5、LELED technology is finding widespread use in aviation applications. Given the significant differences between LED light sources and traditional technologies, developing successful products with LEDs requires a different design approach. This document provides general guidance on using LEDs. It ther

14、 design and installation of LED assemblies in aircraft. The use of “shall” in this specification expresses provisions that are binding. Non-mandatory provisions use the term “should.”1.1 PURPOSE The purpose of this SAE Aerospace Recommended Practice (ARP) is to recommend minimum design criteria whic

15、h will lead to adequate performance standards for LED products in and on aircraft. This document recommends design and performance criteria for developing products subject to CFR Parts 23, 25, 27, and 29 certification that use light emitting diodes (LED) as their primary source of light for luminanc

16、e and illuminance applications. It is intended as guidance for the certifying authority and lighting design engineers. This document includes but is not limited to commercial aircraft.2.

The metric involves several facets of color quality, including color rendering, chromatic di

47、scrimination, and observer preferences. Color Rendering Index (CRI): A metric used to evaluate the relative spectral content of a light source compared with a reference source. GENERAL LIGHTING: Diffuse lighting intended to illuminate a room or a space. GLARE: Undesirable light that interferes with the ability to see desired objects. L50%: The operating time in hours in the anticipated environmental and installation conditions that result in 50% of the initial lumens. L70%: The operating
