This battery level indicator offers (5) LEDs that light up progressively as the battery voltage increases. This is a update of the 24V Battery Level Indicator. While designed for 36V systems, it is ...
High-brightness LEDs (HBLEDs) are making inroads into more traditional lighting applications that include a dc distribution system (for example, 24-V MR-16 track lights). HBLEDs are more efficient, ...
A new generation of LED driver ICs, combined with brighter lower-power LEDs, are making it possible to improve the energy efficiency of LCD panel backlighting. The widespread use of notebook computers ...
