A battery backup for the solar-mains hybrid lamp design that supplies a constant light output regardless of available solar ...

[Petteri]’s design delivers 3 mA to each of eight surface-mount LEDs (which he says is actually a bit too bright) for a total of about 20 hours from one alkaline AAA cell.

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 ...

The 2-MHz, dual 1-A (or more) buck LED driver demonstration circuit DC2424A features a high-efficiency, compact layout. It can be altered to power up to 30 V of LEDs per channel from a 34- to 36-V ...

The new product family offers four new CXA LED Arrays (CXA1507, CXA1512, CXA2520, and CXA2530) delivering different lumen levels in two packages and optical sizes (minimum 80 and 90 CRI available).

The vintage, TI-made TIL305 is a printed circuit board that clips into a DIP-14 socket. The LED array is 5×7 pixels, with an extra dot for a decimal point, set on a 0.05″ grid, and a ...

The PCB layout if using two 10 LED arrays This board uses two 10 LED bargraphs to make up the display. 20 LED arrays are available but are not suitable for this design. This board layout has two ...
