Low-voltage LED fixtures are commonly used due to their safety and cost-effectiveness. SELV standards define safe voltages for human contact, making such fixtures suitable for damp locations and areas accessible to children. Applications include architectural and track lighting, which benefit from smaller fixture sizes. Power over Ethernet enables efficient power and control in smart lighting systems.
How to use Hall-effect sensors: This guide covers the differences between reed switches and Hall sensors, the principles behind Hall-effect operation, and how to connect analog and digital Hall sensors in circuits. It includes a step-by-step process for assembling a magnetic polarity detector using digital Hall sensors.
Low-voltage DC lighting allows LED fixtures to be powered with a simple resistor instead of a complex driver, which improves safety and reduces component costs. Where is this applicable? How does this relate to solar panels and batteries? Using 48V DC grids, as practiced in India, enables efficient and safe lighting solutions.
