PRESENCE DETECTION USING SPLIT BEAM LUMINAIRE |
摘要 |
The invention relates to a method for determining presence of objects in an area (207) surrounding a luminaire (200). The luminaire (200) includes a first light source (203), a second light source (205), and a sensor (216). The first light source (203) is configured to emit a first light beam (204) adapted to illuminate a first predefined area. The second light source (205) is configured to emit a second light beam (206) adapted to illuminate a background area surrounding the first predefined area. The sensor (216) is configured to detect a back-reflected first light beam (210) and a back-reflected second light beam (212). The method includes determining whether objects are present in the area surrounding the luminaire based on a comparison of information indicative of a signal strength of the detected back-reflected first light beam (210) and information indicative of a signal strength of the detected back-reflected second light beam (212). |
