Abstract:
In various embodiments, a lighting control apparatus (100) may include logic such as a controller (102, 202, 302, 502) and a thermal imaging sensor (108, 208, 308, 408a-b, 508) operably coupled with the controller. The thermal imaging sensor may have at least one field of view (110, 210, 310, 410a-b, 510) pointed at a surface (112, 212, 312, 412a-b, 512, 612). The surface may exhibit various degrees of thermal conductivity. The controller may be configured to: receive a signal from the thermal imaging sensor, the signal being indicative of heat (114) captured by the surface and sensed by the thermal imaging sensor. Based on the signal received from the thermal imaging sensor, the controller may cause one or more light sources (104, 204, 304, 504) to emit light having one or more selected properties.
Abstract:
A backup power supply module (10) for an LED light fitting comprises an AC–DC converter (16), a DC–DC converter (50), a battery (40), a controller (100), sensing means (14, 114) arranged to detect whether power is supplied to the AC–DC converter (16), and switching means (20, 22, 24) for switching the module between a passive state and an active state. The module switches from passive state to active state if power supply to the AC–DC converter (16) is lost. In the passive state, the AC–DC converter (16) charges the battery (40) and powers the controller (100), and the DC–DC converter (50) is disconnected from the battery (40) and/or the LEDs (4) of a light fitting (1). In the active state, the battery (40) powers the controller (100) and supplies power to the LEDs (4) via the DC–DC converter (50), and the controller (100) controls the DC–DC converter (50) to supply a substantially constant current to the LEDs (4).
