LED luminaires require precise power and heat management because LEDs convert most of the electrical energy they receive into heat rather than light. Without adequate thermal management, this heat can ...

This file type includes high resolution graphics and schematics. LED-based lighting is replacing incandescent and gas-discharge lamps in many situations. As practical lighting sources, and considering ...

A matrix of eight switches form an eight-channel LED bypass switching IC that controls on/off/dimming and fault indications for an LED array. In operation, the switch matrix interfaces with an ...

A while back, [Chris Lu] was studying how analog circuits, specifically op-amps can be used to perform mathematical operations and wondered if they could be persuaded to solve differential equations, ...

You’re undoubtedly familiar with the clip-on blood oxygen sensor and meter that uses a pair of LEDs and a photosensor. This non-intrusive transmissive-light device—which took decades to develop, ...
