In order to be able to control such complex lighting systems, are normally used high-speed control consoles performance. Since the entire show is based on the 2 0 console of control ll or , usually there is a console of backup in case of failure of the main console. Also, if the show exceeds the number of parameters controllable from the control console, they are used control modules to distribute the show on 2 5 different processing units. Each control module of the lighting is equipped with a digital processor that enables the digital processing of data and signals and a memory that allows you to store programs lighting and then access it when needed. Each control module is normally used for the control of subgroups of devices the lighting. However, this structure implies that a simple malfunction of a single control module impacts the show significantly, determining 1 0 a malfunction of all lighting fixtures controlled by the malfunctioning control module. T o ensure operational safety even in the event of failure of individual control modules, the systems currently known lighting systems therefore also provide for 1 5 this case, the use of backup control modules. This redundancy leads to a significant increase in costs also in terms of connection infrastructure. The more devices are deployed on the network, the more increases the complexity of redundancy and reliability. 2 0 It is an object of the present invention to provide a lighting system that is free of the inconveniences here highlighted in the prior art; in particular, it is a purpose of the invention that of providing a lighting system which allows the above-mentioned drawbacks to be overcome 2 5 in a simple and reliable way, both from the point of view functional, both from a cos tru ct point of view.

D escription of a form of implementation of the invention Referring to the attached figures, figure 1 shows a stage lighting system in accordance with the This invention comprising a plurality of apparatus 2 5 of lighting 2 , a control console 1 or 3 , and a network connection 4 between the control console 3 and the lighting fixtures 2. With reference to figures 2 and 3, each device of lighting 2 is provided with at least one source group 8 (not visible in detail) configured to generate one or more bright beams, of a control device or 9 configured to regulate at least one source group &8. Preferably, each luminaire 2 also includes one or more beam processing elements 1 0 (not illustrated in the attached figures) arranged downstream of the source group along the optical path of the generated beam from the source group and configured to selectively modify the characteristics of the light beam according to to operational needs. The processing devices of the 1 5 beam, when present, are normally regulated by the control device 9. Each lighting fixture 2 is equipped with also of a digital memory 11 configured for 1"storage of lighting and / or program data and / or programs 2 0 a digital processor 12 in communication with the memory digital 11 and configured to process signals, data and lighting programs and send control signals to the control device 8. ⑪ digital processor 12 and preferably a 2 5 distributed NPU (Network Processing Unit) processor in a network エ P . In essence, the 12 digital processor and a processor software programmable and application-optimized of the network. The lighting programs stored in the memory of each lighting fixture 2 are preferably fragments of a lighting program overall that concern the respective appliance lighting 2. 1 0 In other words, the light designer designs a program of overall lighting involving several lighting fixtures and is composed of fragments of program. Typically, the lighting program overall it is composed of a number of program fragments 1 5 substantially identical to the number of devices of the lighting affected by that same program overall lighting. Each program fragment will regulate the behavior of a specific device lighting 1affected by the lighting program 2 0 total. In the non-limiting example described here and illustrated, the 2 lighting fixtures illustrated They are all moving head projectors. It is understood that the lighting system 1 according to the present invention 2 5 may also include lighting fixtures 2 of different typology such as led walls, screens, stroboscopic sources, etc. While moving head projectors can be of different typology, they have in common the presence of a casing 16 (which we will define generically here and in the following head 16), inside which the group is arranged source 8 and any processing devices beam, and a support group 17 configured for support the head ⑯ . 1 0 Support group 17 is configured to allow head 16 to rotate around two axes orthogonal, commonly called PAN and TILT. For duesto This is why these projectors are called “moving heads”. In particular, support group 3 includes a 1 5 base 18 and a fork 19. The fork 19 is coupled to the base 18 rotatable around the PAN axis. The fork 19 supports the head 16 so that it can rotate around the axis TILT. The movement of the head 16 is regulated by the control device 9. 2 0 P referably, at least the memory type 11 and the digital processor 12 are housed in the base 18. In the example illustrated also the device of control 9 and housed in base 18. The control console 3 is in data communication with 2 5 lighting devices 2 affected by the programs lighting via the connection network 4. Preferably, the control console ll or 3 ein data communication with at least the 12 digital processor of the lighting fixtures 2 affected by the programs lighting. In particular, the control console is configured to send at least one reference clock signal (Rclock) simultaneously with the 12 digital processors of the lighting fixtures 2. 1 0 Thanks to the reference clock signal (Rclock) the 12 digital processors ©can perform their respective lighting programs synchronously. In other words, the lighting programs in the 12 digital processors are run using 11 1 5 reference clock signal sent from the console control 3. The execution of the lighting programs by of the digital processor 12 involves 1''sending signals to the lighting fixture control device 9 2 0 2 in order to 1implement the program specifications lighting. Communication network 4 is a communication network data and can be defined by a connection network via cable or from a wireless connection network. 2 5 Advantageously, the reference clock signal can be powered by 12 different digital processors lighting fixtures 2 through networks of communications that may already exist. Therefore, there is no requires a communication network dedicated to sending only of the reference clock signal. Preferably, the reference clock signal is emitted at a certain frequency, so that cons entire a temporal synchronization of the processors digital 12 of all lighting fixtures 2 1 0 involved. Preferably, the control console 3 includes also control commands that allow control independent of some parameters of the devices lighting 2. 1 5 Preferably, the control console 3 and configured to allow remote access to the processor 12 digital and 11 digital memories of the various devices of lighting 2. In this way, before the show, the light designer can store in different memories 2 0 digital displays of the different lighting fixtures 2 respective fragments of the lighting program overall and possibly test the individual fragments to remote. The lighting system 1 according to this 2 5 invention has some important advantages. First of all, the lighting system 1 according to the This invention has a simplified infrastructure that It does not provide for redundancies. Furthermore, sending a simple clock signal is reference involves a significant simplification of the connection infrastructure. For example, they are sufficient Ethernet cables. Sending reference clock signals from the con sole control 3 to lighting fixtures 2 free 1 0 bandwidth in the connection network 4. The free bandwidth can be used for other purposes: for example, maintenance and monitoring, RDM, overriding manual, status of the channels of the devices, tracking systems, etc. The pud clock signal distribution protocol 1 5 also be open source. In this way any existing control console can implement the solution according to the present invention (also the consoles of controls that do not normally work with NPU - Network Processing Unit) 2 0 The simplification of the console functions control allows, among other things, to use consoles smaller dimensions. The consul against number 3, in fact, has the only function of sending the reference clock signal during the show. The loading activities of the 2 5 program fragments in individual digital processors 1 0 are performed in a non-critical phase of the show. Finally, this solution may prove to be particularly advantageous also for 1 programs of pixel mapping type lighting that involves usually more than one projector to achieve graphic effects overall distributed on the projectors and arranged according to a certain criterion. In other words, these effects use the projections tt oricomesefo sse ro , overall , a screen where pixels are defined by individual source groups of the 1 0 projectors involved. Finally, it is evident that the system and the method here changes may be made to the descriptions and illustrations and variants without leaving the protective scope of the present invention, as defined in the claims 1 5 attached of the attached claims.
