20080290821 | Electric Circuit for Individually Controlling Light-Emitting Elements and Optoelectronic Device - The present invention relates to an electric circuit. The electric circuit comprises at least six light-emitting elements and at least three switching networks for individually controlling the light-emitting elements. Each switching network is connected with at least four light-emitting elements. The at least three switching networks are connected with each other by parallel connections of respective two of the at least six light-emitting elements. The respective two light-emitting elements have opposite current blocking directions. | 11-27-2008 |
20090128061 | Methods and systems for operating and controlling theatrical lighting - A system and method for increasing a number of lights operated and/or controlled by dimmer boxes of theatrical light systems. In one embodiment, a master box is coupled to a chain of slave boxes in series. The master box receives a control signal and generates a switching signal for controlling the master box and the slave boxes. The switching signal is transmitted from the master box to the slave boxes through the series connections. Each of the master box and the slave boxes include a light signal input and a plurality of light signal outputs, and select among the plurality of light signal outputs according to the switching signal. | 05-21-2009 |
20090230895 | METHOD AND DEVICE FOR MAKING LIGHTING MODULES PART OF A DISPLAY DEVICE, WHICH LIGHTING MODULES HAVE BEEN BROUGHT RANDOMLY TOGETHER - The present invention relates to a method and device for communicating data to devices which have been brought randomly together, e.g. user equipment provided to a plurality of persons grouped within a geographical area, e.g. an audience or spectators, for example as used in concerts or sports events, in particular for example such that the user equipment effectively forms part of a light emitting display device. | 09-17-2009 |
20100213880 | LED LIGHT WITH SPECIAL EFFECTS - The current invention teach LED light device has special effects which meet persistence of vision theory to have LED or LEDs or LED array has quickly changing than the human eye response time within 1/16 to 1/24 second to let people see the message display from the said light device with special message, time, drawing, light patterns, light color changing.
