  • First off, it’s all about the lumens. Lumens are the visible light given off by a source, and they are the ultimate goal. Wattage has often been confused with lumens, thanks to how incandescent bulbs are rated (everyone knows that a 60W bulb is not as bright as a 100W one), but more efficient lighting technologies have greatly changed the relationship between wattage (essentially power usage) and lumens (light output). For example, an incandescent might operate at about 12-15 lumens-per-watt (lm/W), while an LED bulb will be in the range of 40-50, a much greater luminous efficacy...

  • Distribution in the Body proceeds rapidly, because the absorbing surface is greatly enlarged due to the formation of the epithelial brush border (submicroscopic foldings of the plasmalemma). The absorbability of a drug is characterized by the absorption quotient, that is, the amount absorbed divided by the amount in the gut available for absorption. In the respiratory tract, cilia-bearing epithelial cells are also joined on the luminal side by zonulae occludentes, so that the bronchial space and the interstitium are separated by a continuous phospholipid barrier.

  • The International System of Units (SI) will be used throughout this book. Four basic quantities and their SI units are listed in Table 1-1. The other three basic quantities and corresponding SI units, not shown in the table, are temperature in degrees kelvin (K), amount of substance in moles (mol), and luminous intensity in candelas (cd).

  • Colour image processing is divided into two main areas: full colour and pseudo-colour processing. In the former group, the images are normally acquired with a full colour sensor such as a CCTV camera. In the second group, a colour is assigned to a specific monochrome intensity or combination of intensities. People perceive colours that actually correspond to the nature of the light reflected from the object. The electromagnetic spectrum of the chromatic light falls in the range of 400-700 nm.

  • Booklet 1 of the licht.de series of publications is intended for all those who want to delve into the topic of light and lighting or wish to familiarize themselves with the basics of lighting technology. It also forms the introduction to a series of publications designed to provide useful information on lighting applications for all those involved in planning or decision-making in the field of lighting. One of the principal objectives of all licht.de publications is to promote awareness of a medium which we generally take for granted and use without a second thought.

  • There is a simple recipe for preventing accidents: see and be seen. But vision is a complex process. Road lighting needs to take account of that. Daylight illuminance ranges from 5,000 to 100,000 lux (lx). On a moonlit night, it reaches 0.25 lx at most. The fact that we can “see” over this vast brightness range is due to the eye’s ability to adapt.

  • Light sources should be as small as possible, produce light efficiently and have a long life. The demands of architects, light planners and operators of lighting installations have formed the basis of the research and development work of the lighting industry. Today more light sources with these properties are on the market than ever before in the history of artificial light. Until now, however, no filament or discharge lamp has combined all three properties. Only light emitting diodes (LEDs), also called light diodes, achieve this.

  • In this article we track four such trends over time. First, and following filmscholars (eg, Bordwell 2006; Bordwell and Thompson 2004; Salt 2006; 2009), we measure the average shot lengths of films and find that the changes seen in our filmsample are consistent with what they have reported. Second, we review and add to the data of Cutting et al (2011b) on the increase in the amount of motion and movement in films. Third, we measure the motion andmovement within shots of different lengths and find a reliable change in pattern. And finally, we measure the luminance of each film.

  • The SLL Lighting Handbookhas been written to forge a link between them. It is designed to be complementary to the SLL Code for lightingbut to go beyond it in terms of applications and background information without getting into the fine detail of the Lighting Guides. The SLL Lighting Handbookis intended to be the first-stop for anyone seeking information on lighting. It is aimed not just at lighting practitioners but also at lighting specifiers and students of lighting. For all three groups, we have tried to make it comprehensive, up-to-date and easily understandable.

  • PHOTOMETRY AND COLORIMETRY Chapter 2 dealt with human vision from a qualitative viewpoint in an attempt to establish models for monochrome and color vision. These models may be made quantitative by specifying measures of human light perception. Luminance measures are the subject of the science of photometry, while color measures are treated by the science of colorimetry.
