The International Commission on Illumination (CIE) discussed the quality of lighting and energy conservation in the 2010 World Lighting Conference held in Vienna, Austria. Among them, there are considerable views on the effective use of daylight-assisted lighting and the development of LED lighting technology.
According to the International Energy Agency (IEA), 19% of the global electricity consumption is used in lighting. With the advancement of energy-saving lighting technology, new lighting equipment can meet the lighting quality and energy-saving requirements. CIE believes that as long as the world can gradually update the lighting equipment, the saved energy is enough to make up for the current lack of power supply, and also save the construction of new power plants, while avoiding possible damage to the environment.
At present, among the global public buildings, 3/3 of the lighting equipment is still old products without power saving capacity, and only 4% is new lighting equipment with lighting control systems such as daylight sensors. If you can replace all of these 3/3 old products with energy-saving lighting equipment, you can save up to 4~70% of the power. Peter Dehoff, head of strategic lighting divisions at Zumtobel, a European lighting manufacturer, said that the smartest and most effective way to save energy is to use daylight. The intelligent lighting control system can automatically adjust the indoor lighting amount with the amount of sunlight, which can save up to 60% of the electricity compared with the traditional lighting equipment that cannot be automatically adjusted.
