Abstract
That greenhouse gas (GHG) emission causes ¡§Global Warming¡¨ is a human common problem today in the earth. The GHG emission will gradually promote our weather temperature and change which we must pay for a lot. For example, the warming temperature will dissolve icebergs, that it will elevate the sea level. Also, our land area will decrease. If climate zones were shifted, it would be possible to initiate some animals migrate. In the worse case, our living space will be squeezed and some special diseases will be spread out¡Ketc.
In view of environmental protection awareness in every country, we must face the problem and crisis which comes from ¡§Global Warming¡¨ and ¡§Heating Pollution¡¨. In June of 1992, there was a meeting in Rio of Brazil. All representatives who comes from 153 different countries sign an agreement ¡V the United Nations Framework Convention on Climate Change (UNFCCC). They try to stabilize greenhouse gas concentrations at a level that would prevent dangerous interference with the climate and environmental system. To achieve this goal, the Kyoto Protocol was adopted on COP3 in December 1997 to place legally binding limits on GHG emissions. This Protocol norms 38 countries and European Union. In June 2007, the Group of Eight (G8) have reached a consensus and expect in year 2050, CO2 emissions can be reduced to the half of current emissions. We can see that, every country is vigorous to look for alternative energy that eliminates the environment destroyed and saves the earth resources. For example, Solar Energy, Water Energy, Wind Energy, Biomass Energy, Ocean Energy and Geothermal Energy¡Ketc. Those are gradually developed and applied in our daily life.
My research is focus on the LED applications based on the substitution of traditional lighting. Actually, LED has all advantage of the energy saving, eco-lighting and economy of scale. How to use this alternative lighting is of great urgency and the major topic in light source manufacturers. For example, if America can replace their 55% white heat bulbs and 55% fluorescent lamps by LED before 2010, they can save 35 billion US dollars every year. For Japan, if they replace 100% white heat bulbs, they can save one to two of Nuclear Power Plants. Also, they can save above 100 million of gasoline every year. As to Taiwan official estimation, we can save 11 billion electricity degrees every year when we replace 25% white heat bulbs and 100% fluorescent lamps. That electric power is approximate to save one Nuclear Power Plant and 50 million of gasoline every year. According to the data above, the population of LED will give us a lot of eco-benefits. My report leans on researching and treating LED. Then, I take one step ahead to demonstrate how important it is to apply LED on our human light source and the effects of earth environment.
