The scope of this paper includes dimmable fluorescent ballast and Light Emitting Diode (LED) drivers that are controlled by 0-10 V (1-10 V) control input. This paper explains the relationship between the control input voltage and overall energy consumed by these ballasts and...

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 the...

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....

This standard provides specifications for and operating characteristics of non-integral electronic drivers (power supplies) for LED devices, arrays, or systems intended for general lighting applications. Electronic drivers are devices that use semiconductors to control and...
