2. LED circuit - Wikipedia

   en.wikipedia.org/wiki/LED_circuit

   In CC drivers, the voltage changes while the current stays the same. CC drivers are used when the electrical load of the LED circuit is either unknown or fluctuates, for example, a lighting circuit where a variable number of LED lamp fixtures may be installed. As an LED heats up, its voltage drop decreases (band gap decrease [1]). This can ...

   For each class the efficiency is defined for a rated output range from 0.75 to 375 kW. In the European Community the IE2 class is mandatory for all new motors since 16 June 2011. The IE3 class will be mandatory from 1 January 2015 (7.5–375 kW) and 1 January 2017 (0.75–375 kW).

4. Class-D amplifier - Wikipedia

   There were subsequently rapid developments in MOSFET technology between 1979 and 1985. The availability of low-cost, fast-switching MOSFETs led to class-D amplifiers becoming successful in the mid-1980s. [1] The first class-D amplifier based integrated circuit was released by Tripath in 1996, and it saw widespread use. [2]

5. Display driver - Wikipedia

   It was the first intelligent LED display, making it a revolution in digital display technology, replacing the Nixie tube and becoming the basis for later LED displays. [ 2 ] In the early 21st century, display driver chips are widely used for mobile displays in smartphones and other smart devices as well as larger flat-panel displays .

7. 0-10 V lighting control - Wikipedia

   en.wikipedia.org/wiki/0-10_V_lighting_control

   Dimming fluorescent ballasts and dimming LED drivers often use 0–10 V control signals to control dimming functions. In many cases, the dimming range of the power supply or ballast is limited. If the light output can only be dimmed from 100% down to 10%, there must be a switch or relay available to kill power to the system and turn the light ...
