LED Lighting is a self-contained and introductory-level book featuring a blend of theory and applications that thoroughly covers this important interdisciplinary area. Building on the underlying fields of optics, photonics, and vision science, it comprises four parts: PART I is devoted to fundamentals. The behavior of light is described in terms of rays, waves, and photons. Each of these approaches is best suited to a particular set of applications. The properties of blackbody radiation, thermal light, and incandescent light are derived and explained. The essentials of semiconductor physics are set forth, including the operation of junctions and heterojunctions, quantum wells and quantum dots, and organic and perovskite semiconductors. PART II deals with the generation of light in semiconductors, and details the operation and properties of III-V semiconductor devices (MQWLEDs & microLEDs), quantum-dot devices (QLEDs & WQLEDs), organic semiconductor devices (OLEDs, SMOLEDs, PLEDs, & WOLEDs), and perovskite devices (PeLEDs, PPeLEDs, QPeLEDs, & PeWLEDS). PART Ill focuses on vision and the perception of color, as well as on colorimetry. It delineates radiometric and photometric quantities as well as various measures of luminous efficacy and efficiency. It also elucidates the significance of commonly used LED lighting metrics, such as the color rendering index (CRI), color temperature (CT), correlated color temperature (CCT), and chromaticity diagram. PART IV is devoted to LED lighting, focusing on its history and salutary features, and on how this modern form of illumination is deployed. It describes the principal components used in LED lighting, including phosphor-conversion LEDs (PCLEDs) for generating cool- and warm-white light, chip-on-board (COB) devices, color-mixing LEDs, LED filaments, retrofit LED lamps, hybrid devices, LED luminaires, and OLED light panels. It concludes with a discussion of smart and connected lighting that reviews plant-centric lighting and highlights the roles of gamma and circadian brain rhythms in human-centric lighting. Finally, the performance metrics for traditional and LED light sources are summarized. Each chapter contains practical examples, highlighted equations, color-coded figures, and an extensive bibliography.

SAFETY AND HEALTH FOR ENGINEERS A comprehensive resource for making products, facilities, processes, and operations safe for workers, users, and the public Ensuring the health and safety of individuals in the workplace is vital on an interpersonal level but is also crucial to limiting the liability of companies in the event of an onsite injury. The Bureau of Labor Statistics reported over 4,700 fatal work injuries in the United States in 2020, most frequently in transportation-related incidents. The same year, approximately 2.7 million workplace injuries and illnesses were reported by private industry employers. According to the National Safety Council, the cost in lost wages, productivity, medical and administrative costs is close to 1.2 trillion dollars in the US alone. It is imperative—by law and ethics—for engineers and safety and health professionals to drive down these statistics by creating a safe workplace and safe products, as well as maintaining a safe environment. Safety and Health for Engineers is considered the gold standard for engineers in all specialties, teaching an understanding of many components necessary to achieve safe workplaces, products, facilities, and methods to secure safety for workers, users, and the public. Each chapter offers information relevant to help safety professionals and engineers in the achievement of the first canon of professional ethics: to protect the health, safety, and welfare of the public. The textbook examines the fundamentals of safety, legal aspects, hazard recognition and control, the human element, and techniques to manage safety decisions. In doing so, it covers the primary safety essentials necessary for certification examinations for practitioners.

Light is the primary driving force for photosynthesis and thus dictates carbon assimilation, biomass production, and yield in plants. Light also plays an important role in a myriad of physiological and biochemical processes in plants, from eliciting specific gene responses to whole-plant phenomics. The lighting environment is especially important in controlled environment agriculture (CEA) as it supplements or fully replaces natural light to improve growth and quality. Due to the advancements in lighting technologies and the rapid growth of the CEA industry, lighting research has been propelled into the forefront of the plant science field. Unlike organisms in the animal kingdom, plants are sessile. The inability to move has forced plants to evolve mechanisms to deal with the lighting environment they are in. For example, in environments that are rich in far-red light, leaf expansion and stem elongation are promoted in an effort to orient themselves in a more advantageous position to absorb photosynthetically active radiation (PAR). We have yet to fully understand the physiological and biochemical implications of plants under all forms of light, from ultraviolet to far-red. The goal of this Research Topic is to collect studies which further our knowledge of how plants interact with their light environment.

This book states that the new environmental challenge will also have to be faced ethically, science can provide the tools, but people will have to be sensitized so that they make their own environmental ethics. The challenge of the new era is: the environment and therefore the climate, as it does not start outside of us, but as a constituent element of our life and therefore lived ethically. The new vision proposed in this book is to push technology together with the human being, in assuming environmentally ethical behaviors: this is the greatest collective action of humanity. Sustainable development has allowed an integrated key to the social, economic, and environmental dimensions. Through ethics, sustainability can be combined not only by referring to the problem of pollution and the exploitation of natural resources, but it creates a new global era that includes all dimensions of people's lives and of society. The shared and structured environmental ethics allow an approach that is no longer short-term but provide the collective tools to look far in time. With this book, we want to lay the instrumental, technical, social, and legislative foundations, to provide a new methodology for the care of the environment, as up to now, there has been much discussion, but little achieved in a truly ethical way.

This book presents an in-depth review of the recent interdisciplinary studies that have shed light on the mechanisms of the creation, energy transfer, and measurement of the dressed photon. A dressed photon is a type of photon that results from the interaction between light and matter in a confined space, typically on the scale of nanometers. It has been applied to nano-fabrication technologies, energy conversion technologies, and silicon light-emitting devices. Despite its extensive applications in various fields, the dressed photon's off-shell nature has posed challenges in describing it through conventional optical scientific theories. The book explains how, through a mathematical viewpoint, the underlying spatiotemporal vortex dynamics connect the dressed photon, the dark energy field, and the structure of the universe. The canonical equations of motion, which describe the time evolution of dynamical systems with Hamiltonian structure, play a key role in understanding these physical phenomena. In particular, the covariant form of equations of motion, where vortex tensors explicitly appear, corresponds to the transformed canonical equations of motion in the Eulerian representation. This newly augmented view of the equations of motion presents a deeper understanding of the interconnectedness of different physical phenomena, which can enlighten graduate students, junior scientists, and industry engineers engaged or interested in this field.

In this valuable reference work, Ichiro Fujieda focuses on the component technologies, device configurations, and operation principles of image acquisition and display technologies and provides detailed use cases to give practical guidance on the various current and potential future applications of these technologies. The technology and the physics behind these devices can be grouped into three categories: optical technology, material science, and semiconductor device technology. This book enables readers to gain an understanding of these three areas in relation to the flow of image information and several example applications of the technology. Fujieda first describes the building blocks of image sensors and displays (detectors, light sources, transistors, and wavefront control devices) and their configurations, operation principles, and characteristics. He then describes in more detail image sensor technology (including MOS image sensors, CCD technologies, and X-ray and infrared imagers) and displays (including thin-film transistor arrays, LCDs, OLEDs, MEMS devices, and more). Finally, he provides real-world examples of how these technologies are used together to give the reader an understanding of their practical applications and their potential use in future devices. Some important laws in optics and definitions in color science are included for easy reference. Through this approach, the reader will gain a detailed understanding of each of the component parts of existing imaging devices and will be able to apply this to future developments within the field. This book will benefit any advanced undergraduate and graduate student and industry professional who wishes to expand his or her understanding of the hardware handling digital images. Some basic knowledge is required on semiconductor device physics and the interaction of radiation with matter, though these are described in the appropriate sections.
