摘要： A PUR circuit for generating a reset signal includes a first node for receiving a reference voltage and a second node for receiving a supply voltage that is referenced with respect to the reference voltage. The circuit further includes a voltage level detector coupled between the first node and a third node, the voltage level detector being configured to generate a first control signal at the third node. The voltage level detector includes a first transistor having a first threshold voltage associated therewith. A resistance element is coupled between the second node and the third node, the resistance element having a first resistance value associated therewith. The circuit also includes an inverter having an input coupled to the third node and having an output for generating a second control signal in response to the first control signal. The inverter includes a second transistor having a second threshold voltage associated therewith which is lower than the first threshold voltage. The voltage level detector is configured such that the first control signal is substantially equal to the supply voltage when the supply voltage is less than a first voltage, and the first control signal is equal to a second voltage when the supply voltage is substantially equal to or greater than the first voltage. The second voltage is less than a lower switching point of the inverter, the first voltage being based at least in part on the first threshold voltage, the reset signal being a function of the second control signal.

摘要： Board level conditions associated with the operation of multiple LEDs are sensed and used to control a driver that powers the LEDs. The driver is controlled via a 0-10V control interface. The board-level conditions include, but are not limited to, temperature, ambient light, light intensity, operating time, time of day, current, and voltage. An on-board intelligent (OBI) controller processes the 0-10V control signal before it is provided to the driver to better control the LEDs. In some systems the OBI controller works in conjunction with a separate 0-10V controller that controls one or more luminaires.

摘要： The present invention provides a method and circuit for controlling the flow of current through a load. In a preferred embodiment, an oscillator generates a pulse signal of constant frequency. A pulse width modulator adjusts the duty cycle of the pulse signal in response to a dimming level signal input indicative of the desired level of current flow through the load. A converter receives the pulse signal as an input and converts it into an AC signal, the frequency of which follows the frequency of the pulse signal and the symmetry of which varies with the duty cycle of the pulse signal. The load is connected into a resonant circuit tuned such that a change in the symmetry of the AC signal changes the level of current flowing through the load.

摘要： A modular self-diagnostic assembly for controlling diagnostic, charge and transfer functions necessary to operation of fluorescent emergency lighting packs also referred to as inverters or fluorescent battery packs used particularly in emergency lighting systems such as are configured for operation with fluorescent lighting fixtures and the like. Self-test/self-diagnostic circuitry contained within a module separate from an emergency lighting pack functions as an add-on accessory to existing emergency lighting packs without need for modification of structure or circuitry of the lighting pack. The self-diagnostic module of the invention connects electrically and mechanically to the lighting pack through appropriate leads terminated by an appropriate header and further connects mechanically and electrically to a test switch module through appropriate leads terminated by an appropriate header. The resulting physical assembly is modular in concept with a first housing containing the conventional emergency lighting pack, or inverter, a second housing separate from the first housing and containing circuitry for controlling diagnostic, charging and transfer functions, the self-diagnostic module contained by the second housing connecting to the test switch module. Particular circuitry which can be incorporated into the self-diagnostic module provides control and self-test functions although other circuitry capable of appropriate function can be contained within the self-diagnostic module.
