Solar street lights should not only illuminate rural roads in mountainous areas, but also a new generation of solar street lights are entering urban traffic arteries, partially replacing city street lights. This is a development trend, and this trend is becoming more and more obvious. Members of the New Energy Lighting Committee, enterprises should be fully prepared, carry out strategic planning, complete the reserve of system technology, improve manufacturing capabilities, improve the supply chain and industrial chain, prepare for a rainy day, and welcome the burst of incremental markets.
Since 2015, when LED light source street lights were relatively mature and applied to road lighting on a large scale, my country's road lighting has entered a new stage. However, from the perspective of street light application across the country, the penetration rate of LED street lights is less than 1/3, and many first-tier and second-tier cities are still mainly based on high-pressure sodium lamps and quartz metal halide lamps. With the acceleration of carbon emission reduction, it is an inevitable trend for LED street lights to replace high-pressure sodium lamps. This replacement will have two situations: one is that LED light source street lights replace some high-pressure sodium lamps; the other is that solar LED street lights replace some high-pressure sodium lamp street lights.
It was also in 2015 that lithium batteries began to be used on a large scale for photovoltaic street light energy storage, which improved the energy storage quality, and the application of supercapacitors was earlier. The progress of energy storage technology has given birth to combined high-power photovoltaic street lights. In December 2017, Changsha Dongzhu Expressway, 12.3 kilometers long, with 6-8 lanes in both directions, was the first to adopt the 240-watt combined high-power photovoltaic street lights developed by "Hunan Naipun Company", which was the first solar street light project that used supercapacitor energy storage; in 2016, Anhui Langyue Company won the bid for G104, with eight lanes in both directions, and installed 180-watt high-power photovoltaic street lights; in August 2020, Shandong Zhiao successfully developed copper indium gallium selenide soft film components and lamp poles, single-system high-power, 150 solar street lights, which were first applied in the Zibo West 5th Road Interchange, opening a new stage of single-system high-power photovoltaic street light application-the main road lighting stage, which is remarkable. Its biggest feature is that it has achieved single-system high power. After the soft film, there appeared high-power photovoltaic street lights that integrated monocrystalline silicon and lamps, monocrystalline silicon, shingled components and lamp poles. In order to replace some qualified 12-meter-high street lights of the city power, the technical reserve has been completed.
Compared with the mains street lamp, this 12-meter-high solar street lamp has many advantages. It can completely replace the mains street lamp in places with suitable lighting conditions. The maximum power of a single system can reach 200 to 220 watts. If a 160 to 200-lumen LED light source is used, it can be fully applied to the lighting of two-way six-lane roads such as ring roads and expressways. There is no need to apply for mains quota, lay cables, or transformers, and no earthwork or backfilling is required. If designed according to the standard, it can fully meet the energy storage needs of seven rainy, foggy and snowy days, and the life span is up to three, five, and eight years; the energy storage of solar street lamps for 3-5 years is recommended to use lithium batteries, and supercapacitors can be used for 5-8 years. The current controller technology can not only monitor and feedback whether the working status is on, but also access professional management platforms to provide big data on power generation and energy storage status for carbon emission reduction and carbon trading.
The fact that solar street lamps can replace mains street lamps is a major new energy lighting technology advancement, which is gratifying. This is not only the need for social development, environmental protection, energy conservation and emission reduction, but also the rigid demand of the street lamp market, and it is also an opportunity provided by history. Not only the domestic market is facing a large number of substitutions, but the international market is even more so. In the context of global energy shortages, energy structure adjustment and carbon emission reduction, solar lighting products are more popular than ever before. At the same time, a large number of garden lights and landscape lights are also in urgent need of upgrading.
It is recommended that companies should prepare the design, manufacturing and system technology of high-power street lights that integrate components and lamp poles, components and lamps as soon as possible to welcome the arrival of the major replacement stage of street lights.
In the process of promoting this technology reserve, Luxsky-light recommends giving priority to solutions with higher intelligence and convenience. Our latest high-power solar street lights with dual modes of light control and timing and detachable integrated driver are the perfect tool for upgrading urban main road lighting. Its intelligent control strategy optimizes energy utilization, and the detachable drive design greatly simplifies later maintenance, significantly reduces the cost of the entire life cycle, and makes efficient and reliable urban solar lighting within reach.Click the link to view detailed parameters.
