This Technical Briefing Note examines corrosion mechanisms common to electronic assemblies and summarizes conformal coating and potting technologies used to mitigate corrosive action in finished pico‐powered lighting assemblies.
This Technical Briefing Note identifies a few basic design steps and user instructions that can protect pico-powered lighting products from early failures caused by water ingress. The use of drip…
Lithium-ion batteries are cost-effective, high capacity, and capable of long cycle life when properly used in off-grid products. They can, however, present a serious safety hazard if poorly manufactured or…
This Technical Note is Part I in a series of Notes examining the environmental durability of pico‐powered lighting products. Ingress Protection (IP) ratings are covered as they apply to the…
This Technical Note discusses how solar module performance characteristics relate to off‐grid lighting systems and how to best assess module performance by measuring the current‐voltage (I-V) performance curve.
This document provides a list of proposed changes to IEC/TS 62257-9-5. We were interested in gathering feedback from stakeholders regarding our proposed updates and any additional updates they would suggest…
This Technical Note compares several existing and emerging lithium-ion battery technologies and provides an overview of the safety issues involved in designing products with lithium-ion batteries.
This Eco Design Note examines safety issues related to LED lights and the consumers who use them. Specifically, it explores three basic questions: Can off grid LED lights be too…
This Technical Note describes ways that sealed lead-acid (SLA) batteries can fail during storage and shipping and suggests steps that manufacturers can take to prevent damage to their SLA products…
…services to people living without access to electricity around the globe. Through our activities, including quality assurance work, market development, and policy advisory services, we have helped to enable off-grid…
