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 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, a controller for rendering the relay conductive and non-conductive, 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 controller is operable to determine when the magnitude of the supply voltage reaches a maximum supply voltage threshold, and render the relay non-conductive immediately after the supply voltage reaches the maximum supply voltage threshold.

摘要： A light adjusting apparatus comprising a lamp connected to a commercial a.c. power supply via a triac, and a switching control circuit operable by a direct current obtained by directly rectifying the current of the power supply for controlling the conduction timing of the triac based on the zero-cross timing of the power supply. The conduction timing of the triac is controlled by a signal obtained by producing a pulse-width modulated light adjusting signal from a signal generating circuit by a light-emitting element, causing a photodetector in the control circuit to receive the adjusting signal and subjecting the resulting output of the control circuit to pulse-width demodulation.

摘要： An apparatus and method for enabling an automatic calibration sequence for a light control system having a daylight harvesting scheme is disclosed herein. An ambient light sensor connects to a detection circuit for detecting the amount of ambient light within a given zone. A microprocessor connects between the detection circuit and a dimming circuit for providing control to initiate dimming and to start the auto-calibration sequence. Responsive to the amount of ambient light detected, the dimming circuit controls the power supplied to a plurality of electrical loads. A storage unit connects to the microprocessor for storing minimum light levels assessed during the auto-calibration sequence wherein the ambient light levels are monitored for a predetermined amount of time to determine the lowest level of ambient light generated for the purpose of setting and storing a target voltage level associated with such.

摘要： A ceiling fan assembly includes a fan and a light-sensitive circuit for controlling an illumination level of a light as a function of an ambient illumination level surrounding the ceiling fan assembly by selectively controlling or fixing a conduction phase angle of an AC power signal provided to the light. The light-sensitive circuit includes a photocell, a phase control circuit and a cutoff Circuit which prevents flicker at low illumination levels. The photocell is responsive to the ambient illumination level and has a conduction state. The conduction state changes in response to the ambient illumination level. The phase control circuit selectively varies or fixes a conduction phase angle associated with the AC power signal, which correspondingly determines a variation in the illumination level of the light. In response to the photocell, the phase control circuit selectively varies or fixes the conduction phase angle, and thus the illumination level associated with the light when the photocell exhibits an open circuit, and conversely, prevents the AC power signal from being provided to the light when the photocell exhibits a short circuit.

摘要： A lamp control apparatus that responds to sudden increases in ambient light by energizing a light bulb for a short period of time. A first voltage comparator is connected to a photocell circuit such that its output normally presents a high impedance to a timing capacitor connected to the input of a second voltage comparator which, in turn, provides a gate signal for a triac power switch. The first comparator will switch to a low impedance output if a sufficient amount of light suddenly appears at the photocell. This low impedance will rapidly discharge the timing capacitor and allow the second comparator to energize the lamp. The timing capacitor will then slowly charge back to a voltage that will cause the second comparator to remove the gate signal for the triac, thereby de-energizing the lamp.
