Abstract: A system to identify incidents associated with streetlight fixtures based on sensor data from one or more smart sensor devices. Each smart sensor device is coupled to a respective streetlight fixture and captures data from one or more sensors. The data from a single smart sensor device or a plurality of smart sensor devices is aggregated to generate a current data signature of the one or more smart sensor devices. The current data signature is compared to a plurality of known signatures to determine if an incident associated with a streetlight fixture has occurred. Such incidents can include a failed light source, a failing light source, a weather incident, a geologic incident, etc. Depending on the type of incident an instruction is sent to the one or more smart sensor devices to perform one or more responsive actions.

Abstract: There is provided in combination with a rapid-start series-sequence type ballast for two low-pressure mercury discharge lamps, apparatus for reducing the power consumption of both lamps. The apparatus utilizes switch means in conjunction with a capacitor to limit the current supply to the lamps after the lamps are energized. The switch means has two members in series circuit arrangement with one of the electrodes of one of the lamps. Each member is connected on opposite sides of the electrode. The capacitor is connected in parallel circuit arrangement with one of the members. Initially upon energization the switch means has a low impedance state to permit current flow and then switches to a high impedance state. The switch means permits preheating of the electrode and thereafter upon response to current flow switches and causes the lamp current to pass through the capacitor and thereby decrease by a predetermined amount the current through the normally operating lamps. The switch means may comprise switch members having a positive temperature coefficient of electrical resistance.

Abstract: In the system disclosed, a transformer connected to an alternating power source establishes a continuous alternating output voltage which is connected directly across a gas discharge lamp to apply the voltage continuously across the lamp. The transformer output voltage is set within a range which includes a condition that causes the lamp to exhibit a positive impedance value when the lamp is discharging. The transformer and the source together exhibit an impedance substantially less than the impedance value of the discharging lamp.

Abstract: A high intensity lamp dimming circuit in which the lamp or lamps are placed in series with a pair of reactive elements, one of which is at least partially bypassed when the voltage across the element and the current through it are of the same polarity. The relative time of the bypass determines the amplitude of the lamp current and hence its brightness. A control network, isolated from the power lines to which the lamp network is connected, controls the timing of the bypass. This control network preferably uses a programmable unijunction transistor and operates on a low-level dc setting. The control circuit design permits ready connection to single phase and three phase power systems alike.

Abstract: A semi-conductor switch interrupts the flashtube current, thereby terminating the flash when a blocking voltage is applied to its anode. The blocking voltage is derived from a capacitor. If the capacitor has not sufficiently recharged following a previous flash, the semi-conductor switch is not completely blocked causing it to burn out. Therefore, a transistor is provided whose emitter-collector circuit short-circuits the ignition capacitor when conductive. The base of the transistor is connected to the charging circuit for the capacitor furnishing the blocking voltage in such a manner that the transistor remains conductive until the capacitor charging current has decreased to a predetermined current.
