英国《新科学家》杂志曾预言,在不久的将采,传统的灯泡和灯管都将被白色LED取代。专家预期,在2007年左右,LED将开始逐步取代传统照明光源。这个预见很快的得到了事实的印证。今天,LED技术攻关和产品研发正在受到世界各国的高度关注,并已成为中国21世纪技术发展的一个重点攻关方向。 相似文献

道路照明节能是一个系统工程,是要在满足照明质量和视觉环境条件的要求下实现的节能,因此不能单纯依靠降低照明标准来实现节能的目的.而是要提高整个照明系统的节能能力。在达到照明标准和满足功率密度限值的前提下,通过提高照明设计水平、灯具和电器效率、减少灯具用量和降低灯具功耗来实现节能的目的。 相似文献

Electric lighting consumes 19% of total electricity production worldwide. Open-plan offices constitute the majority of office stock, in which most office workers perform their daily tasks, and hence the lighting in those offices has significant impact on, not only energy usage, but also occupants’ productivity. This paper presents a unique lighting optimization approach for open-plan offices that is capable of tuning task lighting to each occupant's preference in the most energy-efficient fashion. Exploiting individual controllability of the advanced networked lighting systems, each luminaire can be dynamically actuated at a different level to realize various lighting configurations without any physical rewiring. This research formulates lighting actuation into a linear programming problem and finds the optimal light outputs for each of the luminaires that collaboratively deliver specified lighting to each workstation while using the least amount of energy. Simulations using our lighting optimization approach have shown its versatility in providing proper workstation-specific task lighting under different requirements compared to business-as-usual practices. Energy savings are generated from tuning the light levels to occupants’ needs as well as keeping unoccupied areas unlit or minimally lit with this approach. 相似文献

A method of determining the depth of an area where one can turn off electrical lighting to utilize daylight in perimeter areas has been developed for standard offices with side-lit windows and typical artificial lighting. A graph of cumulative occurrence rates of the unobstructed sky illiminance is combined with the various distribution curves of daylight factors on the working planes in the standard rooms through the intermediary of the required illuminance. This graph makes it possible to decide the depth of the area easily and quickly by considering room widths, window-width ratios and obstructed angles of buildings opposite to the window across the street.Several limitations to this method are discussed and the problems for future research outlined. 相似文献

The reactions of 26 subjects to the thermal environment in a commercial building throughout the working day have been monitored for one year. This paper describes the instrumentation and the results obtained from the survey. The results show that each category of the Bedford comfort scale does not cover equal temperature intervals; the central, comfortable, category being more than twice as wide as the others. The preferred temperature of the occupants of the building was 22.0 °C which is in fairly good agreement with that predicted by Fanger's comport equation (22.6 °C). Away from the region of the optimum thermal environment the difference between the comfort equation and the survey results was much greater. If, as a design criterion the ,aximum number of complaints that would be acceptable from the occupants of a multi-occupancy office is 10%, the survey shows that the temperature throughout the office should be within the range 20–23 °C. The paper compares the reaction of the subjects during the summer and winter and morning and afternoon and that between males and females. Also investigated was the difference in clothing habits between males and females throughout the year. 相似文献

This paper examines the statistical properties of occupancy in single person offices of a large office building in San Francisco. A probabilistic model to predict and simulate occupancy in single person offices is proposed. It is found that vacancy intervals are exponentially distributed and that the coefficient of the exponential distribution for a single office could be treated as a constant over the day. Occupancy intervals are more complex than vacancy intervals. The distribution of occupancy intervals is time varying. Variations among different offices are examined. The implications of the findings on thermal and air quality control are discussed. 相似文献
