摘要： A two-wire load control device (such as, a dimmer switch) is operable to control the amount of power delivered from an AC power source to an electrical load (such as, a high-efficiency lighting load) and has substantially no minimum load requirement. The dimmer switch includes a bidirectional semiconductor switch, which is operable to be rendered conductive each half-cycle and to remain conductive independent of the magnitude of a load current conducted through semiconductor switch. The dimmer switch comprises a control circuit that conducts a control current through the load in order to generate a gate drive signal for rendering the bidirectional semiconductor switch conductive and non-conductive each half-cycle. The control circuit may provide a constant gate drive to the bidirectional semiconductor switch after the bidirectional semiconductor switch is rendered conductive each half-cycle. The bidirectional semiconductor switch may comprise, for example, a triac or two field-effect transistors coupled in anti-series connection.

摘要： A dimmer switch for controlling the amount of power delivered to and thus the intensity of a lighting load comprises a visual display operable to provide a visual indication representative of energy savings and usage information. The visual display may comprise a single visual indicator or a linear array of visual indicators. The visual display is illuminated in a first manner when the intensity of the lighting load is less than or equal to a predetermined eco-level intensity, and is illuminated in a second manner when the intensity of the lighting load is greater than the eco-level intensity. For example, the single visual indicator may be illuminated a first color, such as green, when the intensity of the lighting load is less than or equal to the eco-level intensity, and illuminated a second different color, such as red, when the intensity of the lighting load is greater than the eco-level intensity.

摘要： A two-wire load control device, such as, a dimmer switch, for controlling the amount of power delivered from an AC power source to an electrical load comprise a bidirectional semiconductor switch having first and second anti-series connected switching transistors (such as, for example, field-effect transistors) that are adapted to be coupled between the source and the load, and are controlled to be conductive and non-conductive in a complementary basis. The bidirectional semiconductor switch is operable to be rendered conductive and to remain conductive independent of the magnitude of a load current conducted through semiconductor switch. The dimmer switch also comprises a drive circuit for rendering the first and second switching transistors conductive and non-conductive each half-cycle on the complementary basis, so as to control the amount of power delivered to the electrical load to a desired amount of power.

摘要： A two-wire smart load control device, such as an electronic switch, for controlling the power delivered from a power source to an electrical load comprises a relay for conducting a load current through the load and an in-line power supply coupled in series with the relay for generating a supply voltage across a capacitor when the relay is conductive. The power supply controls when the capacitor charges asynchronously with respect to the frequency of the source. The capacitor conducts the load current for at least a portion of a line cycle of the source when the relay is conductive. The load control device also comprises a bidirectional semiconductor switch, which is controlled to minimize the inrush current conducted through the relay. The bidirectional semiconductor switch is rendered conductive in response to an over-current condition in the capacitor of the power supply, and the relay is rendered non-conductive in response to an over-temperature condition in the power supply.

摘要： A two-wire load control device, such as a dimmer, is operable to control the amount of power delivered to an electrical load, such as a magnetic low-voltage (MLV) load, and comprises a bidirectional semiconductor switch, a timing circuit, a trigger circuit having a variable voltage threshold, and a clamp circuit. When a timing voltage signal of the timing circuit exceeds an initial magnitude of the variable voltage threshold, the trigger circuit is operable to render the semiconductor switch conductive, reduce the timing voltage signal to a predetermined magnitude less than the initial magnitude, and to increase the variable voltage threshold to a second magnitude greater than the first magnitude. The clamp circuit limits the magnitude of the timing voltage signal to a clamp magnitude between the initial magnitude and the second magnitude, thereby preventing the timing voltage signal from exceeding the second magnitude. Accordingly, multiple attempted firings of the semiconductor switch are avoided, and the MLV dimmer is prevented from conducting asymmetric current when an MLV transformer of the MLV load is unloaded.

摘要： A two-wire switching circuit can handle a large inrush current, but does not require a neutral connection or a heavy-duty mechanical switch or relay. The switching circuit comprises a mechanical air-gap switch and a controllably conductive device, which are coupled in series and are adapted to be coupled between an AC power source and an electrical load when the mechanical switch is in a first position. A first delay circuit is coupled in parallel with the controllably conductive device and in series with the mechanical air-gap switch. A latching circuit, which is responsive to the first delay circuit, is coupled to the controllably conductive device for controlling the controllably conductive device. The first delay circuit causes the latching circuit to control the controllably conductive device to be conductive after a first predetermined time after the mechanical air-gap switch changes to the first position.
