About This Item
IEEE P1789/D2, Sept 2014 is a draft recommended practice focused on modulating current in high brightness LEDs to help mitigate potential health risks to viewers. It addresses lighting design choices, drive-current behavior, and the relationship between LED modulation and human exposure. For engineers working with solid-state lighting, this technical document can help guide safer implementation and evaluation of operating conditions, especially where flicker or other modulation effects may be relevant.
What is IEEE P1789/D2, Sept 2014?
IEEE P1789/D2, Sept 2014 is an IEEE draft recommended practice intended to describe how current modulation in high brightness LEDs may be managed with viewer health in mind. It sits at the intersection of component behavior, circuit design, and lighting application engineering. The document is relevant to systems where LED output is intentionally varied, whether for dimming, control, or other operating modes. Its draft status indicates it was part of an ongoing technical effort rather than a finalized standard.
Where is IEEE P1789/D2, Sept 2014 used?
This document is most applicable in LED lighting development and evaluation, especially for luminaires, drivers, and control systems that use modulated current. It may be used by designers of commercial, industrial, and architectural lighting equipment, as well as by teams assessing flicker-related performance in electronics and power conversion circuits. IEEE P1789/D2, Sept 2014 can also support procurement and testing discussions when viewer comfort and exposure considerations are part of the specification.
Why is IEEE P1789/D2, Sept 2014 important?
IEEE P1789/D2, Sept 2014 matters because current modulation in high brightness LEDs can affect both lighting performance and perceived visual comfort. Using a recognized technical reference can improve design control, support more consistent testing, and reduce risk when specifying LED drivers or dimming behavior. For product teams, it provides a practical basis for discussing safety-oriented modulation limits and comparing designs more objectively. That can be valuable when consistency and viewer protection are part of the engineering requirement.
