  • Design and Radiation Tests on a LED Based Emergency Evacuation
    Design and radiation tests on a LED based emergency evacuation directional lighting PoS(TWEPP-17)092 Juan Casas CERN-TE/CRG 1211 Geneva 23, Switzerland E-mail: [email protected] Nikolaos Trikoupis1 CERN-TE/CRG 1211 Geneva 23, Switzerland E-mail: [email protected] A LED (Light Emitting Diode) based directional lighting system has been designed to indicate the best evacuation direction for applications like the Large Hadron Collider (LHC) tunnel. The design includes constraints for redundancy required by safety systems and for components selection by radiation effects. Most of the literature for radiation effects on LEDs concern digital communications systems, although some recent reports do exist for visible spectrum power LEDs and the reduction in light output versus dose is coherent with the results presented in this paper. Prototype lighting units were irradiated in CERN’s CHARM facility up to a Total Integrated Dose (TID) of 870 Gy and no failures were observed. This paper describes the basic design, presents field tests and the effects of radiation on the LEDs luminance.

    ARTICLE V. TURTLE NESTING PROTECTION Page 1 of 6 ARTICLE V. TURTLE NESTING PROTECTION Sec. 46-201. Purpose and intent. The purpose of this article is to reduce the impacts of artificial coastal lighting on threatened and endangered sea turtles that nest on the beaches of Miami Beach by restricting artificial lighting and other activities that disorient turtle hatchlings, causing them to crawl toward land rather than toward the ocean. This article is intended to provide overall improvements in nesting habitat degraded by light pollution, and increase successful nesting activity and production of hatchlings. The restrictions and constraints of this article shall be effective within the incorporated areas of Miami Beach and apply to any coastal lighting or other activity that has potential to adversely impact sea turtles within city limits. (Ord. No. 2006-3525, § 1, 9-6-06) Sec. 46-202. Definitions. The following words, terms and phrases, when used in this article, shall have the meanings ascribed to them in this section, except where the context clearly indicates a different meaning: Artificial light means any point source of light emanating from a device made by humans, including but not limited to incandescent mercury vapor, metal halide, sodium lamps, fluorescent, flashlights, spotlights, streetlights, vehicular lights, construction lights, security lights, bonfires, or any light emanating from any reflective surface of the device. Beach means that area of unconsolidated material that extends landward from the mean low- water line of the Atlantic Ocean, to the place where there is a marked change in material or physiographic form, or to the line of permanent vegetation.
