Lighting And The Environment

In this nugget we will learn about the concepts of Lighting and the environment. The earth is heated by solar radiation, which passes easily through the atmosphere. This solar radiation heats the surface of the earth. As a result, the earth emits infrared radiation. Some of this infrared radiation is absorbed by the atmosphere, which prevents it from completely escaping into space. This causes a gradual warming of the earth’s environment. Carbon dioxide has a very strong absorbing effect. Increasing carbon dioxide emissions strengthen the absorption of infra-red radiation in the atmosphere. This is what causes the ‘greenhouse effect’. Power stations that generate electricity from fossil fuels are major emitters of CO2, the most important greenhouse gas Lighting accounts today for 19 per cent of all electricity used worldwide and is therefore responsible for a substantial part of CO2 emissions. Philips innovates lighting products that can generate more light with lower electricity. Energy Efficient lighting belongs to the best measure to lower the electricity consumption and thus CO2 emission. Philips also innovates to minimize or delete regulated substances. Compact fluorescent lamps have the lowest mercury levels and the latest LED lamps do not contain mercury. There is still 40% electricity to be saved if all customers buy the most energy efficient lighting. We then improve people’s quality of life, as well as the quality of the world we live in. thank you
