Green lighting leads the world

Although the lighting industry accounted for only a small proportion in the whole economic structure, but in the cause of environmental protection has played an important role. 20% of the world's electricity is consumed in lighting, and about 40% of the electricity is consumed by old-fashioned incandescent bulbs. In the case of the same amount of light, energy saving lamp is not only less than incandescent lamp power 75%-80%, and the service life of the latter 10 times. If the world has replaced the old incandescent bulbs, you can save 7 tons of greenhouse gas emissions by reducing carbon dioxide each year.

Therefore, green lighting has become an important topic in today's world. In the just concluded 2007 Hongkong International Lighting Exhibition, the exhibition organizers not only devoted a piece of "green lighting", displaying the latest environmentally friendly lighting technology, also organized three green lighting technology around the theme of the seminar.

Dimmable energy-saving lamps are the future trend

In the context of environmental problems, energy crisis, carbon dioxide emissions, global warming, land pollution and other issues have become the factors that affect the world political and economic pattern. In recent years, the European Union, Australia, the United States, Canada have legislation to promote the development of environmental protection, including one, that is, in a specific period of time to fully or conditionally restrict the use of incandescent bulbs.

At present, the more mature alternative to incandescent bulbs is energy-saving lamps. In recent years, the rapid development of energy-saving lamp technology, many previously considered impossible to achieve the technology, has now been able to achieve one by one, which is expected to be more than the energy-saving light dimming technology.

Mann Camry is one of Hongkong's best-selling brand of energy-saving lamps, and its senior manager of Hongkong City, Wu and filial piety is the keynote speaker of the Hongkong lighting exhibition seminar. Wu Xiao and think, the traditional energy-saving lamp has a shape is not beautiful, larger size, a single color, flashing light, not enough light and other deficiencies. If the number of switches too much, the actual life of energy-saving lamps will be reduced.

At present, the traditional adjustable light energy saving lamp must be installed on the specific electronic ballast.

But the latest technology invention, so that an ordinary energy-saving lamps also have the effect of dimming. The latest adjustable light energy saving lamp is the dimming device embedded in the bulb, do not need to install additional devices, just by the switch control, you can achieve the effect of dimming.

In practical applications, this new type of dimmable energy-saving lamps, with a lot of advantages. Users can adjust the brightness according to the requirements of different occasions, in order to create a suitable atmosphere. For example, the elevator, usually can increase the brightness of the lamp in order to achieve the effect of lighting, and late into the night, you can put the brightness to the minimum in order to achieve the effect of energy conservation.

Rapid development of LED Technology

German Timon Rupp has more than 10 years of experience in the Asian LED market, currently OSRAM Asia LED marketing director. Timon has replaced the traditional light source with innovative LED solutions, and now his primary goal is to establish a solid state lighting system LED technology in the general lighting market in asia. As one of the keynote speakers seminar, Timon LED believes that although the development is along the wafer, the package to the LED luminous body integrated chain steady progress, but there are still many technical problems need to solve.

Timon said that in the past, due to technical limitations, the role played by LED is just decoration, but in the future LED will be used as a light source, and will gradually replace the traditional light source. The latest LED combines the advantages of traditional sodium lamp, metal halide lamp, energy saving lamp and other light sources, and has the advantages of high light efficiency, low energy consumption, long service life, safety and the like. More importantly, LED does not contain mercury and lead, waste does not pose a hazard to the environment, is a very good green light.

From Indonesia, the lighting industry has 27 years of experience in the Indonesian Chinese Nam was taken to retain the attitude of LED. Nam has been tracking LED technology for 5 years, he believes that the current LED is just a light signal, not a pure sense of light. In terms of stability or lighting effect, LED can not replace the traditional light source, so it can be applied to outdoor decorative lighting.

Wary of China's "green lighting" misunderstanding

This exhibition seminar another speaker, Professor Xu Shuyuan of City University Hong Kong Department of electronic engineering, made a review of energy saving and environmental protection "lighting cited in the keynote speech. Professor Xu reminded that China is currently caught in a misunderstanding of green lighting".

Professor Xu believes that China's lighting industry "green lighting" concept has been too much emphasis on the application of energy-saving, while ignoring the environmental pollution problems caused by scrapped lighting products. In fact, energy conservation can only reduce carbon dioxide emissions, but the environmental hazards caused by abandoned lighting products are far greater than the harm of greenhouse effect.

According to Greenpeace, the production of electronic products in the world each year about 2000 to 50 million tons, and electronic waste scrap was mostly shipped to developing countries, including 70% to the China. There are three main types of electronic waste, computers, batteries and lighting electronic products.

These electronic wastes cause great pollution to the environment. An electronic energy-saving lamp can only be used for two years, but the toxic chemical components, such as mercury and lead, will pollute the environment for thousands of years. Energy saving is not equal to 'green'
