In general terms, dimmers are devices that vary light level (intensity) of lamps by controlling the amount of power that is delivered to the lamp. Dimming can be controlled by either manual or ...
More than 105 million high-intensity discharge (HID) lamps, ranging from 20W to 2,000W in size, are now in use in a broad range of interior and exterior applications in the United States. HID lighting ...
The electronic ballast circuit block diagram (see Fig. 1) includes the ac-line input voltage (typically 220 Vac/50 Hz or 120 Vac/60 Hz), an EMI filter to block circuit generated switching noise, a ...
Designing Dimming Circuits for Fluorescent Lamps is a challenging task typically realized using a complex, high-pin-count control IC. Compared with non-dimming designs, dimming circuit ICs: Are more ...
