Street Lighting: A (b)right choice for cities

Nowadays many of the people who live in cities and smaller towns see it as only natural for urban areas to be lit up, yet few of them are familiar with the history of urban lighting. The first time candle-lit lanterns were used to light up the streets during winter nights was in 1417 in London, with oil and gas lamps later invented to banish darkness from city streets. Real progress was made with the advent of electric lighting, but there have nevertheless still been gradual changes in the role of urban lighting since its introduction. Back in the 1930s, streets were mainly lit in order to make them safer for cars. By the 1980s, however, street lighting was also intended to improve security and help pedestrians feel safer. A modern trend is to focus heavily on the lighting of other urban areas in addition to conventional street lighting.

Backgrounds on Light & Health and how HealWell system benefits hospital patients and staff

Light affects human beings in a variety of ways: visually, psychologically and (photo-)biologically. Light’s most obvious effect on humans is in enabling vision and the performance of visual tasks. The psychological effects of light are related to the attractiveness, atmosphere and ambience of the environment (light intensity, intensity distribution, dynamic aspects, light color and color distribution within the field of vision) and they affect our mood, alertness, feelings and motivation.

Optimum Lighting Energy Savings with Addressable Dimming Controls

Buildings consume more than one-third of the total primary energy used in the U.S. About two-thirds of a building’s primary energy use is attributed to electricity. On average, lighting accounts for 30% of energy use in office buildings, and thus often dominates the opportunity for energy savings among all electrical systems. According to studies by Pacific Gas and Electric Company’s lighting team, and Lawrence Berkeley National Laboratory, advanced lighting controls in conjunction with various energy management strategies can typically yield a combined lighting energy savings of 40 – 80% in office buildings. The objective of this white paper is to substantiate and quantify the potential energy savings that can be realized through the use of addressable (digital) dimming lighting controls as opposed to conventional analog controls.
