Patent number: 10492275Abstract: A system and method provide fail-safe operation of a lighting system. A lighting level detector is used to obtain a baseline lighting level for a low-intensity light. If the detector measures less than the baseline level when an occupancy sensor determines the space is unoccupied, a high-intensity light is energized and an indication is provided to a user that the low-intensity light has failed. A method provides daylighting operation of a lighting system. An occupancy sensor can have Wi-Fi functionality to enable remote configuration of the sensor. A line voltage occupancy sensor can include an interface with low voltage devices. An occupancy sensor can include an integral interface to enable an external control system to override the sensor's normal logic under emergency conditions. An occupancy sensor can include an active temperature compensation feature. An occupancy sensor can also incorporate an automatically adjustable coverage area.Type: GrantFiled: April 4, 2019Date of Patent: November 26, 2019Assignee: Leviton Manufacturing Co., Inc.Inventors: Richard A. Leinen, Brian Carberry, David Buerer, Jaiganesh Balasubramanian

Publication number: 20130082608Abstract: A dimming ballast allowing individual control of multiple lamps is described. The ballast includes a lamp driver to control at least one lamp. Further, the ballast includes a current sensing module , connected as part of a feedback loop from the at least one lamp to the lamp driver, the current sensing module being configured with a maximum allowable output current value for each lamp. A lamp resonant circuit, connected between the lamp driver and the at least one lamp, operates over the entire range of the output current values. A lamp status module is coupled to the lamp driver for monitoring at least one condition related to the at least one lamp being controlled. Moreover, a control module controls the lamp driver independently based on a feedback loop from the lamp status module. Various embodiments of the dimming ballast along with related methods are also described.Type: ApplicationFiled: September 29, 2011Publication date: April 4, 2013Applicant: Leviton Manufacturing Co., Inc.Inventor: Jaiganesh Balasubramanian
