The development prospects and application status of Solar LED lighting

Concerns about security of energy supply and climate change with the development of human society, has gradually been increasing emphasis on the world, and each began to use various means to sustainable energy development. Indirectly promote the rapid development of renewable energy technologies and worldwide industry, such as the annual growth rate of photovoltaic power, wind power, etc. in more than 20%. Although renewable led high bay light for sale has now realized diversification of energy sources, but coal and crude oil is still hot international energy sector.

As of the first half of 2014, China's hydropower installed capacity reached 290 million kilowatts, wind power capacity has reached 83 million kilowatts, solar power installed capacity reached 22 million kilowatts. Among them, the renewable energy power generation capacity of more than 30% of total power generation capacity of renewable energy generating capacity of more than 20% of total electricity generation of electricity. Can be used as the main energy renewable energy development has become a hot international energy sector, has been widespread concern in many countries of the world.

Green has taken a big step

With the increasingly scarce resources of the earth, the investment cost basis of energy rising, safety and pollution risks are everywhere, solar energy as an "inexhaustible" security, environmental protection and new energy increasingly the more attention. At the same time, but also with the development of solar photovoltaic technology and progress, solar lighting products in the dual advantages of green energy, solar lights, garden lights, lawn and other applications has gradually scale solar power development in the field has increasingly improved street lighting .

As a green LED light source, high luminous efficiency, low power consumption, long life, high security and reliability features. LED single tube power from 0.03 to 0.06 watts, DC-driven, single-tube drive voltage of 1.5 to 3.5 volts, the current 15 to 18 mA, reaction speed, can operate at high frequencies. The same lighting effects, the power consumption is one millionth of incandescent bulbs, fluorescent tubes half, Japan is estimated as the use of fluorescent light efficiency is even higher than twice the LED replacement of incandescent and half in Japan fluorescent lamps. Annual savings equivalent to 6 billion liters of crude oil. Lights on the bridge parapet cases, the same effect a fluorescent lamp more than 40 watts, while the use of LED only 8 watts of power each, and can be color changes. With economic development, China's lighting electricity will greatly increase the research application of green energy-efficient lighting, will more and more attention. On this basis, it was the beginning of the LED light source associated with solar energy, hoping to allow night lighting with solar energy during the day and reserve seamlessly connected. This will be a big step in the green.

Currently, led street light with solar panel consumes about 20% of the overall electricity consumption, electricity consumption is an important way to reduce lighting energy savings. To achieve this goal, the industry has developed a variety of energy-efficient lighting fixtures, and have achieved some results. However, from the "green light" requirement is also far, the development and application of more efficient, reliable, safe, durable, new light is imperative.

Solar LED lighting as a cold light source products with higher cost, green, safe, reliable, stable quality, long life, easy installation and maintenance, etc., can be widely used in green lighting, road lighting, advertising light box lighting, urban landscape modeling lighting and home lighting system, solar LED lighting, but a higher one-time investment is the bottleneck in its development.
