IES Lighting Handbook 10th Edition: A Comprehensive Guide for Lighting Professionals

The IES Lighting Handbook is the most authoritative and comprehensive reference book on lighting. It covers all aspects of lighting design, application, and technology, from basic principles to advanced topics. The 10th edition, published in 2011, is the latest and most updated version of this classic work.

The 10th edition of the IES Lighting Handbook features:

• A new illuminance determination procedure based on visual age and mesopic adaptation

• In-depth coverage of sustainability practices, including daylighting, controls, commissioning, and energy management

• Updated chapters on lighting quality, visual perception, photometry, color, light sources, luminaires, and lighting calculations

• Convenient summaries of key information in tables and graphs

• Numerous examples and illustrations in full color

• Over 1000 pages of content and appendices

The IES Lighting Handbook is an indispensable resource for anyone involved in lighting, including practitioners, designers, architects, engineers, students, researchers, and educators. It is the official reference for the IES lighting certification programs and the basis for many lighting standards and codes. It is also a valuable source of inspiration and guidance for lighting design projects.

To order a copy of the IES Lighting Handbook 10th edition, visit the IES website or contact your local IES section.

Lighting Design Principles and Methods

Lighting design is the art and science of creating effective and efficient lighting solutions for various spaces and purposes. Lighting design involves both qualitative and quantitative aspects of light. The qualitative aspect focuses on creating a pleasing ambience and enhancing the aesthetics of the space. The quantitative aspect focuses on providing adequate and appropriate illumination for the tasks and activities performed in the space.

Some of the basic lighting design principles are:

• Maximize the use of daylighting: Daylighting is the use of natural light from windows, skylights, or other openings to provide illumination and reduce the need for artificial lighting. Daylighting can save energy, improve visual comfort, and create a connection with the outdoors.

• Match the amount and quality of light to the function: Different spaces and tasks require different levels and types of lighting. For example, a living room may need lower and warmer lighting for relaxation, while a kitchen may need brighter and cooler lighting for cooking. The amount of light is measured in lumens (lm), which indicate the light output of a lamp, and footcandles (fc), which indicate the light intensity on a surface. The quality of light is measured in color temperature (K), which indicates the color appearance of a light source, and color rendering index (CRI), which indicates how well a light source shows the true colors of objects.

• Install task lighting where needed and reduce ambient lighting elsewhere: Task lighting is focused lighting that provides higher illumination for specific tasks, such as reading, writing, or working. Ambient lighting is general lighting that provides lower illumination for overall visibility and orientation. By using task lighting where needed and reducing ambient lighting elsewhere, lighting design can save energy, improve visual comfort, and create contrast and interest in the space.

• Use energy-efficient lighting components, controls, and systems: Energy-efficient lighting components include lamps, fixtures, ballasts, drivers, and transformers that consume less energy than conventional ones. Energy-efficient lighting controls include dimmers, timers, occupancy sensors, daylight sensors, and smart devices that adjust the lighting according to user preferences or environmental conditions. Energy-efficient lighting systems include integrated design strategies that optimize the performance and interaction of all lighting components and controls.

Some of the basic lighting design methods are:

• Use LED light sources: Light-emitting diodes (LEDs) are solid-state devices that convert electricity into light. LEDs are more energy-efficient, durable, long-lasting, and versatile than incandescent, halogen, or fluorescent lamps. LEDs can produce a wide range of colors and color temperatures, have high CRI values, and can be dimmed and controlled easily.

• Use ENERGY STAR labeled lighting products: ENERGY STAR is a voluntary program that certifies energy-efficient products that meet strict performance criteria set by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE). ENERGY STAR labeled lighting products include lamps, fixtures, ceiling fans with lights, decorative light strings, exit signs, and more. ENERGY STAR labeled lighting products can save energy, money, and greenhouse gas emissions.

• Use outdoor solar lighting: Solar lighting is powered by photovoltaic (PV) cells that convert sunlight into electricity. Solar lighting can be used for outdoor applications such as pathways, gardens, decks, patios, fences, signs, security lights, and more. Solar lighting can save energy, reduce maintenance costs, and provide safety and security.
