摘要： A method for regulating the ignition voltage of a discharge lamp (1) and the corresponding electronic ballast circuit, wherein said discharge lamp (1) is supplied with AC operating voltage by a half-bridge inverter circuit comprising two transistors (Q1, Q2). The current flowing through one transistor (Q1) of said two transistors (Q1, Q2) is detected, and the detected current iscompared with a predetermined reference value. When the detected current exceeds the predetermined reference value, the driving period of said one transistor (Q1) is immediately terminated and the driving period of the other transistor (Q2) of saidtwo transistors (Q1, Q2) is started, and the driving period of said other transistor (Q2) is made to bethe same as the terminated driving period of the one transistor (Q1).

摘要： A ballast (100) for driving one or more lamps (121) includes a controller (111) and a current reduction circuit (140) for accelerating a controller reset. Upon detecting a fault, the controller (111) disables the ballast for a preset period of time, and resets. The controller (111) additionally resets when the ratio of a supplied second value to a supplied first value falls below a threshold value. The current reduction circuit (140) reduces the supplied second value in less than the preset period of time, such that the ratio falls below the threshold value and the controller resets. An emergency lighting system (201) includes the ballast (100) as a primary ballast (100), a backup ballast (200), and a primary power source (102). The controller (111) detects a fault if the primary power source de-energizes and the backup ballast (200) disconnects the one or more lamps (121) from the primary ballast (100). The current reduction circuit (140) accelerates the reset of the controller (111) when the primary power source (102) de-energizes.

摘要： An integrated circuit (IC12) with both ballast control and driver circuitry and power factor correction (PFC) control circuitry (Fig. 1). At the beginning of preheating, power is provided to the load circuit at a voltage below a voltage at which the lamp can ignite, and the PFC control circuitry can then bring the DC bus voltage up to its running value (Fig. 2). For this purpose, the PFC circuitry is enabled depending on the mode of the ballast control and driver circuitry (Fig. 2). The DC bus voltage is regulated at a lower loop speed when the lamp is running than when the lamp is ramping to ignition, to alleviate DC bus drop. A criterion is applied to determine whether over-current detect signals indicate an actual fault (Fig. 2). For this purpose, detect signals during ignition ramping can be counted and compared with a fault number.

摘要： An electronic ballast circuit (15) for powering a gas discharge lamp (26) is networked with other ballast circuits to provide large scale lighting control on a local or remote basis. The ballast has an interface (10) connectable to a standard PC (20) for receiving commands and obtaining query information. The ballasts can be controlled individually or in groups. The ballast control also can download lighting profiles to a microcontroller in the ballast, and can support lighting control protocols including the DALI standard.

摘要： A ballast controller integrated circuit which executes a specific set of instructions via an integrated state diagram architecture to control a fluorescent lamp or high intensity discharge lamp and protect the ballast. The state diagram architecture (Fig. 2) controls powering up and down of the IC (2) and the half-bridge circuit (6, 8) driven by the IC (2), preheating and striking of the lamp (4), running of the lamp (4), sensing for numerous possible fault conditions, and recovering from these fault conditions based on the normal maintenance of the lamp (4), while requiring fewer internal and external components than previous electronic ballasts.
