    • A presence detection systemfor detecting presence of a living being (2) within an area (4), the systemcomprising a first light source (6a) providing light of a first spectrum, a first sensing means (8a;10a) which is arranged to filter the light of the first spectrum. The first sensing means produces a first presence detection signal (12a) based on the light of the first spectrumoriginated from the first light source and reflected from the living being (2). The presence detection system comprises a processor device (14) for concluding the living being's presence within the area (4) based on the first presence detection signal (12a). The processor device provides a position (22a) of the living being (2) within the area based on the intensityofthe first presence detection signal (12a) and based on the known position of the first light source (6a) within the area (4). The invention further relates to a lighting system comprising the above described presence detection system. Fig.
    • 一种存在检测系统,用于检测在区域(4)内存在生物(2)的系统,所述系统包括提供第一光谱的光的第一光源(6a),布置成过滤的第一感测装置(8a; 10a) 第一光谱的光。 第一感测装置基于从第一光源射出的第一光谱并从活体(2)反射的光产生第一存在检测信号(12a)。 存在检测系统包括:处理器装置(14),用于基于第一存在检测信号(12a),在区域(4)内总结生存状态。 处理器装置基于第一存在检测信号(12a)的强度并且基于区域(4)内的第一光源(6a)的已知位置,在区域内提供居住区域(2)的位置(22a) 。 本发明还涉及包括上述存在检测系统的照明系统。 图。
