Abstract

The radiant emission of a mercury-argon discharge in a fluorescent lamp assembly (10) is enhanced by providing means (30) for establishing a magnetic field with lines of force along the path of electron flow through the bulb (12) of the lamp assembly, to provide Zeeman splitting of the ultraviolet spectral line. Optimum results are obtained when the magnetic field strength causes a Zeeman splitting of approximately 1.7 times the thermal line width.

Energy efficient light bulbs: the magnetic arc spreading fluorescent lamp

Technical Report

The contractor developed an energy efficient light bulb based upon the spreading of the plasma via a magnetic field. A non-standard bowl-shaped lamp was designed, and, due to the large glass seal area, considerable difficulty was encountered in applying the phosphor and maintaining the low gas pressure. Thus, the performance data from these lamps could not be repeated. Data on the earlier double-cylinder lamps showed efficacies of 50 lumens per watt and were obtained by the application of the magnetic field. This magnetic arc spreading permits fluorescent lamps to obtain suitably high efficacies from lamp configurations other than the typicalmore »« less
Max Tech and Beyond: Fluorescent Lamps

Technical Report Scholand, Michael

Fluorescent lamps are the most widely used artificial light source today, responsible for approximately 70% of the lumens delivered to our living spaces globally. The technology was originally commercialized in the 1930's, and manufacturers have been steadily improving the efficacy of these lamps over the years through modifications to the phosphors, cathodes, fill-gas, operating frequency, tube diameter and other design attributes. The most efficient commercially available fluorescent lamp is the 25 Watt T5 lamp. This lamp operates at 114-116 lumens per watt while also providing good color rendering and more than 20,000 hours of operating life. Industry experts interviewed indicatedmore »« less

Occupational exposure in the fluorescent lamp recycling sector in France

Journal Article Zimmermann, François; Lecler, Marie-Thérèse; Clerc, Frédéric; ... - Waste Management

Highlights: • Chemical risks were assessed in the five fluorescent lamp recycling facilities. • The main hazardous agents are mercury vapors and dust containing lead and yttrium. • Exposure and pollutant levels were correlated with steps and processes. • All the stages and processes are concerned by worrying levels of pollutants. • We suggest recommendations to reduce chemical risk. - Abstract: The fluorescent lamp recycling sector is growing considerably in Europe due to increasingly strict regulations aimed at inciting the consumption of low energy light bulbs and their end-of-life management. Chemical risks were assessed in fluorescent lamp recycling facilities bymore »« less
