This Japanese Industrial Standard specifies the measurement methods for the lumen maintenance factor and the chromaticity change of a white light emitting diode (LED) for general lighting. This method is also applicable to LED luminaires. NOTE 1 There are an LED package,...
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...
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...
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...
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 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...
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...

PURPOSE Following test specification determines the requirements which must satisfy motor vehicle bulbs. In general the determinations of DIN-sheets of DIN 72601 and of the ECE-regulation 37 - bulbs - , which are stated in the table 11.1 for the individual lamp types and additionally...
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...
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...
Light Emitting Diodes (LEDs) are no longer confined to use in commercial signage and have now moved firmly, and with unquestioned advantages, into the field of commercial and domestic lighting. This development was prompted in the late 1980s by the invention of the blue LED, a...
This standard applies to all local and formal investigations that are led by Network Rail. Purpose To provide a consistent, comprehensive and structured process for Network Rail led local and formal investigations.
INTRODUCTION Solid-state lighting using light-emitting diodes (LEDs) is set to radically alter the profile of the lighting industry, and has the potential to deliver substantial energy savings. A US study has predicted that, by 2027, solid-state lighting will constitute nearly half...
This TI applies to the replacement of conventional SL35 or SL18 lamps and ER with an LED SL35 module and dummy ER by staff holding Signal Maintenance Testing competence. Purpose This TI mandates the process to be applied when installing LED SL35 modules and associated dummy ER units....
