An LED is commonly used as a "power on" indicator for many electronic devices. For the LED to produce discernible visible light in daylight, the forward-bias current needs to be in the moderate range ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

MR16 halogen lamps normally operate from a low-voltage AC source typically generated by a low-frequency AC transformer or by a high-frequency electronic transformer. In most MR16 applications, the ...

ANSAN, South Korea--(BUSINESS WIRE)--Seoul Semiconductor Co., Ltd. (KOSDAQ 046890), a leading global innovator of LED products and technology, announced that it has introduced high-power LED package ...

Scientists have been working for years to harvest the power of ambient radio waves to power small devices, and these days there is hardly a richer source of these signals than Wi-Fi networks.

LED replacement of incandescent lighting for residential use involves IC design that requires “penny pinching” to a degree not found in many other areas. LED-based bulbs that replace their ...

Researchers demonstrated a novel technique to efficiently convert ambient low-power radiofrequency signals into DC power. This 'rectifier' technology can be easily integrated into energy harvesting ...

The adoption of LEDs continues to expand across a variety of sectors, including automotive, agricultural, industrial, commercial, and outdoor lighting. The biggest growth drivers are their lower power ...
