2. 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 ...

3. LED circuit - Wikipedia

   en.wikipedia.org/wiki/LED_circuit

   Drivers may be constant current (CC) or constant voltage (CV). 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.

5. Dimmer - Wikipedia

   en.wikipedia.org/wiki/Dimmer

   This unit is wired in series with the load. Diodes (D2, D3, D4 and D5) form a bridge, which generates pulsed DC. R1 and C1 form a circuit with a time constant. As the voltage increases from zero (at the start of every halfwave) C1 charges up. When C1 is able to make Zener diode D6 conduct and inject current into the SCR, the SCR fires. When the ...

9. Electrical ballast - Wikipedia

   en.wikipedia.org/wiki/Electrical_ballast

   A dimmable ballast is very similar to a rapid start ballast, except that the autotransformer is connected to a dimmer. A quadrac type light dimmer can be used with a dimming ballast, which maintains the heating current while allowing lamp current to be controlled. A resistor of about 10 kΩ is required to be connected in parallel with the ...
