Abstract: An ignitor and ignitor monitoring device is provided which is externally and detachably mounted to a high intensity discharge (HID) luminaire. The ignitor monitoring device provides a visual indication of whether or not the ignitor of the lamp in the HID luminaire is functioning. If the lamp is not on and the indicator is activated, sufficient open circuit voltage is present to operate the ignitor, the ballast in the luminaire is most likely functioning properly, and power is present to operate the luminaire. A service person can assume that the lamp is defective and can replace the lamp as a first attempt to correct the problem with the luminaire. If the lamp is off and the indicator is also not operating, the luminaire is not operating for any of a number of reasons such as a defective ignitor, a defective ballast capacitor, a defective lamp or loss of supply voltage from the power source. A service person can replace the ignitor in a first attempt to repair the luminaire. Replacing the ignitor is the simplest initial repair option since the ignitor is externally mounted on the luminaire.

Abstract: A gas discharge lamp ballast with an indicator of operability of the ballast is disclosed. The ballast circuit comprises circuitry for providing a d.c. bus voltage on a bus conductor with respect to a ground, and a resonant load circuit. The resonant load circuit includes lamp terminals for connecting to a removable gas discharge lamp, a resonant inductor, and a resonant capacitor.

Further included is a converter circuitry, including first and second serially connected switches coupled between the bus conductor and the ground, and providing to the resonant load circuit, at a node coupled between the first and second switches, a voltage that alternates between first and second voltage levels. Circuitry for generating first and second switch-control signals for alternately switching into conduction the first and second switches, including circuitry responsive to a feedback signal representing a current in the resonant load circuit, are further included. The ballast circuit, moreover, includes overload detection circuitry for detecting if voltage applied to the lamp terminals exceeds an overload level; and circuitry for indicating, in response to such an overload condition being detected by the overload detection circuitry, probable operability of the ballast circuit.

Abstract: Remote controllers, positioning systems, and methods configured for the efficient assignment of addresses in a coded lighting positioning system are proposed. Particularly, a proposed remote controller comprises a receiver for receiving coded light from a light source in a coded lighting positioning system, where the coded light comprises an initial light source identifier of the light source. The remote controller also comprises a processing unit for assigning a modified light source identifier to the light source based on the received coded light, and a transmitter for transmitting the modified light source identifier to the light source. The modified light source identifier is a locally unique identifier used to provide positional information.

Abstract: Wireless lighting control systems and methods for controlling the illumination of one or more light fixtures are disclosed, including power loss detection of hardware. Embodiments include a zero-cross detection circuit including a timer, the timer reset by a zero-cross detection, and the zero-cross detection circuit detecting a loss of power of the AC supply upon the timer reaching a preset time without resetting. Embodiments further include a first voltage regulator having an input coupled to the AC supply and an output providing a first DC supply. Embodiments still further include a wireless transmitter having a power input, the wireless transmitter for communicating with at least one other component of the wireless device control system. The first capacitor provides energy storage sufficient to power the wireless transmitter for a duration long enough to transmit one message upon detecting the loss of power of the AC supply.
