摘要： In a scanning backlight for an LCD display, several backlights (101, 102, 103, 10n) provide a precisely positioned dimming pulse corresponding to a transition point of the LCD screen. The dimming pulse must be variable with video synchronization frequency and dimming duty cycle, which is a performance intensive calculation. One microcontroller performing this operation is limited in scope. By using several ballast controllers (141, 142, 143, 14n), the solution is scalable, in that it is flexible if the number of backlights (101, 102, 103, 10n) changes. Additionally, by using several controllers (141, 142, 143, 14n), added functions can be performed by the ballast controllers (141, 142, 143, 14n).

摘要： Systems and methods are disclosed that facilitate switching a lamp ballast between DALI and analog control states as a function of control state information stored prior to the ballast being powered of and control information received by an interface circuit for the ballast circuit. A depolarization circuit is coupled to the interface circuit and ensures consistent polarity across a rectifier circuit regardless of the polarity of two control wires coupled to a miswiring protection circuit in the interface circuit. In this manner, a single interface circuit provides dual 0-10V analog and DALI control for dimming a lighting device regardless of whether a wall-mounted controller coupled to the interface circuit is an analog or a DALI type controller, thereby mitigating a need to switch out a ballast circuit coupled to the lighting device when changing between DALI and analog type controllers.

摘要： The embodiment disclosed herein relates to a lighting system that includes an auxiliary lighting circuit for use with an electronic HID ballast. The lighting system comprises a power supply configured to provide power to a high intensity discharge (HID) lamp via an electronic ballast and a ballast power sensing component configured to determine the amount of power drawn by the electronic ballast and to convert this power drawn by the electronic ballast to a scaled voltage that is representative of the power drawn by an HID ballast. A lamp driver component is configured to provide power to an auxiliary lamp via the same power supply when the scaled voltage reaches a triggering threshold. A voltage regulation component is configured to regulate the power delivered to the auxiliary lamp such that the auxiliary lamp power stays within a predefined range.

摘要： An interface circuit 10 for coupling a power supply 12 that includes a triac phase modulator 18 with a compact fluorescent lamp converter and lamp load 14. The circuit 10 rectifies the modulated power supply signal with a rectifier 24. A current flowing through a current limiting inductor 112 goes through either a reverse current blocking diode 114 to power the fluorescent lamp or through a transistor 116 to reset/discharge the triac phase modulator 18. Transistor 116 is controlled by an R-S flip-flop. The reset 120 of the R-S flip-flop is connected through a current threshold sensor formed by a pair of resistors 144, 146 and a transistor 142. A high duty cycle oscillator is connected to the set 124 of the R-S flip-flop. Large current variations in the triac phase modulator 18 are prevented by current flowing through transistor 116 when the current no longer flows through the diode 114.

摘要： A fill wave electronic starter 10 includes an input circuit 12 which delivers a rectified voltage to charging capacitor 28. During a first state, voltage on charging capacitor 28 is used to turn on switching circuit 30, whereby current is delivered to cathodes 56 and 58. When voltage on capacitor 28 reaches a breakdown voltage of diode 46, latch circuit 50 is placed in an on state causing capacitor 28 to discharge, turning off transistor 32. This action delivers a high-voltage lamp ignition pulse 62 to lamp 60 causing it to start. Current flowing through input circuit 12 maintains conduction of latch circuit 50, rendering a low impedance state which maintains MOSFET transistor 32 off, and starter 10 in a disabled state after initial pulse 62.

摘要： The present application discloses a method and apparatus for providing an isolated set point from an input signal. The set point can control the amount of power applied to a lamp via a lamp ballast. An AC output signal from the ballast powers a dimming circuit. The AC signal is coupled across an isolation transformer and subsequently converted into a DC signal. This DC signal is loaded by a variable resistor, which creates a voltage differential across the resistor. This voltage differential is then seen across DC input terminals of the ballast, and it is across the DC input terminals that the set point is created. By varying the value of the resistor, the ballast set point is varied ultimately changing the power that is applied to the lamp by the ballast.
