  • Publication number: 20160073473
    Abstract: Dimming or illumination control of an LED-based lighting fixture can utilize a combination of pulse width modulation and constant current reduction. A light emitting diode driver can implement pulse width modulation to control light over a first light intensity range and constant current reduction over a second light intensity range. The first light intensity range can be less intense than the second light intensity range. Thus, the driver can practice constant current reduction for dimming at higher light intensities and pulse width modulation for dimming at lower light intensities.

  • Publication number: 20150349535
    Abstract: A distributed low voltage power system is disclosed herein. The system can include a power source generating line voltage power, and a first line voltage cable having a first line voltage end and a second line voltage end, where the first line voltage end is coupled to the power source. The system can also include a first power distribution module (PDM) comprising a first power transfer device and a first output channel. The system can further include a first LV cable having a first LV end and a second LV end, where the first LV end is coupled to the first output channel of the first PDM. The system can also include at least one first LV device operating on the first LV signal, where the second LV end of the first LV cable is coupled to the at least one first LV device.
