Abstract
Display system comprising a number of lamp holders which each have a local control unit and which are suitable for holding and connecting to the local control unit a lamp, the local control units of the various lamp holders being connected to a common conductor bundle to which a central control unit and a supply unit are also connected. Each local control unit contains an address. If a local control unit receives a message containing the address of the local control unit from the conductor bundle it responds, depending on any other content of the message, for optionally activating the associated lamp, for optionally changing the address and for sending back a message which specifies the conducting state between connections for the lamp.
Claims5
Light emitter system comprising a plurality of light emitters and a central control unit, each of the light emitters being mounted in a holder and each of the light emitters being connected to the central control unit via connections of the holders and conductors such that the light emitters are selectively activated by the central control unit, each said holder having a local control unit which is connected to the light emitter of the associated holder and, via the conductors, to the central control unit, the local control unit having a writable memory in which during manufacturing an original address is stored and in which during installation an operational address allocated to the associated local control unit is stored, the local control unit being suitable for recognizing the presence of a properly operating light emitter, wherein the central control unit accesses the local control unit by transmitting messages so as to optionally activate the associated light emitter, and to optionally change the original address to the operational address, the local control unit being configured to send to the central control unit a message containing locally detected information and wherein in response to a message transmitted from the central control unit, the local control unit does not send a message to the central control unit if both original address is stored in the associated memory, and the locally detected information corresponds to a state indicating an absence of a properly operating light emitter in the associated holder.
Holder for a light emitter, comprising holding means, two first electrical contacts, electrical supply terminals being connected to the first contacts, the holding means being suitable for holding the light emitter in such a way that the first contacts are in contact with the light emitter, and a control unit which is connected to the first contacts, the control unit having a writable memory in which an original address, determined when manufacturing control unit, and an operational address, allocated to the control unit during installation, are stored, the control unit being suitable for recognizing the presence of a properly operating light emitter, wherein the control unit being suitable for receiving a message, and on receiving the control unit being suitable for optionally activating the light emitter, for optionally changing the original address to the operational address and for optionally sending a message containing locally detected information, wherein the control unit does not send a message if both the original address is stored in the memory and the locally detected information corresponds to a state indicating an absence of a properly operating light emitter.
