• the invention further includes a network controller for a lighting network that includes a plurality of luminaires disposed in a space to be illuminated and a sensor system to detect user position within the space, the controller being configured to operate:
• Figure 1 is a schematic block diagram of a lighting network
• Figure 4 is a block diagram of a sensor for use in the network
• FIG. 7 illustrates an alternative, optical sensor
• Figure 9 is a block diagram of a commissioning process performed under the control of a program run by the central controller shown n Figure 1.
• Figure 1 illustrates a networked lighting system in that an array of luminaires Li,i, Li,2 are connected in a network 1 with control switches SW1 , SW2 and present sensors such as passive infrared (PIR) sensors SI , S2, under the control of a central controller 2.
• the network 1 may extend throughout the premises, for example on more than one floor.
• the premises may comprise an office building, warehouse or other commercial domestic premises.
• Suitable protocols for the network 1 include, but are not limited to, Digital Address Lighting Interface (DALI), Zigbee, LLM, Dianet, Star sense, ethernet and wi-fi.
• DALI Digital Address Lighting Interface
• LLM Zigbee
• Dianet Dianet
• Star sense ethernet
• wi-fi wi-fi.
• Each of the luminaires, switches and sensors has an individual, unique network address (such as an IP address) and control signals can be sent to and from them through the network in order to control operation of the luminaires.
• the example described herein by way of illustration may make use of the DALI protocol.
• a commissioning process needs to be carried out in order to associate individual luminaires with particular spaces within the premises to be controlled in a group either by the main controller 2 or individual associated switches and sensors S, SW.
• the main controller 2 is illustrated in more detail and comprises the processor 3 that is coupled through modem 4 to the network 1.
• the memory 5 includes amongst other things data concerning the network addresses of various switches, sensors and luminaires in the network so that control commands can be sent to them individually under the control of information provided through a data input 6. Operation of the network can be monitored from a control panel 7.
• the luminaire includes a processor 8 within associated memory 9 that holds an individual network address for the luminaire. Command signals are received from the controller 2 and associated switches and sensors through the network 1 via modem 10.
• the processor 8 controls a supply of electrical AC mains power from inlet 11 by means of a switch 12 that switches the AC supply to a lighting element 13, for example a fluorescent tube or other electrical lighting element.
• FIG 4 is a block diagram of the major components of one of the sensors and/or switches S and SW shown in Figure 1, which includes a processor 14 with an associated memory 15 that holds a network address.
• the processor 14 communicates with the network 1 through modem 16 and is powered by AC mains power 17.
• a manually operated switch element 18 for example a wall switch, provides on/off signals to the processor 14 which can be used to provide on/off signals that are fed to individual luminaires through the network by modem 16.
• FIG. 5 a plan view of premises that include a rectangular array of ceiling mounted luminaires is illustrated, comprising luminaires Li 1 . .. L 6 ,7 in a rectangular, equally spaced array.
• the space also includes an array of ceiling mounted PIR detectors as just described, with circular directive patterns covering areas A1-A4; B1-B4 and C1-C4.
• the areas of sensitivity of the sensors S are arranged to overlap.
• the area Al is overlapped by areas A2 and B l . This overlap is used in order to allow a positional discrimination to be achieved within the circular area of sensitivity of each PIR sensor S during the commissioning process.
• each of the luminaires sensors and switches have individual network addresses, they are not initially associated in groups, for example for illuminating particular work areas within the space shown in Figure 5.
• the commissioning actuator In order to perform commissioning, the luminaires to be included within a particular group are initially switched on manually by the person performing the commissioning, referred to herein as the commissioning actuator.
• the central controller 2 is switched into a commissioning mode during which the luminaires that have been switched on to be grouped together, send their individual network addresses from their respective memories 9 through their modems 10 and network 1 to controller 2, where they are stored temporarily in memory 5 for further processing.
• the commissioning actuator then walks or otherwise moves along a path around the group of luminaires that have been switched on.
• the luminaires that have been switched on to be formed into a group are shown as white circles in Figure 5 whereas the luminaires that remain switched off are shown in grey.
• the commissioning actuator walks along a path from position PI to P2. .. P8. When in position PI , the commissioning actuator is sensed solely by the sensor S associated with sensor area C 1. Similarly, in positions P2 and P3 the commissioning actuator sensed to be within sensor areas B l and Al respectively. However, at position P4, a commissioning actuator is sensed to be in both areas A2 and A3 concurrently.
• the sensors associated with the areas A, B, C transmit detection signals through the network 1 to the controller 2 and in this way, the controller 2 can build up series of coordinates of a path that extends around the luminaires that are to be included within the group.
• the resulting group can also be associated with individual ones of the switches SW.
• the commissioning process may be repeated for other groups or sub groups of luminaires within the premises.
• the commissioning actuator when travelling along the path P1-P8 defines coordinates that are sensed by the sensors so as to determine the region in the space that is to be associated with the group of luminaires. This avoids the need to switch on the luminaires individually and associate them with the group one-by-one at the central controller 2 by repeated journeys back and forth to the central controller 2 and the individual luminaires.
• the impulse functions will have a phase difference depending on the angle of the incidence of the acoustic wave from the commissioning actuator.
• the processor 24 calculates a correlation function between the two impulse functions detected by detectors 22, 23 and a processor 25 calculates the time difference between them, which in turn is used to by processor 26 to compute the direction from which the sound from the commissioning actuator emanates.
• the position of the commission actuator can be calculated by a position calculator 27 that receives acoustic signals concurrently from three of the detecting stations on lines 28-1, 28-2, 28-3 and so is able to triangulate the position of the commissioning actuator as he or she walks around the commissioning path PI - P8.
• the commissioning actuator may carry a device which makes a distinctive sound that can be readily detected by the detectors 22, 23 to aid in developing accurate positional data for the path P.
• the sensor 19 illustrated in Figure 4 comprises a fish eye camera as illustrated in Figure 7 which may for example be mounted in the middle of the array of luminaires shown in Figure 5.
• the fish eye camera shown schematically in Figure 7 comprises an image processing device 29 with a fish eye lens 30 that typically can produce an image over an approximately half- sphere (360°) field of view.
• the process performed by the processing device 29 comprises processing images of the field of view successively such that, as illustrated in Figure 8, the next occurring image at step S 8.1 is compared with a previous image taken at step S 8.2, which identifies changes in the field of view.
• the positional data of the path is associated with the sensor addresses S for the group so that the group can be switched on or off when a person enters the region in which the luminaires of the group are located. Additionally, if desired, individual switches SWl etc can be associated with the group so that the group of luminaires can be manually switched on and off by a local switch or the like.
• step S9.5 the group is commissioned as a group in the memory of the controller and the device sends switches to operational mode at step S9.6.
