Explore the practicality of solar street lights

Practical solar lighting products are referred to as practical solar street lights. They have obvious energy-saving effects, easy installation and safe use. Various optical indicators can reach or be close to ordinary power lamps, which can meet the lighting requirements of users and meet relevant industry standards. Practical solar lamps focus on the word practical, which not only conforms to China's national conditions of consumption, but also conforms to China's current energy-saving policies and environmental protection policies. It has a very broad prospect and can produce various social and economic benefits, mainly including: 1. Comprehensive social benefits— - Energy saving: my country is a big energy-consuming country, and its oil consumption ranks second in the world after the United States, but it is also a weak country in energy reserves and production. The proven oil reserves per capita in my country only account for the world's 7.7% of the per capita recoverable reserves. For more than 20 years, my country's oil and natural gas imports have increased sharply year by year. In 2004, the imported oil exceeded the 100 million tons mark, and in 2005, it reached 136 million tons, equivalent to one year for every Chinese. To import 100 kilograms of oil, is my country's largest import of commodities. China will continue to develop rapidly, which means that it will consume more energy in the future. Weak energy reserves make my country's energy situation even more severe. Since 2003, every summer in my country, there has been a nationwide shortage of power supply. In 2004, 19 large and medium-sized cities across the country were forced to cut off electricity during peak hours of electricity consumption. nervous. The shortage of energy has seriously affected the production and people's life in the whole country, and the search for alternative energy has become an urgent matter. Among various recyclable energy sources, solar energy ranks among the forefront of alternative energy sources due to its non-polluting, renewable, safe, reliable and local collection characteristics. If the application of solar photovoltaic power generation can be promoted nationwide, the national power shortage may be alleviated or avoided. 2. Environmental protection: Solar photovoltaic power generation is a kind of static power generation, it does not need oil, coal, no running parts, no three waste emissions, no noise pollution, and it provides a kind of clean energy. Photovoltaic power generation uses sunlight, which can block part of the summer sun rays and reduce the summer temperature, which is a good thing that kills three birds with one stone. 3. Safety: There are no safety hazards for solar lamps. Solar lamps are low-voltage products, the working voltage is generally 12~24V DC voltage, the operation is safe and reliable, and there is no danger of electric shock to people. The mains lighting fixtures use 220V AC voltage, which may bring many safety hazards due to the influence of construction quality, material aging, power supply voltage, cross-conflict of water and electricity pipelines, etc. With the increasing shortage of disposable energy and the enhancement of national awareness of environmental protection, practical solar lamps will surely be popularized and applied in a large area. For example, when Beijing bid to host the 2008 Olympic Games, one of the slogans put forward by the bid committee was: Green Olympics, Green Olympics. Beijing is going to build an Olympic Village that mainly relies on solar power for heating, and all the competition venues will use a lot of solar energy facilities, of which large solar lamps will play the leading role in the outdoor lighting of the Olympic Village. bus street sign kiosk. These all paved the way for practical solar lamps to enter the national market. It can be predicted that solar lamps will make a big difference in China in the 21st century.
