This SAE Aerospace Recommend Practice (ARP) is intended to recommend safety related best practices when using metal halides high intensity discharge (HID) lamps and power supplies in aircraft applications. The use of high intensity discharge (HID) light sources on aircraft has increased substantially in the past few years. HID light sources, like many other light sources, can potentially be dangerous if not used properly. This document addresses characteristics of HID systems that need to be considered for aircraft applications.

"The light sources chosen for special study were arc tubes through which a condenser was discharged. The discharge was initiated by an external control electrode. Tubes were made of Pyrex or quartz and had cathodes of mercury or nickel. Work was first done with mercury tubes at low pressures. Later, tubes were made having nickel cathodes and filled with argon. Tubes were tested to see at what voltage they discharged spontaneously one hence if they could be used with the 20,000 V power supply available. A 2500 V power supply was obtained for use with low voltage tubes. An integrating light output meter was constructed for measuring the light output of the tubes. Using this meter relative readings of the light output of tubes used under different conditions were obtained. Fine fibres were set up and illuminated in a manner reproducing conditions of cloud tracks in an expansion chamber. The fibres were then photographed to get an indication of whether the light sources would be practically useful, and of their effects on a photographic emulsion. Emperimental results indicate that low pressure arc tubes are not a practical means of obtaining high voltage operation, Mercury cathodes were shown to be little better than nickel ones in all types of tubes studied; and have the disadvantage of becoming dirty. In gas filled tubes having pressures of the order of a few centimeters of mercury, the light output is greatest when the bore of the tube is small.[...]" --

High intensity pulsed light (PL) is one of the most appealing non-thermal technologies, due to its short treatment time and its wide range of applications in the preservation of packaged and unpackaged food products, as well as non-preservation processes for the food industry, water disinfection and medical applications. This is confirmed by the large increase in research articles published on the subject over the past years, and increasing interest from food producers concerning the use of this technology. High Intensity Pulsed Light in Processing and Preservation of Foods is the first book specifically focused on PL technology in a convenient single-source volume. It offers an incisive view on the latest developments and advances in this exciting technology from the perspective of microbiologists, biochemists, food technologists, electrical, environmental and food engineers, and medical doctors. On completion, it will provide a comprehensive overview of this field, highlighting the positive aspects of pulsed light applications as well as discussing areas of weakness and future trends. The book first provides basic information on the need for food preservation, the decontamination problems faced by the food industry and the expectations of the consumers. The most appealing current and emerging methods are briefly described, providing a general review of the applications and the efficacy of conventional UV light for the purpose of inactivating microorganisms in the food and water. Part I follows the introduction and reviews the principles of PL technology as non-thermal decontamination methods of foods while also describing equipment for generation of PL, the main critical design factors and control parameters. It also deals with the potential safety hazards when treating foods with PL. Part II critically analyses and discusses the effect of PL on safety and quality of food products. It elucidates mechanisms of microbial inactivation, discusses critical processing factors, reviews current background on the inactivation kinetics of microorganisms and enzymes as well as the impact on bioactive molecules, nutritional properties and quality parameters in foods. The use of PL as part of a hurdle or minimal processing strategy in conjunction with other factors or techniques of preservation is also considered. Finally, the third part of the book describes applications of the PL technology past the food sector, such as for water disinfection and parts of the medical field as well as regulatory aspects. High Intensity Pulsed Light in Processing and Preservation of Foods is a valuable reference for members of both academia and industry who are interested in gaining wide and comprehensive knowledge of PL technology.
