| Summary: | 碩士 === 中原大學 === 電機工程研究所 === 97 === Lighting has been a major part of electricity consumption in Taiwan. According to the statistics, revealed in the Energy Audit Annual Report for Non-manufacturing Industries, 2008, lighting takes about 12% in the total annual consumption of electricity in Taiwan. The present researches on eletricity savings focus majorly on the improvement of air-conditioning, and on lighting is the second major.The total annual consumption of electricity in Taiwan is 229.8 billion KWH and the consumption in lightning is 26 billion KWH (2008), which takes a percentage of 11.3%, second to the consumption in air-conditioning. Although there has been a large amount of projects related to energy savings conducted during the past decade, they are aimed mainly in the improvement of air-conditioning. As for lighting, it seems not the major concern.
Due to the application of new technologies and the promotion of the ideas revolved in saving energy and natural resources, the improvement of lighting has achieved some siginificnet goals in the design and manufacturing of lighting equipment. The establishment of new energy-saving standards and related policies also increase the efficeincy in lighting.
In addition to saving energy, the quality and comfortablity should also be concerned during the process of designing and manufacturing lighting equipments. This report discusses some crucial aspects related to the deisgn and development of lighting systems.
This report, including 12 successful cases in saving energy and reducing energy consumption in lighting, suggests some possible ways to improve the efficiency of lighting. For example, replace the artificial light sources of low luminous efficiency with those of high luminous efficiency; use electronic ballasts rather than traditional magnetic ballasts; change old light tubes and clean the light equipment regularly to keep the tube working in a high-efficient situation. Moreover, it is a good way to save energy by using the natural sunlight during the daytime. There are also some devices that can used to improve the quality of light and reduce the consumption of energy, such as wide area switches, individual switches, timing controllers, photo sensors, thermostat switches, direct digital control (DDC)systems and two-way lighting control systems. With these technology, lighting can be more efficient
