Recently the United States NASA's Harbert telescope has discovered “new earth”,which located in the Lyra constellation, more than 1200 light-years away from earth, we are always looking for “new earth”, I think we upset by our own living environment rather than curiosity to mysterious space! Is it true that the earth is really not suitable for human habitation? Obviously, now the earth temperature and environment is more and more abnormal, it is closely connected to human beings on the earth's environment destruction and plundering of resources. As we all know, the second industrial revolution has brought the rapid development of science and technology, while caused great damage to the environment of the people, especially the development of lighting industry brought environmental pollution and energy consuming! the incandescent lamp is mainly of the world lighting, but Australia have stopped production of incandescent lamp early in 2009, gradually banned the use of the traditional incandescent lamp in 2010, China ban 100W incandescent lamp sold in the market on last 1stOctober , as the world's most populous country ban method, the incandescent lamp has quit the stage of history, at the same time, other major energy-saving environmentally friendly LED lighting has shined with its unique advantages. Why did prohibit the use of incandescent lamps and promote the use of energy-saving LED lamp all the countries in the world? As everyone knows, the lighting principle is to transform electricity into light, only 10% of incandescent lamps electrical energy convert into light energy, the other is transformed into heat energy, and alternating current lead to light flashing phenomenon, when reflected in the case of voltage instability is most obvious,the visible light also have infrared, ultraviolet radiation ,all of these are harm to the environment and people's physiological, especially cadmium and other non-metallic contained in abandoned bulb pour into air and soil cause environmental pollution once again, there is no doubt that it bring a lot of negative to people's lives and the environment. In order to avoid these disadvantages we have made efforts to improve, and eventually the invention of energy-saving and environment-friendly LED emerge as time require! LED floodlights widely used in LED lighting adopt LED semiconductor lighting, LED semiconductor lighting electric energy can be converted energy into 100%, and the low voltage constant current drive convert the alternating current into direct current so that the light has not flashing phenomenon, stability light does not cause irritation of the eyes, and the light source is a high brightness COB integration, strong light and clear, this is why the LED floodlights has wider range and stronger light than others, so it can be used in outdoor lighting, such as square, parks, public. stadium, LED floodlights has good heat dissipation, strong adhesion, waterproof and dustproof structure characteristics, it spray electrostatic high heat dissipation material on surface, all these features ensure the LED floodlight expose and air?rain and fly dust in many outdoor environment and have long service life, LED floodlights is installed firmly and easily by screw, so save a lot of manpower and material resources, it is not easy to drop of damage, he can be used in few roads and railway tunnel. LED floodlights with its high energy conservation and environmental protection features and wide and bright light has been widely accepted by people, I believe, the world lighting will replaced by LED lighting in near future, then we don't have to worry about lighting brings us the pollution and damage to the environment, in the LED lighting and we can better comfortable for learning?work ?leisure and entertainment. When the night falls, colourful world make the earth more beautiful and romantic,we will love this planet at night, because he is more suitable for our living, it is because of the LED lighting, we are no longer struggled to research space for humans to live!
