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 ...

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 ...

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 ...

Solar day lamps (SDL) are simple and cost-effective. A few examples of SDLs have been described in [1], [2] and [3]. An SDL without any energy storage element suffers from frequent changes in the ...

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, ...

All too often component manufacturers are the unsung heroes behind a great product. It's easy to recognize the brand whose name is on the box, but a large part of the work that goes into making a ...

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, ...
