  • Patent number: 8508169
    Abstract: A load control system provides for automatically controlling a position of a motorized window treatment to control the amount of sunlight entering a space of a building through a window located in a façade of the building in order to control a sunlight penetration distance within the space and minimize occupant distractions. The load control system automatically generates a timeclock schedule having a number of timeclock events for controlling the position of the motorized window treatment during the present day. A user is able to select a desired maximum sunlight penetration distance for the space and a minimum time period that may occur between any two consecutive timeclock events. In addition, a maximum number of movements that may occur during the timeclock schedule may also be entered. The load control system uses these inputs to determine event times and corresponding positions of the motorized window treatment for each timeclock event.

  • Publication number: 20130181630
    Abstract: A load control system comprises a load control device for controlling an electrical load receiving power from an AC power source, and a controller adapted to be coupled in series between the source and the load control device. The load control system may be installed without requiring any additional wires to be run, and is easily configured without the need for a computer or an advanced commissioning procedure. The load control device receives both power and communication over two wires, and the controller generates a phase-control voltage that has at least one timing edge in each half-cycle, and transmits digital messages by modulating a timing edge of the phase-control voltage relative to a reference edge. The controller may be operable to receive inputs from a plurality of different input devices, and the load control device may be operable to control a plurality of different loads.

  • Patent number: 8417388
    Abstract: A load control system for a building having a heating and cooling system and a window located in a space of the building is operable to control a motorized window treatment in response to a demand response command in order to attempt to reduce the power consumption of the heating and cooling system. When the window may be receiving direct sunlight, the motorized window treatment closes a fabric covering the window when the heating and cooling system is cooling the building, and opens the fabric when the heating and cooling system is heating the building. In addition, when the space is unoccupied and the heating and cooling system is heating the building, the motorized window treatment may open the fabric if the window may be receiving direct sunlight, and may close the fabric if the window may not be receiving direct sunlight.

  • Patent number: 8354803
    Abstract: A hybrid light source comprises a discrete-spectrum lamp (for example, a fluorescent lamp) and a continuous-spectrum lamp (for example, a halogen lamp). A control circuit individually controls the amount of power delivered to the discrete-spectrum lamp and the continuous-spectrum lamp in response to a phase-controlled voltage generated by a connected dimmer switch, such that a total light output of the hybrid light source ranges throughout a dimming range. The continuous-spectrum lamp is driven by a continuous-spectrum lamp drive circuit, which is operable to conduct a charging current of a power supply of the dimmer switch and to provide a path for enough current to flow through the hybrid light source, such that the magnitude of the current exceeds rated latching and holding currents of a thyristor of the dimmer.

A control circuit individually controls the amount of power delivered to the discrete-spectrum lamp and the continuous-spectrum lamp in response to a phase-controlled voltage generated by a connected dimmer switch, such that a total light output of the hybrid light source ranges throughout a dimming range. The discrete-spectrum lamp is turned off and the continuous-spectrum lamp produces all of the total light intensity of the hybrid light source when the total light intensity is below a transition intensity.

  • Publication number: 20120306376
    Abstract: 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 dimmer switch comprises an intensity adjustment actuator, such as a slider knob or a rotary knob, which may be coupled to a potentiometer for adjusting the amount of power delivered to the lighting load. The potentiometer may comprise a dual potentiometer including a resistive element and a conductive element having a cut. The visual display may comprise a single visual indicator, which 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.

  • Publication number: 20120286940
    Abstract: A battery-powered remote control for radiating wireless signals to control a controlled device has a night light that glows whereby it is visible in a darkened room and the battery lasts at least about three years. It also includes a wireless transmitter, a controller, a battery and a control element. The control element generates a signal when activated to cause the controller to operate the wireless transmitter to transmit a wireless signal to control the controlled device. The night light comprises a light emitting diode and a light pipe having a textured front surface. A power supply circuit for the LED provides an LED current from the battery. The LED has a normal operating current range and the LED current is several orders of magnitude below the normal operating current range.

  • Publication number: 20120261079
    Abstract: A motorized window treatment to automatically control the position of a covering material in front of a window to save energy. The motorized window treatment has an eco-mode whereby to at least one climate characteristic is measured by a sensor to save energy by decreasing the load on a heating and/or cooling system of the room in which the motorized window treatment is installed. The motorized window treatment opens the covering material on sunny winter days to allow energy from sunlight to be stored in the mass of the room, and closes the covering material at night to insulate the room and allow the energy from the sunlight stored in the mass of the room to heat the room and reduce the load on the heating and cooling system at night.
