Abstract: A lighting system (100) for illuminating an environment and a method of starting the installation of a program on a programmable controller of a lighting module are provided. The lighting system (100) comprises a particular lighting module (110), a neighboring lighting module (120) and an installation decision generator (112). A portion of the environment is illuminated by both lighting modules (110, 120). Both lighting modules (110, 120) have a programmable controller (114, 124) and may receive a program via a network interface for installation on the programmable controller (114, 124). The installation decision generator (112) decides whether the installation of the program on the particular lighting module (110) may start, based on operational information as to whether the light emission capabilities of the neighboring lighting module (120) enable illumination of the portion of the environment to be sufficiently close to a desired illumination of the portion.

Abstract: In a lighting device, a primary control unit (103) and a group of light units (107) are arranged in a power supply chain, each light unit (107) of said group being arranged for receiving commands from the primary control unit (103) via a light unit interface (117) of the light unit (107), wherein each succeeding unit (103; 107) of the chain has a power input (145) which is connected to a switchable power output (147) of a respective preceding unit (103; 107), each preceding unit (103; 107) being arranged to supply power at the power output (147) only after initializing an address identification of the unit, and each succeeding unit (103; 107) being arranged to initialize an address identification of the unit upon being supplied with power at the power input (145).

Abstract: In a lighting device (101), a primary control unit (103) is arranged to select, on the basis of an obtained lighting device control command, a broadcast communication mode or an addressing communication mode of a control unit interface (113), and to communicate at least one light generation control command to at least one light unit interface (117) of at least one respective light unit (107) of a group of light units (107) of the lighting device (101) via a control unit interface (113) of the primary control unit (103) using the selected communication mode.

Abstract: An apparatus is described for recording an optical record carrier (40). The apparatus is arranged for recording a visually detectable pattern (LBL) at the record carrier in a ring shaped zone (RP). The apparatus is further arranged to record data (Data1, Data2) and a primary data organizing system (FS) wherein the data is organized. The primary data organizing system (FS) does not refer to a physical address within the ring shaped zone. The apparatus is further arranged for recording at least part of the data (Data2) or the primary data organizing system on the record carrier at an area peripherally arranged with respect to the ring shaped zone.

Abstract: A system is described comprising an optical record carrier and an apparatus for recording the optical record carrier. The apparatus comprises a facility (20) for generating a visually detectable pattern at a physical location on the record carrier (40), and a facility (20) for storing pattern information. The pattern information comprises at least first information indicative for the physical location.

Abstract: An apparatus is described for recording a visually detectable pattern on a record carrier (40), comprising a first (10) and a second module (20). The first module (10) is arranged for: receiving information that specifies the visually detectable pattern, issuing a request to the second module to provide indications, indicative for capabilities of recording the visually detectable pattern at the record carrier, issuing instructions for applying the visually detectable pattern at the record carrier using the received information, depending on the indicated capabilities of recording, and wherein the second module (20) is arranged for providing the requested indications, and generating the visually detectable pattern at the record carrier (40) using the issued instructions.
