LED专栏

有关LED的应用信息已越来越多,本刊以往曾多次发表这方面的内容给大家传递这样一个信息:需重新审视我们对照明的认识和对LED的认识,用LED做照明要有一个全新的观念和手法。这次我们再总结有些文章的观念,进一步说明它的特殊性。     

城市立交桥照明设计浅析

文章分析了城市立交桥夜景照明的设计原则和设计手法,从城市整体角度进行考虑,确定统一协调、重点突出的照明等级。根据立交桥不同的建造方法,以立柱、桥身、护栏、钢架、拉索、桥拱等结构部件作为照明对象,以光源色温、动态变化等作为情感表达手法,营造城市夜景照明的景观效果。     

城市夜景照明的分类处理技巧

一个具有良好照明的城市是一个安全的城市,能给城市的居民提供更多的安全感,同时它将为城市融入与日间不同的品质特征,给人以同物不同景的视觉享受。美好的城市照明无疑会吸引更多的参观者和游客,从而会给城市带来极大商业的利益。城市的照明有多种,我们可以大致将城市夜景照明分为道路照明、建（构）筑物夜景照明、广场照明、商业街照明、环境照明及艺术灯光等不同类型。 １、道路照明 在过去,城市中机动车交通照明在城市照明需求方面通常是被优先考虑的,这也是我们通常提到的功能性照明。为了使车辆夜间在道路上能安全迅速地行驶,…     

以人为本的学校：日本横滨Honggodai基督教会学校和幼儿园

总部位于美国的Heschong Mahone集团以研究日光照明对学生学习绩效的影响而闻名于世。2001年，Heschong Mahone集团代表加利福尼亚州能源委员会在学校开展了一项关于日光照明的分析，2003年，它又深入研究了教室里让人身体舒适的环境和学生学习之间是如何产生联系的。根据这些知识发现，一些设计师开始改变对学校照明的态度。这是一个好消息!现在有建筑师、照明设计师和研究人员已经着手收集关于这个主题的报道或者正在学习这一领域。     

大美绍兴 绍兴环城河灯光秀

随着照明和多媒体技术的发展，“灯光秀”这一艺术表演形式在欧美一些国家日益成熟和流行，取得了显著的社会和经济效益。     

舞台照明对景观照明的启示

彩色灯光、动感照明、刻画重点、隐蔽光源等舞台照明手法的应用为舞台照明注入了无限活力。而将实体的小舞台向人的视野这个虚拟的大舞台延伸,则给在景观照明中运用舞台照明手法的理念提供了可行性。本文试图从场景转换、重点刻画等舞台照明的核心出发,探讨舞台照明对于景观照明的种种启示。     

“2013职业照明设计师大会”黑暗艺术小组讨论成果之二——在照明设计中摆脱对黑暗的误解

黑暗艺术的目标是运用黑暗“来增强创造性自由和理性标准化之间的平衡”。我个人对博物馆照明的兴趣使得我非常熟悉创造性地运用黑暗的手法。鉴于展示照明可允许的照明级别受传统规定的限制,这意味着将环境照明降低到安全移动所需最低级别是达到展示效果的关键。但是这种方式又和照明标准相悖,这个问题之所以需要我们关注是因为这些标准通常都是理性的。     

Users' Needs Lighting, Start-Up Power, Transportation, Mechanical Utilities, Heating, Refrigeration, and Production

The needs for emergency and standby power to enhance industrial and commercial power systems are frequently left wanting due to ignorance of the needs or of the systems available to satisfy the needs. This paper discusses various situations which require or desire emergency or standby power and mentions suitable systems for each application. The areas discussed include lighting, start-up power, transportation, mechanical utilities, heating, refrigeration, and production.     

Grades, Quizzes, Motivation, and Computers

The following paper describes the use of a simple FORTRAN computer program that may be used to determine course grades. The program is based on processing a set of IBM punched data cards. Each card contains the name of a student and all of his grades, including the final examination grade. The program may also be used to predict the final examination grade, based on previous quiz grades, and then, in turn, to predict the final course grade. It is thus possible to use this program periodically throughout the entire semester in order to provide the student, as well as the instructor, with a measure of his progress.

Dual-rotor, radial-flux, toroidally wound, permanent-magnet machines

A novel machine family-dual-rotor, radial-flux, toroidally wound, permanent-magnet (RFTPM) machines-is proposed in order to substantially improve machine torque density and efficiency. After the principles of operation, configurations, and features are discussed, the machine design and optimization guidelines are given. A prototype has been designed, built, and tested. The measured torque density of the prototype, which well matches the design value, is almost three times of that of the induction machine with the same power of 3 hp and speed. Meanwhile the efficiency is still kept high and the material cost is kept low by using ferrite magnets. Three novel approaches are proposed to reduce the cogging torque in the RFTPM machines, whose validity is verified by finite-element analysis results and experimental measurements.     

A new soft-switched, thyristor-based, regenerative, quasi-resonant,current regulated inverter

A variety of soft-switching techniques have been proposed to reduce the switching losses and EMI problems that occur with higher switching frequencies in hard-switched converters. In this paper, a new, quasi-resonant, soft-switched, three-phase inverter is presented which uses 12 thyristors as the power electronic switches, and hence has potential for use in high-power applications. The converter is fully current-regulated, suitable for high-performance motor drive applications, and is capable of 4-quadrant operation to allow regeneration back into the DC supply. The operation and the control of the inverter are described in detail and simulation and experimental results are presented     

Industrial system grounding for power, static, lightning, andinstrumentation, practical applications

Practically every structural steel building erected for industrial use incorporates reinforcing steel bars installed in the concrete footings. This, without any additional effort, constitutes a grounding electrode. The quantity of electrodes is directly related to the building area. When the structural steel framework is erected and interconnected, these electrodes are also interconnected in a parallel arrangement. Similarly, high-voltage metal transmission towers are installed using a metal footing base embedded in a concrete filled hole. The four tower legs are effectively in parallel and offer an adequate low ground resistance such that additional electrodes are generally not required. This brings us to the main point: the reinforced concrete footings, reinforced concrete grade beams, and other reinforced concrete structures provide, with a little work, an effective, reliable, and cost attractive system grounding vehicle
