  • Patent number: 10869734
    Abstract: A lighting system for an operating room wherein machine-controlled light sources are Bluetooth™-enabled to allow them to locate and track the movement of a device worn on the hand or wrist of a surgeon or other operating room personnel. In preferred embodiments, the system described herein will accommodate light source tracking for multiple surgeon-worn devices worn by one or more wearers. The system is capable of toggling between modes of following the wearer's movement and focusing on a single point determined by the wearer, where mode swapping can be controlled by the surgeon from the device itself. The system preferably accommodates the adjustment of multiple characteristics of the light source, such as light intensity, from the hand or wrist device. A periphery ribbon may also be used to control the direction of light sources. Applications of the invention y stretch to other fields such as construction or theater lighting.

  • Patent number: 10757787
    Abstract: An LED security light with an integrated motion sensor includes a PIR motion sensing unit and an LED load integrated together to become a compact lighting device. The PIR motion sensing unit is a two-portion design with a Fresnel lens either integrating with a light diffuser or as a separate piece positioned right behind the light diffuser and with a PIR motion sensor positioned at a focal point of the Fresnel lens and encircled by LEDs, wherein the Fresnel lens collects infrared ray signals generated by a moving body and remotely converges infrared ray signals on the PIR motion sensor. A signal processing circuitry decides whether the infrared ray signals represent an intrusion in order to turn on the compact lighting device. When the compact lighting device of this art is turned on, there is no shadow effect which reduces the lumens output of the security light.

  • Patent number: 10637282
    Abstract: A light fixture includes a driver for driving a light engine based on control signals received from a controller coupled to the driver. The driver is further connected to an AC power source and is configured for detecting a power loss from the AC power source and generating a power loss signal. Upon detecting the power loss, the driver sends the power loss signal to the controller. Based on the power loss signal, the controller sends an emergency egress mode control signal to the driver which drives the light engine in the emergency egress mode, i.e. at its full intensity for an emergency time period. Upon expiration of the emergency time period or upon the recovery of the AC power, the controller exits the emergency egress mode by sending a normal control signal to the driver.

  • Patent number: 8988014
    Abstract: A wake-up system includes an illumination apparatus and an interface apparatus. A wake-up time is input to the interface apparatus. The illumination apparatus varies output and color temperature of wake-up light that it irradiates. The output of the irradiated wake-up light is increased from a wake-up operation start time to the wake-up time. Color temperature of the wake-up light is controlled to become higher in one period than in another period between the wake-up operation start time to the wake-up time.

  • Patent number: 8963432
    Abstract: According to one embodiment, a lighting system includes a luminaire and a lighting control device. The lighting control device includes an operation section, a target-value managing section, a transmitting section, and a display section and controls the luminaire. The target-value managing section stores an operation state of the luminaire and, when the operation section is operated, calculates an operation target value on the basis of the stored operation state of the luminaire and updates the operation state to the operation target value serving as an operation state of the luminaire after the operation. The transmitting section transmits the operation target value as a radio signal. The display section performs display based on the operation target value.

  • Patent number: 8960954
    Abstract: Control system for sea turtle lights uses regulated lights, based upon satellite generated day signals and non-regulated lights. A user programmable timer permits the user to set time of day lighting operations. A seasonally fixed timer, fixed with a governmentally approved sea turtle season permits activation of the regulated lights. Outside of turtle season, non-regulated lights are used. The user turns ON and OFF the lights daily. An integrated lighting control system includes a central control unit having the user programmable timer and the seasonally fixed timer and the receiver with a processor and memory which generates lighting commands. A controllable light selector switch receives the lighting commands via a wired or wireless network. The method controls lights affecting sea turtles, which lights are subject to governmental regulation and seasonal operation. All light controls are further based upon the user set time of day and day of week lighting times.

  • Publication number: 20150002023
    Abstract: A light-emitting diode (LED) device includes first and second LED dies with the same structure and that are both encapsulated by the same silicone layer. The first LED is supplied with sufficient drive current to illuminate the LED. Control circuitry supplies the second LED with a constant current, determines the voltage across the second LED, and calculates the temperature of the second LED based on the voltage across the second LED. The constant current has a maximum magnitude that never exceeds the maximum magnitude of the drive current. The LED device is able to calculate the temperature of a diode with a gallium-nitride layer (GaN or GaInN) that is receiving a large drive current and emitting blue light by determining the voltage across an adjacent similar diode with a gallium-nitride layer through which a small constant current is flowing. Preferably, the band gap of the LEDs exceeds two electron volts.
