To comply with new laws on reducing energy usage, fluorescent and HID lighting systems — both examples of arc discharge lamps — have become more complex and varied in their performance. To understand ...

For the spectrochemical study of solid materials with a glow discharge, the Grimm lamp is the geometry of choice. In the late 1960s the initial design was created when Werner Grimm of RSV ...

Neon lights are that kind of nostalgic item that everybody seems to love. The neon lamp is a type of gas discharge lamp, they generate light when an electrical discharge travels through an ionized gas ...

Users can easily reduce energy usage with dimmers. Dimming technology has evolved considerably over the last decade, especially in the arc discharge lamp category. What began as a device for simply ...

DR. CLIFFORD C. PATERSON, director of the Research Laboratories of the General Electric Company, Ltd., has written an interesting review of the technical progress made last year in the development of ...

IN many of the long stretches of main roads between towns and villages the only practical way of lighting at present seems to be by means of the lamps on the vehicles. In a paper on “Electric ...

Another point to note: NEMA says dimming systems also may not be capable of maintaining sufficient sustaining voltage in the dimmed mode. This may cause premature lamp dropout and short life. In ...

HPS, or high-pressure sodium, bulbs are one of the most popular HID (high-intensity discharge) lamps in use today. Heavier in the orange-to-red wavelengths, HPS bulbs provide excellent spectrum for ...

In this article, we discuss the principle behind the functioning of glow discharge optical emission spectrometry, some of its practical applications as well as studies that have used the technology in ...

We have previously reported biological effects of photolysis products of liquid water by 163-nm photons. The photon source was an electrodeless discharge lamp containing bromine. Recent follow-up ...
