A lighting control system is coupled to one or more ballast/drivers operating one or more light sources. A low power control module receives analog, digital and/or DALI signals from one or more sources, processes the signals to provide an appropriate lighting response and outputs one or more commands related to light output of the one or more ballast/drivers operating one or more light sources. A gateway component receives wireless signals from the low power control module to relay to one or more control components. The control components provide instruction to modify the light output of the one or more ballast/drivers operating one or more light sources based at least in part upon the one or more commands received from the low power control module and/or the gateway component.

An apparatus for improving the performance of flashlights includes a substantially cylindrical housing () having a first end () and a second end (). A battery cap () is operatively connected to the first end of the housing and functions to secure a series of batteries in place. A series () of light emitting diodes (LED) () are mounted within the flashlight housing at the end opposite the battery cap. The series of LEDs form an LED array which operates as the light source for the flashlight. A substantially cone-shaped optical assembly () extends outward from the second end of the housing and operates to focus and disperse the LED beam emitted by the LED array. The flashlight further includes an adjustable switch () disposed on the exterior of the housing. The switch is coupled to a variable resistor () which permits control over the light level and/or battery life. An electronic current regulator (), enclosed by the housing, allows the LED beam to remain at a constant and desired light level, thereby increasing the efficiency of the battery life. A dynamic pulse control system () is coupled to the switch which takes advantage of the human eye perceiving the pulsed beam to be continuous. The pulse control also increases the peak current through the LED source.

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. The resonant inductor and resonant capacitor are selected to set a magnitude, and resonant frequency, of a bidirectional current in the lamp. 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.

An auto-starting lamp system comprises an electrodeless high intensity discharge lamp of the type including an arc tube that contains an ionizable fill, an excitation coil surrounding the arc tube for exciting an arc discharge in the ionizable fill at least during steady state lamp operation, and a starter circuit for facilitating arc discharge of the ionizable fill. The system further comprises a controllable r.f. power source for powering the lamp excitation coil, and an electrical network for matching the impedance of the excitation coil to the impedance of the r.f. power source. The impedance-matching network has the same impedance-matching relation during both lamp start-up and steady state lamp operation. A system controller causes the r.f. power source, during lamp start-up, to ramp up in power to a peak level preferably substantially in excess of a steady state lamp operating power level, and then to decrease from the peak level. Preferably, the system further comprises circuitry for re-powering the starter circuit after a predetermined period of time has elapsed that is sufficiently long as to prevent thermal damage to the lamp resulting from powering the starter circuit. The system preferably further comprises control circuitry for alternately turning on and turning off power to the starter circuit after the lamp ionizable fill recovers an ability to reach full arc discharge after being extinguished.

A low voltage DC input ballast circuit for a discharge lamp particularly suitable for a central lighting system includes an input filter stage which feeds into a first boost converter circuit controlled by way of a pulse width modulator device. The first boost converter provides warm-up and steady state run signals to the lamp in a voltage fed manner over a coupling circuit using components which are reduced in size relative to conventional discharge ballast circuits. Control circuitry provides various monitoring functions, an example of which is that, in the event of a low input voltage, the lamp will operate in a dimmed or faded manner rather than maintain lumen output by drawing additional current. A second boost converter circuit is associated with a starter circuit arrangement and operates such that starting pulses can be generated and repeated if necessary in a very rapid manner.
