Waveform detection, in particular for the representation of the root mean square of a waveform

The instantaneous value of an intermediate waveform I is the instantaneous value of a unipolar waveform U multiplied through amplification by an upscaling factor UF of 1.5. A plateau value P is subtracted from the intermediate value I, and the result of this subtraction is multiplied by a multiplication factor MF of 0.6. The result of the multiplication is added to the plateau value P, which sum becomes an auxiliary waveform A. During the 'fall-below' periods F, the value of a combined waveform C is arranged to follow whichever is the highest of the auxiliary value A and the plateau value P. Outside the fall-below periods, the value of the combined waveform C follows whichever is the highest of the unipolar value U and the plateau value P. This combined waveform C has, for a given plateau level P, a narrower fall-below window. Phase-chopping thus has an effect on the power of the output signal over a greater range of the cycle than can be provided by the corresponding prior art arrangement ...

A two-wire dimmer is operable to control the amount of power delivered to a magnetic low-voltage (MLV) load and comprises a bidirectional semiconductor, 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, the MLV dimmer is prevented from conducting asymmetric current when an MLV transformer of the MLV load is unloaded.

Power reducing circuit for A.C. Load

The purpose of the invention is the provision of a load modification arrangement in an electrical circuit with the objects of saving energy and of prolonging the working life of the load device 10 for example a lamp or a motor. A triac 14, which is triggered by a diac 16 and a fixed phase shift circuit 18, causes the load to operate at a fixed proportion of its nominal rated power, eg. 60 to 90% and particularly 75%.

The trigger circuit may also be modified to incorporate a holding current arrangement adequate to overcome any tendency of the triac to turn off prematurely. ...

A power controller converts a line voltage to an RMS load voltage for a lamp, and includes a switch and a microcontroller that operates the switch to define the RMS load voltage. The microcontroller senses a load voltage of the lamp, compares the sensed load voltage to a reference RMS voltage, and operates the switch in response to the comparison so that the RMS load voltage is substantially constant at the reference RMS voltage over an operating range of the line voltage and so that the RMS load voltage decreases with decreasing line voltage at line voltages less than the operating range. The operating range of the line voltage is defined to have a minimum that is a non-zero line voltage at which a load current is a predetermined maximum. The voltage conversion circuit may be a phase clipping circuit or a pulse width modulation circuit.

Power control circuit with phase-controlled signal input

Electronic control systems and methods

An apparatus in an electronic control system allows two or three wire operations. A power supply (150) can supply power to the enclosed circuity in both two and three wire installations. Two separate zero cross detectors are used such that timing information can be collected in both two or three wire installations. Both zero cross detectors (110) are monitored and are used to automatically configure the electronic control. Over voltage circuity senses an over voltage condition across a MOSFET which is in the off state and turns the MOSFET on so that it desirably will not reach the avalanche region. Over current circuity senses when the current through the MOSFET's has exceeded a predetermined current threshold and then turns the MOSFETs off so they do not exceed the MOSFETs' safe operating area (SOA) curve. Latching circuity (120) is employed to keep the protection circuity in effect even after a fault condition has cleared. Lockout circuity (130) is used to prevent one protection circuit from tripping after the other circuit has already tripped from a fault condition. The protection circuity output is desirably configured such that it can bypass and override the normal turn on and turn off impedance and act virtually directly on the gates of the MOSFETs. Preferably, the system has a high effiiciency switching type power supply in parallel with a low frequency controllably conductive device.

Dimmer for preventing asymmetric current flow through an unloaded magnetic low-voltage transformer

A two-wire dimmer is operable to control the amount of power delivered to a magnetic low-voltage (MLV) load and comprises a bidirectional semiconductor, 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, the MLV dimmer is prevented from conducting asymmetric current when an MLV transformer of the MLV load is unloaded.

Semiconductor AC switch units

A switch unit 1 of an AC power-supply circuit for a lamp 2 includes a triac 7 connected in series with the lamp 2 to regulate current supply to it in dependence upon voltage across a resistor 13. The resistor 13 is connected in series with the AC input 11,12 to a bridge rectifier 10 in a current path that shunts the triac 7. A thyristor 14 is connected across the DC output 16,17 of the rectifier 10 in series with a resistor 15 so that the triac 7 is switched ON or OFF from the shunt-path resistor 13 in dependence upon whether the thyristor 14 is OFF or ON respectively. Gate control of the thyristor 14 is effected from the collector of a transistor 23 which is turned ON or OFF by a control-function signal applied to its base from a controller 9. DC power for the transistor 23 and the controller 9 is supplied from the rectifier 10 across a capacitor 21 that is shunted by a zener diode 22 and charged via a diode 26 and resistor 27 by current drawn from the path through the thyristor 14. The circuit may power an electric motor, for example, of a heating system, instead of the lamp 2.

Differential illumination sensitive switching circuit

A first phototransistor (20, 20') is mounted on the structure such as a home (12) or a garage (14) to sense the level of ambient illumination. A second phototransistor (22, 22') senses both the level of ambient illumination and illumination from the headlights of an approaching vehicle or the like. The phototransistors are arranged with a pair of resistors (54, 56) in a balanced bridge (50). A central bridge junction (52) assumes a higher potential when both phototransistors are illuminated the same, whether light or dark, and a lower potential when the second phototransistor is illuminated more brightly than the first. In response to the uneven illumination of the phototransistors, a timer (60) produces an output signal for a preselected duration. An optic coupler (90) gates a triac (92) conductive for the preselected duration of the timer. The triac is connected in series with exterior security lights (24, 24') for illuminating the area adjacent a driveway, home, and garage to provide a lighted path for the vehicle occupant after disembarkation of the vehicle.

Circuit arrangement for radio interference suppression in control units based on the phase control principle

Zur Funkentstörung von Spannungsregelschaltungen, die nach dem Phasenanschnittsprinzip arbeiten, wird eine Entstördrossel in Reihe zu dem als Regelglied arbeitenden Halbleiterschalter (T) gelegt. Die aus dem Halbleiterschalter (T) und der Entstördrossel (Dr1) bestehende Reihenschaltung liegt im Ladestromkreis und wird von einem ebenfalls zur Entstörung dienenden Kondensator (C) überbrückt. Dieser Kondensator (C) hat nachteilige Auswirkungen, wenn die den Zündzeitpunkt des Halbleiterschalters beeinflussende Steuerschaltung ferngesteuert werden soll. Hierzu wird, ausgehend von einem Sender der Netzspannung, eine relativ hochfrequente Steuerspannung überlagert, für die der Kondensator einen niedrigen Widerstand und damit eine hohe Last bedeutet. Durch das Einfügen einer weiteren Drossel in den Lastkreis wird der Widerstand für höhere Frequenzen größer und damit die Belastung des Senders herabgesetzt. Die Verwendung eines Ferritkernes für die zusätzliche Drossel ermöglicht eine relativ große Induktivität bei kleinen Abmessungen. For radio interference suppression of voltage control circuits that work according to the phase control principle, an interference suppression choke is placed in series with the semiconductor switch (T), which works as a control element. The series circuit consisting of the semiconductor switch (T) and the interference suppression choke (Dr1) is located in the charging circuit and is bridged by a capacitor (C), which is also used for interference suppression. This capacitor (C) has disadvantageous effects if the control circuit influencing the ignition timing of the semiconductor switch is to be remotely controlled. For this purpose, starting from a transmitter of the mains voltage, a relatively high-frequency control voltage is superimposed, for which the capacitor means a low resistance and thus a high load. By adding another choke to the load circuit, the resistance for higher frequencies increases and the load on the transmitter is reduced. ...

Method of programming a lighting preset from a radio-frequency remote control

The present invention provides a method of programming a preset intensity of a dimmer switch from a radio-frequency (RF) remote control. A user is able to adjust the intensity of the lighting load to a new intensity and subsequently press and hold a preset button on the remote control to program the new intensity as the preset intensity. The remote control transmits a wireless transmission to the dimmer switch, which immediately responds to the actuation of the preset button by controlling the intensity of the lighting load to an initial preset intensity. The dimmer switch then blinks a light-emitting diode representative of the new intensity to provide feedback that the dimmer switch is in the process of programming the preset intensity to the new intensity. Eventually, the dimmer switch stores the new intensity as the preset intensity and stops blinking the light-emitting diode.

Programmable gradual lighting diminishing system

A domestic lighting system for progressively dimming an electrically powered lamp. The system being programmable to cause the power supplied to the lamp to vary between a high setting and a low setting over a chosen time period, the lower setting can completely extinguish the light or maintain it at a relatively low level of illumination so as to function as a nightlight. The system is equipped with various controls to set the maximum and minimum outputs of the dimmer function and has a time control 18 for regulating the period over which electrical power is passed from the unit 14 to the lamp 11 and over which the illumination is decreased from a high level set by control 16 to the mm level set by control 17. System control can also be via a remote control 19 using electromagnetic (infrared) or acoustic (ultrasound) signals 21.

Smart load control device having a rotary actuator

A load control device for controlling the amount of power delivered from an AC power source to an electrical load comprises a rotary actuator, such as a rotary knob or a rotary wheel. The load control device increases and decreases the amount of power delivered to the electrical load in response to rotations of the rotary knob in first and second directions, respectively. The load control device accelerates the rate of change of the amount of power delivered to the load in response to the angular velocity of the rotary actuator. The load control device generates a ratcheting sound when the rotary actuator is rotated in the first direction at a high-end intensity of the load control device. The load control device is operable to control the electrical load in response to both actuations of the rotary actuator and digital messages received via a communication link.

A device permitting of economizing electric lighting energy

The device is to be mounted on any individual chandelier or any form of lamp: normal bulb (10), fluorescent, neon, sodium mercury vapour etc. When the space is not illuminated very much, the lamp (10) in consequence of the electronic circuit contained in the device according to the invention (1) lights up with an intensity so as to compensate for the reduction of the illumination of the surroundings. The device therefore controls every individual lamp economizing energy because unlike the known devices controlling groups of lamps it acts so as to subdue the light emitted by the lamp or bulb gradually the more the space surrounding it is illuminated. The luminous energy emitted is inversely proportional to the luminous intensity of the surrounding space. The luminous energy of the space is preferably communicated to the device (1) by means of a bundle of optical fibres (2) avoiding the light reflected by the shield (14) of the lamp.

Master electrical load control system

A system controls power to multiple a.c. lighting loads from both a central location and from individual controls that are located near the loads. The system includes individual wallbox dimmers that include enabling switches, a master control, and isolation means to accept input signals from the master control and to provide output signals to the dimmers. In a preferred embodiment, a dimmer also provides to the master control a signal that indicates the power being provided to the load that the dimmer controls. Preferably the individual controls provide linear slide dimming, in which the power provided to a load is determined by the slider position. The system permits simplified installation and replacement of system components.

System for individual and remote control of spaced lighting fixtures

A plurality of spaced ceiling mounted fixtures or other controllable electrical appliances have radiation detectors mounted within each fixture and wired internally of the fixture to a dimming circuit or to a ballast. The radiation detectors have sensitivity over a wide angle and have elongated plastic radiation conduction rods which extend to or beyond the plane of the lens of the fixture to be located free of shadow effects of reflections of the fixture lens. A flexible end light fiber optics can be used in place of the acrylic rods. A narrow beam radiation transmitter selectively illuminates one of the rods or end light fiber optics without illuminating the others. The dimming circuits or ballasts within the fixtures can be further controlled by external dimmers, occupancy sensors, timeclocks, photosensors and other types of input devices. The radiation detector and ballast can occupy a common housing and share the same power supply and circuit board. The microcontroller for the radiation detector operates with a 4 of 4 voting mode until a valid signal is detected to switch the system to a 3 of 4 voting mode. A novel mounting adaptor for mounting a visible light fiber optic cable is disclosed with the visible light fiber optic cable conducting infrared radiation for up to 24 inches.

Variable color lighting system

The variable color lighting system includes a plurality of lamps controlled by a central controller. The central controller has a number of control channels, and each lamp is preset to be responsive to a specific control channel. To accomplish this, a lamp includes an address circuit which can be varied to respond to a unique address signal from any of the control channels. When the proper address is received, intensity control circuitry within the lamp responds to a digital intensity control signal transmitted by the central controller. The central controller causes all light sources in a lamp to fade from one end intensity value to the next and to reach the next intensity value simultaneously.
