Patent
Power control system for current regulated light sources
TL;DR: In this paper, a light emitting diode (LED) lighting system includes a PFC and output voltage controller and a LED lighting power system, and the controller advantageously operates from an auxiliary voltage less than a link voltage generated by the LEM power system.
Patent
Color variations in a dimmable lighting device with stable color temperature light sources
TL;DR: In this paper, a method and system allow a lighting device having light sources with multiple color temperatures to vary a color temperature of the lighting device in response to changing dimming levels.
Patent
Switching power converter control with triac-based leading edge dimmer compatibility
TL;DR: In this article, a triac-based dimmer is configured to phase modulate a supply voltage to the dimmer so that an output voltage has a substantially uninterrupted phase delay during each half-cycle of the supply voltage during the dimming period.
Patent
Lighting system with power factor correction control data determined from a phase modulated signal
TL;DR: In this article, the phase delay in one or more cycles of the phase modulated signal allows the power factor correction (PFC) controller to determine the peak voltage, which is a PFC control parameter used by the PFC controller to control power factor corrections and generation of a link voltage.
Patent
LED lighting system with a multiple mode current control dimming strategy
TL;DR: In this article, the active value of the LED current varies from a full active value to an intermediate active value as dimming levels decrease, where the controller duty cycle modulates an active value for a second set of levels.
