Engineering Ip65 Waterproof Integrated Induction LED Solar Powered Street Light

Solar Street Lights: Sustainable Lighting:

The solar-powered street lighting setup is similar to a small realm of exact cooperation. The fixture acts as the central output part for illumination, and the light-emitting element is responsible for transforming electrical power into light energy—such as fluorescent tubes, sodium lamps, metal halide lamps, and LED light-emitting components. Fluorescent tubes have a light efficiency of more than 80Lm/W and can last up to 8,000-10,000 hours; high-pressure sodium lamps have a light efficiency of about 120Lm/W and a service life of up to 24,000 hours; LED light-emitting components have become the main choice for solar street lamps because of their high brightness, long lifespan, and low power usage. Optical parts control the direction and spread angle of light, mechanical parts guarantee the fixture's steadiness and toughness, and electrical parts work together with the light source for stable running.
The solar module serves as the system's "energy gatherer," made up of solar cells connected in series and parallel, sealed with toughened glass, EVA, and TPT, and framed with an aluminum alloy. Just like a hardworking "small sun," it changes solar radiation into electricity, resists wind and hail, and is simple to set up. The storage battery acts as an "energy storage device," saving electrical energy when there is plenty of light and letting it out when lighting is required, making sure the light source has a constant power supply at night. Functioning as the system's "smart center," the solar regulator provides the best charging current and voltage to the storage battery, stops overcharging and deep discharging, and prolongs the storage battery's service life. Poles work closely with the base: the base holds power cables to support the street lights and keeps the lampposts firmly in place to make the whole system stand upright.
During the day, under the guidance of the smart regulator, solar modules take in solar energy, turn it into electricity, and charge the storage battery pack. At night, the storage battery pack releases electrical energy to power the light source, allowing it to give off light—the whole process is automatic and needs little manual work.
The development of solar street lights has a long history. In 1900, inventor Clarence Kemp got a patent for the design of the first solar street lamp, which started its history. In the 1960s, photovoltaic-powered navigation tools and lighting appeared on streets, and solar lighting was formally established. In 1973, countries around the world actively carried out research on ground-based uses of solar cells, with related projects increasing a lot. In the 1990s, governments all over the world actively promoted clean energy, leading to a fast increase in the use of solar street lights in civilian, commercial, and industrial fields. Today, with the progress of LED and new battery technologies, solar street lights are popular in street lighting systems because of their high energy efficiency, long service life, and low maintenance requirements. By 2022, their market size had reached $4.56 billion, and the Asia-Pacific region had become the largest market.
Solar street lights can be divided in many ways. According to the energy source, they directly use solar energy—a clean energy; according to the power supply way, they are self-contained and don't rely on the traditional power grid; according to the application, they are widely used in street lighting, park decoration, industrial building, military places, airports, parking lots, and other situations; according to the lamp head design, there are many different shapes.
Their advantages are obvious. In terms of environmental protection and energy saving, they use solar power to achieve zero carbon emissions, don't need to consume fossil fuels, reduce the release of pollutants, and effectively reduce the power grid load—especially suitable for remote areas or regions with insufficient grid coverage. Installation and maintenance costs are low: independent photovoltaic panel power supply means no need for wiring, which greatly reduces construction difficulty and expenses. LED light sources have a long lifespan of 5,000-100,000 hours, while photovoltaic panels and battery packs have a design life of 5-8 years and need little maintenance. They are highly flexible and adaptable, can work off-grid, and are suitable for mountainous areas, islands, temporary road construction lighting, and other scenarios. They also have intelligent control functions such as light sensing and time control, which can automatically adjust brightness to fit different environments. In terms of policy and economy, many countries provide subsidies for renewable energy projects. Long-term operating costs are lower than those of traditional street lights, so they are very economical.
