It’s not only a place to prepare and eat food, but also a place to relax, a place to entertain, and a place to enjoy. It should be inviting, bright, functional, and easy to control. The right kitchen lighting will help you stay clean, organized, and safe, while letting you create the perfect atmosphere for an early morning baking frenzy, board games with the kids on a rainy afternoon, or spending a couple’s night in. Most of all, light layering (having multiple light sources for different purposes) is the most important, all-encompassing rule in kitchen lighting design. A single light source never does any space justice. You need different sources of light for different purposes. Ambient lighting, task lighting, accent lighting, safety lighting, and mood lighting are all essential parts of great kitchen design. This book will first and foremost address task lighting in the kitchen. Under cabinet lights are the most popular, attractive, and handy kind of task lighting for the kitchen. Lighting designers agree that the path to any beautiful, functional kitchen starts with excellent task lights. Kitchen task lights have one simple purpose – to help you out.

  • City of Oakland Outdoor Lighting Standards
    CITY OF OAKLAND OUTDOOR LIGHTING STANDARDS PART 1: GENERAL The Public Works Agency (PWA) will continue to design, procure, install, maintain and operate the City street lights and pedestrian lights. The PWA-Electrical Services Division will enforce the Street Lighting Warrants (Warrants) and all Outdoor Lighting Standards (Standards) for City works and for private development projects on public right of ways or City properties. The PWA-Electrical Services Division will approve all street lights and outside area lighting design and specifications consistent with the Standards and the Warrants. 1.01 SECTION INCLUDES A. Lighting Level Standards The City of Oakland implements its street light level guidelines in the Warrants. These guidelines are in accordance with the Illumination Engineering Society (IES) lighting guidelines for all facilities, in the United States and worldwide. Adherence to the City of Oakland Street Lighting Warrants will have the effect of creating a more uniform light level, which will enhance visibility. B. Lighting Design Guide The Outdoor Lighting Standards will require a combination of good lighting design practice and energy- efficient, permanently installed lighting. Glare: Use house-side shields. Outdoor lighting design will not introduce glare to pedestrians and drivers alike. Safety: Safety lighting will be allowed for directional signs, stairs, steps, entrances and exits, walkways, roadways, parking lots, and other areas, which can be considered hazardous. Security: Security lighting will be allowed for entrances, vulnerable low window areas of buildings, fences, alleys, and excavation routes. Tree: Spacing from center of tree trunk to center of street light pole will be at least 20 feet. C.

  • Study of Museum Lighting and Design
    STUDY OF MUSEUM LIGHTING AND DESIGN Approved: ____________________________ Dr. Heather C. Galloway Director, University Honors Program Approved: ____________________________ Dr. Hegde Department of Family Consumer Science Supervising Professor STUDY OF MUSEUM LIGHTING AND DESIGN HONORS THESIS Presented to the Honors Committee of Texas State University-San Marcos In Partial Fulfillment of the Requirements For Graduation in the University Honors Program By Elizabeth Gay Hunt San Marcos, Texas May 2009 STUDY OF MUSEUM LIGHTING AND DESIGN ABSTRACT A museum is a place to discover, explore and learn about the past, present and future of creativity, as well as history. Lighting plays a significant role in developing interaction between humans and museum artifacts in one defined space. " Museums are places where lighting design is critical to the overall experience”(Lowe,43, 2009). Lighting is essential for human interaction in a space. Technical illumination research lays a foundation to conduct analysis in a variety of museums. This research component is significant to understand the complexity and various facets of overall museum lighting design. This study evaluates both the quantitative and qualitative aspects of lighting design in four museums. Psychological, physiological and experiential components are observed in these museums’ environments to analyze lighting design within its exhibits. My observations and knowledge gained by studying these museums help influence and enhance the design of the Cedar Hill Museum of History. 3 DEDICATION This Honor Thesis is dedicated in memory of my mother, Carolyn T. Hunt. She instilled in me the idea that we live a short time on Earth. She often said, “We are given talents that we must give back to the community and help others.” The Cedar Hill Museum of History lighting design is a reflection of how she contributed to the community of Cedar Hill and helped mold the community into what is today.

LAMPS’ reputation continued to grow as NASA chose James Carley to build To maintain its technical excellence in the special miniature lamps for the Apollo Space miniature lamps industry and continue to Shot, Voyager Probe and most recently the develop the company, James Carley expanded Space Shuttle. Carley Lamps enjoyed rapid Carley Lamps’ product range and introduced growth and success in the Aerospace industry high intensity miniature lamps to the flashlight in the 1970s & 80s. industry in early 1980. Today, in 1999, professional police, firefighters and special forces prefer and request Carley lamps for their flashlights and weapons mounted illumination systems. Carley Lamps is the largest producer of quality flashlight lamps in the world. In early 1990 Carley Lamps was approached to develop a high intensity medical lamp for a hand held Fiber Optic Laryngoscope. Curtis Carley, Carley Lamps Vice President developed and Craig, James, Curt and Suzy Carley patented the Mediflector® brand medical lamp. 1999 Carley Lamps Inc.

  • Final Report for Comprehensive Study on International Practice on Phasing out Energy Inefficient Incandescent Lamps
    Final Report For Comprehensive Study on International Practice on Phasing Out Energy Inefficient Incandescent Lamps Prepared by November 2009 EEExxxeeecccuuutttiiivvveee SSSuuummmmmmaaarrryyy � 1. As part of the Government’s ongoing efforts to promote efficient use and conservation of energy, the Government would like to keep track of the recent worldwide development on phasing out of inefficient incandescent lamps and switching to more energy efficient ones so as to reduce carbon emissions. The Government commissioned Hong Kong Productivity Council (HKPC) to carry out comprehensive fact-finding study to benchmark the overseas practices and the various options adopted in phasing out of energy inefficient incandescent lamps as well as the practices and approaches in the phasing out schemes of these overseas countries; and the availability of viable and efficient alternatives for different categories of incandescent lamps. This report details the findings of the study and provides an overview of the different phasing out schemes developed by various countries. It should be noted that as the phasing out schemes of overseas countries are still evolving, this report provides a snap-shot of the information available at the time the report is prepared. 2. Incandescent lamps are commonly classified in accordance with their functional and technological characteristics. The functional classification for incandescent lamps is based on whether the lumen output is non-directional or directional. They are commonly named as non-reflector type lamps (or called non-directional lamps) and reflector type lamps (or called directional lamps). On the other hand, the technical classification is based on the in-fill gas types of the incandescent lamps and operating voltage of the lamps.
