绿色照明设计的若干思考 总被引：1，自引：0，他引：1
苏瑾 《福建工程学院学报》2005,3(6):655-657
绿色照明是国际公认的实施可持续发展战略的成功范例，但不能简单地理解为采用高效节能照明器材就是体现绿色照明，而是应在设计时树立照明大系统的观念，根据建筑环境的要求选择合理的照度标准，合理采用电光源、电器附件、灯具、配线材料，优化照明控制。文章同时阐明了在推进绿色照明设计时必须走出的几个误区。 相似文献

Studies suggest that the learning environment can act as a third teacher in contributing towards student academic success. A variable within the physical learning environment that has received little attention in the literature is the interior lighting. Because of budget constraints and age, most American public school classrooms have fluorescent lighting fixtures installed. A new lighting technology, Light Emitting Diodes (LEDs), is becoming popular in commercial facilities across the United States because of energy efficiency. Previous research has demonstrated that lighting influences adult worker productivity and mood in a workplace. However, because children process stimuli faster, it is unknown whether LED lighting would have the same influence in a learning environment. Researchers hypothesise that students display more engaged behaviours in classrooms lit with LEDs as compared with fluorescent lighting fixtures. The current study tested this hypothesis by observing child engagement behaviours in a pre-K classroom under LED lighting and fluorescent lighting fixtures to compare differences. Students displayed more engaged behaviours under the LED lighting condition.

近代骑楼商业步行街记载了城市的历史文化,既是人们夜晚休闲、游览、购物的活力地段,也是展示城市形象的重要窗口,其夜景规划要遵循“特殊性、功能性、艺术性” 的照明要求。针对骑楼照明现状和骑楼建筑及商业街的特征,要从“整体空间、历史建筑、景观要素”三个层面提出采用“分级分区”“分层就位”等照明方法,打造“整体协调、轮廓清晰、主次分明、重点突出”的骑楼夜景意象。最后通过厦门中山路商业步行街夜景观照明设计案例进行验证结论。 相似文献

Will student users prefer media presentation rooms specially designed, built, and equipped according to well-established and accepted environmental design and display system engineering principles to other, non-environmentally controlled media classrooms? The 503 university students questioned in this study did. The author concluded that given the proper instrument, students are capable of reliably evaluating factors in their learning environments — such things as acoustics, thermal conditions, visual display systems, and lighting — and that such factors are important to them. 相似文献

A small initial study aimed to find out what values, perceptions and attitudes educators from a sample tertiary faculty (the Faculty of Nursing at the University of Newcastle, New South Wales, Australia) have towards a group of new and emerging educational technologies. A questionnaire was formulated which was administered as a written survey or telephone interview. The study found that the respondents are most familiar with and have useful knowledge about CD‐ROM technology, and most are also familiar with video‐conferencing. These technologies are seen as the most potentially useful. Lack of knowledge, display/delivery equipment, and the time‐consuming nature of making such educational material are the major barriers which hinder their use of them. The study recommends further inquiry into the barriers that prevent the integration of such technologies into tertiary learning. 相似文献

While tertiary teaching staff are familiar with teaching strategies used in traditional course delivery, the design and delivery of courses integrating new technologies such as online materials poses new challenges for many. Hence, although technology may be used, its use is often at a superficial level, failing to have significant impact on teaching practice. Motivated by the authors' belief that the development of online learning materials is an endeavour aimed at improving the quality of the learning environment, this paper explores the experiences of several lecturers within Griffith University as they engage in the design and development of online materials as part of the university's flexible learning initiative. Insights into the experiences and perceptions of teaching staff developing online materials are used to highlight issues that can then be used to inform appropriate professional development support for tertiary staff. This in turn will enable the integration of technology into the learning environment to act as a catalyst for positive changes to teaching practice. 相似文献

学习是对现有知识结构的丰富和重构。丰富是现有知识对新知识的同化过程,重构则是概念改变,表现为理论的修正和改变。上述学习理论运用于教学中的一个重要方面就是设计和组织学习材料。学习材料具有多种形式,包含着与学习者固着观念相联系的同化点,能引发学习者的认知冲突,或显示新知识的特性导致概念改变,并且能提供新的情景便于学习者的知识迁移。因此综合设计和组织学习材料是促进学习者对知识进行有意义建构,提高其学习能力的关键。 相似文献

This article is based on a previous Spanish study, which aimed to analyze the existence of barriers and aid for 44 students with disabilities enrolled at University. A qualitative methodology was used to collect data. The results analyze both the support and the obstacles provided by new technologies, the opinion students have of technologies in education, and how they affect their academic lives. Some of the training requirements of the faculty members regarding the pedagogical use of these technologies are also described. The conclusions display the university as an institution with potential for improvement, where certain technological limitations persist, thus leading one to believe that as an institution, it must exercise self-criticism and implement measures to facilitate an inclusive education. 相似文献

目前夜间事故勘察车载照明多采用传统自适应灯光,存在照射范围有限且调节照明方向繁琐等问题。因此,基于视觉设计一种车载照明自动跟踪系统。使用视觉处理技术与双步进电机控制对车载照明系统进行改进,以增强车载照明智能化和灵活性。针对传统自适应灯光需人为操纵照射目标的问题,车载照明系统在运行时对红外光源（移动目标）进行图像检测,实时反馈拍摄图像中红外光源位置坐标,再根据位置坐标信息控制双步进电机,带动车载照明灯准确地照射到红外光源坐标位置。实验结果表明,该系统可快速检测到照明目标位置坐标,准确控制步进电机移动,可满足跟踪目标的要求,准确率达 95%。 相似文献

Virtual universities and virtual learning environments are becoming increasingly accessible to faculty wishing to develop Web-based courses. They can provide a convenient cognitive framework to assist educators in moving towards new technology-based teaching methods. The University of Strathclyde has developed a series of faculty development workshops based around the conceptual model of Clyde Virtual University (http://cvu.strath.ac.uk) in an attempt to promote cultural change within the institution. The virtual university, whilst providing examples of good practice in the use of the new technologies, is also used as a delivery medium for the courses themselves, and as a place where participants can communicate with each other and archive their own materials. This paper explains the necessity for such a conceptual framework to overcome barriers faculty face in developing Web-based materials. It describes the Clyde Virtual University and the way in which innovative approac hes to teaching, learning, and assessment in a virtual setting can aid the development of a fully professionalized teaching force in higher education. 相似文献
