Embodiment Construction

[0032] First refer to figure 1 , figure 1 A schematic block diagram of a luminaire 100 is illustrated. It will be appreciated that luminaire 100 may include figure 1 other components and connections not shown.

[0033] Luminaire 100 includes a control module 102 coupled to at least one light source 114 and at least one sensor 104 . Such as figure 1 As shown in , the control module 102 is arranged to receive sensor output signals from each of the sensors 104 . Control module 102 is configured to communicate with components of luminaire 100 based on sensor output signals received from sensor 104 .

[0034] Such as figure 1 As shown in , the sensor 104 may include a microphone 106 configured to provide a microphone output signal to the control module 102 . The microphone 106 is arranged to protrude from the housing of the luminaire 100 to enable the microphone 106 to receive audio signals from the outdoor environment of the luminaire 100 . In this context, the control mod...

Abstract

A luminaire comprising: at least one light source arranged to emit light to illuminate an outdoor environment of the luminaire; at least one sensor, each of the at least one sensor arranged to provide a sensor output signal; a control module arranged to receive the sensor output signal from each of the at least one sensor and configured to communicate with a component of the luminaire based on the at least one sensor output signal; and a precipitation detection module arranged to receive the at least one sensor output signal and configured to detect occurrence of precipitation in the outdoor environment based on the at least one sensor output signal and control the light emitted from the at least one light source based on said detection.

Description

technical field [0001] The present disclosure relates to precipitation sensing. In particular, the present disclosure relates to precipitation sensing enabled by outdoor luminaires. Background technique [0002] In lighting installations for intelligent light control, there is an increasing demand for sensor-driven lighting control systems with integrated sensors (presence, motion, moving object type, etc.) because of their ability to reduce the energy consumption of their light sources and This increases the advantages of cost savings and the lifetime of the light source. [0003] A range of sensing functions are integrated into light poles ranging from presence sensing (for light control), orientation sensing (luminaire diagnostics) to environmental monitoring. Presence sensing allows the light sources of the lighting system to be turned off or dimmed when no people or objects are present in the space, and conversely turned on or brightened when people or objects are pre...
