Abstract:
A universal lighting source controller including integral power metering for use with substantially all light source types including fluorescent, incandescent, magnetic low voltage, electronic low voltage, light emitting diode (“LED”), high density discharge (“HID”), neon, and cold cathode. The lighting source controller includes a line voltage dimming circuit that can control the intensity of light sources in a lighting circuit and measures the actual amount of power consumed by the light sources. The line voltage dimming circuit includes a triac circuit for controlling this intensity and current and voltage detection circuits for measuring the power consumption. The lighting source controller can also include low voltage dimming circuits to provide a control signal to light sources having electronic or magnetic dimming ballasts to set the intensity of these light sources.
A fluorescent lamp controller with dimming capability has its dimming function disabled for a given period of time, preferably about 100 hours, when new lamps are connected to a ballast to "season" the lamps by driving them at full rated current. The dimming function is restored after the seasoning interval has passed. An indicator is provided to inform the user that the seasoning function is in use.
In a relay switching panel, a switching circuit operates to selectively connect and disconnect resistive, capacitive and inductive loads to an AC power source with substantially no arcing. The switching circuit comprises a pair of relays, preferably connected in parallel, with one of such relays having a triac, connected in series therewith. With the relays open, an air gap isolates the power source and the load. In closing the relays in sequence, one relay provides a conductive path from the power source to the triac. After a suitable delay to allow the relay contacts to stabilize in the closed position, the triac is triggered to provide a conductive path from the power source to the load, and a large current surge flows to the load. After the current surge has subsided, the second relay is closed to provide a direct conductive path between the power source and the load. Next the first relay and the triac are removed from the circuit to ensure full conduction through the second relay.

International Classification:
H05B 33/08 G05F 1/12
Abstract:
A light fixture can include a lighting circuit comprising at least one light source and at least one discrete component. The light fixture can also include a power supply coupled to the lighting circuit, where the power supply provides a setting current to the at least one light source. The light fixture can further include a sensor that measures the setting current flowing to the at least one light source. The light fixture can also include a controller coupled to the power supply and the sensor, where the controller provides, in real time, a setting current correction signal to the power supply to adjust the setting current delivered to the at least one light source. The setting current correction signal can be calibrated to an actual value of the at least one discrete component of the lighting circuit.

Abstract:
A lighting system includes a plurality of light fixtures. Each light fixture includes a sensor for performing a test on the light fixture an generating test data. The light fixtures also include a hardware processor and a radio communication module. The radio communication module can communicate the test data to a mobile computing device or to a node. A diagnostic software application can receive the test data, identify a malfunctioning component, and order a replacement component.

Abstract:
A power distribution module (PDM) can include an input portion configured to receive high-voltage (HV) power from a power source. The PDM can also include a power transfer device electrically coupled to the input portion, where the power transfer device is configured to generate at least one low-voltage signal using the HV power. The PDM can further include an output section electrically coupled to the power transfer device and including a number of output channels. The PDM can also include at least one switch disposed between the output section and the power transfer device, where the at least one switch has an open position and a closed position. The PDM can further include a controller communicably coupled to the at least one switch, where the controller operates the at least one switch between the closed position and the open position based on a power demand measured at the output section.
