer" target="_blank"><strong>solar street lamp</strong></a> relies on it for most of its support. The service life of the lamppost depends entirely on what kind of galvanizing is used. Good lamppost USES hot dip galvanization, the lamppost life that produces so can be as long as 20 years above, use cold galvanization lamppost however, in outdoor use 1-2 months can appear rust spot, time grew can exist certain safety hidden trouble.</p><p><br></p><p>3. Solar LED lights</p><p><br></p><p>The quality of LED lights has a direct impact on the use effect. When choosing suitable solar lamps, in addition to considering the energy saving and environmental protection characteristics of the products, the stability and economy of the products should be considered. Want to raise lamps and lanterns service life to be about to choose quality to depend on firmly, thick lamps and lanterns, additional lamp bead also is crucial, cannot coddle cheap to use patch, the life of the solar energy street lamp of words with bad heat is met greatly discount.</p><p><br></p><p>4. The battery</p><p><br></p><p>Battery is strong backing, solar street lamp&nbsp;battery because the volume is larger, generally adopt the way of ground for installation, can not only anti-theft function, and can provide a relatively constant temperature of the environment for the battery, the battery solar street lamp&nbsp;type is more, the current use of lead-acid maintenance-free batteries, ordinary lead-acid battery, gel battery and alkaline nickel cadmium battery.</p><p><br></p><p>5. The controller</p><p><br></p><p>Solar street light controller is a solar lighting system in the central nervous system, responsible for coordinating the solar panels, lithium batteries, load of work, is in the solar street lighting system for key components, the controller has the function of preventing overcharge discharge, waterproof, steady voltage, current prompted the solar lighting system efficient and safe operation.</p><p><br></p><p>The components of a solar street lamp</p><p><br></p><p>The controller is intelligent controlled by microcomputer. The photovoltaic controller has the functions of overcharge and overdischarge, output short-circuit protection, light control and time control. It has passed the index test of the industrial product quality supervision and inspection center of the ministry of information industry. With constant current, soft start, half power, reverse connection, lightning protection, temperature compensation and other protection functions. Charge, overdischarge, load, display indicator light are marked. The cable adopts national standard 4.0mm2 conductor as the core wire</p><p><br></p><p>The underground storage box of the battery is a special underground storage box for solar street lamp, with waterproof and cold protection measures, can effectively resist rain and low temperature damage to the battery, is the battery in the normal range of operation.</p><p><br></p><p>The battery USES a sealed maintenance-free lead-acid battery of 120AH, which is installed underground. Cycle durability, long life, quality assurance period of 3 years, the actual life of more than 8 years. Small self-discharge, high charging efficiency. Small internal resistance and self - discharge, good current discharge characteristics. The operating temperature ranges from -30 to 45 degrees. Environmental protection, safe and reliable sealing technology.</p><p><br></p><p>The solar lamp pole technology requires the tapered pole to be 6 meters high, the lamp arm to be 1.3 -- 1.35 meters long, and the lamp holder to be 6 meters above the ground. The main pole adopts high quality steel tube, the lamp pole weld line is smooth, neat does not have burr, the hot dip galvanization anticorrosion treatment, the surface spray is plastic. Lamp post service life 20-25 years.</p><p><br></p><p>The shell adopts heat dissipation integrated casting aluminum lamp shell, which has strong heat dissipation function and low heat loss and light loss: adopt aluminum based PCB board welding technology, the light loss within one year should not be more than 10%, and the small particles of 5 mm do not need to be equipped with heat sink), working at room temperature for 10 hours, and the temperature rise on the surface and interface of heat sink ≤15℃. Led light source working voltage range dc11v-14v can be used normally, in the range of -25℃ -50 ℃ can be used normally.</p><p><br></p><p>LED light source with three generations of LED cold light source, efficiency compared with incandescent lamp, energy saving efficiency can reach more than 90%. At the same brightness, power consumption is only 1/10 of that of a regular incandescent lamp, 1/3 of that of a fluorescent lamp, and 1/2 of that of a low-voltage energy-saving lamp. Effective service life 5500 hours. Easy to install, can carry out any power combination. Current limiting protection: the use of IC multi-stage current limiting protection, high reliability.</p><p><br></p><p>The transparent cover is made of anti-aging EVA resin, TDT composite film lamination with excellent weather resistance, anode lead oxide frame, high mechanical strength, wind resistance, hail resistance, corrosion resistance and other properties. For all kinds of complex bad weather can be used, the output terminal USES sealed waterproof, high reliability, multi-functional junction box. Install bypass diode, effectively prevent hot spot effect and line protection, wiring convenience.</p><p><br></p><p>Solar panel power generation efficiency of 15.5%, stable performance, service life of up to 30 years of monocrystalline silicon solar panels, in line with international standards. Using imported high-efficiency solar cells, using high strength, high and low iron ultra-white toughened glass, reduce the reflection of sunlight.</p>
