China released to phase out incandescent route map in October 2012, at that time, most people believe that the energy saving light will replace incandescent. Just six months later, the semiconductor lighting for a more energy efficient lamp has been entering a large scale into the market.

Spend $ 40 billion for LED Street Light lamps procurement users to provide 30% financial subsidy

The strength of LED lights energy saving are obvious: compared with the same brightness, the 3W LED energy saving lamps spent 333 hours to consume 1 kWh of the electricity, while the ordinary 60W incandescent spent 17 hours to consume 1 kWh of the electricity, the ordinary 5W energy saving lamps consume 1 kWh of electricity.  Moreover, the LED lamp life is 5-6 times than the energy-saving lamps. “If  you do not consider  material aging factors,an LED may be used more than 20 years.” BOE Technology Group Vice President Li said.

High efficiency led lighting technology and the products have matured. “12th Five-Year” period , the unit of Guangdong Province, mainland GDP carbon dioxide emissions decreased by 19.5%target. For this reason, Starting from March 1, 2012, all financial investment in Guangdong province develop lighting project, all public lighting shall be using LED lights.

March 20, 2012, organized by the Ministry of Finance, National Development and Reform Commission, Ministry of Science and Technology 2012 semiconductor lighting products, financial subsidies to promote the project” in Beijing,  mainland public tender, 110 companies from all over the world have nearly 300 bids representatives participated in the tender. China Development and Reform Commission has made clear that in 2012 the Chinese government will spend 40 billion yuan t0 the procurement of LED street lamp and to th30 percent of financial subsidies for the users of high efficiency led lighting.

The subsidy policy will not only boost the LED lighting market, but also stimulate the demand for civilian use LED lighitng. The insider believes taht the real start of the domestic LED high bay lighting market will commence later this year.

The reshuffle of Large international companies, mergers and acquisitions is inevitable, so LED small businesses is hard to compete.

As a barometer of the high efficiency led lighting industry, the Guangzhou International Lighting Exhibition of data also shows signs of this, according to the organizers of Guangzhou Guangya Messe Frankfurt Co., Ltd.General Manager Mr. Hu Zhongshun said, the exhibition held in this year will not only expand the scale of 220,000 square meters, and 500 well-known listed companies, have to snatch a large booth in preparation for the second half of the industry to warm up.

The South Korean government announced in 2015, will invest 3,000 billion Korean won (about $ 279 million) to support the research and development of light-emitting diode (LED Lights). Korea Ministry of Knowledge Economy said in a meeting of economic policy adjustment. In order to push the high efficiency led lighting integration and technology development of the LED, the budget support of the total amount of 3,000 billion Korean won will be allocated  in the next five years, and to prepare ,and prepare promotion the LED industry to leap forward support strategy.

Known to promote the  original core technology development and popularization of LED High Bay lighting in public institutions by the Ministry of focus investment
in the early 2009. A new policy is focused on how to merge the LED technology with existing industries innovatively such as lighting, medical, and other integration and create a more high value-added technology.

The South Korean government put forward that ensure the new market-driven competitiveness and the market creation and consumer reliability, constitute the three major policy task in a industrial ecology of virtuous cycle, the plan to promote high efficiency led lighting integration career to the world’s advanced position before 2015.

Knowledge Economy Ministry combine the LED with IT first, will ensure lighting system that is  by individual or central control energy conservation , with tailored lighting of users
psychologically and physically , sterilization and purification function lighting etc new markets competitiveness.

The South Korean government invest 3,000 billion won within 5 years.Separated from the original blue LED,from the diversification of the particular wavelength or full color products , and preparations for the activated LED Plant Factory, the intelligent car headlamp innovative LED industrial base of integration.The South Korean government is also planning to implement rules marked of lighting functions and system of Management evaluation results etc in 2011.

Convenient for consumers to identify products. Also induce a large, small and medium enterprises to strengthen cooperation , also plan to manage high efficiency led lighting Forum in 2011 and provide of the LED Experience Exhibition of  technical exchanges between enterprises ,so that can reduce the cost burden of SMEs in the LED lighting certification, structure for a virtuous cycle of industrial ecology   .

South Korean government will organize a organization that the tentative name is LED policy agreement ” to help Smooth cooperation of enterprises and develop LED fusion technology . Additionally plan to let 70% building of Sejong City adopt LED lighting. Make the Sejong City mold into the LED Street Lights city ,to invest 10 billion won (about $ 9.29 million )  in 2011 , 60% ​and scope lighting of the river, 16 reservoirs will be replaced of high efficiency led lighting .

Industry policy officials of Information and Communication Ministry, the Liu Xiugen said that if integrate the force of the government and industry ,in the market of LED lighting and the integration markets formally opened within 1 to 2 years  , Korea will be able to ensure the dominant position .

Have already said that the best LED dimming is a simple PWM generator PWM dimming using the PWM dimming can be installed in the wall switch, and then use a potentiometer to control the PWM dimming ratio in order to achieve. To bright light switch off, then you need to add a pair of lines. It is not compatible with the original wall of the high efficiency led lighting switch leads. The lead of the led high bay lighting technology switch is only 2, you can while dimming can switch. This advantage is difficult to be compatible. But actually, truly the most commonly used dimming lamps table lamp or floor lamp dimmer switch are installed on the power cord is not a wall, that just do not care to take advantage of the wall of the two leads. In other words, the tone of the PWM alone can be directly applied to Dimmable high efficiency led lighting.

 

Taiwan has a company launched four sections called the EZ-Dimming GM6182 switch tone light of high efficiency led lighting would be a good program. Only the use of ordinary light switch on the wall will be able to achieve the dimming, the first time open for all light, the second on 60% brightness, third on 40% brightness, the fourth open for 20% brightness. The advantage of this system can use an ordinary wall switch dimming. And the power factor more than 0.92. Did not produce interfering signals into account. The disadvantage cannot be continuous dimming. There are operational high efficiency led lighting problems.
