Abstract: An intrinsically safe (IS) luminaire disposed in a hazardous environment provides visible light and serves as a primary, auxiliary, back-up, and/or charging source of IS DC power for external devices disposed in the hazardous environment, such as process control devices and equipment. The luminaire includes a power converter that converts received power into DC power, an IS barrier that converts the DC power into IS DC power native to or utilized by a recipient external device, and a power distribution port via which IS DC power is delivered to the external device. In some configurations, the luminaire monitors communicates statuses, alerts, and/or other information corresponding to delivering IS DC power to one or more external devices to a host and/or portable communication device. The luminaire may include multiple IS barriers of same and/or different IS ratings, and may dynamically control activation/deactivation of the IS barriers and/or usages thereof.

Abstract: The present disclosure envisages an arrangement (100) for dissipating heat of a power supply unit (105) in a housing (110). The arrangement (100) comprises at least one packing member (120). The packing member (120) is disposed between the power supply unit (105) and an operative inner wall of the housing (110) to increase conductive thermal contact between inner walls of the housing (110) and the power supply unit (105). The arrangement (100) facilitates maximum surface contact between a power supply unit and inner walls of a housing.

Abstract: A smart luminaire system in which a primary luminaire controls and/or communicates with a set of one or more secondary luminaires may be disposed in a hazardous environment, such as an industrial process plant, manufacturing facility, oil refinery, etc. The primary luminaire may send driving commands to the set of secondary luminaires via an analog portion of a hybrid wired communication interface, and the driving commands may cause a driver of a second luminaire to energize on-board illumination source(s) at various intensities. The primary luminaire may send and/or receive administrative messages to/from the secondary luminaires via a digital portion of its hybrid wired communication interface. The smart luminaire system may be a stand-alone system, or may communicate with a controller or back-end system via a wireless communication interface of the primary luminaire, e.g., to receive control instructions and/or to send consolidated administrative messages on behalf of the smart luminaire system.

Abstract: A luminaire network improves energy efficiency, reduces light pollution, improves the robustness of luminaire control, and reduces maintenance time and costs by implementing intelligent and selective lighting control. For example, the luminaire network may automatically control dimming, light activation, light deactivation, static or dynamic luminaire grouping, and luminaire group control by implementing a hybrid control scheme that accounts for (i) local or global fixed schedules (e.g., based on time of day, worker schedules, etc.), (ii) detected daylight, (iii) detected motion of workers, and (iv) feedback from luminaires in the luminaire network. Further, one or more electronic devices (e.g., mobile devices) may couple to the luminaire network and may facilitate easy monitoring, configuration, and manual control of luminaires in the luminaire network, even when remotely connected to the luminaire network (e.g., via the cloud).

Abstract: A low voltage lighting system including a fixture (200) having an array of LEDs (204) and an LED driver circuit (202). The LED driver circuit (202) includes a Switch-mode Power Supply (SMPS) unit (206), a current sensing unit (210), a control unit (208) and a dimming input level shifting and signal conditioning unit (212). The SMPS unit (206) produces an adequate DC power (+VLED, ?VLED) for driving the LEDs (204). The control unit (208) receives a sensed current signal from the current sensing unit (210) and controls the SMPS unit (206) to maintain the output current within a pre-determined range. The control unit (208) receives a dimming signal from the dimming unit (212) or an emergency signal from a supply unit (104) to alter the output power of the SMPS unit (206) from normal mode to dimming mode or emergency mode respectively.

Abstract: The present disclosure relates to the field of lighting systems. The collective dissipation of heat by various components of lighting systems, inside a conventional single compartment enclosure, raises the temperature of each of the components, resulting in damage and reduction in the life of the components. The present disclosure, therefore, envisages an enclosure for lighting systems which is compartmentalized, and prevents overheating of the components of the lighting systems. The enclosure includes a first compartment and a second compartment. At least one driver is receivable in the first compartment and at least one light emitting component is receivable in the second compartment. The first compartment is insulated from the second compartment. The enclosure is primarily used for lighting fixtures which require high efficiency operation from a compact package, or lighting fixtures which operate in rugged environments at high temperatures.
