Most signal and marking lighting devices have light sources (bulbs), which can be based on either filament or LED technology. To assure field replacement, it is important that light source types employed be readily available in normal service channels. This document defines the...
This Standard specifies the method for obtaining the luminous quantities such as CIE averaged LED intensity and total luminous flux, and the quantities concerning the light source colour of white light emitting diode (LED) packages for general lighting. The photometry of light sources...
This Standard specifies the methods for obtaining the total luminous flux and the quantities concerning the light source colour of white light emitting diode (LED) modules and LED light engines for general lighting (hereafter referred to as the light source under test), using an...
This part of ISO 13207 specifies the characteristics of LED (Light Emitting Diode) lamps used as direction indicators when optionally monitored. It applies primarily to those lamps which are installed on 24V truck/trailer combinations. It will enable lamp-failure detection of LED...
This Standard specifies the measuring methods of luminous quantity of lamps for general lighting such as total luminous flux and luminous intensity, and quantities related to the light-source colour. This Standard is also applicable to the photometry of bulb-type LED lamps. See JIS C...
This SAE Aerospace Recommended Practice (ARP) establishes design and qualification guidance for interior aircraft lighting replacement of incandescent, halogen, or fluorescent light with LED lights.
A practical introduction to state-of-the-art freeform optics design for LED packages and applications By affording designers the freedom to create complex, aspherical optical surfaces with minimal or no aberrations, freeform design transcends the constraints imposed by hundreds of years of...
This Approved Method describes photometric testing procedures and reporting guidelines for reflector type lamps and LED based lamps that mimic this traditional style of lamp. The application of the described procedures and guidelines will improve reproducibility within a laboratory, and will...
This document is applicable to filament lamps, discharge lamps, LED light sources and LED packages to be used in road vehicles, i.e. in headlamps, fog-lamps, signalling lamps and interior lighting. It is especially applicable to those lamps and light sources which are listed in IEC...
IEC 60598-2-17:2017 specifies requirements for stage, television, film and photographic studio luminaires (including spot and floodlighting projectors) for use outdoors and indoors, with electric light sources on supply voltages not exceeding 1 000 V. This second edition cancels and replaces the...

This Standard describes a system of nomenclature that provides designations for envelope shapes used for all electric lamps. This system is shown in customary (inch-based) units and SI (metric-based) units. These envelope shapes are intended to be used with ANSI Standardized base and holder systems...
This Japanese Industrial Standard specifies the performance requirements, test methods and test conditions of self-ballasted LED-lamps of over 50 V to and including 250 V in power supply voltage that is used for household use or similar general lighting, and is integrated with a device that...
