| 20100134020 | LED LIGHTING CONTROL INTEGRATED CIRCUIT HAVING EMBEDDED PROGRAMMABLE NONVOLATILE MEMORY - For providing a compact high-precision lighting control means to drive an LED lighting module, a lighting control integrated circuit is set forth to perform an accurate lighting control. At least one nonvolatile memory is embedded in the lighting control integrated circuit for storing a plurality of lookup tables. One lookup table provides related data for setting the driving currents of the LED lighting module based on spacing or pitch of LED disposition of the LED lighting module. Another lookup table provides related data to recover uniformity for different LED damage situations of the LED lighting module. The other lookup tables are applied to perform compensation processes on the driving currents concerning temperature variation, ambient light intensity, aging degradation, and power-on time. In addition, a signal processing unit, a pulse-width-modulation signal generating module, and a driving module are incorporated in the lighting control integrated circuit for signal processing and current driving. | 06-03-2010 |
| 20110050106 | Online Time Dimmer - An online time dimmer is disclosed, which comprises a base, an electric circuit unit lodged in the base and a top cover joined with the base correspondingly. The electric circuit unit is functionally made up of a dimmer circuit and a time circuit, and structurally comprises a power switch and a time switch, which are activated by a switch button and a time button respectively. When in use, one end of the unit connects electrically to a power supply through electric wires and a plug, while the other end to a lighting load through electric wires. Once depressing the switch button will in turn press the power switch, which activates power-on, power-off and the adjustment of brightness operated on the lighting load through the dimmer circuit. And depressing the time button will in turn press the time switch, which enables the time circuit to operate time setting on the lighting load. | 03-03-2011 |
| 20110095691 | Lighting Apparatus And Lighting Fixture - A lighting apparatus includes a lighting circuit unit, a timer unit, a life judgment unit, a timing adjustment unit, and an indication unit. The lighting circuit unit is configured to activate a light source. The timer unit is configured to measure accumulated operation time of the lighting circuit unit. The life judgment unit is configured to store a first judgment time and a second judgment time longer than the first judgment time. The life judgment unit is configured to compare the accumulated operation time with the first judgment time and output a first judgment signal when the accumulated operation time becomes equal to the first judgment time. The life judgment unit is configured to compare the accumulated operation time with the second judgment time and output a second judgment signal when the accumulated operation time becomes equal to the second judgment time. The timing adjustment unit is configured to vary timing at which the life judgment unit outputs the first judgment signal. The timing adjustment unit is configured to vary timing at which the life judgment unit outputs the second judgment signal. The indication unit is configured to indicate, upon receiving the first judgment signal from the life judgment unit, a first level of the end of life with the light source kept turned on. The indication unit is configured to indicate, upon receiving the second judgment signal from the life judgment unit, a second level of the end of life. The second level of the end of life is later than the first level of the end of life. | 04-28-2011 |
| 20140021864 | FUNCTIONAL CONTROL ADAPTER FOR LIGHT GENERATING DEVICE - A functional control adapter for light generating devices includes a female portion, a male portion, and a control module. The female portion has an inlet body. The inlet body has a housing member having a first contact module. The male portion has an outlet body connected to the inlet body. A second contact module is disposed on the exterior of the outlet body. The control module is located at the inlet body and connected electrically to the first contact module of the female portion and the second contact module of the male portion. The adapter and the light source are joined separately, thus the lighting device can be dismounted or installed with convenience, and individual parts can be replaced as needed for reducing repair cost. | 01-23-2014 |
| 20140246981 | ACTUATOR ASSEMBLY FOR A WALLBOX DIMMER - A wall-mounted dimmer may include an actuator assembly configured to translate a touch interaction with the dimmer into a desired dimming level. The actuator assembly may include a control interface having a resilient, deflectable membrane, a plurality of force-sensitive impedance members supported by the membrane, and an actuator configured to transfer a touch along the actuator to the membrane, causing the membrane to actuate one or more corresponding force-sensitive impedance members. The force-sensitive impedance members may be configured to make contact with corresponding ones of a plurality of open circuit pads supported by a printed circuit board. Each of the plurality of open circuit pads may correspond to a predetermined dimming level applied to a lighting load electrically connected to the dimmer. The control interface may be configured such that contact between the force-sensitive impedance members and corresponding ones of the open circuit pads is pressure sensitive. | 09-04-2014 |
| 20160066394 | NETWORKED, WIRELESS LIGHTING CONTROL SYSTEM WITH DISTRIBUTED INTELLIGENCE - A programmable lighting control system integrates time-based, sensor-based, and manual control of lighting and other loads. The system includes one or more groups of controlled lighting areas, which may be, e.g., floors of a building. Each group may have one or more lighting zones, which may be, e.g., individual rooms or offices on a building floor. Each lighting zone includes occupancy and/or daylight sensors that may be wirelessly coupled to a gateway of the group. Each gateway is coupled to a network, such as, e.g., a local area network (LAN). Control software, residing on a computer (e.g., a personal computer or a server) coupled to the network and accessible via the network, remotely communicates with and controls the lighting zones either individually, groupwise, or globally. Each lighting zone can also be locally controlled at the gateway and can function independently of the control software and the gateway. | 03-03-2016 |
