Abstract

A method (400) for identifying precipitation (50) includes the steps of: providing (410) a lighting unit (10) having a first photosensor (32), a second photosensor (34), and a controller (22), where the first and second photosensors are vertically spaced by a first distance; receiving (430), by the first photosensor, a first light signal from the precipitation at a first time point (T1); receiving(440), by the second photosensor, a second light signal from the precipitation at a second time point (T2); calculating (450) the amount of time between the first light signal and the second light signal; and calculating (460), based on the first distance and the calculated amount of time between the first light signal and the second light signal, a velocity of the precipitation.

Description

technical field [0001] The present disclosure generally relates to methods and lighting systems configured to detect precipitation, and more particularly, to precipitation detection by outdoor lighting units. Background technique [0002] The development of smart lighting has led to an increased demand for integrated sensing solutions including presence detection, motion detection, etc. in lighting systems and luminaires. A wide range of functions are integrated into light poles, ranging from presence sensing for light control, orientation sensing for luminaire diagnostics, and environmental monitoring, in addition to other smart lighting systems. In order to allow mass market penetration of smart lighting networks, there is also a strong need for many sensing functions by integrating a minimum number of sensing modes. [0003] Precipitation detection is a sensing function that may be desirable in lighting systems and luminaires, especially those located outdoors. However,...
