Reducing maintenance and improving safety for commercial aircraft can at times oppose each other. Advanced technologies in LED’s and Super-capacitors have the potential to reduce maintenance and improve safety for aircraft. By introducing LED’s and Super-capacitors the performance profiles of these technologies require a rethinking of the Lighting systems and equipment setups. Rewriting Lighting System requirements allow for greater design solutions which will provide better Lighting products to support operators which will in turn make them more profitable and improve safety over products that are flying today. Two examples are presented: an LED Landing Light and a Supercap based emergency light. 1) Aircrafts need adequate illumination for night time landing. Currently this requirement is met via high power halogen lamp or HID lights. Useful light for the pilot is a combination of intensity and direction. Too much light in undesired direction can cause excessive halation in adverse weather conditions forcing the pilots to shut down the lights entirely.

This SAE Aerospace Recommended Practice (ARP) contains methods used to measure the optical performance of airborne electronic flat panel display (FPD) systems. The methods described are specific to the direct view, liquid crystal matrix (x-y addressable) display technology used on aircraft flight decks. The focus of this document is on active matrix, liquid crystal displays (LCD). The majority of the procedures can be applied to other display technologies, however, it is cautioned that some techniques need to be tailored to different display technologies. The document covers monochrome and color LCD operation in the transmissive mode within the visual spectrum (the wavelength range of 380 to 780 nm). These procedures are adaptable to reflective and transflective displays paying special attention to the source illumination geometry. Photometric and colorimetric measurement procedures for airborne direct view CRT (cathode ray tube) displays are found in ARP1782. Optical measurement procedures for airborne head up displays (HUDs) can be found in ARP5287.

Automotive exterior lighting systems has several regulatory requirements & most of the manufactures have defined internal standards to achieve desired expectations based on vehicle category. Unavailability of such requirements for interior light illuminating systems has motivated the authors to generate test specifications & measurement methodology. There has been growing interest in automotive vehicle interior lighting for both functional and aesthetic requirements. The purpose of this study is to evaluate the Interior light illuminating devices in terms of “Light harmony”. The lighting harmony is “Maintain the color combination and light intensity level within users comfort zone”. In this study the lighting harmony is measured by means of two methods; one is Subjective evaluation & other is Objective evaluation. The details of these methods are discussed & the available results were analyzed to understand the acceptable limits of light intensity & color combination to achieve expected harmony.

The past decade has seen a revolution in automotive lighting, a sector that not only includes visible lighting today, but also illumination through infrared sources as lighting and driver assistance systems combine. The lighting industry as a whole has moved rapidly from simple incandescent and gas discharge based light sources to solid-state technology in the form of light emitting diodes (LED) and organic light emitting diodes (OLED). Moving to solid-state light sources brings a number of clear advantages, not least a significant reduction in energy use. Illumination has accounted for a significant proportion of energy use and a 50% reduction by 2025 over 2005, through the move to solid-state light sources, which is a significant achievement largely led by the automotive sector. Within the automotive sector, solid-state light sources allow an overall reduction in CO2 emissions, and light sources have a significantly longer working lifetime. Beyond the LED and close to production OLED light sources that are being incorporated in vehicles today, new light sources in development include digital micro-mirror devices (DMD) and laser technology.

Fiber optics has been a viable technology for data communication applications in many environments including aircrafts, providing higher bandwidth, longer transmission distances, EMI/RFI immunity, and lower weight than copper cables. Until recently however fiber optics was not a viable transmission medium to efficiently distribute light for illumination on aircrafts. Fiber optic lighting systems, referred to as the Remote Source Lighting technology have been installed on US Navy vessels including the LPD 17 class, the Italian Multi-Mission Frigate FREMM class, and the DDG 1000 class. Optical fibers can offer advantages over conventional lighting systems that use copper cables due to safety, lower maintenance, EMI/RFI immunity, no possibility of short circuits or sparks, lightweight, and low operating costs. Higher procurement costs, primarily driven by the 37 fibers optical cable, have prevented a broader usage on naval vessels and for other applications including aircrafts. Systems utilizing visible Lasers as light sources are being developed under a number of US Navy sponsored programs, enabling the use of single fiber cables to transport light.

Lighting and illumination systems using visible Lasers light sources are being developed under a number of US Navy programs to reduce the ship's costs including acquisition, installation, operation, and maintenance. Recent advances resulting from research initiatives funded thru the Office of Naval Research Mantech program and a Navy SBIR project are making broader applications of this technology feasible, including possible transition into aircrafts for position, landing, anti-collision, cargo loading, wing icing detection, and interior lights. The development of these lasers is being driven by the high definition projection industry, with substantial investments made to bring the technology to broad scale implementation, and with the anticipated increase in product availability and decrease in costs. The laser systems offer significant advantages over fiber optic systems using other light sources including metal halide and LEDs. A laser prototype has provided from a single fiber five times the intensity of an LED from a 37 fibers cable.

Highly transparent, UV and heat-resistant, yet flexible and injection-moldable - these are the characteristics of the new, heat curable liquid silicone rubbers (LSR) which supplement the range of established materials used in lighting applications. With the rapid developments seen in recent years in lighting technology, the classic material - glass - is facing increasing competition from alternative transparent plastics entering into applications such as light guides, primary optics and lenses. This field is dominated by materials such as PC, PMMA, COP and PMMI, offering advantages in molding and high degree of design freedom, glass does not have. The injection molding process is the key to cost effective manufacturing, particularly in the case of high-volume production. Other advantages over glass are a less tendency to crack and a lower component weight. However, thermoplastics are also subject to application-related limitations such as temperature or UV-light resistance. The new, highly transparent liquid silicone rubbers supplement the existing range of materials and offer special physical properties typical of a curing elastomer and these are described below next to possible applications.

Procedures may vary depending upon the type of display (for example, monochrome, color shadowmask, beam index, etc.), but all types are considered. This ARP describes the methods to be used in measuring those performance characteristics important for color and luminance use in direct view airborne electronic display systems.
