There have been major qualitative and quantitative changes in outdoor lighting technology in the last decade. The level of skylight caused by outdoor lighting systems is growing at a very high rate, about 20 percent per year nationwide. In addition, the spectral distribution of man-made light pollution may change in the next decade from one containing ...

We need artificial light in our daily lives, but we can have too much of it. Light pollution might be defined as excess artificial light, in the wrong place at the wrong time. Awareness of the problem, in Australia and elsewhere, has been growing since the previous edition of this Note.

AbstractRather than being complementary, street lighting and facade lighting are typically designed independently of each other. As a result, light from street lighting luminaires might spill onto building facades and influence characteristics of the facade lighting including required light levels and color.

On-premise commercial sign lighting and light pollution
LEUKOS The Journal of the Illuminating Engineering Society of North America, 2005AbstractThe present study explored light pollution as it may be produced by on premise identification signs. More than just “storefront” signs, on premise identification signs can also be found on the property of professional offices, financial institutions, corporate headquarters, governmental agencies, and medical offices.

Light Pollution – “Borders” of Lighting Design
2019 Second Balkan Junior Conference on Lighting (Balkan Light Junior), 2019History, especially the latest, shows that every human activity is in a state of development. At a certain point however, that development begins to move out from the socially acceptable norms. Often the developing process of lighting technology passes the reasonable limits. The megalomania manifests itself in the light sctattering and the uncontrolled

Urban Lighting, Light Pollution and Society
European Planning Studies, 2015The well-known satellite images of the earth at night, showing networks of luminous infrastructures expanding along the face of the earth, create a mosaic of light and dark spaces.

Sky glow presents itself as a background luminance over the sky, against which the astronomical objects are to be observed. The interference of astronomical observations is caused by the resulting reduction in luminance contrast. A value that is often used for the practical minimum of the natural background radiation is 21,6 magnitude per square ...

In general, the term “light pollution” or “light smog” refers to the excessive brightening of the night sky by artificial light (see Dark Sky). Street luminaires, billboards, shop windows and similar lighting installations that are switched on overnight produce light that reaches the atmosphere directly or indirectly (through surface reflections).

This paper begins by reviewing skyglow around major urban areas and the problem it creates for various segments of society. It further discusses the multiplicity of uses and users that must be considered in any control measures and remedies that are proposed in the interests of astronomy and conservation.
