摘要:
The present invention relates to a lighting system(10) arranged to control a light intensity and a color temperature of light in a room(1). The lighting system comprising: a light source(12) arranged to emit light, the light source(12) comprising a first and second light emitters(13, 14) each being adjustable between a number of light intensity levels and arranged to emit light having a first and second color temperature,respectively. The light source(12) is arranged to provide an output signal(OS) comprising information pertaining to a light intensity level of said first and second light emitters(13, 14), respectively; a light sensor(16) arranged to measure the light intensity and the color temperature of the light in the room, and to provide a sense signal(SS) comprising information pertaining to the measured light intensity and color temperature; and a controller(18) arranged to control the color temperature and the light intensity of the light in the room(1)by adjusting the light intensity level of said first and second light emitters(13, 14), based on said sense signal(SS) provided by the light sensor(16)and said output signal(OS)provided by the light source(12).
摘要:
The present invention relates generally to the field of occupancy detection, and more particularly to an occupancy detection system and a corresponding method suitable for a presence controlled system. A method and system for determining occupancy of a room is provided, in which a signal from a movement sensor positioned in the room is analyzed to detect variations in the signal which correspond to movements of an occupant of the room. The room is determined to be empty if in the received signal a leave pattern is identified. The leave pattern is a predetermined pattern which has been associated with an occupant leaving the room. The method and system provide reliable occupancy detection in more or less static environments like for instance offices, and when utilized in for instance a presence controlled lighting system, the number of frustrating erroneous “switch-off” events of the light in a situation where a room is still occupied by occupants involved in relative still/static activities is then decreased.

Methods and devices are disclosed for a reusable PaYG dongle (10) including a data connection (11) arranged to connect to one or more PaYG products (20) and transfer data (17) to the one or more PaYG product (20) and an input unit arranged to receive an external signal (18). A controller (12) is arranged to process the external signal (18) and transfer the enable signal (17) using the data connection (11) to the one or more PaYG products (20) based upon the external signal (18). The methods are for enabling the one or more PaYG products (20) using the reusable PaYG dongle (10).
