Morning News China a leader in LED lighting manufacturers , NVC (02222.HK) today officially signed with the OCA, the OCA lighting and services as partners. Experts said the move indicates that China has taken an international lighting company an important step in brand building.
Last July, authorities announced the "three years out of one billion incandescent light, while light 1 billion energy-saving lamps," the schedule. It is estimated that by 2015, LED lighting suppliers in China will reach 20% share, driven by industrial scale up to 500 billion yuan.

LED lighting technology development
LED lighting of the prospects
As the Earth's greenhouse gas emissions, a growing problem, approaching the critical point of the Earth self-regulation, countries have introduced policies, including our governments around the world need urgent implementation of energy saving (carbon dioxide), LED lamps are the most energy-efficient green electric light, natural lighting, energy saving as the main option, with the LED lighting suppliers cost and price decreases, the rate is accelerating its spread in 2020, LED lights will be more than 50% market share .
Reduce the cost of LED lights
LED chip occupies a major part of the cost of LED street lights, thereby reducing the LED is the main way to reduce the cost of the cost of LED chips.
LED chip technology is the key substrate and epitaxial growth technology. Sapphire substrate material from the traditional materials, silicon and silicon carbide, the development of zinc oxide, gallium nitride and other new materials. In a few years, including by means of chip architecture, the surface rough treatment and multi-quantum well structure design, including a series of technical improvements, LED in the luminous efficiency to achieve a significant breakthrough.
Low cost silicon substrate, technology advances, the luminous efficiency but also satisfied, if sustained, this growth rate, once you achieve a higher level, the silicon substrate as the main technical solutions become an inevitable choice, companies will huge economic returns.
Improve the light efficiency of LED lights
Improve the light efficiency can also increase effective from the ratio of light to start. Thin-film chip technology can reduce the loss of light output side, with the reflective surface of the bottom 97% of the light output from the front, making the energy conversion of light to be effective mostly light, not only significantly improve the efficiency of LED light bulbs, also for the lens design creates a superior convenience. Thin-film chip technology is ultra-bright LED chip production in the core technology.

10 Million yuan per year Ningbo support LED lighting item
Normal 0 7.8 磅 0 2 false false false EN-US ZH-CN X-NONE MicrosoftInternetExplorer4
It was learned that Ningbo Science and Technology Bureau and Ning bo Fiancial Bureau united draft a subsidy special funds management temporary measurement on semiconductor LED lighting manufacturer. According to the measurement, in 2011-2015, Municipal Fiancial Bureau will allocate 10 milllion yuan, and county、management committee arrangment relative budgeting and set up special funds which will be used for application item subsidy and promotion work.

LED bus stop lighting systems are particularly suitable for rural areas?
After nearly two years of the pilot, Hangzhou Xiaoshan region currently has 54 rural bus stop using solar power led lighting system. Xiaoshan passenger transport infrastructure headquarters confirmed that this lighting system is the latest in the next year before the Spring Festival, the region has completed the transformation of the rural bus stop in use.
Lighting system especially suitable for rural areasIt is reported that rural bus stop, no lighting, it is prone to the site to be touched or been touched Yexing Ren and other accidents. To some extent, bus stops lighting lighting even more important than the road. However, due to its location in rural areas, rural bus stop, take more trouble with the municipal people's power, then the cost of electricity is also high. Back in September 2008, Samick line Xinyi village bus stop on both sides of roads, installation of LED lighting systems, this is my first trial area LED lighting system. This lighting system consists of solar power and low-carbon of LED lights. Main function is to use photovoltaic technology to convert solar energy into electricity. LED is a semiconductor light-emitting diode abbreviation. In the LED lighting systems, photovoltaic electricity will be stored in batteries, then the supply of LED lights, complete with its light emitting characteristics. This system, solar energy is completely clean, light-emitting diode is an environmentally friendly, energy saving, power efficient solid-state light sources. LED lighting is the next generation of new sources of energy and the perfect combination. Xiaoshan passenger transport infrastructure Jin Wei, head of the command are said to use LED lighting in rural public transportation system not only solved the difficult problem of electrical connection sites, even more gratifying is that this system was originally designed for the 7th consecutive rainy days as usual to generate electricity. Last year, Xiaoshan nine consecutive rainy days, at night, bus stop lighting systems to work as usual. Stops in each province costs 3000 yuan
Jin Wei calculations are to reporters, the original bus stop site uses the fluorescent lighting. A 8 m bus station, for example, to install fluorescent tubes is 30, each fluorescent lighting 10 hours per night, the bus stops a year in electricity (commercial electricity prices) needs to 4489.5 yuan. Use of LED lighting systems, using solar power technology, no electricity costs. However, this system was the battery replaced once every three years, and to install security devices, this is a major expense. According to the staff, for this system is 12 volts, will not cause injuries to passengers. According to reports, the half of the transit site uses LED lighting systems, electric lighting, the other half still received the same time lighting, LED fluorescent lamp night power consumption of only about 30%. Year, the use of LED lights to save electricity bus station is about 3,000 yuan. It also is not fluorescent tube replacement cost. Fluorescent tube life is generally two to three years, the cost of each lamp to buy $ 8. The LED lamp life of 100,000 hours, according to the design for 20 years without replacement. LED Lights Lamp replacement cost is not generated by the number of pens. The end of September there are 580 sites, "light"
In the early 54 pilot rural bus stop in New Street and Town have a pilot up to justice, each with 10, Puyang, eight, six Canton Town, temporary Town, Nga town Ning around town all four, wearing the village and town on the river 2. It is understood that the end of September this year, 580 rural bus stops will be installed on the LED lighting system, until next year before the Spring Festival, the district soared to 600 rural bus stop, the cost savings will be considerable.
