摘要： The present invention is directed to an improved combination LED light troffer and passive UVGI air chamber for providing both general lighting and disinfection of contaminated used air that is cleaned, treated, and purified before returning back to the HVAC system for recycling. The improvement including an internal and quiet UVGI air chamber that uses natural air convection from the HVAC system to take in air for sanitizing inside the UVGI air chamber for a brief amount of time, and then releasing it out to the air return of the HVAC system. The UVGI air chamber being operational only when the HVAC system is active and independent of the operation of the LED light troffer for general lighting. UVC light sources include germicidal fluorescent lamps, cold cathode lamps, excimer type lamps, and UVC type LED emitters in different UVC wavelengths.

摘要： A flexible lighting device includes an elongated flexible tube with a translucent tube shell and opposed tube ends and a flexible circuit board set in the tube so that it extends between the tube ends. The flexible circuit board has opposed interior and exterior surfaces. Electrical circuitry is mounted to the circuit board and connected to an external input source and an output source of electrical power. The circuit board defines a number of cut-outs, preferably those of a generally diamond shape. The device is described in two embodiments: one with inwardly directed LEDs on the circuit board directed into the tube and one with outwardly directed LEDs on the circuit board directed out of the tube. The method of making the flexible lighting device is also described.

摘要： A satellite TV security system including a TV satellite operated by a satellite TV provider directed to a television set of a satellite TV subscriber that defends the satellite TV provider from illegal reception of TV signals from a TV satellite. An addressable integrated receiver/decoder (IRD) positioned in the TV set top box has an assigned identification number and a smart card positioned in the IRD has an assigned identification number. A security module is provided that is integrated with the IRD. Upon command of the satellite TV provider or automatically, the security module makes a periodic verification of a match of the two identification numbers. Lack of verification of a match triggers a signal from the security module to the IRD to stop transmitting TV signals to the subscriber television. As an alternative verification, the security module initiates periodic verifications of the operability of the telephone line connection between the satellite TV provider and the IRD of the subscriber. Lack of verification of the operability of the telephone line triggers a signal from the security module to the IRD to stop transmitting TV signals to the subscriber TV. The two systems of verification can be operated independently or simultaneously. The subscriber telephone number can be added as an assigned identification number, so that a three-way verification of identification numbers by the security module is required for continued transmission of TV signals to the subscriber television.

摘要： A diode light source for theatrical and architectural lighting has a number of separate, flat, rigid panels for mounting light-emitting diodes. These emit diode light beams to a common focal area. A group of the diodes is mounted on each panel, and each panel has an inner and outer panel. A screw arrangement selectively positions the panels, with each oriented at a selected angle relative to an axis, and with each diodes group emitting diode light beams transverse to each separate panel. Each inner panel is flexibly secured to the screw arrangement. The panels hold the diodes and act as electrical circuit boards for transmitting direct electrical current to the diodes on the panels. The screw includes an elongated, externally threaded cylinder with opposed inner and outer ends that is rotatably aligned with the axis and mounted on a corresponding internally cylindrical threaded nut.

摘要： A LED luminaire track lighting system includes an elongate track, having a number of longitudinal guideways, for attachment to a support surface, as well as a number of current conductors arranged within at least some of the guideways. The first of these conductors are power conductors and the second conductors are data conductors, the conductors being electrically isolated from each other. The lighting system further contains a first adapter for connection to a source of electrical power for the power conductors, and a second adapter for connection to a source of control data for application of data to the data conductors. There is at least one LED color-changing luminaire present in the system, and this luminaire contains a number of LEDs, each of which, when energized, generates a single color out of a discrete plurality of colors. A data converter converts data along the data lines to control the currents in the individual groups of color LEDs so that they create a desired composite color. Further, at least electrically, the LED color-changing luminaire is at least electrically connected to the power conductors and data conductors in the track.
