The project can be used effectively to detect fast moving objects using sensors made from LED array. One of the slave microcontrollers (Slave A) is the PIC16F876A which autonomously scans the bottom ...

LumiBright UV boards, leveraging chip-on-board LED technology with metallic-core printed-circuit-board (PCB) substrates, feature a large emitting area using a closely packed array of UV LED chips to ...

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 team led by Prof. SUN Haiding from the University of Science and Technology of China (USTC) developed a vertically integrated micro-scale light-emitting diode (micro-LED) array，which was then ...

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, ...
